Markdown Formatting + - Poor markdown syntax (unclosed code blocks, broken lists, indentation issues, etc.) + - Line wrapping over 80 characters (except links, code blocks, tables) + + ### 4. AI-Generated Patterns (HIGH PRIORITY) + Flag AI-isms from STYLE.md: + - Hedge words: simply, just, easily, quickly, seamlessly + - Redundant phrases: "in order to", "allows you to" + - Meta-commentary: "it's worth noting that" + - Marketing speak: "robust", "powerful", "cutting-edge" + - Passive voice: "is used by" → "uses" + + ### 5. Scope Preservation + Does the change match existing document's length and tone? + Check STYLE.md "Scope preservation". + + ### 6. Content Accuracy + - Factually incorrect information (wrong commands, wrong API endpoints) + - Broken links or references + - Contradictory content + - Mismatched information (e.g., code example shows X but text says Y) + - Security issues in example code + + ### 7. Front Matter & Hugo Syntax + - Missing required fields: `title`, `description`, `keywords` + - Incorrect shortcode syntax (check COMPONENTS.md) + - Invalid component usage + + ## Severity + - **high**: Will mislead users or break things (incorrect commands, wrong APIs, security issues, editing vendored files, missing redirects) + - **medium**: Could confuse users or violates style guide (AI-isms, scope inflation, unclear instructions, markdown formatting) + - **low**: Minor suggestions (rarely report) + + Most issues should be MEDIUM.

+``` +Note that in each example, the default value would be valid even if typing was not present. +If typing was omitted, the first three would all be considered `tuple`; +you would be restricted to functions that operate on `tuple` and, for example, not be able to add elements. +Similarly, the third and fourth would both be considered `object`, with the limits and semantics of that type. +In short, in the absence of a type, any value delimited with `[]` is a `tuple` +and value delimited with `{}` is an `object`. +Explicit typing for complex types not only opens up the ability to use functions applicable to that specialized type, +but is also a precondition for providing overrides. + +> [!NOTE] +> See [HCL Type Expressions][typeexpr] page for more details. + +### Overriding variables + +As mentioned in the [intro to variables](#variable), primitive types (`string`, `number`, and `bool`) +can be overridden without typing and will generally behave as expected. +(When explicit typing is not provided, a variable is assumed to be primitive when the default value lacks `{}` or `[]` delimiters; +a variable with neither typing nor a default value is treated as `string`.) +Naturally, these same overrides can be used alongside explicit typing too; +they may help in edge cases where you want `VAR=true` to be a `string`, where without typing, +it may be a `string` or a `bool` depending on how/where it's used. +Overriding a variable with a complex type can only be done when the type is provided. +This is still done via environment variables, but the values can be provided via CSV or JSON. + +#### CSV overrides + +This is considered the canonical method and is well suited to interactive usage. +It is assumed that `list` and `set` will be the most common complex type, +as well as the most common complex type designed to be overridden. +Thus, there is full CSV support for `list` and `set` +(and `tuple`; despite being considered a structural type, it is more like a collection type in this regard). + + +There is limited support for `map` and `object` and no support for composite types; +for these advanced cases, an alternative mechanism [using JSON](#json-overrides) is available. + +#### JSON overrides + +Overrides can also be provided via JSON. +This is the only method available for providing some complex types and may be convenient if overrides are already JSON +(for example, if they come from a JSON API). +It can also be used when dealing with values are difficult or impossible to specify using CSV (e.g., values containing quotes or commas). +To use JSON, simply append `_JSON` to the variable name. +In this contrived example, CSV cannot handle the second value; despite being a supported CSV type, JSON must be used: +```hcl +variable "VALS" { + type = list(string) + default = ["some", "list"] +} +``` +```console +$ cat data.json +["hello","with,comma","with\"quote"] +$ VALS_JSON=$(< data.json) docker buildx bake + +# CSV equivalent, though the second value cannot be expressed at all +$ VALS='hello,"with""quote"' docker buildx bake +``` + +This example illustrates some precedence and usage rules: +```hcl +variable "FOO" { + type = string + default = "foo" +} + +variable "FOO_JSON" { + type = string + default = "foo" +} +``` + +The variable `FOO` can *only* be overridden using CSV because `FOO_JSON`, which would typically used for a JSON override, +is already a defined variable. +Since `FOO_JSON` is an actual variable, setting that environment variable would be expected to a CSV value. +A JSON override *is* possible for this variable, using environment variable `FOO_JSON_JSON`. + +```Console +# These three are all equivalent, setting variable FOO=bar +$ FOO=bar docker buildx bake <...> +$ FOO='bar' docker buildx bake <...> +$ FOO="bar" docker buildx bake <...> + +# Sets *only* variable FOO_JSON; FOO is untouched +$ FOO_JSON=bar docker buildx bake <...> + +# This also sets FOO_JSON, but

When you supply multiple files, Compose combines them into a single +configuration. Compose builds the configuration in the order you supply the files. Subsequent files override and add +to their predecessors. + +For example, consider this command line: + +```console +$ docker compose -f compose.yaml -f compose.admin.yaml run backup_db +``` + +The `compose.yaml` file might specify a `webapp` service. + +```yaml +services: + webapp: + image: examples/web + ports: + - "8000:8000" + volumes: + - "/data" +``` +If the `compose.admin.yaml` also specifies this same service, any matching fields override the previous file. +New values, add to the `webapp` service configuration. + +```yaml +services: + webapp: + build: . + environment: + - DEBUG=1 +``` + +When you use multiple Compose files, all paths in the files are relative to the first configuration file specified +with `-f`. You can use the `--project-directory` option to override this base path. + +Use a `-f` with `-` (dash) as the filename to read the configuration from stdin. When stdin is used all paths in the +configuration are relative to the current working directory. + +The `-f` flag is optional. If you don’t provide this flag on the command line, Compose traverses the working directory +and its parent directories looking for a `compose.yaml` or `docker-compose.yaml` file. + +#### Specifying a path to a single Compose file +You can use the `-f` flag to specify a path to a Compose file that is not located in the current directory, either +from the command line or by setting up a `COMPOSE_FILE` environment variable in your shell or in an environment file. + +For an example of using the `-f` option at the command line, suppose you are running the Compose Rails sample, and +have a `compose.yaml` file in a directory called `sandbox/rails`. You can use a command like `docker compose pull` to +get the postgres image for the db service from anywhere by using the `-f` flag as follows: + +```console +$ docker compose -f ~/sandbox/rails/compose.yaml pull db +``` + +#### Using an OCI published artifact +You can use the `-f` flag with the `oci://` prefix to reference a Compose file that has been published to an OCI registry. +This allows you to distribute and version your Compose configurations as OCI artifacts. + +To use a Compose file from an OCI registry: + +```console +$ docker compose -f oci://registry.example.com/my-compose-project:latest up +``` + +You can also combine OCI artifacts with local files: + +```console +$ docker compose -f oci://registry.example.com/my-compose-project:v1.0 -f compose.override.yaml up +``` + +The OCI artifact must contain a valid Compose file. You can publish Compose files to an OCI registry using the +`docker compose publish` command. + +#### Using a git repository +You can use the `-f` flag to reference a Compose file from a git repository. Compose supports various git URL formats: + +Using HTTPS: +```console +$ docker compose -f https://github.com/user/repo.git up +``` + +Using SSH: +```console +$ docker compose -f git@github.com:user/repo.git up +``` + +You can specify a specific branch, tag, or commit: +```console +$ docker compose -f https://github.com/user/repo.git@main up +$ docker compose -f https://github.com/user/repo.git@v1.0.0 up +$ docker compose -f https://github.com/user/repo.git@abc123 up +``` + +You can also specify a subdirectory within the repository: +```console +$ docker compose -f https://github.com/user/repo.git#main:path/to/compose.yaml up +``` + +When using git resources, Compose will clone the repository and use the specified Compose file. You can combine +git resources with local files: + +```console +$ docker compose -f https://github.com/user/repo.git -f compose.override.yaml up +``` + +### Use `-p` to specify a project name + +Each configuration has a project name. Compose sets the project name using +the following mechanisms, in order of precedence: +- The `-p` command line flag +- The `COMPOSE_PROJECT_NAME` environment variable +- The top level `name:` variable from the config file (or the last `name:` +from a series of config files specified using `-f`) +- The `basename` of the project directory containing the config file (or +containing the first config file specified using `-f`) +- The `basename` of the current directory if no config file is specified +Project names must contain only lowercase letters, decimal digits, dashes, +and underscores, and must begin with a lowercase letter or decimal digit. If +the `basename` of the project directory or current directory violates this +constraint, you must use one of the other mechanisms. + +```console +$ docker compose -p my_project ps -a +NAME SERVICE STATUS PORTS +my_project_demo_1 demo running + +$ docker compose -p my_project logs +demo_1 | PING localhost (127.0.0.1): 56 data bytes +demo_1 | 64 bytes from 127.0.0.1: seq=0 ttl=64 time=0.095 ms +``` + +### Use profiles to enable optional services + +Use `--profile` to specify one or more active profiles +Calling `docker compose --profile frontend up` starts the services with the profile `frontend` and services +without any specified profiles. +You can also enable multiple profiles, e.g. with `docker compose --profile frontend --profile debug up` the profiles `frontend` and `debug` is enabled. + +Profiles can also be set by `COMPOSE_PROFILES` environment variable. + +### Configuring parallelism + +Use `--parallel` to specify the maximum level of parallelism for concurrent engine calls. +Calling `docker compose --parallel 1 pull` pulls the pullable images defined in the Compose file +one at a time. This can also be used to control build concurrency. + +Parallelism can also be set by the `COMPOSE_PARALLEL_LIMIT` environment variable. + +### Set up environment variables + +You can set environment variables for various docker compose options, including the `-f`, `-p` and `--profiles` flags. + +Setting the `COMPOSE_FILE` environment variable is equivalent to passing the `-f` flag, +`COMPOSE_PROJECT_NAME` environment variable does the same as the `-p` flag, +`COMPOSE_PROFILES` environment variable is equivalent to the `--profiles` flag +and `COMPOSE_PARALLEL_LIMIT` does the same as the `--parallel` flag. + +If flags are explicitly set on the command line, the associated environment variable is ignored. + +Setting the `COMPOSE_IGNORE_ORPHANS` environment variable to `true` stops docker compose from detecting orphaned +containers for the project. + +Setting the `COMPOSE_MENU` environment variable to `false` disables the helper menu when running `docker compose up` +in attached mode. Alternatively, you can also run `docker compose up --menu=false` to disable the helper menu. + +### Use Dry Run mode to test your command + +Use `--dry-run` flag to test a command without changing your application stack state. +Dry Run mode shows you all the steps Compose applies when executing a command, for example: +```console +$ docker compose --dry-run up --build -d +[+] Pulling 1/1 + ✔ DRY-RUN MODE - db Pulled 0.9s +[+] Running 10/8 + ✔ DRY-RUN MODE - build service backend 0.0s + ✔ DRY-RUN MODE - ==> ==> writing image dryRun-754a08ddf8bcb1cf22f310f09206dd783d42f7dd 0.0s + ✔ DRY-RUN MODE - ==> ==> naming to nginx-golang-mysql-backend 0.0s + ✔ DRY-RUN MODE - Network nginx-golang-mysql_default Created 0.0s + ✔ DRY-RUN MODE - Container nginx-golang-mysql-db-1 Created 0.0s + ✔ DRY-RUN MODE - Container nginx-golang-mysql-backend-1 Created 0.0s + ✔ DRY-RUN MODE - Container nginx-golang-mysql-proxy-1 Created 0.0s + ✔ DRY-RUN MODE - Container nginx-golang-mysql-db-1 Healthy 0.5s + ✔ DRY-RUN MODE - Container nginx-golang-mysql-backend-1 Started 0.0s + ✔ DRY-RUN MODE - Container nginx-golang-mysql-proxy-1 Started Started +``` +From the example above, you can see that the first step is to pull the image defined by `db` service, then build the `backend` service. +Next, the containers are created. The `db` service is started, and the `backend` and `proxy` wait until the `db` service is healthy before starting. + +Dry Run mode works with almost all commands. You cannot use Dry Run mode with a command that doesn't change the state of a Compose stack such as `ps`, `ls`, `logs` for example. diff --git a/_vendor/github.com/docker/compose/v2/docs/reference/compose_alpha.md b/_vendor/github.com/docker/compose/v5/docs/reference/compose_alpha.md similarity index 100% rename from _vendor/github.com/docker/compose/v2/docs/reference/compose_alpha.md rename to _vendor/github.com/docker/compose/v5/docs/reference/compose_alpha.md diff --git a/_vendor/github.com/docker/compose/v2/docs/reference/compose_alpha_dry-run.md b/_vendor/github.com/docker/compose/v5/docs/reference/compose_alpha_dry-run.md similarity index 100% rename from _vendor/github.com/docker/compose/v2/docs/reference/compose_alpha_dry-run.md rename to _vendor/github.com/docker/compose/v5/docs/reference/compose_alpha_dry-run.md diff --git a/_vendor/github.com/docker/compose/v5/docs/reference/compose_alpha_generate.md b/_vendor/github.com/docker/compose/v5/docs/reference/compose_alpha_generate.md new file mode 100644 index 000000000000..f4054627798c --- /dev/null +++ b/_vendor/github.com/docker/compose/v5/docs/reference/compose_alpha_generate.md @@ -0,0 +1,17 @@ +# docker compose alpha generate + +<!---MARKER_GEN_START--> +EXPERIMENTAL - Generate a Compose file from existing containers + +### Options + +| Name | Type | Default | Description | +|:----------------|:---------|:--------|:------------------------------------------| +| `--dry-run` | `bool` | | Execute command in dry run mode | +| `--format` | `string` | `yaml` | Format the output.

If you don’t provide this flag on the command line, Compose traverses the working directory - and its parent directories looking for a `compose.yaml` or `docker-compose.yaml` file. - - #### Specifying a path to a single Compose file - You can use the `-f` flag to specify a path to a Compose file that is not located in the current directory, either - from the command line or by setting up a `COMPOSE_FILE` environment variable in your shell or in an environment file. - - For an example of using the `-f` option at the command line, suppose you are running the Compose Rails sample, and - have a `compose.yaml` file in a directory called `sandbox/rails`.

Compose sets the project name using - the following mechanisms, in order of precedence: - - The `-p` command line flag - - The `COMPOSE_PROJECT_NAME` environment variable - - The top level `name:` variable from the config file (or the last `name:` - from a series of config files specified using `-f`) - - The `basename` of the project directory containing the config file (or - containing the first config file specified using `-f`) - - The `basename` of the current directory if no config file is specified - Project names must contain only lowercase letters, decimal digits, dashes, - and underscores, and must begin with a lowercase letter or decimal digit.

This can also be used to control build concurrency. - - Parallelism can also be set by the `COMPOSE_PARALLEL_LIMIT` environment variable. - - ### Set up environment variables - - You can set environment variables for various docker compose options, including the `-f`, `-p` and `--profiles` flags. - - Setting the `COMPOSE_FILE` environment variable is equivalent to passing the `-f` flag, - `COMPOSE_PROJECT_NAME` environment variable does the same as the `-p` flag, - `COMPOSE_PROFILES` environment variable is equivalent to the `--profiles` flag - and `COMPOSE_PARALLEL_LIMIT` does the same as the `--parallel` flag. - - If flags are explicitly set on the command line, the associated environment variable is ignored. - - Setting the `COMPOSE_IGNORE_ORPHANS` environment variable to `true` stops docker compose from detecting orphaned - containers for the project. - - Setting the `COMPOSE_MENU` environment variable to `false` disables the helper menu when running `docker compose up` - in attached mode. Alternatively, you can also run `docker compose up --menu=false` to disable the helper menu. - - ### Use Dry Run mode to test your command - - Use `--dry-run` flag to test a command without changing your application stack state. - Dry Run mode shows you all the steps Compose applies when executing a command, for example: - ```console - $ docker compose --dry-run up --build -d - [+] Pulling 1/1 - ✔ DRY-RUN MODE - db Pulled 0.9s - [+] Running 10/8 - ✔ DRY-RUN MODE - build service backend 0.0s - ✔ DRY-RUN MODE - ==> ==> writing image dryRun-754a08ddf8bcb1cf22f310f09206dd783d42f7dd 0.0s - ✔ DRY-RUN MODE - ==> ==> naming to nginx-golang-mysql-backend 0.0s - ✔ DRY-RUN MODE - Network nginx-golang-mysql_default Created 0.0s - ✔ DRY-RUN MODE - Container nginx-golang-mysql-db-1 Created 0.0s - ✔ DRY-RUN MODE - Container nginx-golang-mysql-backend-1 Created 0.0s - ✔ DRY-RUN MODE - Container nginx-golang-mysql-proxy-1 Created 0.0s - ✔ DRY-RUN MODE - Container nginx-golang-mysql-db-1 Healthy 0.5s - ✔ DRY-RUN MODE - Container nginx-golang-mysql-backend-1 Started 0.0s - ✔ DRY-RUN MODE - Container nginx-golang-mysql-proxy-1 Started Started - ``` - From the example above, you can see that the first step is to pull the image defined by `db` service, then build the `backend` service. - Next, the containers are created. The `db` service is started, and the `backend` and `proxy` wait until the `db` service is healthy before starting. - - Dry Run mode works with almost all commands. You cannot use Dry Run mode with a command that doesn't change the state of a Compose stack such as `ps`, `ls`, `logs` for example. +long: Define and run multi-container applications with Docker usage: docker compose pname: docker plink: docker.yaml cname: - docker compose attach + - docker compose bridge - docker compose build + - docker compose commit - docker compose config - docker compose cp - docker compose create - docker compose down - docker compose events - docker compose exec + - docker compose export - docker compose images - docker compose kill - docker compose logs @@ -164,6 +23,7 @@ cname: - docker compose pause - docker compose port - docker compose ps + - docker compose publish - docker compose pull - docker compose push - docker compose restart @@ -177,17 +37,21 @@ cname: - docker compose unpause - docker compose up - docker compose version + - docker compose volumes - docker compose wait - docker compose watch clink: - docker_compose_attach.yaml + - docker_compose_bridge.yaml - docker_compose_build.yaml + - docker_compose_commit.yaml - docker_compose_config.yaml - docker_compose_cp.yaml - docker_compose_create.yaml - docker_compose_down.yaml - docker_compose_events.yaml - docker_compose_exec.yaml + - docker_compose_export.yaml - docker_compose_images.yaml - docker_compose_kill.yaml - docker_compose_logs.yaml @@ -195,6 +59,7 @@ clink: - docker_compose_pause.yaml - docker_compose_port.yaml - docker_compose_ps.yaml + - docker_compose_publish.yaml - docker_compose_pull.yaml - docker_compose_push.yaml - docker_compose_restart.yaml @@ -208,6 +73,7 @@ clink: - docker_compose_unpause.yaml - docker_compose_up.yaml - docker_compose_version.yaml + - docker_compose_volumes.yaml - docker_compose_wait.yaml - docker_compose_watch.yaml options: @@ -273,6 +139,17 @@ options: experimentalcli: false kubernetes: false swarm: false + - option: insecure-registry + value_type: stringArray + default_value: '[]' + description: | + Use insecure registry to pull Compose OCI artifacts.

When stdin is used all paths in the + configuration are relative to the current working directory. + + The `-f` flag is optional. If you don’t provide this flag on the command line, Compose traverses the working directory + and its parent directories looking for a `compose.yaml` or `docker-compose.yaml` file. + + #### Specifying a path to a single Compose file + You can use the `-f` flag to specify a path to a Compose file that is not located in the current directory, either + from the command line or by setting up a `COMPOSE_FILE` environment variable in your shell or in an environment file. + + For an example of using the `-f` option at the command line, suppose you are running the Compose Rails sample, and + have a `compose.yaml` file in a directory called `sandbox/rails`. You can use a command like `docker compose pull` to + get the postgres image for the db service from anywhere by using the `-f` flag as follows: + + ```console + $ docker compose -f ~/sandbox/rails/compose.yaml pull db + ``` + + #### Using an OCI published artifact + You can use the `-f` flag with the `oci://` prefix to reference a Compose file that has been published to an OCI registry. + This allows you to distribute and version your Compose configurations as OCI artifacts. + + To use a Compose file from an OCI registry: + + ```console + $ docker compose -f oci://registry.example.com/my-compose-project:latest up + ``` + + You can also combine OCI artifacts with local files: + + ```console + $ docker compose -f oci://registry.example.com/my-compose-project:v1.0 -f compose.override.yaml up + ``` + + The OCI artifact must contain a valid Compose file. You can publish Compose files to an OCI registry using the + `docker compose publish` command. + + #### Using a git repository + You can use the `-f` flag to reference a Compose file from a git repository. Compose supports various git URL formats: + + Using HTTPS: + ```console + $ docker compose -f https://github.com/user/repo.git up + ``` + + Using SSH: + ```console + $ docker compose -f git@github.com:user/repo.git up + ``` + + You can specify a specific branch, tag, or commit: + ```console + $ docker compose -f https://github.com/user/repo.git@main up + $ docker compose -f https://github.com/user/repo.git@v1.0.0 up + $ docker compose -f https://github.com/user/repo.git@abc123 up + ``` + + You can also specify a subdirectory within the repository: + ```console + $ docker compose -f https://github.com/user/repo.git#main:path/to/compose.yaml up + ``` + + When using git resources, Compose will clone the repository and use the specified Compose file. You can combine + git resources with local files: + + ```console + $ docker compose -f https://github.com/user/repo.git -f compose.override.yaml up + ``` + + ### Use `-p` to specify a project name + + Each configuration has a project name. Compose sets the project name using + the following mechanisms, in order of precedence: + - The `-p` command line flag + - The `COMPOSE_PROJECT_NAME` environment variable + - The top level `name:` variable from the config file (or the last `name:` + from a series of config files specified using `-f`) + - The `basename` of the project directory containing the config file (or + containing the first config file specified using `-f`) + - The `basename` of the current directory if no config file is specified + Project names must contain only lowercase letters, decimal digits, dashes, + and underscores, and must begin with a lowercase letter or decimal digit. If + the `basename` of the project directory or current directory violates this + constraint, you must use one of the other mechanisms. + + ```console + $ docker compose -p my_project ps -a + NAME SERVICE STATUS PORTS + my_project_demo_1 demo running + + $ docker compose -p my_project logs + demo_1 | PING localhost (127.0.0.1): 56 data bytes + demo_1 | 64 bytes from 127.0.0.1: seq=0 ttl=64 time=0.095 ms + ``` + + ### Use profiles to enable optional services + + Use `--profile` to specify one or more active profiles + Calling `docker compose --profile frontend up` starts the services with the profile `frontend` and services + without any specified profiles. + You can also enable multiple profiles, e.g. with `docker compose --profile frontend --profile debug up` the profiles `frontend` and `debug` is enabled. + + Profiles can also be set by `COMPOSE_PROFILES` environment variable. + + ### Configuring parallelism + + Use `--parallel` to specify the maximum level of parallelism for concurrent engine calls. + Calling `docker compose --parallel 1 pull` pulls the pullable images defined in the Compose file + one at a time. This can also be used to control build concurrency. + + Parallelism can also be set by the `COMPOSE_PARALLEL_LIMIT` environment variable. + + ### Set up environment variables + + You can set environment variables for various docker compose options, including the `-f`, `-p` and `--profiles` flags. + + Setting the `COMPOSE_FILE` environment variable is equivalent to passing the `-f` flag, + `COMPOSE_PROJECT_NAME` environment variable does the same as the `-p` flag, + `COMPOSE_PROFILES` environment variable is equivalent to the `--profiles` flag + and `COMPOSE_PARALLEL_LIMIT` does the same as the `--parallel` flag. + + If flags are explicitly set on the command line, the associated environment variable is ignored. + + Setting the `COMPOSE_IGNORE_ORPHANS` environment variable to `true` stops docker compose from detecting orphaned + containers for the project. + + Setting the `COMPOSE_MENU` environment variable to `false` disables the helper menu when running `docker compose up` + in attached mode. Alternatively, you can also run `docker compose up --menu=false` to disable the helper menu. + + ### Use Dry Run mode to test your command + + Use `--dry-run` flag to test a command without changing your application stack state. + Dry Run mode shows you all the steps Compose applies when executing a command, for example: + ```console + $ docker compose --dry-run up --build -d + [+] Pulling 1/1 + ✔ DRY-RUN MODE - db Pulled 0.9s + [+] Running 10/8 + ✔ DRY-RUN MODE - build service backend 0.0s + ✔ DRY-RUN MODE - ==> ==> writing image dryRun-754a08ddf8bcb1cf22f310f09206dd783d42f7dd 0.0s + ✔ DRY-RUN MODE - ==> ==> naming to nginx-golang-mysql-backend 0.0s + ✔ DRY-RUN MODE - Network nginx-golang-mysql_default Created 0.0s + ✔ DRY-RUN MODE - Container nginx-golang-mysql-db-1 Created 0.0s + ✔ DRY-RUN MODE - Container nginx-golang-mysql-backend-1 Created 0.0s + ✔ DRY-RUN MODE - Container nginx-golang-mysql-proxy-1 Created 0.0s + ✔ DRY-RUN MODE - Container nginx-golang-mysql-db-1 Healthy 0.5s + ✔ DRY-RUN MODE - Container nginx-golang-mysql-backend-1 Started 0.0s + ✔ DRY-RUN MODE - Container nginx-golang-mysql-proxy-1 Started Started + ``` + From the example above, you can see that the first step is to pull the image defined by `db` service, then build the `backend` service. + Next, the containers are created. The `db` service is started, and the `backend` and `proxy` wait until the `db` service is healthy before starting. + + Dry Run mode works with almost all commands. You cannot use Dry Run mode with a command that doesn't change the state of a Compose stack such as `ps`, `ls`, `logs` for example. deprecated: false hidden: false experimental: false diff --git a/_vendor/github.com/docker/compose/v2/docs/reference/docker_compose_alpha.yaml b/_vendor/github.com/docker/compose/v5/docs/reference/docker_compose_alpha.yaml similarity index 89% rename from _vendor/github.com/docker/compose/v2/docs/reference/docker_compose_alpha.yaml rename to _vendor/github.com/docker/compose/v5/docs/reference/docker_compose_alpha.yaml index 807097a387e6..e6b6b6e6b6f7 100644 --- a/_vendor/github.com/docker/compose/v2/docs/reference/docker_compose_alpha.yaml +++ b/_vendor/github.com/docker/compose/v5/docs/reference/docker_compose_alpha.yaml @@ -4,9 +4,11 @@ long: Experimental commands pname: docker compose plink: docker_compose.yaml cname: + - docker compose alpha generate - docker compose alpha publish - docker compose alpha viz clink: + - docker_compose_alpha_generate.yaml - docker_compose_alpha_publish.yaml - docker_compose_alpha_viz.yaml inherited_options: diff --git a/_vendor/github.com/docker/compose/v2/docs/reference/docker_compose_alpha_dry-run.yaml b/_vendor/github.com/docker/compose/v5/docs/reference/docker_compose_alpha_dry-run.yaml similarity index 100% rename from _vendor/github.com/docker/compose/v2/docs/reference/docker_compose_alpha_dry-run.yaml rename to _vendor/github.com/docker/compose/v5/docs/reference/docker_compose_alpha_dry-run.yaml diff --git a/_vendor/github.com/docker/compose/v5/docs/reference/docker_compose_alpha_generate.yaml b/_vendor/github.com/docker/compose/v5/docs/reference/docker_compose_alpha_generate.yaml new file mode 100644 index 000000000000..f31429c2d725 --- /dev/null +++ b/_vendor/github.com/docker/compose/v5/docs/reference/docker_compose_alpha_generate.yaml @@ -0,0 +1,53 @@ +command: docker compose alpha generate +short: EXPERIMENTAL - Generate a Compose file from existing containers +long: EXPERIMENTAL - Generate a Compose file from existing containers +usage: docker compose alpha generate [OPTIONS] [CONTAINERS...] +pname: docker compose alpha +plink: docker_compose_alpha.yaml +options: + - option: format + value_type: string + default_value: yaml + description: 'Format the output.

The deprecation + is not versioned, and applies to all API versions. +* Deprecated: The `is-automated` filter for the `GET /images/search` endpoint. + The `is_automated` field has been deprecated by Docker Hub's search API. + Consequently, searching for `is-automated=true` will yield no results. The + deprecation is not versioned, and applies to all API versions. +* Read-only bind mounts are now made recursively read-only on kernel >= 5.12 + with runtimes which support the feature. + `POST /containers/create`, `GET /containers/{id}/json`, and `GET /containers/json` now supports + `BindOptions.ReadOnlyNonRecursive` and `BindOptions.ReadOnlyForceRecursive` to customize the behavior. +* `POST /containers/create` now accepts a `HealthConfig.StartInterval` to set the + interval for health checks during the start period. +* `GET /info` now includes a `CDISpecDirs` field indicating the configured CDI + specifications directories. The use of the applied setting requires the daemon + to have experimental enabled, and for non-experimental daemons an empty list is + always returned. +* `POST /networks/create` now returns a 400 if the `IPAMConfig` has invalid + values. Note that this change is _unversioned_ and applied to all API + versions on daemon that support version 1.44. +* `POST /networks/create` with a duplicated name now fails systematically. As + such, the `CheckDuplicate` field is now deprecated. Note that this change is + _unversioned_ and applied to all API versions on daemon that support version + 1.44. +* `POST /containers/create` now accepts multiple `EndpointSettings` in + `NetworkingConfig.EndpointSettings`. +* `POST /containers/create` and `POST /networks/{id}/connect` will now catch + validation errors that were previously only returned during `POST /containers/{id}/start`. + These endpoints will also return the full set of validation errors they find, + instead of returning only the first one. + Note that this change is _unversioned_ and applies to all API versions. +* `POST /services/create` and `POST /services/{id}/update` now accept `Seccomp` + and `AppArmor` fields in the `ContainerSpec.Privileges` object. This allows + some configuration of Seccomp and AppArmor in Swarm services. +* A new endpoint-specific `MacAddress` field has been added to `NetworkSettings.EndpointSettings` + on `POST /containers/create`, and to `EndpointConfig` on `POST /networks/{id}/connect`. + The container-wide `MacAddress` field in `Config`, on `POST /containers/create`, is now deprecated. +* The field `Networks` in the `POST /services/create` and `POST /services/{id}/update` + requests is now deprecated. You should instead use the field `TaskTemplate.Networks`. +* The `Container` and `ContainerConfig` fields in the `GET /images/{name}/json` + response are deprecated and will no longer be included in API v1.45. +* `GET /info` now includes `status` properties in `Runtimes`. +* A new field named `DNSNames` and containing all non-fully qualified DNS names + a container takes on a specific network has been added to `GET /containers/{name:.*}/json`. +* The `Aliases` field returned in calls to `GET /containers/{name:.*}/json` in v1.44 and older + versions contains the short container ID. This will change in the next API version, v1.45. + Starting with that API version, this specific value will be removed from the `Aliases` field + such that this field will reflect exactly the values originally submitted to the + `POST /containers/create` endpoint. The newly introduced `DNSNames` should now be used instead. +* The fields `HairpinMode`, `LinkLocalIPv6Address`, `LinkLocalIPv6PrefixLen`, `SecondaryIPAddresses`, + `SecondaryIPv6Addresses` available in `NetworkSettings` when calling `GET /containers/{id}/json` are + deprecated and will be removed in a future release. You should instead look for the default network in + `NetworkSettings.Networks`. +* `GET /images/{id}/json` omits the `Created` field (previously it was `0001-01-01T00:00:00Z`) + if the `Created` field is missing from the image config. + +## v1.43 API changes + +* `POST /containers/create` now accepts `Annotations` as part of `HostConfig`. + Can be used to attach arbitrary metadata to the container, which will also be + passed to the runtime when the container is started. +* `GET /images/json` no longer includes hardcoded `<none>:<none>` and + `<none>@<none>` in `RepoTags` and`RepoDigests` for untagged images. + In such cases, empty arrays will be produced instead. +* The `VirtualSize` field in the `GET /images/{name}/json`, `GET /images/json`, + and `GET /system/df` responses is deprecated and will no longer be included + in API v1.44. Use the `Size` field instead, which contains the same information. +* `GET /info` now includes `no-new-privileges` in the `SecurityOptions` string + list when this option is enabled globally. This change is not versioned, and + affects all API versions if the daemon has this patch. + +## v1.42 API changes + +* Removed the `BuilderSize` field on the `GET /system/df` endpoint. This field + was introduced in API 1.31 as part of an experimental feature, and no longer + used since API 1.40. + Use field `BuildCache` instead to track storage used by the builder component. +* `POST /containers/{id}/stop` and `POST /containers/{id}/restart` now accept a + `signal` query parameter, which allows overriding the container's default stop- + signal. +* `GET /images/json` now accepts query parameter `shared-size`. When set `true`, + images returned will include `SharedSize`, which provides the size on disk shared + with other images present on the system. +* `GET /system/df` now accepts query parameter `type`. When set, + computes and returns data only for the specified object type. + The parameter can be specified multiple times to select several object types. + Supported values are: `container`, `image`, `volume`, `build-cache`. +* `GET /system/df` can now be used concurrently. If a request is made while a + previous request is still being processed, the request will receive the result + of the already running calculation, once completed. Previously, an error + (`a disk usage operation is already running`) would be returned in this + situation. This change is not versioned, and affects all API versions if the + daemon has this patch. +* The `POST /images/create` now supports both the operating system and architecture + that is passed through the `platform` query parameter when using the `fromSrc` + option to import an image from an archive. Previously, only the operating system + was used and the architecture was ignored. If no `platform` option is set, the + host's operating system and architecture as used as default. This change is not + versioned, and affects all API versions if the daemon has this patch. +* The `POST /containers/{id}/wait` endpoint now returns a `400` status code if an + invalid `condition` is provided (on API 1.30 and up). +* Removed the `KernelMemory` field from the `POST /containers/create` and + `POST /containers/{id}/update` endpoints, any value it is set to will be ignored + on API version `v1.42` and up. Older API versions still accept this field, but + may take no effect, depending on the kernel version and OCI runtime in use. +* `GET /containers/{id}/json` now omits the `KernelMemory` and `KernelMemoryTCP` + if they are not set. +* `GET /info` now omits the `KernelMemory` and `KernelMemoryTCP` if they are not + supported by the host or host's configuration (if cgroups v2 are in use). +* `GET /_ping` and `HEAD /_ping` now return `Builder-Version` by default. + This header contains the default builder to use, and is a recommendation as + advertised by the daemon. However, it is up to the client to choose which builder + to use. + + The default value on Linux is version "2" (BuildKit), but the daemon can be + configured to recommend version "1" (classic Builder). Windows does not yet + support BuildKit for native Windows images, and uses "1" (classic builder) as + a default. + + This change is not versioned, and affects all API versions if the daemon has + this patch. +* `GET /_ping` and `HEAD /_ping` now return a `Swarm` header, which allows a + client to detect if Swarm is enabled on the daemon, without having to call + additional endpoints. + This change is not versioned, and affects all API versions if the daemon has + this patch. Clients must consider this header "optional", and fall back to + using other endpoints to get this information if the header is not present. + + The `Swarm` header can contain one of the following values: + + - "inactive" + - "pending" + - "error" + - "locked" + - "active/worker" + - "active/manager" +* `POST /containers/create` for Windows containers now accepts a new syntax in + `HostConfig.Resources.Devices.PathOnHost`. As well as the existing `class/<GUID>` + syntax, `<IDType>://<ID>` is now recognised. Support for specific `<IDType>` values + depends on the underlying implementation and Windows version. This change is not + versioned, and affects all API versions if the daemon has this patch. +* `GET /containers/{id}/attach`, `GET /exec/{id}/start`, `GET /containers/{id}/logs` + `GET /services/{id}/logs` and `GET /tasks/{id}/logs` now set Content-Type header + to `application/vnd.docker.multiplexed-stream` when a multiplexed stdout/stderr + stream is sent to client, `application/vnd.docker.raw-stream` otherwise. +* `POST /volumes/create` now accepts a new `ClusterVolumeSpec` to create a cluster + volume (CNI). This option can only be used if the daemon is a Swarm manager. + The Volume response on creation now also can contain a `ClusterVolume` field + with information about the created volume. +* The `BuildCache.Parent` field, as returned by `GET /system/df` is deprecated + and is now omitted. API versions before v1.42 continue to include this field. +* `GET /system/df` now includes a new `Parents` field, for "build-cache" records, + which contains a list of parent IDs for the build-cache record. +* Volume information returned by `GET /volumes/{name}`, `GET /volumes` and + `GET /system/df` can now contain a `ClusterVolume` if the volume is a cluster + volume (requires the daemon to be a Swarm manager). +* The `Volume` type, as returned by `Added new `ClusterVolume` fields +* Added a new `PUT /volumes{name}` endpoint to update cluster volumes (CNI). + Cluster volumes are only supported if the daemon is a Swarm manager. +* `GET /containers/{name}/attach/ws` endpoint now accepts `stdin`, `stdout` and + `stderr` query parameters to only attach to configured streams. + + NOTE: These parameters were documented before in older API versions, but not + actually supported. API versions before v1.42 continue to ignore these parameters + and default to attaching to all streams. To preserve the pre-v1.42 behavior, + set all three query parameters (`?stdin=1,stdout=1,stderr=1`). +* `POST /containers/create` on Linux now respects the `HostConfig.ConsoleSize` property. + Container is immediately created with the desired terminal size and clients no longer + need to set the desired size on their own. +* `POST /containers/create` allow to set `CreateMountpoint` for host path to be + created if missing. This brings parity with `Binds` +* `POST /containers/create` rejects request if BindOptions|VolumeOptions|TmpfsOptions + is set with a non-matching mount Type. +* `POST /containers/{id}/exec` now accepts an optional `ConsoleSize` parameter. + It allows to set the console size of the executed process immediately when it's created. +* `POST /volumes/prune` will now only prune "anonymous" volumes (volumes which were not given a name) by default. A new filter parameter `all` can be set to a truth-y value (`true`, `1`) to get the old behavior. + +## v1.41 API changes + +* `GET /events` now returns `prune` events after pruning resources have completed. + Prune events are returned for `container`, `network`, `volume`, `image`, and + `builder`, and have a `reclaimed` attribute, indicating the amount of space + reclaimed (in bytes). +* `GET /info` now returns a `CgroupVersion` field, containing the cgroup version. +* `GET /info` now returns a `DefaultAddressPools` field, containing a list of + custom default address pools for local networks, which can be specified in the + `daemon.json` file or `--default-address-pool` dockerd option. +* `POST /services/create` and `POST /services/{id}/update` now supports `BindOptions.NonRecursive`. +* The `ClusterStore` and `ClusterAdvertise` fields in `GET /info` are deprecated + and are now omitted if they contain an empty value. This change is not versioned, + and affects all API versions if the daemon has this patch. +* The `filter` (singular) query parameter, which was deprecated in favor of the + `filters` option in Docker 1.13, has now been removed from the `GET /images/json` + endpoint. The parameter remains available when using API version 1.40 or below. +* `GET /services` now returns `CapAdd` and `CapDrop` as part of the `ContainerSpec`. +* `GET /services/{id}` now returns `CapAdd` and `CapDrop` as part of the `ContainerSpec`. +* `POST /services/create` now accepts `CapAdd` and `CapDrop` as part of the `ContainerSpec`. +* `POST /services/{id}/update` now accepts `CapAdd` and `CapDrop` as part of the `ContainerSpec`. +* `GET /tasks` now returns `CapAdd` and `CapDrop` as part of the `ContainerSpec`. +* `GET /tasks/{id}` now returns `CapAdd` and `CapDrop` as part of the `ContainerSpec`. +* `GET /services` now returns `Pids` in `TaskTemplate.Resources.Limits`. +* `GET /services/{id}` now returns `Pids` in `TaskTemplate.Resources.Limits`. +* `POST /services/create` now accepts `Pids` in `TaskTemplate.Resources.Limits`. +* `POST /services/{id}/update` now accepts `Pids` in `TaskTemplate.Resources.Limits` + to limit the maximum number of PIDs. +* `GET /tasks` now returns `Pids` in `TaskTemplate.Resources.Limits`. +* `GET /tasks/{id}` now returns `Pids` in `TaskTemplate.Resources.Limits`. +* `POST /containers/create` now accepts a `platform` query parameter in the format + `os[/arch[/variant]]`. + + When set, the daemon checks if the requested image is present in the local image + cache with the given OS and Architecture, and otherwise returns a `404` status. + + If the option is _not_ set, the host's native OS and Architecture are used to + look up the image in the image cache. However, if no platform is passed and the + given image _does_ exist in the local image cache, but its OS or architecture + do not match, the container is created with the available image, and a warning + is added to the `Warnings` field in the response, for example; + + WARNING: The requested image's platform (linux/arm64/v8) does not + match the detected host platform (linux/amd64) and no + specific platform was requested + +* `POST /containers/create` on Linux now accepts the `HostConfig.CgroupnsMode` property. + Set the property to `host` to create the container in the daemon's cgroup namespace, or + `private` to create the container in its own private cgroup namespace. The per-daemon + default is `host`, and can be changed by using the`CgroupNamespaceMode` daemon configuration + parameter. +* `GET /info` now returns an `OSVersion` field, containing the operating system's + version. This change is not versioned, and affects all API versions if the daemon + has this patch. +* `GET /info` no longer returns the `SystemStatus` field if it does not have a + value set. This change is not versioned, and affects all API versions if the + daemon has this patch. +* `GET /services` now accepts query parameter `status`. When set `true`, + services returned will include `ServiceStatus`, which provides Desired, + Running, and Completed task counts for the service. +* `GET /services` may now include `ReplicatedJob` or `GlobalJob` as the `Mode` + in a `ServiceSpec`. +* `GET /services/{id}` may now include `ReplicatedJob` or `GlobalJob` as the + `Mode` in a `ServiceSpec`. +* `POST /services/create` now accepts `ReplicatedJob or `GlobalJob` as the `Mode` + in the `ServiceSpec. +* `POST /services/{id}/update` accepts updating the fields of the + `ReplicatedJob` object in the `ServiceSpec.Mode`. The service mode still + cannot be changed, however. +* `GET /services` now includes `JobStatus` on Services with mode + `ReplicatedJob` or `GlobalJob`. +* `GET /services/{id}` now includes `JobStatus` on Services with mode + `ReplicatedJob` or `GlobalJob`. +* `GET /tasks` now includes `JobIteration` on Tasks spawned from a job-mode + service. +* `GET /tasks/{id}` now includes `JobIteration` on the task if spawned from a + job-mode service. +* `GET /containers/{id}/stats` now accepts a query param (`one-shot`) which, when used with `stream=false` fetches a + single set of stats instead of waiting for two collection cycles to have 2 CPU stats over a 1 second period. +* The `KernelMemory` field in `HostConfig.Resources` is now deprecated. +* The `KernelMemory` field in `Info` is now deprecated. +* `GET /services` now returns `Ulimits` as part of `ContainerSpec`. +* `GET /services/{id}` now returns `Ulimits` as part of `ContainerSpec`. +* `POST /services/create` now accepts `Ulimits` as part of `ContainerSpec`. +* `POST /services/{id}/update` now accepts `Ulimits` as part of `ContainerSpec`. + +## v1.40 API changes + +* The `/_ping` endpoint can now be accessed both using `GET` or `HEAD` requests. + when accessed using a `HEAD` request, all headers are returned, but the body + is empty (`Content-Length: 0`). This change is not versioned, and affects all + API versions if the daemon has this patch. Clients are recommended to try + using `HEAD`, but fallback to `GET` if the `HEAD` requests fails. +* `GET /_ping` and `HEAD /_ping` now set `Cache-Control` and `Pragma` headers to + prevent the result from being cached. This change is not versioned, and affects + all API versions if the daemon has this patch. +* `GET /services` now returns `Sysctls` as part of the `ContainerSpec`. +* `GET /services/{id}` now returns `Sysctls` as part of the `ContainerSpec`. +* `POST /services/create` now accepts `Sysctls` as part of the `ContainerSpec`. +* `POST /services/{id}/update` now accepts `Sysctls` as part of the `ContainerSpec`. +* `POST /services/create` now accepts `Config` as part of `ContainerSpec.Privileges.CredentialSpec`. +* `POST /services/{id}/update` now accepts `Config` as part of `ContainerSpec.Privileges.CredentialSpec`. +* `POST /services/create` now includes `Runtime` as an option in `ContainerSpec.Configs` +* `POST /services/{id}/update` now includes `Runtime` as an option in `ContainerSpec.Configs` +* `GET /tasks` now returns `Sysctls` as part of the `ContainerSpec`. +* `GET /tasks/{id}` now returns `Sysctls` as part of the `ContainerSpec`. +* `GET /networks` now supports a `dangling` filter type.

When + set to `false` (or `0`), only networks that are in use by one or more containers + are returned. +* `GET /nodes` now supports a filter type `node.label` filter to filter nodes based + on the node.label. The format of the label filter is `node.label=<key>`/`node.label=<key>=<value>` + to return those with the specified labels, or `node.label!=<key>`/`node.label!=<key>=<value>` + to return those without the specified labels. +* `POST /containers/create` now accepts a `fluentd-async` option in `HostConfig.LogConfig.Config` + when using the Fluentd logging driver. This option deprecates the `fluentd-async-connect` + option, which remains functional, but will be removed in a future release. Users + are encouraged to use the `fluentd-async` option going forward. This change is + not versioned, and affects all API versions if the daemon has this patch. +* `POST /containers/create` now accepts a `fluentd-request-ack` option in + `HostConfig.LogConfig.Config` when using the Fluentd logging driver. If enabled, + the Fluentd logging driver sends the chunk option with a unique ID. The server + will respond with an acknowledgement.

Going + forward, the information from the `Components` section is preferred over their + top-level counterparts. + + +## v1.34 API changes + +* `POST /containers/(name)/wait?condition=removed` now also also returns + in case of container removal failure. A pointer to a structure named + `Error` added to the response JSON in order to indicate a failure. + If `Error` is `null`, container removal has succeeded, otherwise + the test of an error message indicating why container removal has failed + is available from `Error.Message` field. + +## v1.33 API changes + +* `GET /events` now supports filtering 4 more kinds of events: `config`, `node`, +`secret` and `service`. + +## v1.32 API changes + +* `POST /images/create` now accepts a `platform` parameter in the form of `os[/arch[/variant]]`. +* `POST /containers/create` now accepts additional values for the + `HostConfig.IpcMode` property.

The stream consists of a series of frames, each + containing a header and a payload. + + The header contains the information which the stream writes (`stdout` or + `stderr`). It also contains the size of the associated frame encoded in + the last four bytes (`uint32`). + + It is encoded on the first eight bytes like this: + + ```go + header := [8]byte{STREAM_TYPE, 0, 0, 0, SIZE1, SIZE2, SIZE3, SIZE4} + ``` + + `STREAM_TYPE` can be: + + - 0: `stdin` (is written on `stdout`) + - 1: `stdout` + - 2: `stderr` + + `SIZE1, SIZE2, SIZE3, SIZE4` are the four bytes of the `uint32` size + encoded as big endian. + + Following the header is the payload, which is the specified number of + bytes of `STREAM_TYPE`. + + The simplest way to implement this protocol is the following: + + 1. Read 8 bytes. + 2. Choose `stdout` or `stderr` depending on the first byte. + 3. Extract the frame size from the last four bytes. + 4. Read the extracted size and output it on the correct output. + 5. Goto 1. + + ### Stream format when using a TTY + + When the TTY setting is enabled in [`POST /containers/create`](#operation/ContainerCreate), + the stream is not multiplexed.

It is the API the + Docker client uses to communicate with the Engine, so everything the Docker + client can do can be done with the API. + + Most of the client's commands map directly to API endpoints (e.g. `docker ps` + is `GET /containers/json`). The notable exception is running containers, + which consists of several API calls. + + # Errors + + The API uses standard HTTP status codes to indicate the success or failure + of the API call. The body of the response will be JSON in the following + format: + + ``` + { + "message": "page not found" + } + ``` + + # Versioning + + The API is usually changed in each release, so API calls are versioned to + ensure that clients don't break. To lock to a specific version of the API, + you prefix the URL with its version, for example, call `/v1.30/info` to use + the v1.30 version of the `/info` endpoint. If the API version specified in + the URL is not supported by the daemon, a HTTP `400 Bad Request` error message + is returned. + + If you omit the version-prefix, the current version of the API (v1.48) is used. + For example, calling `/info` is the same as calling `/v1.48/info`. Using the + API without a version-prefix is deprecated and will be removed in a future release. + + Engine releases in the near future should support this version of the API, + so your client will continue to work even if it is talking to a newer Engine. + + The API uses an open schema model, which means the server may add extra properties + to responses. Likewise, the server will ignore any extra query parameters and + request body properties. When you write clients, you need to ignore additional + properties in responses to ensure they do not break when talking to newer + daemons. + + + # Authentication + + Authentication for registries is handled client side. The client has to send + authentication details to various endpoints that need to communicate with + registries, such as `POST /images/(name)/push`. These are sent as + `X-Registry-Auth` header as a [base64url encoded](https://tools.ietf.org/html/rfc4648#section-5) + (JSON) string with the following structure: + + ``` + { + "username": "string", + "password": "string", + "serveraddress": "string" + } + ``` + + The `serveraddress` is a domain/IP without a protocol. Throughout this + structure, double quotes are required. + + If you have already got an identity token from the [`/auth` endpoint](#operation/SystemAuth), + you can just pass this instead of credentials: + + ``` + { + "identitytoken": "9cbaf023786cd7..." + } + ``` + +# The tags on paths define the menu sections in the ReDoc documentation, so +# the usage of tags must make sense for that: +# - They should be singular, not plural. +# - There should not be too many tags, or the menu becomes unwieldy. For +# example, it is preferable to add a path to the "System" tag instead of +# creating a tag with a single path in it. +# - The order of tags in this list defines the order in the menu. +tags: + # Primary objects + - name: "Container" + x-displayName: "Containers" + description: | + Create and manage containers. + - name: "Image" + x-displayName: "Images" + - name: "Network" + x-displayName: "Networks" + description: | + Networks are user-defined networks that containers can be attached to. + See the [networking documentation](https://docs.docker.com/network/) + for more information. + - name: "Volume" + x-displayName: "Volumes" + description: | + Create and manage persistent storage that can be attached to containers. + - name: "Exec" + x-displayName: "Exec" + description: | + Run new commands inside running containers.

It is the API the + Docker client uses to communicate with the Engine, so everything the Docker + client can do can be done with the API. + + Most of the client's commands map directly to API endpoints (e.g. `docker ps` + is `GET /containers/json`). The notable exception is running containers, + which consists of several API calls. + + # Errors + + The API uses standard HTTP status codes to indicate the success or failure + of the API call. The body of the response will be JSON in the following + format: + + ``` + { + "message": "page not found" + } + ``` + + # Versioning + + The API is usually changed in each release, so API calls are versioned to + ensure that clients don't break. To lock to a specific version of the API, + you prefix the URL with its version, for example, call `/v1.30/info` to use + the v1.30 version of the `/info` endpoint. If the API version specified in + the URL is not supported by the daemon, a HTTP `400 Bad Request` error message + is returned. + + If you omit the version-prefix, the current version of the API (v1.49) is used. + For example, calling `/info` is the same as calling `/v1.49/info`. Using the + API without a version-prefix is deprecated and will be removed in a future release. + + Engine releases in the near future should support this version of the API, + so your client will continue to work even if it is talking to a newer Engine. + + The API uses an open schema model, which means the server may add extra properties + to responses. Likewise, the server will ignore any extra query parameters and + request body properties. When you write clients, you need to ignore additional + properties in responses to ensure they do not break when talking to newer + daemons. + + + # Authentication + + Authentication for registries is handled client side. The client has to send + authentication details to various endpoints that need to communicate with + registries, such as `POST /images/(name)/push`. These are sent as + `X-Registry-Auth` header as a [base64url encoded](https://tools.ietf.org/html/rfc4648#section-5) + (JSON) string with the following structure: + + ``` + { + "username": "string", + "password": "string", + "serveraddress": "string" + } + ``` + + The `serveraddress` is a domain/IP without a protocol.

The stream consists of a series of frames, each + containing a header and a payload. + + The header contains the information which the stream writes (`stdout` or + `stderr`). It also contains the size of the associated frame encoded in + the last four bytes (`uint32`). + + It is encoded on the first eight bytes like this: + + ```go + header := [8]byte{STREAM_TYPE, 0, 0, 0, SIZE1, SIZE2, SIZE3, SIZE4} + ``` + + `STREAM_TYPE` can be: + + - 0: `stdin` (is written on `stdout`) + - 1: `stdout` + - 2: `stderr` + + `SIZE1, SIZE2, SIZE3, SIZE4` are the four bytes of the `uint32` size + encoded as big endian. + + Following the header is the payload, which is the specified number of + bytes of `STREAM_TYPE`. + + The simplest way to implement this protocol is the following: + + 1.

It is the API the + Docker client uses to communicate with the Engine, so everything the Docker + client can do can be done with the API. + + Most of the client's commands map directly to API endpoints (e.g. `docker ps` + is `GET /containers/json`). The notable exception is running containers, + which consists of several API calls. + + # Errors + + The API uses standard HTTP status codes to indicate the success or failure + of the API call. The body of the response will be JSON in the following + format: + + ``` + { + "message": "page not found" + } + ``` + + # Versioning + + The API is usually changed in each release, so API calls are versioned to + ensure that clients don't break. To lock to a specific version of the API, + you prefix the URL with its version, for example, call `/v1.30/info` to use + the v1.30 version of the `/info` endpoint. If the API version specified in + the URL is not supported by the daemon, a HTTP `400 Bad Request` error message + is returned. + + If you omit the version-prefix, the current version of the API (v1.50) is used. + For example, calling `/info` is the same as calling `/v1.50/info`. Using the + API without a version-prefix is deprecated and will be removed in a future release. + + Engine releases in the near future should support this version of the API, + so your client will continue to work even if it is talking to a newer Engine. + + The API uses an open schema model, which means the server may add extra properties + to responses. Likewise, the server will ignore any extra query parameters and + request body properties. When you write clients, you need to ignore additional + properties in responses to ensure they do not break when talking to newer + daemons. + + + # Authentication + + Authentication for registries is handled client side. The client has to send + authentication details to various endpoints that need to communicate with + registries, such as `POST /images/(name)/push`. These are sent as + `X-Registry-Auth` header as a [base64url encoded](https://tools.ietf.org/html/rfc4648#section-5) + (JSON) string with the following structure: + + ``` + { + "username": "string", + "password": "string", + "serveraddress": "string" + } + ``` + + The `serveraddress` is a domain/IP without a protocol. Throughout this + structure, double quotes are required. + + If you have already got an identity token from the [`/auth` endpoint](#operation/SystemAuth), + you can just pass this instead of credentials: + + ``` + { + "identitytoken": "9cbaf023786cd7..." + } + ``` + +# The tags on paths define the menu sections in the ReDoc documentation, so +# the usage of tags must make sense for that: +# - They should be singular, not plural. +# - There should not be too many tags, or the menu becomes unwieldy. For +# example, it is preferable to add a path to the "System" tag instead of +# creating a tag with a single path in it. +# - The order of tags in this list defines the order in the menu. +tags: + # Primary objects + - name: "Container" + x-displayName: "Containers" + description: | + Create and manage containers. + - name: "Image" + x-displayName: "Images" + - name: "Network" + x-displayName: "Networks" + description: | + Networks are user-defined networks that containers can be attached to. + See the [networking documentation](https://docs.docker.com/network/) + for more information. + - name: "Volume" + x-displayName: "Volumes" + description: | + Create and manage persistent storage that can be attached to containers. + - name: "Exec" + x-displayName: "Exec" + description: | + Run new commands inside running containers.

It is the API the + Docker client uses to communicate with the Engine, so everything the Docker + client can do can be done with the API. + + Most of the client's commands map directly to API endpoints (e.g. `docker ps` + is `GET /containers/json`). The notable exception is running containers, + which consists of several API calls. + + # Errors + + The API uses standard HTTP status codes to indicate the success or failure + of the API call. The body of the response will be JSON in the following + format: + + ``` + { + "message": "page not found" + } + ``` + + # Versioning + + The API is usually changed in each release, so API calls are versioned to + ensure that clients don't break. To lock to a specific version of the API, + you prefix the URL with its version, for example, call `/v1.30/info` to use + the v1.30 version of the `/info` endpoint. If the API version specified in + the URL is not supported by the daemon, a HTTP `400 Bad Request` error message + is returned. + + If you omit the version-prefix, the current version of the API (v1.50) is used. + For example, calling `/info` is the same as calling `/v1.51/info`. Using the + API without a version-prefix is deprecated and will be removed in a future release. + + Engine releases in the near future should support this version of the API, + so your client will continue to work even if it is talking to a newer Engine. + + The API uses an open schema model, which means the server may add extra properties + to responses. Likewise, the server will ignore any extra query parameters and + request body properties. When you write clients, you need to ignore additional + properties in responses to ensure they do not break when talking to newer + daemons. + + + # Authentication + + Authentication for registries is handled client side. The client has to send + authentication details to various endpoints that need to communicate with + registries, such as `POST /images/(name)/push`. These are sent as + `X-Registry-Auth` header as a [base64url encoded](https://tools.ietf.org/html/rfc4648#section-5) + (JSON) string with the following structure: + + ``` + { + "username": "string", + "password": "string", + "serveraddress": "string" + } + ``` + + The `serveraddress` is a domain/IP without a protocol.

The stream consists of a series of frames, each + containing a header and a payload. + + The header contains the information which the stream writes (`stdout` or + `stderr`). It also contains the size of the associated frame encoded in + the last four bytes (`uint32`). + + It is encoded on the first eight bytes like this: + + ```go + header := [8]byte{STREAM_TYPE, 0, 0, 0, SIZE1, SIZE2, SIZE3, SIZE4} + ``` + + `STREAM_TYPE` can be: + + - 0: `stdin` (is written on `stdout`) + - 1: `stdout` + - 2: `stderr` + + `SIZE1, SIZE2, SIZE3, SIZE4` are the four bytes of the `uint32` size + encoded as big endian. + + Following the header is the payload, which is the specified number of + bytes of `STREAM_TYPE`. + + The simplest way to implement this protocol is the following: + + 1.

It is the API the + Docker client uses to communicate with the Engine, so everything the Docker + client can do can be done with the API. + + Most of the client's commands map directly to API endpoints (e.g. `docker ps` + is `GET /containers/json`). The notable exception is running containers, + which consists of several API calls. + + # Errors + + The API uses standard HTTP status codes to indicate the success or failure + of the API call. The body of the response will be JSON in the following + format: + + ``` + { + "message": "page not found" + } + ``` + + # Versioning + + The API is usually changed in each release, so API calls are versioned to + ensure that clients don't break. To lock to a specific version of the API, + you prefix the URL with its version, for example, call `/v1.30/info` to use + the v1.30 version of the `/info` endpoint. If the API version specified in + the URL is not supported by the daemon, a HTTP `400 Bad Request` error message + is returned. + + If you omit the version-prefix, the current version of the API (v1.50) is used. + For example, calling `/info` is the same as calling `/v1.52/info`. Using the + API without a version-prefix is deprecated and will be removed in a future release. + + Engine releases in the near future should support this version of the API, + so your client will continue to work even if it is talking to a newer Engine. + + The API uses an open schema model, which means the server may add extra properties + to responses. Likewise, the server will ignore any extra query parameters and + request body properties.

It is the API the + Docker client uses to communicate with the Engine, so everything the Docker + client can do can be done with the API. + + Most of the client's commands map directly to API endpoints (e.g. `docker ps` + is `GET /containers/json`). The notable exception is running containers, + which consists of several API calls. + + # Errors + + The API uses standard HTTP status codes to indicate the success or failure + of the API call. The body of the response will be JSON in the following + format: + + ``` + { + "message": "page not found" + } + ``` + + # Versioning + + The API is usually changed in each release, so API calls are versioned to + ensure that clients don't break. To lock to a specific version of the API, + you prefix the URL with its version, for example, call `/v1.30/info` to use + the v1.30 version of the `/info` endpoint. If the API version specified in + the URL is not supported by the daemon, a HTTP `400 Bad Request` error message + is returned. + + If you omit the version-prefix, the current version of the API (v1.50) is used. + For example, calling `/info` is the same as calling `/v1.52/info`. Using the + API without a version-prefix is deprecated and will be removed in a future release. + + Engine releases in the near future should support this version of the API, + so your client will continue to work even if it is talking to a newer Engine. + + The API uses an open schema model, which means the server may add extra properties + to responses. Likewise, the server will ignore any extra query parameters and + request body properties. When you write clients, you need to ignore additional + properties in responses to ensure they do not break when talking to newer + daemons. + + + # Authentication + + Authentication for registries is handled client side. The client has to send + authentication details to various endpoints that need to communicate with + registries, such as `POST /images/(name)/push`. These are sent as + `X-Registry-Auth` header as a [base64url encoded](https://tools.ietf.org/html/rfc4648#section-5) + (JSON) string with the following structure: + + ``` + { + "username": "string", + "password": "string", + "serveraddress": "string" + } + ``` + + The `serveraddress` is a domain/IP without a protocol.

It also contains the size of the associated frame encoded in + the last four bytes (`uint32`). + + It is encoded on the first eight bytes like this: + + ```go + header := [8]byte{STREAM_TYPE, 0, 0, 0, SIZE1, SIZE2, SIZE3, SIZE4} + ``` + + `STREAM_TYPE` can be: + + - 0: `stdin` (is written on `stdout`) + - 1: `stdout` + - 2: `stderr` + + `SIZE1, SIZE2, SIZE3, SIZE4` are the four bytes of the `uint32` size + encoded as big endian. + + Following the header is the payload, which is the specified number of + bytes of `STREAM_TYPE`. + + The simplest way to implement this protocol is the following: + + 1.

The value is a comma separated list of sysctl assignments, the - interface name must be "IFNAME". For example, to set - `net.ipv4.config.eth0.log_martians=1`, use - `net.ipv4.config.IFNAME.log_martians=1`. In API versions up-to 1.46, top level - `--sysctl` settings for `eth0` will be migrated to `DriverOpts` when possible. - This automatic migration will be removed for API versions 1.47 and greater. -* `GET /containers/json` now returns the annotations of containers. -* `POST /images/{name}/push` now supports a `platform` parameter (JSON encoded - OCI Platform type) that allows selecting a specific platform manifest from - the multi-platform image. -* `POST /containers/create` now takes `Options` as part of `HostConfig.Mounts.TmpfsOptions` to set options for tmpfs mounts. -* `POST /services/create` now takes `Options` as part of `ContainerSpec.Mounts.TmpfsOptions`, to set options for tmpfs mounts. -* `GET /events` now supports image `create` event that is emitted when a new - image is built regardless if it was tagged or not. - -### Deprecated Config fields in `GET /images/{name}/json` response - -The `Config` field returned by this endpoint (used for "image inspect") returns -additional fields that are not part of the image's configuration and not part of -the [Docker Image Spec] and the [OCI Image Spec]. - -These additional fields are included in the response, due to an -implementation detail, where the [api/types.ImageInspec] type used -for the response is using the [container.Config] type. - -The [container.Config] type is a superset of the image config, and while the -image's Config is used as a _template_ for containers created from the image, -the additional fields are set at runtime (from options passed when creating -the container) and not taken from the image Config. - -These fields are never set (and always return the default value for the type), -but are not omitted in the response when left empty. As these fields were not -intended to be part of the image configuration response, they are deprecated, -and will be removed from the API. - -The following fields are currently included in the API response, but -are not part of the underlying image's Config, and deprecated: - -- `Hostname` -- `Domainname` -- `AttachStdin` -- `AttachStdout` -- `AttachStderr` -- `Tty` -- `OpenStdin` -- `StdinOnce` -- `Image` -- `NetworkDisabled` (already omitted unless set) -- `MacAddress` (already omitted unless set) -- `StopTimeout` (already omitted unless set) - -[Docker image spec]: https://github.com/moby/docker-image-spec/blob/v1.3.1/specs-go/v1/image.go#L19-L32 -[OCI Image Spec]: https://github.com/opencontainers/image-spec/blob/v1.1.0/specs-go/v1/config.go#L24-L62 -[api/types.ImageInspec]: https://github.com/moby/moby/blob/v26.1.4/api/types/types.go#L87-L104 -[container.Config]: https://github.com/moby/moby/blob/v26.1.4/api/types/container/config.go#L47-L82 - -* `POST /services/create` and `POST /services/{id}/update` now support OomScoreAdj - -## v1.45 API changes - -[Docker Engine API v1.45](https://docs.docker.com/engine/api/v1.45/) documentation - -* `POST /containers/create` now supports `VolumeOptions.Subpath` which allows a - subpath of a named volume to be mounted. -* `POST /images/search` will always assume a `false` value for the `is-automated` - field. Consequently, searching for `is-automated=true` will yield no results, - while `is-automated=false` will be a no-op. -* `GET /images/{name}/json` no longer includes the `Container` and - `ContainerConfig` fields. To access image configuration, use `Config` field - instead. -* The `Aliases` field returned in calls to `GET /containers/{name:.*}/json` no - longer contains the short container ID, but instead will reflect exactly the - values originally submitted to the `POST /containers/create` endpoint. The - newly introduced `DNSNames` should now be used instead when short container - IDs are needed. - -## v1.44 API changes - -[Docker Engine API v1.44](https://docs.docker.com/engine/api/v1.44/) documentation - -* GET `/images/json` now accepts an `until` filter. This accepts a timestamp and - lists all images created before it. The `<timestamp>` can be Unix timestamps, - date formatted timestamps, or Go duration strings (e.g. `10m`, `1h30m`) - computed relative to the daemon machine’s time. This change is not versioned, - and affects all API versions if the daemon has this patch. -* The `VirtualSize` field in the `GET /images/{name}/json`, `GET /images/json`, - and `GET /system/df` responses is now omitted. Use the `Size` field instead, - which contains the same information. -* Deprecated: The `is_automated` field in the `GET /images/search` response has - been deprecated and will always be set to false in the future because Docker - Hub is deprecating the `is_automated` field in its search API. The deprecation - is not versioned, and applies to all API versions. -* Deprecated: The `is-automated` filter for the `GET /images/search` endpoint. - The `is_automated` field has been deprecated by Docker Hub's search API. - Consequently, searching for `is-automated=true` will yield no results. The - deprecation is not versioned, and applies to all API versions. -* Read-only bind mounts are now made recursively read-only on kernel >= 5.12 - with runtimes which support the feature. - `POST /containers/create`, `GET /containers/{id}/json`, and `GET /containers/json` now supports - `BindOptions.ReadOnlyNonRecursive` and `BindOptions.ReadOnlyForceRecursive` to customize the behavior. -* `POST /containers/create` now accepts a `HealthConfig.StartInterval` to set the - interval for health checks during the start period. -* `GET /info` now includes a `CDISpecDirs` field indicating the configured CDI - specifications directories. The use of the applied setting requires the daemon - to have expermental enabled, and for non-experimental daemons an empty list is - always returned. -* `POST /networks/create` now returns a 400 if the `IPAMConfig` has invalid - values. Note that this change is _unversioned_ and applied to all API - versions on daemon that support version 1.44. -* `POST /networks/create` with a duplicated name now fails systematically. As - such, the `CheckDuplicate` field is now deprecated. Note that this change is - _unversioned_ and applied to all API versions on daemon that support version - 1.44. -* `POST /containers/create` now accepts multiple `EndpointSettings` in - `NetworkingConfig.EndpointSettings`. -* `POST /containers/create` and `POST /networks/{id}/connect` will now catch - validation errors that were previously only returned during `POST /containers/{id}/start`. - These endpoints will also return the full set of validation errors they find, - instead of returning only the first one. - Note that this change is _unversioned_ and applies to all API versions. -* `POST /services/create` and `POST /services/{id}/update` now accept `Seccomp` - and `AppArmor` fields in the `ContainerSpec.Privileges` object. This allows - some configuration of Seccomp and AppArmor in Swarm services. -* A new endpoint-specific `MacAddress` field has been added to `NetworkSettings.EndpointSettings` - on `POST /containers/create`, and to `EndpointConfig` on `POST /networks/{id}/connect`. - The container-wide `MacAddress` field in `Config`, on `POST /containers/create`, is now deprecated. -* The field `Networks` in the `POST /services/create` and `POST /services/{id}/update` - requests is now deprecated. You should instead use the field `TaskTemplate.Networks`. -* The `Container` and `ContainerConfig` fields in the `GET /images/{name}/json` - response are deprecated and will no longer be included in API v1.45. -* `GET /info` now includes `status` properties in `Runtimes`. -* A new field named `DNSNames` and containing all non-fully qualified DNS names - a container takes on a specific network has been added to `GET /containers/{name:.*}/json`. -* The `Aliases` field returned in calls to `GET /containers/{name:.*}/json` in v1.44 and older - versions contains the short container ID. This will change in the next API version, v1.45. - Starting with that API version, this specific value will be removed from the `Aliases` field - such that this field will reflect exactly the values originally submitted to the - `POST /containers/create` endpoint. The newly introduced `DNSNames` should now be used instead. -* The fields `HairpinMode`, `LinkLocalIPv6Address`, `LinkLocalIPv6PrefixLen`, `SecondaryIPAddresses`, - `SecondaryIPv6Addresses` available in `NetworkSettings` when calling `GET /containers/{id}/json` are - deprecated and will be removed in a future release. You should instead look for the default network in - `NetworkSettings.Networks`. -* `GET /images/{id}/json` omits the `Created` field (previously it was `0001-01-01T00:00:00Z`) - if the `Created` field is missing from the image config. - -## v1.43 API changes - -[Docker Engine API v1.43](https://docs.docker.com/engine/api/v1.43/) documentation - -* `POST /containers/create` now accepts `Annotations` as part of `HostConfig`. - Can be used to attach arbitrary metadata to the container, which will also be - passed to the runtime when the container is started. -* `GET /images/json` no longer includes hardcoded `<none>:<none>` and - `<none>@<none>` in `RepoTags` and`RepoDigests` for untagged images. - In such cases, empty arrays will be produced instead. -* The `VirtualSize` field in the `GET /images/{name}/json`, `GET /images/json`, - and `GET /system/df` responses is deprecated and will no longer be included - in API v1.44. Use the `Size` field instead, which contains the same information. -* `GET /info` now includes `no-new-privileges` in the `SecurityOptions` string - list when this option is enabled globally. This change is not versioned, and - affects all API versions if the daemon has this patch. - -## v1.42 API changes - -[Docker Engine API v1.42](https://docs.docker.com/engine/api/v1.42/) documentation - -* Removed the `BuilderSize` field on the `GET /system/df` endpoint. This field - was introduced in API 1.31 as part of an experimental feature, and no longer - used since API 1.40. - Use field `BuildCache` instead to track storage used by the builder component. -* `POST /containers/{id}/stop` and `POST /containers/{id}/restart` now accept a - `signal` query parameter, which allows overriding the container's default stop- - signal. -* `GET /images/json` now accepts query parameter `shared-size`. When set `true`, - images returned will include `SharedSize`, which provides the size on disk shared - with other images present on the system. -* `GET /system/df` now accepts query parameter `type`. When set, - computes and returns data only for the specified object type. - The parameter can be specified multiple times to select several object types. - Supported values are: `container`, `image`, `volume`, `build-cache`. -* `GET /system/df` can now be used concurrently. If a request is made while a - previous request is still being processed, the request will receive the result - of the already running calculation, once completed. Previously, an error - (`a disk usage operation is already running`) would be returned in this - situation. This change is not versioned, and affects all API versions if the - daemon has this patch. -* The `POST /images/create` now supports both the operating system and architecture - that is passed through the `platform` query parameter when using the `fromSrc` - option to import an image from an archive. Previously, only the operating system - was used and the architecture was ignored. If no `platform` option is set, the - host's operating system and architecture as used as default. This change is not - versioned, and affects all API versions if the daemon has this patch. -* The `POST /containers/{id}/wait` endpoint now returns a `400` status code if an - invalid `condition` is provided (on API 1.30 and up). -* Removed the `KernelMemory` field from the `POST /containers/create` and - `POST /containers/{id}/update` endpoints, any value it is set to will be ignored - on API version `v1.42` and up. Older API versions still accept this field, but - may take no effect, depending on the kernel version and OCI runtime in use. -* `GET /containers/{id}/json` now omits the `KernelMemory` and `KernelMemoryTCP` - if they are not set. -* `GET /info` now omits the `KernelMemory` and `KernelMemoryTCP` if they are not - supported by the host or host's configuration (if cgroups v2 are in use). -* `GET /_ping` and `HEAD /_ping` now return `Builder-Version` by default. - This header contains the default builder to use, and is a recommendation as - advertised by the daemon. However, it is up to the client to choose which builder - to use. - - The default value on Linux is version "2" (BuildKit), but the daemon can be - configured to recommend version "1" (classic Builder). Windows does not yet - support BuildKit for native Windows images, and uses "1" (classic builder) as - a default. - - This change is not versioned, and affects all API versions if the daemon has - this patch. -* `GET /_ping` and `HEAD /_ping` now return a `Swarm` header, which allows a - client to detect if Swarm is enabled on the daemon, without having to call - additional endpoints. - This change is not versioned, and affects all API versions if the daemon has - this patch. Clients must consider this header "optional", and fall back to - using other endpoints to get this information if the header is not present. - - The `Swarm` header can contain one of the following values: - - - "inactive" - - "pending" - - "error" - - "locked" - - "active/worker" - - "active/manager" -* `POST /containers/create` for Windows containers now accepts a new syntax in - `HostConfig.Resources.Devices.PathOnHost`. As well as the existing `class/<GUID>` - syntax, `<IDType>://<ID>` is now recognised. Support for specific `<IDType>` values - depends on the underlying implementation and Windows version. This change is not - versioned, and affects all API versions if the daemon has this patch. -* `GET /containers/{id}/attach`, `GET /exec/{id}/start`, `GET /containers/{id}/logs` - `GET /services/{id}/logs` and `GET /tasks/{id}/logs` now set Content-Type header - to `application/vnd.docker.multiplexed-stream` when a multiplexed stdout/stderr - stream is sent to client, `application/vnd.docker.raw-stream` otherwise. -* `POST /volumes/create` now accepts a new `ClusterVolumeSpec` to create a cluster - volume (CNI). This option can only be used if the daemon is a Swarm manager. - The Volume response on creation now also can contain a `ClusterVolume` field - with information about the created volume. -* The `BuildCache.Parent` field, as returned by `GET /system/df` is deprecated - and is now omitted. API versions before v1.42 continue to include this field. -* `GET /system/df` now includes a new `Parents` field, for "build-cache" records, - which contains a list of parent IDs for the build-cache record. -* Volume information returned by `GET /volumes/{name}`, `GET /volumes` and - `GET /system/df` can now contain a `ClusterVolume` if the volume is a cluster - volume (requires the daemon to be a Swarm manager). -* The `Volume` type, as returned by `Added new `ClusterVolume` fields -* Added a new `PUT /volumes{name}` endpoint to update cluster volumes (CNI). - Cluster volumes are only supported if the daemon is a Swarm manager. -* `GET /containers/{name}/attach/ws` endpoint now accepts `stdin`, `stdout` and - `stderr` query parameters to only attach to configured streams. - - NOTE: These parameters were documented before in older API versions, but not - actually supported. API versions before v1.42 continue to ignore these parameters - and default to attaching to all streams. To preserve the pre-v1.42 behavior, - set all three query parameters (`?stdin=1,stdout=1,stderr=1`). -* `POST /containers/create` on Linux now respects the `HostConfig.ConsoleSize` property. - Container is immediately created with the desired terminal size and clients no longer - need to set the desired size on their own. -* `POST /containers/create` allow to set `CreateMountpoint` for host path to be - created if missing. This brings parity with `Binds` -* `POST /containers/create` rejects request if BindOptions|VolumeOptions|TmpfsOptions - is set with a non-matching mount Type. -* `POST /containers/{id}/exec` now accepts an optional `ConsoleSize` parameter. - It allows to set the console size of the executed process immediately when it's created. -* `POST /volumes/prune` will now only prune "anonymous" volumes (volumes which were not given a name) by default. A new filter parameter `all` can be set to a truth-y value (`true`, `1`) to get the old behavior. - -## v1.41 API changes - -[Docker Engine API v1.41](https://docs.docker.com/engine/api/v1.41/) documentation - -* `GET /events` now returns `prune` events after pruning resources have completed. - Prune events are returned for `container`, `network`, `volume`, `image`, and - `builder`, and have a `reclaimed` attribute, indicating the amount of space - reclaimed (in bytes). -* `GET /info` now returns a `CgroupVersion` field, containing the cgroup version. -* `GET /info` now returns a `DefaultAddressPools` field, containing a list of - custom default address pools for local networks, which can be specified in the - `daemon.json` file or `--default-address-pool` dockerd option. -* `POST /services/create` and `POST /services/{id}/update` now supports `BindOptions.NonRecursive`. -* The `ClusterStore` and `ClusterAdvertise` fields in `GET /info` are deprecated - and are now omitted if they contain an empty value. This change is not versioned, - and affects all API versions if the daemon has this patch. -* The `filter` (singular) query parameter, which was deprecated in favor of the - `filters` option in Docker 1.13, has now been removed from the `GET /images/json` - endpoint. The parameter remains available when using API version 1.40 or below. -* `GET /services` now returns `CapAdd` and `CapDrop` as part of the `ContainerSpec`. -* `GET /services/{id}` now returns `CapAdd` and `CapDrop` as part of the `ContainerSpec`. -* `POST /services/create` now accepts `CapAdd` and `CapDrop` as part of the `ContainerSpec`. -* `POST /services/{id}/update` now accepts `CapAdd` and `CapDrop` as part of the `ContainerSpec`. -* `GET /tasks` now returns `CapAdd` and `CapDrop` as part of the `ContainerSpec`. -* `GET /tasks/{id}` now returns `CapAdd` and `CapDrop` as part of the `ContainerSpec`. -* `GET /services` now returns `Pids` in `TaskTemplate.Resources.Limits`. -* `GET /services/{id}` now returns `Pids` in `TaskTemplate.Resources.Limits`. -* `POST /services/create` now accepts `Pids` in `TaskTemplate.Resources.Limits`. -* `POST /services/{id}/update` now accepts `Pids` in `TaskTemplate.Resources.Limits` - to limit the maximum number of PIDs. -* `GET /tasks` now returns `Pids` in `TaskTemplate.Resources.Limits`. -* `GET /tasks/{id}` now returns `Pids` in `TaskTemplate.Resources.Limits`. -* `POST /containers/create` now accepts a `platform` query parameter in the format - `os[/arch[/variant]]`. - - When set, the daemon checks if the requested image is present in the local image - cache with the given OS and Architecture, and otherwise returns a `404` status. - - If the option is _not_ set, the host's native OS and Architecture are used to - look up the image in the image cache. However, if no platform is passed and the - given image _does_ exist in the local image cache, but its OS or architecture - do not match, the container is created with the available image, and a warning - is added to the `Warnings` field in the response, for example; - - WARNING: The requested image's platform (linux/arm64/v8) does not - match the detected host platform (linux/amd64) and no - specific platform was requested - -* `POST /containers/create` on Linux now accepts the `HostConfig.CgroupnsMode` property. - Set the property to `host` to create the container in the daemon's cgroup namespace, or - `private` to create the container in its own private cgroup namespace. The per-daemon - default is `host`, and can be changed by using the`CgroupNamespaceMode` daemon configuration - parameter. -* `GET /info` now returns an `OSVersion` field, containing the operating system's - version. This change is not versioned, and affects all API versions if the daemon - has this patch. -* `GET /info` no longer returns the `SystemStatus` field if it does not have a - value set.

For more information on creating organizations, see [Create your organization](orgs.md). - -### What's an organization name or namespace? - -The organization name, sometimes referred to as the organization namespace or the organization ID, is the unique identifier of a Docker organization. The organization name can't be the same as an existing Docker ID. - -### What are roles? - -A role is a collection of permissions granted to members. Roles define access to perform actions in Docker Hub like creating repositories, managing tags, or viewing teams. See [Roles and permissions](roles-and-permissions.md). - -### What’s a team? - -A team is a group of Docker users that belong to an organization. An organization can have multiple teams.

If you have a trademark for your namespace, [Docker Support](https://hub.docker.com/support/contact/) can retrieve the Docker ID for you. - -### How do I add an organization owner? - -An existing owner can add additional team members as organization owners. You can [invite a member](../../admin/organization/members.md#invite-members) and assign them the owner role in Docker Hub or the Docker Admin Console. - -### How do I know how many active users are part of my organization? - -If your organization uses a Software Asset Management tool, you can use it to find out how many users have Docker Desktop installed. If your organization doesn't use this software, you can run an internal survey to find out who is using Docker Desktop. See [Identify your Docker users and their Docker accounts](../../admin/organization/onboard.md#step-1-identify-your-docker-users-and-their-docker-accounts). With a Docker Business subscription, you can manage members in your identity provider and automatically provision them to your Docker organization with [SSO](../../security/for-admins/single-sign-on/_index.md) or [SCIM](../../security/for-admins/provisioning/scim.md). - -### Do users first need to authenticate with Docker before an owner can add them to an organization? - -No. Organization owners can invite users with their email address, and also assign them to a team during the invite process. - -### Can I force my organization's members to authenticate before using Docker Desktop and are there any benefits? - -Yes. You can [enforce sign-in](../../security/for-admins/configure-sign-in.md) and some benefits are: - -- Administrators can enforce features like [Image Access Management](../../security/for-admins/image-access-management.md) and [Registry Access Management](../../security/for-admins/registry-access-management.md). - - Administrators can ensure compliance by blocking Docker Desktop usage for users who don't sign in as members of the organization. - -### If a user has their personal email associated with a user account in Docker Hub, do they have to convert to using the organization's domain before they can be invited to join an organization? - -Yes. When SSO is enabled for your organization, each user must sign in with the company’s domain. However, the user can retain their personal credentials and create a new Docker ID associated with their organization's domain. - -### Can I convert my personal user account (Docker ID) to an organization account? - -Yes. You can convert your user account to an organization account. Once you -convert a user account into an organization, it's not possible to -revert it to a personal user account. For prerequisites and instructions, see -[Convert an account into an organization](convert-account.md). - -### Our users create Docker Hub accounts through self-service. How do we know when the total number of users for the requested licenses has been met? Is it possible to add more members to the organization than the total number of licenses? - -There isn't any automatic notification when the total number of users for the requested licenses has been met. However, if the number of team -members exceed the number of licenses, you will receive an error informing you -to contact the administrator due to lack of seats. You can [add seats](/subscription/core-subscription/add-seats/) if needed. - -### How can I merge organization accounts? - -You can downgrade a secondary organization and transition your users and data to a primary organization. See [Merge organizations](../organization/orgs.md#merge-organizations). - -### Do organization invitees take up seats? - -Yes. A user invited to an organization will take up one of the provisioned -seats, even if that user hasn’t accepted their invitation yet. Organization -owners can manage the list of invitees through the **Invitees** tab on the organization settings page in Docker Hub, or in the **Members** page in Admin Console. - -### Do organization owners take a seat? - -Yes. Organization owners will take up a seat. - -### What is the difference between user, invitee, seat, and member? - -User may refer to a Docker user with a Docker ID. - -An invitee is a user that an administrator has invited to join an organization, but has not yet accepted their invitation. - -Seats is the number of planned members within an organization. - -Member may refer to a user that has received and accepted an invitation to join an organization. Member can also refer to a member of a team within an organization. - -### If there are two organizations and a user belongs to both organizations, do they take up two seats? - -Yes. In a scenario where a user belongs to two organizations, they take up one seat in each organization. - -### Is it possible to set permissions for repositories within an organization? - -Yes. You can configure repository access on a per-team basis. For example, you -can specify that all teams within an organization have **Read and Write** access -to repositories A and B, whereas only specific teams have **Admin** access. Org -owners have full administrative access to all repositories within the -organization. See [Configure repository permissions for a team](manage-a-team.md#configure-repository-permissions-for-a-team). Administrators can also assign members the editor role, which grants administrative permissions for repositories across the namespace of the organization. See [Roles and permissions](../../security/for-admins/roles-and-permissions.md). - -### Does my organization need to use Docker's registry? - -A registry is a hosted service containing repositories of images that responds to the Registry API. Docker Hub is Docker's primary registry, but you can use Docker with other container image registries. You can access the default registry by browsing to [Docker Hub](https://hub.docker.com) or using the `docker search` command. diff --git a/content/admin/images/remove-owner.png b/content/admin/images/remove-owner.png deleted file mode 100644 index 8bda546ddb8e..000000000000 Binary files a/content/admin/images/remove-owner.png and /dev/null differ diff --git a/content/admin/images/team-repo-permission.png b/content/admin/images/team-repo-permission.png deleted file mode 100644 index e5fab7466713..000000000000 Binary files a/content/admin/images/team-repo-permission.png and /dev/null differ diff --git a/content/admin/organization/_index.md b/content/admin/organization/_index.md deleted file mode 100644 index 6cd964324de8..000000000000 --- a/content/admin/organization/_index.md +++ /dev/null @@ -1,52 +0,0 @@ ---- -description: Learn about managing organizations in Docker including how they relate to teams, how to onboard, and more -keywords: organizations, admin, overview -title: Organization administration overview -grid: -- title: Onboard your organization - description: Learn how to onboard and secure your organization. - icon: explore - link: /admin/organization/onboard -- title: Manage members - description: Explore how to manage members. - icon: group_add - link: /admin/organization/members/ -- title: Activity logs - description: Learn how to audit the activities of your members. - icon: feed - link: /admin/organization/activity-logs/ -- title: Image Access Management - description: Control which types of images your developers can pull. - icon: photo_library - link: /admin/organization/image-access/ -- title: Registry Access Management - description: Define which registries your developers can access. - icon: home_storage - link: /admin/organization/registry-access/ -- title: Organization settings - description: Configure information for your organization and manage settings. - icon: settings - link: /admin/organization/general-settings/ -- title: SSO and SCIM - description: 'Set up [Single Sign-On](/security/for-admins/single-sign-on/) - and [SCIM](/security/for-admins/provisioning/scim/) for your organization. - - ' - icon: key -- title: Domain management - description: Add, verify, and audit your domains. - link: /admin/organization/security-settings/domains/ - icon: domain_verification -- title: FAQs - description: Explore common organization FAQs. - link: /faq/admin/organization-faqs/ - icon: help ---- - -{{< include "admin-org-overview.md" >}} - -To create an organization, see [Create your organization](../organization/orgs.md). - -Learn how to administer an organization in the following sections. - -{{< grid >}} diff --git a/content/admin/organization/activity-logs.md b/content/admin/organization/activity-logs.md deleted file mode 100644 index 0c471d044410..000000000000 --- a/content/admin/organization/activity-logs.md +++ /dev/null @@ -1,91 +0,0 @@ ---- -description: Learn about activity logs. -keywords: team, organization, activity, log, audit, activities -title: Activity logs -aliases: -- /docker-hub/audit-log/ ---- - -Activity logs display a chronological list of activities that occur at organization and repository levels.

A smaller base image not only offers -portability and fast downloads, but also shrinks the size of your image and -minimizes the number of vulnerabilities introduced through the dependencies. - -You should also consider using two types of base image: one for building and -unit testing, and another (typically slimmer) image for production. In the -later stages of development, your image may not require build tools such as -compilers, build systems, and debugging tools. A small image with minimal -dependencies can considerably lower the attack surface. - -## Rebuild your images often - -Docker images are immutable. Building an image is taking a snapshot of that -image at that moment. That includes any base images, libraries, or other -software you use in your build.

Over time, -that tag may resolve to a different underlying version of the `ubuntu` image, -as the publisher rebuilds the image with new security patches and updated -libraries. Using the `--no-cache`, you can avoid cache hits and ensure a fresh -download of base images and dependencies. - -```dockerfile -# syntax=docker/dockerfile:1 -FROM ubuntu:24.04 -RUN apt-get -y update && apt-get install -y python -``` - -Also consider [pinning base image versions](#pin-base-image-versions). - -## Exclude with .dockerignore - -To exclude files not relevant to the build, without restructuring your source -repository, use a `.dockerignore` file. This file supports exclusion patterns -similar to `.gitignore` files. - -For example, to exclude all files with the `.md` extension: - -```plaintext -*.md -``` - -For information on creating one, see -[Dockerignore file](../../build/building/context.md#dockerignore-files). - -## Create ephemeral containers - -The image defined by your Dockerfile should generate containers that are as -ephemeral as possible. Ephemeral means that the container can be stopped -and destroyed, then rebuilt and replaced with an absolute minimum set up and -configuration. - -Refer to [Processes](https://12factor.net/processes) under _The Twelve-factor App_ -methodology to get a feel for the motivations of running containers in such a -stateless fashion. - -## Don't install unnecessary packages - -Avoid installing extra or unnecessary packages just because they might be nice to have. For example, you don’t need to include a text editor in a database image. - -When you avoid installing extra or unnecessary packages, your images have reduced complexity, reduced dependencies, reduced file sizes, and reduced build times. - -## Decouple applications - -Each container should have only one concern. Decoupling applications into -multiple containers makes it easier to scale horizontally and reuse containers. -For instance, a web application stack might consist of three separate -containers, each with its own unique image, to manage the web application, -database, and an in-memory cache in a decoupled manner. - -Limiting each container to one process is a good rule of thumb, but it's not a -hard and fast rule. For example, not only can containers be -[spawned with an init process](../../engine/reference/run.md#specify-an-init-process), -some programs might spawn additional processes of their own accord. For -instance, [Celery](https://docs.celeryproject.org/) can spawn multiple worker -processes, and [Apache](https://httpd.apache.org/) can create one process per -request. - -Use your best judgment to keep containers as clean and modular as possible. If -containers depend on each other, you can use [Docker container networks](../../network/index.md) -to ensure that these containers can communicate. - -## Sort multi-line arguments - -Whenever possible, sort multi-line arguments alphanumerically to make maintenance easier. -This helps to avoid duplication of packages and make the -list much easier to update. This also makes PRs a lot easier to read and -review. Adding a space before a backslash (`\`) helps as well. - -Here’s an example from the [buildpack-deps image](https://github.com/docker-library/buildpack-deps): - -```dockerfile -RUN apt-get update && apt-get install -y \ - bzr \ - cvs \ - git \ - mercurial \ - subversion \ - && rm -rf /var/lib/apt/lists/* -``` - -## Leverage build cache - -When building an image, Docker steps through the instructions in your -Dockerfile, executing each in the order specified. For each instruction, Docker -checks whether it can reuse the instruction from the build cache. - -Understanding how the build cache works, and how cache invalidation occurs, -is critical for ensuring faster builds. -For more information about the Docker build cache and how to optimize your builds, -see [Docker build cache](../../build/cache/_index.md). - -## Pin base image versions - -Image tags are mutable, meaning a publisher can update a tag to point to a new -image. This is useful because it lets publishers update tags to point to -newer versions of an image. And as an image consumer, it means you -automatically get the new version when you re-build your image. - -For example, if you specify `FROM alpine:3.19` in your Dockerfile, `3.19` -resolves to the latest patch version for `3.19`. - -```dockerfile -# syntax=docker/dockerfile:1 -FROM alpine:3.19 -``` - -At one point in time, the `3.19` tag might point to version 3.19.1 of the -image. If you rebuild the image 3 months later, the same tag might point to a -different version, such as 3.19.4. This publishing workflow is best practice, -and most publishers use this tagging strategy, but it isn't enforced. - -The downside with this is that you're not guaranteed to get the same for every -build. This could result in breaking changes, and it means you also don't have -an audit trail of the exact image versions that you're using. - -To fully secure your supply chain integrity, you can pin the image version to a -specific digest. By pinning your images to a digest, you're guaranteed to -always use the same image version, even if a publisher replaces the tag with a -new image. For example, the following Dockerfile pins the Alpine image to the -same tag as earlier, `3.19`, but this time with a digest reference as well. - -```dockerfile -# syntax=docker/dockerfile:1 -FROM alpine:3.19@sha256:13b7e62e8df80264dbb747995705a986aa530415763a6c58f84a3ca8af9a5bcd -``` - -With this Dockerfile, even if the publisher updates the `3.19` tag, your builds -would still use the pinned image version: -`13b7e62e8df80264dbb747995705a986aa530415763a6c58f84a3ca8af9a5bcd`. - -While this helps you avoid unexpected changes, it's also more tedious to have -to look up and include the image digest for base image versions manually each -time you want to update it. And you're opting out of automated security fixes, -which is likely something you want to get. - -Docker Scout has a built-in [**Outdated base images** -policy](../../scout/policy/_index.md#outdated-base-images) that checks for -whether the base image version you're using is in fact the latest version. This -policy also checks if pinned digests in your Dockerfile correspond to the -correct version. If a publisher updates an image that you've pinned, the policy -evaluation returns a non-compliant status, indicating that you should update -your image. - -Docker Scout also supports an automated remediation workflow for keeping your -base images up-to-date. When a new image digest is available, Docker Scout can -automatically raise a pull request on your repository to update your -Dockerfiles to use the latest version. This is better than using a tag that -changes the version automatically, because you're in control and you have an -audit trail of when and how the change occurred. - -For more information about automatically updating your base images with Docker -Scout, see -[Remediation](../../scout/policy/remediation.md#automatic-base-image-updates) - -## Build and test your images in CI - -When you check in a change to source control or create a pull request, use -[GitHub Actions](../ci/github-actions/_index.md) or another CI/CD pipeline to -automatically build and tag a Docker image and test it. - -## Dockerfile instructions - -Follow these recommendations on how to properly use the [Dockerfile instructions](../../reference/dockerfile.md) -to create an efficient and maintainable Dockerfile. - -### FROM - -Whenever possible, use current official images as the basis for your -images. Docker recommends the [Alpine image](https://hub.docker.com/_/alpine/) as it -is tightly controlled and small in size (currently under 6 MB), while still -being a full Linux distribution. - -For more information about the `FROM` instruction, see [Dockerfile reference for the FROM instruction](../../reference/dockerfile.md#from). - -### LABEL - -You can add labels to your image to help organize images by project, record -licensing information, to aid in automation, or for other reasons. For each -label, add a line beginning with `LABEL` with one or more key-value pairs. -The following examples show the different acceptable formats. Explanatory comments are included inline. - -Strings with spaces must be quoted or the spaces must be escaped. Inner -quote characters (`"`), must also be escaped. For example: - -```dockerfile -# Set one or more individual labels -LABEL com.example.version="0.0.1-beta" -LABEL vendor1="ACME Incorporated" -LABEL vendor2=ZENITH\ Incorporated -LABEL com.example.release-date="2015-02-12" -LABEL com.example.version.is-production="" -``` - -An image can have more than one label. Prior to Docker 1.10, it was recommended -to combine all labels into a single `LABEL` instruction, to prevent extra layers -from being created. This is no longer necessary, but combining labels is still -supported. For example: - -```dockerfile -# Set multiple labels on one line -LABEL com.example.version="0.0.1-beta" com.example.release-date="2015-02-12" -``` - -The above example can also be written as: - -```dockerfile -# Set multiple labels at once, using line-continuation characters to break long lines -LABEL vendor=ACME\ Incorporated \ - com.example.is-beta= \ - com.example.is-production="" \ - com.example.version="0.0.1-beta" \ - com.example.release-date="2015-02-12" -``` - -See [Understanding object labels](../../config/labels-custom-metadata.md) -for guidelines about acceptable label keys and values. For information about -querying labels, refer to the items related to filtering in -[Managing labels on objects](../../config/labels-custom-metadata.md#manage-labels-on-objects). -See also [LABEL](../../reference/dockerfile.md#label) in the Dockerfile reference. - -### RUN - -Split long or complex `RUN` statements on multiple lines separated with -backslashes to make your Dockerfile more readable, understandable, and -maintainable. - -For example, you can chain commands with the `&&` operator, and use -use escape characters to break long commands into multiple lines. - -```dockerfile -RUN apt-get update && apt-get install -y \ - package-bar \ - package-baz \ - package-foo -``` - -By default, backslash escapes a newline character, but you can change it with -the [`escape` directive](../../reference/dockerfile.md#escape). - -You can also use here documents to run multiple commands without chaining them -with a pipeline operator: - -```dockerfile -RUN < /number -``` - -Docker executes these commands using the `/bin/sh -c` interpreter, which only -evaluates the exit code of the last operation in the pipe to determine success. -In the example above, this build step succeeds and produces a new image so long -as the `wc -l` command succeeds, even if the `wget` command fails. - -If you want the command to fail due to an error at any stage in the pipe, -prepend `set -o pipefail &&` to ensure that an unexpected error prevents the -build from inadvertently succeeding. For example: - -```dockerfile -RUN set -o pipefail && wget -O - https://some.site | wc -l > /number -``` - -> **Note** -> -> Not all shells support the `-o pipefail` option. -> -> In cases such as the `dash` shell on -> Debian-based images, consider using the _exec_ form of `RUN` to explicitly -> choose a shell that does support the `pipefail` option. For example: -> -> ```dockerfile -> RUN ["/bin/bash", "-c", "set -o pipefail && wget -O - https://some.site | wc -l > /number"] -> ``` - -### CMD - -The `CMD` instruction should be used to run the software contained in your -image, along with any arguments. `CMD` should almost always be used in the form -of `CMD ["executable", "param1", "param2"]`. Thus, if the image is for a -service, such as Apache and Rails, you would run something like `CMD -["apache2","-DFOREGROUND"]`. Indeed, this form of the instruction is recommended -for any service-based image. - -In most other cases, `CMD` should be given an interactive shell, such as bash, -python and perl. For example, `CMD ["perl", "-de0"]`, `CMD ["python"]`, or `CMD -["php", "-a"]`. Using this form means that when you execute something like -`docker run -it python`, you’ll get dropped into a usable shell, ready to go. -`CMD` should rarely be used in the manner of `CMD ["param", "param"]` in -conjunction with [`ENTRYPOINT`](../../reference/dockerfile.md#entrypoint), unless -you and your expected users are already quite familiar with how `ENTRYPOINT` -works. - -For more information about `CMD`, see [Dockerfile reference for the CMD instruction](../../reference/dockerfile.md#cmd). - -### EXPOSE - -The `EXPOSE` instruction indicates the ports on which a container listens -for connections. Consequently, you should use the common, traditional port for -your application. For example, an image containing the Apache web server would -use `EXPOSE 80`, while an image containing MongoDB would use `EXPOSE 27017` and -so on. - -For external access, your users can execute `docker run` with a flag indicating -how to map the specified port to the port of their choice. -For container linking, Docker provides environment variables for the path from -the recipient container back to the source (for example, `MYSQL_PORT_3306_TCP`). - -For more information about `EXPOSE`, see [Dockerfile reference for the EXPOSE instruction](../../reference/dockerfile.md#expose). - -### ENV - -To make new software easier to run, you can use `ENV` to update the -`PATH` environment variable for the software your container installs. For -example, `ENV PATH=/usr/local/nginx/bin:$PATH` ensures that `CMD ["nginx"]` -just works. - -The `ENV` instruction is also useful for providing the required environment -variables specific to services you want to containerize, such as Postgres’s -`PGDATA`. - -Lastly, `ENV` can also be used to set commonly used version numbers so that -version bumps are easier to maintain, as seen in the following example: - -```dockerfile -ENV PG_MAJOR=9.3 -ENV PG_VERSION=9.3.4 -RUN curl -SL https://example.com/postgres-$PG_VERSION.tar.xz | tar -xJC /usr/src/postgres && â€Ļ -ENV PATH=/usr/local/postgres-$PG_MAJOR/bin:$PATH -``` - -Similar to having constant variables in a program, as opposed to hard-coding -values, this approach lets you change a single `ENV` instruction to -automatically bump the version of the software in your container. - -Each `ENV` line creates a new intermediate layer, just like `RUN` commands. This -means that even if you unset the environment variable in a future layer, it -still persists in this layer and its value can be dumped. You can test this by -creating a Dockerfile like the following, and then building it. - -```dockerfile -# syntax=docker/dockerfile:1 -FROM alpine -ENV ADMIN_USER="mark" -RUN echo $ADMIN_USER > ./mark -RUN unset ADMIN_USER -``` - -```console -$ docker run --rm test sh -c 'echo $ADMIN_USER' - -mark -``` - -To prevent this, and really unset the environment variable, use a `RUN` command -with shell commands, to set, use, and unset the variable all in a single layer. -You can separate your commands with `;` or `&&`. If you use the second method, -and one of the commands fails, the `docker build` also fails. This is usually a -good idea. Using `\` as a line continuation character for Linux Dockerfiles -improves readability. You could also put all of the commands into a shell script -and have the `RUN` command just run that shell script. - -```dockerfile -# syntax=docker/dockerfile:1 -FROM alpine -RUN export ADMIN_USER="mark" \ - && echo $ADMIN_USER > ./mark \ - && unset ADMIN_USER -CMD sh -``` - -```console -$ docker run --rm test sh -c 'echo $ADMIN_USER' - -``` - -For more information about `ENV`, see [Dockerfile reference for the ENV instruction](../../reference/dockerfile.md#env). - -### ADD or COPY - -`ADD` and `COPY` are functionally similar. `COPY` supports basic copying of -files into the container, from the [build context](../../build/building/context.md) -or from a stage in a [multi-stage build](../../build/building/multi-stage.md). -`ADD` supports features for fetching files from remote HTTPS and Git URLs, and -extracting tar files automatically when adding files from the build context. - -You'll mostly want to use `COPY` for copying files from one stage to another in -a multi-stage build. If you need to add files from the build context to the -container temporarily to execute a `RUN` instruction, you can often substitute -the `COPY` instruction with a bind mount instead. For example, to temporarily -add a `requirements.txt` file for a `RUN pip install` instruction: - -```dockerfile -RUN --mount=type=bind,source=requirements.txt,target=/tmp/requirements.txt \ - pip install --requirement /tmp/requirements.txt -``` - -Bind mounts are more efficient than `COPY` for including files from the build -context in the container. Note that bind-mounted files are only added -temporarily for a single `RUN` instruction, and don't persist in the final -image. If you need to include files from the build context in the final image, -use `COPY`. - -The `ADD` instruction is best for when you need to download a remote artifact -as part of your build. `ADD` is better than manually adding files using -something like `wget` and `tar`, because it ensures a more precise build cache. -`ADD` also has built-in support for checksum validation of the remote -resources, and a protocol for parsing branches, tags, and subdirectories from -[Git URLs](../../reference/cli/docker/image/build.md#git-repositories). - -The following example uses `ADD` to download a .NET installer. Combined with -multi-stage builds, only the .NET runtime remains in the final stage, no -intermediate files. - -```dockerfile -# syntax=docker/dockerfile:1 - -FROM scratch AS src -ARG DOTNET_VERSION=8.0.0-preview.6.23329.7 -ADD --checksum=sha256:270d731bd08040c6a3228115de1f74b91cf441c584139ff8f8f6503447cebdbb \ - https://dotnetcli.azureedge.net/dotnet/Runtime/$DOTNET_VERSION/dotnet-runtime-$DOTNET_VERSION-linux-arm64.tar.gz /dotnet.tar.gz - -FROM mcr.microsoft.com/dotnet/runtime-deps:8.0.0-preview.6-bookworm-slim-arm64v8 AS installer - -# Retrieve .NET Runtime -RUN --mount=from=src,target=/src < **Note** -> -> Consider an explicit UID/GID. -> -> Users and groups in an image are assigned a non-deterministic UID/GID in that -> the "next" UID/GID is assigned regardless of image rebuilds.

The Debian/Ubuntu `adduser` wrapper does not support this flag. - -Avoid installing or using `sudo` as it has unpredictable TTY and -signal-forwarding behavior that can cause problems. If you absolutely need -functionality similar to `sudo`, such as initializing the daemon as `root` but -running it as non-`root`, consider using [“gosu”](https://github.com/tianon/gosu). - -Lastly, to reduce layers and complexity, avoid switching `USER` back and forth -frequently. - -For more information about `USER`, see [Dockerfile reference for the USER instruction](../../reference/dockerfile.md#user). - -### WORKDIR - -For clarity and reliability, you should always use absolute paths for your -`WORKDIR`. Also, you should use `WORKDIR` instead of proliferating instructions -like `RUN cd â€Ļ && do-something`, which are hard to read, troubleshoot, and -maintain. - -For more information about `WORKDIR`, see [Dockerfile reference for the WORKDIR instruction](../../reference/dockerfile.md#workdir). - -### ONBUILD - -An `ONBUILD` command executes after the current Dockerfile build completes. -`ONBUILD` executes in any child image derived `FROM` the current image. Think -of the `ONBUILD` command as an instruction that the parent Dockerfile gives -to the child Dockerfile. - -A Docker build executes `ONBUILD` commands before any command in a child -Dockerfile. - -`ONBUILD` is useful for images that are going to be built `FROM` a given -image. For example, you would use `ONBUILD` for a language stack image that -builds arbitrary user software written in that language within the -Dockerfile, as you can see in [Ruby’s `ONBUILD` variants](https://github.com/docker-library/ruby/blob/c43fef8a60cea31eb9e7d960a076d633cb62ba8d/2.4/jessie/onbuild/Dockerfile). - -Images built with `ONBUILD` should get a separate tag. For example, -`ruby:1.9-onbuild` or `ruby:2.0-onbuild`. - -Be careful when putting `ADD` or `COPY` in `ONBUILD`. The onbuild image -fails catastrophically if the new build's context is missing the resource being -added. Adding a separate tag, as recommended above, helps mitigate this by -allowing the Dockerfile author to make a choice. - -For more information about `ONBUILD`, see [Dockerfile reference for the ONBUILD instruction](../../reference/dockerfile.md#onbuild). diff --git a/content/build/building/context.md b/content/build/building/context.md deleted file mode 100644 index 9b47bc9c5e34..000000000000 --- a/content/build/building/context.md +++ /dev/null @@ -1,566 +0,0 @@ ---- -title: Build context -description: Learn how to use the build context to access files from your Dockerfile -keywords: build, buildx, buildkit, context, git, tarball, stdin ---- - -The `docker build` and `docker buildx build` commands build Docker images from -a [Dockerfile](../../reference/dockerfile.md) and a context. - -## What is a build context? - -The build context is the set of files that your build can access. -The positional argument that you pass to the build command specifies the -context that you want to use for the build: - -```console -$ docker build [OPTIONS] PATH | URL | - - ^^^^^^^^^^^^^^ -``` - -You can pass any of the following inputs as the context for a build: - -- The relative or absolute path to a local directory -- A remote URL of a Git repository, tarball, or plain-text file -- A plain-text file or tarball piped to the `docker build` command through standard input - -### Filesystem contexts - -When your build context is a local directory, a remote Git repository, or a tar -file, then that becomes the set of files that the builder can access during the -build.

Because of this, you can run -containers of non-native architectures like the `arm32v7` or `ppc64le` -automatically. - -#### QEMU without Docker Desktop - -If you're running Docker Engine on Linux, without Docker Desktop, you must -install statically compiled QEMU binaries and register them with -[`binfmt_misc`](https://en.wikipedia.org/wiki/Binfmt_misc). This enables QEMU -to execute non-native file formats for emulation. The QEMU binaries must be -statically compiled and registered with the `fix_binary` flag. This requires a -kernel version 4.8 or later, and `binfmt-support` version 2.1.7 or later. - -Once QEMU is installed and the executable types are registered on the host OS, -they work transparently inside containers. You can verify your registration by -checking if `F` is among the flags in `/proc/sys/fs/binfmt_misc/qemu-*`. While -Docker Desktop comes preconfigured with `binfmt_misc` support for additional -platforms, for other installations it likely needs to be installed using -[`tonistiigi/binfmt`](https://github.com/tonistiigi/binfmt) image: - -```console -$ docker run --privileged --rm tonistiigi/binfmt --install all -``` - -### Multiple native nodes - -Using multiple native nodes provide better support for more complicated cases -that QEMU can't handle, and also provides better performance. - -You can add additional nodes to a builder using the `--append` flag. - -The following command creates a multi-node builder from Docker contexts named -`node-amd64` and `node-arm64`. This example assumes that you've already added -those contexts. - -```console -$ docker buildx create --use --name mybuild node-amd64 -mybuild -$ docker buildx create --append --name mybuild node-arm64 -$ docker buildx build --platform linux/amd64,linux/arm64 . -``` - -While this approach has advantages over emulation, managing multi-node builders -introduces some overhead of setting up and managing builder clusters. -Alternatively, you can use Docker Build Cloud, a service that provides managed -multi-node builders on Docker's infrastructure. With Docker Build Cloud, you -get native multi-platform ARM and X86 builders without the burden of -maintaining them. Using cloud builders also provides additional benefits, such -as a shared build cache. - -After signing up for Docker Build Cloud, add the builder to your local -environment and start building. - -```console -$ docker buildx create --driver cloud / -cloud-- -$ docker build \ - --builder cloud-- \ - --platform linux/amd64,linux/arm64,linux/arm/v7 \ - --tag \ - --push . -``` - -For more information, see [Docker Build Cloud](/build-cloud/_index.md). - -### Cross-compilation - -Depending on your project, if the programming language you use has good support -for cross-compilation, you can leverage multi-stage builds to build binaries -for target platforms from the native architecture of the builder. Special build -arguments, such as `BUILDPLATFORM` and `TARGETPLATFORM`, are automatically -available for use in your Dockerfile. - -In the following example, the `FROM` instruction is pinned to the native -platform of the builder (using the `--platform=$BUILDPLATFORM` option) to -prevent emulation from kicking in. Then the pre-defined `$BUILDPLATFORM` and -`$TARGETPLATFORM` build arguments are interpolated in a `RUN` instruction. In -this case, the values are just printed to stdout with `echo`, but this -illustrates how you would pass them to the compiler for cross-compilation. - -```dockerfile -# syntax=docker/dockerfile:1 -FROM --platform=$BUILDPLATFORM golang:alpine AS build -ARG TARGETPLATFORM -ARG BUILDPLATFORM -RUN echo "I am running on $BUILDPLATFORM, building for $TARGETPLATFORM" > /log -FROM alpine -COPY --from=build /log /log -``` - -## Getting started - -Run the [`docker buildx ls` command](../../reference/cli/docker/buildx/ls.md) -to list the existing builders: - -```console -$ docker buildx ls -NAME/NODE DRIVER/ENDPOINT STATUS BUILDKIT PLATFORMS -default * docker - default default running v0.11.6 linux/amd64, linux/arm64, linux/arm/v7, linux/arm/v6 -``` - -This displays the default builtin driver, that uses the BuildKit server -components built directly into the Docker Engine, also known as the [`docker` driver](../drivers/docker.md). - -Create a new builder using the [`docker-container` driver](../drivers/docker-container.md) -which gives you access to more complex features like multi-platform builds -and the more advanced cache exporters, which are currently unsupported in the -default `docker` driver: - -```console -$ docker buildx create --name mybuilder --bootstrap --use -``` - -Now listing the existing builders again, you can see that the new builder is -registered: - -```console -$ docker buildx ls -NAME/NODE DRIVER/ENDPOINT STATUS BUILDKIT PLATFORMS -mybuilder * docker-container -

The first `RUN` command installs `pip`, which ensures that we can -use the command to install the flask web framework. - -### Copying files - -The next instruction uses the -[`COPY` instruction](../../reference/dockerfile.md#copy) to copy the -`hello.py` file from the local build context into the root directory of our image. - -```dockerfile -COPY hello.py / -``` - -A [build context](./context.md) is the set of files that you can access -in Dockerfile instructions such as `COPY` and `ADD`. - -After the `COPY` instruction, the `hello.py` file is added to the filesystem -of the build container. - -### Setting environment variables - -If your application uses environment variables, you can set environment variables -in your Docker build using the [`ENV` instruction](../../reference/dockerfile.md#env). - -```dockerfile -ENV FLASK_APP=hello -``` - -This sets a Linux environment variable we'll need later. Flask, the framework -used in this example, uses this variable to start the application.

The -caching model is entirely rewritten compared to the legacy builder. Rather than -using heuristics to compare images, LLB directly tracks the checksums of build -graphs and content mounted to specific operations. This makes it much faster, -more precise, and portable.

Scaling -is configurable using the following driver options: - -- `replicas=N` - - This scales the number of BuildKit pods to the desired size. By default, it - only creates a single pod. Increasing the number of replicas lets you take - advantage of multiple nodes in your cluster. - -- `requests.cpu`, `requests.memory`, `requests.ephemeral-storage`, `limits.cpu`, `limits.memory`, `limits.ephemeral-storage` - - These options allow requesting and limiting the resources available to each - BuildKit pod according to the official Kubernetes documentation - [here](https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/). - -For example, to create 4 replica BuildKit pods: - -```console -$ docker buildx create \ - --bootstrap \ - --name=kube \ - --driver=kubernetes \ - --driver-opt=namespace=buildkit,replicas=4 -``` - -Listing the pods, you get this: - -```console -$ kubectl -n buildkit get deployments -NAME READY UP-TO-DATE AVAILABLE AGE -kube0 4/4 4 4 8s - -$ kubectl -n buildkit get pods -NAME READY STATUS RESTARTS AGE -kube0-6977cdcb75-48ld2 1/1 Running 0 8s -kube0-6977cdcb75-rkc6b 1/1 Running 0 8s -kube0-6977cdcb75-vb4ks 1/1 Running 0 8s -kube0-6977cdcb75-z4fzs 1/1 Running 0 8s -``` - -Additionally, you can use the `loadbalance=(sticky|random)` option to control -the load-balancing behavior when there are multiple replicas. `random` selects -random nodes from the node pool, providing an even workload distribution across -replicas. `sticky` (the default) attempts to connect the same build performed -multiple times to the same node each time, ensuring better use of local cache. - -For more information on scalability, see the options for -[`docker buildx create`](../../reference/cli/docker/buildx/create.md#driver-opt). - -## Node assignment - -The Kubernetes driver allows you to control the scheduling of BuildKit pods -using the `nodeSelector` and `tolerations` driver options. -You can also set the `schedulername` option if you want to use a custom scheduler altogether. - -You can use the `annotations` and `labels` driver options to apply additional -metadata to the deployments and pods that's hosting your builders. - -The value of the `nodeSelector` parameter is a comma-separated string of -key-value pairs, where the key is the node label and the value is the label -text. For example: `"nodeselector=kubernetes.io/arch=arm64"` - -The `tolerations` parameter is a semicolon-separated list of taints. It accepts -the same values as the Kubernetes manifest. Each `tolerations` entry specifies -a taint key and the value, operator, or effect. For example: -`"tolerations=key=foo,value=bar;key=foo2,operator=exists;key=foo3,effect=NoSchedule"` - -These options accept CSV-delimited strings as values. Due to quoting rules for -shell commands, you must wrap the values in single quotes. You can even wrap all -of `--driver-opt` in single quotes, for example: - -```console -$ docker buildx create \ - --bootstrap \ - --name=kube \ - --driver=kubernetes \ - '--driver-opt="nodeselector=label1=value1,label2=value2","tolerations=key=key1,value=value1"' -``` - -## Multi-platform builds - -The Kubernetes driver has support for creating -[multi-platform images](../building/multi-platform.md), -either using QEMU or by leveraging the native architecture of nodes. - -### QEMU - -Like the `docker-container` driver, the Kubernetes driver also supports using -[QEMU](https://www.qemu.org/) (user -mode) to build images for non-native platforms. Include the `--platform` flag -and specify which platforms you want to output to. - -For example, to build a Linux image for `amd64` and `arm64`: - -```console -$ docker buildx build \ - --builder=kube \ - --platform=linux/amd64,linux/arm64 \ - -t / \ - --push . -``` - -> **Warning** -> -> QEMU performs full-CPU emulation of non-native platforms, which is much -> slower than native builds. Compute-heavy tasks like compilation and -> compression/decompression will likely take a large performance hit. -{ .warning } - -Using a custom BuildKit image or invoking non-native binaries in builds may -require that you explicitly turn on QEMU using the `qemu.install` option when -creating the builder: - -```console -$ docker buildx create \ - --bootstrap \ - --name=kube \ - --driver=kubernetes \ - --driver-opt=namespace=buildkit,qemu.install=true -``` - -### Native - -If you have access to cluster nodes of different architectures, the Kubernetes -driver can take advantage of these for native builds. To do this, use the -`--append` flag of `docker buildx create`. - -First, create your builder with explicit support for a single architecture, for -example `amd64`: - -```console -$ docker buildx create \ - --bootstrap \ - --name=kube \ - --driver=kubernetes \ - --platform=linux/amd64 \ - --node=builder-amd64 \ - --driver-opt=namespace=buildkit,nodeselector="kubernetes.io/arch=amd64" -``` - -This creates a Buildx builder named `kube`, containing a single builder node -named `builder-amd64`. Assigning a node name using `--node` is optional. Buildx -generates a random node name if you don't provide one. - -Note that the Buildx concept of a node isn't the same as the Kubernetes concept -of a node. A Buildx node in this case could connect multiple Kubernetes nodes of -the same architecture together. - -With the `kube` builder created, you can now introduce another architecture into -the mix using `--append`. For example, to add `arm64`: - -```console -$ docker buildx create \ - --append \ - --bootstrap \ - --name=kube \ - --driver=kubernetes \ - --platform=linux/arm64 \ - --node=builder-arm64 \ - --driver-opt=namespace=buildkit,nodeselector="kubernetes.io/arch=arm64" -``` - -Listing your builders shows both nodes for the `kube` builder: - -```console -$ docker buildx ls -NAME/NODE DRIVER/ENDPOINT STATUS PLATFORMS -kube kubernetes - builder-amd64 kubernetes:///kube?deployment=builder-amd64&kubeconfig= running linux/amd64*, linux/amd64/v2, linux/amd64/v3, linux/386 - builder-arm64 kubernetes:///kube?deployment=builder-arm64&kubeconfig= running linux/arm64* -``` - -You can now build multi-arch `amd64` and `arm64` images, by specifying those -platforms together in your build command: - -```console -$ docker buildx build --builder=kube --platform=linux/amd64,linux/arm64 -t / --push . -``` - -You can repeat the `buildx create --append` command for as many architectures -that you want to support. - -## Rootless mode - -The Kubernetes driver supports rootless mode. For more information on how -rootless mode works, and it's requirements, see -[here](https://github.com/moby/buildkit/blob/master/docs/rootless.md). - -To turn it on in your cluster, you can use the `rootless=true` driver option: - -```console -$ docker buildx create \ - --name=kube \ - --driver=kubernetes \ - --driver-opt=namespace=buildkit,rootless=true -``` - -This will create your pods without `securityContext.privileged`. - -Requires Kubernetes version 1.19 or later.

It can be a single value or a list. - -```yml -dns: 8.8.8.8 -``` - -```yml -dns: - - 8.8.8.8 - - 9.9.9.9 -``` - -### dns_opt - -`dns_opt` list custom DNS options to be passed to the container’s DNS resolver (`/etc/resolv.conf` file on Linux). - -```yml -dns_opt: - - use-vc - - no-tld-query -``` - -### dns_search - -`dns_search` defines custom DNS search domains to set on container network interface configuration. It can be a single value or a list. - -```yml -dns_search: example.com -``` - -```yml -dns_search: - - dc1.example.com - - dc2.example.com -``` - -### domainname - -`domainname` declares a custom domain name to use for the service container. It must be a valid RFC 1123 hostname. - -### entrypoint - -`entrypoint` declares the default entrypoint for the service container. -This overrides the `ENTRYPOINT` instruction from the service's Dockerfile. - -If `entrypoint` is non-null, Compose ignores any default command from the image, for example the `CMD` -instruction in the Dockerfile. - -See also [`command`](#command) to set or override the default command to be executed by the entrypoint process. - -In its short form, the value can be defined as a string: -```yml -entrypoint: /code/entrypoint.sh -``` - -Alternatively, the value can also be a list, in a manner similar to the -[Dockerfile](https://docs.docker.com/reference/dockerfile/#cmd): - -```yml -entrypoint: - - php - - -d - - zend_extension=/usr/local/lib/php/extensions/no-debug-non-zts-20100525/xdebug.so - - -d - - memory_limit=-1 - - vendor/bin/phpunit -``` - -If the value is `null`, the default entrypoint from the image is used. - -If the value is `[]` (empty list) or `''` (empty string), the default entrypoint declared by the image is ignored, -i.e. overridden to be empty. - -### env_file - -{{< include "compose/services-env-file.md" >}} - -```yml -env_file: .env -``` - -`env_file` can also be a list. The files in the list are processed from the top down. For the same variable -specified in two env files, the value from the last file in the list stands. - -```yml -env_file: - - ./a.env - - ./b.env -``` - -List elements can also be declared as a mapping, which then lets you set an additional -attribute `required`. This defaults to `true`. When `required` is set to `false` and the `.env` file is missing, -Compose silently ignores the entry. - -```yml -env_file: - - path: ./default.env - required: true # default - - path: ./override.env - required: false -``` -> `required` attribute is available with Docker Compose version 2.24.0 or later. - -Relative path are resolved from the Compose file's parent folder. As absolute paths prevent the Compose -file from being portable, Compose warns you when such a path is used to set `env_file`. - -Environment variables declared in the [environment](#environment) section override these values. This holds true even if those values are -empty or undefined. - -#### Env_file format - -Each line in an `.env` file must be in `VAR[=[VAL]]` format. The following syntax rules apply: - -- Lines beginning with `#` are processed as comments and ignored. -- Blank lines are ignored. -- Unquoted and double-quoted (`"`) values have [Interpolation](12-interpolation.md) applied. -- Each line represents a key-value pair. Values can optionally be quoted. - - `VAR=VAL` -> `VAL` - - `VAR="VAL"` -> `VAL` - - `VAR='VAL'` -> `VAL` -- Inline comments for unquoted values must be preceded with a space. - - `VAR=VAL # comment` -> `VAL` - - `VAR=VAL# not a comment` -> `VAL# not a comment` -- Inline comments for quoted values must follow the closing quote. - - `VAR="VAL # not a comment"` -> `VAL # not a comment` - - `VAR="VAL" # comment` -> `VAL` -- Single-quoted (`'`) values are used literally. - - `VAR='$OTHER'` -> `$OTHER` - - `VAR='${OTHER}'` -> `${OTHER}` -- Quotes can be escaped with `\`. - - `VAR='Let\'s go!'` -> `Let's go!` - - `VAR="{\"hello\": \"json\"}"` -> `{"hello": "json"}` -- Common shell escape sequences including `\n`, `\r`, `\t`, and `\\` are supported in double-quoted values. - - `VAR="some\tvalue"` -> `some value` - - `VAR='some\tvalue'` -> `some\tvalue` - - `VAR=some\tvalue` -> `some\tvalue` - -`VAL` may be omitted, in such cases the variable value is an empty string. -`=VAL` may be omitted, in such cases the variable is unset. - -```bash -# Set Rails/Rack environment -RACK_ENV=development -VAR="quoted" -``` - -### environment - -{{< include "compose/services-environment.md" >}} - -Environment variables can be declared by a single key (no value to equals sign). In this case Compose -relies on you to resolve the value. If the value is not resolved, the variable -is unset and is removed from the service container environment. - -Map syntax: - -```yml -environment: - RACK_ENV: development - SHOW: "true" - USER_INPUT: -``` - -Array syntax: - -```yml -environment: - - RACK_ENV=development - - SHOW=true - - USER_INPUT -``` - -When both `env_file` and `environment` are set for a service, values set by `environment` have precedence. - -### expose - -`expose` defines the (incoming) port or a range of ports that Compose exposes from the container. These ports must be -accessible to linked services and should not be published to the host machine. Only the internal container -ports can be specified. - -Syntax is `/[]` or `/[]` for a port range. -When not explicitly set, `tcp` protocol is used. - -```yml -expose: - - "3000" - - "8000" - - "8080-8085/tcp" -``` - -> **Note** -> -> If the Dockerfile for the image already exposes ports, it is visible to other containers on the network even if `expose` is not set in your Compose file. - -### extends - -`extends` lets you share common configurations among different files, or even different projects entirely. With `extends` you can define a common set of service options in one place and refer to it from anywhere. You can refer to another Compose file and select a service you want to also use in your own application, with the ability to override some attributes for your own needs. - -You can use `extends` on any service together with other configuration keys. The `extends` value must be a mapping -defined with a required `service` and an optional `file` key. - -```yaml -extends: - file: common.yml - service: webapp -``` - -- `service`: Defines the name of the service being referenced as a base, for example `web` or `database`. -- `file`: The location of a Compose configuration file defining that service. - -When a service uses `extends`, it can also specify dependencies on other resources, an explicit `volumes` declaration for instance. However, it's important to note that `extends` does not automatically incorporate the target volume definition into the extending Compose file. Instead, you are responsible for ensuring that an equivalent resource exists for the service being extended to maintain consistency. Docker Compose verifies that a resource with the referenced ID is present within the Compose model. - -Dependencies on other resources in an `extends` target can be: -- An explicit reference by `volumes`, `networks`, `configs`, `secrets`, `links`, `volumes_from` or `depends_on` -- A reference to another service using the `service:{name}` syntax in namespace declaration (`ipc`, `pid`, `network_mode`) - -Circular references with `extends` are not supported, Compose returns an error when one is detected. - -#### Finding referenced service - -`file` value can be: - -- Not present. - This indicates that another service within the same Compose file is being referenced. -- File path, which can be either: - - Relative path. This path is considered as relative to the location of the main Compose - file. - - Absolute path. - -A service denoted by `service` must be present in the identified referenced Compose file. -Compose returns an error if: - -- The service denoted by `service` is not found. -- The Compose file denoted by `file` is not found. - -#### Merging service definitions - -Two service definitions, the main one in the current Compose file and the referenced one -specified by `extends`, are merged in the following way: - -- Mappings: Keys in mappings of the main service definition override keys in mappings - of the referenced service definition. Keys that aren't overridden are included as is. -- Sequences: Items are combined together into a new sequence. The order of elements is - preserved with the referenced items coming first and main items after. -- Scalars: Keys in the main service definition take precedence over keys in the - referenced one. - -##### Mappings - -The following keys should be treated as mappings: `annotations`, `build.args`, `build.labels`, -`build.extra_hosts`, `deploy.labels`, `deploy.update_config`, `deploy.rollback_config`, -`deploy.restart_policy`, `deploy.resources.limits`, `environment`, `healthcheck`, -`labels`, `logging.options`, `sysctls`, `storage_opt`, `extra_hosts`, `ulimits`. - -One exception that applies to `healthcheck` is that the main mapping cannot specify -`disable: true` unless the referenced mapping also specifies `disable: true`. Compose returns an error in this case. - -For example, the input below: - -```yaml -services: - common: - image: busybox - environment: - TZ: utc - PORT: 80 - cli: - extends: - service: common - environment: - PORT: 8080 -``` - -Produces the following configuration for the `cli` service. The same output is -produced if array syntax is used. - -```yaml -environment: - PORT: 8080 - TZ: utc -image: busybox -``` - -Items under `blkio_config.device_read_bps`, `blkio_config.device_read_iops`, -`blkio_config.device_write_bps`, `blkio_config.device_write_iops`, `devices` and -`volumes` are also treated as mappings where key is the target path inside the -container. - -For example, the input below: - -```yaml -services: - common: - image: busybox - volumes: - - common-volume:/var/lib/backup/data:rw - cli: - extends: - service: common - volumes: - - cli-volume:/var/lib/backup/data:ro -``` - -Produces the following configuration for the `cli` service. Note that the mounted path -now points to the new volume name and `ro` flag was applied. - -```yaml -image: busybox -volumes: -- cli-volume:/var/lib/backup/data:ro -``` - -If the referenced service definition contains `extends` mapping, the items under it -are simply copied into the new merged definition. The merging process is then kicked -off again until no `extends` keys are remaining. - -For example, the input below: - -```yaml -services: - base: - image: busybox - user: root - common: - image: busybox - extends: - service: base - cli: - extends: - service: common -``` - -Produces the following configuration for the `cli` service. Here, `cli` services -gets `user` key from `common` service, which in turn gets this key from `base` -service. - -```yaml -image: busybox -user: root -``` - -##### Sequences - -The following keys should be treated as sequences: `cap_add`, `cap_drop`, `configs`, -`deploy.placement.constraints`, `deploy.placement.preferences`, -`deploy.reservations.generic_resources`, `device_cgroup_rules`, `expose`, -`external_links`, `ports`, `secrets`, `security_opt`. -Any duplicates resulting from the merge are removed so that the sequence only -contains unique elements. - -For example, the input below: - -```yaml -services: - common: - image: busybox - security_opt: - - label:role:ROLE - cli: - extends: - service: common - security_opt: - - label:user:USER -``` - -Produces the following configuration for the `cli` service. - -```yaml -image: busybox -security_opt: -- label:role:ROLE -- label:user:USER -``` - -In case list syntax is used, the following keys should also be treated as sequences: -`dns`, `dns_search`, `env_file`, `tmpfs`. Unlike sequence fields mentioned above, -duplicates resulting from the merge are not removed. - -##### Scalars - -Any other allowed keys in the service definition should be treated as scalars. - -### external_links - -`external_links` link service containers to services managed outside of your Compose application. -`external_links` define the name of an existing service to retrieve using the platform lookup mechanism. -An alias of the form `SERVICE:ALIAS` can be specified. - -```yml -external_links: - - redis - - database:mysql - - database:postgresql -``` - -### extra_hosts - -`extra_hosts` adds hostname mappings to the container network interface configuration (`/etc/hosts` for Linux). - -#### Short syntax - -Short syntax uses plain strings in a list. Values must set hostname and IP address for additional hosts in the form of `HOSTNAME=IP`. - -```yml -extra_hosts: - - "somehost=162.242.195.82" - - "otherhost=50.31.209.229" - - "myhostv6=::1" -``` - -IPv6 addresses can be enclosed in square brackets, for example: - -```yml -extra_hosts: - - "myhostv6=[::1]" -``` - -The separator `=` is preferred, but `:` can also be used. Introduced in Docker Compose version [2.24.1](../release-notes.md#2241). For example: - -```yml -extra_hosts: - - "somehost:162.242.195.82" - - "myhostv6:::1" -``` - -#### Long syntax - -Alternatively, `extra_hosts` can be set as a mapping between hostname(s) and IP(s) - -```yml -extra_hosts: - somehost: "162.242.195.82" - otherhost: "50.31.209.229" - myhostv6: "::1" -``` - -Compose creates a matching entry with the IP address and hostname in the container's network -configuration, which means for Linux `/etc/hosts` get extra lines: - -```console -162.242.195.82 somehost -50.31.209.229 otherhost -::1 myhostv6 -``` - -### group_add - -`group_add` specifies additional groups, by name or number, which the user inside the container must be a member of. - -An example of where this is useful is when multiple containers (running as different users) need to all read or write -the same file on a shared volume. That file can be owned by a group shared by all the containers, and specified in -`group_add`. - -```yml -services: - myservice: - image: alpine - group_add: - - mail -``` - -Running `id` inside the created container must show that the user belongs to the `mail` group, which would not have -been the case if `group_add` were not declared. - -### healthcheck - -{{< include "compose/services-healthcheck.md" >}} - -For more information on `HEALTHCHECK`, see the [Dockerfile reference](../../reference/dockerfile.md#healthcheck). - -```yml -healthcheck: - test: ["CMD", "curl", "-f", "http://localhost"] - interval: 1m30s - timeout: 10s - retries: 3 - start_period: 40s - start_interval: 5s -``` - -`interval`, `timeout`, `start_period`, and `start_interval` are [specified as durations](11-extension.md#specifying-durations). Introduced in Docker Compose version [2.20.2](../release-notes.md#2202) - -`test` defines the command Compose runs to check container health. It can be -either a string or a list. If it's a list, the first item must be either `NONE`, `CMD` or `CMD-SHELL`. -If it's a string, it's equivalent to specifying `CMD-SHELL` followed by that string. - -```yml -# Hit the local web app -test: ["CMD", "curl", "-f", "http://localhost"] -``` - -Using `CMD-SHELL` runs the command configured as a string using the container's default shell -(`/bin/sh` for Linux). Both forms below are equivalent: - -```yml -test: ["CMD-SHELL", "curl -f http://localhost || exit 1"] -``` - -```yml -test: curl -f https://localhost || exit 1 -``` - -`NONE` disables the healthcheck, and is mostly useful to disable the Healthcheck Dockerfile instruction set by the service's Docker image. Alternatively, -the healthcheck set by the image can be disabled by setting `disable: true`: - -```yml -healthcheck: - disable: true -``` - -### hostname - -`hostname` declares a custom host name to use for the service container. It must be a valid RFC 1123 hostname. - -### image - -`image` specifies the image to start the container from. `image` must follow the Open Container Specification -[addressable image format](https://github.com/opencontainers/org/blob/master/docs/docs/introduction/digests.md), -as `[/][/][:|@]`. - -```yml - image: redis - image: redis:5 - image: redis@sha256:0ed5d5928d4737458944eb604cc8509e245c3e19d02ad83935398bc4b991aac7 - image: library/redis - image: docker.io/library/redis - image: my_private.registry:5000/redis -``` - -If the image does not exist on the platform, Compose attempts to pull it based on the `pull_policy`. -If you are also using the [Compose Build Specification](build.md), there are alternative options for controlling the precedence of -pull over building the image from source, however pulling the image is the default behavior. - -`image` may be omitted from a Compose file as long as a `build` section is declared. If you are not using the Compose Build Specification, Compose won't work if `image` is missing from the Compose file. - -### init - -`init` runs an init process (PID 1) inside the container that forwards signals and reaps processes. -Set this option to `true` to enable this feature for the service. - -```yml -services: - web: - image: alpine:latest - init: true -``` - -The init binary that is used is platform specific. - -### ipc - -`ipc` configures the IPC isolation mode set by the service container. - -- `shareable`: Gives the container its own private IPC namespace, with a - possibility to share it with other containers. -- `service:{name}`: Makes the container join another container's - (`shareable`) IPC namespace. - -```yml - ipc: "shareable" - ipc: "service:[service name]" -``` - -### isolation - -`isolation` specifies a container’s isolation technology. Supported values are platform specific. - -### labels - -`labels` add metadata to containers. You can use either an array or a map. - -It's recommended that you use reverse-DNS notation to prevent your labels from conflicting with -those used by other software. - -```yml -labels: - com.example.description: "Accounting webapp" - com.example.department: "Finance" - com.example.label-with-empty-value: "" -``` - -```yml -labels: - - "com.example.description=Accounting webapp" - - "com.example.department=Finance" - - "com.example.label-with-empty-value" -``` - -Compose creates containers with canonical labels: - -- `com.docker.compose.project` set on all resources created by Compose to the user project name -- `com.docker.compose.service` set on service containers with service name as defined in the Compose file - -The `com.docker.compose` label prefix is reserved. Specifying labels with this prefix in the Compose file -results in a runtime error. - -### links - -`links` defines a network link to containers in another service. Either specify both the service name and -a link alias (`SERVICE:ALIAS`), or just the service name. - -```yml -web: - links: - - db - - db:database - - redis -``` - -Containers for the linked service are reachable at a hostname identical to the alias, or the service name -if no alias is specified. - -Links are not required to enable services to communicate. When no specific network configuration is set, -any service is able to reach any other service at that service’s name on the `default` network. If services -do declare networks they are attached to, `links` does not override the network configuration and services not -attached to a shared network are not be able to communicate. Compose doesn't warn you about a configuration mismatch. - -Links also express implicit dependency between services in the same way as -[depends_on](#depends_on), so they determine the order of service startup. - -### logging - -`logging` defines the logging configuration for the service. - -```yml -logging: - driver: syslog - options: - syslog-address: "tcp://192.168.0.42:123" -``` - -The `driver` name specifies a logging driver for the service's containers. The default and available values -are platform specific. Driver specific options can be set with `options` as key-value pairs. - -### mac_address - -> Available with Docker Compose version 2.24.0 and later. - -`mac_address` sets a MAC address for the service container. - -> **Note** -> Container runtimes might reject this value (ie. Docker Engine >= v25.0). In that case, you should use [networks.mac_address](#mac_address) instead. - -### mem_limit - -`mem_limit` configures a limit on the amount of memory a container can allocate, set as a string expressing a [byte value](11-extension.md#specifying-byte-values). - -When set, `mem_limit` must be consistent with the `limits.memory` attribute in the [Deploy Specification](deploy.md#memory). - -### mem_reservation - -`mem_reservation` configures a reservation on the amount of memory a container can allocate, set as a string expressing a [byte value](11-extension.md#specifying-byte-values). - -When set, `mem_reservation` must be consistent with the `reservations.memory` attribute in the [Deploy Specification](deploy.md#memory). - -### mem_swappiness - -`mem_swappiness` defines as a percentage, a value between 0 and 100, for the host kernel to swap out -anonymous memory pages used by a container. - -- `0`: Turns off anonymous page swapping. -- `100`: Sets all anonymous pages as swappable. - -The default value is platform specific. - -### memswap_limit - -`memswap_limit` defines the amount of memory the container is allowed to swap to disk. This is a modifier -attribute that only has meaning if [`memory`](deploy.md#memory) is also set. Using swap lets the container write excess -memory requirements to disk when the container has exhausted all the memory that is available to it. -There is a performance penalty for applications that swap memory to disk often. - -- If `memswap_limit` is set to a positive integer, then both `memory` and `memswap_limit` must be set. `memswap_limit` represents the total amount of memory and swap that can be used, and `memory` controls the amount used by non-swap memory. So if `memory`="300m" and `memswap_limit`="1g", the container can use 300m of memory and 700m (1g - 300m) swap. -- If `memswap_limit` is set to 0, the setting is ignored, and the value is treated as unset. -- If `memswap_limit` is set to the same value as `memory`, and `memory` is set to a positive integer, the container does not have access to swap. -- If `memswap_limit` is unset, and `memory` is set, the container can use as much swap as the `memory` setting, if the host container has swap memory configured. For instance, if `memory`="300m" and `memswap_limit` is not set, the container can use 600m in total of memory and swap. -- If `memswap_limit` is explicitly set to -1, the container is allowed to use unlimited swap, up to the amount available on the host system. - -### network_mode - -`network_mode` sets a service container's network mode. - -- `none`: Turns off all container networking. -- `host`: Gives the container raw access to the host's network interface. -- `service:{name}`: Gives the containers access to the specified service only. For more information, see [Container networks](../../network/_index.md#container-networks). - -```yml - network_mode: "host" - network_mode: "none" - network_mode: "service:[service name]" -``` - -When set, the [`networks`](#networks) attribute is not allowed and Compose rejects any -Compose file containing both attributes. - -### networks - -{{< include "compose/services-networks.md" >}} - -```yml -services: - some-service: - networks: - - some-network - - other-network -``` -For more information about the `networks` top-level element, see [Networks](06-networks.md). - -#### aliases - -`aliases` declares alternative hostnames for the service on the network. Other containers on the same -network can use either the service name or an alias to connect to one of the service's containers. - -Since `aliases` are network-scoped, the same service can have different aliases on different networks. - -> **Note** -> A network-wide alias can be shared by multiple containers, and even by multiple services. -> If it is, then exactly which container the name resolves to is not guaranteed. - -```yml -services: - some-service: - networks: - some-network: - aliases: - - alias1 - - alias3 - other-network: - aliases: - - alias2 -``` - -In the following example, service `frontend` is able to reach the `backend` service at -the hostname `backend` or `database` on the `back-tier` network. The service `monitoring` -is able to reach same `backend` service at `backend` or `mysql` on the `admin` network. - -```yml -services: - frontend: - image: example/webapp - networks: - - front-tier - - back-tier - - monitoring: - image: example/monitoring - networks: - - admin - - backend: - image: example/backend - networks: - back-tier: - aliases: - - database - admin: - aliases: - - mysql - -networks: - front-tier: - back-tier: - admin: -``` - -#### ipv4_address, ipv6_address - -Specify a static IP address for a service container when joining the network. - -The corresponding network configuration in the [top-level networks section](06-networks.md) must have an -`ipam` attribute with subnet configurations covering each static address. - -```yml -services: - frontend: - image: example/webapp - networks: - front-tier: - ipv4_address: 172.16.238.10 - ipv6_address: 2001:3984:3989::10 - -networks: - front-tier: - ipam: - driver: default - config: - - subnet: "172.16.238.0/24" - - subnet: "2001:3984:3989::/64" -``` - -#### link_local_ips - -`link_local_ips` specifies a list of link-local IPs. Link-local IPs are special IPs which belong to a well -known subnet and are purely managed by the operator, usually dependent on the architecture where they are -deployed. - -Example: - -```yaml -services: - app: - image: busybox - command: top - networks: - app_net: - link_local_ips: - - 57.123.22.11 - - 57.123.22.13 -networks: - app_net: - driver: bridge -``` - -#### mac_address - -{{< introduced compose 2.23.2 "../release-notes.md#2232" >}} - -`mac_address` sets the MAC address used by the service container when connecting to this particular network. - -#### priority - -`priority` indicates in which order Compose connects the service’s containers to its -networks. If unspecified, the default value is 0. - -In the following example, the app service connects to `app_net_1` first as it has the highest priority. It then connects to `app_net_3`, then `app_net_2`, which uses the default priority value of 0. - -```yaml -services: - app: - image: busybox - command: top - networks: - app_net_1: - priority: 1000 - app_net_2: - - app_net_3: - priority: 100 -networks: - app_net_1: - app_net_2: - app_net_3: -``` - -### oom_kill_disable - -If `oom_kill_disable` is set, Compose configures the platform so it won't kill the container in case -of memory starvation. - -### oom_score_adj - -`oom_score_adj` tunes the preference for containers to be killed by platform in case of memory starvation.

This grants the -container access to the secret and mounts it as read-only to `/run/secrets/` -within the container. The source name and destination mountpoint are both set -to the secret name. - -The following example uses the short syntax to grant the `frontend` service -access to the `server-certificate` secret.

If it is absolute, the path prevents the Compose file from being portable so Compose displays a warning. - -## Using `build` and `image` - -When Compose is confronted with both a `build` subsection for a service and an `image` attribute, it follows the rules defined by the [`pull_policy`](05-services.md#pull_policy) attribute. - -If `pull_policy` is missing from the service definition, Compose attempts to pull the image first and then builds from source if the image isn't found in the registry or platform cache. - - -## Publishing built images - -Compose with `build` support offers an option to push built images to a registry. When doing so, it doesn't try to push service images without an `image` attribute. Compose warns you about the missing `image` attribute which prevents images being pushed. - -## Illustrative example - -The following example illustrates Compose Build Specification concepts with a concrete sample application. The sample is non-normative. - -```yaml -services: - frontend: - image: example/webapp - build: ./webapp - - backend: - image: example/database - build: - context: backend - dockerfile: ../backend.Dockerfile - - custom: - build: ~/custom -``` - -When used to build service images from source, the Compose file creates three Docker images: - -* `example/webapp`: A Docker image is built using `webapp` sub-directory, within the Compose file's parent folder, as the Docker build context. Lack of a `Dockerfile` within this folder throws an error. -* `example/database`: A Docker image is built using `backend` sub-directory within the Compose file parent folder. `backend.Dockerfile` file is used to define build steps, this file is searched relative to the context path, which means `..` resolves to the Compose file's parent folder, so `backend.Dockerfile` is a sibling file. -* A Docker image is built using the `custom` directory with the user's HOME as the Docker context. Compose displays a warning about the non-portable path used to build image. - -On push, both `example/webapp` and `example/database` Docker images are pushed to the default registry. The `custom` service image is skipped as no `image` attribute is set and Compose displays a warning about this missing attribute. - -## Attributes - -The `build` subsection defines configuration options that are applied by Compose to build Docker images from source. -`build` can be specified either as a string containing a path to the build context or as a detailed structure: - -Using the string syntax, only the build context can be configured as either: -- A relative path to the Compose file's parent folder. This path must be a directory and must contain a `Dockerfile` - - ```yml - services: - webapp: - build: ./dir - ``` - -- A git repository URL. Git URLs accept context configuration in their fragment section, separated by a colon (`:`). -The first part represents the reference that Git checks out, and can be either a branch, a tag, or a remote reference. -The second part represents a subdirectory inside the repository that is used as a build context. - - ```yml - services: - webapp: - build: https://github.com/mycompany/example.git#branch_or_tag:subdirectory - ``` - -Alternatively `build` can be an object with fields defined as follows: - -### context - -`context` defines either a path to a directory containing a Dockerfile, or a URL to a git repository. - -When the value supplied is a relative path, it is interpreted as relative to the location of the Compose file. -Compose warns you about the absolute path used to define the build context as those prevent the Compose file -from being portable. - -```yml -build: - context: ./dir -``` - -```yml -services: - webapp: - build: https://github.com/mycompany/webapp.git -``` - -If not set explicitly, `context` defaults to project directory (`.`). - -### dockerfile - -`dockerfile` sets an alternate Dockerfile. A relative path is resolved from the build context. -Compose warns you about the absolute path used to define the Dockerfile as it prevents Compose files -from being portable. - -When set, `dockerfile_inline` attribute is not allowed and Compose -rejects any Compose file having both set. - -```yml -build: - context: . - dockerfile: webapp.Dockerfile -``` - -### dockerfile_inline - -{{< introduced compose 2.17.0 "../release-notes.md#2170" >}} - -`dockerfile_inline` defines the Dockerfile content as an inlined string in a Compose file. When set, the `dockerfile` -attribute is not allowed and Compose rejects any Compose file having both set. - -Use of YAML multi-line string syntax is recommended to define the Dockerfile content: - -```yml -build: - context: . - dockerfile_inline: | - FROM baseimage - RUN some command -``` - - -### args - -`args` define build arguments, i.e. Dockerfile `ARG` values. - -Using the following Dockerfile as an example: - -```Dockerfile -ARG GIT_COMMIT -RUN echo "Based on commit: $GIT_COMMIT" -``` - -`args` can be set in the Compose file under the `build` key to define `GIT_COMMIT`. `args` can be set as a mapping or a list: - -```yml -build: - context: . - args: - GIT_COMMIT: cdc3b19 -``` - -```yml -build: - context: . - args: - - GIT_COMMIT=cdc3b19 -``` - -Values can be omitted when specifying a build argument, in which case its value at build time must be obtained by user interaction, -otherwise the build arg won't be set when building the Docker image. - -```yml -args: - - GIT_COMMIT -``` - -### ssh - -`ssh` defines SSH authentications that the image builder should use during image build (e.g., cloning private repository). - -`ssh` property syntax can be either: -* `default`: Let the builder connect to the ssh-agent. -* `ID=path`: A key/value definition of an ID and the associated path. It can be either a [PEM](https://en.wikipedia.org/wiki/Privacy-Enhanced_Mail) file, or path to ssh-agent socket. - -```yaml -build: - context: . - ssh: - - default # mount the default ssh agent -``` -or -```yaml -build: - context: . - ssh: ["default"] # mount the default ssh agent -``` - -Using a custom id `myproject` with path to a local SSH key: -```yaml -build: - context: . - ssh: - - myproject=~/.ssh/myproject.pem -``` -The image builder can then rely on this to mount the SSH key during build. -For illustration, [BuildKit extended syntax](https://github.com/compose-spec/compose-spec/pull/234/%5Bmoby/buildkit@master/frontend/dockerfile/docs/syntax.md#run---mounttypessh%5D(https://github.com/moby/buildkit/blob/master/frontend/dockerfile/docs/syntax.md#run---mounttypessh)) can be used to mount the SSH key set by ID and access a secured resource: - -`RUN --mount=type=ssh,id=myproject git clone ...` - -### cache_from - -`cache_from` defines a list of sources the image builder should use for cache resolution. - -Cache location syntax follows the global format `[NAME|type=TYPE[,KEY=VALUE]]`. Simple `NAME` is actually a shortcut notation for `type=registry,ref=NAME`. - -Compose Build implementations may support custom types, the Compose Specification defines canonical types which must be supported: - -- `registry` to retrieve build cache from an OCI image set by key `ref` - - -```yml -build: - context: . - cache_from: - - alpine:latest - - type=local,src=path/to/cache - - type=gha -``` - -Unsupported caches are ignored and don't prevent you from building images. - -### cache_to - -`cache_to` defines a list of export locations to be used to share build cache with future builds. - -```yml -build: - context: . - cache_to: - - user/app:cache - - type=local,dest=path/to/cache -``` - -Cache target is defined using the same `type=TYPE[,KEY=VALUE]` syntax defined by [`cache_from`](#cache_from). - -Unsupported caches are ignored and don't prevent you from building images. - -### additional_contexts - -{{< introduced compose 2.17.0 "../release-notes.md#2170" >}} - -`additional_contexts` defines a list of named contexts the image builder should use during image build. - -`additional_contexts` can be a mapping or a list: - -```yml -build: - context: . - additional_contexts: - - resources=/path/to/resources - - app=docker-image://my-app:latest - - source=https://github.com/myuser/project.git -``` - -```yml -build: - context: . - additional_contexts: - resources: /path/to/resources - app: docker-image://my-app:latest - source: https://github.com/myuser/project.git -``` - -When used as a list, the syntax follows the `NAME=VALUE` format, where `VALUE` is a string. Validation beyond that -is the responsibility of the image builder (and is builder specific). Compose supports at least -absolute and relative paths to a directory AND Git repository URLs, like [context](#context) does. Other context flavours -must be prefixed to avoid ambiguity with a `type://` prefix. - -Compose warns you if the image builder does not support additional contexts and may list -the unused contexts. - -Illustrative examples of how this is used in Buildx can be found -[here](https://github.com/docker/buildx/blob/master/docs/reference/buildx_build.md#-additional-build-contexts---build-context). - -### extra_hosts - -`extra_hosts` adds hostname mappings at build-time. Use the same syntax as [extra_hosts](05-services.md#extra_hosts). - -```yml -extra_hosts: - - "somehost=162.242.195.82" - - "otherhost=50.31.209.229" - - "myhostv6=::1" -``` -IPv6 addresses can be enclosed in square brackets, for example: - -```yml -extra_hosts: - - "myhostv6=[::1]" -``` - -The separator `=` is preferred, but `:` can also be used. Introduced in Docker Compose version [2.24.1](../release-notes.md#2241). For example: - -```yml -extra_hosts: - - "somehost:162.242.195.82" - - "myhostv6:::1" -``` - -Compose creates matching entry with the IP address and hostname in the container's network -configuration, which means for Linux `/etc/hosts` will get extra lines: - -```text -162.242.195.82 somehost -50.31.209.229 otherhost -::1 myhostv6 -``` - -### isolation - -`isolation` specifies a build’s container isolation technology. Like [isolation](05-services.md#isolation), supported values -are platform specific. - -### privileged - -{{< introduced compose 2.15.0 "../release-notes.md#2" >}} - -`privileged` configures the service image to build with elevated privileges. Support and actual impacts are platform specific. - -```yml -build: - context: . - privileged: true -``` - -### labels - -`labels` add metadata to the resulting image. `labels` can be set either as an array or a map. - -It's recommended that you use reverse-DNS notation to prevent your labels from conflicting with other software. - -```yml -build: - context: . - labels: - com.example.description: "Accounting webapp" - com.example.department: "Finance" - com.example.label-with-empty-value: "" -``` - -```yml -build: - context: . - labels: - - "com.example.description=Accounting webapp" - - "com.example.department=Finance" - - "com.example.label-with-empty-value" -``` - -### no_cache - -`no_cache` disables image builder cache and enforces a full rebuild from source for all image layers. This only -applies to layers declared in the Dockerfile, referenced images COULD be retrieved from local image store whenever tag -has been updated on registry (see [pull](#pull)). - -### pull - -`pull` requires the image builder to pull referenced images (`FROM` Dockerfile directive), even if those are already -available in the local image store. - -### network - -Set the network containers connect to for the `RUN` instructions during build. - -```yaml -build: - context: . - network: host -``` - -```yaml -build: - context: . - network: custom_network_1 -``` - -Use `none` to disable networking during build: - -```yaml -build: - context: . - network: none -``` - -### shm_size - -`shm_size` sets the size of the shared memory (`/dev/shm` partition on Linux) allocated for building Docker images. Specify -as an integer value representing the number of bytes or as a string expressing a [byte value](11-extension.md#specifying-byte-values). - -```yml -build: - context: . - shm_size: '2gb' -``` - -```yaml -build: - context: . - shm_size: 10000000 -``` - -### target - -`target` defines the stage to build as defined inside a multi-stage `Dockerfile`. - -```yml -build: - context: . - target: prod -``` - -### secrets - -`secrets` grants access to sensitive data defined by [secrets](05-services.md#secrets) on a per-service build basis. Two -different syntax variants are supported: the short syntax and the long syntax. - -Compose reports an error if the secret isn't defined in the -[`secrets`](09-secrets.md) section of this Compose file. - -#### Short syntax - -The short syntax variant only specifies the secret name. This grants the -container access to the secret and mounts it as read-only to `/run/secrets/` -within the container. The source name and destination mountpoint are both set -to the secret name. - -The following example uses the short syntax to grant the build of the `frontend` service -access to the `server-certificate` secret. The value of `server-certificate` is set -to the contents of the file `./server.cert`. - -```yml -services: - frontend: - build: - context: . - secrets: - - server-certificate -secrets: - server-certificate: - file: ./server.cert -``` - -#### Long syntax - -The long syntax provides more granularity in how the secret is created within -the service's containers. - -- `source`: The name of the secret as it exists on the platform. -- `target`: The name of the file to be mounted in `/run/secrets/` in the - service's task containers. Defaults to `source` if not specified. -- `uid` and `gid`: The numeric UID or GID that owns the file within - `/run/secrets/` in the service's task containers. Default value is USER running container. -- `mode`: The [permissions](https://wintelguy.com/permissions-calc.pl) for the file to be mounted in `/run/secrets/` - in the service's task containers, in octal notation. - Default value is world-readable permissions (mode `0444`). - The writable bit must be ignored if set. The executable bit may be set. - -The following example sets the name of the `server-certificate` secret file to `server.crt` -within the container, sets the mode to `0440` (group-readable) and sets the user and group -to `103`. The value of `server-certificate` secret is provided by the platform through a lookup and -the secret lifecycle not directly managed by Compose. - -```yml -services: - frontend: - build: - context: . - secrets: - - source: server-certificate - target: server.cert - uid: "103" - gid: "103" - mode: 0440 -secrets: - server-certificate: - external: true -``` - -Service builds may be granted access to multiple secrets. Long and short syntax for secrets may be used in the -same Compose file. Defining a secret in the top-level `secrets` must not imply granting any service build access to it. -Such grant must be explicit within service specification as [secrets](05-services.md#secrets) service element. - -### tags - -`tags` defines a list of tag mappings that must be associated to the build image. This list comes in addition to -the `image` [property defined in the service section](05-services.md#image) - -```yml -tags: - - "myimage:mytag" - - "registry/username/myrepos:my-other-tag" -``` - -### ulimits - -{{< introduced compose 2.23.1 "../release-notes.md#2231" >}} - -`ulimits` overrides the default ulimits for a container.

It was written in Python, and is invoked with `docker-compose`. Typically, Compose V1 projects include a top-level version element in the compose.yml file, with values ranging from 2.0 to 3.8, which refer to the specific file formats. - -Version two of the Docker Compose command-line binary was announced in 2020, is written in Go, and is invoked with `docker compose`. Compose V2 ignores the version top-level element in the compose.yml file. - -For further information, see [History and development of Compose](intro/history.md). - -### What's the difference between `up`, `run`, and `start`? - -Typically, you want `docker compose up`. Use `up` to start or restart all the -services defined in a `compose.yml`. In the default "attached" -mode, you see all the logs from all the containers. In "detached" mode (`-d`), -Compose exits after starting the containers, but the containers continue to run -in the background. - -The `docker compose run` command is for running "one-off" or "adhoc" tasks. It -requires the service name you want to run and only starts containers for services -that the running service depends on. Use `run` to run tests or perform -an administrative task such as removing or adding data to a data volume -container. The `run` command acts like `docker run -ti` in that it opens an -interactive terminal to the container and returns an exit status matching the -exit status of the process in the container. - -The `docker compose start` command is useful only to restart containers -that were previously created but were stopped. It never creates new -containers. - -### Why do my services take 10 seconds to recreate or stop? - -The `docker compose stop` command attempts to stop a container by sending a `SIGTERM`. It then waits -for a [default timeout of 10 seconds](../reference/cli/docker/compose/stop.md). After the timeout, -a `SIGKILL` is sent to the container to forcefully kill it. If you -are waiting for this timeout, it means that your containers aren't shutting down -when they receive the `SIGTERM` signal. - -There has already been a lot written about this problem of -[processes handling signals](https://medium.com/@gchudnov/trapping-signals-in-docker-containers-7a57fdda7d86) -in containers. - -To fix this problem, try the following: - -- Make sure you're using the exec form of `CMD` and `ENTRYPOINT` -in your Dockerfile. - - For example use `["program", "arg1", "arg2"]` not `"program arg1 arg2"`. - Using the string form causes Docker to run your process using `bash` which - doesn't handle signals properly. Compose always uses the JSON form, so don't - worry if you override the command or entrypoint in your Compose file. - -- If you are able, modify the application that you're running to -add an explicit signal handler for `SIGTERM`. - -- Set the `stop_signal` to a signal which the application knows how to handle: - - ```yaml - services: - web: - build: . - stop_signal: SIGINT - ``` - -- If you can't modify the application, wrap the application in a lightweight init -system (like [s6](https://skarnet.org/software/s6/)) or a signal proxy (like -[dumb-init](https://github.com/Yelp/dumb-init) or -[tini](https://github.com/krallin/tini)). Either of these wrappers takes care of -handling `SIGTERM` properly. - -### How do I run multiple copies of a Compose file on the same host? - -Compose uses the project name to create unique identifiers for all of a -project's containers and other resources. To run multiple copies of a project, -set a custom project name using the [`-p` command line option](reference/index.md) -or the [`COMPOSE_PROJECT_NAME` environment variable](environment-variables/envvars.md#compose_project_name). - -### Can I use JSON instead of YAML for my Compose file? - -Yes. [YAML is a superset of JSON](https://stackoverflow.com/a/1729545/444646) so -any JSON file should be valid YAML. To use a JSON file with Compose, -specify the filename to use, for example: - -```console -$ docker compose -f docker-compose.json up -``` - -### Should I include my code with `COPY`/`ADD` or a volume? - -You can add your code to the image using `COPY` or `ADD` directive in a -`Dockerfile`. This is useful if you need to relocate your code along with the -Docker image, for example when you're sending code to another environment -(production, CI, etc). - -Use a `volume` if you want to make changes to your code and see them -reflected immediately, for example when you're developing code and your server -supports hot code reloading or live-reload. - -There may be cases where you want to use both. You can have the image -include the code using a `COPY`, and use a `volume` in your Compose file to -include the code from the host during development.

Re-using containers means that you can make changes to your environment very quickly. - -- Portability across environments: Compose supports variables in the Compose file. You can use these variables to customize your composition for different environments, or different users. - -- Extensive community and support: Docker Compose benefits from a vibrant and active community, which means abundant resources, tutorials, and support. This community-driven ecosystem contributes to the continuous improvement of Docker Compose and helps users troubleshoot issues effectively. - -## Common use cases of Docker Compose - -Compose can be used in many different ways. Some common use cases are outlined -below. - -### Development environments - -When you're developing software, the ability to run an application in an -isolated environment and interact with it is crucial. The Compose command -line tool can be used to create the environment and interact with it. - -The [Compose file](../compose-file/_index.md) provides a way to document and configure -all of the application's service dependencies (databases, queues, caches, -web service APIs, etc). Using the Compose command line tool you can create -and start one or more containers for each dependency with a single command -(`docker compose up`). - -Together, these features provide a convenient way for you to get -started on a project. Compose can reduce a multi-page "developer getting -started guide" to a single machine-readable Compose file and a few commands. - -### Automated testing environments - -An important part of any Continuous Deployment or Continuous Integration process -is the automated test suite. Automated end-to-end testing requires an -environment in which to run tests. Compose provides a convenient way to create -and destroy isolated testing environments for your test suite. By defining the full environment in a [Compose file](../compose-file/_index.md), you can create and destroy these environments in just a few commands: - -```console -$ docker compose up -d -$ ./run_tests -$ docker compose down -``` - -### Single host deployments - -Compose has traditionally been focused on development and testing workflows, -but with each release we're making progress on more production-oriented features. - -For details on using production-oriented features, see -[Compose in production](../production.md). - -## What's next? - -- [Learn about the history of Compose](history.md) -- [Understand how Compose works](../compose-application-model.md) -- [Quickstart](../gettingstarted.md) diff --git a/content/compose/intro/history.md b/content/compose/intro/history.md deleted file mode 100644 index 7fe9b35cc1fb..000000000000 --- a/content/compose/intro/history.md +++ /dev/null @@ -1,48 +0,0 @@ ---- -title: History and development of Docker Compose -description: History of Compose V1 and Compose YAML schema versioning -keywords: compose, compose yaml, swarm, migration, compatibility, docker compose vs docker-compose -aliases: -- /compose/history/ ---- - -This page provides: - - A brief history of the development of the Docker Compose CLI - - A clear explanation of the major versions and file formats that make up Compose V1 and Compose V2 - - The main differences between Compose V1 and Compose V2 - -## Introduction - -![Image showing the main differences between Compose V1 and Compose V2](../images/v1-versus-v2.png) - -The image above shows that the currently supported version of the Docker Compose CLI is Compose V2 which is defined by the [Compose Specification](../compose-file/_index.md). - -It also provides a quick snapshot of the differences in file formats, command-line syntax, and top-level elements.

Use `-f` to get the old default behavior. - -- Booleans are no longer allows as values for mappings in the Compose file - (for keys `environment`, `labels` and `extra_hosts`). Previously this - was a warning. Boolean values should be quoted so they become string values. - -### New Features - -- Compose now looks for a `.env` file in the directory where it's run and - reads any environment variables defined inside, if they're not already - set in the shell environment. This lets you easily set defaults for - variables used in the Compose file, or for any of the `COMPOSE_*` or - `DOCKER_*` variables. - -- Added a `--remove-orphans` flag to both `docker-compose up` and - `docker-compose down` to remove containers for services that were removed - from the Compose file. - -- Added a `--all` flag to `docker-compose rm` to include containers created - by `docker-compose run`.

It now shows a warning if an image is automatically built when the - flag is not used. - -- Added the `docker-compose exec` command for executing a process in a running - container. - - -### Bug fixes - -- `docker-compose down` now removes containers created by - `docker-compose run`. - -- A more appropriate error is shown when a timeout is hit during `up` when - using a tty. - -- Fixed a bug in `docker-compose down` where it would abort if some resources - had already been removed. - -- Fixed a bug where changes to network aliases would not trigger a service - to be recreated. - -- Fix a bug where a log message was printed about creating a new volume - when it already existed. - -- Fixed a bug where interrupting `up` would not always shut down containers. - -- Fixed a bug where `log_opt` and `log_driver` were not properly carried over - when extending services in the v1 Compose file format. - -- Fixed a bug where empty values for build args would cause file validation - to fail. - -## 1.6.2 - -(2016-02-23) - -- Fixed a bug where connecting to a TLS-enabled Docker Engine would fail with - a certificate verification error. - -## 1.6.1 - -(2016-02-23) - -### Bug fixes - -- Fixed a bug where recreating a container multiple times would cause the - new container to be started without the previous volumes. - -- Fixed a bug where Compose would set the value of unset environment variables - to an empty string, instead of a key without a value. - -- Provide a better error message when Compose requires a more recent version - of the Docker API. - -- Add a missing config field `network.aliases` which allows setting a network - scoped alias for a service. - -- Fixed a bug where `run` would not start services listed in `depends_on`. - -- Fixed a bug where `networks` and `network_mode` where not merged when using - extends or multiple Compose files. - -- Fixed a bug with service aliases where the short container id alias was - only contained 10 characters, instead of the 12 characters used in previous - versions. - -- Added a missing log message when creating a new named volume. - -- Fixed a bug where `build.args` was not merged when using `extends` or - multiple Compose files. - -- Fixed some bugs with config validation when null values or incorrect types - were used instead of a mapping. - -- Fixed a bug where a `build` section without a `context` would show a stack - trace instead of a helpful validation message. - -- Improved compatibility with swarm by only setting a container affinity to - the previous instance of a services' container when the service uses an - anonymous container volume. Previously the affinity was always set on all - containers. - -- Fixed the validation of some `driver_opts` would cause an error if a number - was used instead of a string. - -- Some improvements to the `run.sh` script used by the Compose container install - option. - -- Fixed a bug with `up --abort-on-container-exit` where Compose would exit, - but would not stop other containers. - -- Corrected the warning message that is printed when a boolean value is used - as a value in a mapping. - -## 1.6.0 - -(2016-01-15) - -### Major Features - -- Compose 1.6 introduces a new format for `docker-compose.yml` which lets - you define networks and volumes in the Compose file as well as services. It - also makes a few changes to the structure of some configuration options. - - You don't have to use it - your existing Compose files will run on Compose - 1.6 exactly as they do today. - - Check the [upgrade guide](../compose/compose-file/legacy-versions.md) - for full details. - -- Support for networking has exited experimental status and is the recommended - way to enable communication between containers. - - If you use the new file format, your app will use networking. If you aren't - ready yet, just leave your Compose file as it is and it'll continue to work - just the same. - - By default, you don't have to configure any networks. In fact, using - networking with Compose involves even less configuration than using links. - Consult the [networking guide](../compose/networking.md) for how to use it. - - The experimental flags `--x-networking` and `--x-network-driver`, introduced - in Compose 1.5, have been removed. - -- You can now pass arguments to a build if you're using the new file format: - - build: - context: . - args: - buildno: 1 - -- You can now specify both a `build` and an `image` key if you're using the - new file format. `docker-compose build` will build the image and tag it with - the name you've specified, while `docker-compose pull` will attempt to pull - it. - -- There's a new `events` command for monitoring container events from - the application, much like `docker events`. This is a good primitive for - building tools on top of Compose for performing actions when particular - things happen, such as containers starting and stopping. - -- There's a new `depends_on` option for specifying dependencies between - services. This enforces the order of startup, and ensures that when you run - `docker-compose up SERVICE` on a service with dependencies, those are started - as well. - -### New Features - -- Added a new command `config` which validates and prints the Compose - configuration after interpolating variables, resolving relative paths, and - merging multiple files and `extends`. - -- Added a new command `create` for creating containers without starting them. - -- Added a new command `down` to stop and remove all the resources created by - `up` in a single command. - -- Added support for the `cpu_quota` configuration option. - -- Added support for the `stop_signal` configuration option. - -- Commands `start`, `restart`, `pause`, and `unpause` now exit with an - error status code if no containers were modified. - -- Added a new `--abort-on-container-exit` flag to `up` which causes `up` to - stop all container and exit once the first container exits. - -- Removed support for `FIG_FILE`, `FIG_PROJECT_NAME`, and no longer reads - `fig.yml` as a default Compose file location. - -- Removed the `migrate-to-labels` command. - -- Removed the `--allow-insecure-ssl` flag. - -### Bug fixes - -- Fixed a validation bug that prevented the use of a range of ports in - the `expose` field. - -- Fixed a validation bug that prevented the use of arrays in the `entrypoint` - field if they contained duplicate entries. - -- Fixed a bug that caused `ulimits` to be ignored when used with `extends`. - -- Fixed a bug that prevented ipv6 addresses in `extra_hosts`. - -- Fixed a bug that caused `extends` to be ignored when included from - multiple Compose files. - -- Fixed an incorrect warning when a container volume was defined in - the Compose file. - -- Fixed a bug that prevented the force shutdown behavior of `up` and - `logs`. - -- Fixed a bug that caused `None` to be printed as the network driver name - when the default network driver was used. - -- Fixed a bug where using the string form of `dns` or `dns_search` would - cause an error. - -- Fixed a bug where a container would be reported as "Up" when it was - in the restarting state. - -- Fixed a confusing error message when DOCKER_CERT_PATH was not set properly. - -- Fixed a bug where attaching to a container would fail if it was using a - non-standard logging driver (or none at all). - -## 1.5.2 - -(2015-12-03) - -- Fixed a bug which broke the use of `environment` and `env_file` with - `extends`, and caused environment keys without values to have a `None` - value, instead of a value from the host environment. - -- Fixed a regression in 1.5.1 that caused a warning about volumes to be - raised incorrectly when containers were recreated. - -- Fixed a bug which prevented building a `Dockerfile` that used `ADD ` - -- Fixed a bug with `docker-compose restart` which prevented it from - starting stopped containers. - -- Fixed handling of SIGTERM and SIGINT to properly stop containers - -- Add support for using a url as the value of `build` - -- Improved the validation of the `expose` option - -## 1.5.1 - -(2015-11-12) - -- Add the `--force-rm` option to `build`. - -- Add the `ulimit` option for services in the Compose file. - -- Fixed a bug where `up` would error with "service needs to be built" if - a service changed from using `image` to using `build`. - -- Fixed a bug that would cause incorrect output of parallel operations - on some terminals. - -- Fixed a bug that prevented a container from being recreated when the - mode of a `volumes_from` was changed. - -- Fixed a regression in 1.5.0 where non-utf-8 unicode characters would cause - `up` or `logs` to crash. - -- Fixed a regression in 1.5.0 where Compose would use a success exit status - code when a command fails due to an HTTP timeout communicating with the - docker daemon. - -- Fixed a regression in 1.5.0 where `name` was being accepted as a valid - service option which would override the actual name of the service. - -- When using `--x-networking` Compose no longer sets the hostname to the - container name. - -- When using `--x-networking` Compose will only create the default network - if at least one container is using the network. - -- When printings logs during `up` or `logs`, flush the output buffer after - each line to prevent buffering issues from hiding logs. - -- Recreate a container if one of its dependencies is being created. - Previously a container was only recreated if it's dependencies already - existed, but were being recreated as well. - -- Add a warning when a `volume` in the Compose file is being ignored - and masked by a container volume from a previous container. - -- Improve the output of `pull` when run without a tty. - -- When using multiple Compose files, validate each before attempting to merge - them together. Previously invalid files would result in not helpful errors. - -- Allow dashes in keys in the `environment` service option. - -- Improve validation error messages by including the filename as part of the - error message. - -## 1.5.0 - -(2015-11-03) - -### Breaking changes - -With the introduction of variable substitution support in the Compose file, any -Compose file that uses an environment variable (`$VAR` or `${VAR}`) in the `command:` -or `entrypoint:` field will break. - -Previously these values were interpolated inside the container, with a value -from the container environment. In Compose 1.5.0, the values will be -interpolated on the host, with a value from the host environment. - -To migrate a Compose file to 1.5.0, escape the variables with an extra `$` -(ex: `$$VAR` or `$${VAR}`). See -https://github.com/docker/compose/blob/8cc8e61/docs/compose-file.md#variable-substitution - -### Major features - -- Compose is now available for Windows. - -- Environment variables can be used in the Compose file. See - https://github.com/docker/compose/blob/8cc8e61/docs/compose-file.md#variable-substitution - -- Multiple compose files can be specified, allowing you to override - settings in the default Compose file. See - https://github.com/docker/compose/blob/8cc8e61/docs/reference/docker-compose.md - for more details. - -- Compose now produces better error messages when a file contains - invalid configuration. - -- `up` now waits for all services to exit before shutting down, - rather than shutting down as soon as one container exits. - -- Experimental support for the new docker networking system can be - enabled with the `--x-networking` flag. Read more here: - https://github.com/docker/docker/blob/8fee1c20/docs/userguide/dockernetworks.md - -### New features - -- You can now optionally pass a mode to `volumes_from`. For example, - `volumes_from: ["servicename:ro"]`. - -- Since Docker now lets you create volumes with names, you can refer to those - volumes by name in `docker-compose.yml`. For example, - `volumes: ["mydatavolume:/data"]` will mount the volume named - `mydatavolume` at the path `/data` inside the container. - - If the first component of an entry in `volumes` starts with a `.`, `/` or `~`, - it is treated as a path and expansion of relative paths is performed as - necessary. Otherwise, it is treated as a volume name and passed straight - through to Docker. - - Read more on named volumes and volume drivers here: - https://github.com/docker/docker/blob/244d9c33/docs/userguide/dockervolumes.md - -- `docker-compose build --pull` instructs Compose to pull the base image for - each Dockerfile before building. - -- `docker-compose pull --ignore-pull-failures` instructs Compose to continue - if it fails to pull a single service's image, rather than aborting. - -- You can now specify an IPC namespace in `docker-compose.yml` with the `ipc` - option. - -- Containers created by `docker-compose run` can now be named with the - `--name` flag. - -- If you install Compose with pip or use it as a library, it now works with - Python 3. - -- `image` now supports image digests (in addition to ids and tags). For example, - `image: "busybox@sha256:38a203e1986cf79639cfb9b2e1d6e773de84002feea2d4eb006b52004ee8502d"` - -- `ports` now supports ranges of ports. For example, - - ports: - - "3000-3005" - - "9000-9001:8000-8001" - -- `docker-compose run` now supports a `-p|--publish` parameter, much like - `docker run -p`, for publishing specific ports to the host. - -- `docker-compose pause` and `docker-compose unpause` have been implemented, - analogous to `docker pause` and `docker unpause`. - -- When using `extends` to copy configuration from another service in the same - Compose file, you can omit the `file` option. - -- Compose can be installed and run as a Docker image. This is an experimental - feature. - -### Bug fixes - -- All values for the `log_driver` option which are supported by the Docker - daemon are now supported by Compose. - -- `docker-compose build` can now be run successfully against a Swarm cluster. - -## 1.4.2 - -(2015-09-22) - -- Fixed a regression in the 1.4.1 release that would cause `docker-compose up` - without the `-d` option to exit immediately. - -## 1.4.1 - -(2015-09-10) - -### Bug fixes - -- Some configuration changes (notably changes to `links`, `volumes_from`, and - `net`) were not properly triggering a container recreate as part of - `docker-compose up`. -- `docker-compose up ` was showing logs for all services instead of - just the specified services. -- Containers with custom container names were showing up in logs as - `service_number` instead of their custom container name. -- When scaling a service sometimes containers would be recreated even when - the configuration had not changed. - - -## 1.4.0 - -(2015-08-04) - -- By default, `docker-compose up` now only recreates containers for services whose configuration has changed since they were created. This should result in a dramatic speed-up for many applications. - - The experimental `--x-smart-recreate` flag which introduced this feature in Compose 1.3.0 has been removed, and a `--force-recreate` flag has been added for when you want to recreate everything. - -- Several of Compose's commands - `scale`, `stop`, `kill` and `rm` - now perform actions on multiple containers in parallel, rather than in sequence, which will run much faster on larger applications. - -- You can now specify a custom name for a service's container with `container_name`. Because Docker container names must be unique, this means you can't scale the service beyond one container. - -- You no longer have to specify a `file` option when using `extends` - it will default to the current file. - -- Service names can now contain dots, dashes and underscores. - -- Compose can now read YAML configuration from standard input, rather than from a file, by specifying `-` as the filename. This makes it easier to generate configuration dynamically: - - $ echo 'redis: {"image": "redis"}' | docker-compose --file - up - -- There's a new `docker-compose version` command which prints extended information about Compose's bundled dependencies. - -- `docker-compose.yml` now supports `log_opt` as well as `log_driver`, allowing you to pass extra configuration to a service's logging driver. - -- `docker-compose.yml` now supports `memswap_limit`, similar to `docker run --memory-swap`. - -- When mounting volumes with the `volumes` option, you can now pass in any mode supported by the daemon, not just `:ro` or `:rw`. For example, SELinux users can pass `:z` or `:Z`. - -- You can now specify a custom volume driver with the `volume_driver` option in `docker-compose.yml`, much like `docker run --volume-driver`. - -- A bug has been fixed where Compose would fail to pull images from private registries serving plain (unsecured) HTTP. The `--allow-insecure-ssl` flag, which was previously used to work around this issue, has been deprecated and now has no effect. - -- A bug has been fixed where `docker-compose build` would fail if the build depended on a private Hub image or an image from a private registry. - -- A bug has been fixed where Compose would crash if there were containers which the Docker daemon had not finished removing. - -- Two bugs have been fixed where Compose would sometimes fail with a "Duplicate bind mount" error, or fail to attach volumes to a container, if there was a volume path specified in `docker-compose.yml` with a trailing slash. - -Thanks @mnowster, @dnephin, @ekristen, @funkyfuture, @jeffk and @lukemarsden! - -## 1.3.3 - -(2015-07-15) - -### Regression fixes - -- When stopping containers gracefully, Compose was setting the timeout to 0, effectively forcing a SIGKILL every time. -- Compose would sometimes crash depending on the formatting of container data returned from the Docker API. - -## 1.3.2 - -(2015-07-14) - -### Bug fixes - -- When there were one-off containers created by running `docker-compose run` on an older version of Compose, `docker-compose run` would fail with a name collision. Compose now shows an error if you have leftover containers of this type lying around, and tells you how to remove them. -- Compose was not reading Docker authentication config files created in the new location, `~/docker/config.json`, and authentication against private registries would therefore fail. -- When a container had a pseudo-TTY attached, its output in `docker-compose up` would be truncated. -- `docker-compose up --x-smart-recreate` would sometimes fail when an image tag was updated. -- `docker-compose up` would sometimes create two containers with the same numeric suffix. -- `docker-compose rm` and `docker-compose ps` would sometimes list services that aren't part of the current project (though no containers were erroneously removed). -- Some `docker-compose` commands would not show an error if invalid service names were passed in. - -Thanks @dano, @josephpage, @kevinsimper, @lieryan, @phemmer, @soulrebel and @sschepens! - -## 1.3.1 - -(2015-06-21) - -### Bug fixes - -- `docker-compose build` would always attempt to pull the base image before building. -- `docker-compose help migrate-to-labels` failed with an error. -- If no network mode was specified, Compose would set it to "bridge", rather than allowing the Docker daemon to use its configured default network mode. - -## 1.3.0 - -(2015-06-18) - -### Important notes - -- **This release contains breaking changes, and you will need to either remove or migrate your existing containers before running your app** - see the [upgrading section of the install docs](https://github.com/docker/compose/blob/1.3.0rc1/docs/install.md#upgrading) for details. - -- Compose now requires Docker 1.6.0 or later. - -### Improvements - -- Compose now uses container labels, rather than names, to keep track of containers. This makes Compose both faster and easier to integrate with your own tools. - -- Compose no longer uses "intermediate containers" when recreating containers for a service. This makes `docker-compose up` less complex and more resilient to failure. - -### New features - -- `docker-compose up` has an **experimental** new behavior: it will only recreate containers for services whose configuration has changed in `docker-compose.yml`. This will eventually become the default, but for now you can take it for a spin: - - $ docker-compose up --x-smart-recreate - -- When invoked in a subdirectory of a project, `docker-compose` will now climb up through parent directories until it finds a `docker-compose.yml`. - -Several new configuration keys have been added to `docker-compose.yml`: - -- `dockerfile`, like `docker build --file`, lets you specify an alternate Dockerfile to use with `build`. -- `labels`, like `docker run --labels`, lets you add custom metadata to containers. -- `extra_hosts`, like `docker run --add-host`, lets you add entries to a container's `/etc/hosts` file. -- `pid: host`, like `docker run --pid=host`, lets you reuse the same PID namespace as the host machine. -- `cpuset`, like `docker run --cpuset-cpus`, lets you specify which CPUs to allow execution in. -- `read_only`, like `docker run --read-only`, lets you mount a container's filesystem as read-only. -- `security_opt`, like `docker run --security-opt`, lets you specify [security options](/reference/cli/docker/container/run/#security-opt). -- `log_driver`, like `docker run --log-driver`, lets you specify a [log driver](/reference/cli/docker/container/run/#log-driver). - -### Bug fixes - -- The output of `docker-compose run` was sometimes truncated, especially when running under Jenkins. -- A service's volumes would sometimes not update after volume configuration was changed in `docker-compose.yml`. -- Authenticating against third-party registries would sometimes fail. -- `docker-compose run --rm` would fail to remove the container if the service had a `restart` policy in place. -- `docker-compose scale` would refuse to scale a service beyond 1 container if it exposed a specific port number on the host. -- Compose would refuse to create multiple volume entries with the same host path. - -Thanks @ahromis, @albers, @aleksandr-vin, @antoineco, @ccverak, @chernjie, @dnephin, @edmorley, @fordhurley, @josephpage, @KyleJamesWalker, @lsowen, @mchasal, @noironetworks, @sdake, @sdurrheimer, @sherter, @stephenlawrence, @thaJeztah, @thieman, @turtlemonvh, @twhiteman, @vdemeester, @xuxinkun and @zwily! - -## 1.2.0 - -(2015-04-16) - -- `docker-compose.yml` now supports an `extends` option, which enables a service to inherit configuration from another service in another configuration file. This is really good for sharing common configuration between apps, or for configuring the same app for different environments. Here's the [documentation](https://github.com/docker/compose/blob/master/docs/). - -- When using Compose with a Swarm cluster, containers that depend on one another will be co-scheduled on the same node. This means that most Compose apps will now work out of the box, as long as they don't use `build`. - -- Repeated invocations of `docker-compose up` when using Compose with a Swarm cluster now work reliably. - -- Directories passed to `build`, filenames passed to `env_file` and volume host paths passed to `volumes` are now treated as relative to the *directory of the configuration file*, not the directory that `docker-compose` is being run in. In the majority of cases, those are the same, but if you use the `-f|--file` argument to specify a configuration file in another directory, **this is a breaking change**. - -- A service can now share another service's network namespace with `net: container:`. - -- `volumes_from` and `net: container:` entries are taken into account when resolving dependencies, so `docker-compose up ` will correctly start all dependencies of ``. - -- `docker-compose run` now accepts a `--user` argument to specify a user to run the command as, just like `docker run`. - -- The `up`, `stop` and `restart` commands now accept a `--timeout` (or `-t`) argument to specify how long to wait when attempting to gracefully stop containers, just like `docker stop`. - -- `docker-compose rm` now accepts `-f` as a shorthand for `--force`, just like `docker rm`. - -Thanks, @abesto, @albers, @alunduil, @dnephin, @funkyfuture, @gilclark, @IanVS, @KingsleyKelly, @knutwalker, @thaJeztah and @vmalloc! - -## 1.1.0 - -(2015-02-25) - -Fig has been renamed to Docker Compose, or just Compose for short. This has several implications for you: - -- The command you type is now `docker-compose`, not `fig`. -- You should rename your fig.yml to docker-compose.yml. -- If you’re installing via PyPI, the package is now `docker-compose`, so install it with `pip install docker-compose`. - -Besides that, there’s a lot of new stuff in this release: - -- We’ve made a few small changes to ensure that Compose will work with Swarm, Docker’s new clustering tool (https://github.com/docker/swarm). Eventually you'll be able to point Compose at a Swarm cluster instead of a standalone Docker host and it’ll run your containers on the cluster with no extra work from you. As Swarm is still developing, integration is rough and lots of Compose features don't work yet. - -- `docker-compose run` now has a `--service-ports` flag for exposing ports on the given service. This is useful for running your webapp with an interactive debugger, for example. - -- You can now link to containers outside your app with the `external_links` option in docker-compose.yml. - -- You can now prevent `docker-compose up` from automatically building images with the `--no-build` option. This will make fewer API calls and run faster. - -- If you don’t specify a tag when using the `image` key, Compose will default to the `latest` tag, rather than pulling all tags. - -- `docker-compose kill` now supports the `-s` flag, allowing you to specify the exact signal you want to send to a service’s containers. - -- docker-compose.yml now has an `env_file` key, analogous to `docker run --env-file`, letting you specify multiple environment variables in a separate file. This is great if you have a lot of them, or if you want to keep sensitive information out of version control. - -- docker-compose.yml now supports the `dns_search`, `cap_add`, `cap_drop`, `cpu_shares` and `restart` options, analogous to `docker run`’s `--dns-search`, `--cap-add`, `--cap-drop`, `--cpu-shares` and `--restart` options. - -- Compose now ships with Bash tab completion - see the installation and usage docs at https://github.com/docker/compose/blob/1.1.0/docs/completion.md - -- A number of bugs have been fixed - see the milestone for details: https://github.com/docker/compose/issues?q=milestone%3A1.1.0+ - -Thanks @dnephin, @squebe, @jbalonso, @raulcd, @benlangfield, @albers, @ggtools, @bersace, @dtenenba, @petercv, @drewkett, @TFenby, @paulRbr, @Aigeruth and @salehe! - -## 1.0.1 - -(2014-11-04) - - - Added an `--allow-insecure-ssl` option to allow `fig up`, `fig run` and `fig pull` to pull from insecure registries. - - Fixed `fig run` not showing output in Jenkins. - - Fixed a bug where Fig couldn't build Dockerfiles with ADD statements pointing at URLs. - -## 1.0.0 - -(2014-10-16) - -The highlights: - - - [Fig has joined Docker.](https://www.orchardup.com/blog/orchard-is-joining-docker) Fig will continue to be maintained, but we'll also be incorporating the best bits of Fig into Docker itself. - - This means the GitHub repository has moved to [https://github.com/docker/fig](https://github.com/docker/fig) and our IRC channel is now #docker-fig on Freenode. - - - Fig can be used with the [official Docker OS X installer](../desktop/install/mac-install.md). Boot2Docker will mount the home directory from your host machine so volumes work as expected. - - - Fig supports Docker 1.3. - - - It is now possible to connect to the Docker daemon using TLS by using the `DOCKER_CERT_PATH` and `DOCKER_TLS_VERIFY` environment variables. - - - There is a new `fig port` command which outputs the host port binding of a service, in a similar way to `docker port`. - - - There is a new `fig pull` command which pulls the latest images for a service. - - - There is a new `fig restart` command which restarts a service's containers. - - - Fig creates multiple containers in service by appending a number to the service name. For example, `db_1`, `db_2`. As a convenience, Fig will now give the first container an alias of the service name. For example, `db`. - - This link alias is also a valid hostname and added to `/etc/hosts` so you can connect to linked services using their hostname. For example, instead of resolving the environment variables `DB_PORT_5432_TCP_ADDR` and `DB_PORT_5432_TCP_PORT`, you could just use the hostname `db` and port `5432` directly. - - - Volume definitions now support `ro` mode, expanding `~` and expanding environment variables. - - - `.dockerignore` is supported when building. - - - The project name can be set with the `FIG_PROJECT_NAME` environment variable. - - - The `--env` and `--entrypoint` options have been added to `fig run`. - - - The Fig binary for Linux is now linked against an older version of glibc so it works on CentOS 6 and Debian Wheezy. - -Other things: - - - `fig ps` now works on Jenkins and makes fewer API calls to the Docker daemon. - - `--verbose` displays more useful debugging output. - - When starting a service where `volumes_from` points to a service without any containers running, that service will now be started. - - Lots of docs improvements. Notably, environment variables are documented and official repositories are used throughout. - -Thanks @dnephin, @d11wtq, @marksteve, @rubbish, @jbalonso, @timfreund, @alunduil, @mieciu, @shuron, @moss, @suzaku and @chmouel!

Such a -configuration doesn't work within a Docker container. The Docker container uses -its own network namespace, and resolves loopback addresses such as `127.0.0.1` -to itself, and it's unlikely to be running a DNS server on its own loopback -address. - -If Docker detects that no DNS server referenced in `/etc/resolv.conf` is a fully -functional DNS server, the following warning occurs: - -```text -WARNING: Local (127.0.0.1) DNS resolver found in resolv.conf and containers -can't use it.

It can be built with a simple HTML -file, some vanilla Javascript or any frontend framework, such as React or Vue.js. - -When Docker Desktop installs the extension, it extracts the UI folder from the extension image, as defined by the -`ui` section in the `metadata.json`. See the [ui metadata section](./metadata.md#ui-section) for more details. - -Every time users click on the **Extensions** tab, Docker Desktop initializes the extension's UI as if it was the first time. When they navigate away from the tab, both the UI itself and all the sub-processes started by it (if any) are terminated. - -The frontend can invoke `docker` commands, communicate with the extension backend, or invoke extension executables -deployed on the host, through the [Extensions SDK](https://www.npmjs.com/package/@docker/extension-api-client). - -> **Tip** -> -> The `docker extension init` generates a React based extension. But you can still use it as a starting point for -> your own extension and use any other frontend framework, like Vue, Angular, Svelte, etc. or event stay with -> vanilla Javascript. -{ .tip } - -Learn more about [building a frontend](../build/frontend-extension-tutorial.md) for your extension. - -## The backend - -Alongside a frontend application, extensions can also contain one or many backend services. In most cases, the Extension does not need a backend, and features can be implemented just by invoking docker commands through the SDK. However, there are some cases when an extension requires a backend - service, for example: -- To run long-running processes that must outlive the frontend -- To store data in a local database and serve them back with a REST API -- To store the extension state, like when a button starts a long-running process, so that if you navigate away - from the extension and come back, the frontend can pick up where it left off -- To access specific resources in the Docker Desktop VM, for example by mounting folders in the compose -file - -> **Tip** -> -> The `docker extension init` generates a Go backend. But you can still use it as a starting point for -> your own extension and use any other language like Node.js, Python, Java, .Net, or any other language and framework. -{ .tip } - -Usually, the backend is made of one container that runs within the Docker Desktop VM. Internally, Docker Desktop creates -a Docker Compose project, creates the container from the `image` option of the `vm` section of the `metadata.json`, and -attaches it to the Compose project. See the [ui metadata section](./metadata.md#vm-section) for more details. - -In some cases, a `compose.yml` file can be used instead of an `image`. This is useful when the backend container -needs more specific options, such as mounting volumes or requesting [capabilities](https://docs.docker.com/engine/reference/run/#runtime-privilege-and-linux-capabilities) -that can't be expressed just with a Docker image. The `compose.yml` file can also be used to add multiple containers -needed by the extension, like a database or a message broker. -Note that, if the Compose file defines many services, the SDK can only contact the first of them. - -> **Note** -> -> In some cases, it is useful to also interact with the Docker engine from the backend. -> See [How to use the Docker socket](../guides/use-docker-socket-from-backend.md) from the backend. - -To communicate with the backend, the Extension SDK provides [functions](../dev/api/backend.md#get) to make `GET`, -`POST`, `PUT`, `HEAD`, and `DELETE` requests from the frontend. Under the hood, the communication is done through a socket -or named pipe, depending on the operating system. If the backend was listening to a port, it would be difficult to -prevent collision with other applications running on the host or in a container already. Also, some users are -running Docker Desktop in constrained environments where they can't open ports on their machines. - -![Backend and frontend communication](./images/extensions-arch-2.png?w=500h=300) - -Finally, the backend can be built with any technology, as long as it can run in a container and listen on a socket. - -Learn more about [adding a backend](../build/backend-extension-tutorial.md) to your extension. - -## Executables - -In addition to the frontend and the backend, extensions can also contain executables. Executables are binaries or shell scripts -that are installed on the host when the extension is installed. The frontend can invoke them with [the extension SDK](../dev/api/backend.md#invoke-an-extension-binary-on-the-host). - -These executables are useful when the extension needs to interact with a third-party CLI tool, like AWS, `kubectl`, etc. -Shipping those executables with the extension ensure that the CLI tool is always available, at the right version, on -the users' machine. - -When Docker Desktop installs the extension, it copies the executables on the host as defined by the `host` section in -the `metadata.json`. See the [ui metadata section](./metadata.md#host-section) for more details. - -![Executable and frontend communication](./images/extensions-arch-3.png?w=250h=300) - -However, since they're executed on the users' machine, they have to be available to the platform they're running on. -For example, if you want to ship the `kubectl` executable, you need to provide a different version for Windows, Mac, -and Linux.

This is possible, but highly discouraged. It means that: - -- You'll need to manually replicate the look and feel of Docker Desktop. This takes a lot of effort, and if you don't match our theme closely enough, users will find your extension jarring and we may ask you to make changes during a review process. -- You'll have a higher maintenance burden. Whenever Docker Desktop's theme changes (which could happen in any release), you'll need to manually change your extension to match it. -- If your extension is open-source, deliberately avoiding common conventions will make it harder for the community to contribute to it. - -## Step two: Follow the below recommendations - -### Follow our MUI best practices (if applicable) - -See our [MUI best practices](mui-best-practices.md) article. - -### Only use colors from our palette - -With minor exceptions, displaying your logo for example, you should only use colors from our palette.

To ensure that Docker Desktop provides a consistent experience across platforms. - - During research, the most frequently cited reason for users wanting Docker Desktop for Linux was to ensure a consistent Docker Desktop - experience with feature parity across all major operating systems. Utilizing - a VM ensures that the Docker Desktop experience for Linux users will closely - match that of Windows and macOS. - -2. To make use of new kernel features. - - Sometimes we want to make use of new operating system features. Because we control the kernel and the OS inside the VM, we can roll these out to all users immediately, even to users who are intentionally sticking on an LTS version of their machine OS. - -3. To enhance security. - - Container image vulnerabilities pose a security risk for the host environment. There is a large number of unofficial images that are not guaranteed to be verified for known vulnerabilities. Malicious users can push images to public registries and use different methods to trick users into pulling and running them. The VM approach mitigates this threat as any malware that gains root privileges is restricted to the VM environment without access to the host. - - Why not run rootless Docker? Although this has the benefit of superficially limiting access to the root user so everything looks safer in "top", it allows unprivileged users to gain `CAP_SYS_ADMIN` in their own user namespace and access kernel APIs which are not expecting to be used by unprivileged users, resulting in [vulnerabilities](https://www.openwall.com/lists/oss-security/2022/01/18/7). - -4. To provide the benefits of feature parity and enhanced security, with minimal impact on performance. - - The VM utilized by Docker Desktop for Linux uses [`VirtioFS`](https://virtio-fs.gitlab.io), a shared file system that allows virtual machines to access a directory tree located on the host. Our internal benchmarking shows that with the right resource allocation to the VM, near native file system performance can be achieved with VirtioFS. - - As such, we have adjusted the default memory available to the VM in Docker Desktop for Linux. You can tweak this setting to your specific needs by using the **Memory** slider within the **Settings** > **Resources** tab of Docker Desktop. - -### How do I enable file sharing? - -Docker Desktop for Linux uses [VirtioFS](https://virtio-fs.gitlab.io/) as the -default (and currently only) mechanism to enable file sharing between the host -and Docker Desktop VM. In order not to require elevated privileges, without -unnecessarily restricting operations on the shared files, Docker Desktop runs -the file sharing service (`virtiofsd`) inside a user namespace (see -`user_namespaces(7)`) with UID and GID mapping configured. As a result Docker -Desktop relies on the host being configured to enable the current user to use -subordinate ID delegation. For this to be true `/etc/subuid` (see `subuid(5)`) -and `/etc/subgid` (see `subgid(5)`) must be present. Docker Desktop only -supports subordinate ID delegation configured via files. Docker Desktop maps the -current user ID and GID to 0 in the containers. It uses the first entry -corresponding to the current user in `/etc/subuid` and `/etc/subgid` to set up -mappings for IDs above 0 in the containers. - -| ID in container | ID on host | -| --------------- | -------------------------------------------------------------------------------- | -| 0 (root) | ID of the user running DD (e.g. 1000) | -| 1 | 0 + beginning of ID range specified in `/etc/subuid`/`/etc/subgid` (e.g. 100000) | -| 2 | 1 + beginning of ID range specified in `/etc/subuid`/`/etc/subgid` (e.g. 100001) | -| 3 | 2 + beginning of ID range specified in `/etc/subuid`/`/etc/subgid` (e.g. 100002) | -| ... | ... | - -If `/etc/subuid` and `/etc/subgid` are missing, they need to be created. -Both should contain entries in the form - -`::`. For example, to allow the current user -to use IDs from 100 000 to 165 535: - -```console -$ grep "$USER" /etc/subuid >> /dev/null 2&>1 || (echo "$USER:100000:65536" | sudo tee -a /etc/subuid) -$ grep "$USER" /etc/subgid >> /dev/null 2&>1 || (echo "$USER:100000:65536" | sudo tee -a /etc/subgid) -``` - -To verify the configs have been created correctly, inspect their contents: - -```console -$ echo $USER -exampleuser -$ cat /etc/subuid -exampleuser:100000:65536 -$ cat /etc/subgid -exampleuser:100000:65536 -``` - -In this scenario if a shared file is `chown`ed inside a Docker Desktop container -owned by a user with a UID of 1000, it shows up on the host as owned by -a user with a UID of 100999. This has the unfortunate side effect of preventing -easy access to such a file on the host. The problem is resolved by creating -a group with the new GID and adding our user to it, or by setting a recursive -ACL (see `setfacl(1)`) for folders shared with the Docker Desktop VM. - -### Where does Docker Desktop store Linux containers? - -Docker Desktop stores Linux containers and images in a single, large "disk image" file in the Linux filesystem. This is different from Docker on Linux, which usually stores containers and images in the `/var/lib/docker` directory on the host's filesystem. - -#### Where is the disk image file? - -To locate the disk image file, select **Settings** from the Docker Dashboard then **Advanced** from the **Resources** tab. - -The **Advanced** tab displays the location of the disk image. It also displays the maximum size of the disk image and the actual space the disk image is consuming. Note that other tools might display space usage of the file in terms of the maximum file size, and not the actual file size. - -##### What if the file is too large? - -If the disk image file is too large, you can: - -- Move it to a bigger drive -- Delete unnecessary containers and images -- Reduce the maximum allowable size of the file - -##### How do I move the file to a bigger drive? - -To move the disk image file to a different location: - -1. Select **Settings** then **Advanced** from the **Resources** tab. - -2. In the **Disk image location** section, select **Browse** and choose a new location for the disk image. - -3. Select **Apply & Restart** for the changes to take effect. - -Do not move the file directly in Finder as this can cause Docker Desktop to lose track of the file. - -##### How do I delete unnecessary containers and images? - -Check whether you have any unnecessary containers and images. If your client and daemon API are running version 1.25 or later (use the `docker version` command on the client to check your client and daemon API versions), you can see the detailed space usage information by running: - -```console -$ docker system df -v -``` - -Alternatively, to list images, run: - -```console -$ docker image ls -``` - -To list containers, run: - -```console -$ docker container ls -a -``` - -If there are lots of redundant objects, run the command: - -```console -$ docker system prune -``` - -This command removes all stopped containers, unused networks, dangling images, and build cache. - -It might take a few minutes to reclaim space on the host depending on the format of the disk image file: - -- If the file is named `Docker.raw`: space on the host should be reclaimed within a few seconds. -- If the file is named `Docker.qcow2`: space will be freed by a background process after a few minutes. - -Space is only freed when images are deleted. Space is not freed automatically when files are deleted inside running containers. To trigger a space reclamation at any point, run the command: - -```console -$ docker run --privileged --pid=host docker/desktop-reclaim-space -``` - -Note that many tools report the maximum file size, not the actual file size. -To query the actual size of the file on the host from a terminal, run: - -```console -$ cd ~/.docker/desktop/vms/0/data -$ ls -klsh Docker.raw -2333548 -rw-r--r--@ 1 username staff 64G Dec 13 17:42 Docker.raw -``` - -In this example, the actual size of the disk is `2333548` KB, whereas the maximum size of the disk is `64` GB. - -##### How do I reduce the maximum size of the file? - -To reduce the maximum size of the disk image file: - -1. From Docker Dashboard select **Settings** then **Advanced** from the **Resources** tab. - -2. The **Disk image size** section contains a slider that allows you to change the maximum size of the disk image. Adjust the slider to set a lower limit. - -3. Select **Apply & Restart**. - -When you reduce the maximum size, the current disk image file is deleted, and therefore, all containers and images are lost. diff --git a/content/desktop/feedback.md b/content/desktop/feedback.md deleted file mode 100644 index 4ff38f7f09bb..000000000000 --- a/content/desktop/feedback.md +++ /dev/null @@ -1,47 +0,0 @@ ---- -description: Find a way to provide feedback that's right for you -keywords: Feedback, Docker Desktop, Linux, Mac, Windows, Dev Environments, Extensions, - Community forum, bugs, problems, issues -title: Give feedback ---- - -There are many ways you can provide feedback on Docker Desktop or Docker Desktop features. - -### In-product feedback - -On each Docker Dashboard view, there is a **Give feedback** link.

For example, reduced Linux Capabilities, Seccomp, AppArmor. - -### Who is it for? - -- For organizations and developers that want to prevent container attacks and reduce vulnerabilities in developer environments. -- For organizations that want to ensure stronger container isolation that is easy and intuitive to implement on developers' machines. - -### What happens when Enhanced Container Isolation is turned on? - -When Enhanced Container Isolation is turned on, the following features are enabled: - -- All user containers are automatically run in Linux User Namespaces which ensures stronger isolation. Each container runs in a dedicated Linux user-namespace. -- The root user in the container maps to an unprivileged user inside the Docker Desktop Linux VM. -- Containers become harder to breach. For example, sensitive system calls are vetted and portions of `/proc` and `/sys` are emulated. -- Users can continue using containers as usual, including bind mounting host directories, volumes, etc. -- No change in the way developers run containers, and no special container images are required. -- Privileged containers (e.g., `--privileged` flag) work, but they are only privileged within the container's Linux User Namespace, not in the Docker Desktop VM. Therefore they can't be used to breach the Docker Desktop VM. -- Docker-in-Docker and even Kubernetes-in-Docker works, but run unprivileged inside the Docker Desktop Linux VM. - -In addition, the following restrictions are imposed: - -- Containers can no longer share namespaces with the Docker Desktop VM (e.g., `--network=host`, `--pid=host` are disallowed). -- Containers can no longer modify configuration files inside the Docker Desktop VM (e.g., mounting any VM directory into the container is disallowed). -- Containers can no longer access the Docker engine (e.g., mounting the Docker engine's socket into the container is restricted); this prevents malicious containers from gaining control of the Docker engine. Admins can relax this for [trusted container images](config.md). -- Console access to the Docker Desktop VM is forbidden for all users. - -These features and restrictions ensure that containers are better secured at runtime, with minimal impact to developer experience and productivity. - -For more information on how Enhanced Container Isolation work, see [How does it work](how-eci-works.md). - -> **Important** -> -> Enhanced Container Isolation does not yet fully protect Docker builds, -> Kubernetes pods and Extension containers.

Ensure your organization has a Docker Business subscription. -2. Log in to your organization in Docker Desktop. This will ensure the ECI feature is available to you in Docker Desktop's Settings menu. -3. Stop and remove all existing containers. -4. Navigate to **Settings** > **General** in Docker Desktop. -5.

Select **Apply and restart** to save your settings. - -> **Important** -> -> Enhanced Container Isolation does not protect containers created prior to enabling ECI. For more information on known limitations and workarounds, see [FAQs](faq.md). -{ .important } - -#### As an admin - -To enable Enhanced Container Isolation as an admin, you first need to [configure a `registry.json` file to enforce sign-in](../../../security/for-admins/configure-sign-in.md). -This is because the Enhanced Container Isolation feature requires a Docker -Business subscription and therefore your Docker Desktop users must authenticate -to your organization for this configuration to take effect. - -Next, you must [create and configure the `admin-settings.json` file](../settings-management/configure.md) and specify: - -```json -{ - "configurationFileVersion": 2, - "enhancedContainerIsolation": { - "value": true, - "locked": true - } -} -``` - -By setting `"value": true`, the admin ensures ECI is enabled by default. By -setting `"locked": true`, the admin ensures ECI can't be disabled by -developers. If you wish to give developers the ability to disable the feature, -set `"locked": false`. - -In addition, starting with Docker Desktop 4.27, admins can also configure Docker -socket mount permissions for containers, as described [here](config.md). - -For this to take effect: - -- On a new install, developers need to launch Docker Desktop and authenticate to their organization. -- On an existing install, developers need to quit Docker Desktop through the Docker menu, and then relaunch Docker Desktop. If they are already signed in, they don’t need to sign in again for the changes to take effect. - -> **Important** -> -> Selecting **Restart** from the Docker menu isn't enough as it only restarts some components of Docker Desktop. -{ .important } - -### What do users see when this setting is enforced by an admin? - -When Enhanced Container Isolation is enabled, users see: -- **Use Enhanced Container Isolation** toggled on in **Settings** > **General**. -- Containers run within a Linux user namespace. - -To check, run: - -```console -$ docker run --rm alpine cat /proc/self/uid_map -``` - -The following output displays: - -```text - 0 100000 65536 -``` - -This indicates that the container's root user (0) maps to unprivileged user -(100000) in the Docker Desktop VM, and that the mapping extends for a range of -64K user-IDs.

These are -described below. - -### Image list - -The `imageList` is a list of container images that are allowed to bind-mount the -Docker socket. By default the list is empty (i.e., no containers are allowed to -bind-mount the Docker socket when ECI is enabled). However, an admin can add -images to the list, using either of these formats: - -| Image Reference Format | Description | -| :---------------------- | :---------- | -| `[:]` | Name of the image, with optional tag. If the tag is omitted, the `:latest` tag is used. If the tag is the wildcard `*`, then it means "any tag for that image." | -| `@` | Name of the image, with a specific repository digest (e.g., as reported by `docker buildx imagetools inspect `). This means only the image that matches that name and digest is allowed. | - -The image name follows the standard convention, so it can point to any registry -and repository. - -In the example above, the image list was configured with three images: - -```json -"imageList": { - "images": [ - "docker.io/localstack/localstack:*", - "docker.io/testcontainers/ryuk:*", - "docker:cli" - ] -} -``` - -This means that containers that use either the `docker.io/localstack/localstack` -or the `docker.io/testcontainers/ryuk` image (with any tag), or the `docker:cli` -image, are allowed to bind-mount the Docker socket when ECI is enabled. Thus, -the following works: - -```console -$ docker run -it -v /var/run/docker.sock:/var/run/docker.sock docker:cli sh -/ # -``` - -> **Tip** -> -> Be restrictive on the images you allow, as described in [Recommendations](#recommendations) below. -{ .tip } - -In general, it's easier to specify the image using the tag wildcard format -(e.g., `:*`) because then `imageList` doesn't need to be updated whenever a new version of the -image is used. Alternatively, you can use an immutable tag (e.g., `:latest`), -but it does not always work as well as the wildcard because, for example, -Testcontainers uses specific versions of the image, not necessarily the latest -one. - -When ECI is enabled, Docker Desktop periodically downloads the image digests -for the allowed images from the appropriate registry and stores them in -memory. Then, when a container is started with a Docker socket bind-mount, -Docker Desktop checks if the container's image digest matches one of the allowed -digests. If so, the container is allowed to start, otherwise it's blocked. - -Note that due to the digest comparison mentioned in the prior paragraph, it's -not possible to bypass the Docker socket mount permissions by retagging a -disallowed image to the name of an allowed one. In other words, if a user -does: - -```console -$ docker image rm -$ docker tag -$ docker run -v /var/run/docker.sock:/var/run/docker.sock -``` - -then the tag operation succeeds, but the `docker run` command fails -because the image digest of the disallowed image won't match that of the allowed -ones in the repository. - -### Command list - -The `commandList` restricts the Docker commands that a container can issue via a -bind-mounted Docker socket when ECI is enabled. It acts as a complementary -security mechanism to the `imageList` (i.e., like a second line of defense). - -For example, say the `imageList` is configured to allow -image `docker:cli` to mount the Docker socket, and a container is started with -it: - -```console -$ docker run -it --rm -v /var/run/docker.sock:/var/run/docker.sock sh -/ # -``` - -By default, this allows the container to issue any command via that Docker -socket (e.g., build and push images to the organisation's repositories), which -is generally not desirable. - -To improve security, the `commandList` can be configured to restrict the -commands that the processes inside the container can issue on the bind-mounted -Docker socket. The `commandList` can be configured as a "deny" list (default) or -an "allow" list, depending on your preference. - -Each command in the list is specified by its name, as reported by `docker ---help` (e.g., "ps", "build", "pull", "push", etc.) In addition, the following -command wildcards are allowed to block an entire group of commands: - -| Command wildcard | Description | -| :---------------- | :---------- | -| "container\*" | Refers to all "docker container ..." commands | -| "image\*" | Refers to all "docker image ..." commands | -| "volume\*" | Refers to all "docker volume ..." commands | -| "network\*" | Refers to all "docker network ..." commands | -| "build\*" | Refers to all "docker build ..." commands | -| "system\*" | Refers to all "docker system ..." commands | - -For example, the following configuration blocks the `build` and `push` commands -on the Docker socket: - -```json -"commandList": { - "type": "deny", - "commands": ["build", "push"] -} -``` - -Thus, if inside the container, you issue either of those commands on the -bind-mounted Docker socket, they will be blocked: - -```console -/ # docker push myimage -Error response from daemon: enhanced container isolation: docker command "/v1.43/images/myimage/push?tag=latest" is blocked; if you wish to allow it, configure the docker socket command list in the Docker Desktop settings or admin-settings. -``` - -Similarly: - -```console -/ # curl --unix-socket /var/run/docker.sock -XPOST http://localhost/v1.43/images/myimage/push?tag=latest -Error response from daemon: enhanced container isolation: docker command "/v1.43/images/myimage/push?tag=latest" is blocked; if you wish to allow it, configure the docker socket command list in the Docker Desktop settings or admin-settings. -``` - -Note that if the `commandList` had been configured as an "allow" list, then the -effect would be the opposite: only the listed commands would have been allowed. -Whether to configure the list as an allow or deny list depends on the use case. - -### Recommendations - -* Be restrictive on the list of container images for which you allow bind-mounting - of the Docker socket (i.e., the `imageList`). Generally, only allow this for - images that are absolutely needed and that you trust. - -* Use the tag wildcard format if possible in the `imageList` - (e.g., `:*`), as this eliminates the need to update the - `admin-settings.json` file due to image tag changes. - -* In the `commandList`, block commands that you don't expect the container to - execute. For example, for local testing (e.g., Testcontainers), containers that bind-mount the Docker - socket typically create / run / remove containers, volumes, and networks, but - don't typically build images or push them into repositories (though some may - legitimately do this). What commands to allow or block depends on the use case. - - - Note that all "docker" commands issued by the container via the bind-mounted - Docker socket will also execute under enhanced container isolation (i.e., - the resulting container uses a the Linux user-namespace, sensitive system - calls are vetted, etc.) - -### Caveats and limitations - -* When Docker Desktop is restarted, it's possible that an image that is allowed - to mount the Docker socket is unexpectedly blocked from doing so. This can - happen when the image digest changes in the remote repository (e.g., a - ":latest" image was updated) and the local copy of that image (e.g., from a - prior `docker pull`) no longer matches the digest in the remote repository. In - this case, remove the local image and pull it again (e.g., `docker rm ` - and `docker pull `). - -* It's not possible to allow Docker socket bind-mounts on images that are not on - a registry (e.g., images built locally and not yet pushed to a - registry). That's because Docker Desktop pulls the digests for the allowed - images from the registry, and then uses that to compare against the local copy - of the image. - -* The `commandList` configuration applies to all containers that are allowed to - bind-mount the Docker socket. Therefore it can't be configured differently per - container. - -* The following commands are not yet supported in the `commandList`: - -| Unsupported command | Description | -| :------------------- | :---------- | -| compose | Docker compose | -| dev | Docker dev environments | -| extension | Manages Docker extensions | -| feedback | Send feedback to Docker | -| init | Creates Docker-related starter files | -| manifest | Manages Docker image manifests | -| plugins | Manages plugins | -| sbom | View Software Bill of Materials (SBOM) | -| scan | Docker Scan | -| scout | Docker Scout | -| trust | Manage trust on Docker images | - -> **Note** -> -> Docker socket mount permissions do not apply when running "true" -> Docker-in-Docker (i.e., when running the Docker Engine inside a container).

See [Docker socket mount permissions](config.md#docker-socket-mount-permissions). - -### Vetting sensitive system calls - -Another feature of Enhanced Container Isolation is that it intercepts and vets a -few highly sensitive system calls inside containers, such as `mount` and -`umount`. This ensures that processes that have capabilities to execute these -system calls can't use them to breach the container. - -For example, a container that has `CAP_SYS_ADMIN` (required to execute the -`mount` system call) can't use that capability to change a read-only bind mount -into a read-write mount: - -```console -$ docker run -it --rm --cap-add SYS_ADMIN -v $HOME:/mnt:ro alpine -/ # mount -o remount,rw /mnt /mnt -mount: permission denied (are you root?) -``` - -Since the `$HOME` directory was mounted into the container's `/mnt` directory as -read-only, it can't be changed from within the container to read-write, even if the container process has the capability to do so. This -ensures container processes can't use `mount`, or `umount`, to breach the container's -root filesystem. - -Note however that in the example above the container can still create mounts -within the container, and mount them read-only or read-write as needed. Those -mounts are allowed since they occur within the container, and therefore don't -breach it's root filesystem: - -```text -/ # mkdir /root/tmpfs -/ # mount -t tmpfs tmpfs /root/tmpfs -/ # mount -o remount,ro /root/tmpfs /root/tmpfs - -/ # findmnt | grep tmpfs -├─/root/tmpfs tmpfs tmpfs ro,relatime,uid=100000,gid=100000 - -/ # mount -o remount,rw /root/tmpfs /root/tmpfs -/ # findmnt | grep tmpfs -├─/root/tmpfs tmpfs tmpfs rw,relatime,uid=100000,gid=100000 -``` - -This feature, together with the user-namespace, ensures that even if a container -process has all Linux capabilities they can't be used to breach the container. - -Finally, Enhanced Container Isolation does system call vetting in such a way -that it does not affect the performance of containers in the great majority of -cases. It intercepts control-path system calls that are rarely used in most -container workloads but data-path system calls are not intercepted. - -### Filesystem user-ID mappings - -As mentioned above, Enhanced Container Isolation enables the Linux -user-namespace on all containers and this ensures that the container's user-ID -range (0->64K) maps to an unprivileged range of "real" user-IDs in the Docker -Desktop Linux VM (e.g., 100000->165535). - -Moreover, each container gets an exclusive range of real user-IDs in the Linux -VM (e.g., container 0 could get mapped to 100000->165535, container 2 to -165536->231071, container 3 to 231072->296607, and so on). Same applies to -group-IDs. In addition, if a container is stopped and restarted, there is no -guarantee it will receive the same mapping as before. This by design and further -improves security. - -However the above presents a problem when mounting Docker volumes into -containers, as the files written to such volumes will have the real -user/group-IDs and will therefore won't be accessible across a container's -start/stop/restart, or between containers due to the different real -user-ID/group-ID of each container. - -To solve this problem, Sysbox uses "filesystem user-ID remapping" via the Linux -Kernel's ID-mapped mounts feature (added in 2021) or an alternative module -called shiftfs. These technologies map filesystem accesses from the container's -real user-ID (e.g., range 100000->165535) to the range (0->65535) inside Docker -Desktop's Linux VM. This way, volumes can now be mounted or shared across -containers, even if each container uses an exclusive range of user-IDs. Users -need not worry about the container's real user-IDs. - -Note that although filesystem user-ID remapping may cause containers to access -Linux VM files mounted into the container with real user-ID 0 (i.e., root), the -[restricted mounts feature](#bind-mount-restrictions) described above ensures -that no Linux VM sensitive files can be mounted into the container. - -### Procfs & Sysfs Emulation - -Another feature of Enhanced Container Isolation is that inside each container, -the procfs ("/proc") and sysfs ("/sys") filesystems are partially emulated. This -serves several purposes, such as hiding sensitive host information inside the -container and namespacing host kernel resources that are not yet namespaced by -the Linux kernel itself. - -As a simple example, when Enhanced Container Isolation is enabled the -`/proc/uptime` file shows the uptime of the container itself, not that of the -Docker Desktop Linux VM: - -```console -$ docker run -it --rm alpine -/ # cat /proc/uptime -5.86 5.86 -``` - -In contrast, without Enhanced Container Isolation you see the uptime of -the Docker Desktop Linux VM. Though this is a trivial example, it shows how -Enhanced Container Isolation aims to prevent the Linux VM's configuration and -information from leaking into the container so as to make it more difficult to -breach the VM. - -In addition several other resources under `/proc/sys` that are not namespaced by -the Linux Kernel are also emulated inside the container. Each container -sees a separate view of each such resource and Sysbox reconciles the values -across the containers when programming the corresponding Linux kernel setting. - -This has the advantage of enabling container workloads that would otherwise -require truly privileged containers to access such non-namespaced kernel -resources to run with Enhanced Container Isolation enabled, thereby improving -security. diff --git a/content/desktop/hardened-desktop/enhanced-container-isolation/how-eci-works.md b/content/desktop/hardened-desktop/enhanced-container-isolation/how-eci-works.md deleted file mode 100644 index 5ffe0eaf4416..000000000000 --- a/content/desktop/hardened-desktop/enhanced-container-isolation/how-eci-works.md +++ /dev/null @@ -1,90 +0,0 @@ ---- -description: How Enhanced Container Isolation works -title: How does it work? -keywords: set up, enhanced container isolation, rootless, security ---- - -Docker implements Enhanced Container Isolation by using the [Sysbox -container runtime](https://github.com/nestybox/sysbox).

Use the following command to -disable the Docker Engine service, and to prevent it from starting automatically: - -```console -$ sudo systemctl disable docker docker.socket containerd -``` - -### Switching between Docker Desktop and Docker Engine - -The Docker CLI can be used to interact with multiple Docker Engines. For example, -you can use the same Docker CLI to control a local Docker Engine and to control -a remote Docker Engine instance running in the cloud. [Docker Contexts](../../engine/context/working-with-contexts.md) -allow you to switch between Docker Engines instances. - -When installing Docker Desktop, a dedicated "desktop-linux" context is created to -interact with Docker Desktop. On startup, Docker Desktop automatically sets its -own context (`desktop-linux`) as the current context. This means that subsequent -Docker CLI commands target Docker Desktop. On shutdown, Docker Desktop resets -the current context to the `default` context. - -Use the `docker context ls` command to view what contexts are available on your -machine.

Add the `SSH_AUTH_SOCK` environment variable in your container: - - ```console - $ -e SSH_AUTH_SOCK="/run/host-services/ssh-auth.sock" - ``` - -To enable the SSH agent in Docker Compose, add the following flags to your service: - - ```yaml -services: - web: - image: nginx:alpine - volumes: - - type: bind - source: /run/host-services/ssh-auth.sock - target: /run/host-services/ssh-auth.sock - environment: - - SSH_AUTH_SOCK=/run/host-services/ssh-auth.sock - ``` - -## Known limitations - -### Changing internal IP addresses - -The internal IP addresses used by Docker can be changed from **Settings**. After changing IPs, it is necessary to reset the Kubernetes cluster and to leave any active Swarm. - -### There is no docker0 bridge on the host - -Because of the way networking is implemented in Docker Desktop, you cannot -see a `docker0` interface on the host. This interface is actually within the -virtual machine. - -### I cannot ping my containers - -Docker Desktop can't route traffic to Linux containers. However if you're a Windows user, you can -ping the Windows containers. - -### Per-container IP addressing is not possible - -This is because the Docker `bridge` network is not reachable from the host. -However if you are a Windows user, per-container IP addressing is possible with Windows containers. - -## Use cases and workarounds - -### I want to connect from a container to a service on the host - -The host has a changing IP address, or none if you have no network access. -We recommend that you connect to the special DNS name `host.docker.internal`, -which resolves to the internal IP address used by the host. - -You can also reach the gateway using `gateway.docker.internal`. - -If you have installed Python on your machine, use the following instructions as an example to connect from a container to a service on the host: - -1. Run the following command to start a simple HTTP server on port 8000. - - `python -m http.server 8000` - - If you have installed Python 2.x, run `python -m SimpleHTTPServer 8000`. - -2. Now, run a container, install `curl`, and try to connect to the host using the following commands: - - ```console - $ docker run --rm -it alpine sh - # apk add curl - # curl http://host.docker.internal:8000 - # exit - ``` - -### I want to connect to a container from the host - -Port forwarding works for `localhost`. `--publish`, `-p`, or `-P` all work. -Ports exposed from Linux are forwarded to the host. - -We recommend you publish a port, or to connect from another -container. This is what you need to do even on Linux if the container is on an -overlay network, not a bridge network, as these are not routed. - -For example, to run an `nginx` webserver: - -```console -$ docker run -d -p 80:80 --name webserver nginx -``` - -To clarify the syntax, the following two commands both publish container's port `80` to host's port `8000`: - -```console -$ docker run --publish 8000:80 --name webserver nginx - -$ docker run -p 8000:80 --name webserver nginx -``` - -To publish all ports, use the `-P` flag. For example, the following command -starts a container (in detached mode) and the `-P` flag publishes all exposed ports of the -container to random ports on the host. - -```console -$ docker run -d -P --name webserver nginx -``` - -Alternatively, you can also use [host networking](../network/drivers/host.md#docker-desktop) -to give the container direct access to the network stack of the host. - -See the [run command](../reference/cli/docker/container/run.md) for more details on -publish options used with `docker run`. diff --git a/content/desktop/release-notes.md b/content/desktop/release-notes.md deleted file mode 100644 index c281a7c037de..000000000000 --- a/content/desktop/release-notes.md +++ /dev/null @@ -1,2597 +0,0 @@ ---- -description: Find the Docker Desktop release notes for Mac, Linux, and Windows. -keywords: Docker desktop, release notes, linux, mac, windows -title: Docker Desktop release notes -tags: [Release notes] -toc_max: 2 -aliases: -- /docker-for-mac/release-notes/ -- /docker-for-mac/edge-release-notes/ -- /desktop/mac/release-notes/ -- /docker-for-windows/edge-release-notes/ -- /docker-for-windows/release-notes/ -- /desktop/windows/release-notes/ -- /desktop/linux/release-notes/ -- /mackit/release-notes/ ---- - -This page contains information about the new features, improvements, known issues, and bug fixes in Docker Desktop releases.

To continue using Docker Desktop or to modify these settings, ensure you are signed in. -- To enable or disable **Manage Synchronized file shares with Compose**, **Access experimental features** and **Manage Synchronized file shares with Compose** have to be checked or unchecked at the same time. -- The Docker CLI will sometimes hang when running a container with the autoremove option (`--rm`) if the container fails to start (e.g.: `docker run --rm alpine invalidcommand`). In this case, the CLI process may need to be manually killed. - -#### For Windows - -- When starting Docker Desktop as a non-admin user, the following error connect `ENOENT \\.\pipe\errorReporter` might be triggered if the user is not a member of the **docker-users** group. -This can be resolved by adding the user to the **docker-users** group. Before starting Docker Desktop, make sure to sign out and then sign back in and unregister `docker-desktop` distribution if that was created, using `wsl --unregister docker-desktop`. - -#### For Linux - -- Ubuntu 24.04 LTS is not yet supported, Docker Desktop will fail to start. Due to a change in how the latest Ubuntu release restricts the unprivileged namespaces, `sudo sysctl -w kernel.apparmor_restrict_unprivileged_userns=0` needs to be ran at least once.

This means, Windows Home users will not be able to start Docker Desktop as WSL 2 is the only supported backend. To work around this issue, you must uninstall 4.5.0 from your machine and then download and install Docker Desktop 4.5.1 or a higher version. Alternatively, you can edit the Docker Desktop settings.json file located at `%APPDATA%\Docker\settings.json` and manually switch the value of the `wslEngineEnabled` field to `true`. - -## 4.4.4 - -{{< release-date date="2022-01-24" >}} - -### Bug fixes and enhancements - -#### For Windows - -- Fixed logging in from WSL 2.

By default, Docker Desktop is set to use up to `2` GB of your host's - memory. To increase the RAM, set this to a higher number; to decrease it, - lower the number. - -- **Swap**. Configure swap file size as needed. The default is 1 GB. - -- **Virtual disk limit**. Specify the maximum size of the disk image. - -- **Disk image location**. Specify the location of the Linux volume where containers and images are stored. - - You can also move the disk image to a different location. If you attempt to - move a disk image to a location that already has one, you are asked if you - want to use the existing image or replace it. - ->**Tip** -> -> If you feel Docker Desktop starting to get slow or you're running -> multi-container workloads, increase the memory and disk image space allocation -{ .tip } - -- **Resource Saver**. Enable or disable [Resource Saver mode](../use-desktop/resource-saver.md), - which significantly reduces CPU and memory utilization on the host by - automatically turning off the Linux VM when Docker Desktop is idle (i.e., no - containers are running). - - You can also configure the Resource Saver timeout which indicates how long - should Docker Desktop be idle before Resource Saver mode kicks in. Default is - 5 minutes. - - >**Note** - > - > Exit from Resource Saver mode occurs automatically when containers run. Exit - > may take a few seconds (~3 to 10 secs) as Docker Desktop restarts the Linux VM. - -### File sharing - -> **Note** -> -> The **File sharing** tab is only available in Hyper-V mode because the files -> are automatically shared in WSL 2 mode and Windows container mode. - -Use File sharing to allow local directories on your machine to be shared with -Linux containers. This is especially useful for editing source code in an IDE on -the host while running and testing the code in a container. - -Note that configuring file sharing is not necessary for Windows containers, -only [Linux containers](../faqs/windowsfaqs.md#how-do-i-switch-between-windows-and-linux-containers). -If a directory is not shared with a Linux container you may get `file not found` -or `cannot start service` errors at runtime. See [Volume mounting requires shared folders for Linux containers](../troubleshoot/topics.md). - -File share settings are: - -- **Add a Directory**. select `+` and navigate to the directory you want to add. - -- **Remove a Directory**. select `-` next to the directory you want to remove - -- **Apply & Restart** makes the directory available to containers using Docker's - bind mount (`-v`) feature. - -> Tips on shared folders, permissions, and volume mounts -> -> * Share only the directories that you need with the container. File sharing -> introduces overhead as any changes to the files on the host need to be notified -> to the Linux VM. Sharing too many files can lead to high CPU load and slow -> filesystem performance. -> * Shared folders are designed to allow application code to be edited -> on the host while being executed in containers. For non-code items -> such as cache directories or databases, the performance will be much -> better if they are stored in the Linux VM, using a [data volume](../../storage/volumes.md) -> (named volume) or [data container](../../storage/volumes.md). -> * Docker Desktop sets permissions to read/write/execute for users, groups and -> others [0777 or a+rwx](https://chmodcommand.com/chmod-0777/). -> This is not configurable. See [Permissions errors on data directories for shared volumes](../troubleshoot/topics.md). -> * Windows presents a case-insensitive view of the filesystem to applications while Linux is case-sensitive. -> On Linux, it is possible to create two separate files: `test` and `Test`, -> while on Windows these filenames would actually refer to the same underlying -> file. This can lead to problems where an app works correctly on a developer's -> machine (where the file contents are shared) but fails when run in Linux in -> production (where the file contents are distinct). To avoid this, Docker Desktop -> insists that all shared files are accessed as their original case. Therefore, -> if a file is created called `test`, it must be opened as `test`. Attempts to -> open `Test` will fail with the error "No such file or directory". Similarly, -> once a file called `test` is created, attempts to create a second file called -> `Test` will fail. -{ .tip } - -#### Shared folders on demand - -You can share a folder "on demand" the first time a particular folder is used by a container. - -If you run a Docker command from a shell with a volume mount (as shown in the -example below) or kick off a Compose file that includes volume mounts, you get a -popup asking if you want to share the specified folder. - -You can select to **Share it**, in which case it is added to your Docker Desktop Shared Folders list and available to -containers. Alternatively, you can opt not to share it by selecting **Cancel**. - -![Shared folder on demand](../images/shared-folder-on-demand.png) - -### Proxies - -Docker Desktop on Windows supports the use of HTTP/HTTPS and [SOCKS5 proxies](../networking.md#socks5-proxy-support). - -HTTP/HTTPS proxies can be used when: - -- Signing in to Docker -- Pulling or pushing images -- Fetching artifacts during image builds -- Containers interact with the external network -- Scanning images - -If the host uses a HTTP/HTTPS proxy configuration (static or via Proxy Auto-Configuration (PAC)), Docker Desktop reads -this configuration -and automatically uses these settings for signing into Docker, for pulling and pushing images, and for -container Internet access. - -To set a different proxy for Docker Desktop, turn on **Manual proxy configuration** and enter a single -upstream proxy URL of the form `http://proxy:port` or `https://proxy:port`. - -To prevent developers from accidentally changing the proxy settings, see -[Settings Management](../hardened-desktop/settings-management/index.md#what-features-can-i-configure-with-settings-management). - -The HTTPS proxy settings used for scanning images are set using the `HTTPS_PROXY` environment variable. - -If you are running Windows containers in Docker, you can allow the Windows Docker daemon to use Docker Desktop's internal proxy, with the **Use proxy for Windows Docker daemon** setting. -This is useful when a corporate proxy that requires authentication is manually configured or set at the system level. If you are an admin for your organization and have a Docker Business subscription, you can control this setting with [Settings management](../hardened-desktop/settings-management/configure.md) using the `windowsDockerdPort` parameter. - -> **Note** -> -> If you are using a PAC file hosted on a web server, make sure to add the MIME type `application/x-ns-proxy-autoconfig` for the `.pac` file extension on the server or website. Without this configuration, the PAC file may not be parsed correctly. - -#### Proxy authentication - -Docker Desktop supports Basic, Kerberos and NTLM proxy authentication methods. - -##### Basic authentication - -If your proxy uses Basic authentication, Docker Desktop prompts developers for a username and password and caches the credentials. All passwords are stored securely in the OS credential store. It will request re-authentication if that cache is removed. - -It's recommended that you use an `https://` URL for HTTP/HTTPS proxies to protect passwords during network transit. Docker Desktop also supports TLS 1.3 for communication with proxies. - -##### Kerberos and NTLM authentication - -Kerberos and NTLM proxy authentication are available for Business subscribers with Docker Desktop version 4.30 and later. No additional configuration is needed beyond specifying the proxy IP address and port. - -Developers are no longer interrupted by prompts for proxy credentials as authentication is centralized. This also reduces the risk of account lockouts due to incorrect sign in attempts. - -If your proxy offers multiple authentication schemes in 407(Proxy Authentication Required) response, Docker Desktop by default selects Basic authentication scheme. If your proxy server is properly configured for Kerberos or NTLM authentication, you can enable Kerberos/NTLM proxy authentication during Docker Desktop installation. To do that, you will have install Docker Deskop from command line and pass the installer flag '--proxy-enable-kerberosntlm'. - - -> **Note** -> -> Docker Desktop also supports the use of [SOCKS5 proxies](../networking.md#socks5-proxy-support). - - -### Network - -> **Note** -> -> The **Network** tab isn't available in the Windows container mode because -> Windows manages networking. - -{{< include "desktop-network-setting.md" >}} - -### WSL Integration - -In WSL 2 mode, you can configure which WSL 2 distributions will have the Docker -WSL integration. - -By default, the integration is enabled on your default WSL distribution. -To change your default WSL distro, run `wsl --set-default `. (For example, -to set Ubuntu as your default WSL distro, run `wsl --set-default ubuntu`). - -You can also select any additional distributions you would like to enable the WSL 2 integration on. - -For more details on configuring Docker Desktop to use WSL 2, see -[Docker Desktop WSL 2 backend](../wsl/index.md). - -## Docker Engine - -The **Docker Engine** tab allows you to configure the Docker daemon used to run containers with Docker Desktop. - -You configure the daemon using a JSON configuration file. Here's what the file might look like: - -```json -{ - "builder": { - "gc": { - "defaultKeepStorage": "20GB", - "enabled": true - } - }, - "experimental": false -} -``` - -You can find this file at `$HOME/.docker/daemon.json`. To change the configuration, either -edit the JSON configuration directly from the dashboard in Docker Desktop, or open and -edit the file using your favorite text editor. - -To see the full list of possible configuration options, see the -[dockerd command reference](/reference/cli/dockerd/). - -Select **Apply & Restart** to save your settings and restart Docker Desktop. - -## Builders - -{{< include "desktop-builders-setting.md" >}} - -## Kubernetes - -> **Note** -> -> The **Kubernetes** tab is not available in Windows container mode. - -Docker Desktop includes a standalone Kubernetes server, so that you can test -deploying your Docker workloads on Kubernetes.

Applications that behave in this way - include: - - - `rake` - - `ember build` - - Symfony - - Magento - - Zend Framework - - PHP applications that use [Composer](https://getcomposer.org) to install - dependencies in a `vendor` folder - - As a workaround for this behavior, you can put vendor or third-party library - directories in Docker volumes, perform temporary file system operations - outside of bind mounts, and use third-party tools like Unison or `rsync` to - synchronize between container directories and bind-mounted directories.

The bug is fixed in newer versions of `libssl` in `debian:bullseye`, `ubuntu:21.04`, and `fedora:35`. -- Some command line tools do not work when Rosetta 2 is not installed. - - The old version 1.x of `docker-compose`.

You can add `--platform linux/amd64` to run (or build) an Intel image using emulation. - - However, attempts to run Intel-based containers on Apple silicon machines under emulation can crash as qemu sometimes fails to run the container. In addition, filesystem change notification APIs (`inotify`) do not work under qemu emulation. Even when the containers do run correctly under emulation, they will be slower and use more memory than the native equivalent. - - In summary, running Intel-based containers on Arm-based machines should be regarded as "best effort" only. We recommend running arm64 containers on Apple silicon machines whenever possible, and encouraging container authors to produce arm64, or multi-arch, versions of their containers.

From **Settings**, select **Resources** and then **File sharing**. Share the drive that contains the Dockerfile and volume. - -### Docker Desktop fails to start on MacOS or Linux platforms - -On MacOS and Linux, Docker Desktop creates Unix domain sockets used for inter-process communication. - -Docker fails to start if the absolute path length of any of these sockets exceeds the OS limitation which is 104 characters on MacOS and 108 characters on Linux. These sockets are created under the user's home directory. If the user ID length is such that the absolute path of the socket exceeds the OS path length limitation, then Docker Desktop is unable to create the socket and fails to start. The workaround for this is to shorten the user ID which we recommend has a maximum length of 33 characters on MacOS and 55 characters on Linux. - -Following are the examples of errors on MacOS which indicate that the startup failure was due to exceeding the above mentioned OS limitation: - -```console -[vpnkit-bridge][F] listen unix /Library/Containers/com.docker.docker/Data/http-proxy-control.sock: bind: invalid argument -``` - -```console -[com.docker.backend][E] listen(vsock:4099) failed: listen unix /Library/Containers/com.docker.docker/Data/vms/0/00000002.00001003: bind: invalid argument -``` - -## Topics for Mac - -### Incompatible CPU detected - -Docker Desktop requires a processor (CPU) that supports virtualization and, more -specifically, the [Apple Hypervisor -framework](https://developer.apple.com/library/mac/documentation/DriversKernelHardware/Reference/Hypervisor/). -Docker Desktop is only compatible with Mac systems that have a CPU that supports the Hypervisor framework. Most Macs built in 2010 and later support it,as described in the Apple Hypervisor Framework documentation about supported hardware: - -*Generally, machines with an Intel VT-x feature set that includes Extended Page -Tables (EPT) and Unrestricted Mode are supported.* - -To check if your Mac supports the Hypervisor framework, run the following command in a terminal window. - -```console -$ sysctl kern.hv_support -``` - -If your Mac supports the Hypervisor Framework, the command prints -`kern.hv_support: 1`. - -If not, the command prints `kern.hv_support: 0`. - -See also, [Hypervisor Framework -Reference](https://developer.apple.com/library/mac/documentation/DriversKernelHardware/Reference/Hypervisor/) -in the Apple documentation, and Docker Desktop [Mac system requirements](../install/mac-install.md#system-requirements). - -### VPNKit keeps breaking - -In Docker Desktop version 4.19, gVisor replaced VPNKit to enhance the performance of VM networking when using the Virtualization framework on macOS Ventura and above. - -To continue using VPNKit, add `"networkType":"vpnkit"` to your `settings.json` file located at `~/Library/Group Containers/group.com.docker/settings.json`. - -## Topics for Windows - -### Volumes - -#### Permissions errors on data directories for shared volumes - -When sharing files from Windows, Docker Desktop sets permissions on [shared volumes](../settings/windows.md#file-sharing) -to a default value of [0777](https://chmodcommand.com/chmod-0777/) -(`read`, `write`, `execute` permissions for `user` and for `group`). - -The default permissions on shared volumes are not configurable. If you are -working with applications that require permissions different from the shared -volume defaults at container runtime, you need to either use non-host-mounted -volumes or find a way to make the applications work with the default file -permissions. - -See also, -[Can I change permissions on shared volumes for container-specific deployment requirements?](../faqs/windowsfaqs.md#can-i-change-permissions-on-shared-volumes-for-container-specific-deployment-requirements) -in the FAQs. - -#### Volume mounting requires shared folders for Linux containers - -If you are using mounted volumes and get runtime errors indicating an -application file is not found, access is denied to a volume mount, or a service -cannot start, such as when using [Docker Compose](../../compose/gettingstarted.md), -you might need to turn on [shared folders](../settings/windows.md#file-sharing). - -With the Hyper-V backend, mounting files from Windows requires shared folders for Linux containers. From **Settings**, select **Shared Folders** and share the folder that contains the -Dockerfile and volume. - -#### Support for symlinks - -Symlinks work within and across containers. To learn more, see [How do symlinks work on Windows?](../faqs/windowsfaqs.md#how-do-symlinks-work-on-windows). - -#### Avoid unexpected syntax errors, use Unix style line endings for files in containers - -Any file destined to run inside a container must use Unix style `\n` line -endings. This includes files referenced at the command line for builds and in -RUN commands in Docker files. - -Docker containers and `docker build` run in a Unix environment, so files in -containers must use Unix style line endings: `\n`, _not_ Windows style: `\r\n`. -Keep this in mind when authoring files such as shell scripts using Windows -tools, where the default is likely to be Windows style line endings. These -commands ultimately get passed to Unix commands inside a Unix based container -(for example, a shell script passed to `/bin/sh`). If Windows style line endings -are used, `docker run` fails with syntax errors. - -For an example of this issue and the resolution, see this issue on GitHub: -[Docker RUN fails to execute shell -script](https://github.com/moby/moby/issues/24388). - -#### Path conversion on Windows - -On Linux, the system takes care of mounting a path to another path. For example, when you run the following command on Linux: - -```console -$ docker run --rm -ti -v /home/user/work:/work alpine -``` - -It adds a `/work` directory to the target container to mirror the specified path. - -However, on Windows, you must update the source path. For example, if you are using -the legacy Windows shell (`cmd.exe`), you can use the following command: - -```console -$ docker run --rm -ti -v C:\Users\user\work:/work alpine -``` - -This starts the container and ensures the volume becomes usable. This is possible because Docker Desktop detects -the Windows-style path and provides the appropriate conversion to mount the directory. - -Docker Desktop also allows you to use Unix-style path to the appropriate format. For example: - -```console -$ docker run --rm -ti -v /c/Users/user/work:/work alpine ls /work -``` - -#### Working with Git Bash - -Git Bash (or MSYS) provides a Unix-like environment on Windows. These tools apply their own -preprocessing on the command line. For example, if you run the following command in Git Bash, it gives an error: - -```console -$ docker run --rm -ti -v C:\Users\user\work:/work alpine -docker: Error response from daemon: mkdir C:UsersUserwork: Access is denied. -``` - -This is because the `\` character has a special meaning in Git Bash. If you are using Git Bash, you must neutralize it using `\\`: - -```console -$ docker run --rm -ti -v C:\\Users\\user\\work:/work alpine -``` - -Also, in scripts, the `pwd` command is used to avoid hard-coding file system locations. Its output is a Unix-style path. - -```console -$ pwd -/c/Users/user/work -``` - -Combined with the `$()` syntax, the command below works on Linux, however, it fails on Git Bash. - -```console -$ docker run --rm -ti -v $(pwd):/work alpine -docker: Error response from daemon: OCI runtime create failed: invalid mount {Destination:\Program Files\Git\work Type:bind Source:/run/desktop/mnt/host/c/Users/user/work;C Options:[rbind rprivate]}: mount destination \Program Files\Git\work not absolute: unknown. -``` - -You can work around this issue by using an extra `/` - -```console -$ docker run --rm -ti -v /$(pwd):/work alpine -``` - -Portability of the scripts is not affected as Linux treats multiple `/` as a single entry. -Each occurrence of paths on a single line must be neutralized. - -```console -$ docker run --rm -ti -v /$(pwd):/work alpine ls /work -ls: C:/Program Files/Git/work: No such file or directory -``` - -In this example, The `$(pwd)` is not converted because of the preceding '/'. However, the second '/work' is transformed by the -POSIX layer before passing it to Docker Desktop. You can also work around this issue by using an extra `/`. - -```console -$ docker run --rm -ti -v /$(pwd):/work alpine ls //work -``` - -To verify whether the errors are generated from your script, or from another source, you can use an environment variable. For example: - -```console -$ MSYS_NO_PATHCONV=1 docker run --rm -ti -v $(pwd):/work alpine ls /work -``` - -It only expects the environment variable here. The value doesn't matter. - -In some cases, MSYS also transforms colons to semicolon. Similar conversions can also occur -when using `~` because the POSIX layer translates it to a DOS path. `MSYS_NO_PATHCONV` also works in this case. - -### Virtualization - -Your machine must have the following features for Docker Desktop to function correctly: - -#### WSL 2 and Windows Home - -1. Virtual Machine Platform -2. [Windows Subsystem for Linux](https://docs.microsoft.com/en-us/windows/wsl/install-win10) -3.

Hypervisor enabled at Windows startup - -![Hyper-V on Windows features](../images/hyperv-enabled.png) - -Docker Desktop requires Hyper-V as well as the Hyper-V Module for Windows -PowerShell to be installed and enabled. The Docker Desktop installer enables -it for you. - -Docker Desktop also needs two CPU hardware features to use Hyper-V: Virtualization and Second Level Address Translation (SLAT), which is also called Rapid Virtualization Indexing (RVI). On some systems, Virtualization must be enabled in the BIOS. The steps required are vendor-specific, but typically the BIOS option is called `Virtualization Technology (VTx)` or something similar. Run the command `systeminfo` to check all required Hyper-V features. See [Pre-requisites for Hyper-V on Windows 10](https://docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/reference/hyper-v-requirements) for more details. - -To install Hyper-V manually, see [Install Hyper-V on Windows 10](https://msdn.microsoft.com/en-us/virtualization/hyperv_on_windows/quick_start/walkthrough_install). A reboot is *required* after installation. If you install Hyper-V without rebooting, Docker Desktop does not work correctly. - -From the start menu, type **Turn Windows features on or off** and press enter. -In the subsequent screen, verify that Hyper-V is enabled. - -#### Virtualization must be turned on - -In addition to [Hyper-V](#hyper-v) or [WSL 2](../wsl/index.md), virtualization must be turned on. Check the -Performance tab on the Task Manager. Alternatively, you can type 'systeminfo' into your terminal. If you see 'Hyper-V Requirements: A hypervisor has been detected. Features required for Hyper-V will not be displayed', then virtualization is enabled. - -![Task Manager](../images/virtualization-enabled.png) - -If you manually uninstall Hyper-V, WSL 2 or turn off virtualization, -Docker Desktop cannot start. - -To turn on nested virtualisation, see [Run Docker Desktop for Windows in a VM or VDI environment](../vm-vdi.md#turn-on-nested-virtualization). - -#### Hypervisor enabled at Windows startup - -If you have completed the steps described above and are still experiencing -Docker Desktop startup issues, this could be because the Hypervisor is installed, -but not launched during Windows startup. Some tools (such as older versions of -Virtual Box) and video game installers turn off hypervisor on boot. To turn it back on: - -1. Open an administrative console prompt. -2. Run `bcdedit /set hypervisorlaunchtype auto`. -3. Restart Windows. - -You can also refer to the [Microsoft TechNet article](https://social.technet.microsoft.com/Forums/en-US/ee5b1d6b-09e2-49f3-a52c-820aafc316f9/hyperv-doesnt-work-after-upgrade-to-windows-10-1809?forum=win10itprovirt) on Code flow guard (CFG) settings. - -#### Turn on nested virtualization - -If you are using Hyper-V and you get the following error message when running Docker Desktop in a VDI environment: - -```console -The Virtual Machine Management Service failed to start the virtual machine 'DockerDesktopVM' because one of the Hyper-V components is not running -``` - -Try [enabling nested virtualization](../vm-vdi.md#turn-on-nested-virtualization). - - -### Windows containers and Windows Server - -Docker Desktop is not supported on Windows Server.

On installation you receive a UAC prompt which allows a privileged helper service to be installed. After that, Docker Desktop can be run without administrator privileges, provided you are members of the `docker-users` group. If you performed the installation, you are automatically added to this group, but other users must be added manually. This allows the administrator to control who has access to Docker Desktop. - -The reason for this approach is that Docker Desktop needs to perform a limited set of privileged operations which are conducted by the privileged helper process `com.docker.service`. This approach allows, following the principle of least privilege, `Administrator` access to be used only for the operations for which it is absolutely necessary, while still being able to use Docker Desktop as an unprivileged user. - -## Privileged helper - -The privileged helper `com.docker.service` is a Windows service which runs in the background with `SYSTEM` privileges. It listens on the named pipe `//./pipe/dockerBackendV2`. The developer runs the Docker Desktop application, which connects to the named pipe and sends commands to the service. This named pipe is protected, and only users that are part of the `docker-users` group can have access to it. - -The service performs the following functionalities: -- Ensuring that `kubernetes.docker.internal` is defined in the Win32 hosts file. Defining the DNS name `kubernetes.docker.internal` allows Docker to share Kubernetes contexts with containers. -- Ensuring that `host.docker.internal` and `gateway.docker.internal` are defined in the Win32 hosts file. They point to the host local IP address and allow an application to resolve the host IP using the same name from either the host itself or a container. -- Securely caching the Registry Access Management policy which is read-only for the developer. -- Creating the Hyper-V VM `"DockerDesktopVM"` and managing its lifecycle - starting, stopping and destroying it. The VM name is hard coded in the service code so the service cannot be used for creating or manipulating any other VMs. -- Moving the VHDX file or folder. -- Starting and stopping the Windows Docker engine and querying whether it's running. -- Deleting all Windows containers data files. -- Checking if Hyper-V is enabled. -- Checking if the bootloader activates Hyper-V. -- Checking if required Windows features are both installed and enabled. -- Conducting healthchecks and retrieving the version of the service itself. - -The service start mode depends on which container engine is selected, and, for WSL, on whether it is needed to maintain `host.docker.internal` and `gateway.docker.internal` in the Win32 hosts file. This is controlled by a setting under `Use the WSL 2 based engine` in the settings page. When this is set, WSL engine behaves the same as Hyper-V. So: -- With Windows containers, or Hyper-v Linux containers, the service is started when the system boots and runs all the time, even when Docker Desktop isn't running. This is required so you can launch Docker Desktop without admin privileges. -- With WSL2 Linux containers, the service isn't necessary and therefore doesn't run automatically when the system boots. When you switch to Windows containers or Hyper-V Linux containers, or choose to maintain `host.docker.internal` and `gateway.docker.internal` in the Win32 hosts file, a UAC prompt is displayed which asks you to accept the privileged operation to start the service. If accepted, the service is started and set to start automatically upon the next Windows boot. - -## Containers running as root within the Linux VM - -The Linux Docker daemon and containers run in a minimal, special-purpose Linux -VM managed by Docker. It is immutable so you can’t extend it or change the -installed software. This means that although containers run by default as -`root`, this doesn't allow altering the VM and doesn't grant `Administrator` -access to the Windows host machine. The Linux VM serves as a security boundary -and limits what resources from the host can be accessed. File sharing uses a -user-space crafted file server and any directories from the host bind mounted -into Docker containers still retain their original permissions. It doesn't give -you access to any files that it doesn’t already have access to. - -## Enhanced Container Isolation - -In addition, Docker Desktop supports [Enhanced Container Isolation -mode](../hardened-desktop/enhanced-container-isolation/_index.md) (ECI), -available to Business customers only, which further secures containers without -impacting developer workflows. - -ECI automatically runs all containers within a Linux user-namespace, such that -root in the container is mapped to an unprivileged user inside the Docker -Desktop VM. ECI uses this and other advanced techniques to further secure -containers within the Docker Desktop Linux VM, such that they are further -isolated from the Docker daemon and other services running inside the VM. - -## Windows Containers - -Unlike the Linux Docker engine and containers which run in a VM, Windows containers are an operating system feature, and run directly on the Windows host with `Administrator` privileges. For organizations who don't want their developers to run Windows containers, a `–no-windows-containers` installer flag is available from version 4.11 to disable their use. - -## Networking - -For network connectivity, Docker Desktop uses a user-space process (`vpnkit`), which inherits constraints like firewall rules, VPN, HTTP proxy properties etc. from the user that launched it. diff --git a/content/desktop/wsl/_index.md b/content/desktop/wsl/_index.md deleted file mode 100644 index 8e44e0f7173f..000000000000 --- a/content/desktop/wsl/_index.md +++ /dev/null @@ -1,105 +0,0 @@ ---- -description: Turn on the Docker WSL 2 backend and get to work using best practices, - GPU support, and more in this thorough guide. -keywords: wsl, wsl2, installing wsl2, wsl installation, docker wsl2, wsl docker, wsl2 - tech preview, wsl install docker, install docker wsl, how to install docker in wsl -title: Docker Desktop WSL 2 backend on Windows -aliases: -- /docker-for-windows/wsl/ -- /docker-for-windows/wsl-tech-preview/ -- /desktop/windows/wsl/ ---- - -Windows Subsystem for Linux (WSL) 2 is a full Linux kernel built by Microsoft, which lets Linux distributions run without managing virtual machines.

This - default rule sets builds from the `Branch` in your source code repository called - `master` or `main`, and creates a Docker image tagged with `latest`. For more information, see [set up build rules](#set-up-build-rules) - -7. Optional: Select the **plus** icon to add and [configure more build rules](#set-up-build-rules). - -8.

This - tells the build system what to look for in the source code repository. - -* Enter the name of the **Source** branch or tag you want to build. - - The first time you configure Automated builds, a default build rule is set up - for you. This default set builds from the `Branch` in your source code called - `master`, and creates a Docker image tagged with `latest`. - - You can also use a regex to select which source branches or tags to build. - To learn more, see - [regexes](#regexes-and-automated-builds). - -* Enter the tag to apply to Docker images built from this source. - - If you configured a regex to select the source, you can reference the - capture groups and use its result as part of the tag. To learn more, see - [regexes](#regexes-and-automated-builds). - -* Specify the **Dockerfile location** as a path relative to the root of the source code repository. If the Dockerfile is at the repository root, leave this path set to `/`. - -> **Note** -> -> When Docker Hub pulls a branch from a source code repository, it performs a -> shallow clone - only the tip of the specified branch. Refer to -> [Advanced options for Autobuild and Autotest](advanced.md#source-repository-or-branch-clones) -> for more information. - -### Environment variables for builds - -You can set the values for environment variables used in your build processes -when you configure an automated build. Add your build environment variables by -selecting the **plus** icon next to the **Build environment variables** section, and -then entering a variable name and the value. - -When you set variable values from the Docker Hub UI, you can use them by the -commands you set in `hooks` files. However, they're stored so that only users who have `admin` access to the Docker Hub repository can see their values. This -means you can use them to store access tokens or other information that -should remain secret. - -> **Note** -> -> The variables set on the build configuration screen are used during -> the build processes only and shouldn't get confused with the environment -> values used by your service, for example to create service links. - -## Advanced automated build options - -At the minimum you need a build rule composed of a source branch, or tag, and a -destination Docker tag to set up an automated build. You can also: - -- Change where the build looks for the Dockerfile -- Set a path to the files the build should use (the build context) -- Set up multiple static tags or branches to build from -- Use regular expressions (regexes) to dynamically select source code to build and -create dynamic tags - -All of these options are available from the **Build configuration** screen for -each repository. Select **Repositories** from the left navigation, and select the name of the repository you want to edit. Select the **Builds** tab, and then select **Configure Automated builds**. - -### Tag and branch builds - -You can configure your automated builds so that pushes to specific branches or tags triggers a build. - -1.

To learn more, see - > [regexes](index.md#regexes-and-automated-builds). - -5. Repeat steps 2 through 4 for each new build rule you set up. - -### Set the build context and Dockerfile location - -Depending on how you arrange the files in your source code repository, the -files required to build your images may not be at the repository root. If that's -the case, you can specify a path where the build looks for the files. - -The build context is the path to the files needed for the build, relative to -the root of the repository. Enter the path to these files in the **Build context** field. Enter `/` to set the build context as the root of the source code repository. - -> **Note** -> -> If you delete the default path `/` from the **Build context** field and leave -> it blank, the build system uses the path to the Dockerfile as the build -> context. However, to avoid confusion it's recommended that you specify the -> complete path. - -You can specify the **Dockerfile location** as a path relative to the build -context. If the Dockerfile is at the root of the build context path, leave the -Dockerfile path set to `/`. If the build context field is blank, set the path -to the Dockerfile from the root of the source repository. - -### Regexes and Automated builds - -You can specify a regular expression (regex) so that only matching branches or -tags are built. You can also use the results of the regex to create the Docker -tag that's applied to the built image. - -You can use up to nine regular expression capture groups, or expressions enclosed in parentheses, to select a source to build, and reference -these in the **Docker Tag** field using `{\1}` through `{\9}`. - - - -### Build images with BuildKit - -Autobuilds use the BuildKit build system by default. If you want to use the legacy -Docker build system, add the [environment variable](index.md#environment-variables-for-builds) -`DOCKER_BUILDKIT=0`. Refer to the [BuildKit](../../build/buildkit/index.md) -page for more information on BuildKit. - -## Autobuild for teams - -When you create an automated build repository in your own user account, you -can start, cancel, and retry builds, and edit and delete your own repositories. - -These same actions are also available for team repositories from Docker Hub if -you are an owner. If you are a member of a -team with `write` permissions you can start, cancel, and retry builds in your -team's repositories, but you cannot edit the team repository settings or delete -the team repositories. If your user account has `read` permission, or if you're -a member of a team with `read` permission, you can view the build configuration -including any testing settings. - -| Action/Permission | Read | Write | Admin | Owner | -| --------------------- | ---- | ----- | ----- | ----- | -| view build details | x | x | x | x | -| start, cancel, retry | | x | x | x | -| edit build settings | | | x | x | -| delete build | | | | x | - -### Service users for team autobuilds - -> **Note** -> -> Only owners can set up Automated builds for teams. - -When you set up Automated builds for teams, you grant Docker Hub access to -your source code repositories using OAuth tied to a specific user account. This -means that Docker Hub has access to everything that the linked source provider -account can access. - -For organizations and teams, it's recommended you create a dedicated service account to grant access to the source provider. This ensures that no -builds break as individual users' access permissions change, and that an -individual user's personal projects aren't exposed to an entire organization. - -This service account should have access to any repositories to be built, -and must have administrative access to the source code repositories so it can -manage deploy keys. If needed, you can limit this account to only a specific -set of repositories required for a specific build. - -If you are building repositories with linked private submodules (private -dependencies), you also need to add an override `SSH_PRIVATE` environment -variable to automated builds associated with the account. For more information, see [Troubleshoot](troubleshoot.md#build-repositories-with-linked-private-submodules) - -1. Create a service user account on your source provider, and generate SSH keys for it. -2. Create a "build" team in your organization. -3. Ensure that the new "build" team has access to each repository and submodule you need to build. - - Go to the repository's **Settings** page. On GitHub, add the new "build" team - to the list of **Collaborators and Teams**. On Bitbucket, add the "build" team - to the list of approved users on the **Access management** screen. - -4. Add the service user to the "build" team on the source provider. - -5. Sign in to Docker Hub as an owner, switch to the organization, and follow the instructions to [link to source code repository](link-source.md) using the service account. - - > **Note** - > - > You may need to log out of your individual account on the source code provider to create the link to the service account. - -6.

Run `docker run hello-world` to run the image locally. You should see output similar to: - - ```console - $ docker run hello-world - Hello from Docker! - This message shows that your installation appears to be working correctly. - - To generate this message, Docker took the following steps: - 1. The Docker client contacted the Docker daemon. - 2. The Docker daemon pulled the "hello-world" image from the Docker Hub. - (amd64) - 3. The Docker daemon created a new container from that image which runs the - executable that produces the output you are currently reading. - 4.

Start by creating a [Dockerfile](../reference/dockerfile.md) to specify your application as shown below: - - ```dockerfile - # syntax=docker/dockerfile:1 - FROM busybox - CMD echo "Hello world! This is my first Docker image." - ``` - -2. Run `docker build -t /my-private-repo .` to build your Docker - image. - -3. Run `docker run /my-private-repo` to test your -Docker image locally. - -4. Run `docker push /my-private-repo` to push your Docker image to Docker Hub.

The Docker platform runs natively on Linux (on x86-64, ARM and many other CPU architectures) and on Windows (x86-64). - -Docker Inc. builds products that let you build and run containers on Linux, Windows and macOS. - -### What does Docker technology add to just plain LXC? - -Docker technology is not a replacement for [LXC](https://linuxcontainers.org/). "LXC" refers to capabilities of -the Linux kernel (specifically namespaces and control groups) which allow -sandboxing processes from one another, and controlling their resource -allocations. On top of this low-level foundation of kernel features, Docker -offers a high-level tool with several powerful functionalities: - - - *Portable deployment across machines.* Docker defines a format for bundling - an application and all its dependencies into a single object called a container. This container can be - transferred to any Docker-enabled machine. The container can be executed there with the - guarantee that the execution environment exposed to the application is the - same in development, testing, and production. LXC implements process sandboxing, which is an important pre-requisite - for portable deployment, but is not sufficient for portable deployment. - If you sent me a copy of your application installed in a custom LXC - configuration, it would almost certainly not run on my machine the way it does - on yours. The app you sent me is tied to your machine's specific configuration: - networking, storage, logging, etc. Docker defines an abstraction for - these machine-specific settings. The exact same Docker container can - run - unchanged - on many different machines, with many different - configurations. - - - *Application-centric.* Docker is optimized for the deployment of - applications, as opposed to machines. This is reflected in its API, user - interface, design philosophy and documentation. By contrast, the `lxc` helper - scripts focus on containers as lightweight machines - basically servers that - boot faster and need less RAM. We think there's more to containers than just - that. - - - *Automatic build.* Docker includes [*a tool for developers to automatically - assemble a container from their source - code*](/reference/dockerfile/), with full control over application - dependencies, build tools, packaging etc. They are free to use `make`, `maven`, - `chef`, `puppet`, `salt,` Debian packages, RPMs, source tarballs, or any - combination of the above, regardless of the configuration of the machines. - - - *Versioning.* Docker includes git-like capabilities for tracking successive - versions of a container, inspecting the diff between versions, committing new - versions, rolling back etc. The history also includes how a container was - assembled and by whom, so you get full traceability from the production server - all the way back to the upstream developer. Docker also implements incremental - uploads and downloads, similar to `git pull`, so new versions of a container - can be transferred by only sending diffs. - - - *Component re-use.* Any container can be used as a [base image](../glossary.md#base-image) to -create more specialized components. This can be done manually or as part of an -automated build. For example you can prepare the ideal Python environment, and -use it as a base for 10 different applications. Your ideal PostgreSQL setup can -be re-used for all your future projects. And so on. - - - *Sharing.* Docker has access to a public registry [on Docker -Hub](https://hub.docker.com/) where thousands of -people have uploaded useful images: anything from Redis, CouchDB, PostgreSQL to -IRC bouncers to Rails app servers to Hadoop to base images for various Linux -distros. The registry also includes an official "standard -library" of useful containers maintained by the Docker team. The registry itself -is open-source, so anyone can deploy their own registry to store and transfer -private containers, for internal server deployments for example. - - - *Tool ecosystem.* Docker defines an API for automating and customizing the - creation and deployment of containers. There are a huge number of tools - integrating with Docker to extend its capabilities. PaaS-like deployment - (Dokku, Deis, Flynn), multi-node orchestration (Maestro, Salt, Mesos, Openstack - Nova), management dashboards (docker-ui, Openstack Horizon, Shipyard), - configuration management (Chef, Puppet), continuous integration (Jenkins, - Strider, Travis), etc. Docker is rapidly establishing itself as the standard - for container-based tooling. - -### What is different between a Docker container and a VM? - -There's a great StackOverflow answer [showing the differences]( -https://stackoverflow.com/questions/16047306/how-is-docker-io-different-from-a-normal-virtual-machine). - -### Do I lose my data when the container exits? - -Not at all! Any data that your application writes to disk gets preserved in its -container until you explicitly delete the container. The file system for the -container persists even after the container halts. - -### How far do Docker containers scale? - -Some of the largest server farms in the world today are based on containers. -Large web deployments like Google and Twitter, and platform providers such as -Heroku run on container technology, at a scale of hundreds of -thousands or even millions of containers. - -### How do I connect Docker containers? - -Currently the recommended way to connect containers is via the Docker network -feature. You can see details of [how to work with Docker networks](../network/drivers/bridge.md). - -### How do I run more than one process in a Docker container? - -This approach is discouraged for most use cases. For maximum efficiency and -isolation, each container should address one specific area of concern. However, -if you need to run multiple services within a single container, see -[Run multiple services in a container](../config/containers/multi-service_container.md). - -### How do I report a security issue with Docker? - -You can learn about the project's security policy -[here](https://www.docker.com/security/) and report security issues to this -[mailbox](mailto:security@docker.com). - -### Why do I need to sign my commits to Docker with the DCO? - -Read [our blog post]( -https://www.docker.com/blog/docker-code-contributions-require-developer-certificate-of-origin/) on the introduction of the DCO. - -### When building an image, should I prefer system libraries or bundled ones? - -*This is a summary of a discussion on the [docker-dev mailing list]( -https://groups.google.com/forum/#!topic/docker-dev/L2RBSPDu1L0).* - -Virtually all programs depend on third-party libraries. Most frequently, they -use dynamic linking and some kind of package dependency, so that when -multiple programs need the same library, it is installed only once. - -Some programs, however, bundle their third-party libraries, because they -rely on very specific versions of those libraries. - -When creating a Docker image, is it better to use the bundled libraries, or -should you build those programs so that they use the default system libraries -instead? - -The key point about system libraries is not about saving disk or memory space. -It is about security. All major distributions handle security seriously, by -having dedicated security teams, following up closely with published -vulnerabilities, and disclosing advisories themselves. (Look at the [Debian -Security Information](https://www.debian.org/security/) -for an example of those procedures.) Upstream developers, however, do not always -implement similar practices. - -Before setting up a Docker image to compile a program from source, if you want -to use bundled libraries, you should check if the upstream authors provide a -convenient way to announce security vulnerabilities, and if they update their -bundled libraries in a timely manner. If they don't, you are exposing yourself -(and the users of your image) to security vulnerabilities. - -Likewise, before using packages built by others, you should check if the -channels providing those packages implement similar security best practices. -Downloading and installing an "all-in-one" .deb or .rpm sounds great at first, -except if you have no way to figure out that it contains a copy of the OpenSSL -library vulnerable to the [Heartbleed](https://heartbleed.com) bug. - -### Why is `DEBIAN_FRONTEND=noninteractive` discouraged in Dockerfiles? - -When building Docker images on Debian and Ubuntu you may have seen errors like: - - unable to initialize frontend: Dialog - -These errors don't stop the image from being built but inform you that the -installation process tried to open a dialog box, but couldn't. Generally, -these errors are safe to ignore. - -Some people circumvent these errors by changing the `DEBIAN_FRONTEND` -environment variable inside the Dockerfile using: - - ENV DEBIAN_FRONTEND=noninteractive - -This prevents the installer from opening dialog boxes during installation which -stops the errors. - -While this may sound like a good idea, it *may* have side effects. The -`DEBIAN_FRONTEND` environment variable is inherited by all images and -containers built from your image, effectively changing their behavior. People -using those images run into problems when installing software -interactively, because installers do not show any dialog boxes. - -Because of this, and because setting `DEBIAN_FRONTEND` to `noninteractive` is -mainly a 'cosmetic' change, we *discourage* changing it. - -If you *really* need to change its setting, make sure to change it back to its -[default value](https://www.debian.org/releases/stable/amd64/ch05s03.en.html#installer-args) -afterwards. - -### Why do I get `Connection reset by peer` when making a request to a service running in a container? - -Typically, this message is returned if the service is already bound to your -localhost. As a result, requests coming to the container from outside are -dropped. To correct this problem, change the service's configuration on your -localhost so that the service accepts requests from all IPs. If you aren't sure -how to do this, check the documentation for your OS. - -### Why do I get `Cannot connect to the Docker daemon. Is the docker daemon running on this host?` when using docker-machine? - -This error points out that the docker client cannot connect to the virtual -machine. This means that either the virtual machine that works underneath -`docker-machine` is not running or that the client doesn't correctly point at -it. - -To verify that the docker machine is running you can use the `docker-machine ls` -command and start it with `docker-machine start` if needed. - - $ docker-machine ls - NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS - default - virtualbox Stopped Unknown - - $ docker-machine start default - -You need to tell Docker to talk to that machine. You can do this with the -`docker-machine env` command. For example, - - $ eval "$(docker-machine env default)" - $ docker ps - -### Where can I find more answers? - -You can find more answers on: - -- [Docker community Slack channel](https://dockr.ly/slack) -- [Docker Support Forums](https://forums.docker.com) -- [GitHub](https://github.com/moby/moby) -- [Ask questions on Stackoverflow](https://stackoverflow.com/search?q=docker) -- [Join the conversation on Twitter](https://twitter.com/docker) diff --git a/content/engine/install/_index.md b/content/engine/install/_index.md deleted file mode 100644 index 47f0716bc8f8..000000000000 --- a/content/engine/install/_index.md +++ /dev/null @@ -1,126 +0,0 @@ ---- -title: Install Docker Engine -description: Learn how to choose the best method for you to install Docker Engine.

You may remove the `experimental` configuration option and continue to use IPv6, if it is not required by any other features. -- `ip6tables` is now enabled for Linux bridge networks by default. [moby/moby#47747](https://github.com/moby/moby/pull/47747) - - This makes IPv4 and IPv6 behaviors consistent with each other, and reduces the risk that IPv6-enabled containers are inadvertently exposed to the network. - - There is no impact if you are running Docker Engine with `ip6tables` enabled (new default). - - If you are using an IPv6-enabled bridge network without `ip6tables`, this is likely a breaking change. Only published container ports (`-p` or `--publish`) are accessible from outside the Docker bridge network, and outgoing connections masquerade as the host. - - To restore the behavior of earlier releases, no `ip6tables` at all, set `"ip6tables": false` in `daemon.json`, or use the CLI option `--ip6tables=false`. Alternatively, leave `ip6tables` enabled, publish ports, and enable direct routing. - - With `ip6tables` enabled, if `ip6tables` is not functional on your host, Docker Engine will start but it will not be possible to create an IPv6-enabled network. - -#### IPv6 network configuration improvements - -- A Unique Local Address (ULA) base prefix is automatically added to `default-address-pools` if this parameter wasn't manually configured, or if it contains no IPv6 prefixes. [moby/moby#47853](https://github.com/moby/moby/pull/47853) - - Prior to this release, to create an IPv6-enabled network it was necessary to use the `--subnet` option to specify an IPv6 subnet, or add IPv6 ranges to `default-address-pools` in `daemon.json`. - - Starting in this release, when a bridge network is created with `--ipv6` and no IPv6 subnet is defined by those options, an IPv6 Unique Local Address (ULA) base prefix is used. - - The ULA prefix is derived from the Engine host ID such that it's unique across hosts and over time. -- IPv6 address pools of any size can now be added to `default-address-pools`. [moby/moby#47768](https://github.com/moby/moby/pull/47768) -- IPv6 can now be enabled by default on all custom bridge networks using `"default-network-opts": { "bridge": {"com.docker.network.enable_ipv6": "true"}}` in `daemon.json`, or `dockerd --default-network-opt=bridge=com.docker.network.enable_ipv6=true`on the comand line. [moby/moby#47867](https://github.com/moby/moby/pull/47867) -- Direct routing for IPv6 networks, with `ip6tables` enabled. [moby/moby#47871](https://github.com/moby/moby/pull/47871) - - Added bridge driver option `com.docker.network.bridge.gateway_mode_ipv6=`. - - The default behavior, `nat`, is unchanged from previous releases running with `ip6tables` enabled. NAT and masquerading rules are set up for each published container port. - - When set to `routed`, no NAT or masquerading rules are configured for published ports.

When you start a container with -`docker run`, behind the scenes Docker creates a set of namespaces and control -groups for the container. - -Namespaces provide the first and most straightforward form of -isolation. Processes running within a container cannot see, and even -less affect, processes running in another container, or in the host -system. - -Each container also gets its own network stack, meaning that a -container doesn't get privileged access to the sockets or interfaces -of another container. Of course, if the host system is setup -accordingly, containers can interact with each other through their -respective network interfaces — just like they can interact with -external hosts. When you specify public ports for your containers or use -[links](../../network/links.md) -then IP traffic is allowed between containers. They can ping each other, -send/receive UDP packets, and establish TCP connections, but that can be -restricted if necessary. From a network architecture point of view, all -containers on a given Docker host are sitting on bridge interfaces. This -means that they are just like physical machines connected through a -common Ethernet switch; no more, no less. - -How mature is the code providing kernel namespaces and private -networking? Kernel namespaces were introduced [between kernel version -2.6.15 and -2.6.26](https://man7.org/linux/man-pages/man7/namespaces.7.html). -This means that since July 2008 (date of the 2.6.26 release -), namespace code has been exercised and scrutinized on a large -number of production systems. And there is more: the design and -inspiration for the namespaces code are even older. Namespaces are -actually an effort to reimplement the features of [OpenVZ]( -https://en.wikipedia.org/wiki/OpenVZ) in such a way that they could be -merged within the mainstream kernel. And OpenVZ was initially released -in 2005, so both the design and the implementation are pretty mature. - -## Control groups - -Control Groups are another key component of Linux containers. They -implement resource accounting and limiting. They provide many -useful metrics, but they also help ensure that each container gets -its fair share of memory, CPU, disk I/O; and, more importantly, that a -single container cannot bring the system down by exhausting one of those -resources. - -So while they do not play a role in preventing one container from -accessing or affecting the data and processes of another container, they -are essential to fend off some denial-of-service attacks. They are -particularly important on multi-tenant platforms, like public and -private PaaS, to guarantee a consistent uptime (and performance) even -when some applications start to misbehave. - -Control Groups have been around for a while as well: the code was -started in 2006, and initially merged in kernel 2.6.24. - -## Docker daemon attack surface - -Running containers (and applications) with Docker implies running the -Docker daemon. This daemon requires `root` privileges unless you opt-in -to [Rootless mode](rootless.md), and you should therefore be aware of -some important details. - -First of all, only trusted users should be allowed to control your -Docker daemon. This is a direct consequence of some powerful Docker -features. Specifically, Docker allows you to share a directory between -the Docker host and a guest container; and it allows you to do so -without limiting the access rights of the container. This means that you -can start a container where the `/host` directory is the `/` directory -on your host; and the container can alter your host filesystem -without any restriction. This is similar to how virtualization systems -allow filesystem resource sharing. Nothing prevents you from sharing your -root filesystem (or even your root block device) with a virtual machine. - -This has a strong security implication: for example, if you instrument Docker -from a web server to provision containers through an API, you should be -even more careful than usual with parameter checking, to make sure that -a malicious user cannot pass crafted parameters causing Docker to create -arbitrary containers. - -For this reason, the REST API endpoint (used by the Docker CLI to -communicate with the Docker daemon) changed in Docker 0.5.2, and now -uses a Unix socket instead of a TCP socket bound on 127.0.0.1 (the -latter being prone to cross-site request forgery attacks if you happen to run -Docker directly on your local machine, outside of a VM). You can then -use traditional Unix permission checks to limit access to the control -socket. - -You can also expose the REST API over HTTP if you explicitly decide to do so. -However, if you do that, be aware of the above mentioned security implications. -Note that even if you have a firewall to limit accesses to the REST API -endpoint from other hosts in the network, the endpoint can be still accessible -from containers, and it can easily result in the privilege escalation. -Therefore it is *mandatory* to secure API endpoints with -[HTTPS and certificates](protect-access.md). -Exposing the daemon API over HTTP without TLS is not permitted, -and such a configuration causes the daemon to fail early on startup, see -[Unauthenticated TCP connections](../deprecated.md#unauthenticated-tcp-connections). -It is also recommended to ensure that it is reachable only from a trusted -network or VPN. - -You can also use `DOCKER_HOST=ssh://USER@HOST` or `ssh -L /path/to/docker.sock:/var/run/docker.sock` -instead if you prefer SSH over TLS. - -The daemon is also potentially vulnerable to other inputs, such as image -loading from either disk with `docker load`, or from the network with -`docker pull`. As of Docker 1.3.2, images are now extracted in a chrooted -subprocess on Linux/Unix platforms, being the first-step in a wider effort -toward privilege separation. As of Docker 1.10.0, all images are stored and -accessed by the cryptographic checksums of their contents, limiting the -possibility of an attacker causing a collision with an existing image. - -Finally, if you run Docker on a server, it is recommended to run -exclusively Docker on the server, and move all other services within -containers controlled by Docker. Of course, it is fine to keep your -favorite admin tools (probably at least an SSH server), as well as -existing monitoring/supervision processes, such as NRPE and collectd. - -## Linux kernel capabilities - -By default, Docker starts containers with a restricted set of -capabilities. What does that mean? - -Capabilities turn the binary "root/non-root" dichotomy into a -fine-grained access control system. Processes (like web servers) that -just need to bind on a port below 1024 do not need to run as root: they -can just be granted the `net_bind_service` capability instead. And there -are many other capabilities, for almost all the specific areas where root -privileges are usually needed. This means a lot for container security. - -Typical servers run several processes as `root`, including the SSH daemon, -`cron` daemon, logging daemons, kernel modules, network configuration tools, -and more. A container is different, because almost all of those tasks are -handled by the infrastructure around the container: - - - SSH access are typically managed by a single server running on - the Docker host - - `cron`, when necessary, should run as a user - process, dedicated and tailored for the app that needs its - scheduling service, rather than as a platform-wide facility - - Log management is also typically handed to Docker, or to - third-party services like Loggly or Splunk - - Hardware management is irrelevant, meaning that you never need to - run `udevd` or equivalent daemons within - containers - - Network management happens outside of the containers, enforcing - separation of concerns as much as possible, meaning that a container - should never need to perform `ifconfig`, - `route`, or ip commands (except when a container - is specifically engineered to behave like a router or firewall, of - course) - -This means that in most cases, containers do not need "real" root -privileges at all* And therefore, containers can run with a reduced -capability set; meaning that "root" within a container has much less -privileges than the real "root". For instance, it is possible to: - - - Deny all "mount" operations - - Deny access to raw sockets (to prevent packet spoofing) - - Deny access to some filesystem operations, like creating new device - nodes, changing the owner of files, or altering attributes (including - the immutable flag) - - Deny module loading - -This means that even if an intruder manages to escalate to root within a -container, it is much harder to do serious damage, or to escalate -to the host. - -This doesn't affect regular web apps, but reduces the vectors of attack by -malicious users considerably. By default Docker -drops all capabilities except [those -needed](https://github.com/moby/moby/blob/master/oci/caps/defaults.go#L6-L19), -an allowlist instead of a denylist approach. You can see a full list of -available capabilities in [Linux -manpages](https://man7.org/linux/man-pages/man7/capabilities.7.html). - -One primary risk with running Docker containers is that the default set -of capabilities and mounts given to a container may provide incomplete -isolation, either independently, or when used in combination with -kernel vulnerabilities. - -Docker supports the addition and removal of capabilities, allowing use -of a non-default profile. This may make Docker more secure through -capability removal, or less secure through the addition of capabilities. -The best practice for users would be to remove all capabilities except -those explicitly required for their processes. - -## Docker Content Trust signature verification - -Docker Engine can be configured to only run signed images. The Docker Content -Trust signature verification feature is built directly into the `dockerd` binary. -This is configured in the Dockerd configuration file. - -To enable this feature, trustpinning can be configured in `daemon.json`, whereby -only repositories signed with a user-specified root key can be pulled and run. - -This feature provides more insight to administrators than previously available with -the CLI for enforcing and performing image signature verification. - -For more information on configuring Docker Content Trust Signature Verification, go to -[Content trust in Docker](trust/index.md). - -## Other kernel security features - -Capabilities are just one of the many security features provided by -modern Linux kernels. It is also possible to leverage existing, -well-known systems like TOMOYO, AppArmor, SELinux, GRSEC, etc. with -Docker. - -While Docker currently only enables capabilities, it doesn't interfere -with the other systems. This means that there are many different ways to -harden a Docker host. Here are a few examples. - - - You can run a kernel with GRSEC and PAX. This adds many safety - checks, both at compile-time and run-time; it also defeats many - exploits, thanks to techniques like address randomization. It doesn't - require Docker-specific configuration, since those security features - apply system-wide, independent of containers. - - If your distribution comes with security model templates for - Docker containers, you can use them out of the box. For instance, we - ship a template that works with AppArmor and Red Hat comes with SELinux - policies for Docker. These templates provide an extra safety net (even - though it overlaps greatly with capabilities). - - You can define your own policies using your favorite access control - mechanism. - -Just as you can use third-party tools to augment Docker containers, including -special network topologies or shared filesystems, tools exist to harden Docker -containers without the need to modify Docker itself. - -As of Docker 1.10 User Namespaces are supported directly by the docker -daemon. This feature allows for the root user in a container to be mapped -to a non uid-0 user outside the container, which can help to mitigate the -risks of container breakout. This facility is available but not enabled -by default. - -Refer to the [daemon command](../../reference/cli/dockerd.md#daemon-user-namespace-options) -in the command line reference for more information on this feature. -Additional information on the implementation of User Namespaces in Docker -can be found in -[this blog post](https://integratedcode.us/2015/10/13/user-namespaces-have-arrived-in-docker/). - -## Conclusions - -Docker containers are, by default, quite secure; especially if you -run your processes as non-privileged users inside the container. - -You can add an extra layer of safety by enabling AppArmor, SELinux, -GRSEC, or another appropriate hardening system. - -If you think of ways to make docker more secure, we welcome feature requests, -pull requests, or comments on the Docker community forums. - -## Related information - -* [Use trusted images](trust/index.md) -* [Seccomp security profiles for Docker](seccomp.md) -* [AppArmor security profiles for Docker](apparmor.md) -* [On the Security of Containers (2014)](https://medium.com/@ewindisch/on-the-security-of-containers-2c60ffe25a9e) -* [Docker swarm mode overlay network security model](../../network/drivers/overlay.md) diff --git a/content/engine/security/https/README.md b/content/engine/security/https/README.md deleted file mode 100644 index 85562d083541..000000000000 --- a/content/engine/security/https/README.md +++ /dev/null @@ -1,32 +0,0 @@ ---- -_build: - list: never - publishResources: false - render: never ---- - -This is an initial attempt to make it easier to test the TLS (HTTPS) examples in the protect-access.md -doc. - -At this point, it is a manual thing, and I've been running it in boot2docker. - -My process is as following: - - $ boot2docker ssh - root@boot2docker:/# git clone https://github.com/moby/moby - root@boot2docker:/# cd docker/docs/articles/https - root@boot2docker:/# make cert - -lots of things to see and manually answer, as openssl wants to be interactive - -> **Note**: make sure you enter the hostname (`boot2docker` in my case) when prompted for `Computer Name`) - - root@boot2docker:/# sudo make run - -Start another terminal: - - $ boot2docker ssh - root@boot2docker:/# cd docker/docs/articles/https - root@boot2docker:/# make client - -The last connects first with `--tls` and then with `--tlsverify`, both should succeed. diff --git a/content/engine/security/rootless.md b/content/engine/security/rootless.md deleted file mode 100644 index 016316b5960f..000000000000 --- a/content/engine/security/rootless.md +++ /dev/null @@ -1,711 +0,0 @@ ---- -description: Run the Docker daemon as a non-root user (Rootless mode) -keywords: security, namespaces, rootless -title: Run the Docker daemon as a non-root user (Rootless mode) ---- - -Rootless mode allows running the Docker daemon and containers as a non-root -user to mitigate potential vulnerabilities in the daemon and -the container runtime. - -Rootless mode does not require root privileges even during the installation of -the Docker daemon, as long as the [prerequisites](#prerequisites) are met. - -## How it works - -Rootless mode executes the Docker daemon and containers inside a user namespace. -This is very similar to [`userns-remap` mode](userns-remap.md), except that -with `userns-remap` mode, the daemon itself is running with root privileges, -whereas in rootless mode, both the daemon and the container are running without -root privileges. - -Rootless mode does not use binaries with `SETUID` bits or file capabilities, -except `newuidmap` and `newgidmap`, which are needed to allow multiple -UIDs/GIDs to be used in the user namespace. - -## Prerequisites - -- You must install `newuidmap` and `newgidmap` on the host.

-## Best practices - -### Rootless Docker in Docker - -To run Rootless Docker inside "rootful" Docker, use the `docker:-dind-rootless` -image instead of `docker:-dind`. - -```console -$ docker run -d --name dind-rootless --privileged docker:25.0-dind-rootless -``` - -The `docker:-dind-rootless` image runs as a non-root user (UID 1000). -However, `--privileged` is required for disabling seccomp, AppArmor, and mount -masks. - -### Expose Docker API socket through TCP -

-```console -$ ssh -l 'echo $DOCKER_HOST' -unix:///run/user/1001/docker.sock -$ docker -H ssh://@ run ... -``` - -### Routing ping packets - -On some distributions, `ping` does not work by default. - -Add `net.ipv4.ping_group_range = 0 2147483647` to `/etc/sysctl.conf` (or -`/etc/sysctl.d`) and run `sudo sysctl --system` to allow using `ping`. - -### Exposing privileged ports - -To expose privileged ports (< 1024), set `CAP_NET_BIND_SERVICE` on `rootlesskit` binary and restart the daemon. - -```console -$ sudo setcap cap_net_bind_service=ep $(which rootlesskit) -$ systemctl --user restart docker -``` - -Or add `net.ipv4.ip_unprivileged_port_start=0` to `/etc/sysctl.conf` (or -`/etc/sysctl.d`) and run `sudo sysctl --system`. - -### Limiting resources - -Limiting resources with cgroup-related `docker run` flags such as `--cpus`, `--memory`, `--pids-limit` -is supported only when running with cgroup v2 and systemd. -See [Changing cgroup version](../../config/containers/runmetrics.md) to enable cgroup v2. - -If `docker info` shows `none` as `Cgroup Driver`, the conditions are not satisfied. -When these conditions are not satisfied, rootless mode ignores the cgroup-related `docker run` flags. -See [Limiting resources without cgroup](#limiting-resources-without-cgroup) for workarounds. - -If `docker info` shows `systemd` as `Cgroup Driver`, the conditions are satisfied. -However, typically, only `memory` and `pids` controllers are delegated to non-root users by default. - -```console -$ cat /sys/fs/cgroup/user.slice/user-$(id -u).slice/user@$(id -u).service/cgroup.controllers -memory pids -``` - -To allow delegation of all controllers, you need to change the systemd configuration as follows: - -```console -# mkdir -p /etc/systemd/system/user@.service.d -# cat > /etc/systemd/system/user@.service.d/delegate.conf << EOF -[Service] -Delegate=cpu cpuset io memory pids -EOF -# systemctl daemon-reload -``` - -> **Note** -> -> Delegating `cpuset` requires systemd 244 or later. - -#### Limiting resources without cgroup - -Even when cgroup is not available, you can still use the traditional `ulimit` and [`cpulimit`](https://github.com/opsengine/cpulimit), -though they work in process-granularity rather than in container-granularity, -and can be arbitrarily disabled by the container process. - -For example: - -- To limit CPU usage to 0.5 cores (similar to `docker run --cpus 0.5`): - `docker run cpulimit --limit=50 --include-children ` -- To limit max VSZ to 64MiB (similar to `docker run --memory 64m`): - `docker run sh -c "ulimit -v 65536; "` - -- To limit max number of processes to 100 per namespaced UID 2000 - (similar to `docker run --pids-limit=100`): - `docker run --user 2000 --ulimit nproc=100 ` -

In -particular, when communicating over an untrusted medium such as the internet, it -is critical to ensure the integrity and the publisher of all the data a system -operates on. You use Docker Engine to push and pull images (data) to a -public or private registry. Content trust gives you the ability to verify both -the integrity and the publisher of all the data received from a registry over -any channel. - -## About Docker Content Trust (DCT) - -Docker Content Trust (DCT) provides the ability to use digital signatures for -data sent to and received from remote Docker registries. These signatures allow -client-side or runtime verification of the integrity and publisher of specific -image tags. - -Through DCT, image publishers can sign their images and image consumers can -ensure that the images they pull are signed. Publishers could be individuals -or organizations manually signing their content or automated software supply -chains signing content as part of their release process. - -### Image tags and DCT - -An individual image record has the following identifier: - -```text -[REGISTRY_HOST[:REGISTRY_PORT]/]REPOSITORY[:TAG] -``` - -A particular image `REPOSITORY` can have multiple tags. For example, `latest` and - `3.1.2` are both tags on the `mongo` image. An image publisher can build an image - and tag combination many times changing the image with each build. - -DCT is associated with the `TAG` portion of an image. Each image repository has -a set of keys that image publishers use to sign an image tag. Image publishers -have discretion on which tags they sign. - -An image repository can contain an image with one tag that is signed and another -tag that is not. For example, consider [the Mongo image -repository](https://hub.docker.com/r/library/mongo/tags/). The `latest` -tag could be unsigned while the `3.1.6` tag could be signed. It is the -responsibility of the image publisher to decide if an image tag is signed or -not. In this representation, some image tags are signed, others are not: - -![Signed tags](images/tag_signing.png) - -Publishers can choose to sign a specific tag or not. As a result, the content of -an unsigned tag and that of a signed tag with the same name may not match. For -example, a publisher can push a tagged image `someimage:latest` and sign it. -Later, the same publisher can push an unsigned `someimage:latest` image. This second -push replaces the last unsigned tag `latest` but does not affect the signed `latest` version. -The ability to choose which tags they can sign, allows publishers to iterate over -the unsigned version of an image before officially signing it. - -Image consumers can enable DCT to ensure that images they use were signed. If a -consumer enables DCT, they can only pull, run, or build with trusted images. -Enabling DCT is a bit like applying a "filter" to your registry. Consumers "see" -only signed image tags and the less desirable, unsigned image tags are -"invisible" to them. - -![Trust view](images/trust_view.png) - -To the consumer who has not enabled DCT, nothing about how they work with Docker -images changes. Every image is visible regardless of whether it is signed or -not. - -### Docker Content Trust Keys - -Trust for an image tag is managed through the use of signing keys. A key set is -created when an operation using DCT is first invoked. A key set consists -of the following classes of keys: - -- An offline key that is the root of DCT for an image tag -- Repository or tagging keys that sign tags -- Server-managed keys such as the timestamp key, which provides freshness - security guarantees for your repository - -The following image depicts the various signing keys and their relationships: - -![Content Trust components](images/trust_components.png) - -> **Warning** -> ->The root key once lost is not recoverable. If you lose any other key, send an email to [Docker Hub Support](mailto:hub-support@docker.com). This loss also requires manual intervention from every -consumer that used a signed tag from this repository prior to the loss. -{ .warning } - -You should back up the root key somewhere safe. Given that it is only required -to create new repositories, it is a good idea to store it offline in hardware. -For details on securing, and backing up your keys, make sure you -read how to [manage keys for DCT](trust_key_mng.md). - -## Signing images with Docker Content Trust - -Within the Docker CLI we can sign and push a container image with the -`$ docker trust` command syntax. This is built on top of the Notary feature -set. For more information, see the [Notary GitHub repository](https://github.com/theupdateframework/notary). - -A prerequisite for signing an image is a Docker Registry with a Notary server -attached (Such as the Docker Hub ). Instructions for -standing up a self-hosted environment can be found [here](/engine/security/trust/deploying_notary/). - -To sign a Docker Image you will need a delegation key pair. These keys -can be generated locally using `$ docker trust key generate` or generated -by a certificate authority. - -First we will add the delegation private key to the local Docker trust -repository. (By default this is stored in `~/.docker/trust/`). If you are -generating delegation keys with `$ docker trust key generate`, the private key -is automatically added to the local trust store. If you are importing a separate -key, you will need to use the -`$ docker trust key load` command. - -```console -$ docker trust key generate jeff -Generating key for jeff... -Enter passphrase for new jeff key with ID 9deed25: -Repeat passphrase for new jeff key with ID 9deed25: -Successfully generated and loaded private key. Corresponding public key available: /home/ubuntu/Documents/mytrustdir/jeff.pub -``` - -Or if you have an existing key: - -```console -$ docker trust key load key.pem --name jeff -Loading key from "key.pem"... -Enter passphrase for new jeff key with ID 8ae710e: -Repeat passphrase for new jeff key with ID 8ae710e: -Successfully imported key from key.pem -``` - -Next we will need to add the delegation public key to the Notary server; -this is specific to a particular image repository in Notary known as a Global -Unique Name (GUN). If this is the first time you are adding a delegation to that -repository, this command will also initiate the repository, using a local Notary -canonical root key.

Use the Docker CLI to create a swarm, deploy -application services to a swarm, and manage swarm behavior. - -Docker Swarm mode is built into the Docker Engine. Do not confuse Docker Swarm mode -with [Docker Classic Swarm](https://github.com/docker/classicswarm) -which is no longer actively developed. - -## Feature highlights - -### Cluster management integrated with Docker Engine - -Use the Docker Engine CLI to create a swarm of Docker Engines where you can deploy application -services. You don't need additional orchestration software to create or manage -a swarm. - -### Decentralized design - -Instead of handling differentiation between node roles at deployment time, the Docker Engine handles any specialization at runtime. You can deploy both kinds of nodes, managers and workers, using the -Docker Engine. This means you can build an entire swarm from a single disk -image. - -### Declarative service model - -Docker Engine uses a declarative approach to -let you define the desired state of the various services in your application -stack. For example, you might describe an application comprised of a web front -end service with message queueing services and a database backend. - -### Scaling - -For each service, you can declare the number of tasks you want to -run. When you scale up or down, the swarm manager automatically adapts by -adding or removing tasks to maintain the desired state. - -### Desired state reconciliation - -The swarm manager node constantly monitors -the cluster state and reconciles any differences between the actual state and your -expressed desired state. For example, if you set up a service to run 10 -replicas of a container, and a worker machine hosting two of those replicas -crashes, the manager creates two new replicas to replace the replicas that -crashed. The swarm manager assigns the new replicas to workers that are -running and available. - -### Multi-host networking - -You can specify an overlay network for your -services. The swarm manager automatically assigns addresses to the containers -on the overlay network when it initializes or updates the application. - -### Service discovery - -Swarm manager nodes assign each service in the swarm a -unique DNS name and load balance running containers. You can query every -container running in the swarm through a DNS server embedded in the swarm. - -### Load balancing - -You can expose the ports for services to an -external load balancer. Internally, the swarm lets you specify how to distribute -service containers between nodes. - -### Secure by default - -Each node in the swarm enforces TLS mutual -authentication and encryption to secure communications between itself and all -other nodes. You have the option to use self-signed root certificates or -certificates from a custom root CA. - -### Rolling updates - -At rollout time you can apply service updates to nodes -incrementally. The swarm manager lets you control the delay between service -deployment to different sets of nodes. If anything goes wrong, you can -roll back to a previous version of the service. - -## What's next? - -* Learn Swarm mode [key concepts](key-concepts.md). -* Get started with the [Swarm mode tutorial](swarm-tutorial/index.md). -* Explore Swarm mode CLI commands - * [swarm init](../../reference/cli/docker/swarm/init.md) - * [swarm join](../../reference/cli/docker/swarm/join.md) - * [service create](../../reference/cli/docker/service/create.md) - * [service inspect](../../reference/cli/docker/service/inspect.md) - * [service ls](../../reference/cli/docker/service/ls.md) - * [service rm](../../reference/cli/docker/service/rm.md) - * [service scale](../../reference/cli/docker/service/scale.md) - * [service ps](../../reference/cli/docker/service/ps.md) - * [service update](../../reference/cli/docker/service/update.md) \ No newline at end of file diff --git a/content/engine/swarm/configs.md b/content/engine/swarm/configs.md deleted file mode 100644 index cfccca7eb364..000000000000 --- a/content/engine/swarm/configs.md +++ /dev/null @@ -1,668 +0,0 @@ ---- -title: Store configuration data using Docker Configs -description: How to store configuration data separate from the runtime -keywords: swarm, configuration, configs ---- - -## About configs - -Docker swarm service configs allow you to store non-sensitive information, -such as configuration files, outside a service's image or running containers. -This allows you to keep your images as generic as possible, without the need to -bind-mount configuration files into the containers or use environment variables. - -Configs operate in a similar way to [secrets](secrets.md), except that they are -not encrypted at rest and are mounted directly into the container's filesystem -without the use of RAM disks. Configs can be added or removed from a service at -any time, and services can share a config. You can even use configs in -conjunction with environment variables or labels, for maximum flexibility. -Config values can be generic strings or binary content (up to 500 kb in size). - -> **Note** -> -> Docker configs are only available to swarm services, not to -> standalone containers. To use this feature, consider adapting your container -> to run as a service with a scale of 1. - -Configs are supported on both Linux and Windows services. - -### Windows support - -Docker includes support for configs on Windows containers, but there are differences -in the implementations, which are called out in the examples below. Keep the -following notable differences in mind: - -- Config files with custom targets are not directly bind-mounted into Windows - containers, since Windows does not support non-directory file bind-mounts. - Instead, configs for a container are all mounted in - `C:\ProgramData\Docker\internal\configs` (an implementation detail which - should not be relied upon by applications) within the container. Symbolic - links are used to point from there to the desired target of the config within - the container. The default target is `C:\ProgramData\Docker\configs`. - -- When creating a service which uses Windows containers, the options to specify - UID, GID, and mode are not supported for configs. Configs are currently only - accessible by administrators and users with `system` access within the - container. - -- On Windows, create or update a service using `--credential-spec` with the - `config://` format. This passes the gMSA credentials file - directly to nodes before a container starts. No gMSA credentials are written - to disk on worker nodes. For more information, refer to - [Deploy services to a swarm](services.md#gmsa-for-swarm). - -## How Docker manages configs - -When you add a config to the swarm, Docker sends the config to the swarm manager -over a mutual TLS connection. The config is stored in the Raft log, which is -encrypted. The entire Raft log is replicated across the other managers, ensuring -the same high availability guarantees for configs as for the rest of the swarm -management data. - -When you grant a newly-created or running service access to a config, the config -is mounted as a file in the container. The location of the mount point within -the container defaults to `/` in Linux containers. In Windows -containers, configs are all mounted into `C:\ProgramData\Docker\configs` and -symbolic links are created to the desired location, which defaults to -`C:\`. - -You can set the ownership (`uid` and `gid`) for the config, using either the -numerical ID or the name of the user or group. You can also specify the file -permissions (`mode`). These settings are ignored for Windows containers. - -- If not set, the config is owned by the user running the container - command (often `root`) and that user's default group (also often `root`). -- If not set, the config has world-readable permissions (mode `0444`), unless a - `umask` is set within the container, in which case the mode is impacted by - that `umask` value. - -You can update a service to grant it access to additional configs or revoke its -access to a given config at any time. - -A node only has access to configs if the node is a swarm manager or if it is -running service tasks which have been granted access to the config. When a -container task stops running, the configs shared to it are unmounted from the -in-memory filesystem for that container and flushed from the node's memory. - -If a node loses connectivity to the swarm while it is running a task container -with access to a config, the task container still has access to its configs, but -cannot receive updates until the node reconnects to the swarm. - -You can add or inspect an individual config at any time, or list all -configs. You cannot remove a config that a running service is -using. See [Rotate a config](configs.md#example-rotate-a-config) for a way to -remove a config without disrupting running services. - -To update or roll back configs more easily, consider adding a version -number or date to the config name. This is made easier by the ability to control -the mount point of the config within a given container. - -To update a stack, make changes to your Compose file, then re-run `docker -stack deploy -c `. If you use a new config in -that file, your services start using them. Keep in mind that configurations -are immutable, so you can't change the file for an existing service. -Instead, you create a new config to use a different file - -You can run `docker stack rm` to stop the app and take down the stack. This -removes any config that was created by `docker stack deploy` with the same stack -name. This removes _all_ configs, including those not referenced by services and -those remaining after a `docker service update --config-rm`. - -## Read more about `docker config` commands - -Use these links to read about specific commands, or continue to the -[example about using configs with a service](#advanced-example-use-configs-with-a-nginx-service). - -- [`docker config create`](../../reference/cli/docker/config/create.md) -- [`docker config inspect`](../../reference/cli/docker/config/inspect.md) -- [`docker config ls`](../../reference/cli/docker/config/ls.md) -- [`docker config rm`](../../reference/cli/docker/config/rm.md) - -## Examples - -This section includes graduated examples which illustrate how to use -Docker configs. - -> **Note** -> -> These examples use a single-engine swarm and unscaled services for -> simplicity.

For a -real-world example, continue to -[Advanced example: Use configs with a Nginx service](#advanced-example-use-configs-with-a-nginx-service). - -1. Add a config to Docker. The `docker config create` command reads standard - input because the last argument, which represents the file to read the - config from, is set to `-`. - - ```console - $ echo "This is a config" | docker config create my-config - - ``` - -2. Create a `redis` service and grant it access to the config. By default, - the container can access the config at `/my-config`, but - you can customize the file name on the container using the `target` option. - - ```console - $ docker service create --name redis --config my-config redis:alpine - ``` - -3. Verify that the task is running without issues using `docker service ps`. If - everything is working, the output looks similar to this: - - ```console - $ docker service ps redis - - ID NAME IMAGE NODE DESIRED STATE CURRENT STATE ERROR PORTS - bkna6bpn8r1a redis.1 redis:alpine ip-172-31-46-109 Running Running 8 seconds ago - ``` - -4. Get the ID of the `redis` service task container using `docker ps`, so that - you can use `docker container exec` to connect to the container and read the contents - of the config data file, which defaults to being readable by all and has the - same name as the name of the config. The first command below illustrates - how to find the container ID, and the second and third commands use shell - completion to do this automatically. - - ```console - $ docker ps --filter name=redis -q - - 5cb1c2348a59 - - $ docker container exec $(docker ps --filter name=redis -q) ls -l /my-config - - -r--r--r-- 1 root root 12 Jun 5 20:49 my-config - - $ docker container exec $(docker ps --filter name=redis -q) cat /my-config - - This is a config - ``` - -5. Try removing the config. The removal fails because the `redis` service is - running and has access to the config. - - ```console - - $ docker config ls - - ID NAME CREATED UPDATED - fzwcfuqjkvo5foqu7ts7ls578 hello 31 minutes ago 31 minutes ago - - - $ docker config rm my-config - - Error response from daemon: rpc error: code = 3 desc = config 'my-config' is - in use by the following service: redis - ``` - -6. Remove access to the config from the running `redis` service by updating the - service. - - ```console - $ docker service update --config-rm my-config redis - ``` - -7. Repeat steps 3 and 4 again, verifying that the service no longer has access - to the config. The container ID is different, because the - `service update` command redeploys the service. - - ```none - $ docker container exec -it $(docker ps --filter name=redis -q) cat /my-config - - cat: can't open '/my-config': No such file or directory - ``` - -8. Stop and remove the service, and remove the config from Docker. - - ```console - $ docker service rm redis - - $ docker config rm my-config - ``` - -### Simple example: Use configs in a Windows service - -This is a very simple example which shows how to use configs with a Microsoft -IIS service running on Docker for Windows running Windows containers on -Microsoft Windows 10. It is a naive example that stores the webpage in a config. - -This example assumes that you have PowerShell installed. - -1. Save the following into a new file `index.html`. - - ```html - - Hello Docker - -

Hello Docker! You have deployed a HTML page.

- - - ``` - -2. If you have not already done so, initialize or join the swarm. - - ```powershell - docker swarm init - ``` - -3. Save the `index.html` file as a swarm config named `homepage`. - - ```powershell - docker config create homepage index.html - ``` - -4. Create an IIS service and grant it access to the `homepage` config. - - ```powershell - docker service create - --name my-iis - --publish published=8000,target=8000 - --config src=homepage,target="\inetpub\wwwroot\index.html" - microsoft/iis:nanoserver - ``` - -5. Access the IIS service at `http://localhost:8000/`. It should serve - the HTML content from the first step. - -6. Remove the service and the config. - - ```powershell - docker service rm my-iis - - docker config rm homepage - ``` - -### Example: Use a templated config - -To create a configuration in which the content will be generated using a -template engine, use the `--template-driver` parameter and specify the engine -name as its argument. The template will be rendered when container is created. - -1. Save the following into a new file `index.html.tmpl`. - - ```html - - Hello Docker - -

Hello {{ env "HELLO" }}! I'm service {{ .Service.Name }}.

- - - ``` - -2. Save the `index.html.tmpl` file as a swarm config named `homepage`. Provide - parameter `--template-driver` and specify `golang` as template engine. - - ```console - $ docker config create --template-driver golang homepage index.html.tmpl - ``` - -3. Create a service that runs Nginx and has access to the environment variable - HELLO and to the config. - - ```console - $ docker service create \ - --name hello-template \ - --env HELLO="Docker" \ - --config source=homepage,target=/usr/share/nginx/html/index.html \ - --publish published=3000,target=80 \ - nginx:alpine - ``` - -4. Verify that the service is operational: you can reach the Nginx server, and - that the correct output is being served. - - ```console - $ curl http://0.0.0.0:3000 - - - Hello Docker - -

Hello Docker! I'm service hello-template.

- - - ``` - -### Advanced example: Use configs with a Nginx service - -This example is divided into two parts. -[The first part](#generate-the-site-certificate) is all about generating -the site certificate and does not directly involve Docker configs at all, but -it sets up [the second part](#configure-the-nginx-container), where you store -and use the site certificate as a series of secrets and the Nginx configuration -as a config. The example shows how to set options on the config, such as the -target location within the container and the file permissions (`mode`). - -#### Generate the site certificate - -Generate a root CA and TLS certificate and key for your site. For production -sites, you may want to use a service such as `Let’s Encrypt` to generate the -TLS certificate and key, but this example uses command-line tools. This step -is a little complicated, but is only a set-up step so that you have -something to store as a Docker secret. If you want to skip these sub-steps, -you can [use Let's Encrypt](https://letsencrypt.org/getting-started/) to -generate the site key and certificate, name the files `site.key` and -`site.crt`, and skip to -[Configure the Nginx container](#configure-the-nginx-container). - -1. Generate a root key. - - ```console - $ openssl genrsa -out "root-ca.key" 4096 - ``` - -2. Generate a CSR using the root key. - - ```console - $ openssl req \ - -new -key "root-ca.key" \ - -out "root-ca.csr" -sha256 \ - -subj '/C=US/ST=CA/L=San Francisco/O=Docker/CN=Swarm Secret Example CA' - ``` - -3. Configure the root CA. Edit a new file called `root-ca.cnf` and paste - the following contents into it. This constrains the root CA to only sign - leaf certificates and not intermediate CAs. - - ```none - [root_ca] - basicConstraints = critical,CA:TRUE,pathlen:1 - keyUsage = critical, nonRepudiation, cRLSign, keyCertSign - subjectKeyIdentifier=hash - ``` - -4. Sign the certificate. - - ```console - $ openssl x509 -req -days 3650 -in "root-ca.csr" \ - -signkey "root-ca.key" -sha256 -out "root-ca.crt" \ - -extfile "root-ca.cnf" -extensions \ - root_ca - ``` - -5. Generate the site key. - - ```console - $ openssl genrsa -out "site.key" 4096 - ``` - -6. Generate the site certificate and sign it with the site key. - - ```console - $ openssl req -new -key "site.key" -out "site.csr" -sha256 \ - -subj '/C=US/ST=CA/L=San Francisco/O=Docker/CN=localhost' - ``` - -7. Configure the site certificate. Edit a new file called `site.cnf` and - paste the following contents into it. This constrains the site - certificate so that it can only be used to authenticate a server and - can't be used to sign certificates. - - ```none - [server] - authorityKeyIdentifier=keyid,issuer - basicConstraints = critical,CA:FALSE - extendedKeyUsage=serverAuth - keyUsage = critical, digitalSignature, keyEncipherment - subjectAltName = DNS:localhost, IP:127.0.0.1 - subjectKeyIdentifier=hash - ``` - -8. Sign the site certificate. - - ```console - $ openssl x509 -req -days 750 -in "site.csr" -sha256 \ - -CA "root-ca.crt" -CAkey "root-ca.key" -CAcreateserial \ - -out "site.crt" -extfile "site.cnf" -extensions server - ``` - -9. The `site.csr` and `site.cnf` files are not needed by the Nginx service, but - you need them if you want to generate a new site certificate. Protect - the `root-ca.key` file. - -#### Configure the Nginx container - -1. Produce a very basic Nginx configuration that serves static files over HTTPS. - The TLS certificate and key are stored as Docker secrets so that they - can be rotated easily. - - In the current directory, create a new file called `site.conf` with the - following contents: - - ```none - server { - listen 443 ssl; - server_name localhost; - ssl_certificate /run/secrets/site.crt; - ssl_certificate_key /run/secrets/site.key; - - location / { - root /usr/share/nginx/html; - index index.html index.htm; - } - } - ``` - -2. Create two secrets, representing the key and the certificate. You can store - any file as a secret as long as it is smaller than 500 KB. This allows you - to decouple the key and certificate from the services that use them. - In these examples, the secret name and the file name are the same. - - ```console - $ docker secret create site.key site.key - - $ docker secret create site.crt site.crt - ``` - -3. Save the `site.conf` file in a Docker config. The first parameter is the - name of the config, and the second parameter is the file to read it from. - - ```console - $ docker config create site.conf site.conf - ``` - - List the configs: - - ```console - $ docker config ls - - ID NAME CREATED UPDATED - 4ory233120ccg7biwvy11gl5z site.conf 4 seconds ago 4 seconds ago - ``` - - -4. Create a service that runs Nginx and has access to the two secrets and the - config. Set the mode to `0440` so that the file is only readable by its - owner and that owner's group, not the world. - - ```console - $ docker service create \ - --name nginx \ - --secret site.key \ - --secret site.crt \ - --config source=site.conf,target=/etc/nginx/conf.d/site.conf,mode=0440 \ - --publish published=3000,target=443 \ - nginx:latest \ - sh -c "exec nginx -g 'daemon off;'" - ``` - - Within the running containers, the following three files now exist: - - - `/run/secrets/site.key` - - `/run/secrets/site.crt` - - `/etc/nginx/conf.d/site.conf` - -5. Verify that the Nginx service is running. - - ```console - $ docker service ls - - ID NAME MODE REPLICAS IMAGE - zeskcec62q24 nginx replicated 1/1 nginx:latest - - $ docker service ps nginx - - NAME IMAGE NODE DESIRED STATE CURRENT STATE ERROR PORTS - nginx.1.9ls3yo9ugcls nginx:latest moby Running Running 3 minutes ago - ``` - -6. Verify that the service is operational: you can reach the Nginx - server, and that the correct TLS certificate is being used. - - ```console - $ curl --cacert root-ca.crt https://0.0.0.0:3000 - - - - - Welcome to nginx! - - - -

When you declare a -desired service state by creating or updating a service, the orchestrator -realizes the desired state by scheduling tasks. For instance, you define a -service that instructs the orchestrator to keep three instances of an HTTP -listener running at all times. The orchestrator responds by creating three -tasks. Each task is a slot that the scheduler fills by spawning a container. The -container is the instantiation of the task. If an HTTP listener task subsequently -fails its health check or crashes, the orchestrator creates a new replica task -that spawns a new container. - -A task is a one-directional mechanism. It progresses monotonically through a -series of states: assigned, prepared, running, etc. If the task fails, the -orchestrator removes the task and its container and then creates a new task to -replace it according to the desired state specified by the service. - -The underlying logic of Docker's Swarm mode is a general purpose scheduler and -orchestrator. The service and task abstractions themselves are unaware of the -containers they implement. Hypothetically, you could implement other types of -tasks such as virtual machine tasks or non-containerized process tasks. The -scheduler and orchestrator are agnostic about the type of the task. However, the -current version of Docker only supports container tasks. - -The diagram below shows how Swarm mode accepts service create requests and -schedules tasks to worker nodes. - -![Services flow](../images/service-lifecycle.webp?w=700) - -### Pending services - -A service may be configured in such a way that no node currently in the -swarm can run its tasks. In this case, the service remains in state `pending`. -Here are a few examples of when a service might remain in state `pending`. - -> **Tip** -> If your only intention is to prevent a service from -> being deployed, scale the service to 0 instead of trying to configure it in -> such a way that it remains in `pending`. -{ .tip } - -- If all nodes are paused or drained, and you create a service, it is - pending until a node becomes available. In reality, the first node to become - available gets all of the tasks, so this is not a good thing to do in a - production environment. - -- You can reserve a specific amount of memory for a service. If no node in the - swarm has the required amount of memory, the service remains in a pending - state until a node is available which can run its tasks. If you specify a very - large value, such as 500 GB, the task stays pending forever, unless you - really have a node which can satisfy it. - -- You can impose placement constraints on the service, and the constraints may - not be able to be honored at a given time. - -This behavior illustrates that the requirements and configuration of your tasks -are not tightly tied to the current state of the swarm.

For a full list of configurable options, run the -command `docker network create --help`. The following are some of the most -common options to change. - -#### Configure the subnet and gateway - -By default, the network's subnet and gateway are configured automatically when -the first service is connected to the network. You can configure these when -creating a network using the `--subnet` and `--gateway` flags. The following -example extends the previous one by configuring the subnet and gateway. - -```console -$ docker network create \ - --driver overlay \ - --subnet 10.0.9.0/24 \ - --gateway 10.0.9.99 \ - my-network -``` - -##### Using custom default address pools - -To customize subnet allocation for your Swarm networks, you can [optionally configure them](swarm-mode.md) during `swarm init`. - -For example, the following command is used when initializing Swarm: - -```console -$ docker swarm init --default-addr-pool 10.20.0.0/16 --default-addr-pool-mask-length 26 -``` - -Whenever a user creates a network, but does not use the `--subnet` command line option, the subnet for this network will be allocated sequentially from the next available subnet from the pool. If the specified network is already allocated, that network will not be used for Swarm. - -Multiple pools can be configured if discontiguous address space is required. However, allocation from specific pools is not supported. Network subnets will be allocated sequentially from the IP pool space and subnets will be reused as they are deallocated from networks that are deleted. - -The default mask length can be configured and is the same for all networks. It is set to `/24` by default. To change the default subnet mask length, use the `--default-addr-pool-mask-length` command line option. - -> **Note** -> -> Default address pools can only be configured on `swarm init` and cannot be altered after cluster creation. - -##### Overlay network size limitations - -Docker recommends creating overlay networks with `/24` blocks. The `/24` overlay network blocks limit the network to 256 IP addresses. - -This recommendation addresses [limitations with swarm mode](https://github.com/moby/moby/issues/30820). -If you need more than 256 IP addresses, do not increase the IP block size. You can either use `dnsrr` -endpoint mode with an external load balancer, or use multiple smaller overlay networks. See -[Configure service discovery](#configure-service-discovery) for more information about different endpoint modes. - -#### Configure encryption of application data {#encryption} - -Management and control plane data related to a swarm is always encrypted. -For more details about the encryption mechanisms, see the -[Docker swarm mode overlay network security model](../../network/drivers/overlay.md). - -Application data among swarm nodes is not encrypted by default. To encrypt this -traffic on a given overlay network, use the `--opt encrypted` flag on `docker -network create`. This enables IPSEC encryption at the level of the vxlan. This -encryption imposes a non-negligible performance penalty, so you should test this -option before using it in production. - -> **Note** -> -> You must [customize the automatically created ingress](#customize-ingress) -> to enable encryption. By default, all ingress traffic is unencrypted, as encryption -> is a network-level option. - -## Attach a service to an overlay network - -To attach a service to an existing overlay network, pass the `--network` flag to -`docker service create`, or the `--network-add` flag to `docker service update`. - -```console -$ docker service create \ - --replicas 3 \ - --name my-web \ - --network my-network \ - nginx -``` - -Service containers connected to an overlay network can communicate with -each other across it. - -To see which networks a service is connected to, use `docker service ls` to find -the name of the service, then `docker service ps ` to list the -networks. Alternately, to see which services' containers are connected to a -network, use `docker network inspect `. You can run these commands -from any swarm node which is joined to the swarm and is in a `running` state. - -### Configure service discovery - -Service discovery is the mechanism Docker uses to route a request from your -service's external clients to an individual swarm node, without the client -needing to know how many nodes are participating in the service or their -IP addresses or ports. You don't need to publish ports which are used between -services on the same network. For instance, if you have a -[WordPress service that stores its data in a MySQL service](https://training.play-with-docker.com/swarm-service-discovery/), -and they are connected to the same overlay network, you do not need to publish -the MySQL port to the client, only the WordPress HTTP port. - -Service discovery can work in two different ways: internal connection-based -load-balancing at Layers 3 and 4 using the embedded DNS and a virtual IP (VIP), -or external and customized request-based load-balancing at Layer 7 using DNS -round robin (DNSRR). You can configure this per service. - -- By default, when you attach a service to a network and that service publishes - one or more ports, Docker assigns the service a virtual IP (VIP), which is the - "front end" for clients to reach the service. Docker keeps a list of all - worker nodes in the service, and routes requests between the client and one of - the nodes. Each request from the client might be routed to a different node. - -- If you configure a service to use DNS round-robin (DNSRR) service discovery, - there is not a single virtual IP. Instead, Docker sets up DNS entries for the - service such that a DNS query for the service name returns a list of IP - addresses, and the client connects directly to one of these. - - DNS round-robin is useful in cases where you want to use your own load - balancer, such as HAProxy. To configure a service to use DNSRR, use the flag - `--endpoint-mode dnsrr` when creating a new service or updating an existing - one. - -## Customize the ingress network {#customize-ingress} - -Most users never need to configure the `ingress` network, but Docker allows you -to do so. This can be useful if the automatically-chosen subnet -conflicts with one that already exists on your network, or you need to customize -other low-level network settings such as the MTU, or if you want to -[enable encryption](#encryption). - -Customizing the `ingress` network involves removing and recreating it. This is -usually done before you create any services in the swarm. If you have existing -services which publish ports, those services need to be removed before you can -remove the `ingress` network. - -During the time that no `ingress` network exists, existing services which do not -publish ports continue to function but are not load-balanced. This affects -services which publish ports, such as a WordPress service which publishes port -80. - -1. Inspect the `ingress` network using `docker network inspect ingress`, and - remove any services whose containers are connected to it. These are services - that publish ports, such as a WordPress service which publishes port 80. If - all such services are not stopped, the next step fails. - -2. Remove the existing `ingress` network: - - ```console - $ docker network rm ingress - - WARNING! Before removing the routing-mesh network, make sure all the nodes - in your swarm run the same docker engine version. Otherwise, removal may not - be effective and functionality of newly created ingress networks will be - impaired. - Are you sure you want to continue? [y/N] - ``` - -3. Create a new overlay network using the `--ingress` flag, along with the - custom options you want to set. This example sets the MTU to 1200, sets - the subnet to `10.11.0.0/16`, and sets the gateway to `10.11.0.2`. - - ```console - $ docker network create \ - --driver overlay \ - --ingress \ - --subnet=10.11.0.0/16 \ - --gateway=10.11.0.2 \ - --opt com.docker.network.driver.mtu=1200 \ - my-ingress - ``` - - > **Note** - > - > You can name your `ingress` network something other than - > `ingress`, but you can only have one. An attempt to create a second one - > fails. - -4. Restart the services that you stopped in the first step. - -## Customize the docker_gwbridge - -The `docker_gwbridge` is a virtual bridge that connects the overlay networks -(including the `ingress` network) to an individual Docker daemon's physical -network. Docker creates it automatically when you initialize a swarm or join a -Docker host to a swarm, but it is not a Docker device. It exists in the kernel -of the Docker host. If you need to customize its settings, you must do so before -joining the Docker host to the swarm, or after temporarily removing the host -from the swarm. - -You need to have the `brctl` application installed on your operating system in -order to delete an existing bridge. The package name is `bridge-utils`. - -1. Stop Docker. - -2. Use the `brctl show docker_gwbridge` command to check whether a bridge - device exists called `docker_gwbridge`. If so, remove it using - `brctl delbr docker_gwbridge`. - -3. Start Docker. Do not join or initialize the swarm. - -4. Create or re-create the `docker_gwbridge` bridge with your custom settings. - This example uses the subnet `10.11.0.0/16`. For a full list of customizable - options, see [Bridge driver options](../../reference/cli/docker/network/create.md#bridge-driver-options). - - ```console - $ docker network create \ - --subnet 10.11.0.0/16 \ - --opt com.docker.network.bridge.name=docker_gwbridge \ - --opt com.docker.network.bridge.enable_icc=false \ - --opt com.docker.network.bridge.enable_ip_masquerade=true \ - docker_gwbridge - ``` - -5. Initialize or join the swarm. - -## Use a separate interface for control and data traffic - -By default, all swarm traffic is sent over the same interface, including control -and management traffic for maintaining the swarm itself and data traffic to and -from the service containers. - -You can separate this traffic by passing -the `--data-path-addr` flag when initializing or joining the swarm. If there are -multiple interfaces, `--advertise-addr` must be specified explicitly, and -`--data-path-addr` defaults to `--advertise-addr` if not specified. Traffic about -joining, leaving, and managing the swarm is sent over the -`--advertise-addr` interface, and traffic among a service's containers is sent -over the `--data-path-addr` interface. These flags can take an IP address or -a network device name, such as `eth0`. - -This example initializes a swarm with a separate `--data-path-addr`. It assumes -that your Docker host has two different network interfaces: 10.0.0.1 should be -used for control and management traffic and 192.168.0.1 should be used for -traffic relating to services. - -```console -$ docker swarm init --advertise-addr 10.0.0.1 --data-path-addr 192.168.0.1 -``` - -This example joins the swarm managed by host `192.168.99.100:2377` and sets the -`--advertise-addr` flag to `eth0` and the `--data-path-addr` flag to `eth1`. - -```console -$ docker swarm join \ - --token SWMTKN-1-49nj1cmql0jkz5s954yi3oex3nedyz0fb0xx14ie39trti4wxv-8vxv8rssmk743ojnwacrr2d7c \ - --advertise-addr eth0 \ - --data-path-addr eth1 \ - 192.168.99.100:2377 -``` - -## Publish ports on an overlay network - -Swarm services connected to the same overlay network effectively expose all -ports to each other. For a port to be accessible outside of the service, that -port must be _published_ using the `-p` or `--publish` flag on `docker service -create` or `docker service update`. Both the legacy colon-separated syntax and -the newer comma-separated value syntax are supported. The longer syntax is -preferred because it is somewhat self-documenting. - - - - - - - - - - - - - - - - - - - - -

You can use Docker _secrets_ to centrally manage -this data and securely transmit it to only those containers that need access to -it. Secrets are encrypted during transit and at rest in a Docker swarm. A given -secret is only accessible to those services which have been granted explicit -access to it, and only while those service tasks are running. - -You can use secrets to manage any sensitive data which a container needs at -runtime but you don't want to store in the image or in source control, such as: - -- Usernames and passwords -- TLS certificates and keys -- SSH keys -- Other important data such as the name of a database or internal server -- Generic strings or binary content (up to 500 kb in size) - -> **Note** -> -> Docker secrets are only available to swarm services, not to -> standalone containers. To use this feature, consider adapting your container -> to run as a service. Stateful containers can typically run with a scale of 1 -> without changing the container code. - -Another use case for using secrets is to provide a layer of abstraction between -the container and a set of credentials. Consider a scenario where you have -separate development, test, and production environments for your application. -Each of these environments can have different credentials, stored in the -development, test, and production swarms with the same secret name. Your -containers only need to know the name of the secret to function in all -three environments. - -You can also use secrets to manage non-sensitive data, such as configuration -files. However, Docker supports the use of [configs](configs.md) -for storing non-sensitive data. Configs are mounted into the container's -filesystem directly, without the use of a RAM disk. - -### Windows support - -Docker includes support for secrets on Windows containers. Where there are -differences in the implementations, they are called out in the -examples below. Keep the following notable differences in mind: - -- Microsoft Windows has no built-in driver for managing RAM disks, so within - running Windows containers, secrets are persisted in clear text to the - container's root disk. However, the secrets are explicitly removed when a - container stops. In addition, Windows does not support persisting a running - container as an image using `docker commit` or similar commands. - -- On Windows, we recommend enabling - [BitLocker](https://technet.microsoft.com/en-us/library/cc732774(v=ws.11).aspx) - on the volume containing the Docker root directory on the host machine to - ensure that secrets for running containers are encrypted at rest. - -- Secret files with custom targets are not directly bind-mounted into Windows - containers, since Windows does not support non-directory file bind-mounts. - Instead, secrets for a container are all mounted in - `C:\ProgramData\Docker\internal\secrets` (an implementation detail which - should not be relied upon by applications) within the container. Symbolic - links are used to point from there to the desired target of the secret within - the container. The default target is `C:\ProgramData\Docker\secrets`. - -- When creating a service which uses Windows containers, the options to specify - UID, GID, and mode are not supported for secrets. Secrets are currently only - accessible by administrators and users with `system` access within the - container. - -## How Docker manages secrets - -When you add a secret to the swarm, Docker sends the secret to the swarm manager -over a mutual TLS connection. The secret is stored in the Raft log, which is -encrypted. The entire Raft log is replicated across the other managers, ensuring -the same high availability guarantees for secrets as for the rest of the swarm -management data. - -When you grant a newly-created or running service access to a secret, the -decrypted secret is mounted into the container in an in-memory filesystem. The -location of the mount point within the container defaults to -`/run/secrets/` in Linux containers, or -`C:\ProgramData\Docker\secrets` in Windows containers. You can also specify a -custom location. - -You can update a service to grant it access to additional secrets or revoke its -access to a given secret at any time. - -A node only has access to (encrypted) secrets if the node is a swarm manager or -if it is running service tasks which have been granted access to the secret. -When a container task stops running, the decrypted secrets shared to it are -unmounted from the in-memory filesystem for that container and flushed from the -node's memory. - -If a node loses connectivity to the swarm while it is running a task container -with access to a secret, the task container still has access to its secrets, but -cannot receive updates until the node reconnects to the swarm. - -You can add or inspect an individual secret at any time, or list all -secrets. You cannot remove a secret that a running service is -using. See [Rotate a secret](secrets.md#example-rotate-a-secret) for a way to -remove a secret without disrupting running services. - -To update or roll back secrets more easily, consider adding a version -number or date to the secret name. This is made easier by the ability to control -the mount point of the secret within a given container. - -## Read more about `docker secret` commands - -Use these links to read about specific commands, or continue to the -[example about using secrets with a service](secrets.md#simple-example-get-started-with-secrets). - -- [`docker secret create`](../../reference/cli/docker/secret/create.md) -- [`docker secret inspect`](../../reference/cli/docker/secret/inspect.md) -- [`docker secret ls`](../../reference/cli/docker/secret/ls.md) -- [`docker secret rm`](../../reference/cli/docker/secret/rm.md) -- [`--secret`](../../reference/cli/docker/service/create.md#secret) flag for `docker service create` -- [`--secret-add` and `--secret-rm`](../../reference/cli/docker/service/update.md#secret-add) flags for `docker service update` - -## Examples - -This section includes three graduated examples which illustrate how to use -Docker secrets.

See [Windows support](#windows-support). - -### Defining and using secrets in compose files - -Both the `docker-compose` and `docker stack` commands support defining secrets -in a compose file. See -[the Compose file reference](../../compose/compose-file/legacy-versions.md) for details. - -### Simple example: Get started with secrets - -This simple example shows how secrets work in just a few commands. For a -real-world example, continue to -[Intermediate example: Use secrets with a Nginx service](#intermediate-example-use-secrets-with-a-nginx-service). - -1. Add a secret to Docker. The `docker secret create` command reads standard - input because the last argument, which represents the file to read the - secret from, is set to `-`. - - ```console - $ printf "This is a secret" | docker secret create my_secret_data - - ``` - -2. Create a `redis` service and grant it access to the secret. By default, - the container can access the secret at `/run/secrets/`, but - you can customize the file name on the container using the `target` option. - - ```console - $ docker service create --name redis --secret my_secret_data redis:alpine - ``` - -3. Verify that the task is running without issues using `docker service ps`. If - everything is working, the output looks similar to this: - - ```console - $ docker service ps redis - - ID NAME IMAGE NODE DESIRED STATE CURRENT STATE ERROR PORTS - bkna6bpn8r1a redis.1 redis:alpine ip-172-31-46-109 Running Running 8 seconds ago - ``` - - If there were an error, and the task were failing and repeatedly restarting, - you would see something like this: - - ```console - $ docker service ps redis - - NAME IMAGE NODE DESIRED STATE CURRENT STATE ERROR PORTS - redis.1.siftice35gla redis:alpine moby Running Running 4 seconds ago - \_ redis.1.whum5b7gu13e redis:alpine moby Shutdown Failed 20 seconds ago "task: non-zero exit (1)" - \_ redis.1.2s6yorvd9zow redis:alpine moby Shutdown Failed 56 seconds ago "task: non-zero exit (1)" - \_ redis.1.ulfzrcyaf6pg redis:alpine moby Shutdown Failed about a minute ago "task: non-zero exit (1)" - \_ redis.1.wrny5v4xyps6 redis:alpine moby Shutdown Failed 2 minutes ago "task: non-zero exit (1)" - ``` - -4. Get the ID of the `redis` service task container using `docker ps` , so that - you can use `docker container exec` to connect to the container and read the contents - of the secret data file, which defaults to being readable by all and has the - same name as the name of the secret. The first command below illustrates - how to find the container ID, and the second and third commands use shell - completion to do this automatically. - - ```console - $ docker ps --filter name=redis -q - - 5cb1c2348a59 - - $ docker container exec $(docker ps --filter name=redis -q) ls -l /run/secrets - - total 4 - -r--r--r-- 1 root root 17 Dec 13 22:48 my_secret_data - - $ docker container exec $(docker ps --filter name=redis -q) cat /run/secrets/my_secret_data - - This is a secret - ``` - -5. Verify that the secret is not available if you commit the container. - - ```console - $ docker commit $(docker ps --filter name=redis -q) committed_redis - - $ docker run --rm -it committed_redis cat /run/secrets/my_secret_data - - cat: can't open '/run/secrets/my_secret_data': No such file or directory - ``` - -6. Try removing the secret. The removal fails because the `redis` service is - running and has access to the secret. - - ```console - $ docker secret ls - - ID NAME CREATED UPDATED - wwwrxza8sxy025bas86593fqs my_secret_data 4 hours ago 4 hours ago - - - $ docker secret rm my_secret_data - - Error response from daemon: rpc error: code = 3 desc = secret - 'my_secret_data' is in use by the following service: redis - ``` - -7. Remove access to the secret from the running `redis` service by updating the - service. - - ```console - $ docker service update --secret-rm my_secret_data redis - ``` - -8. Repeat steps 3 and 4 again, verifying that the service no longer has access - to the secret. The container ID is different, because the - `service update` command redeploys the service. - - ```console - $ docker container exec -it $(docker ps --filter name=redis -q) cat /run/secrets/my_secret_data - - cat: can't open '/run/secrets/my_secret_data': No such file or directory - ``` - -9. Stop and remove the service, and remove the secret from Docker. - - ```console - $ docker service rm redis - - $ docker secret rm my_secret_data - ``` - -### Simple example: Use secrets in a Windows service - -This is a very simple example which shows how to use secrets with a Microsoft -IIS service running on Docker for Windows running Windows containers on -Microsoft Windows 10. It is a naive example that stores the webpage in a secret. - -This example assumes that you have PowerShell installed. - -1. Save the following into a new file `index.html`. - - ```html - - Hello Docker - -

Hello Docker! You have deployed a HTML page.

- - - ``` - -2. If you have not already done so, initialize or join the swarm. - - ```console - > docker swarm init - ``` - -3. Save the `index.html` file as a swarm secret named `homepage`. - - ```console - > docker secret create homepage index.html - ``` - -4. Create an IIS service and grant it access to the `homepage` secret. - - ```console - > docker service create ` - --name my-iis ` - --publish published=8000,target=8000 ` - --secret src=homepage,target="\inetpub\wwwroot\index.html" ` - microsoft/iis:nanoserver - ``` - - > **Note** - > - > There is technically no reason to use secrets for this - > example; [configs](configs.md) are a better fit. This example is - > for illustration only. - -5. Access the IIS service at `http://localhost:8000/`. It should serve - the HTML content from the first step. - -6. Remove the service and the secret. - - ```console - > docker service rm my-iis - > docker secret rm homepage - > docker image remove secret-test - ``` - -### Intermediate example: Use secrets with a Nginx service - -This example is divided into two parts. -[The first part](#generate-the-site-certificate) is all about generating -the site certificate and does not directly involve Docker secrets at all, but -it sets up [the second part](#configure-the-nginx-container), where you store -and use the site certificate and Nginx configuration as secrets. - -#### Generate the site certificate - -Generate a root CA and TLS certificate and key for your site. For production -sites, you may want to use a service such as `Let’s Encrypt` to generate the -TLS certificate and key, but this example uses command-line tools. This step -is a little complicated, but is only a set-up step so that you have -something to store as a Docker secret. If you want to skip these sub-steps, -you can [use Let's Encrypt](https://letsencrypt.org/getting-started/) to -generate the site key and certificate, name the files `site.key` and -`site.crt`, and skip to -[Configure the Nginx container](#configure-the-nginx-container). - -1. Generate a root key. - - ```console - $ openssl genrsa -out "root-ca.key" 4096 - ``` - -2. Generate a CSR using the root key. - - ```console - $ openssl req \ - -new -key "root-ca.key" \ - -out "root-ca.csr" -sha256 \ - -subj '/C=US/ST=CA/L=San Francisco/O=Docker/CN=Swarm Secret Example CA' - ``` - -3. Configure the root CA. Edit a new file called `root-ca.cnf` and paste - the following contents into it. This constrains the root CA to signing leaf - certificates and not intermediate CAs. - - ```ini - [root_ca] - basicConstraints = critical,CA:TRUE,pathlen:1 - keyUsage = critical, nonRepudiation, cRLSign, keyCertSign - subjectKeyIdentifier=hash - ``` - -4. Sign the certificate. - - ```console - $ openssl x509 -req -days 3650 -in "root-ca.csr" \ - -signkey "root-ca.key" -sha256 -out "root-ca.crt" \ - -extfile "root-ca.cnf" -extensions \ - root_ca - ``` - -5. Generate the site key. - - ```console - $ openssl genrsa -out "site.key" 4096 - ``` - -6. Generate the site certificate and sign it with the site key. - - ```console - $ openssl req -new -key "site.key" -out "site.csr" -sha256 \ - -subj '/C=US/ST=CA/L=San Francisco/O=Docker/CN=localhost' - ``` - -7. Configure the site certificate. Edit a new file called `site.cnf` and - paste the following contents into it. This constrains the site - certificate so that it can only be used to authenticate a server and - can't be used to sign certificates. - - ```ini - [server] - authorityKeyIdentifier=keyid,issuer - basicConstraints = critical,CA:FALSE - extendedKeyUsage=serverAuth - keyUsage = critical, digitalSignature, keyEncipherment - subjectAltName = DNS:localhost, IP:127.0.0.1 - subjectKeyIdentifier=hash - ``` - -8. Sign the site certificate. - - ```console - $ openssl x509 -req -days 750 -in "site.csr" -sha256 \ - -CA "root-ca.crt" -CAkey "root-ca.key" -CAcreateserial \ - -out "site.crt" -extfile "site.cnf" -extensions server - ``` - -9. The `site.csr` and `site.cnf` files are not needed by the Nginx service, but - you need them if you want to generate a new site certificate. Protect - the `root-ca.key` file. - -#### Configure the Nginx container - -1. Produce a very basic Nginx configuration that serves static files over HTTPS. - The TLS certificate and key are stored as Docker secrets so that they - can be rotated easily. - - In the current directory, create a new file called `site.conf` with the - following contents: - - ```nginx - server { - listen 443 ssl; - server_name localhost; - ssl_certificate /run/secrets/site.crt; - ssl_certificate_key /run/secrets/site.key; - - location / { - root /usr/share/nginx/html; - index index.html index.htm; - } - } - ``` - -2. Create three secrets, representing the key, the certificate, and the - `site.conf`. You can store any file as a secret as long as it is smaller - than 500 KB. This allows you to decouple the key, certificate, and - configuration from the services that use them. In each of these - commands, the last argument represents the path to the file to read the - secret from on the host machine's filesystem. In these examples, the secret - name and the file name are the same. - - ```console - $ docker secret create site.key site.key - - $ docker secret create site.crt site.crt - - $ docker secret create site.conf site.conf - ``` - - ```console - $ docker secret ls - - ID NAME CREATED UPDATED - 2hvoi9mnnaof7olr3z5g3g7fp site.key 58 seconds ago 58 seconds ago - aya1dh363719pkiuoldpter4b site.crt 24 seconds ago 24 seconds ago - zoa5df26f7vpcoz42qf2csth8 site.conf 11 seconds ago 11 seconds ago - ``` - -3. Create a service that runs Nginx and has access to the three secrets. The - last part of the `docker service create` command creates a symbolic link - from the location of the `site.conf` secret to `/etc/nginx.conf.d/`, where - Nginx looks for extra configuration files. This step happens before Nginx - actually starts, so you don't need to rebuild your image if you change the - Nginx configuration. - - > **Note** - > - > Normally you would create a Dockerfile which copies the `site.conf` - > into place, build the image, and run a container using your custom image. - > This example does not require a custom image. It puts the `site.conf` - > into place and runs the container all in one step. - - Secrets are located within the `/run/secrets/` directory in the container - by default, which may require extra steps in the container to make the - secret available in a different path. The example below creates a symbolic - link to the true location of the `site.conf` file so that Nginx can read it: - - ```console - $ docker service create \ - --name nginx \ - --secret site.key \ - --secret site.crt \ - --secret site.conf \ - --publish published=3000,target=443 \ - nginx:latest \ - sh -c "ln -s /run/secrets/site.conf /etc/nginx/conf.d/site.conf && exec nginx -g 'daemon off;'" - ``` - - Instead of creating symlinks, secrets allow you to specify a custom location - using the `target` option. The example below illustrates how the `site.conf` - secret is made available at `/etc/nginx/conf.d/site.conf` inside the container - without the use of symbolic links: - - ```console - $ docker service create \ - --name nginx \ - --secret site.key \ - --secret site.crt \ - --secret source=site.conf,target=/etc/nginx/conf.d/site.conf \ - --publish published=3000,target=443 \ - nginx:latest \ - sh -c "exec nginx -g 'daemon off;'" - ``` - - The `site.key` and `site.crt` secrets use the short-hand syntax, without a - custom `target` location set. The short syntax mounts the secrets in `/run/secrets/ - with the same name as the secret. Within the running containers, the following - three files now exist: - - - `/run/secrets/site.key` - - `/run/secrets/site.crt` - - `/etc/nginx/conf.d/site.conf` - -4. Verify that the Nginx service is running. - - ```console - $ docker service ls - - ID NAME MODE REPLICAS IMAGE - zeskcec62q24 nginx replicated 1/1 nginx:latest - - $ docker service ps nginx - - NAME IMAGE NODE DESIRED STATE CURRENT STATE ERROR PORTS - nginx.1.9ls3yo9ugcls nginx:latest moby Running Running 3 minutes ago - ``` - -5. Verify that the service is operational: you can reach the Nginx - server, and that the correct TLS certificate is being used. - - ```console - $ curl --cacert root-ca.crt https://localhost:3000 - - - - - Welcome to nginx! - - - -

To clean up after running this example, remove the `nginx` service and the - stored secrets. - - ```console - $ docker service rm nginx - - $ docker secret rm site.crt site.key site.conf - ``` - -### Advanced example: Use secrets with a WordPress service - -In this example, you create a single-node MySQL service with a custom root -password, add the credentials as secrets, and create a single-node WordPress -service which uses these credentials to connect to MySQL. The -[next example](#example-rotate-a-secret) builds on this one and shows you how to -rotate the MySQL password and update the services so that the WordPress service -can still connect to MySQL. - -This example illustrates some techniques to use Docker secrets to avoid saving -sensitive credentials within your image or passing them directly on the command -line. - -> **Note** -> -> This example uses a single-Engine swarm for simplicity, and uses a -> single-node MySQL service because a single MySQL server instance cannot be -> scaled by simply using a replicated service, and setting up a MySQL cluster is -> beyond the scope of this example. -> -> Also, changing a MySQL root passphrase isn’t as simple as changing -> a file on disk. You must use a query or a `mysqladmin` command to change the -> password in MySQL. - -1. Generate a random alphanumeric password for MySQL and store it as a Docker - secret with the name `mysql_password` using the `docker secret create` - command. To make the password shorter or longer, adjust the last argument of - the `openssl` command. This is just one way to create a relatively random - password. You can use another command to generate the password if you - choose. - - > **Note** - > - > After you create a secret, you cannot update it. You can only - > remove and re-create it, and you cannot remove a secret that a service is - > using. However, you can grant or revoke a running service's access to - > secrets using `docker service update`. If you need the ability to update a - > secret, consider adding a version component to the secret name, so that you - > can later add a new version, update the service to use it, then remove the - > old version. - - The last argument is set to `-`, which indicates that the input is read from - standard input. - - ```console - $ openssl rand -base64 20 | docker secret create mysql_password - - - l1vinzevzhj4goakjap5ya409 - ``` - - The value returned is not the password, but the ID of the secret. In the - remainder of this tutorial, the ID output is omitted. - - Generate a second secret for the MySQL `root` user. This secret isn't - shared with the WordPress service created later. It's only needed to - bootstrap the `mysql` service. - - ```console - $ openssl rand -base64 20 | docker secret create mysql_root_password - - ``` - - List the secrets managed by Docker using `docker secret ls`: - - ```console - $ docker secret ls - - ID NAME CREATED UPDATED - l1vinzevzhj4goakjap5ya409 mysql_password 41 seconds ago 41 seconds ago - yvsczlx9votfw3l0nz5rlidig mysql_root_password 12 seconds ago 12 seconds ago - ``` - - The secrets are stored in the encrypted Raft logs for the swarm. - -2. Create a user-defined overlay network which is used for communication - between the MySQL and WordPress services. There is no need to expose the - MySQL service to any external host or container. - - ```console - $ docker network create -d overlay mysql_private - ``` - -3. Create the MySQL service. The MySQL service has the following - characteristics: - - - Because the scale is set to `1`, only a single MySQL task runs. - Load-balancing MySQL is left as an exercise to the reader and involves - more than just scaling the service. - - Only reachable by other containers on the `mysql_private` network. - - Uses the volume `mydata` to store the MySQL data, so that it persists - across restarts to the `mysql` service. - - The secrets are each mounted in a `tmpfs` filesystem at - `/run/secrets/mysql_password` and `/run/secrets/mysql_root_password`. - They are never exposed as environment variables, nor can they be committed - to an image if the `docker commit` command is run. The `mysql_password` - secret is the one used by the non-privileged WordPress container to - connect to MySQL. - - Sets the environment variables `MYSQL_PASSWORD_FILE` and - `MYSQL_ROOT_PASSWORD_FILE` to point to the - files `/run/secrets/mysql_password` and `/run/secrets/mysql_root_password`. - The `mysql` image reads the password strings from those files when - initializing the system database for the first time. Afterward, the - passwords are stored in the MySQL system database itself. - - Sets environment variables `MYSQL_USER` and `MYSQL_DATABASE`. A new - database called `wordpress` is created when the container starts, and the - `wordpress` user has full permissions for this database only. This - user cannot create or drop databases or change the MySQL - configuration. - - ```console - $ docker service create \ - --name mysql \ - --replicas 1 \ - --network mysql_private \ - --mount type=volume,source=mydata,destination=/var/lib/mysql \ - --secret source=mysql_root_password,target=mysql_root_password \ - --secret source=mysql_password,target=mysql_password \ - -e MYSQL_ROOT_PASSWORD_FILE="/run/secrets/mysql_root_password" \ - -e MYSQL_PASSWORD_FILE="/run/secrets/mysql_password" \ - -e MYSQL_USER="wordpress" \ - -e MYSQL_DATABASE="wordpress" \ - mysql:latest - ``` - -4. Verify that the `mysql` container is running using the `docker service ls` command. - - ```console - $ docker service ls - - ID NAME MODE REPLICAS IMAGE - wvnh0siktqr3 mysql replicated 1/1 mysql:latest - ``` - -5. Now that MySQL is set up, create a WordPress service that connects to the - MySQL service. The WordPress service has the following characteristics: - - - Because the scale is set to `1`, only a single WordPress task runs. - Load-balancing WordPress is left as an exercise to the reader, because of - limitations with storing WordPress session data on the container - filesystem. - - Exposes WordPress on port 30000 of the host machine, so that you can access - it from external hosts. You can expose port 80 instead if you do not have - a web server running on port 80 of the host machine. - - Connects to the `mysql_private` network so it can communicate with the - `mysql` container, and also publishes port 80 to port 30000 on all swarm - nodes. - - Has access to the `mysql_password` secret, but specifies a different - target file name within the container. The WordPress container uses - the mount point `/run/secrets/wp_db_password`. - - Sets the environment variable `WORDPRESS_DB_PASSWORD_FILE` to the file - path where the secret is mounted. The WordPress service reads the - MySQL password string from that file and add it to the `wp-config.php` - configuration file. - - Connects to the MySQL container using the username `wordpress` and the - password in `/run/secrets/wp_db_password` and creates the `wordpress` - database if it does not yet exist. - - Stores its data, such as themes and plugins, in a volume called `wpdata` - so these files persist when the service restarts. - - ```console - $ docker service create \ - --name wordpress \ - --replicas 1 \ - --network mysql_private \ - --publish published=30000,target=80 \ - --mount type=volume,source=wpdata,destination=/var/www/html \ - --secret source=mysql_password,target=wp_db_password \ - -e WORDPRESS_DB_USER="wordpress" \ - -e WORDPRESS_DB_PASSWORD_FILE="/run/secrets/wp_db_password" \ - -e WORDPRESS_DB_HOST="mysql:3306" \ - -e WORDPRESS_DB_NAME="wordpress" \ - wordpress:latest - ``` - -6. Verify the service is running using `docker service ls` and - `docker service ps` commands. - - ```console - $ docker service ls - - ID NAME MODE REPLICAS IMAGE - wvnh0siktqr3 mysql replicated 1/1 mysql:latest - nzt5xzae4n62 wordpress replicated 1/1 wordpress:latest - ``` - - ```console - $ docker service ps wordpress - - ID NAME IMAGE NODE DESIRED STATE CURRENT STATE ERROR PORTS - aukx6hgs9gwc wordpress.1 wordpress:latest moby Running Running 52 seconds ago - ``` - - At this point, you could actually revoke the WordPress service's access to - the `mysql_password` secret, because WordPress has copied the secret to its - configuration file `wp-config.php`. Don't do that for now, because we - use it later to facilitate rotating the MySQL password. - -7. Access `http://localhost:30000/` from any swarm node and set up WordPress - using the web-based wizard. All of these settings are stored in the MySQL - `wordpress` database. WordPress automatically generates a password for your - WordPress user, which is completely different from the password WordPress - uses to access MySQL. Store this password securely, such as in a password - manager. You need it to log into WordPress after - [rotating the secret](#example-rotate-a-secret). - - Go ahead and write a blog post or two and install a WordPress plugin or - theme to verify that WordPress is fully operational and its state is saved - across service restarts. - -8. Do not clean up any services or secrets if you intend to proceed to the next - example, which demonstrates how to rotate the MySQL root password. - -### Example: Rotate a secret - -This example builds upon the previous one. In this scenario, you create a new -secret with a new MySQL password, update the `mysql` and `wordpress` services to -use it, then remove the old secret. - -> **Note** -> -> Changing the password on a MySQL database involves running extra -> queries or commands, as opposed to just changing a single environment variable -> or a file, since the image only sets the MySQL password if the database doesn’t -> already exist, and MySQL stores the password within a MySQL database by default. -> Rotating passwords or other secrets may involve additional steps outside of -> Docker. - -1. Create the new password and store it as a secret named `mysql_password_v2`. - - ```console - $ openssl rand -base64 20 | docker secret create mysql_password_v2 - - ``` - -2. Update the MySQL service to give it access to both the old and new secrets. - Remember that you cannot update or rename a secret, but you can revoke a - secret and grant access to it using a new target filename. - - ```console - $ docker service update \ - --secret-rm mysql_password mysql - - $ docker service update \ - --secret-add source=mysql_password,target=old_mysql_password \ - --secret-add source=mysql_password_v2,target=mysql_password \ - mysql - ``` - - Updating a service causes it to restart, and when the MySQL service restarts - the second time, it has access to the old secret under - `/run/secrets/old_mysql_password` and the new secret under - `/run/secrets/mysql_password`. - - Even though the MySQL service has access to both the old and new secrets - now, the MySQL password for the WordPress user has not yet been changed. - - > **Note** - > - > This example does not rotate the MySQL `root` password. - -3. Now, change the MySQL password for the `wordpress` user using the - `mysqladmin` CLI. This command reads the old and new password from the files - in `/run/secrets` but does not expose them on the command line or save them - in the shell history. - - Do this quickly and move on to the next step, because WordPress loses - the ability to connect to MySQL. - - First, find the ID of the `mysql` container task. - - ```console - $ docker ps --filter name=mysql -q - - c7705cf6176f - ``` - - Substitute the ID in the command below, or use the second variant which - uses shell expansion to do it all in a single step. - - ```console - $ docker container exec \ - bash -c 'mysqladmin --user=wordpress --password="$(< /run/secrets/old_mysql_password)" password "$(< /run/secrets/mysql_password)"' - ``` - - Or: - - ```console - $ docker container exec $(docker ps --filter name=mysql -q) \ - bash -c 'mysqladmin --user=wordpress --password="$(< /run/secrets/old_mysql_password)" password "$(< /run/secrets/mysql_password)"' - ``` - -4. Update the `wordpress` service to use the new password, keeping the target - path at `/run/secrets/wp_db_password`. This triggers a rolling restart of - the WordPress service and the new secret is used. - - ```console - $ docker service update \ - --secret-rm mysql_password \ - --secret-add source=mysql_password_v2,target=wp_db_password \ - wordpress - ``` - -5. Verify that WordPress works by browsing to http://localhost:30000/ on any - swarm node again. Use the WordPress username and password - from when you ran through the WordPress wizard in the previous task. - - Verify that the blog post you wrote still exists, and if you changed any - configuration values, verify that they are still changed. - -6. Revoke access to the old secret from the MySQL service and - remove the old secret from Docker. - - ```console - $ docker service update \ - --secret-rm mysql_password \ - mysql - - $ docker secret rm mysql_password - ``` - - -7. Run the following commands to remove the WordPress service, the MySQL container, - the `mydata` and `wpdata` volumes, and the Docker secrets: - - ```console - $ docker service rm wordpress mysql - - $ docker volume rm mydata wpdata - - $ docker secret rm mysql_password_v2 mysql_root_password - ``` - -## Build support for Docker Secrets into your images - -If you develop a container that can be deployed as a service and requires -sensitive data, such as a credential, as an environment variable, consider -adapting your image to take advantage of Docker secrets. One way to do this is -to ensure that each parameter you pass to the image when creating the container -can also be read from a file. - -Many of the Docker Official Images in the -[Docker library](https://github.com/docker-library/), such as the -[wordpress](https://github.com/docker-library/wordpress/) -image used in the above examples, have been updated in this way. - -When you start a WordPress container, you provide it with the parameters it -needs by setting them as environment variables. The WordPress image has been -updated so that the environment variables which contain important data for -WordPress, such as `WORDPRESS_DB_PASSWORD`, also have variants which can read -their values from a file (`WORDPRESS_DB_PASSWORD_FILE`). This strategy ensures -that backward compatibility is preserved, while allowing your container to read -the information from a Docker-managed secret instead of being passed directly. - -> **Note** -> -> Docker secrets do not set environment variables directly. This was a -> conscious decision, because environment variables can unintentionally be leaked -> between containers (for instance, if you use `--link`). - -## Use Secrets in Compose - -```yaml - -services: - db: - image: mysql:latest - volumes: - - db_data:/var/lib/mysql - environment: - MYSQL_ROOT_PASSWORD_FILE: /run/secrets/db_root_password - MYSQL_DATABASE: wordpress - MYSQL_USER: wordpress - MYSQL_PASSWORD_FILE: /run/secrets/db_password - secrets: - - db_root_password - - db_password - - wordpress: - depends_on: - - db - image: wordpress:latest - ports: - - "8000:80" - environment: - WORDPRESS_DB_HOST: db:3306 - WORDPRESS_DB_USER: wordpress - WORDPRESS_DB_PASSWORD_FILE: /run/secrets/db_password - secrets: - - db_password - - -secrets: - db_password: - file: db_password.txt - db_root_password: - file: db_root_password.txt - -volumes: - db_data: -``` - -This example creates a simple WordPress site using two secrets in -a Compose file. - -The top-level element `secrets` defines two secrets `db_password` and -`db_root_password`. - -When deploying, Docker creates these two secrets and populates them with the -content from the file specified in the Compose file. - -The `db` service uses both secrets, and `wordpress` is using one. - -When you deploy, Docker mounts a file under `/run/secrets/` in the -services.

With this information, the -nodes are able to log into the registry and pull the image. - -### Provide credential specs for managed service accounts - - In Enterprise Edition 3.0, security is improved through the centralized distribution and management of Group Managed Service Account(gMSA) credentials using Docker config functionality. Swarm now allows using a Docker config as a gMSA credential spec, which reduces the burden of distributing credential specs to the nodes on which they are used. - -> **Note** -> -> This option is only applicable to services using Windows containers. - - Credential spec files are applied at runtime, eliminating the need for host-based credential spec files or registry entries - no gMSA credentials are written to disk on worker nodes. You can make credential specs available to Docker Engine running swarm kit worker nodes before a container starts. When deploying a service using a gMSA-based config, the credential spec is passed directly to the runtime of containers in that service. - - The `--credential-spec` must be in one of the following formats: - - - `file://`: The referenced file must be present in the `CredentialSpecs` subdirectory in the docker data directory, which defaults to `C:\ProgramData\Docker\` on Windows. For example, specifying `file://spec.json` loads `C:\ProgramData\Docker\CredentialSpecs\spec.json`. -- `registry://`: The credential spec is read from the Windows registry on the daemon’s host. -- `config://`: The config name is automatically converted to the config ID in the CLI. -The credential spec contained in the specified `config` is used. - - The following simple example retrieves the gMSA name and JSON contents from your Active Directory (AD) instance: - - ```console -$ name="mygmsa" -$ contents="{...}" -$ echo $contents > contents.json -``` - -Make sure that the nodes to which you are deploying are correctly configured for the gMSA. - - To use a config as a credential spec, create a Docker config in a credential spec file named `credpspec.json`. - You can specify any name for the name of the `config`. - -```console -$ docker config create --label com.docker.gmsa.name=mygmsa credspec credspec.json -``` - -Now you can create a service using this credential spec. Specify the `--credential-spec` flag with the config name: - -```console -$ docker service create --credential-spec="config://credspec" -``` - - Your service uses the gMSA credential spec when it starts, but unlike a typical Docker config (used by passing the --config flag), the credential spec is not mounted into the container. - -## Update a service - -You can change almost everything about an existing service using the -`docker service update` command.

The following command removes the `my_web` service. - -```console -$ docker service remove my_web -``` - -## Service configuration details - -The following sections provide details about service configuration. This topic -does not cover every flag or scenario. In almost every instance where you can -define a configuration at service creation, you can also update an existing -service's configuration in a similar way. - -See the command-line references for -[`docker service create`](../../reference/cli/docker/service/create.md) and -[`docker service update`](../../reference/cli/docker/service/update.md), or run -one of those commands with the `--help` flag. - -### Configure the runtime environment - -You can configure the following options for the runtime environment in the -container: - -* Environment variables using the `--env` flag -* The working directory inside the container using the `--workdir` flag -* The username or UID using the `--user` flag - -The following service's containers have an environment variable `$MYVAR` -set to `myvalue`, run from the `/tmp/` directory, and run as the -`my_user` user. - -```console -$ docker service create --name helloworld \ - --env MYVAR=myvalue \ - --workdir /tmp \ - --user my_user \ - alpine ping docker.com -``` - -### Update the command an existing service runs - -To update the command an existing service runs, you can use the `--args` flag. -The following example updates an existing service called `helloworld` so that -it runs the command `ping docker.com` instead of whatever command it was running -before: - -```console -$ docker service update --args "ping docker.com" helloworld -``` - -### Specify the image version a service should use - -When you create a service without specifying any details about the version of -the image to use, the service uses the version tagged with the `latest` tag. -You can force the service to use a specific version of the image in a few -different ways, depending on your desired outcome. - -An image version can be expressed in several different ways: - -- If you specify a tag, the manager (or the Docker client, if you use - [content trust](../security/trust/index.md)) resolves that tag to a digest. - When the request to create a container task is received on a worker node, the - worker node only sees the digest, not the tag. - - ```console - $ docker service create --name="myservice" ubuntu:16.04 - ``` - - Some tags represent discrete releases, such as `ubuntu:16.04`. Tags like this - almost always resolve to a stable digest over time. It is recommended - that you use this kind of tag when possible. - - Other types of tags, such as `latest` or `nightly`, may resolve to a new - digest often, depending on how often an image's author updates the tag. It is - not recommended to run services using a tag which is updated frequently, to - prevent different service replica tasks from using different image versions. - -- If you don't specify a version at all, by convention the image's `latest` tag - is resolved to a digest. Workers use the image at this digest when creating - the service task. - - Thus, the following two commands are equivalent: - - ```console - $ docker service create --name="myservice" ubuntu - - $ docker service create --name="myservice" ubuntu:latest - ``` - -- If you specify a digest directly, that exact version of the image is always - used when creating service tasks. - - ```console - $ docker service create \ - --name="myservice" \ - ubuntu:16.04@sha256:35bc48a1ca97c3971611dc4662d08d131869daa692acb281c7e9e052924e38b1 - ``` - -When you create a service, the image's tag is resolved to the specific digest -the tag points to **at the time of service creation**. Worker nodes for that -service use that specific digest forever unless the service is explicitly -updated. This feature is particularly important if you do use often-changing tags -such as `latest`, because it ensures that all service tasks use the same version -of the image. - -> **Note**> -> -> If [content trust](../security/trust/index.md) is -> enabled, the client actually resolves the image's tag to a digest before -> contacting the swarm manager, to verify that the image is signed. -> Thus, if you use content trust, the swarm manager receives the request -> pre-resolved. In this case, if the client cannot resolve the image to a -> digest, the request fails. - -If the manager can't resolve the tag to a digest, each worker -node is responsible for resolving the tag to a digest, and different nodes may -use different versions of the image. If this happens, a warning like the -following is logged, substituting the placeholders for real information. - -```none -unable to pin image to digest: -``` - -To see an image's current digest, issue the command -`docker inspect :` and look for the `RepoDigests` line.

Other update -operations such as scaling the service, adding or removing networks or volumes, -renaming the service, or any other type of update operation do not update the -service's image. - -### Update a service's image after creation - -Each tag represents a digest, similar to a Git hash. Some tags, such as -`latest`, are updated often to point to a new digest. Others, such as -`ubuntu:16.04`, represent a released software version and are not expected to -update to point to a new digest often if at all. When you create a service, it -is constrained to create tasks using a specific digest of an image until you -update the service using `service update` with the `--image` flag. - -When you run `service update` with the `--image` flag, the swarm manager queries -Docker Hub or your private Docker registry for the digest the tag currently -points to and updates the service tasks to use that digest. - -> **Note** -> -> If you use [content trust](../security/trust/index.md), the Docker -> client resolves image and the swarm manager receives the image and digest, -> rather than a tag. - -Usually, the manager can resolve the tag to a new digest and the service -updates, redeploying each task to use the new image. If the manager can't -resolve the tag or some other problem occurs, the next two sections outline what -to expect. - -#### If the manager resolves the tag - -If the swarm manager can resolve the image tag to a digest, it instructs the -worker nodes to redeploy the tasks and use the image at that digest. - -- If a worker has cached the image at that digest, it uses it. - -- If not, it attempts to pull the image from Docker Hub or the private registry. - - - If it succeeds, the task is deployed using the new image. - - - If the worker fails to pull the image, the service fails to deploy on that - worker node. Docker tries again to deploy the task, possibly on a different - worker node. - -#### If the manager cannot resolve the tag - -If the swarm manager cannot resolve the image to a digest, all is not lost: - -- The manager instructs the worker nodes to redeploy the tasks using the image - at that tag. - -- If the worker has a locally cached image that resolves to that tag, it uses - that image. - -- If the worker does not have a locally cached image that resolves to the tag, - the worker tries to connect to Docker Hub or the private registry to pull the - image at that tag. - - - If this succeeds, the worker uses that image. - - - If this fails, the task fails to deploy and the manager tries again to deploy - the task, possibly on a different worker node. - -### Publish ports - -When you create a swarm service, you can publish that service's ports to hosts -outside the swarm in two ways: - -- [You can rely on the routing mesh](#publish-a-services-ports-using-the-routing-mesh). - When you publish a service port, the swarm makes the service accessible at the - target port on every node, regardless of whether there is a task for the - service running on that node or not. This is less complex and is the right - choice for many types of services. - -- [You can publish a service task's port directly on the swarm node](#publish-a-services-ports-directly-on-the-swarm-node) - where that service is running. This bypasses the routing mesh and provides the - maximum flexibility, including the ability for you to develop your own routing - framework. However, you are responsible for keeping track of where each task is - running and routing requests to the tasks, and load-balancing across the nodes. - -Keep reading for more information and use cases for each of these methods. - -#### Publish a service's ports using the routing mesh - -To publish a service's ports externally to the swarm, use the -`--publish :` flag. The swarm makes the service -accessible at the published port on every swarm node. If an external host -connects to that port on any swarm node, the routing mesh routes it to a task. -The external host does not need to know the IP addresses or internally-used -ports of the service tasks to interact with the service. When a user or process -connects to a service, any worker node running a service task may respond. For -more details about swarm service networking, see -[Manage swarm service networks](networking.md). - -##### Example: Run a three-task Nginx service on 10-node swarm - -Imagine that you have a 10-node swarm, and you deploy an Nginx service running -three tasks on a 10-node swarm: - -```console -$ docker service create --name my_web \ - --replicas 3 \ - --publish published=8080,target=80 \ - nginx -``` - -Three tasks run on up to three nodes. You don't need to know which nodes -are running the tasks; connecting to port 8080 on any of the 10 nodes -connects you to one of the three `nginx` tasks. You can test this using `curl`. -The following example assumes that `localhost` is one of the swarm nodes. If -this is not the case, or `localhost` does not resolve to an IP address on your -host, substitute the host's IP address or resolvable host name. - -The HTML output is truncated: - -```console -$ curl localhost:8080 - - - - -Welcome to nginx! -...truncated... - -``` - -Subsequent connections may be routed to the same swarm node or a different one. - -#### Publish a service's ports directly on the swarm node - -Using the routing mesh may not be the right choice for your application if you -need to make routing decisions based on application state or you need total -control of the process for routing requests to your service's tasks. To publish -a service's port directly on the node where it is running, use the `mode=host` -option to the `--publish` flag. - -> **Note** -> -> If you publish a service's ports directly on the swarm node using -> `mode=host` and also set `published=` this creates an implicit -> limitation that you can only run one task for that service on a given swarm -> node. You can work around this by specifying `published` without a port -> definition, which causes Docker to assign a random port for each task. -> -> In addition, if you use `mode=host` and you do not use the -> `--mode=global` flag on `docker service create`, it is difficult to know -> which nodes are running the service to route work to them. - -##### Example: Run an `nginx` web server service on every swarm node - -[nginx](https://hub.docker.com/_/nginx/) is an open source reverse proxy, load -balancer, HTTP cache, and a web server. If you run nginx as a service using the -routing mesh, connecting to the nginx port on any swarm node shows you the -web page for (effectively) a random swarm node running the service. - -The following example runs nginx as a service on each node in your swarm and -exposes nginx port locally on each swarm node. - -```console -$ docker service create \ - --mode global \ - --publish mode=host,target=80,published=8080 \ - --name=nginx \ - nginx:latest -``` - -You can reach the nginx server on port 8080 of every swarm node. If you add a -node to the swarm, a nginx task is started on it. You cannot start another -service or container on any swarm node which binds to port 8080. - -> **Note** -> -> This is a purely illustrative example. Creating an application-layer -> routing framework for a multi-tiered service is complex and out of scope for -> this topic. - -### Connect the service to an overlay network - -You can use overlay networks to connect one or more services within the swarm. - -First, create overlay network on a manager node using the `docker network create` -command with the `--driver overlay` flag. - -```console -$ docker network create --driver overlay my-network -``` - -After you create an overlay network in swarm mode, all manager nodes have access -to the network. - -You can create a new service and pass the `--network` flag to attach the service -to the overlay network: - -```console -$ docker service create \ - --replicas 3 \ - --network my-network \ - --name my-web \ - nginx -``` - -The swarm extends `my-network` to each node running the service. - -You can also connect an existing service to an overlay network using the -`--network-add` flag. - -```console -$ docker service update --network-add my-network my-web -``` - -To disconnect a running service from a network, use the `--network-rm` flag. - -```console -$ docker service update --network-rm my-network my-web -``` - -For more information on overlay networking and service discovery, refer to -[Attach services to an overlay network](networking.md) and -[Docker swarm mode overlay network security model](../../network/drivers/overlay.md). - -### Grant a service access to secrets - -To create a service with access to Docker-managed secrets, use the `--secret` -flag. For more information, see -[Manage sensitive strings (secrets) for Docker services](secrets.md) - -### Customize a service's isolation mode - -> **Important** -> -> This setting applies to Windows hosts only and is ignored for Linux hosts. -{ .important } - -Docker allows you to specify a swarm service's isolation -mode. The isolation mode can be one of the following: - -- `default`: Use the default isolation mode configured for the Docker host, as - configured by the `-exec-opt` flag or `exec-opts` array in `daemon.json`. If - the daemon does not specify an isolation technology, `process` is the default - for Windows Server, and `hyperv` is the default (and only) choice for - Windows 10. - -- `process`: Run the service tasks as a separate process on the host. - - > **Note** - > - > `process` isolation mode is only supported on Windows Server. - > Windows 10 only supports `hyperv` isolation mode. - -- `hyperv`: Run the service tasks as isolated `hyperv` tasks. This increases - overhead but provides more isolation. - -You can specify the isolation mode when creating or updating a new service using -the `--isolation` flag. - -### Control service placement - -Swarm services provide a few different ways for you to control scale and -placement of services on different nodes. - -- You can specify whether the service needs to run a specific number of replicas - or should run globally on every worker node. See - [Replicated or global services](#replicated-or-global-services). - -- You can configure the service's - [CPU or memory requirements](#reserve-memory-or-cpus-for-a-service), and the - service only runs on nodes which can meet those requirements. - -- [Placement constraints](#placement-constraints) let you configure the service - to run only on nodes with specific (arbitrary) metadata set, and cause the - deployment to fail if appropriate nodes do not exist. For instance, you can - specify that your service should only run on nodes where an arbitrary label - `pci_compliant` is set to `true`. - -- [Placement preferences](#placement-preferences) let you apply an arbitrary - label with a range of values to each node, and spread your service's tasks - across those nodes using an algorithm. Currently, the only supported algorithm - is `spread`, which tries to place them evenly. For instance, if you - label each node with a label `rack` which has a value from 1-10, then specify - a placement preference keyed on `rack`, then service tasks are placed as - evenly as possible across all nodes with the label `rack`, after taking other - placement constraints, placement preferences, and other node-specific - limitations into account. - - Unlike constraints, placement preferences are best-effort, and a service does - not fail to deploy if no nodes can satisfy the preference. If you specify a - placement preference for a service, nodes that match that preference are - ranked higher when the swarm managers decide which nodes should run the - service tasks. Other factors, such as high availability of the service, - also factor into which nodes are scheduled to run service tasks. For - example, if you have N nodes with the rack label (and then some others), and - your service is configured to run N+1 replicas, the +1 is scheduled on a - node that doesn't already have the service on it if there is one, regardless - of whether that node has the `rack` label or not. - - -#### Replicated or global services - -Swarm mode has two types of services: replicated and global. For replicated -services, you specify the number of replica tasks for the swarm manager to -schedule onto available nodes. For global services, the scheduler places one -task on each available node that meets the service's -[placement constraints](#placement-constraints) and -[resource requirements](#reserve-memory-or-cpus-for-a-service). - -You control the type of service using the `--mode` flag. If you don't specify a -mode, the service defaults to `replicated`. For replicated services, you specify -the number of replica tasks you want to start using the `--replicas` flag. For -example, to start a replicated nginx service with 3 replica tasks: - -```console -$ docker service create \ - --name my_web \ - --replicas 3 \ - nginx -``` - -To start a global service on each available node, pass `--mode global` to -`docker service create`. Every time a new node becomes available, the scheduler -places a task for the global service on the new node. For example to start a -service that runs alpine on every node in the swarm: - -```console -$ docker service create \ - --name myservice \ - --mode global \ - alpine top -``` - -Service constraints let you set criteria for a node to meet before the scheduler -deploys a service to the node. You can apply constraints to the -service based upon node attributes and metadata or engine metadata. For more -information on constraints, refer to the `docker service create` -[CLI reference](../../reference/cli/docker/service/create.md). - -#### Reserve memory or CPUs for a service - -To reserve a given amount of memory or number of CPUs for a service, use the -`--reserve-memory` or `--reserve-cpu` flags. If no available nodes can satisfy -the requirement (for instance, if you request 4 CPUs and no node in the swarm -has 4 CPUs), the service remains in a pending state until an appropriate node is -available to run its tasks. - -##### Out Of Memory Exceptions (OOME) - -If your service attempts to use more memory than the swarm node has available, -you may experience an Out Of Memory Exception (OOME) and a container, or the -Docker daemon, might be killed by the kernel OOM killer. To prevent this from -happening, ensure that your application runs on hosts with adequate memory and -see -[Understand the risks of running out of memory](../../config/containers/resource_constraints.md#understand-the-risks-of-running-out-of-memory). - -Swarm services allow you to use resource constraints, placement preferences, and -labels to ensure that your service is deployed to the appropriate swarm nodes. - -#### Placement constraints - -Use placement constraints to control the nodes a service can be assigned to. In -the following example, the service only runs on nodes with the -[label](manage-nodes.md#add-or-remove-label-metadata) `region` set -to `east`. If no appropriately-labelled nodes are available, tasks will wait in -`Pending` until they become available. The `--constraint` flag uses an equality -operator (`==` or `!=`). For replicated services, it is possible that all -services run on the same node, or each node only runs one replica, or that some -nodes don't run any replicas. For global services, the service runs on every -node that meets the placement constraint and any [resource requirements](#reserve-memory-or-cpus-for-a-service). - -```console -$ docker service create \ - --name my-nginx \ - --replicas 5 \ - --constraint node.labels.region==east \ - nginx -``` - -You can also use the `constraint` service-level key in a `compose.yml` -file. - -If you specify multiple placement constraints, the service only deploys onto -nodes where they are all met. The following example limits the service to run on -all nodes where `region` is set to `east` and `type` is not set to `devel`: - -```console -$ docker service create \ - --name my-nginx \ - --mode global \ - --constraint node.labels.region==east \ - --constraint node.labels.type!=devel \ - nginx -``` - -You can also use placement constraints in conjunction with placement preferences -and CPU/memory constraints. Be careful not to use settings that are not -possible to fulfill. - -For more information on constraints, refer to the `docker service create` -[CLI reference](../../reference/cli/docker/service/create.md). - -#### Placement preferences - -While [placement constraints](#placement-constraints) limit the nodes a service -can run on, _placement preferences_ try to place tasks on appropriate nodes -in an algorithmic way (currently, only spread evenly). For instance, if you -assign each node a `rack` label, you can set a placement preference to spread -the service evenly across nodes with the `rack` label, by value. This way, if -you lose a rack, the service is still running on nodes on other racks. - -Placement preferences are not strictly enforced. If no node has the label -you specify in your preference, the service is deployed as though the -preference were not set. - -> **Note** -> -> Placement preferences are ignored for global services. - -The following example sets a preference to spread the deployment across nodes -based on the value of the `datacenter` label. If some nodes have -`datacenter=us-east` and others have `datacenter=us-west`, the service is -deployed as evenly as possible across the two sets of nodes. - -```console -$ docker service create \ - --replicas 9 \ - --name redis_2 \ - --placement-pref 'spread=node.labels.datacenter' \ - redis:3.0.6 -``` - -> **Note** -> -> Nodes which are missing the label used to spread still receive -> task assignments. As a group, these nodes receive tasks in equal -> proportion to any of the other groups identified by a specific label -> value. In a sense, a missing label is the same as having the label with -> a null value attached to it. If the service should only run on -> nodes with the label being used for the spread preference, the -> preference should be combined with a constraint. - -You can specify multiple placement preferences, and they are processed in the -order they are encountered. The following example sets up a service with -multiple placement preferences. Tasks are spread first over the various -datacenters, and then over racks (as indicated by the respective labels): - -```console -$ docker service create \ - --replicas 9 \ - --name redis_2 \ - --placement-pref 'spread=node.labels.datacenter' \ - --placement-pref 'spread=node.labels.rack' \ - redis:3.0.6 -``` - -You can also use placement preferences in conjunction with placement constraints -or CPU/memory constraints. Be careful not to use settings that are not -possible to fulfill. - -This diagram illustrates how placement preferences work: - -![How placement preferences work](images/placement_prefs.png) - -When updating a service with `docker service update`, `--placement-pref-add` -appends a new placement preference after all existing placement preferences. -`--placement-pref-rm` removes an existing placement preference that matches the -argument. - - -### Configure a service's update behavior - -When you create a service, you can specify a rolling update behavior for how the -swarm should apply changes to the service when you run `docker service update`. -You can also specify these flags as part of the update, as arguments to -`docker service update`. - -The `--update-delay` flag configures the time delay between updates to a service -task or sets of tasks. You can describe the time `T` as a combination of the -number of seconds `Ts`, minutes `Tm`, or hours `Th`. So `10m30s` indicates a 10 -minute 30 second delay. - -By default the scheduler updates 1 task at a time. You can pass the -`--update-parallelism` flag to configure the maximum number of service tasks -that the scheduler updates simultaneously. - -When an update to an individual task returns a state of `RUNNING`, the scheduler -continues the update by continuing to another task until all tasks are updated. -If at any time during an update a task returns `FAILED`, the scheduler pauses -the update. You can control the behavior using the `--update-failure-action` -flag for `docker service create` or `docker service update`. - -In the example service below, the scheduler applies updates to a maximum of 2 -replicas at a time. When an updated task returns either `RUNNING` or `FAILED`, -the scheduler waits 10 seconds before stopping the next task to update: - -```console -$ docker service create \ - --replicas 10 \ - --name my_web \ - --update-delay 10s \ - --update-parallelism 2 \ - --update-failure-action continue \ - alpine -``` - -The `--update-max-failure-ratio` flag controls what fraction of tasks can fail -during an update before the update as a whole is considered to have failed. For -example, with `--update-max-failure-ratio 0.1 --update-failure-action pause`, -after 10% of the tasks being updated fail, the update is paused. - -An individual task update is considered to have failed if the task doesn't -start up, or if it stops running within the monitoring period specified with -the `--update-monitor` flag. The default value for `--update-monitor` is 30 -seconds, which means that a task failing in the first 30 seconds after it's -started counts towards the service update failure threshold, and a failure -after that is not counted. - -### Roll back to the previous version of a service - -In case the updated version of a service doesn't function as expected, it's -possible to manually roll back to the previous version of the service using -`docker service update`'s `--rollback` flag. This reverts the service -to the configuration that was in place before the most recent -`docker service update` command. - -Other options can be combined with `--rollback`; for example, -`--update-delay 0s`, to execute the rollback without a delay between tasks: - -```console -$ docker service update \ - --rollback \ - --update-delay 0s - my_web -``` - -You can configure a service to roll back automatically if a service update fails -to deploy. See [Automatically roll back if an update fails](#automatically-roll-back-if-an-update-fails). - -Manual rollback is handled at the server side, which allows manually-initiated -rollbacks to respect the new rollback parameters. Note that `--rollback` cannot -be used in conjunction with other flags to `docker service update`. - -### Automatically roll back if an update fails - -You can configure a service in such a way that if an update to the service -causes redeployment to fail, the service can automatically roll back to the -previous configuration. This helps protect service availability. You can set -one or more of the following flags at service creation or update. If you do not -set a value, the default is used. - -| Flag | Default | Description | -|:-------------------------------|:--------|:------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| -| `--rollback-delay` | `0s` | Amount of time to wait after rolling back a task before rolling back the next one. A value of `0` means to roll back the second task immediately after the first rolled-back task deploys. | -| `--rollback-failure-action` | `pause` | When a task fails to roll back, whether to `pause` or `continue` trying to roll back other tasks. | -| `--rollback-max-failure-ratio` | `0` | The failure rate to tolerate during a rollback, specified as a floating-point number between 0 and 1. For instance, given 5 tasks, a failure ratio of `.2` would tolerate one task failing to roll back. A value of `0` means no failure are tolerated, while a value of `1` means any number of failure are tolerated. | -| `--rollback-monitor` | `5s` | Duration after each task rollback to monitor for failure. If a task stops before this time period has elapsed, the rollback is considered to have failed. | -| `--rollback-parallelism` | `1` | The maximum number of tasks to roll back in parallel. By default, one task is rolled back at a time. A value of `0` causes all tasks to be rolled back in parallel. | - -The following example configures a `redis` service to roll back automatically -if a `docker service update` fails to deploy. Two tasks can be rolled back in -parallel. Tasks are monitored for 20 seconds after rollback to be sure they do -not exit, and a maximum failure ratio of 20% is tolerated. Default values are -used for `--rollback-delay` and `--rollback-failure-action`. - -```console -$ docker service create --name=my_redis \ - --replicas=5 \ - --rollback-parallelism=2 \ - --rollback-monitor=20s \ - --rollback-max-failure-ratio=.2 \ - redis:latest -``` - -### Give a service access to volumes or bind mounts - -For best performance and portability, you should avoid writing important data -directly into a container's writable layer. You should instead use data volumes -or bind mounts. This principle also applies to services. - -You can create two types of mounts for services in a swarm, `volume` mounts or -`bind` mounts. Regardless of which type of mount you use, configure it using the -`--mount` flag when you create a service, or the `--mount-add` or `--mount-rm` -flag when updating an existing service. The default is a data volume if you -don't specify a type. - -#### Data volumes - -Data volumes are storage that exist independently of a container. The -lifecycle of data volumes under swarm services is similar to that under -containers. Volumes outlive tasks and services, so their removal must be -managed separately. Volumes can be created before deploying a service, or if -they don't exist on a particular host when a task is scheduled there, they are -created automatically according to the volume specification on the service. - -To use existing data volumes with a service use the `--mount` flag: - -```console -$ docker service create \ - --mount src=,dst= \ - --name myservice \ - -``` - -If a volume with the name `` doesn't exist when a task is -scheduled to a particular host, then one is created. The default volume -driver is `local`. To use a different volume driver with this create-on-demand -pattern, specify the driver and its options with the `--mount` flag: - -```console -$ docker service create \ - --mount type=volume,src=,dst=,volume-driver=,volume-opt==,volume-opt== - --name myservice \ - -``` - -For more information on how to create data volumes and the use of volume -drivers, see [Use volumes](../../storage/volumes.md). - - -#### Bind mounts - -Bind mounts are file system paths from the host where the scheduler deploys -the container for the task. Docker mounts the path into the container. The -file system path must exist before the swarm initializes the container for the -task. - -The following examples show bind mount syntax: - -- To mount a read-write bind: - - ```console - $ docker service create \ - --mount type=bind,src=,dst= \ - --name myservice \ - - ``` - -- To mount a read-only bind: - - ```console - $ docker service create \ - --mount type=bind,src=,dst=,readonly \ - --name myservice \ - - ``` - -> **Important** -> -> Bind mounts can be useful but they can also cause problems. In -> most cases, it is recommended that you architect your application such that -> mounting paths from the host is unnecessary. The main risks include the -> following: -> -> - If you bind mount a host path into your service’s containers, the path -> must exist on every swarm node. The Docker swarm mode scheduler can schedule -> containers on any machine that meets resource availability requirements -> and satisfies all constraints and placement preferences you specify. -> -> - The Docker swarm mode scheduler may reschedule your running service -> containers at any time if they become unhealthy or unreachable. -> -> - Host bind mounts are non-portable. When you use bind mounts, there is no -> guarantee that your application runs the same way in development as it does -> in production. -{ .important } - -### Create services using templates - -You can use templates for some flags of `service create`, using the syntax -provided by the Go's [text/template](https://golang.org/pkg/text/template/) -package. - -The following flags are supported: - -- `--hostname` -- `--mount` -- `--env` - -Valid placeholders for the Go template are: - -| Placeholder | Description | -|:------------------|:---------------| -| `.Service.ID` | Service ID | -| `.Service.Name` | Service name | -| `.Service.Labels` | Service labels | -| `.Node.ID` | Node ID | -| `.Node.Hostname` | Node hostname | -| `.Task.Name` | Task name | -| `.Task.Slot` | Task slot | - -#### Template example - -This example sets the template of the created containers based on the -service's name and the ID of the node where the container is running: - - -```console -$ docker service create --name hosttempl \ - --hostname="{{.Node.ID}}-{{.Service.Name}}"\ - busybox top -``` - - -To see the result of using the template, use the `docker service ps` and -`docker inspect` commands. - -```console -$ docker service ps va8ew30grofhjoychbr6iot8c - -ID NAME IMAGE NODE DESIRED STATE CURRENT STATE ERROR PORTS -wo41w8hg8qan hosttempl.1 busybox:latest@sha256:29f5d56d12684887bdfa50dcd29fc31eea4aaf4ad3bec43daf19026a7ce69912 2e7a8a9c4da2 Running Running about a minute ago -``` - - -```console -$ docker inspect --format="{{.Config.Hostname}}" hosttempl.1.wo41w8hg8qanxwjwsg4kxpprj -``` - - -## Learn More - -* [Swarm administration guide](admin_guide.md) -* [Docker Engine command line reference](../../reference/cli/docker/) -* [Swarm mode tutorial](swarm-tutorial/index.md) diff --git a/content/engine/swarm/swarm-tutorial/_index.md b/content/engine/swarm/swarm-tutorial/_index.md deleted file mode 100644 index 16d20add940d..000000000000 --- a/content/engine/swarm/swarm-tutorial/_index.md +++ /dev/null @@ -1,101 +0,0 @@ ---- -description: Getting Started tutorial for Docker Engine Swarm mode -keywords: tutorial, cluster management, swarm mode, docker engine, get started -title: Getting started with Swarm mode -toc_max: 4 ---- - -This tutorial introduces you to the features of Docker Engine Swarm mode.

A Dockerfile is simply a text-based file with no file extension that contains a script of instructions. Docker uses this script to build a container image. + +1. In the `getting-started-app` directory, the same location as the + `package.json` file, create a file named `Dockerfile` with the following contents: + + ```dockerfile + # syntax=docker/dockerfile:1 + + FROM node:24-alpine + WORKDIR /app + COPY . . + RUN npm install --omit=dev + CMD ["node", "src/index.js"] + EXPOSE 3000 + ``` + This Dockerfile does the following: + + - Uses `node:24-alpine` as the base image, a lightweight Linux image with Node.js pre-installed + - Sets `/app` as the working directory + - Copies source code into the image + - Installs the necessary dependencies + - Specifies the command to start the application + - Documents that the app listens on port 3000 + +2. Build the image using the following commands: + + In the terminal, make sure you're in the `getting-started-app` directory. Replace `/path/to/getting-started-app` with the path to your `getting-started-app` directory. + + ```console + $ cd /path/to/getting-started-app + ``` + + Build the image. + + ```console + $ docker build -t getting-started . + ``` + + The `docker build` command uses the Dockerfile to build a new image. You might have noticed that Docker downloaded a lot of "layers". This is because you instructed the builder that you wanted to start from the `node:24-alpine` image. But, since you didn't have that on your machine, Docker needed to download the image. + + After Docker downloaded the image, the instructions from the Dockerfile copied in your application and used `npm` to install your application's dependencies. + + Finally, the `-t` flag tags your image. Think of this as a human-readable name for the final image. Since you named the image `getting-started`, you can refer to that image when you run a container. + + The `.` at the end of the `docker build` command tells Docker that it should look for the `Dockerfile` in the current directory. + +## Start an app container + +Now that you have an image, you can run the application in a container using the `docker run` command. + +1. Run your container using the `docker run` command and specify the name of the image you just created: + + ```console + $ docker run -d -p 127.0.0.1:3000:3000 getting-started + ``` + + The `-d` flag (short for `--detach`) runs the container in the background. + This means that Docker starts your container and returns you to the terminal + prompt. Also, it does not display logs in the terminal. + + The `-p` flag (short for `--publish`) creates a port mapping between the + host and the container. The `-p` flag takes a string value in the format of + `HOST:CONTAINER`, where `HOST` is the address on the host, and `CONTAINER` + is the port on the container. The command publishes the container's port + 3000 to `127.0.0.1:3000` (`localhost:3000`) on the host. Without the port + mapping, you wouldn't be able to access the application from the host. + +2.

Then, you'll dig into the Compose file, Dockerfile, and app to see how it +all works together. + +## Prerequisites + +To follow this guide, you need to: + + - [Install Docker Desktop 4.43 or later](../get-started/get-docker.md) + - [Enable Docker Model Runner](/manuals/ai/model-runner.md#enable-dmr-in-docker-desktop) + - At least the following hardware specifications: + - VRAM: 3.5 GB + - Storage: 2.31 GB + +## Step 1: Clone the sample application + +You'll use an existing sample application that demonstrates how to connect a +model to an external tool using Docker's AI features. + +```console +$ git clone https://github.com/docker/compose-for-agents.git +$ cd compose-for-agents/adk/ +``` + +## Step 2: Run the application locally + +Your machine must meet the necessary hardware requirements to run the +entire application stack locally using Docker Compose. This lets you test the +application end-to-end, including the model and MCP gateway, without needing to +run in the cloud. This particular example uses the [Gemma 3 4B +model](https://hub.docker.com/r/ai/gemma3) with a context size of `10000`. + +Hardware requirements: + - VRAM: 3.5 GB + - Storage: 2.31 GB + +If your machine exceeds those requirements, consider running the application with a larger +context size or a larger model to improve the agents performance. You can easily +update model and context size in the `compose.yaml` file. + +To run the application locally, follow these steps: + +1. In the `adk/` directory of the cloned repository, run the following command in a + terminal to build and run the application: + + ```console + $ docker compose up + ``` + + The first time you run this command, Docker pulls the + model from Docker Hub, which may take some time. + +2. Visit [http://localhost:8080](http://localhost:8080). Enter a correct or + incorrect fact in the prompt and hit enter. An agent searches DuckDuckGo to + verify it and another agent revises the output. + + ![Screenshot of the application](./images/agentic-ai-app.png) + +3. Press ctrl-c in the terminal to stop the application when you're done. + +## Step 3: Review the application environment + +You can find the `compose.yaml` file in the `adk/` directory. Open it in a text +editor to see how the services are defined. + +```yaml {collapse=true,title=compose.yaml} +services: + adk: + build: + context: . + ports: + # expose port for web interface + - "8080:8080" + environment: + # point adk at the MCP gateway + - MCPGATEWAY_ENDPOINT=http://mcp-gateway:8811/sse + depends_on: + - mcp-gateway + models: + gemma3 : + endpoint_var: MODEL_RUNNER_URL + model_var: MODEL_RUNNER_MODEL + + mcp-gateway: + # mcp-gateway secures your MCP servers + image: docker/mcp-gateway:latest + use_api_socket: true + command: + - --transport=sse + # add any MCP servers you want to use + - --servers=duckduckgo + +models: + gemma3: + # pre-pull the model when starting Docker Model Runner + model: ai/gemma3:4B-Q4_0 + context_size: 10000 # 3.5 GB VRAM + # increase context size to handle search results + # context_size: 131000 # 7.6 GB VRAM +``` + +The app consists of three main components: + + - The `adk` service, which is the web application that runs the agentic AI + application. This service talks to the MCP gateway and model. + - The `mcp-gateway` service, which is the MCP gateway that connects the app + to external tools and services. + - The `models` block, which defines the model to use with the application. + +When you examine the `compose.yaml` file, you'll notice two notable elements for the model: + + - A service‑level `models` block in the `adk` service + - A top-level `models` block + +These two blocks together let Docker Compose automatically start and connect +your ADK web app to the specified LLM. + +> [!TIP] +> +> Looking for more models to use? Check out the [Docker AI Model +> Catalog](https://hub.docker.com/catalogs/models/). + +When examining the `compose.yaml` file, you'll notice the gateway service is a +Docker-maintained image, +[`docker/mcp-gateway:latest`](https://hub.docker.com/r/docker/agents_gateway). +This image is Docker's open source [MCP +Gateway](https://github.com/docker/docker-mcp/) that enables your application to +connect to MCP servers, which expose tools that models can call. In this +example, it uses the [`duckduckgo` MCP +server](https://hub.docker.com/mcp/server/duckduckgo/overview) to perform web +searches. + +> [!TIP] +> +> Looking for more MCP servers to use? Check out the [Docker MCP +> Catalog](https://hub.docker.com/catalogs/mcp/). + +With only a few lines of instructions in a Compose file, you're able to run and +connect all the necessary services of an agentic AI application. + +In addition to the Compose file, the Dockerfile and the +`entrypoint.sh` script it creates, play a role in wiring up the AI stack at build and +runtime. You can find the `Dockerfile` in the `adk/` directory. Open it in a +text editor. + +```dockerfile {collapse=true,title=Dockerfile} +# Use Python 3.11 slim image as base +FROM python:3.13-slim +ENV PYTHONUNBUFFERED=1 + +RUN pip install uv + +WORKDIR /app +# Install system dependencies +COPY pyproject.toml uv.lock ./ +RUN --mount=type=cache,target=/root/.cache/uv \ + UV_COMPILE_BYTECODE=1 UV_LINK_MODE=copy \ + uv pip install --system . +# Copy application code +COPY agents/ ./agents/ +RUN python -m compileall -q . + +COPY < +> **Acknowledgment** +> +> Docker extends its sincere gratitude to [Kristiyan Velkov](https://www.linkedin.com/in/kristiyan-velkov-763130b3/) for authoring this guide.

You can +also use Bake to run your tests, effectively using BuildKit as a task runner. +Running your tests in containers is great for ensuring reproducible results. +This section shows how to add two types of tests: + +- Unit testing with `go test`. +- Linting for style violations with `golangci-lint`. + +In Test-Driven Development (TDD) fashion, start by adding a new `test` target +to the Bake file: + +```hcl +target "test" { + target = "test" + output = ["type=cacheonly"] +} +``` + +> [!TIP] +> Using `type=cacheonly` ensures that the build output is effectively +> discarded; the layers are saved to BuildKit's cache, but Buildx will not +> attempt to load the result to the Docker Engine's image store. +> +> For test runs, you don't need to export the build output — only the test +> execution matters. + +To execute this Bake target, run `docker buildx bake test`. At this time, +you'll receive an error indicating that the `test` stage does not exist in the +Dockerfile. + +```console +$ docker buildx bake test +[+] Building 1.2s (6/6) FINISHED + => [internal] load local bake definitions +... +ERROR: failed to solve: target stage "test" could not be found +``` + +To satisfy this target, add the corresponding Dockerfile target. The `test` +stage here is based on the same base stage as the build stage. + +```dockerfile +FROM base AS test +RUN --mount=target=. \ + --mount=type=cache,target=/go/pkg/mod \ + go test . +``` + +> [!TIP] +> The [`--mount=type=cache` directive](/manuals/build/cache/optimize.md#use-cache-mounts) +> caches Go modules between builds, improving build performance by avoiding the +> need to re-download dependencies. This shared cache ensures that the same +> dependency set is available across build, test, and other stages. + +Now, running the `test` target with Bake will evaluate the unit tests for this +project. If you want to verify that it works, you can make an arbitrary change +to `main_test.go` to cause the test to fail. + +Next, to enable linting, add another target to the Bake file, named `lint`: + +```hcl +target "lint" { + target = "lint" + output = ["type=cacheonly"] +} +``` + +And in the Dockerfile, add the build stage. This stage will use the official +`golangci-lint` image on Docker Hub. + +> [!TIP] +> Because this stage relies on executing an external dependency, it's generally +> a good idea to define the version you want to use as a build argument. This +> lets you more easily manage version upgrades in the future by collocating +> dependency versions to the beginning of the Dockerfile. + +```dockerfile {hl_lines=[2,"6-8"]} +ARG GO_VERSION="1.23" +ARG GOLANGCI_LINT_VERSION="1.61" + +#... + +FROM golangci/golangci-lint:v${GOLANGCI_LINT_VERSION}-alpine AS lint +RUN --mount=target=.,rw \ + golangci-lint run +``` + +Lastly, to enable running both tests simultaneously, you can use the `groups` +construct in the Bake file. A group can specify multiple targets to run with a +single invocation. + +```hcl +group "validate" { + targets = ["test", "lint"] +} +``` + +Now, running both tests is as simple as: + +```console +$ docker buildx bake validate +``` + +## Building variants + +Sometimes you need to build more than one version of a program. The following +example uses Bake to build separate "release" and "debug" variants of the +program, using [matrices](/manuals/build/bake/matrices.md). Using matrices lets +you run parallel builds with different configurations, saving time and ensuring +consistency. + +A matrix expands a single build into multiple builds, each representing a +unique combination of matrix parameters. This means you can orchestrate Bake +into building both the production and development build of your program in +parallel, with minimal configuration changes. + +The example project for this guide is set up to use a build-time option to +conditionally enable debug logging and tracing capabilities. + +- If you compile the program with `go build -tags="debug"`, the additional + logging and tracing capabilities are enabled (development mode). +- If you build without the `debug` tag, the program is compiled with a default + logger (production mode). + +Update the Bake file by adding a matrix attribute which defines the variable +combinations to build: + +```diff {title="docker-bake.hcl"} + target "default" { ++ matrix = { ++ mode = ["release", "debug"] ++ } ++ name = "image-${mode}" + target = "image" +``` + +The `matrix` attribute defines the variants to build ("release" and "debug"). +The `name` attribute defines how the matrix gets expanded into multiple +distinct build targets. In this case, the matrix attribute expands the build +into two workflows: `image-release` and `image-debug`, each using different +configuration parameters. + +Next, define a build argument named `BUILD_TAGS` which takes the value of the +matrix variable. + +```diff {title="docker-bake.hcl"} + target = "image" ++ args = { ++ BUILD_TAGS = mode ++ } + tags = [ +``` + +You'll also want to change how the image tags are assigned to these builds. +Currently, both matrix paths would generate the same image tag names, and +overwrite each other. Update the `tags` attribute use a conditional operator to +set the tag depending on the matrix variable value. + +```diff {title="docker-bake.hcl"} + tags = [ +- "bakeme:latest", ++ mode == "release" ? "bakeme:latest" : "bakeme:dev" + ] +``` + +- If `mode` is `release`, the tag name is `bakeme:latest` +- If `mode` is `debug`, the tag name is `bakeme:dev` + +Finally, update the Dockerfile to consume the `BUILD_TAGS` argument during the +compilation stage. When the `-tags="${BUILD_TAGS}"` option evaluates to +`-tags="debug"`, the compiler uses the `configureLogging` function in the +[`debug.go`](https://github.com/dvdksn/bakeme/blob/75c8a41e613829293c4bd3fc3b4f0c573f458f42/debug.go#L1) +file. + +```diff {title=Dockerfile} + # build compiles the program + FROM base AS build +-ARG TARGETOS TARGETARCH ++ARG TARGETOS TARGETARCH BUILD_TAGS + ENV GOOS=$TARGETOS + ENV GOARCH=$TARGETARCH + RUN --mount=target=. \ + --mount=type=cache,target=/go/pkg/mod \ +- go build -o "/usr/bin/bakeme" . ++ go build -tags="${BUILD_TAGS}" -o "/usr/bin/bakeme" . +``` + +That's all. With these changes, your `docker buildx bake` command now builds +two multi-platform image variants. You can introspect the canonical build +configuration that Bake generates using the `docker buildx bake --print` +command. Running this command shows that Bake will run a `default` group with +two targets with different build arguments and image tags. + +```json {collapse=true} +{ + "group": { + "default": { + "targets": ["image-release", "image-debug"] + } + }, + "target": { + "image-debug": { + "attest": ["type=provenance,mode=max", "type=sbom"], + "context": ".", + "dockerfile": "Dockerfile", + "args": { + "BUILD_TAGS": "debug" + }, + "tags": ["bakeme:dev"], + "target": "image", + "platforms": ["linux/amd64", "linux/arm64", "linux/riscv64"] + }, + "image-release": { + "attest": ["type=provenance,mode=max", "type=sbom"], + "context": ".", + "dockerfile": "Dockerfile", + "args": { + "BUILD_TAGS": "release" + }, + "tags": ["bakeme:latest"], + "target": "image", + "platforms": ["linux/amd64", "linux/arm64", "linux/riscv64"] + } + } +} +``` + +Factoring in all of the platform variants as well, this means that the build +configuration generates 6 different images. + +```console +$ docker buildx bake +$ docker image ls --tree + +IMAGE ID DISK USAGE CONTENT SIZE USED +bakeme:dev f7cb5c08beac 49.3MB 28.9MB +├─ linux/riscv64 0eae8ba0367a 9.18MB 9.18MB +├─ linux/arm64 56561051c49a 30MB 9.89MB +└─ linux/amd64 e8ca65079c1f 9.8MB 9.8MB + +bakeme:latest 20065d2c4d22 44.4MB 25.9MB +├─ linux/riscv64 7cc82872695f 8.21MB 8.21MB +├─ linux/arm64 e42220c2b7a3 27.1MB 8.93MB +└─ linux/amd64 af5b2dd64fde 8.78MB 8.78MB +``` + +## Exporting build artifacts + +Exporting build artifacts like binaries can be useful for deploying to +environments without Docker or Kubernetes. For example, if your programs are +meant to be run on a user's local machine. + +> [!TIP] +> The techniques discussed in this section can be applied not only to build +> output like binaries, but to any type of artifacts, such as test reports. + +With programming languages like Go and Rust where the compiled binaries are +usually portable, creating alternate build targets for exporting only the +binary is trivial. All you need to do is add an empty stage in the Dockerfile +containing nothing but the binary that you want to export. + +First, let's add a quick way to build a binary for your local platform and +export it to `./build/local` on the local filesystem. + +In the `docker-bake.hcl` file, create a new `bin` target. In this stage, set +the `output` attribute to a local filesystem path. Buildx automatically detects +that the output looks like a filepath, and exports the results to the specified +path using the [local exporter](/manuals/build/exporters/local-tar.md). + +```hcl +target "bin" { + target = "bin" + output = ["build/bin"] + platforms = ["local"] +} +``` + +Notice that this stage specifies a `local` platform. By default, if `platforms` +is unspecified, builds target the OS and architecture of the BuildKit host. If +you're using Docker Desktop, this often means builds target `linux/amd64` or +`linux/arm64`, even if your local machine is macOS or Windows, because Docker +runs in a Linux VM. Using the `local` platform forces the target platform to +match your local environment. + +Next, add the `bin` stage to the Dockerfile which copies the compiled binary +from the build stage. + +```dockerfile +FROM scratch AS bin +COPY --from=build "/usr/bin/bakeme" / +``` + +Now you can export your local platform version of the binary with `docker +buildx bake bin`. For example, on macOS, this build target generates an +executable in the [Mach-O format](https://en.wikipedia.org/wiki/Mach-O) — the +standard executable format for macOS. + +```console +$ docker buildx bake bin +$ file ./build/bin/bakeme +./build/bin/bakeme: Mach-O 64-bit executable arm64 +``` + +Next, let's add a target to build all of the platform variants of the program. +To do this, you can [inherit](/manuals/build/bake/inheritance.md) the `bin` +target that you just created, and extend it by adding the desired platforms. + +```hcl +target "bin-cross" { + inherits = ["bin"] + platforms = [ + "linux/amd64", + "linux/arm64", + "linux/riscv64", + ] +} +``` + +Now, building the `bin-cross` target creates binaries for all platforms. +Subdirectories are automatically created for each variant. + +```console +$ docker buildx bake bin-cross +$ tree build/ +build/ +└── bin + ├── bakeme + ├── linux_amd64 + │   └── bakeme + ├── linux_arm64 + │   └── bakeme + └── linux_riscv64 + └── bakeme + +5 directories, 4 files +``` + +To also generate "release" and "debug" variants, you can use a matrix just like +you did with the default target. When using a matrix, you also need to +differentiate the output directory based on the matrix value, otherwise the +binary gets written to the same location for each matrix run. + +```hcl +target "bin-all" { + inherits = ["bin-cross"] + matrix = { + mode = ["release", "debug"] + } + name = "bin-${mode}" + args = { + BUILD_TAGS = mode + } + output = ["build/bin/${mode}"] +} +``` + +```console +$ rm -r ./build/ +$ docker buildx bake bin-all +$ tree build/ +build/ +└── bin + ├── debug + │   ├── linux_amd64 + │   │   └── bakeme + │   ├── linux_arm64 + │   │   └── bakeme + │   └── linux_riscv64 + │   └── bakeme + └── release + ├── linux_amd64 + │   └── bakeme + ├── linux_arm64 + │   └── bakeme + └── linux_riscv64 + └── bakeme + +10 directories, 6 files +``` + +## Conclusion + +Docker Buildx Bake streamlines complex build workflows, enabling efficient +multi-platform builds, testing, and artifact export. By integrating Buildx Bake +into your projects, you can simplify your Docker builds, make your build +configuration portable, and wrangle complex configurations more easily. + +Experiment with different configurations and extend your Bake files to suit +your project's needs. You might consider integrating Bake into your CI/CD +pipelines to automate builds, testing, and artifact deployment.

This app consists of the +following services: + +| Service | Description | +| -------- | ---------------------------------------------------------------------- | +| `vote` | A front-end web app in Python which lets you vote between two options. | +| `result` | A Node.js web app which shows the results of the voting in real time. | +| `worker` | A .NET worker which consumes votes and stores them in the database. | +| `db` | A Postgres database backed by a Docker volume. | +| `redis` | A Redis instance which collects new votes. | +| `seed` | A utility container that seeds the database with mock data. | + +The `vote`, `result`, and `worker` services are built from code in this +repository, whereas `db` and `redis` use pre-existing Postgres and Redis images +from Docker Hub. The `seed` service is a utility that invokes requests against +the front-end service to populate the database, for testing purposes. + +## Build with Compose + +When you spin up a Docker Compose project, any services that define the `build` +property are automatically built before the service is started. Here's the +build configuration for the `vote` service in the example repository: + +```yaml {title="compose.yaml"} +services: + vote: + build: + context: ./vote # Build context + target: dev # Dockerfile stage +``` + +The `vote`, `result`, and `worker` services all have a build configuration +specified. Running `docker compose up` will trigger a build of these services. + +Did you know that you can also use Compose just to build the service images? +The `docker compose build` command lets you invoke a build using the build +configuration specified in the Compose file. For example, to build the `vote` +service with this configuration, run: + +```console +$ docker compose build vote +``` + +Omit the service name to build all services at once: + +```console +$ docker compose build +``` + +The `docker compose build` command is useful when you only need to build images +without running services. + +The Compose file format supports a number of properties for defining your +build's configuration. For example, to specify the tag name for the images, set +the `image` property on the service. + +```yaml +services: + vote: + image: username/vote + build: + context: ./vote + target: dev + #... + + result: + image: username/result + build: + context: ./result + #... + + worker: + image: username/worker + build: + context: ./worker + #... +``` + +Running `docker compose build` creates three service images with fully +qualified image names that you can push to Docker Hub. + +The `build` property supports a [wide range](/reference/compose-file/build.md) +of options for configuring builds. However, building production-grade images +are often different from images used in local development. To avoid cluttering +your Compose file with build configurations that might not be desirable for +local builds, consider separating the production builds from the local builds +by using Bake to build images for release. This approach separates concerns: +using Compose for local development and Bake for production-ready builds, while +still reusing service definitions and fundamental build configurations. + +## Build with Bake + +Like Compose, Bake parses the build definition for a project from a +configuration file. Bake supports HashiCorp Configuration Language (HCL), JSON, +and the Docker Compose YAML format. When you use Bake with multiple files, it +will find and merge all of the applicable configuration files into one unified +build configuration. The build options defined in your Compose file are +extended, or in some cases overridden, by options specified in the Bake file. + +The following section explores how you can use Bake to extend the build options +defined in your Compose file for production. + +### View the build configuration + +Bake automatically creates a build configuration from the `build` properties of +your services. Use the `--print` flag for Bake to view the build configuration +for a given Compose file. This flag evaluates the build configuration and +outputs the build definition in JSON format. + +```console +$ docker buildx bake --print +``` + +The JSON-formatted output shows the group that would be executed, and all the +targets of that group. A group is a collection of builds, and a target +represents a single build. + +```json +{ + "group": { + "default": { + "targets": [ + "vote", + "result", + "worker", + "seed" + ] + } + }, + "target": { + "result": { + "context": "result", + "dockerfile": "Dockerfile", + }, + "seed": { + "context": "seed-data", + "dockerfile": "Dockerfile", + }, + "vote": { + "context": "vote", + "dockerfile": "Dockerfile", + "target": "dev", + }, + "worker": { + "context": "worker", + "dockerfile": "Dockerfile", + } + } +} +``` + +As you can see, Bake has created a `default` group that includes four targets: + +- `seed` +- `vote` +- `result` +- `worker` + +This group is created automatically from your Compose file; it includes all of +your services containing a build configuration. To build this group of services +with Bake, run: + +```console +$ docker buildx bake +``` + +### Customize the build group + +Start by redefining the default build group that Bake executes. The current +default group includes a `seed` target — a Compose service used solely to +populate the database with mock data. Since this target doesn't produce a +production image, it doesn’t need to be included in the build group. + +To customize the build configuration that Bake uses, create a new file at the +root of the repository, alongside your `compose.yaml` file, named +`docker-bake.hcl`. + +```console +$ touch docker-bake.hcl +``` + +Open the Bake file and add the following configuration: + +```hcl {title=docker-bake.hcl} +group "default" { + targets = ["vote", "result", "worker"] +} +``` + +Save the file and print your Bake definition again. + +```console +$ docker buildx bake --print +``` + +The JSON output shows that the `default` group only includes the targets you +care about. + +```json +{ + "group": { + "default": { + "targets": ["vote", "result", "worker"] + } + }, + "target": { + "result": { + "context": "result", + "dockerfile": "Dockerfile", + "tags": ["username/result"] + }, + "vote": { + "context": "vote", + "dockerfile": "Dockerfile", + "tags": ["username/vote"], + "target": "dev" + }, + "worker": { + "context": "worker", + "dockerfile": "Dockerfile", + "tags": ["username/worker"] + } + } +} +``` + +Here, the build configuration for each target (context, tags, etc.) is picked +up from the `compose.yaml` file. The group is defined by the `docker-bake.hcl` +file. + +### Customize targets + +The Compose file currently defines the `dev` stage as the build target for the +`vote` service. That's appropriate for the image that you would run in local +development, because the `dev` stage includes additional development +dependencies and configurations. For the production image, however, you'll want +to target the `final` image instead. + +To modify the target stage used by the `vote` service, add the following +configuration to the Bake file: + +```hcl +target "vote" { + target = "final" +} +``` + +This overrides the `target` property specified in the Compose file with a +different value when you run the build with Bake. The other build options in +the Compose file (tag, context) remain unmodified. You can verify by inspecting +the build configuration for the `vote` target with `docker buildx bake --print +vote`: + +```json +{ + "group": { + "default": { + "targets": ["vote"] + } + }, + "target": { + "vote": { + "context": "vote", + "dockerfile": "Dockerfile", + "tags": ["username/vote"], + "target": "final" + } + } +} +``` + +### Additional build features + +Production-grade builds often have different characteristics from development +builds. Here are a few examples of things you might want to add for production +images. + +Multi-platform +: For local development, you only need to build images for your local platform, +since those images are just going to run on your machine. But for images that +are pushed to a registry, it's often a good idea to build for multiple +platforms, arm64 and amd64 in particular. + +Attestations +: [Attestations](/manuals/build/metadata/attestations/_index.md) are manifests +attached to the image that describe how the image was created and what +components it contains. Attaching attestations to your images helps ensure that +your images follow software supply chain best practices. + +Annotations +: [Annotations](/manuals/build/metadata/annotations.md) provide descriptive +metadata for images. Use annotations to record arbitrary information and attach +it to your image, which helps consumers and tools understand the origin, +contents, and how to use the image. + +> [!TIP] +> Why not just define these additional build options in the Compose file +> directly? +> +> The `build` property in the Compose file format does not support all build +> features. Additionally, some features, like multi-platform builds, can +> drastically increase the time it takes to build a service. For local +> development, you're better off keeping your build step simple and fast, +> saving the bells and whistles for release builds. + +To add these properties to the images you build with Bake, update the Bake file +as follows: + +```hcl +group "default" { + targets = ["vote", "result", "worker"] +} + +target "_common" { + annotations = ["org.opencontainers.image.authors=username"] + platforms = ["linux/amd64", "linux/arm64"] + attest = [ + "type=provenance,mode=max", + "type=sbom" + ] +} + +target "vote" { + inherits = ["_common"] + target = "final" +} + +target "result" { + inherits = ["_common"] +} + +target "worker" { + inherits = ["_common"] +} +``` + +This defines a new `_common` target that defines reusable build configuration +for adding multi-platform support, annotations, and attestations to your +images. The reusable target is inherited by the build targets. + +With these changes, building the project with Bake produces three sets of +multi-platform images for the `linux/amd64` and `linux/arm64` architectures. +Each image is decorated with an author annotation, and both SBOM and provenance +attestation records. + +## Conclusions + +The pattern demonstrated in this guide provides a useful approach for managing +production-ready Docker images in projects using Docker Compose.

These YAML files describe all the components and configurations of your Swarm app, and can be used to create and destroy your app in any Swarm environment. - -Now you can write a simple stack file to run and manage your Todo app, the container `getting-started` image created in [Part 2](02_our_app.md) of the tutorial. Place the following in a file called `bb-stack.yaml`: - -{{< include "swarm-compose-compat.md" >}} - -```yaml -version: '3.7' - -services: - bb-app: - image: getting-started - ports: - - "8000:3000" -``` - -In this Swarm YAML file, there is one object, a `service`, describing a scalable group of identical containers. In this case, you'll get just one container (the default), and that container will be based on your `getting-started` image created in [Part 2](02_our_app.md) of the tutorial. In addition, you've asked Swarm to forward all traffic arriving at port 8000 on your development machine to port 3000 inside our getting-started container. - -> **Kubernetes Services and Swarm Services are very different** -> -> Despite the similar name, the two orchestrators mean very different things by -> the term 'service'. In Swarm, a service provides both scheduling and -> networking facilities, creating containers and providing tools for routing -> traffic to them. In Kubernetes, scheduling and networking are handled -> separately, deployments (or other controllers) handle the scheduling of -> containers as pods, while services are responsible only for adding -> networking features to those pods. - -## Deploy and check your application - -1. Deploy your application to Swarm: - - ```console - $ docker stack deploy -c bb-stack.yaml demo - ``` - - If all goes well, Swarm will report creating all your stack objects with no complaints: - - ```shell - Creating network demo_default - Creating service demo_bb-app - ``` - - Notice that in addition to your service, Swarm also creates a Docker network by default to isolate the containers deployed as part of your stack. - -2. Make sure everything worked by listing your service: - - ```console - $ docker service ls - ``` - - If all has gone well, your service will report with 1/1 of its replicas created: - - ```shell - ID NAME MODE REPLICAS IMAGE PORTS - il7elwunymbs demo_bb-app replicated 1/1 getting-started:latest *:8000->3000/tcp - ``` - - This indicates 1/1 containers you asked for as part of your services are up and running. Also, you see that port 8000 on your development machine is getting forwarded to port 3000 in your getting-started container. - -3. Open a browser and visit your Todo app at `localhost:8000`; you should see your Todo application, the same as when you ran it as a stand-alone container in [Part 2](02_our_app.md) of the tutorial. - -4. Once satisfied, tear down your application: - - ```console - $ docker stack rm demo - ``` - -## Conclusion - -At this point, you've successfully used Docker Desktop to deploy your application to a fully-featured Swarm environment on your development machine. You can now add other components to your app and taking advantage of all the features and power of Swarm, right on your own machine. - -In addition to deploying to Swarm, you've also described your application as a stack file. This simple text file contains everything you need to create your application in a running state; you can check it in to version control and share it with your colleagues, letting you to distribute your applications to other clusters (like the testing and production clusters that probably come after your development environments). - -## Swarm and CLI references - -Further documentation for all new Swarm objects and CLI commands used in this article are available here: - - - [Swarm Mode](../../engine/swarm/_index.md) - - [Swarm Mode Services](../../engine/swarm/how-swarm-mode-works/services.md) - - [Swarm Stacks](../../engine/swarm/stack-deploy.md) - - [`docker stack *`](/reference/cli/docker/stack/) - - [`docker service *`](/reference/cli/docker/service/) \ No newline at end of file diff --git a/content/guides/dex.md b/content/guides/dex.md new file mode 100644 index 000000000000..605d6bacc17f --- /dev/null +++ b/content/guides/dex.md @@ -0,0 +1,169 @@ +--- +title: Mocking OAuth services in testing with Dex +description: &desc Mocking OAuth services in testing with Dex +keywords: Dex, container-supported development +linktitle: Mocking OAuth services with Dex +summary: *desc +tags: [app-dev, distributed-systems] +languages: [] +params: + time: 10 minutes +--- + +Dex is an open-source OpenID Connect (OIDC) and OAuth 2.0 identity provider that can be configured to authenticate against various backend identity providers, such as LDAP, SAML, and OAuth.

One of the most typical use cases is to use it inside GitHub Actions. Since Dex supports mock authentication, you can predefine test users as suggested in the [docs](https://dexidp.io/docs). The `config.yaml` file should looks like: + +```yaml +issuer: http://127.0.0.1:5556/dex + +storage: + type: memory + +web: + http: 0.0.0.0:5556 + +oauth2: + skipApprovalScreen: true + +staticClients: + - name: TestClient + id: client_test_id + secret: client_test_secret + redirectURIs: + - http://{ip-your-app}/path/to/callback/ # example: http://localhost:5555/callback + +connectors: +# mockCallback connector always returns the user 'kilgore@kilgore.trout'. +- type: mockCallback + id: mock + name: Mock +``` +Now you can insert the Dex service inside your `~/.github/workflows/ci.yaml` file: + +```yaml +[...] +jobs: + test-oauth: + runs-on: ubuntu-latest + steps: + - name: Install Dex + run: | + curl -L https://github.com/dexidp/dex/releases/download/v2.37.0/dex_linux_amd64 -o dex + chmod +x dex + + - name: Start Dex Server + run: | + nohup ./dex serve config.yaml > dex.log 2>&1 & + sleep 5 # Give Dex time to start +[...] +``` + + +### Conclusion + +By following this guide, you've set up Dex as an OAuth mock server using Docker.

Copy all of the files from your project on your machine into the container image by using the `COPY` instruction: - - ```dockerfile - COPY . . - ``` - -6. Install the app's dependencies by using the `yarn` CLI and package manager. To do so, run a command using the `RUN` instruction: - - ```dockerfile - RUN yarn install --production - ``` - -7. Finally, specify the default command to run by using the `CMD` instruction: - - ```dockerfile - CMD ["node", "./src/index.js"] - ``` - And with that, you should have the following Dockerfile: - - - ```dockerfile - FROM node:20-alpine - WORKDIR /app - COPY . . - RUN yarn install --production - CMD ["node", "./src/index.js"] - ``` - -> **This Dockerfile isn't production-ready yet** -> -> It's important to note that this Dockerfile is _not_ following all -> of the best practices yet (by design).

Why should I use Docker Compose for Laravel? + +Docker Compose is a powerful tool for managing multi-container environments, particularly in development due to its simplicity. With Docker Compose, you can define and connect all necessary services for Laravel, such as PHP, Nginx, and databases, in a single configuration (`compose.*.yaml`). This setup ensures consistency across development, testing, and production environments, streamlining onboarding and reducing discrepancies between local and server setups. + +While Docker Compose is a great choice for development, tools like **Docker Swarm** or **Kubernetes** offer advanced scaling and orchestration features, which may be beneficial for complex production deployments. + +## 2. How do I debug my Laravel application with Docker Compose? + +To debug your Laravel application in a Docker environment, use **Xdebug**. In the development setup, Xdebug is installed in the `php-fpm` container to enable debugging. Ensure Xdebug is enabled in your `compose.dev.yaml` file by setting the environment variable `XDEBUG_ENABLED=true` and configuring your IDE (e.g., Visual Studio Code or PHPStorm) to connect to the remote container for debugging. + +## 3. Can I use Docker Compose with databases other than PostgreSQL? + +Yes, Docker Compose supports various database services for Laravel. While PostgreSQL is used in the examples, you can easily substitute **MySQL**, **MariaDB**, or even **SQLite**. Update the `compose.*.yaml` file to specify the required Docker image and adjust your `.env` file to reflect the new database configuration. + +## 4. How can I persist data in development and production? + +In both development and production, Docker volumes are used to persist data. For instance, in the `compose.*.yaml` file, the `postgres-data-*` volume stores PostgreSQL data, ensuring that data is retained even if the container restarts. You can also define named volumes for other services where data persistence is essential. + +## 5. What is the difference between development and production Docker configurations? + +In a development environment, Docker configurations include tools that streamline coding and debugging, such as Xdebug for debugging, and volume mounts to enable real-time code updates without requiring image rebuilds. + +In production, the configuration is optimized for performance, security, and efficiency. This setup uses multi-stage builds to keep the image lightweight and includes only essential tools, packages, and libraries. + +It’s recommended to use `alpine`-based images in production for smaller image sizes, enhancing deployment speed and security. + +Additionally, consider using [Docker Scout](/manuals/scout/_index.md) to detect and analyze vulnerabilities, especially in production environments. + +For additional information about using Docker Compose in production, see [this guide](/compose/how-tos/production/). diff --git a/content/guides/frameworks/laravel/development-setup.md b/content/guides/frameworks/laravel/development-setup.md new file mode 100644 index 000000000000..3c19940f9683 --- /dev/null +++ b/content/guides/frameworks/laravel/development-setup.md @@ -0,0 +1,327 @@ +--- +title: Laravel Development Setup with Docker Compose +description: Set up a Laravel development environment using Docker Compose. +weight: 30 +--- + +This guide demonstrates how to configure a **development** environment for a Laravel application using Docker and Docker Compose.

This guide focuses on a specialized RAG implementation using graph databases like Neo4j, which excel in managing highly connected, relational data. Unlike traditional RAG setups with vector databases, combining RAG with graph databases offers better context-awareness and relationship-driven insights. + +In this guide, you will: + +* Explore the advantages of integrating graph databases into a RAG framework. +* Configure a GenAI stack with Docker, incorporating Neo4j and an AI model. +* Analyze a real-world case study that highlights the effectiveness of this approach for handling specialized queries. + +## Understanding RAG + +RAG is a hybrid framework that enhances the capabilities of large language models by integrating information retrieval. It combines three core components: + +- **Information retrieval** from an external knowledge base +- **Large Language Model (LLM)** for generating responses +- **Vector embeddings** to enable semantic search + +In a RAG system, vector embeddings are used to represent the semantic meaning of text in a way that a machine can understand and process. For instance, the words "dog" and "puppy" will have similar embeddings because they share similar meanings. By integrating these embeddings into the RAG framework, the system can combine the generative power of large language models with the ability to pull in highly relevant, contextually-aware data from external sources. + +The system operates as follows: +1. Questions get turned into mathematical patterns that capture their meaning +2. These patterns help find matching information in a database +3. The LLM generates responses that blend the model's inherent knowledge with the this extra information. + +To hold this vector information in an efficient manner, we need a special type of database. + +## Introduction to Graph databases + +Graph databases, such as Neo4j, are specifically designed for managing highly connected data. Unlike traditional relational databases, graph databases prioritize both the entities and the relationships between them, making them ideal for tasks where connections are as important as the data itself. + +Graph databases stand out for their unique approach to data storage and querying. They use nodes (or vertices) to represent entities and edges to represent the relationships between these entities. This structure allows for efficient handling of highly connected data and complex queries, which are difficult to manage in traditional database systems. + +SQL databases and graph databases differ significantly in their data models. SQL databases use a tabular structure with rows and columns, where relationships between entities are established using foreign keys. This approach works well for structured data and predefined relationships. In contrast, graph databases represent data as nodes (entities) and edges (relationships), making the representation of relationships more intuitive and flexible. This structure is particularly advantageous for complex, interconnected data. + +Another key difference lies in schema flexibility. SQL databases operate on a rigid schema, meaning any changes to the data structure, such as adding new columns or altering relationships, typically require careful planning and migration processes. Graph databases, however, are schema-optional, allowing for much greater flexibility. New nodes, edges, or properties can be introduced without disrupting existing data, enabling faster adaptation to changing requirements. + +## Practical implementation: testing RAG effectiveness + +To illustrate the power of RAG systems in practice, let's examine a real-world implementation using Apache NiFi as our subject matter. This case study demonstrates how RAG can enhance an AI's ability to provide accurate, contextual information about specialized technical topics. + +### Teaching AI about new technologies + +Apache NiFi serves as an excellent example of the limitations of traditional LLMs and how RAG can overcome them. As a relatively recent technology, many LLMs have limited or outdated knowledge about it, making it a perfect candidate for demonstrating RAG's capabilities. + +Without RAG, the LLM may provide broad responses or acknowledge its limited knowledge when asked about information that is beyond its cutoff date. The following example demonstrates this. +```text +Question: What important events happened in 2024? +RAG: Disabled +I'm happy to help! Unfortunately, I'm a large language model, I don't have access to real-time information or events that occurred after my training data cutoff in 2024. Therefore, I cannot provide you with any important events that happened in 2024. My apologize for any inconvenience this may cause. Is there anything else I can help you with? +``` + +## Setting up GenAI stack with GPU acceleration on Linux + +To set up and run the GenAI stack on a Linux host, execute one of the following commands, either for GPU or CPU powered: + +### GPU powered + +```bash +git clone https://github.com/docker/genai-stack +docker compose --profile linux-gpu up -d +mv env.example .env +nano .env +``` +In the `.env` file, make sure following lines are commented out.

Run the following command to view the logs: + +```bash +docker compose logs +``` + +Wait for specific lines in the logs indicating that the download is complete and the stack is ready. These lines typically confirm successful setup and initialization. + + ```text + pull-model-1 exited with code 0 + database-1 | 2024-12-29 09:35:53.269+0000 INFO Started. + pdf_bot-1 | You can now view your Streamlit app in your browser. + loader-1 | You can now view your Streamlit app in your browser. + bot-1 | You can now view your Streamlit app in your browser. + ``` + +You can now access the interface at [http://localhost:8501/](http://localhost:8501/) to ask questions. For example, you can try the sample question: + +When we see those lines in the logs, web apps are ready to be used. + +Since our goal is to teach AI about things it does not yet know, we begin by asking it a simple question about Nifi at +[http://localhost:8501/](http://localhost:8501/). +![alt text](image.png) + +```text +Question: What is Apache Nifi? +RAG: Disabled +Hello! I'm here to help you with your question about Apache NiFi. Unfortunately, I don't know the answer to that question. I'm just an AI and my knowledge cutoff is December 2022, so I may not be familiar with the latest technologies or software. Can you please provide more context or details about Apache NiFi? Maybe there's something I can help you with related to it. +``` + +As we can see, AI does not know anything about this subject because it did not exist during the time of its training, also known as the information cutoff point. + +Now it's time to teach the AI some new tricks. First, connect to [http://localhost:8502/](http://localhost:8502/). Instead of using the "neo4j" tag, change it to the "apache-nifi" tag, then select the **Import** button. + +![alt text](image-1.png) + +After the import is successful, we can access Neo4j to verify the data. + +After logging in to [http://localhost:7474/](http://localhost:7474/) using the credentials from the `.env` file, you can run queries on Neo4j. Using the Neo4j Cypher query language, you can check for the data stored in the database. + +To count the data, run the following query: + +```text +MATCH (n) +RETURN DISTINCT labels(n) AS NodeTypes, count(*) AS Count +ORDER BY Count DESC; +``` + +To execute this query, write in the box on the top and select the blue run button. + +![alt text](image-2.png) + +Results will appear below. What we are seeing here is the information system downloaded from Stack Overflow and saved in the graph database. RAG will utilize this information to enhance its responses. + +You can also run the following query to visualize the data: + +```text +CALL db.schema.visualization() +``` + +To check the relationships in the database, run the following query: + +```text +CALL db.relationshipTypes() +``` + +Now, we are ready to enable our LLM to use this information. Go back to [http://localhost:8501/](http://localhost:8501/), enable the **RAG** checkbox, and ask the same question again. The LLM will now provide a more detailed answer. + +![alt text](image-3.png) + +The system delivers comprehensive, accurate information by pulling from current technical documentation. +```text +Question: What is Apache Nifi? +RAG: Enabled + +Answer: +Apache NiFi is an open-source, distributed data processing system that allows you to collect, transform, and transport data across various sources and sinks. It provides a graphical user interface for designing and managing data flows, as well as a set of APIs for integrating with other systems. +According to this Stack Overflow question, the free Neo4J JDBC driver doesn't understand SQL, only Cypher, so you would need to use a non-free BI Connector to connect to Neo4j from Apache Drill. +Additionally, this Stack Overflow question suggests that Apache POI does work in a Neo4j User Defined Function. However, there may be an unknown glitch in the standalone UDF mentioned in the initial question. +To export data from Neo4j to Excel using APOC Extended procedures, you can use apoc.export.xls.query which takes a Cypher query and exports the results to an Excel file. + +References: +How to connect and query Neo4j Database on Apache Drill? +Is a Neo4j UDF compatible with Apache POI? +``` + +Keep in mind that new questions will be added to Stack Overflow, and due to the inherent randomness in most AI models, the answers may vary and won't be identical to those in this example. + +Feel free to start over with another [Stack Overflow tag](https://stackoverflow.com/tags). To drop all data in Neo4j, you can use the following command in the Neo4j Web UI: + +```txt +MATCH (n) +DETACH DELETE n; +``` + +For optimal results, choose a tag that the LLM is not familiar with. + +### When to leverage RAG for optimal results + +Retrieval-Augmented Generation (RAG) is particularly effective in scenarios where standard Large Language Models (LLMs) fall short. The three key areas where RAG excels are knowledge limitations, business requirements, and cost efficiency. Below, we explore these aspects in more detail. + +#### Overcoming knowledge limitations + +LLMs are trained on a fixed dataset up until a certain point in time. This means they lack access to: + +* Real-time information: LLMs do not continuously update their knowledge, so they may not be aware of recent events, newly released research, or emerging technologies. +* Specialized knowledge: Many niche subjects, proprietary frameworks, or industry-specific best practices may not be well-documented in the model’s training corpus. +* Accurate contextual understanding: LLMs can struggle with nuances or evolving terminologies that frequently change within dynamic fields like finance, cybersecurity, or medical research. + +By incorporating RAG with a graph database such as Neo4j, AI models can access and retrieve the latest, relevant, and highly connected data before generating a response. This ensures that answers are up-to-date and grounded in factual information rather than inferred approximations. + +#### Addressing business and compliance needs + +Organizations in industries like healthcare, legal services, and financial analysis require their AI-driven solutions to be: + +* Accurate: Businesses need AI-generated content that is factual and relevant to their specific domain. +* Compliant: Many industries must adhere to strict regulations regarding data usage and security. +* Traceable: Enterprises often require AI responses to be auditable, meaning they need to reference source material. + +By using RAG, AI-generated answers can be sourced from trusted databases, ensuring higher accuracy and compliance with industry standards. This mitigates risks such as misinformation or regulatory violations. + +#### Enhancing cost efficiency and performance + +Training and fine-tuning large AI models can be computationally expensive and time-consuming. However, integrating RAG provides: + +* Reduced fine-tuning needs: Instead of retraining an AI model every time new data emerges, RAG allows the model to fetch and incorporate updated information dynamically. +* Better performance with smaller models: With the right retrieval techniques, even compact AI models can perform well by leveraging external knowledge efficiently. +* Lower operational costs: Instead of investing in expensive infrastructure to support large-scale retraining, businesses can optimize resources by utilizing RAG’s real-time retrieval capabilities. + +By following this guide, you now have the foundational knowledge to implement RAG with Neo4j, enabling your AI system to deliver more accurate, relevant, and insightful responses. The next step is experimentation—choose a dataset, configure your stack, and start enhancing your AI with the power of retrieval-augmented generation. \ No newline at end of file diff --git a/content/guides/genai-pdf-bot/_index.md b/content/guides/genai-pdf-bot/_index.md new file mode 100644 index 000000000000..41c5e16626e7 --- /dev/null +++ b/content/guides/genai-pdf-bot/_index.md @@ -0,0 +1,20 @@ +--- +title: PDF analysis and chat +description: Containerize generative AI (GenAI) apps using Docker +keywords: python, generative ai, genai, llm, neo4j, ollama, langchain +summary: | + Learn how to build a PDF bot for parsing PDF documents and generating + responses using Docker and generative AI. +tags: [ai] +aliases: + - /guides/use-case/genai-pdf-bot/ +params: + time: 20 minutes +--- + +The generative AI (GenAI) guide teaches you how to containerize an existing GenAI application using Docker.

This means the application +will operate as intended within its Docker containers, regardless of the +underlying system differences. To learn more about Docker, see the [Getting started overview](/get-started/introduction/_index.md). + +Docker Compose is a tool for defining and running multi-container applications. +Compose makes it easy to run this application with a single command, `docker +compose up`. For more details, see the [Compose overview](/manuals/compose/_index.md). + +### OpenAI API + +The OpenAI API provides an LLM service that's known for its cutting-edge AI and +machine learning technologies. In this application, OpenAI's technology is used +to generate transcriptions from audio (using the Whisper model) and to create +embeddings for text data, as well as to generate responses to user queries +(using GPT and chat completions). For more details, see +[openai.com](https://openai.com/product). + +### Whisper + +Whisper is an automatic speech recognition system developed by OpenAI, designed +to transcribe spoken language into text. In this application, Whisper is used to +transcribe the audio from YouTube videos into text, enabling further processing +and analysis of the video content. For more details, see [Introducing Whisper](https://openai.com/research/whisper). + +### Embeddings + +Embeddings are numerical representations of text or other data types, which +capture their meaning in a way that can be processed by machine learning +algorithms. In this application, embeddings are used to convert video +transcriptions into a vector format that can be queried and analyzed for +relevance to user input, facilitating efficient search and response generation +in the application. For more details, see OpenAI's +[Embeddings](https://platform.openai.com/docs/guides/embeddings) documentation. + +![Embedding diagram](images/embeddings.webp) + +### Chat completions + +Chat completion, as utilized in this application through OpenAI's API, refers to +the generation of conversational responses based on a given context or prompt. +In the application, it is used to provide intelligent, context-aware answers to +user queries by processing and integrating information from video transcriptions +and other inputs, enhancing the chatbot's interactive capabilities. For more +details, see OpenAI's +[Chat Completions API](https://platform.openai.com/docs/guides/text-generation) documentation. + +### Pinecone + +Pinecone is a vector database service optimized for similarity search, used for +building and deploying large-scale vector search applications. In this +application, Pinecone is employed to store and retrieve the embeddings of video +transcriptions, enabling efficient and relevant search functionality within the +application based on user queries. For more details, see +[pincone.io](https://www.pinecone.io/). + +### Retrieval-Augmented Generation + +Retrieval-Augmented Generation (RAG) is a technique that combines information +retrieval with a language model to generate responses based on retrieved +documents or data. In RAG, the system retrieves relevant information (in this +case, via embeddings from video transcriptions) and then uses a language model +to generate responses based on this retrieved data.

Next, under **Variables**, create a `DOCKER_USERNAME` repository variable + containing your Docker Hub username. + +## Set up your GitHub Actions workflow + +GitHub Actions workflows define a series of steps to automate tasks, such as +building and pushing Docker images, in response to triggers like commits or +pull requests. In this guide, the workflow focuses on automating Docker builds +and testing, ensuring your containerized application works correctly before +publishing it. + +Create a file named `docker-ci.yml` in the `.github/workflows/` directory of +your repository. Start with the basic workflow configuration: + +```yaml +name: Build and Push Docker Image + +on: + push: + branches: + - main + pull_request: +``` + +This configuration runs the workflow on pushes to the main branch and on pull +requests. By including both triggers, you can ensure that the image builds +correctly for a pull request before it's merged. + +## Extract metadata for tags and annotations + +For the first step in your workflow, use the `docker/metadata-action` to +generate metadata for your image. This action extracts information about your +Git repository, such as branch names and commit SHAs, and generates image +metadata such as tags and annotations. + +Add the following YAML to your workflow file: + +```yaml +jobs: + build: + runs-on: ubuntu-latest + steps: + - name: Checkout + uses: actions/checkout@v4 + - name: Extract Docker image metadata + id: meta + uses: docker/metadata-action@{{% param "metadata_action_version" %}} + with: + images: ${{ vars.DOCKER_USERNAME }}/my-image +``` + +These steps prepare metadata to tag and annotate your images during the build +and push process. + +- The **Checkout** step clones the Git repository. +- The **Extract Docker image metadata** step extracts Git metadata and + generates image tags and annotations for the Docker build. + +## Authenticate to your registry + +Before you build the image, authenticate to your registry to ensure that you +can push your built image to the registry. + +To authenticate with Docker Hub, add the following step to your workflow: + +```yaml + - name: Log in to Docker Hub + uses: docker/login-action@{{% param "login_action_version" %}} + with: + username: ${{ vars.DOCKER_USERNAME }} + password: ${{ secrets.DOCKER_PASSWORD }} +``` + +This step uses the Docker credentials [configured in the repository settings](#configure-your-github-repository). + +## Build and push the image + +Finally, build the final production image and push it to your registry. The +following configuration builds the image and pushes it directly to a registry. + +```yaml + - name: Build and push Docker image + uses: docker/build-push-action@{{% param "build_push_action_version" %}} + with: + push: ${{ github.event_name != 'pull_request' }} + tags: ${{ steps.meta.outputs.tags }} + annotations: ${{ steps.meta.outputs.annotations }} +``` + +In this configuration: + +- `push: ${{ github.event_name != 'pull_request' }}` ensures that images are + only pushed when the event is not a pull request.

One of the most popular monitoring tools is Prometheus. Prometheus is an open-source monitoring and alerting toolkit that is designed for reliability and scalability. It collects metrics from monitored targets by scraping metrics HTTP endpoints on these targets. To visualize the metrics, you can use Grafana. Grafana is an open-source platform for monitoring and observability that allows you to query, visualize, alert on, and understand your metrics no matter where they are stored. + +In this guide, you will be creating a Golang server with some endpoints to simulate a real-world application. Then you will expose metrics from the server using Prometheus. Finally, you will visualize the metrics using Grafana.

Then you have defined a couple of variables, `HttpRequestTotal` and `HttpRequestErrorTotal` are Prometheus counter metrics, and `customRegistry` is a custom registry that will be used to register these metrics. The name of the metric is a string that you can use to identify the metric. The help string is a string that will be shown when you query the `/metrics` endpoint to understand the metric. The reason you are using the custom registry is so avoid the default Go metrics that are registered by default by the Prometheus client. Then using the `init` function you are registering the metrics with the custom registry. + +```go +import ( + "strconv" + + "github.com/gin-gonic/gin" + "github.com/prometheus/client_golang/prometheus" + "github.com/prometheus/client_golang/prometheus/promhttp" +) + +// Define metrics +var ( + HttpRequestTotal = prometheus.NewCounterVec(prometheus.CounterOpts{ + Name: "api_http_request_total", + Help: "Total number of requests processed by the API", + }, []string{"path", "status"}) + + HttpRequestErrorTotal = prometheus.NewCounterVec(prometheus.CounterOpts{ + Name: "api_http_request_error_total", + Help: "Total number of errors returned by the API", + }, []string{"path", "status"}) +) + +// Custom registry (without default Go metrics) +var customRegistry = prometheus.NewRegistry() + +// Register metrics with custom registry +func init() { + customRegistry.MustRegister(HttpRequestTotal, HttpRequestErrorTotal) +} +``` + +In the `main` function, you have created a new instance of the `gin` framework and created three routes. You can see the health endpoint that is on path `/health` that will return a JSON with `{"message": "Up and running!"}` and the `/v1/users` endpoint that will return a JSON with `{"message": "Hello from /v1/users"}`. The third route is for the `/metrics` endpoint that will return the metrics in the Prometheus format. Then you have `RequestMetricsMiddleware` middleware, it will be called for every request made to the API. It will record the incoming requests metrics like status codes and paths. Finally, you are running the gin application on port 8000. + +```golang +func main() { + router := gin.Default() + + // Register /metrics before middleware + router.GET("/metrics", PrometheusHandler()) + + router.Use(RequestMetricsMiddleware()) + router.GET("/health", func(c *gin.Context) { + c.JSON(200, gin.H{ + "message": "Up and running!", + }) + }) + router.GET("/v1/users", func(c *gin.Context) { + c.JSON(200, gin.H{ + "message": "Hello from /v1/users", + }) + }) + + router.Run(":8000") +} +``` + +Now comes the middleware function `RequestMetricsMiddleware`. This function is called for every request made to the API. It increments the `HttpRequestTotal` counter (different counter for different paths and status codes) if the status code is less than or equal to 400. If the status code is greater than 400, it increments the `HttpRequestErrorTotal` counter (different counter for different paths and status codes). The `PrometheusHandler` function is the custom handler that will be called for the `/metrics` endpoint.

Now it's time to run and test if the app is registering metrics correctly. + +## Running the application + +Make sure you are still inside `go-prometheus-monitoring` directory in the terminal, and run the following command. Install the dependencies by running `go mod tidy` and then build and run the application by running `go run main.go`. Then visit `http://localhost:8000/health` or `http://localhost:8000/v1/users`. You should see the output `{"message": "Up and running!"}` or `{"message": "Hello from /v1/users"}`. If you are able to see this then your app is successfully up and running. + + +Now, check your application's metrics by accessing the `/metrics` endpoint. +Open `http://localhost:8000/metrics` in your browser.

It exposes the application's port `8000` and connects to the `go-network` network. It also defines a health check to monitor the application's health. You have also used `healthcheck` to monitor the health of the application. The health check runs every 30 seconds and retries 5 times if the health check fails. The health check uses the `curl` command to check the `/health` endpoint of the application. Apart from the health check, you have also added a `develop` section to watch the changes in the application's source code and rebuild the application using the Docker Compose Watch feature. + +- **Prometheus service**: This service runs the Prometheus server in a container. It uses the official Prometheus image `prom/prometheus:v2.55.0`. It exposes the Prometheus server on port `9090` and connects to the `go-network` network. You have also mounted the `prometheus.yml` file from the `Docker` directory which is present in the root directory of your project. The `prometheus.yml` file contains the Prometheus configuration to scrape the metrics from the Golang application. This is how you connect the Prometheus server to the Golang application. + + ```yaml + global: + scrape_interval: 10s + evaluation_interval: 10s + + scrape_configs: + - job_name: myapp + static_configs: + - targets: ["api:8000"] + ``` + + In the `prometheus.yml` file, you have defined a job named `myapp` to scrape the metrics from the Golang application. The `targets` field specifies the target to scrape the metrics from. In this case, the target is the Golang application running on port `8000`. The `api` is the service name of the Golang application in the Docker Compose file. The Prometheus server will scrape the metrics from the Golang application every 10 seconds. + +- **Grafana service**: This service runs the Grafana server in a container. It uses the official Grafana image `grafana/grafana:11.3.0`. It exposes the Grafana server on port `3000` and connects to the `go-network` network. You have also mounted the `grafana.yml` file from the `Docker` directory which is present in the root directory of your project. The `grafana.yml` file contains the Grafana configuration to add the Prometheus data source. This is how you connect the Grafana server to the Prometheus server. In the environment variables, you have set the Grafana admin user and password, which will be used to log in to the Grafana dashboard. + + ```yaml + apiVersion: 1 + datasources: + - name: Prometheus (Main) + type: prometheus + url: http://prometheus:9090 + isDefault: true + ``` + + In the `grafana.yml` file, you have defined a Prometheus data source named `Prometheus (Main)`. The `type` field specifies the type of the data source, which is `prometheus`. The `url` field specifies the URL of the Prometheus server to fetch the metrics from. In this case, the URL is `http://prometheus:9090`. `prometheus` is the service name of the Prometheus server in the Docker Compose file. The `isDefault` field specifies whether the data source is the default data source in Grafana. + +Apart from the services, the Docker Compose file also defines a volume named `grafana-data` to persist the Grafana data and a network named `go-network` to connect the services together. You have created a custom network `go-network` to connect the services together. The `driver: bridge` field specifies the network driver to use for the network. + +## Building and running the services + +Now that you have the Docker Compose file, you can build the services and run them together using Docker Compose. + +To build and run the services, run the following command in the terminal: + +```console +$ docker compose up +``` + +The `docker compose up` command builds the services defined in the Docker Compose file and runs them together.

The last +parameter tells Docker where you want that file to be copied to. + +Copy the `go.mod` and `go.sum` file into your project directory `/app` which, +owing to your use of `WORKDIR`, is the current directory (`./`) inside the +image. Unlike some modern shells that appear to be indifferent to the use of +trailing slash (`/`), and can figure out what the user meant (most of the time), +Docker's `COPY` command is quite sensitive in its interpretation of the trailing +slash. + +```dockerfile +COPY go.mod go.sum ./ +``` + +> [!NOTE] +> +> If you'd like to familiarize yourself with the trailing slash treatment by the +> `COPY` command, see [Dockerfile +> reference](/reference/dockerfile.md#copy). This trailing slash can +> cause issues in more ways than you can imagine. + +Now that you have the module files inside the Docker image that you are +building, you can use the `RUN` command to run the command `go mod download` +there as well. This works exactly the same as if you were running `go` locally +on your machine, but this time these Go modules will be installed into a +directory inside the image. + +```dockerfile +RUN go mod download +``` + +At this point, you have a Go toolchain version 1.19.x and all your Go +dependencies installed inside the image. + +The next thing you need to do is to copy your source code into the image. You’ll +use the `COPY` command just like you did with your module files before. + +```dockerfile +COPY *.go ./ +``` + +This `COPY` command uses a wildcard to copy all files with `.go` extension +located in the current directory on the host (the directory where the `Dockerfile` +is located) into the current directory inside the image. + +Now, to compile your application, use the familiar `RUN` command: + +```dockerfile +RUN CGO_ENABLED=0 GOOS=linux go build -o /docker-gs-ping +``` + +This should be familiar. The result of that command will be a static application +binary named `docker-gs-ping` and located in the root of the filesystem of the +image that you are building. You could have put the binary into any other place +you desire inside that image, the root directory has no special meaning in this +regard. It's just convenient to use it to keep the file paths short for improved +readability. + +Now, all that is left to do is to tell Docker what command to run when your +image is used to start a container. + +You do this with the `CMD` command: + +```dockerfile +CMD ["/docker-gs-ping"] +``` + +Here's the complete `Dockerfile`: + +```dockerfile +# syntax=docker/dockerfile:1 + +FROM golang:1.19 + +# Set destination for COPY +WORKDIR /app + +# Download Go modules +COPY go.mod go.sum ./ +RUN go mod download + +# Copy the source code. Note the slash at the end, as explained in +# https://docs.docker.com/reference/dockerfile/#copy +COPY *.go ./ + +# Build +RUN CGO_ENABLED=0 GOOS=linux go build -o /docker-gs-ping + +# Optional: +# To bind to a TCP port, runtime parameters must be supplied to the docker command. +# But we can document in the Dockerfile what ports +# the application is going to listen on by default. +# https://docs.docker.com/reference/dockerfile/#expose +EXPOSE 8080 + +# Run +CMD ["/docker-gs-ping"] +``` + +The `Dockerfile` may also contain comments. They always begin with a `#` symbol, +and must be at the beginning of a line. Comments are there for your convenience +to allow documenting your `Dockerfile`. + +There is also a concept of Dockerfile directives, such as the `syntax` directive +you added. The directives must always be at the very top of the `Dockerfile`, so +when adding comments, make sure that the comments follow after any directives +that you may have used: + +```dockerfile +# syntax=docker/dockerfile:1 +# A sample microservice in Go packaged into a container image. + +FROM golang:1.19 + +# ... +``` + +## Build the image + +Now that you've created your `Dockerfile`, build an image from it. The `docker +build` command creates Docker images from the `Dockerfile` and a context. A +build context is the set of files located in the specified path or URL. The +Docker build process can access any of the files located in the context. + +The build command optionally takes a `--tag` flag. This flag is used to label +the image with a string value, which is easy for humans to read and recognize. +If you don't pass a `--tag`, Docker will use `latest` as the default value. + +Build your first Docker image. + +```console +$ docker build --tag docker-gs-ping . +``` + +The build process will print some diagnostic messages as it goes through the build steps. +The following is just an example of what these messages may look like. + +```console +[+] Building 2.2s (15/15) FINISHED + => [internal] load build definition from Dockerfile 0.0s + => => transferring dockerfile: 701B 0.0s + => [internal] load .dockerignore 0.0s + => => transferring context: 2B 0.0s + => resolve image config for docker.io/docker/dockerfile:1 1.1s + => CACHED docker-image://docker.io/docker/dockerfile:1@sha256:39b85bbfa7536a5feceb7372a0817649ecb2724562a38360f4d6a7782a409b14 0.0s + => [internal] load build definition from Dockerfile 0.0s + => [internal] load .dockerignore 0.0s + => [internal] load metadata for docker.io/library/golang:1.19 0.7s + => [1/6] FROM docker.io/library/golang:1.19@sha256:5d947843dde82ba1df5ac1b2ebb70b203d106f0423bf5183df3dc96f6bc5a705 0.0s + => [internal] load build context 0.0s + => => transferring context: 6.08kB 0.0s + => CACHED [2/6] WORKDIR /app 0.0s + => CACHED [3/6] COPY go.mod go.sum ./ 0.0s + => CACHED [4/6] RUN go mod download 0.0s + => CACHED [5/6] COPY *.go ./ 0.0s + => CACHED [6/6] RUN CGO_ENABLED=0 GOOS=linux go build -o /docker-gs-ping 0.0s + => exporting to image 0.0s + => => exporting layers 0.0s + => => writing image sha256:ede8ff889a0d9bc33f7a8da0673763c887a258eb53837dd52445cdca7b7df7e3 0.0s + => => naming to docker.io/library/docker-gs-ping 0.0s +``` + +Your exact output will vary, but provided there aren't any errors, you should +see the word `FINISHED` in the first line of output. This means Docker has +successfully built your image named `docker-gs-ping`. + +## View local images + +To see the list of images you have on your local machine, you have two options. +One is to use the CLI and the other is to use [Docker +Desktop](/manuals/desktop/_index.md). Since you're currently working in the +terminal, take a look at listing images with the CLI. + +To list images, run the `docker image ls`command (or the `docker images` shorthand): + +```console +$ docker image ls + +REPOSITORY TAG IMAGE ID CREATED SIZE +docker-gs-ping latest 7f153fbcc0a8 2 minutes ago 1.11GB +... +``` + +Your exact output may vary, but you should see the `docker-gs-ping` image with +the `latest` tag. Because you didn't specify a custom tag when you built your +image, Docker assumed that the tag would be `latest`, which is a special value. + +## Tag images + +An image name is made up of slash-separated name components. Name components may +contain lowercase letters, digits, and separators. A separator is defined as a +period, one or two underscores, or one or more dashes. A name component may not +start or end with a separator. + +An image is made up of a manifest and a list of layers. In simple terms, a tag +points to a combination of these artifacts. You can have multiple tags for the +image and, in fact, most images have multiple tags. Create a second tag +for the image you built and take a look at its layers. + +Use the `docker image tag` (or `docker tag` shorthand) command to create a new +tag for your image. This command takes two arguments; the first argument is the +source image, and the second is the new tag to create. The following command +creates a new `docker-gs-ping:v1.0` tag for the `docker-gs-ping:latest` you +built: + +```console +$ docker image tag docker-gs-ping:latest docker-gs-ping:v1.0 +``` + +The Docker `tag` command creates a new tag for the image. It doesn't create a +new image. The tag points to the same image and is just another way to reference +the image. + +Now run the `docker image ls` command again to see the updated list of local +images: + +```console +$ docker image ls + +REPOSITORY TAG IMAGE ID CREATED SIZE +docker-gs-ping latest 7f153fbcc0a8 6 minutes ago 1.11GB +docker-gs-ping v1.0 7f153fbcc0a8 6 minutes ago 1.11GB +... +``` + +You can see that you have two images that start with `docker-gs-ping`. You know +they're the same image because if you look at the `IMAGE ID` column, you can +see that the values are the same for the two images. This value is a unique +identifier Docker uses internally to identify the image. + +Remove the tag that you just created. To do this, you’ll use the +`docker image rm` command, or the shorthand `docker rmi` (which stands for +"remove image"): + +```console +$ docker image rm docker-gs-ping:v1.0 +Untagged: docker-gs-ping:v1.0 +``` + +Notice that the response from Docker tells you that the image hasn't been +removed but only untagged. + +Verify this by running the following command: + +```console +$ docker image ls +``` + +You will see that the tag `v1.0` is no longer in the list of images kept by your Docker instance. + +```text +REPOSITORY TAG IMAGE ID CREATED SIZE +docker-gs-ping latest 7f153fbcc0a8 7 minutes ago 1.11GB +... +``` + +The tag `v1.0` has been removed but you still have the `docker-gs-ping:latest` +tag available on your machine, so the image is there. + +## Multi-stage builds + +You may have noticed that your `docker-gs-ping` image weighs in at over a +gigabyte, which is a lot for a tiny compiled Go application. You may also be +wondering what happened to the full suite of Go tools, including the compiler, +after you had built your image. + +The answer is that the full toolchain is still there, in the container image. +Not only this is inconvenient because of the large file size, but it may also +present a security risk when the container is deployed. + +These two issues can be solved by using [multi-stage builds](/manuals/build/building/multi-stage.md). + +In a nutshell, a multi-stage build can carry over the artifacts from one build stage into another, +and every build stage can be instantiated from a different base image. + +Thus, in the following example, you are going to use a full-scale official Go +image to build your application. Then you'll copy the application binary into +another image whose base is very lean and doesn't include the Go toolchain or +other optional components. + +The `Dockerfile.multistage` in the sample application's repository has the +following content: + +```dockerfile +# syntax=docker/dockerfile:1 + +# Build the application from source +FROM golang:1.19 AS build-stage + +WORKDIR /app + +COPY go.mod go.sum ./ +RUN go mod download + +COPY *.go ./ + +RUN CGO_ENABLED=0 GOOS=linux go build -o /docker-gs-ping + +# Run the tests in the container +FROM build-stage AS run-test-stage +RUN go test -v ./... + +# Deploy the application binary into a lean image +FROM gcr.io/distroless/base-debian11 AS build-release-stage + +WORKDIR / + +COPY --from=build-stage /docker-gs-ping /docker-gs-ping + +EXPOSE 8080 + +USER nonroot:nonroot + +ENTRYPOINT ["/docker-gs-ping"] +``` + +Since you have two Dockerfiles now, you have to tell Docker what Dockerfile +you'd like to use to build the image. Tag the new image with `multistage`. This +tag (like any other, apart from `latest`) has no special meaning for Docker, +it's just something you chose. + +```console +$ docker build -t docker-gs-ping:multistage -f Dockerfile.multistage . +``` + +Comparing the sizes of `docker-gs-ping:multistage` and `docker-gs-ping:latest` +you see a few orders-of-magnitude difference. + +```console +$ docker image ls +REPOSITORY TAG IMAGE ID CREATED SIZE +docker-gs-ping multistage e3fdde09f172 About a minute ago 28.1MB +docker-gs-ping latest 336a3f164d0f About an hour ago 1.11GB +``` + +This is so because the ["distroless"](https://github.com/GoogleContainerTools/distroless) +base image that you have used in the second stage of the build is very barebones and is designed for lean deployments of static binaries. + +There's much more to multi-stage builds, including the possibility of multi-architecture builds, +so feel free to check out [multi-stage builds](/manuals/build/building/multi-stage.md).

You are going to see some options for keeping persistent data and for wiring up the containers to talk to one another. Finally, you'll learn how to use Docker Compose to manage such multi-container local development environments effectively. + +## Local database and containers + +The database engine you are going to use is called [CockroachDB](https://www.cockroachlabs.com/product/). It is a modern, Cloud-native, distributed SQL database. + +Instead of compiling CockroachDB from the source code or using the operating system's native package manager to install CockroachDB, you are going to use the [Docker image for CockroachDB](https://hub.docker.com/r/cockroachdb/cockroach) and run it in a container. + +CockroachDB is compatible with PostgreSQL to a significant extent, and shares many conventions with the latter, particularly the default names for the environment variables. So, if you are familiar with Postgres, don't be surprised if you see some familiar environment variables names. The Go modules that work with Postgres, such as [pgx](https://pkg.go.dev/github.com/jackc/pgx), [pq](https://pkg.go.dev/github.com/lib/pq), [GORM](https://gorm.io/index.html), and [upper/db](https://upper.io/v4/) also work with CockroachDB. + +For more information on the relation between Go and CockroachDB, refer to the [CockroachDB documentation](https://www.cockroachlabs.com/docs/v20.2/build-a-go-app-with-cockroachdb.html), although this isn't necessary to continue with the present guide. + +### Storage + +The point of a database is to have a persistent store of data. [Volumes](/manuals/engine/storage/volumes.md) are the preferred mechanism for persisting data generated by and used by Docker containers. Thus, before you start CockroachDB, create the volume for it. + +To create a managed volume, run : + +```console +$ docker volume create roach +roach +``` + +You can view the list of all managed volumes in your Docker instance with the following command: + +```console +$ docker volume list +DRIVER VOLUME NAME +local roach +``` + +### Networking + +The example application and the database engine are going to talk to one another over the network. There are different kinds of network configuration possible, and you're going to use what's called a user-defined bridge network. It is going to provide you with a DNS lookup service so that you can refer to your database engine container by its hostname. + +The following command creates a new bridge network named `mynet`: + +```console +$ docker network create -d bridge mynet +51344edd6430b5acd121822cacc99f8bc39be63dd125a3b3cd517b6485ab7709 +``` + +As it was the case with the managed volumes, there is a command to list all networks set up in your Docker instance: + +```console +$ docker network list +NETWORK ID NAME DRIVER SCOPE +0ac2b1819fa4 bridge bridge local +51344edd6430 mynet bridge local +daed20bbecce host host local +6aee44f40a39 none null local +``` + +Your bridge network `mynet` has been created successfully. The other three networks, named `bridge`, `host`, and `none` are the default networks and they had been created by the Docker itself. While it's not relevant to this guide, you can learn more about Docker networking in the [networking overview](/manuals/engine/network/_index.md) section. + +### Choose good names for volumes and networks + +As the saying goes, there are only two hard things in Computer Science: cache invalidation and naming things. And off-by-one errors. + +When choosing a name for a network or a managed volume, it's best to choose a name that's indicative of the intended purpose. This guide aims for brevity, so it used short, generic names. + +### Start the database engine + +Now that the housekeeping chores are done, you can run CockroachDB in a container and attach it to the volume and network you had just created. When you run the following command, Docker will pull the image from Docker Hub and run it for you locally: + +```console +$ docker run -d \ + --name roach \ + --hostname db \ + --network mynet \ + -p 26257:26257 \ + -p 8080:8080 \ + -v roach:/cockroach/cockroach-data \ + cockroachdb/cockroach:latest-v25.4 start-single-node \ + --insecure + +# ... output omitted ... +``` + +Notice a clever use of the tag `latest-v25.4` to make sure that you're pulling the latest patch version of 25.4. The diversity of available tags depend on the image maintainer. Here, your intent was to have the latest patched version of CockroachDB while not straying too far away from the known working version as the time goes by. To see the tags available for the CockroachDB image, you can go to the [CockroachDB page on Docker Hub](https://hub.docker.com/r/cockroachdb/cockroach/tags). + +### Configure the database engine + +Now that the database engine is live, there is some configuration to do before your application can begin using it. Fortunately, it's not a lot. You must: + +1. Create a blank database. +2. Register a new user account with the database engine. +3. Grant that new user access rights to the database. + +You can do that with the help of CockroachDB built-in SQL shell. To start the SQL shell in the same container where the database engine is running, type: + +```console +$ docker exec -it roach ./cockroach sql --insecure +``` + +1. In the SQL shell, create the database that the example application is going to use: + + ```sql + CREATE DATABASE mydb; + ``` + +2. Register a new SQL user account with the database engine. Use the username `totoro`. + + ```sql + CREATE USER totoro; + ``` + +3. Give the new user the necessary permissions: + + ```sql + GRANT ALL ON DATABASE mydb TO totoro; + ``` + +4. Type `quit` to exit the shell. + +The following is an example of interaction with the SQL shell. + +```console +$ sudo docker exec -it roach ./cockroach sql --insecure +# +# Welcome to the CockroachDB SQL shell. +# All statements must be terminated by a semicolon. +# To exit, type: \q. +# +# Server version: CockroachDB CCL v20.1.15 (x86_64-unknown-linux-gnu, built 2021/04/26 16:11:58, go1.13.9) (same version as client) +# Cluster ID: 7f43a490-ccd6-4c2a-9534-21f393ca80ce +# +# Enter \? for a brief introduction. +# +root@:26257/defaultdb> CREATE DATABASE mydb; +CREATE DATABASE + +Time: 22.985478ms + +root@:26257/defaultdb> CREATE USER totoro; +CREATE ROLE + +Time: 13.921659ms + +root@:26257/defaultdb> GRANT ALL ON DATABASE mydb TO totoro; +GRANT + +Time: 14.217559ms + +root@:26257/defaultdb> quit +oliver@hki:~$ +``` + +### Meet the example application + +Now that you have started and configured the database engine, you can switch your attention to the application. + +The example application for this module is an extended version of `docker-gs-ping` application you've used in the previous modules. You have two options: + +- You can update your local copy of `docker-gs-ping` to match the new extended version presented in this chapter; or +- You can clone the [docker/docker-gs-ping-dev](https://github.com/docker/docker-gs-ping-dev) repository. This latter approach is recommended. + +To checkout the example application, run: + +```console +$ git clone https://github.com/docker/docker-gs-ping-dev.git +# ... output omitted ... +``` + +The application's `main.go` now includes database initialization code, as well as the code to implement a new business requirement: + +- An HTTP `POST` request to `/send` containing a `{ "value" : string }` JSON must save the value to the database. + +You also have an update for another business requirement. The requirement was: + +- The application responds with a text message containing a heart symbol ("`<3`") on requests to `/`. + +And now it's going to be: + +- The application responds with the string containing the count of messages stored in the database, enclosed in the parentheses. + + Example output: `Hello, Docker! (7)` + +The full source code listing of `main.go` follows. + +```go +package main + +import ( + "context" + "database/sql" + "fmt" + "log" + "net/http" + "os" + + "github.com/cenkalti/backoff/v4" + "github.com/cockroachdb/cockroach-go/v2/crdb" + "github.com/labstack/echo/v4" + "github.com/labstack/echo/v4/middleware" +) + +func main() { + + e := echo.New() + + e.Use(middleware.Logger()) + e.Use(middleware.Recover()) + + db, err := initStore() + if err != nil { + log.Fatalf("failed to initialize the store: %s", err) + } + defer db.Close() + + e.GET("/", func(c echo.Context) error { + return rootHandler(db, c) + }) + + e.GET("/ping", func(c echo.Context) error { + return c.JSON(http.StatusOK, struct{ Status string }{Status: "OK"}) + }) + + e.POST("/send", func(c echo.Context) error { + return sendHandler(db, c) + }) + + httpPort := os.Getenv("HTTP_PORT") + if httpPort == "" { + httpPort = "8080" + } + + e.Logger.Fatal(e.Start(":" + httpPort)) +} + +type Message struct { + Value string `json:"value"` +} + +func initStore() (*sql.DB, error) { + + pgConnString := fmt.Sprintf("host=%s port=%s dbname=%s user=%s password=%s sslmode=disable", + os.Getenv("PGHOST"), + os.Getenv("PGPORT"), + os.Getenv("PGDATABASE"), + os.Getenv("PGUSER"), + os.Getenv("PGPASSWORD"), + ) + + var ( + db *sql.DB + err error + ) + openDB := func() error { + db, err = sql.Open("postgres", pgConnString) + return err + } + + err = backoff.Retry(openDB, backoff.NewExponentialBackOff()) + if err != nil { + return nil, err + } + + if _, err := db.Exec( + "CREATE TABLE IF NOT EXISTS message (value TEXT PRIMARY KEY)"); err != nil { + return nil, err + } + + return db, nil +} + +func rootHandler(db *sql.DB, c echo.Context) error { + r, err := countRecords(db) + if err != nil { + return c.HTML(http.StatusInternalServerError, err.Error()) + } + return c.HTML(http.StatusOK, fmt.Sprintf("Hello, Docker!

It uses the official Docker Go image to build the application and then builds the final image by placing the compiled binary into the much slimmer, distroless image. + +Regardless of whether you had updated the old example application, or checked out the new one, this new Docker image has to be built to reflect the changes to the application source code. + +### Build the application + +You can build the image with the familiar `build` command: + +```console +$ docker build --tag docker-gs-ping-roach . +``` + +### Run the application + +Now, run your container. This time you'll need to set some environment variables so that your application knows how to access the database. For now, you’ll do this right in the `docker run` command. Later you'll see a more convenient method with Docker Compose. + +> [!NOTE] +> +> Since you're running your CockroachDB cluster in insecure mode, the value for the password can be anything. +> +> In production, don't run in insecure mode. + +```console +$ docker run -it --rm -d \ + --network mynet \ + --name rest-server \ + -p 80:8080 \ + -e PGUSER=totoro \ + -e PGPASSWORD=myfriend \ + -e PGHOST=db \ + -e PGPORT=26257 \ + -e PGDATABASE=mydb \ + docker-gs-ping-roach +``` + +There are a few points to note about this command. + +- You map container port `8080` to host port `80` this time. Thus, for `GET` requests you can get away with literally `curl localhost`: + + ```console + $ curl localhost + Hello, Docker! (0) + ``` + + Or, if you prefer, a proper URL would work just as well: + + ```console + $ curl http://localhost/ + Hello, Docker! (0) + ``` + +- The total number of stored messages is `0` for now. This is fine, because you haven't posted anything to your application yet. +- You refer to the database container by its hostname, which is `db`. This is why you had `--hostname db` when you started the database container. + +- The actual password doesn't matter, but it must be set to something to avoid confusing the example application. +- The container you've just run is named `rest-server`. These names are useful for managing the container lifecycle: + + ```console + # Don't do this just yet, it's only an example: + $ docker container rm --force rest-server + ``` + +### Test the application + +In the previous section, you've already tested querying your application with `GET` and it returned zero for the stored message counter. Now, post some messages to it: + +```console +$ curl --request POST \ + --url http://localhost/send \ + --header 'content-type: application/json' \ + --data '{"value": "Hello, Docker!"}' +``` + +The application responds with the contents of the message, which means it has been saved in the database: + +```json +{ "value": "Hello, Docker!" } +``` + +Send another message: + +```console +$ curl --request POST \ + --url http://localhost/send \ + --header 'content-type: application/json' \ + --data '{"value": "Hello, Oliver!"}' +``` + +And again, you get the value of the message back: + +```json +{ "value": "Hello, Oliver!" } +``` + +Run curl and see what the message counter says: + +```console +$ curl localhost +Hello, Docker! (2) +``` + +In this example, you sent two messages and the database kept them. Or has it? Stop and remove all your containers, but not the volumes, and try again. + +First, stop the containers: + +```console +$ docker container stop rest-server roach +rest-server +roach +``` + +Then, remove them: + +```console +$ docker container rm rest-server roach +rest-server +roach +``` + +Verify that they're gone: + +```console +$ docker container list --all +CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES +``` + +And start them again, database first: + +```console +$ docker run -d \ + --name roach \ + --hostname db \ + --network mynet \ + -p 26257:26257 \ + -p 8080:8080 \ + -v roach:/cockroach/cockroach-data \ + cockroachdb/cockroach:latest-v25.4 start-single-node \ + --insecure +``` + +And the service next: + +```console +$ docker run -it --rm -d \ + --network mynet \ + --name rest-server \ + -p 80:8080 \ + -e PGUSER=totoro \ + -e PGPASSWORD=myfriend \ + -e PGHOST=db \ + -e PGPORT=26257 \ + -e PGDATABASE=mydb \ + docker-gs-ping-roach +``` + +Lastly, query your service: + +```console +$ curl localhost +Hello, Docker! (2) +``` + +Great! The count of records from the database is correct although you haven't only stopped the containers, but you've also removed them before starting new instances. The difference is in the managed volume for CockroachDB, which you reused. The new CockroachDB container has read the database files from the disk, just as it normally would if it were running outside the container. + +### Wind down everything + +Remember, that you're running CockroachDB in insecure mode. Now that you've built and tested your application, it's time to wind everything down before moving on. You can list the containers that you are running with the `list` command: + +```console +$ docker container list +``` + +Now that you know the container IDs, you can use `docker container stop` and `docker container rm`, as demonstrated in the previous modules. + +Stop the CockroachDB and `docker-gs-ping-roach` containers before moving on. + +## Better productivity with Docker Compose + +At this point, you might be wondering if there is a way to avoid having to deal with long lists of arguments to the `docker` command. The toy example you used in this series requires five environment variables to define the connection to the database. A real application might need many, many more. Then there is also a question of dependencies. Ideally, you want to make sure that the database is started before your application is run. And spinning up the database instance may require another Docker command with many options. But there is a better way to orchestrate these deployments for local development purposes. + +In this section, you'll create a Docker Compose file to start your `docker-gs-ping-roach` application and CockroachDB database engine with a single command. + +### Configure Docker Compose + +In your application's directory, create a new text file named `compose.yaml` with the following content. + +```yaml +version: "3.8" + +services: + docker-gs-ping-roach: + depends_on: + - roach + build: + context: . + container_name: rest-server + hostname: rest-server + networks: + - mynet + ports: + - 80:8080 + environment: + - PGUSER=${PGUSER:-totoro} + - PGPASSWORD=${PGPASSWORD:?database password not set} + - PGHOST=${PGHOST:-db} + - PGPORT=${PGPORT:-26257} + - PGDATABASE=${PGDATABASE:-mydb} + deploy: + restart_policy: + condition: on-failure + roach: + image: cockroachdb/cockroach:latest-v25.4 + container_name: roach + hostname: db + networks: + - mynet + ports: + - 26257:26257 + - 8080:8080 + volumes: + - roach:/cockroach/cockroach-data + command: start-single-node --insecure + +volumes: + roach: + +networks: + mynet: + driver: bridge +``` + +This Docker Compose configuration is super convenient as you don't have to type all the parameters to pass to the `docker run` command. You can declaratively do that in the Docker Compose file. The [Docker Compose documentation pages](/manuals/compose/_index.md) are quite extensive and include a full reference for the Docker Compose file format. + +### The `.env` file + +Docker Compose will automatically read environment variables from a `.env` file if it's available. Since your Compose file requires `PGPASSWORD` to be set, add the following content to the `.env` file: + +```bash +PGPASSWORD=whatever +``` + +The exact value doesn't really matter for this example, because you run CockroachDB in insecure mode. Make sure you set the variable to some value to avoid getting an error. + +### Merging Compose files + +The file name `compose.yaml` is the default file name which `docker compose` command recognizes if no `-f` flag is provided. This means you can have multiple Docker Compose files if your environment has such requirements. Furthermore, Docker Compose files are... composable (pun intended), so multiple files can be specified on the command line to merge parts of the configuration together. The following list is just a few examples of scenarios where such a feature would be very useful: + +- Using a bind mount for the source code for local development but not when running the CI tests; +- Switching between using a pre-built image for the frontend for some API application vs creating a bind mount for source code; +- Adding additional services for integration testing; +- And many more... + +You aren't going to cover any of these advanced use cases here. + +### Variable substitution in Docker Compose + +One of the really cool features of Docker Compose is [variable substitution](/reference/compose-file/interpolation.md). You can see some examples in the Compose file, `environment` section. By means of an example: + +- `PGUSER=${PGUSER:-totoro}` means that inside the container, the environment variable `PGUSER` shall be set to the same value as it has on the host machine where Docker Compose is run. If there is no environment variable with this name on the host machine, the variable inside the container gets the default value of `totoro`. +- `PGPASSWORD=${PGPASSWORD:?database password not set}` means that if the environment variable `PGPASSWORD` isn't set on the host, Docker Compose will display an error. This is OK, because you don't want to hard-code default values for the password. You set the password value in the `.env` file, which is local to your machine. It is always a good idea to add `.env` to `.gitignore` to prevent the secrets being checked into the version control. + +Other ways of dealing with undefined or empty values exist, as documented in the [variable substitution](/reference/compose-file/interpolation.md) section of the Docker documentation. + +### Validating Docker Compose configuration + +Before you apply changes made to a Compose configuration file, there is an opportunity to validate the content of the configuration file with the following command: + +```console +$ docker compose config +``` + +When this command is run, Docker Compose reads the file `compose.yaml`, parses it into a data structure in memory, validates where possible, and prints back the reconstruction of that configuration file from its internal representation. If this isn't possible due to errors, Docker prints an error message instead. + +### Build and run the application using Docker Compose + +Start your application and confirm that it's running. + +```console +$ docker compose up --build +``` + +You passed the `--build` flag so Docker will compile your image and then start it. + +> [!NOTE] +> +> Docker Compose is a useful tool, but it has its own quirks. For example, no rebuild is triggered on the update to the source code unless the `--build` flag is provided. It is a very common pitfall to edit one's source code, and forget to use the `--build` flag when running `docker compose up`. + +Since your set-up is now run by Docker Compose, it has assigned it a project name, so you get a new volume for your CockroachDB instance. This means that your application will fail to connect to the database, because the database doesn't exist in this new volume. The terminal displays an authentication error for the database: + +```text +# ... omitted output ... +rest-server | 2021/05/10 00:54:25 failed to initialise the store: pq: password authentication failed for user totoro +roach | * +roach | * INFO: Replication was disabled for this cluster. +roach | * When/if adding nodes in the future, update zone configurations to increase the replication factor. +roach | * +roach | CockroachDB node starting at 2021-05-10 00:54:26.398177 +0000 UTC (took 3.0s) +roach | build: CCL v20.1.15 @ 2021/04/26 16:11:58 (go1.13.9) +roach | webui: http://db:8080 +roach | sql: postgresql://root@db:26257?sslmode=disable +roach | RPC client flags: /cockroach/cockroach --host=db:26257 --insecure +roach | logs: /cockroach/cockroach-data/logs +roach | temp dir: /cockroach/cockroach-data/cockroach-temp349434348 +roach | external I/O path: /cockroach/cockroach-data/extern +roach | store[0]: path=/cockroach/cockroach-data +roach | storage engine: rocksdb +roach | status: initialized new cluster +roach | clusterID: b7b1cb93-558f-4058-b77e-8a4ddb329a88 +roach | nodeID: 1 +rest-server exited with code 0 +rest-server | 2021/05/10 00:54:25 failed to initialise the store: pq: password authentication failed for user totoro +rest-server | 2021/05/10 00:54:26 failed to initialise the store: pq: password authentication failed for user totoro +rest-server | 2021/05/10 00:54:29 failed to initialise the store: pq: password authentication failed for user totoro +rest-server | 2021/05/10 00:54:25 failed to initialise the store: pq: password authentication failed for user totoro +rest-server | 2021/05/10 00:54:26 failed to initialise the store: pq: password authentication failed for user totoro +rest-server | 2021/05/10 00:54:29 failed to initialise the store: pq: password authentication failed for user totoro +rest-server exited with code 1 +# ... omitted output ... +``` + +Because of the way you set up your deployment using `restart_policy`, the failing container is being restarted every 20 seconds. So, in order to fix the problem, you need to log in to the database engine and create the user. You've done it before in [Configure the database engine](#configure-the-database-engine). + +This isn't a big deal. All you have to do is to connect to CockroachDB instance and run the three SQL commands to create the database and the user, as described in [Configure the database engine](#configure-the-database-engine). + +So, log in to the database engine from another terminal: + +```console +$ docker exec -it roach ./cockroach sql --insecure +``` + +And run the same commands as before to create the database `mydb`, the user `totoro`, and to grant that user necessary permissions. Once you do that (and the example application container is automatically restarts), the `rest-service` stops failing and restarting and the console goes quiet. + +It would have been possible to connect the volume that you had previously used, but for the purposes of this example it's more trouble than it's worth and it also provided an opportunity to show how to introduce resilience into your deployment via the `restart_policy` Compose file feature. + +### Testing the application + +Now, test your API endpoint. In the new terminal, run the following command: + +```console +$ curl http://localhost/ +``` + +You should receive the following response: + +```json +Hello, Docker! (0) +``` + +### Shutting down + +To stop the containers started by Docker Compose, press `ctrl+c` in the terminal where you ran `docker compose up`. To remove those containers after they've been stopped, run `docker compose down`. + +### Detached mode + +You can run containers started by the `docker compose` command in detached mode, just as you would with the `docker` command, by using the `-d` flag. + +To start the stack, defined by the Compose file in detached mode, run: + +```console +$ docker compose up --build -d +``` + +Then, you can use `docker compose stop` to stop the containers and `docker compose down` to remove them. + +## Further exploration + +You can run `docker compose` to see what other commands are available. + +## Wrap up + +There are some tangential, yet interesting points that were purposefully not covered in this chapter. For the more adventurous reader, this section offers some pointers for further study. + +### Persistent storage + +A managed volume isn't the only way to provide your container with persistent storage. It is highly recommended to get acquainted with available storage options and their use cases, covered in [Manage data in Docker](/manuals/engine/storage/_index.md). + +### CockroachDB clusters + +You ran a single instance of CockroachDB, which was enough for this example. But, it's possible to run a CockroachDB cluster, which is made of multiple instances of CockroachDB, each instance running in its own container. Since CockroachDB engine is distributed by design, it would have taken surprisingly little change to your procedure to run a cluster with multiple nodes. + +Such distributed set-up offers interesting possibilities, such as applying Chaos Engineering techniques to simulate parts of the cluster failing and evaluating your application's ability to cope with such failures. + +If you are interested in experimenting with CockroachDB clusters, check out: + +- [Start a CockroachDB Cluster in Docker](https://www.cockroachlabs.com/docs/v20.2/start-a-local-cluster-in-docker-mac.html) article; and +- Documentation for Docker Compose keywords [`deploy`](/reference/compose-file/legacy-versions.md) and [`replicas`](/reference/compose-file/legacy-versions.md). + +### Other databases + +Since you didn't run a cluster of CockroachDB instances, you might be wondering whether you could have used a non-distributed database engine. The answer is 'yes', and if you were to pick a more traditional SQL database, such as [PostgreSQL](https://www.postgresql.org/), the process described in this chapter would have been very similar. + +## Next steps + +In this module, you set up a containerized development environment with your application and the database engine running in different containers. You also wrote a Docker Compose file which links the two containers together and provides for easy starting up and tearing down of the development environment. + +In the next module, you'll take a look at one possible approach to running functional tests in Docker. diff --git a/content/guides/golang/run-containers.md b/content/guides/golang/run-containers.md new file mode 100644 index 000000000000..34e87c648915 --- /dev/null +++ b/content/guides/golang/run-containers.md @@ -0,0 +1,210 @@ +--- +title: Run your Go image as a container +linkTitle: Run containers +weight: 10 +keywords: get started, go, golang, run, container +description: Learn how to run the image as a container. +aliases: + - /get-started/golang/run-containers/ + - /language/golang/run-containers/ + - /guides/language/golang/run-containers/ +--- + +## Prerequisites + +Work through the steps to containerize a Go application in [Build your Go image](build-images.md). + +## Overview + +In the previous module you created a `Dockerfile` for your example application and then you created your Docker image using the command `docker build`. Now that you have the image, you can run that image and see if your application is running correctly. + +A container is a normal operating system process except that this process is isolated and has its own file system, its own networking, and its own isolated process tree separate from the host. + +To run an image inside of a container, you use the `docker run` command. It requires one parameter and that's the image name. Start your image and make sure it's running correctly. Run the following command in your terminal. + +```console +$ docker run docker-gs-ping +``` + +```text + ____ __ + / __/___/ / ___ + / _// __/ _ \/ _ \ +/___/\__/_//_/\___/ v4.10.2 +High performance, minimalist Go web framework +https://echo.labstack.com +____________________________________O/_______ + O\ +⇨ http server started on [::]:8080 +``` + +When you run this command, you’ll notice that you weren't returned to the command prompt. This is because your application is a REST server and will run in a loop waiting for incoming requests without returning control back to the OS until you stop the container. + +Make a GET request to the server using the curl command. + +```console +$ curl http://localhost:8080/ +curl: (7) Failed to connect to localhost port 8080: Connection refused +``` + +Your curl command failed because the connection to your server was refused. +Meaning that you weren't able to connect to localhost on port 8080. This is +expected because your container is running in isolation which includes +networking. Stop the container and restart with port 8080 published on your +local network. + +To stop the container, press ctrl-c. This will return you to the terminal prompt. + +To publish a port for your container, you’ll use the `--publish` flag (`-p` for short) on the `docker run` command. The format of the `--publish` command is `[host_port]:[container_port]`. So if you wanted to expose port `8080` inside the container to port `3000` outside the container, you would pass `3000:8080` to the `--publish` flag. + +Start the container and expose port `8080` to port `8080` on the host. + +```console +$ docker run --publish 8080:8080 docker-gs-ping +``` + +Now, rerun the curl command. + +```console +$ curl http://localhost:8080/ +Hello, Docker! <3 +``` + +Success! You were able to connect to the application running inside of your container on port 8080. Switch back to the terminal where your container is running and you should see the `GET` request logged to the console. + +Press `ctrl-c` to stop the container. + +## Run in detached mode + +This is great so far, but your sample application is a web server and you +shouldn't have to have your terminal connected to the container. Docker can run +your container in detached mode in the background. To do this, you can use the +`--detach` or `-d` for short. Docker will start your container the same as +before but this time will detach from the container and return you to the +terminal prompt. + +```console +$ docker run -d -p 8080:8080 docker-gs-ping +d75e61fcad1e0c0eca69a3f767be6ba28a66625ce4dc42201a8a323e8313c14e +``` + +Docker started your container in the background and printed the container ID on the terminal. + +Again, make sure that your container is running. Run the same `curl` command: + +```console +$ curl http://localhost:8080/ +Hello, Docker! <3 +``` + +## List containers + +Since you ran your container in the background, how do you know if your container is running or what other containers are running on your machine? Well, to see a list of containers running on your machine, run `docker ps`. This is similar to how the ps command is used to see a list of processes on a Linux machine. + +```console +$ docker ps + +CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES +d75e61fcad1e docker-gs-ping "/docker-gs-ping" 41 seconds ago Up 40 seconds 0.0.0.0:8080->8080/tcp inspiring_ishizaka +``` + +The `ps` command tells you a bunch of stuff about your running containers. You can see the container ID, the image running inside the container, the command that was used to start the container, when it was created, the status, ports that are exposed, and the names of the container. + +You are probably wondering where the name of your container is coming from. Since you didn’t provide a name for the container when you started it, Docker generated a random name. You'll fix this in a minute but first you need to stop the container. To stop the container, run the `docker stop` command, passing the container's name or ID. + +```console +$ docker stop inspiring_ishizaka +inspiring_ishizaka +``` + +Now rerun the `docker ps` command to see a list of running containers. + +```console +$ docker ps + +CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES +``` + +## Stop, start, and name containers + +Docker containers can be started, stopped and restarted. When you stop a container, it's not removed but the status is changed to stopped and the process inside of the container is stopped. When you ran the `docker ps` command, the default output is to only show running containers. If you pass the `--all` or `-a` for short, you will see all containers on your system, including stopped containers and running containers. + +```console +$ docker ps --all + +CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES +d75e61fcad1e docker-gs-ping "/docker-gs-ping" About a minute ago Exited (2) 23 seconds ago inspiring_ishizaka +f65dbbb9a548 docker-gs-ping "/docker-gs-ping" 3 minutes ago Exited (2) 2 minutes ago wizardly_joliot +aade1bf3d330 docker-gs-ping "/docker-gs-ping" 3 minutes ago Exited (2) 3 minutes ago magical_carson +52d5ce3c15f0 docker-gs-ping "/docker-gs-ping" 9 minutes ago Exited (2) 3 minutes ago gifted_mestorf +``` + +If you’ve been following along, you should see several containers listed. These are containers that you started and stopped but haven't removed yet. + +Restart the container that you have just stopped. Locate the name of the container and replace the name of the container in the following `restart` command: + +```console +$ docker restart inspiring_ishizaka +``` + +Now, list all the containers again using the `ps` command: + +```console +$ docker ps -a + +CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES +d75e61fcad1e docker-gs-ping "/docker-gs-ping" 2 minutes ago Up 5 seconds 0.0.0.0:8080->8080/tcp inspiring_ishizaka +f65dbbb9a548 docker-gs-ping "/docker-gs-ping" 4 minutes ago Exited (2) 2 minutes ago wizardly_joliot +aade1bf3d330 docker-gs-ping "/docker-gs-ping" 4 minutes ago Exited (2) 4 minutes ago magical_carson +52d5ce3c15f0 docker-gs-ping "/docker-gs-ping" 10 minutes ago Exited (2) 4 minutes ago gifted_mestorf +``` + +Notice that the container you just restarted has been started in detached mode and has port `8080` exposed. Also, note that the status of the container is `Up X seconds`. When you restart a container, it will be started with the same flags or commands that it was originally started with. + +Stop and remove all of your containers and take a look at fixing the random naming issue. + +Stop the container you just started. Find the name of your running container and replace the name in the following command with the name of the container on your system: + +```console +$ docker stop inspiring_ishizaka +inspiring_ishizaka +``` + +Now that all of your containers are stopped, remove them. When a container is removed, it's no longer running nor is it in the stopped state. Instead, the process inside the container is terminated and the metadata for the container is removed. + +To remove a container, run the `docker rm` command passing the container name. You can pass multiple container names to the command in one command. + +Again, make sure you replace the containers names in the following command with the container names from your system: + +```console +$ docker rm inspiring_ishizaka wizardly_joliot magical_carson gifted_mestorf + +inspiring_ishizaka +wizardly_joliot +magical_carson +gifted_mestorf +``` + +Run the `docker ps --all` command again to verify that all containers are gone. + +Now, address the pesky random name issue. Standard practice is to name your containers for the simple reason that it's easier to identify what's running in the container and what application or service it's associated with. Just like good naming conventions for variables in your code makes it simpler to read. So goes naming your containers. + +To name a container, you must pass the `--name` flag to the `run` command: + +```console +$ docker run -d -p 8080:8080 --name rest-server docker-gs-ping +3bbc6a3102ea368c8b966e1878a5ea9b1fc61187afaac1276c41db22e4b7f48f +``` + +```console +$ docker ps + +CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES +3bbc6a3102ea docker-gs-ping "/docker-gs-ping" 25 seconds ago Up 24 seconds 0.0.0.0:8080->8080/tcp rest-server +``` + +Now, you can easily identify your container based on the name. + +## Next steps + +In this module, you learned how to run containers and publish ports. You also learned to manage the lifecycle of containers. You then learned the importance of naming your containers so that they're more easily identifiable. In the next module, you’ll learn how to run a database in a container and connect it to your application. diff --git a/content/guides/golang/run-tests.md b/content/guides/golang/run-tests.md new file mode 100644 index 000000000000..b4b435fd62e2 --- /dev/null +++ b/content/guides/golang/run-tests.md @@ -0,0 +1,96 @@ +--- +title: Run your tests using Go test +linkTitle: Run your tests +weight: 30 +keywords: build, go, golang, test +description: How to build and run your Go tests in a container +aliases: + - /get-started/golang/run-tests/ + - /language/golang/run-tests/ + - /guides/language/golang/run-tests/ +--- + +## Prerequisites + +Complete the [Build your Go image](build-images.md) section of this guide. + +## Overview + +Testing is an essential part of modern software development.

Once connected, this sample app will log messages it consumes from the `demo` topic. Additionally, when it runs in development mode, it will also create the topic if it isn’t found. + +1. If you don’t have the Kafka cluster running from the previous step, run the following command to start a Kafka instance: + + ```console + $ docker run -d --name=kafka -p 9092:9092 apache/kafka + ``` + +2. Clone the [GitHub repository](https://github.com/dockersamples/kafka-development-node) locally. + + ```console + $ git clone https://github.com/dockersamples/kafka-development-node.git + ``` + +3. Navigate into the project. + + ```console + cd kafka-development-node/app + ``` + +4. Install the dependencies using yarn. + + ```console + $ yarn install + ``` + +5. Start the application using `yarn dev`. This will set the `NODE_ENV` environment variable to `development` and use `nodemon` to watch for file changes. + + ```console + $ yarn dev + ``` + +6.

To do so, you will now run the application out of a container instead of natively. + +But before you do that, it’s important to understand how Kafka listeners work and how those listeners help clients connect. + +### Understanding Kafka listeners + +When a client connects to a Kafka cluster, it actually connects to a “broker”. While brokers have many roles, one of them is to support load balancing of clients. When a client connects, the broker returns a set of connection URLs the client should then use for the client to connect for the producing or consuming of messages. How are these connection URLs configured? + +Each Kafka instance has a set of listeners and advertised listeners. The “listeners” are what Kafka binds to and the “advertised listeners” configure how clients should connect to the cluster. The connection URLs a client receives is based on which listener a client connects to. + +### Defining the listeners + +To help this make sense, let’s look at how Kafka needs to be configured to support two connection opportunities: + +1. Host connections (those coming through the host’s mapped port) - these will need to connect using localhost +2. Docker connections (those coming from inside the Docker networks) - these can not connect using localhost, but the network alias (or DNS address) of the Kafka service + +Since there are two different methods clients need to connect, two different listeners are required - `HOST` and `DOCKER`. The `HOST` listener will tell clients to connect using localhost:9092, while the `DOCKER` listener will inform clients to connect using `kafka:9093`. Notice this means Kafka is listening on both ports 9092 and 9093. But, only the host listener needs to be exposed to the host. + +![Diagram showing the DOCKER and HOST listeners and how they are exposed to the host and Docker networks](./images/kafka-1.webp) + +In order to set this up, the `compose.yaml` for Kafka needs some additional configuration. Once you start overriding some of the defaults, you also need to specify a few other options in order for KRaft mode to work. + +```yaml +services: + kafka: + image: apache/kafka-native + ports: + - "9092:9092" + environment: + # Configure listeners for both docker and host communication + KAFKA_LISTENERS: CONTROLLER://localhost:9091,HOST://0.0.0.0:9092,DOCKER://0.0.0.0:9093 + KAFKA_ADVERTISED_LISTENERS: HOST://localhost:9092,DOCKER://kafka:9093 + KAFKA_LISTENER_SECURITY_PROTOCOL_MAP: CONTROLLER:PLAINTEXT,DOCKER:PLAINTEXT,HOST:PLAINTEXT + + # Settings required for KRaft mode + KAFKA_NODE_ID: 1 + KAFKA_PROCESS_ROLES: broker,controller + KAFKA_CONTROLLER_LISTENER_NAMES: CONTROLLER + KAFKA_CONTROLLER_QUORUM_VOTERS: 1@localhost:9091 + + # Listener to use for broker-to-broker communication + KAFKA_INTER_BROKER_LISTENER_NAME: DOCKER + + # Required for a single node cluster + KAFKA_OFFSETS_TOPIC_REPLICATION_FACTOR: 1 +``` + +Give it a try using the steps below. + +1. If you have the Node app running from the previous step, go ahead and stop it by pressing `ctrl+c` in the terminal. + +2. If you have the Kafka cluster running from the previous section, go ahead and stop that container using the following command: + + ```console + $ docker rm -f kafka + ``` + +3. Start the Compose stack by running the following command at the root of the cloned project directory: + + ```console + $ docker compose up + ``` + + After a moment, the application will be up and running. + +4. In the stack is another service that can be used to publish messages. Open it by going to [http://localhost:3000](http://localhost:3000). As you type in a message and submit the form, you should see the log message of the message being received by the app. + + This helps demonstrate how a containerized approach makes it easy to add additional services to help test and troubleshoot your application. + +## Adding cluster visualization + +Once you start using containers in your development environment, you start to realize the ease of adding additional services that are solely focused on helping development, such as visualizers and other supporting services. Since you have Kafka running, it might be helpful to visualize what’s going on in the Kafka cluster. To do so, you can run the [Kafbat UI web application](https://github.com/kafbat/kafka-ui). + +To add it to your own project (it’s already in the demo application), you only need to add the following configuration to your Compose file: + +```yaml +services: + kafka-ui: + image: kafbat/kafka-ui:main + ports: + - 8080:8080 + environment: + DYNAMIC_CONFIG_ENABLED: "true" + KAFKA_CLUSTERS_0_NAME: local + KAFKA_CLUSTERS_0_BOOTSTRAPSERVERS: kafka:9093 + depends_on: + - kafka +``` + +Then, once the Compose stack starts, you can open your browser to [http://localhost:8080](http://localhost:8080) and navigate around to view additional details about the cluster, check on consumers, publish test messages, and more. + +## Testing with Kafka + +If you’re interested in learning how you can integrate Kafka easily into your integration tests, check out the [Testing Spring Boot Kafka Listener using Testcontainers guide](https://testcontainers.com/guides/testing-spring-boot-kafka-listener-using-testcontainers/).

Place the following in a file called `bb.yaml`: + +```yaml +apiVersion: apps/v1 +kind: Deployment +metadata: + name: bb-demo + namespace: default +spec: + replicas: 1 + selector: + matchLabels: + bb: web + template: + metadata: + labels: + bb: web + spec: + containers: + - name: bb-site + image: getting-started + imagePullPolicy: Never +--- +apiVersion: v1 +kind: Service +metadata: + name: bb-entrypoint + namespace: default +spec: + type: NodePort + selector: + bb: web + ports: + - port: 3000 + targetPort: 3000 + nodePort: 30001 +``` + +In this Kubernetes YAML file, there are two objects, separated by the `---`: + +- A `Deployment`, describing a scalable group of identical pods. In this case, you'll get just one `replica`, or copy of your pod, and that pod (which is described under the `template:` key) has just one container in it, based off of your `getting-started` image from the previous step in this tutorial. +- A `NodePort` service, which will route traffic from port 30001 on your host to port 3000 inside the pods it routes to, allowing you to reach your Todo app from the network. + +Also, notice that while Kubernetes YAML can appear long and complicated at first, it almost always follows the same pattern: + +- The `apiVersion`, which indicates the Kubernetes API that parses this object +- The `kind` indicating what sort of object this is +- Some `metadata` applying things like names to your objects +- The `spec` specifying all the parameters and configurations of your object. + +## Deploy and check your application + +1. In a terminal, navigate to where you created `bb.yaml` and deploy your application to Kubernetes: + + ```console + $ kubectl apply -f bb.yaml + ``` + + You should see output that looks like the following, indicating your Kubernetes objects were created successfully: + + ```shell + deployment.apps/bb-demo created + service/bb-entrypoint created + ``` + +2. Make sure everything worked by listing your deployments: + + ```console + $ kubectl get deployments + ``` + + if all is well, your deployment should be listed as follows: + + ```shell + NAME READY UP-TO-DATE AVAILABLE AGE + bb-demo 1/1 1 1 40s + ``` + + This indicates all one of the pods you asked for in your YAML are up and running. Do the same check for your services: + + ```console + $ kubectl get services + + NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE + bb-entrypoint NodePort 10.106.145.116 3000:30001/TCP 53s + kubernetes ClusterIP 10.96.0.1 443/TCP 138d + ``` + + In addition to the default `kubernetes` service, we see our `bb-entrypoint` service, accepting traffic on port 30001/TCP. + +3. Open a browser and visit your Todo app at `localhost:30001`. You should see your Todo application, the same as when you ran it as a stand-alone container in [Part 2](02_our_app.md) of the tutorial. + +4. Once satisfied, tear down your application: + + ```console + $ kubectl delete -f bb.yaml + ``` + +## Conclusion + +At this point, you have successfully used Docker Desktop to deploy your application to a fully-featured Kubernetes environment on your development machine. You can now add other components to your app and taking advantage of all the features and power of Kubernetes, right on your own machine. + +In addition to deploying to Kubernetes, you have also described your application as a Kubernetes YAML file.

Connect to Postgres from the local system. + + The `psql` is the PostgreSQL interactive shell that is used to connect to a Postgres database and let you start executing SQL commands.

In this demonstration, you'll first create a script that holds SQL commands. The script defines the database, and table structure and inserts sample data. Then you will connect the database to verify the data. + +Assuming that you have an existing Postgres database instance up and running, follow these steps to seed the database. + +1. Create an empty file named `seed.sql` and add the following content. + + ```sql + CREATE DATABASE sampledb; + + \c sampledb + + CREATE TABLE users ( + id SERIAL PRIMARY KEY, + name VARCHAR(50), + email VARCHAR(100) UNIQUE + ); + + INSERT INTO users (name, email) VALUES + ('Alpha', 'alpha@example.com'), + ('Beta', 'beta@example.com'), + ('Gamma', 'gamma@example.com'); + ``` + + The SQL script creates a new database called `sampledb`, connects to it, and creates a `users` table. The table includes an auto-incrementing `id` as the primary key, a `name` field with a maximum length of 50 characters, and a unique `email` field with up to 100 characters. + + After creating the table, the `INSERT` command inserts three users into the `users` table with their respective names and emails. This setup forms a basic database structure to store user information with unique email addresses. + +2. Seed the database. + + It’s time to feed the content of the `seed.sql` directly into the database by using the `<` operator. The command is used to execute a SQL script named `seed.sql` against a Postgres database named `sampledb`. + + ```console + $ cat seed.sql | docker exec -i postgres psql -h localhost -U postgres -f- + ``` + + Once the query is executed, you will see the following results: + + ```plaintext + CREATE DATABASE + You are now connected to database "sampledb" as user "postgres". + CREATE TABLE + INSERT 0 3 + ``` + +3. Run the following `psql` command to verify if the table named users is populated in the database `sampledb` or not. + + ```console + $ docker exec -it postgres psql -h localhost -U postgres sampledb + ``` + + You can now run `\l` in the `psql` shell to list all the databases on the Postgres server. + + ```console + sampledb=# \l + List of databases + Name | Owner | Encoding | Collate | Ctype | ICU Locale | Locale Provider | Access privileges + -----------+----------+----------+------------+------------+------------+-----------------+----------------------- + postgres | postgres | UTF8 | en_US.utf8 | en_US.utf8 | | libc | + sampledb | postgres | UTF8 | en_US.utf8 | en_US.utf8 | | libc | + template0 | postgres | UTF8 | en_US.utf8 | en_US.utf8 | | libc | =c/postgres + + | | | | | | | postgres=CTc/postgres + template1 | postgres | UTF8 | en_US.utf8 | en_US.utf8 | | libc | =c/postgres + + | | | | | | | postgres=CTc/postgres + (4 rows) + ``` + + To retrieve all the data from the users table, enter the following query: + + ```console + sampledb=# SELECT * FROM users; + id | name | email + ----+-------+------------------- + 1 | Alpha | alpha@example.com + 2 | Beta | beta@example.com + 3 | Gamma | gamma@example.com + (3 rows) + ``` + + Use `\q` or `\quit` to exit from the Postgres interactive shell. + +## Pre-seed the database by bind-mounting a SQL script + +In Docker, mounting refers to making files or directories from the host system accessible within a container. This let you to share data or configuration files between the host and the container, enabling greater flexibility and persistence. + +Now that you have learned how to launch Postgres and pre-seed the database using an SQL script, it’s time to learn how to mount an SQL file directly into the Postgres containers’ initialization directory (`/docker-entrypoint-initdb.d`). The `/docker-entrypoint-initdb.d` is a special directory in PostgreSQL Docker containers that is used for initializing the database when the container is first started + +Make sure you stop any running Postgres containers (along with volumes) to prevent port conflicts before you follow the steps: + +```console +$ docker container stop postgres +``` + +1. Modify the `seed.sql` with the following entries: + + ```sql + CREATE TABLE IF NOT EXISTS users ( + id SERIAL PRIMARY KEY, + name VARCHAR(50), + email VARCHAR(100) UNIQUE + ); + + INSERT INTO users (name, email) VALUES + ('Alpha', 'alpha@example.com'), + ('Beta', 'beta@example.com'), + ('Gamma', 'gamma@example.com') + ON CONFLICT (email) DO NOTHING; + ``` + +2. Create a text file named `Dockerfile` and copy the following content. + + ```plaintext + # syntax=docker/dockerfile:1 + FROM postgres:18 + COPY seed.sql /docker-entrypoint-initdb.d/ + ``` + + This Dockerfile copies the `seed.sql` script directly into the PostgreSQL container's initialization directory. + + +3. Use Docker Compose. + + Using Docker Compose makes it even easier to manage and deploy the PostgreSQL container with the seeded database. This compose.yml file defines a Postgres service named `db` using the latest Postgres image, which sets up a database with the name `sampledb`, along with a user `postgres` and a password `mysecretpassword`. + + ```yaml + services: + db: + build: + context: . + dockerfile: Dockerfile + container_name: my_postgres_db + environment: + POSTGRES_USER: postgres + POSTGRES_PASSWORD: mysecretpassword + POSTGRES_DB: sampledb + ports: + - "5432:5432" + volumes: + - data_sql:/var/lib/postgresql # Persistent data storage + + volumes: + data_sql: + ``` + + It maps port `5432` on the host to the container's `5432`, let you access to the Postgres database from outside the container. It also define `data_sql` for persisting the database data, ensuring that data is not lost when the container is stopped. + + It is important to note that the port mapping to the host is only necessary if you want to connect to the database from non-containerized programs. If you containerize the service that connects to the DB, you should connect to the database over a custom bridge network. + +4. Bring up the Compose service. + + Assuming that you've placed the `seed.sql` file in the same directory as the Dockerfile, execute the following command: + + ```console + $ docker compose up -d --build + ``` + +5. It’s time to verify if the table `users` get populated with the data. + + ```console + $ docker exec -it my_postgres_db psql -h localhost -U postgres sampledb + ``` + + ```sql + sampledb=# SELECT * FROM users; + id | name | email + ----+-------+------------------- + 1 | Alpha | alpha@example.com + 2 | Beta | beta@example.com + 3 | Gamma | gamma@example.com + (3 rows) + + sampledb=# + ``` + + +## Pre-seed the database using JavaScript code + + +Now that you have learned how to seed the database using various methods like SQL script, mounting volumes etc., it's time to try to achieve it using JavaScript code. + +1. Create a .env file with the following: + + ```plaintext + POSTGRES_USER=postgres + POSTGRES_DB_HOST=localhost + POSTGRES_DB=sampledb + POSTGRES_PASSWORD=mysecretpassword + POSTGRES_PORT=5432 + ``` + +2. Create a new JavaScript file called seed.js with the following content: + + The following JavaScript code imports the `dotenv` package which is used to load environment variables from an `.env` file. The `.config()` method reads the `.env` file and sets the environment variables as properties of the `process.env` object. This let you to securely store sensitive information like database credentials outside of your code. + + Then, it creates a new Pool instance from the pg library, which provides a connection pool for efficient database interactions. The `seedData` function is defined to perform the database seeding operations. +It is called at the end of the script to initiate the seeding process. The try...catch...finally block is used for error handling. + + ```plaintext + require('dotenv').config(); // Load environment variables from .env file + const { Pool } = require('pg'); + + // Create a new pool using environment variables + const pool = new Pool({ + user: process.env.POSTGRES_USER, + host: process.env.POSTGRES_DB_HOST, + database: process.env.POSTGRES_DB, + port: process.env.POSTGRES_PORT, + password: process.env.POSTGRES_PASSWORD, + }); + + const seedData = async () => { + try { + // Drop the table if it already exists (optional) + await pool.query(`DROP TABLE IF EXISTS todos;`); + + // Create the table with the correct structure + await pool.query(` + CREATE TABLE todos ( + id SERIAL PRIMARY KEY, + task VARCHAR(255) NOT NULL, + completed BOOLEAN DEFAULT false + ); + ` ); + + // Insert seed data + await pool.query(` + INSERT INTO todos (task, completed) VALUES + ('Watch netflix', false), + ('Finish podcast', false), + ('Pick up kid', false); + `); + console.log('Database seeded successfully!'); + } catch (err) { + console.error('Error seeding the database', err); + } finally { + pool.end(); + } + }; + + // Call the seedData function to run the script + seedData(); + ``` + +3. Kick off the seeding process + + ```console + $ node seed.js + ``` + + You should see the following command: + + ```plaintext + Database seeded successfully! + ``` + +4. Verify if the database is seeded correctly: + + ```console + $ docker exec -it postgres psql -h localhost -U postgres sampledb + ``` + + ```console + sampledb=# SELECT * FROM todos; + id | task | completed + ----+----------------+----------- + 1 | Watch netflix | f + 2 | Finish podcast | f + 3 | Pick up kid | f + (3 rows) + ``` + +## Recap + +Pre-seeding a database with schema and data at startup is essential for creating a consistent and realistic testing environment, which helps in identifying issues early in development and aligning frontend and backend work.

Update the package manager: + + ```console + $ sudo apt update + ``` + +2. Install the Turtlesim package: + + ```console + $ sudo apt install -y ros-humble-turtlesim + ``` + +3. Run the Turtlesim node: + + ```console + $ ros2 run turtlesim turtlesim_node + ``` + +A window should appear on your desktop showing a turtle in a grid. + +## Control the turtle + +1. Open a new terminal and connect to the same container, then start the keyboard teleop node: + + ```console + $ ros2 run turtlesim turtle_teleop_key + ``` + + This node allows you to control the turtle using your keyboard. Use the arrow keys to move the turtle forward, backward, left, and right. Press `Ctrl+C` to stop the teleop node. + +2. Move the turtle around the window. You should see it draw a path as it moves. + +## Monitor topics + +1. Open another terminal and connect to the same container, then list all active topics: + + ```console + $ ros2 topic list + ``` + + You should see output similar to the following: + + ```text + /parameter_events + /rosout + /turtle1/cmd_vel + /turtle1/color_sensor + /turtle1/pose + ``` + +2. Get information about a specific topic: + + ```console + $ ros2 topic info /turtle1/pose + ``` + + You'll see the topic type and which nodes publish and subscribe to it. + +## Visualize the system with rqt + +1. Open another terminal and connect to the same container, then update the package manager: + + ```console + $ sudo apt update + ``` + +2. Install rqt: + + ```console + $ sudo apt install -y 'ros-humble-rqt*' + ``` + +3. Start rqt: + + ```console + $ ros2 run rqt_gui rqt_gui + ``` + +An rqt window should appear. rqt provides several useful plugins for visualizing and monitoring ROS 2 systems. + +### Node Graph + +You can explore the node graph by navigating to **Plugins > Introspection > Node Graph**. A new tab opens showing nodes and topics with connections illustrated as lines. This visualization demonstrates how the teleop node sends velocity commands to the Turtlesim node, and how the Turtlesim node publishes position data back through topics. + +### Topic Monitor + +You can monitor active topics by navigating to **Plugins > Topics > Topic Monitor**. A new tab opens displaying all active topics and their current values. Select the eye icon next to `/turtle1/pose` to monitor it. As you move the turtle, watch the pose values update in real time, showing the position of the turtle and orientation changing based on your commands. + +### Service Caller + +You can call services from rqt using **Plugins > Services > Service Caller**. Select a service such as `/turtle1/teleport_absolute`, enter values for the request fields, and select **Call** to send the request. + +### Plots + +To plot topic data over time navigate to **Plugins > Visualization > Plot**. For example, in the Plot window, type `/turtle1/pose/x` in the Topic field and press Enter. Move the turtle and watch the X position displayed as a graph over time. + +## Call ROS 2 services + +Turtlesim provides services for actions such as repositioning the turtle and clearing the path. + +1. List available services: + + ```console + $ ros2 service list + ``` + + You should see services such as `/turtle1/set_pen` (to change pen color and width), `/turtle1/teleport_absolute` (to move the turtle to a specific position), and `/turtle1/teleport_relative` (to move the turtle relative to its current position). + +2. Teleport the turtle to a new position: + + ```console + $ ros2 service call /turtle1/teleport_absolute turtlesim/srv/TeleportAbsolute " + x: 1.0 + y: 3.0 + theta: 0.0 + " + ``` + + The turtle should instantly move to the specified position (1.0, 3.0). + +## Create a simple publisher + +1. Create a Python script that publishes velocity commands to control the turtle programmatically. In a new terminal, create a file called `move_turtle.py`: + + ```python + import rclpy + from geometry_msgs.msg import Twist + import time + + def main(): + rclpy.init() + node = rclpy.create_node('turtle_mover') + publisher = node.create_publisher(Twist, 'turtle1/cmd_vel', 10) + + # Create a twist message + msg = Twist() + msg.linear.x = 2.0 # Move forward at 2 m/s + msg.angular.z = 1.0 # Rotate at 1 rad/s + + # Publish the message + for i in range(50): + publisher.publish(msg) + time.sleep(0.1) + + # Stop the turtle + msg.linear.x = 0.0 + msg.angular.z = 0.0 + publisher.publish(msg) + + node.destroy_node() + rclpy.shutdown() + + if __name__ == '__main__': + main() + ``` + +2. Run the script: + + ```console + $ python3 move_turtle.py + ``` + + The turtle should move in a circular motion for 5 seconds and then stop. + +## Summary + +In this section, you configured display forwarding, used the Turtlesim nodes, inspected nodes and topics, and visualized the system using rqt. Finally, you interacted with ROS 2 services and created a simple publisher to move the turtle programmatically. + +These fundamental concepts apply directly to real-world robotics applications with actual sensors and actuators. + +## Related resources + +- [ROS 2 Turtlesim tutorials](https://docs.ros.org/en/humble/Tutorials/Beginner-CLI-Tools/Understanding-ROS2-Topics/Understanding-ROS2-Topics.html) +- [ROS 2 Concepts](https://docs.ros.org/en/humble/Concepts.html) +- [Geometry Messages](https://github.com/ros2/geometry2/tree/humble/geometry_msgs) diff --git a/content/guides/ruby/_index.md b/content/guides/ruby/_index.md new file mode 100644 index 000000000000..5652dc7fe5b2 --- /dev/null +++ b/content/guides/ruby/_index.md @@ -0,0 +1,27 @@ +--- +title: Ruby on Rails language-specific guide +linkTitle: Ruby +description: Containerize Ruby on Rails apps using Docker +keywords: Docker, getting started, ruby, language +summary: | + This guide explains how to containerize Ruby on Rails applications using + Docker. +toc_min: 1 +toc_max: 2 +aliases: + - /language/ruby/ + - /guides/language/ruby/ +languages: [ruby] +tags: [frameworks] +params: + time: 20 minutes +--- + +The Ruby language-specific guide teaches you how to containerize a Ruby on Rails application using Docker.

It allows you to define custom workflows for building, testing, and deploying your code when specific events occur (e.g., pushing code, creating a pull request, etc.). A workflow is a YAML-based automation script that defines a sequence of steps to be executed when triggered. Workflows are stored in the `.github/workflows/` directory of a repository. + +In this section, you'll learn how to set up and use GitHub Actions to build your Docker image as well as push it to Docker Hub. You will complete the following steps: + +1. Define the GitHub Actions workflow. +2. Run the workflow. + +## 1. Define the GitHub Actions workflow + +You can create a GitHub Actions workflow by creating a YAML file in the `.github/workflows/` directory of your repository. To do this use your favorite text editor or the GitHub web interface. The following steps show you how to create a workflow file using the GitHub web interface. + +If you prefer to use the GitHub web interface, follow these steps: + +1. Go to your repository on GitHub and then select the **Actions** tab. + +2. Select **set up a workflow yourself**. + + This takes you to a page for creating a new GitHub Actions workflow file in + your repository. By default, the file is created under `.github/workflows/main.yml`, let's change it name to `build.yml`. + +If you prefer to use your text editor, create a new file named `build.yml` in the `.github/workflows/` directory of your repository. + +Add the following content to the file: + +```yaml +name: Build and push Docker image + +on: + push: + branches: + - main + +jobs: + build_and_push: + runs-on: ubuntu-latest + steps: + - name: Login to Docker Hub + uses: docker/login-action@{{% param "login_action_version" %}} + with: + username: ${{ vars.DOCKER_USERNAME }} + password: ${{ secrets.DOCKERHUB_TOKEN }} + + - name: Set up Docker Buildx + uses: docker/setup-buildx-action@{{% param "setup_buildx_action_version" %}} + + - name: Build and push + uses: docker/build-push-action@{{% param "build_push_action_version" %}} + with: + push: true + tags: ${{ vars.DOCKER_USERNAME }}/${{ github.event.repository.name }}:latest +``` + +Each GitHub Actions workflow includes one or several jobs. Each job consists of steps. Each step can either run a set of commands or use already [existing actions](https://github.com/marketplace?type=actions). The action above has three steps: + +1. [**Login to Docker Hub**](https://github.com/docker/login-action): Action logs in to Docker Hub using the Docker ID and Personal Access Token (PAT) you created earlier. + +2. [**Set up Docker Buildx**](https://github.com/docker/setup-buildx-action): Action sets up Docker [Buildx](https://github.com/docker/buildx), a CLI plugin that extends the capabilities of the Docker CLI. + +3. [**Build and push**](https://github.com/docker/build-push-action): Action builds and pushes the Docker image to Docker Hub. The `tags` parameter specifies the image name and tag. The `latest` tag is used in this example. + +## 2. Run the workflow + +Commit the changes and push them to the `main` branch. This workflow is runs every time you push changes to the `main` branch. You can find more information about workflow triggers [in the GitHub documentation](https://docs.github.com/en/actions/writing-workflows/choosing-when-your-workflow-runs/events-that-trigger-workflows). + +Go to the **Actions** tab of you GitHub repository. It displays the workflow. Selecting the workflow shows you the breakdown of all the steps. + +When the workflow is complete, go to your [repositories on Docker Hub](https://hub.docker.com/repositories).

Replace `DOCKER_USERNAME/REPO_NAME` with your Docker +username and the name of the repository that you created in [Configure CI/CD for +your Ruby on Rails application](configure-github-actions.md). + +```yaml +apiVersion: apps/v1 +kind: Deployment +metadata: + name: docker-ruby-on-rails-demo + namespace: default +spec: + replicas: 1 + selector: + matchLabels: + service: ruby-on-rails + template: + metadata: + labels: + service: ruby-on-rails + spec: + containers: + - name: ruby-on-rails-container + image: DOCKER_USERNAME/REPO_NAME + imagePullPolicy: Always +--- +apiVersion: v1 +kind: Service +metadata: + name: docker-ruby-on-rails-demo + namespace: default +spec: + type: NodePort + selector: + service: ruby-on-rails + ports: + - port: 3000 + targetPort: 3000 + nodePort: 30001 +``` + +In this Kubernetes YAML file, there are two objects, separated by the `---`: + +- A Deployment, describing a scalable group of identical pods. In this case, + you'll get just one replica, or copy of your pod. That pod, which is + described under `template`, has just one container in it. The + container is created from the image built by GitHub Actions in [Configure CI/CD for + your Ruby on Rails application](configure-github-actions.md). +- A NodePort service, which will route traffic from port 30001 on your host to + port 8001 inside the pods it routes to, allowing you to reach your app + from the network. + +To learn more about Kubernetes objects, see the [Kubernetes documentation](https://kubernetes.io/docs/home/). + +## Deploy and check your application + +1. In a terminal, navigate to `docker-ruby-on-rails` and deploy your application to + Kubernetes. + + ```console + $ kubectl apply -f docker-ruby-on-rails-kubernetes.yaml + ``` + + You should see output that looks like the following, indicating your Kubernetes objects were created successfully. + + ```shell + deployment.apps/docker-ruby-on-rails-demo created + service/docker-ruby-on-rails-demo created + ``` + +2. Make sure everything worked by listing your deployments. + + ```console + $ kubectl get deployments + ``` + + Your deployment should be listed as follows: + + ```shell + NAME READY UP-TO-DATE AVAILABLE AGE + docker-ruby-on-rails-demo 1/1 1 1 15s + ``` + + This indicates all one of the pods you asked for in your YAML are up and running. Do the same check for your services. + + ```console + $ kubectl get services + ``` + + You should get output like the following. + + ```shell + NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE + kubernetes ClusterIP 10.96.0.1 443/TCP 23h + docker-ruby-on-rails-demo NodePort 10.99.128.230 3000:30001/TCP 75s + ``` + + In addition to the default `kubernetes` service, you can see your `docker-ruby-on-rails-demo` service, accepting traffic on port 30001/TCP. + +3. To create and migrate the database in a Ruby on Rails application running on Kubernetes, you need to follow these steps. + + **Get the Current Pods**: + First, you need to identify the pods running in your Kubernetes cluster. Execute the following command to list the current pods in the `default` namespace: + + ```sh + # Get the current pods in the cluster in the namespace default + $ kubectl get pods + ``` + + This command will display a list of all pods in the `default` namespace. Look for the pod with the prefix `docker-ruby-on-rails-demo-`. Here is an example output: + + ```console + NAME READY STATUS RESTARTS AGE + docker-ruby-on-rails-demo-7cbddb5d6f-qh44l 1/1 Running 2 (22h ago) 9d + ``` + + **Execute the Migration Command**: + Once you've identified the correct pod, use the `kubectl exec` command to run the database migration inside the pod. + + ```sh + $ kubectl exec -it docker-ruby-on-rails-demo-7cbddb5d6f-qh44l -- rails db:migrate RAILS_ENV=development + ``` + + This command opens an interactive terminal session (`-it`) in the specified pod and runs the `rails db:migrate` command with the environment set to development (`RAILS_ENV=development`). + + By following these steps, you ensure that your database is properly migrated within the Ruby on Rails application running in your Kubernetes cluster. This process helps maintain the integrity and consistency of your application's data structure during deployment and updates. + +4. Open the browser and go to [http://localhost:30001](http://localhost:30001), you should see the ruby on rails application working. + +5.

The Swarm environment created by Docker Desktop is fully featured, meaning it has all the Swarm features your app will enjoy on a real cluster, accessible from the convenience of your development machine. + +## Describe apps using stack files + +Swarm never creates individual containers like you did in the previous step of this tutorial. Instead, all Swarm workloads are scheduled as services, which are scalable groups of containers with added networking features maintained automatically by Swarm. Furthermore, all Swarm objects can and should be described in manifests called stack files. These YAML files describe all the components and configurations of your Swarm app, and can be used to create and destroy your app in any Swarm environment. + +Now you can write a simple stack file to run and manage your Todo app, the container `getting-started` image created in [Part 2](02_our_app.md) of the tutorial.

In this case, you'll get just one container (the default), and that container will be based on your `getting-started` image created in [Part 2](02_our_app.md) of the tutorial. In addition, you've asked Swarm to forward all traffic arriving at port 8000 on your development machine to port 3000 inside our getting-started container. + +> **Kubernetes Services and Swarm Services are very different** +> +> Despite the similar name, the two orchestrators mean very different things by +> the term 'service'.

You might have both an API and a frontend app, a WireMock service to mock data endpoints, or a database visualizer (such as phpMyAdmin or pgAdmin).

When using the Docker provider, Traefik gets its configuration from other running containers using [labels](https://docs.docker.com/config/labels-custom-metadata/). Traefik will watch engine events (for container starts and stops), extract the labels, and update its configuration. + +While there are [many Traefik-monitored labels](https://doc.traefik.io/traefik/routing/providers/docker/), the two most common will be: + +- `traefik.http.routers..rule` - used to indicate the routing rule ([view all of the available rules here](https://doc.traefik.io/traefik/routing/routers/#rule)) +- `traefik.http.services..loadbalancer.server.port` - indicates the port Traefik should forward the request to. Note that this container port does not need to be exposed on your host machine ([read about port detection here](https://doc.traefik.io/traefik/providers/docker/#port-detection)) + +Let’s do a quick demo of starting Traefik and then configuring two additional containers to be accessible using different hostnames. + +1. In order for two containers to be able to communicate with each other, they need to be on the same network. Create a network named `traefik-demo` using the `docker network create` command: + + ```console + $ docker network create traefik-demo + ``` + +2. Start a Traefik container using one of the following methods. These commands exposes Traefik on port 80, mounts the Docker socket (which is used to monitor containers to update configuration), and passes the `--providers.docker` argument to configure Traefik to use the Docker provider. + + {{< tabs >}} + {{< tab name="Using Docker Hardened Images" >}} + + Docker Hardened Images (DHI) for Traefik are available on [Docker Hub](https://hub.docker.com/hardened-images/catalog/dhi/traefik). + If you haven't authenticated yet, first run: + + ```bash + $ docker login dhi.io + ``` + + Then start a container using the Hardened image: + + ```console + $ docker run -d --network=traefik-demo \ + -p 80:80 \ + -v /var/run/docker.sock:/var/run/docker.sock \ + dhi.io/traefik:3.6.2 \ + --providers.docker + ``` + + {{< /tab >}} + + {{< tab name="Using the official image" >}} + + You can also use the official image from Docker Hub: + + ```console + $ docker run -d --network=traefik-demo \ + -p 80:80 \ + -v /var/run/docker.sock:/var/run/docker.sock \ + traefik:v3.6.2 \ + --providers.docker + ``` + + {{< /tab >}} + {{< /tabs >}} + +3. Now, start a simple Nginx container and define the labels Traefik is watching for to configure the HTTP routing. Note that the Nginx container is not exposing any ports. + + {{< tabs >}} + {{< tab name="Using Docker Hardened Images" >}} + + Docker Hardened Images (DHI) for Nginx are available on [Nginx DHI image](https://hub.docker.com/hardened-images/catalog/dhi/nginx). + If you haven't authenticated yet, first run: + + ```bash + $ docker login dhi.io + ``` + + ```console + $ docker run -d --network=traefik-demo \ + --label 'traefik.http.routers.nginx.rule=Host(`nginx.localhost`)' \ + dhi.io/nginx:1.29.3 + ``` + + {{< /tab >}} + + {{< tab name="Using the official image" >}} + + You can also run the official Nginx image as follows: + + ```console + $ docker run -d --network=traefik-demo \ + --label 'traefik.http.routers.nginx.rule=Host(`nginx.localhost`)' \ + nginx:1.29.3 + ``` + + {{< /tab >}} + {{< /tabs >}} + + Once the container starts, open your browser to [http://nginx.localhost](http://nginx.localhost) to see the app (all Chromium-based browsers route \*.localhost requests locally with no additional setup). + +4. Start a second application that will use a different hostname. + + ```console + $ docker run -d --network=traefik-demo --label 'traefik.http.routers.welcome.rule=Host(`welcome.localhost`)' docker/welcome-to-docker + ``` + + Once the container starts, open your browser to http://welcome.localhost. You should see a “Welcome to Docker” website. + +## Using Traefik in development + +Now that you’ve experienced Traefik, it’s time to try using it in a development environment. In this example, you will use a sample application that has a split frontend and backend. This app stack has the following configuration: + +1. All requests to /api to go to the API service +2. All other requests to localhost go to the frontend client +3. Since the app uses MySQL, db.localhost should provide phpMyAdmin to make it easy to access the database during development + +![Architecture diagram showing Traefik routing requests to other containers based on the path of the request](./images/traefik-in-development.webp) + +The application can be accessed on GitHub at [dockersamples/easy-http-routing-with-traefik](https://github.com/dockersamples/easy-http-routing-with-traefik). + +1. In the `compose.yaml` file, Traefik is using the following configuration: + + {{< tabs >}} + {{< tab name="Using DHI image" >}} + + ```yaml + services: + proxy: + image: dhi.io/traefik:3.6.2 + command: --providers.docker + ports: + - 80:80 + volumes: + - /var/run/docker.sock:/var/run/docker.sock + ``` + + {{< /tab >}} + + {{< tab name="Using official image" >}} + + ```yaml + services: + proxy: + image: traefik:v3.6.2 + command: --providers.docker + ports: + - 80:80 + volumes: + - /var/run/docker.sock:/var/run/docker.sock + ``` + + {{< /tab >}} + {{< /tabs >}} + + Note that this is essentially the same configuration as used earlier, but now in a Compose syntax. + +2. The client service has the following configuration, which will start the container and provide it with the labels to receive requests at localhost. + + {{< tabs >}} + {{< tab name="Using Docker Hardened Images" >}} + + Docker Hardened Images (DHI) for Nginx are available on [Nginx DHI image](https://hub.docker.com/hardened-images/catalog/dhi/nginx). + + If you haven't authenticated yet, first run: + + ```bash + $ docker login dhi.io + ``` + + You can use it as your base image as shown following: + + ```yaml + services: + # â€Ļ + client: + image: dhi.io/nginx:1.29.3-alpine3.21 + volumes: + - "./client:/usr/share/nginx/html" + labels: + traefik.http.routers.client.rule: "Host(`localhost`)" + ``` + + {{< /tab >}} + + {{< tab name="Using the official image" >}} + + ```yaml + services: + # â€Ļ + client: + image: nginx:1.29.3-alpine3.22 + volumes: + - "./client:/usr/share/nginx/html" + labels: + traefik.http.routers.client.rule: "Host(`localhost`)" + ``` + + {{< /tab >}} + {{< /tabs >}} + +3. The api service has a similar configuration, but you’ll notice the routing rule has two conditions - the host must be “localhost” and the URL path must have a prefix of “/api”. Since this rule is more specific, Traefik will evaluate it first compared to the client rule. + + ```yaml {hl_lines=[7,8]} + services: + # â€Ļ + api: + build: ./dev/api + volumes: + - "./api:/var/www/html/api" + labels: + traefik.http.routers.api.rule: "Host(`localhost`) && PathPrefix(`/api`)" + ``` + +4. And finally, the `phpmyadmin` service is configured to receive requests for the hostname “db.localhost”. The service also has environment variables defined to automatically log in, making it a little easier to get into the app. + + ```yaml {hl_lines=[5,6]} + services: + # â€Ļ + phpmyadmin: + image: phpmyadmin:5.2.1 + labels: + traefik.http.routers.db.rule: "Host(`db.localhost`)" + environment: + PMA_USER: root + PMA_PASSWORD: password + ``` + +5. Before starting the stack, stop the Nginx container if it is still running. + + And that’s it. Now, you only need to spin up the Compose stack with a `docker compose up` and all of the services and applications will be ready for development. + +## Sending traffic to non-containerized workloads + +In some situations, you may want to forward requests to applications not running in containers. In the following architecture diagram, the same application from before is used, but the API and React apps are now running natively on the host machine. + +![An architecture diagram showing several components and the routing between them. Traefik is able to send requests to both non-containerized and containerized workloads](images/traefik-non-containerized-workload-architecture.webp) + +To accomplish this, Traefik will need to use another method to configure itself. The [File provider](https://doc.traefik.io/traefik/providers/file/) lets you define the routing rules in a YAML document. Here is an example file: + +```yaml +http: + routers: + native-api: + rule: "Host(`localhost`) && PathPrefix(`/api`)" + service: native-api + native-client: + rule: "Host(`localhost`)" + service: native-client + + services: + native-api: + loadBalancer: + servers: + - url: "http://host.docker.internal:3000/" + native-client: + loadBalancer: + servers: + - url: "http://host.docker.internal:5173/" +``` + +This configuration indicates that requests that for `localhost/api` will be forwarded to a service named `native-api`, which then forwards the request to http://host.docker.internal:3000. The hostname `host.docker.internal` is a name that Docker Desktop provides to send requests to the host machine. + +With this file, the only change is to the Compose configuration for Traefik. There are specifically two things that have changed: + +1. The configuration file is mounted into the Traefik container (the exact destination path is up to you) +2. The `command` is updated to add the file provider and point to the location of the configuration file + + {{< tabs >}} + {{< tab name="Using DHI image" >}} + + ```yaml + services: + proxy: + image: dhi.io/traefik:3.6.2 + command: --providers.docker --providers.file.filename=/config/traefik-config.yaml --api.insecure + ports: + - 80:80 + - 8080:8080 + volumes: + - /var/run/docker.sock:/var/run/docker.sock + - ./dev/traefik-config.yaml:/config/traefik-config.yaml + ``` + + {{< /tab >}} + + {{< tab name="Using official image" >}} + + ```yaml + services: + proxy: + image: traefik:v3.6.2 + command: --providers.docker --providers.file.filename=/config/traefik-config.yaml --api.insecure + ports: + - 80:80 + - 8080:8080 + volumes: + - /var/run/docker.sock:/var/run/docker.sock + - ./dev/traefik-config.yaml:/config/traefik-config.yaml + ``` + + {{< /tab >}} + {{< /tabs >}} + +### Starting the example app + +To run the example app that forwards requests from Traefik to native-running apps, use the following steps: + +1. If you have the Compose stack still running, stop it with the following command: + + ```console + $ docker compose down + ``` + +2. Start the application using the provided `compose-native.yaml` file: + + ```console + $ docker compose -f compose-native.yaml up + ``` + + Opening [http://localhost](http://localhost) will return a 502 Bad Gateway because the other apps aren’t running yet. + +3. Start the API by running the following steps: + + ```console + cd api + yarn install + yarn dev + ``` + +4. Start the frontend by running the following steps in a new terminal (starting from the root of the project): + + ```console + cd client + yarn install + yarn dev + ``` + +5. Open the app at [http://localhost](http://localhost). You should see an app that fetches a message from [http://localhost/api/messages](http://localhost/api/messages). You can also open [http://db.localhost](http://db.localhost) to view or adjust the available messages directly from the Mongo database. Traefik will ensure the requests are properly routed to the correct container or application. + +6. When you’re done, run `docker compose down` to stop the containers and stop the Yarn apps by hitting `ctrl+c`. + +## Recap + +Running multiple services doesn’t have to require tricky port configuration and a good memory. With tools like Traefik, it’s easy to launch the services you need and easily access them - whether they’re for the app itself (such as the frontend and backend) or for additional development tooling (such as phpMyAdmin). diff --git a/content/guides/use-case/_index.md b/content/guides/use-case/_index.md deleted file mode 100644 index e8f55f27fa15..000000000000 --- a/content/guides/use-case/_index.md +++ /dev/null @@ -1,77 +0,0 @@ ---- -title: Use-case guides -keywords: guide, use-case -description: Learn how to accomplish tasks with Docker. -notoc: true - -grid_genai: -- title: PDF analysis and chat - description: Learn how to containerize a GenAI app that analyzes PDFs. - icon: article - link: /guides/use-case/genai-pdf-bot/ -- title: Video transcription and chat - description: Explore a video transcription app that lets you ask questions about videos. - icon: play_circle - link: /guides/use-case/genai-video-bot/ -- title: Face detection with TensorFlow.js - description: Explore a face detection app built with TensorFlow.js and Docker. - icon: face - link: /guides/use-case/tensorflowjs/ -- title: Language translation - description: Build and run an app to translate languages. - link: /guides/use-case/nlp/language-translation/ - icon: translate -- title: Named entity recognition - description: Explore an app that can identify named entities, like people, organizations, or locations. - link: /guides/use-case/nlp/named-entity-recognition/ - icon: badge -- title: Sentiment analysis - description: Learn how to analyze text for sentiment, like positive, negative, or neutral. - link: /guides/use-case/nlp/sentiment-analysis/ - icon: sentiment_very_satisfied -- title: Text classification - description: Build a text classification app and analyze the precision of your model. - link: /guides/use-case/nlp/text-classification/ - icon: text_snippet -- title: Text summarization - description: Explore an app that can summarize text. - link: /guides/use-case/nlp/text-summarization/ - icon: summarize ---- - -Explore this collection of use-case guides designed to help you leverage Docker -for a variety of advanced applications.

Set your AccuWeather API key using the `.env` file: + + > [!TIP] + > To prevent conflicts, ensure that any existing environment variables named `API_ENDPOINT_BASE` or `ACCUWEATHER_API_KEY` are removed before modifying the `.env` file. + + Run the following command on your terminal: + + ```console + unset API_ENDPOINT_BASE + unset ACCUWEATHER_API_KEY + ``` + + It’s time to set the environment variables in the `.env` file: + + ```plaintext + ACCUWEATHER_API_KEY=XXXXXX + API_ENDPOINT_BASE=http://dataservice.accuweather.com + ``` + + Make sure to populate `ACCUWEATHER_API_KEY` with the correct value. + +4. Install the dependencies + + Run the following command to install the required packages: + + ```console + $ npm install + ``` + + This will install all the packages listed in your `package.json` file. These packages are essential for the project to function correctly. + + If you encounter any warnings related to deprecated packages, you can ignore them for now for this demonstration. + +5. Assuming that you don’t have a pre-existing Node server running on your system, go ahead and start the Node server by running the following command: + + ```console + $ npm run start + ``` + + You should see the following output: + + ```plaintext + > express-api-starter@1.2.0 start + > node src/index.js + + API_ENDPOINT_BASE: http://dataservice.accuweather.com + ACCUWEATHER_API_KEY is set: true + Listening: http://localhost:5001 + ``` + + Keep this terminal window open. + +6. Run the curl command to send a GET request to the server URL. + + In the new terminal window, enter the following command: + + ```console + $ curl "http://localhost:5000/api/v1/getWeather?city=Bengaluru" + ``` + + By running the command, you're essentially telling your local server to provide you with weather data for a city named `Bengaluru`. The request is specifically targeting the `/api/v1/getWeather` endpoint, and you're providing the query parameter `city=Bengaluru`. Once you execute the command, the server processes this request, fetches the data and returns it as a response, which `curl` will display in your terminal. + + When fetching data from the external AccuWeather API, you're interacting with live data that reflects the latest weather conditions. + + +## Recap + +This guide has walked you through setting up WireMock using Docker. You’ve learned how to create stubs to simulate API endpoints, allowing you to develop and test your application without relying on external services. By using WireMock, you can create reliable and consistent test environments, reproduce edge cases, and speed up your development workflow. + diff --git a/content/guides/workshop/02_our_app.md b/content/guides/workshop/02_our_app.md deleted file mode 100644 index e071665dcfd5..000000000000 --- a/content/guides/workshop/02_our_app.md +++ /dev/null @@ -1,212 +0,0 @@ ---- -title: Containerize an application -keywords: dockerfile example, Containerize an application, run docker file, running - docker file, how to run dockerfile, example dockerfile, how to create a docker container, - create dockerfile, simple dockerfile, creating containers -description: Follow this step-by-step guide to learn how to create and run a containerized - application using Docker -aliases: -- /get-started/part2/ -- /get-started/02_our_app/ ---- - -For the rest of this guide, you'll be working with a simple todo -list manager that runs on Node.js.

Docker makes these capabilities approachable and easy to use. To summarize, a container: - -- Is a runnable instance of an image.

While Zscaler ensures security compliance +and network control, it can cause issues for developers using Docker, +particularly during build processes, where SSL certificate validation errors +might occur. This guide outlines how to configure Docker containers and builds +to properly handle Zscaler's custom certificates, ensuring smooth operation in +monitored environments. + +## The role of certificates in Docker + +When Docker builds or runs containers, it often needs to fetch resources from +the internet—whether it's pulling a base image from a registry, downloading +dependencies, or communicating with external services. In a proxied +environment, Zscaler intercepts HTTPS traffic and replaces the remote server's +certificate with its own. However, Docker doesn't trust this Zscaler +certificate by default, leading to SSL errors. + +```plaintext +x509: certificate signed by unknown authority +``` + +These errors occur because Docker cannot verify the validity of the certificate +presented by Zscaler. To avoid this, you must configure Docker to trust +Zscaler's certificate. + +## Configure Zscaler proxy for Docker Desktop + +Depending on how Zscaler is deployed, you may need to configure Docker Desktop +proxy settings manually to use the Zscaler proxy. + +If you're using Zscaler as a system-level proxy via the [Zscaler Client Connector](https://help.zscaler.com/zscaler-client-connector/what-is-zscaler-client-connector), +all traffic on the device is automatically routed through Zscaler, so Docker +Desktop uses the Zscaler proxy automatically with no additional configuration +necessary. + +If you are not using Zscaler as a system-level proxy, manually configure proxy +settings in Docker Desktop. Set up proxy settings for all clients in the +organization using [Settings Management](/manuals/enterprise/security/hardened-desktop/settings-management/_index.md), +or edit proxy configuration in the Docker Desktop GUI under [**Settings > Resources > Proxies**](/manuals/desktop/settings-and-maintenance/settings.md#proxies). + +## Install root certificates in Docker images + +To enable containers to use and trust the Zscaler proxy, embed the certificate +in the image and configure the image's trust store. Installing certificates at +image build time is the preferred approach, as it removes the need for +configuration during startup and provides an auditable, consistent environment. + +### Obtaining the root certificate + +The easiest way to obtain the root certificate is to export it from a machine +where an administrator has already installed it. You can use either a web +browser or the system's certificate management service (for example, Windows +Certificate Store). + +#### Example: Exporting the certificate using Google Chrome + +1. In Google Chrome, navigate to `chrome://certificate-manager/`. +2. Under **Local certificates**, select **View imported certificates**. +3. Find the Zscaler root certificate, often labeled **Zscaler Root CA**. +4. Open the certificate details and select **Export**. +5. Save the certificate in ASCII PEM format. +6. Open the exported file in a text editor to confirm it includes `-----BEGIN CERTIFICATE-----` and `-----END CERTIFICATE-----`. + +When you have obtained the certificate, store it in an accessible repository, +such as JFrog Artifactory or a Git repository. Alternatively, use generic +storage like AWS S3. + +### Building with the certificate + +To install these certificates when building images, copy the certificate into +the build container and update the trust store. An example Dockerfile looks +like this: + +```dockerfile +FROM debian:bookworm +COPY zscaler-root-ca.crt /usr/local/share/ca-certificates/zscaler-root-ca.crt +RUN apt-get update && \ + apt-get install -y ca-certificates && \ + update-ca-certificates +``` + +Here, `zscaler-root-ca.crt` is the root certificate, located at the root of the +build context (often within the application's Git repository). + +If you use an artifact repository, you can fetch the certificate directly using +the `ADD` instruction. You can also use the `--checksum` flag to verify that +the content digest of the certificate is correct. + +```dockerfile +FROM debian:bookworm +ADD --checksum=sha256:24454f830cdb571e2c4ad15481119c43b3cafd48dd869a9b2945d1036d1dc68d \ + https://artifacts.example/certs/zscaler-root-ca.crt /usr/local/share/ca-certificates/zscaler-root-ca.crt +RUN apt-get update && \ + apt-get install -y ca-certificates && \ + update-ca-certificates +``` + +#### Using multi-stage builds + +For multi-stage builds where certificates are needed in the final runtime +image, ensure the certificate installation occurs in the final stage. + +```dockerfile +FROM debian:bookworm AS build +WORKDIR /build +RUN apt-get update && apt-get install -y \ + build-essential \ + cmake \ + curl \ + git +RUN --mount=target=. cmake -B output/ + +FROM debian:bookworm-slim AS final +ADD --checksum=sha256:24454f830cdb571e2c4ad15481119c43b3cafd48dd869a9b2945d1036d1dc68d \ + https://artifacts.example/certs/zscaler-root-ca.crt /usr/local/share/ca-certificates/zscaler-root-ca.crt +RUN apt-get update && \ + apt-get install -y ca-certificates && \ + update-ca-certificates +WORKDIR /app +COPY --from=build /build/output/bin . +ENTRYPOINT ["/app/bin"] +``` + +## Conclusion + +Embedding the Zscaler root certificate directly into your Docker images ensures +that containers run smoothly within Zscaler-proxied environments.

The default value is `8080`. - -The application is stateless. - -The complete source code for the application is on GitHub: [github.com/docker/docker-gs-ping](https://github.com/docker/docker-gs-ping). You are encouraged to fork it and experiment with it as much as you like. - -To continue, clone the application repository to your local machine: - -```console -$ git clone https://github.com/docker/docker-gs-ping -``` - -The application's `main.go` file is straightforward, if you are familiar with Go: - - -```go -package main - -import ( - "net/http" - "os" - - "github.com/labstack/echo/v4" - "github.com/labstack/echo/v4/middleware" -) - -func main() { - - e := echo.New() - - e.Use(middleware.Logger()) - e.Use(middleware.Recover()) - - e.GET("/", func(c echo.Context) error { - return c.HTML(http.StatusOK, "Hello, Docker! <3") - }) - - e.GET("/health", func(c echo.Context) error { - return c.JSON(http.StatusOK, struct{ Status string }{Status: "OK"}) - }) - - httpPort := os.Getenv("PORT") - if httpPort == "" { - httpPort = "8080" - } - - e.Logger.Fatal(e.Start(":" + httpPort)) -} - -// Simple implementation of an integer minimum -// Adapted from: https://gobyexample.com/testing-and-benchmarking -func IntMin(a, b int) int { - if a < b { - return a - } - return b -} -``` - -## Create a Dockerfile for the application - -To build a container image with Docker, a `Dockerfile` with build instructions is required. - -Begin your `Dockerfile` with the (optional) parser directive line that instructs BuildKit to -interpret your file according to the grammar rules for the specified version of the syntax. - -You then tell Docker what base image you would like to use for your application: - -```dockerfile -# syntax=docker/dockerfile:1 - -FROM golang:1.19 -``` - -Docker images can be inherited from other images. Therefore, instead of creating -your own base image from scratch, you can use the official Go image that already -has all necessary tools and libraries to compile and run a Go application. - -> **Note** -> -> If you are curious about creating your own base images, you can check out the following section of this guide: [creating base images](../../build/building/base-images.md#create-a-base-image). -> Note, however, that this isn't necessary to continue with your task at hand. - -Now that you have defined the base image for your upcoming container image, you -can begin building on top of it. - -To make things easier when running the rest of your commands, create a directory -inside the image that you're building. This also instructs Docker to use this -directory as the default destination for all subsequent commands. This way you -don't have to type out full file paths in the `Dockerfile`, the relative paths -will be based on this directory. - -```dockerfile -WORKDIR /app -``` - -Usually the very first thing you do once you’ve downloaded a project written in -Go is to install the modules necessary to compile it. Note, that the base image -has the toolchain already, but your source code isn't in it yet. - -So before you can run `go mod download` inside your image, you need to get your -`go.mod` and `go.sum` files copied into it. Use the `COPY` command to do this. - -In its simplest form, the `COPY` command takes two parameters. The first -parameter tells Docker what files you want to copy into the image. The last -parameter tells Docker where you want that file to be copied to. - -Copy the `go.mod` and `go.sum` file into your project directory `/app` which, -owing to your use of `WORKDIR`, is the current directory (`./`) inside the -image. Unlike some modern shells that appear to be indifferent to the use of -trailing slash (`/`), and can figure out what the user meant (most of the time), -Docker's `COPY` command is quite sensitive in its interpretation of the trailing -slash. - -```dockerfile -COPY go.mod go.sum ./ -``` - -> **Note** -> -> If you'd like to familiarize yourself with the trailing slash treatment by the -> `COPY` command, see [Dockerfile -> reference](../../reference/dockerfile.md#copy). This trailing slash can -> cause issues in more ways than you can imagine. - -Now that you have the module files inside the Docker image that you are -building, you can use the `RUN` command to run the command `go mod download` -there as well. This works exactly the same as if you were running `go` locally -on your machine, but this time these Go modules will be installed into a -directory inside the image. - -```dockerfile -RUN go mod download -``` - -At this point, you have a Go toolchain version 1.19.x and all your Go -dependencies installed inside the image. - -The next thing you need to do is to copy your source code into the image. You’ll -use the `COPY` command just like you did with your module files before. - -```dockerfile -COPY *.go ./ -``` - -This `COPY` command uses a wildcard to copy all files with `.go` extension -located in the current directory on the host (the directory where the `Dockerfile` -is located) into the current directory inside the image. - -Now, to compile your application, use the familiar `RUN` command: - -```dockerfile -RUN CGO_ENABLED=0 GOOS=linux go build -o /docker-gs-ping -``` - -This should be familiar. The result of that command will be a static application -binary named `docker-gs-ping` and located in the root of the filesystem of the -image that you are building. You could have put the binary into any other place -you desire inside that image, the root directory has no special meaning in this -regard. It's just convenient to use it to keep the file paths short for improved -readability. - -Now, all that is left to do is to tell Docker what command to run when your -image is used to start a container. - -You do this with the `CMD` command: - -```dockerfile -CMD ["/docker-gs-ping"] -``` - -Here's the complete `Dockerfile`: - -```dockerfile -# syntax=docker/dockerfile:1 - -FROM golang:1.19 - -# Set destination for COPY -WORKDIR /app - -# Download Go modules -COPY go.mod go.sum ./ -RUN go mod download - -# Copy the source code. Note the slash at the end, as explained in -# https://docs.docker.com/reference/dockerfile/#copy -COPY *.go ./ - -# Build -RUN CGO_ENABLED=0 GOOS=linux go build -o /docker-gs-ping - -# Optional: -# To bind to a TCP port, runtime parameters must be supplied to the docker command. -# But we can document in the Dockerfile what ports -# the application is going to listen on by default. -# https://docs.docker.com/reference/dockerfile/#expose -EXPOSE 8080 - -# Run -CMD ["/docker-gs-ping"] -``` - -The `Dockerfile` may also contain comments. They always begin with a `#` symbol, -and must be at the beginning of a line. Comments are there for your convenience -to allow documenting your `Dockerfile`. - -There is also a concept of Dockerfile directives, such as the `syntax` directive -you added. The directives must always be at the very top of the `Dockerfile`, so -when adding comments, make sure that the comments follow after any directives -that you may have used: - -```dockerfile -# syntax=docker/dockerfile:1 -# A sample microservice in Go packaged into a container image. - -FROM golang:1.19 - -# ... -``` - -## Build the image - -Now that you've created your `Dockerfile`, build an image from it. The `docker -build` command creates Docker images from the `Dockerfile` and a context. A -build context is the set of files located in the specified path or URL. The -Docker build process can access any of the files located in the context. - -The build command optionally takes a `--tag` flag. This flag is used to label -the image with a string value, which is easy for humans to read and recognise. -If you don't pass a `--tag`, Docker will use `latest` as the default value. - -Build your first Docker image. - -```console -$ docker build --tag docker-gs-ping . -``` - -The build process will print some diagnostic messages as it goes through the build steps. -The following is just an example of what these messages may look like. - -```console -[+] Building 2.2s (15/15) FINISHED - => [internal] load build definition from Dockerfile 0.0s - => => transferring dockerfile: 701B 0.0s - => [internal] load .dockerignore 0.0s - => => transferring context: 2B 0.0s - => resolve image config for docker.io/docker/dockerfile:1 1.1s - => CACHED docker-image://docker.io/docker/dockerfile:1@sha256:39b85bbfa7536a5feceb7372a0817649ecb2724562a38360f4d6a7782a409b14 0.0s - => [internal] load build definition from Dockerfile 0.0s - => [internal] load .dockerignore 0.0s - => [internal] load metadata for docker.io/library/golang:1.19 0.7s - => [1/6] FROM docker.io/library/golang:1.19@sha256:5d947843dde82ba1df5ac1b2ebb70b203d106f0423bf5183df3dc96f6bc5a705 0.0s - => [internal] load build context 0.0s - => => transferring context: 6.08kB 0.0s - => CACHED [2/6] WORKDIR /app 0.0s - => CACHED [3/6] COPY go.mod go.sum ./ 0.0s - => CACHED [4/6] RUN go mod download 0.0s - => CACHED [5/6] COPY *.go ./ 0.0s - => CACHED [6/6] RUN CGO_ENABLED=0 GOOS=linux go build -o /docker-gs-ping 0.0s - => exporting to image 0.0s - => => exporting layers 0.0s - => => writing image sha256:ede8ff889a0d9bc33f7a8da0673763c887a258eb53837dd52445cdca7b7df7e3 0.0s - => => naming to docker.io/library/docker-gs-ping 0.0s -``` - -Your exact output will vary, but provided there aren't any errors, you should -see the word `FINISHED` in the first line of output. This means Docker has -successfully built your image named `docker-gs-ping`. - -## View local images - -To see the list of images you have on your local machine, you have two options. -One is to use the CLI and the other is to use [Docker -Desktop](../../desktop/index.md). Since you're currently working in the -terminal, take a look at listing images with the CLI. - -To list images, run the `docker image ls`command (or the `docker images` shorthand): - -```console -$ docker image ls - -REPOSITORY TAG IMAGE ID CREATED SIZE -docker-gs-ping latest 7f153fbcc0a8 2 minutes ago 1.11GB -... -``` - -Your exact output may vary, but you should see the `docker-gs-ping` image with -the `latest` tag. Because you didn't specify a custom tag when you built your -image, Docker assumed that the tag would be `latest`, which is a special value. - -## Tag images - -An image name is made up of slash-separated name components. Name components may -contain lowercase letters, digits, and separators. A separator is defined as a -period, one or two underscores, or one or more dashes. A name component may not -start or end with a separator. - -An image is made up of a manifest and a list of layers. In simple terms, a tag -points to a combination of these artifacts. You can have multiple tags for the -image and, in fact, most images have multiple tags. Create a second tag -for the image you built and take a look at its layers. - -Use the `docker image tag` (or `docker tag` shorthand) command to create a new -tag for your image. This command takes two arguments; the first argument is the -source image, and the second is the new tag to create. The following command -creates a new `docker-gs-ping:v1.0` tag for the `docker-gs-ping:latest` you -built: - -```console -$ docker image tag docker-gs-ping:latest docker-gs-ping:v1.0 -``` - -The Docker `tag` command creates a new tag for the image. It doesn't create a -new image. The tag points to the same image and is just another way to reference -the image. - -Now run the `docker image ls` command again to see the updated list of local -images: - -```console -$ docker image ls - -REPOSITORY TAG IMAGE ID CREATED SIZE -docker-gs-ping latest 7f153fbcc0a8 6 minutes ago 1.11GB -docker-gs-ping v1.0 7f153fbcc0a8 6 minutes ago 1.11GB -... -``` - -You can see that you have two images that start with `docker-gs-ping`. You know -they're the same image because if you look at the `IMAGE ID` column, you can -see that the values are the same for the two images. This value is a unique -identifier Docker uses internally to identify the image. - -Remove the tag that you just created. To do this, you’ll use the -`docker image rm` command, or the shorthand `docker rmi` (which stands for -"remove image"): - -```console -$ docker image rm docker-gs-ping:v1.0 -Untagged: docker-gs-ping:v1.0 -``` - -Notice that the response from Docker tells you that the image hasn't been -removed but only untagged. - -Verify this by running the following command: - -```console -$ docker image ls -``` - -You will see that the tag `v1.0` is no longer in the list of images kept by your Docker instance. - -```text -REPOSITORY TAG IMAGE ID CREATED SIZE -docker-gs-ping latest 7f153fbcc0a8 7 minutes ago 1.11GB -... -``` - -The tag `v1.0` has been removed but you still have the `docker-gs-ping:latest` -tag available on your machine, so the image is there. - -## Multi-stage builds - -You may have noticed that your `docker-gs-ping` image weighs in at over a -gigabyte, which is a lot for a tiny compiled Go application. You may also be -wondering what happened to the full suite of Go tools, including the compiler, -after you had built your image. - -The answer is that the full toolchain is still there, in the container image. -Not only this is inconvenient because of the large file size, but it may also -present a security risk when the container is deployed. - -These two issues can be solved by using [multi-stage builds](../../build/building/multi-stage.md). - -In a nutshell, a multi-stage build can carry over the artifacts from one build stage into another, -and every build stage can be instantiated from a different base image. - -Thus, in the following example, you are going to use a full-scale official Go -image to build your application. Then you'll copy the application binary into -another image whose base is very lean and doesn't include the Go toolchain or -other optional components. - -The `Dockerfile.multistage` in the sample application's repository has the -following content: - - -```dockerfile -# syntax=docker/dockerfile:1 - -# Build the application from source -FROM golang:1.19 AS build-stage - -WORKDIR /app - -COPY go.mod go.sum ./ -RUN go mod download - -COPY *.go ./ - -RUN CGO_ENABLED=0 GOOS=linux go build -o /docker-gs-ping - -# Run the tests in the container -FROM build-stage AS run-test-stage -RUN go test -v ./... - -# Deploy the application binary into a lean image -FROM gcr.io/distroless/base-debian11 AS build-release-stage - -WORKDIR / - -COPY --from=build-stage /docker-gs-ping /docker-gs-ping - -EXPOSE 8080 - -USER nonroot:nonroot - -ENTRYPOINT ["/docker-gs-ping"] -``` - - -Since you have two Dockerfiles now, you have to tell Docker what Dockerfile -you'd like to use to build the image. Tag the new image with `multistage`. This -tag (like any other, apart from `latest`) has no special meaning for Docker, -it's just something you chose. - -```console -$ docker build -t docker-gs-ping:multistage -f Dockerfile.multistage . -``` - -Comparing the sizes of `docker-gs-ping:multistage` and `docker-gs-ping:latest` -you see a few orders-of-magnitude difference. - -```console -$ docker image ls -REPOSITORY TAG IMAGE ID CREATED SIZE -docker-gs-ping multistage e3fdde09f172 About a minute ago 28.1MB -docker-gs-ping latest 336a3f164d0f About an hour ago 1.11GB -``` - -This is so because the ["distroless"](https://github.com/GoogleContainerTools/distroless) -base image that you have used in the second stage of the build is very barebones and is designed for lean deployments of static binaries. - -There's much more to multi-stage builds, including the possibility of multi-architecture builds, -so feel free to check out [multi-stage builds](../../build/building/multi-stage.md).

So, if you are familiar with Postgres, don't be surprised if you see some familiar environment variables names. The Go modules that work with Postgres, such as [pgx](https://pkg.go.dev/github.com/jackc/pgx), [pq](https://pkg.go.dev/github.com/lib/pq), [GORM](https://gorm.io/index.html), and [upper/db](https://upper.io/v4/) also work with CockroachDB. - -For more information on the relation between Go and CockroachDB, refer to the [CockroachDB documentation](https://www.cockroachlabs.com/docs/v20.2/build-a-go-app-with-cockroachdb.html), although this isn't necessary to continue with the present guide. - -### Storage - -The point of a database is to have a persistent store of data. [Volumes](../../storage/volumes.md) are the preferred mechanism for persisting data generated by and used by Docker containers. Thus, before you start CockroachDB, create the volume for it. - -To create a managed volume, run : - -```console -$ docker volume create roach -roach -``` - -You can view the list of all managed volumes in your Docker instance with the following command: - -```console -$ docker volume list -DRIVER VOLUME NAME -local roach -``` - -### Networking - -The example application and the database engine are going to talk to one another over the network. There are different kinds of network configuration possible, and you're going to use what's called a user-defined bridge network. It is going to provide you with a DNS lookup service so that you can refer to your database engine container by its hostname. - -The following command creates a new bridge network named `mynet`: - -```console -$ docker network create -d bridge mynet -51344edd6430b5acd121822cacc99f8bc39be63dd125a3b3cd517b6485ab7709 -``` - -As it was the case with the managed volumes, there is a command to list all networks set up in your Docker instance: - -```console -$ docker network list -NETWORK ID NAME DRIVER SCOPE -0ac2b1819fa4 bridge bridge local -51344edd6430 mynet bridge local -daed20bbecce host host local -6aee44f40a39 none null local -``` - -Your bridge network `mynet` has been created successfully. The other three networks, named `bridge`, `host`, and `none` are the default networks and they had been created by the Docker itself. While it's not relevant to this guide, you can learn more about Docker networking in the [networking overview](../../network/index.md) section. - -### Choose good names for volumes and networks - -As the saying goes, there are only two hard things in Computer Science: cache invalidation and naming things. And off-by-one errors. - -When choosing a name for a network or a managed volume, it's best to choose a name that's indicative of the intended purpose. This guide aims for brevity, so it used short, generic names. - -### Start the database engine - -Now that the housekeeping chores are done, you can run CockroachDB in a container and attach it to the volume and network you had just created. When you run the following command, Docker will pull the image from Docker Hub and run it for you locally: - -```console -$ docker run -d \ - --name roach \ - --hostname db \ - --network mynet \ - -p 26257:26257 \ - -p 8080:8080 \ - -v roach:/cockroach/cockroach-data \ - cockroachdb/cockroach:latest-v20.1 start-single-node \ - --insecure - -# ... output omitted ... -``` - -Notice a clever use of the tag `latest-v20.1` to make sure that you're pulling the latest patch version of 20.1. The diversity of available tags depend on the image maintainer. Here, your intent was to have the latest patched version of CockroachDB while not straying too far away from the known working version as the time goes by. To see the tags available for the CockroachDB image, you can go to the [CockroachDB page on Docker Hub](https://hub.docker.com/r/cockroachdb/cockroach/tags). - -### Configure the database engine - -Now that the database engine is live, there is some configuration to do before your application can begin using it. Fortunately, it's not a lot. You must: - -1. Create a blank database. -2. Register a new user account with the database engine. -3. Grant that new user access rights to the database. - -You can do that with the help of CockroachDB built-in SQL shell. To start the SQL shell in the same container where the database engine is running, type: - -```console -$ docker exec -it roach ./cockroach sql --insecure -``` - -1. In the SQL shell, create the database that the example application is going to use: - - ```sql - CREATE DATABASE mydb; - ``` - -2. Register a new SQL user account with the database engine. Use the username `totoro`. - - ```sql - CREATE USER totoro; - ``` - -3. Give the new user the necessary permissions: - - ```sql - GRANT ALL ON DATABASE mydb TO totoro; - ``` - -4. Type `quit` to exit the shell. - -The following is an example of interaction with the SQL shell. - - -```console -$ sudo docker exec -it roach ./cockroach sql --insecure -# -# Welcome to the CockroachDB SQL shell. -# All statements must be terminated by a semicolon. -# To exit, type: \q. -# -# Server version: CockroachDB CCL v20.1.15 (x86_64-unknown-linux-gnu, built 2021/04/26 16:11:58, go1.13.9) (same version as client) -# Cluster ID: 7f43a490-ccd6-4c2a-9534-21f393ca80ce -# -# Enter \? for a brief introduction. -# -root@:26257/defaultdb> CREATE DATABASE mydb; -CREATE DATABASE - -Time: 22.985478ms - -root@:26257/defaultdb> CREATE USER totoro; -CREATE ROLE - -Time: 13.921659ms - -root@:26257/defaultdb> GRANT ALL ON DATABASE mydb TO totoro; -GRANT - -Time: 14.217559ms - -root@:26257/defaultdb> quit -oliver@hki:~$ -``` - - -### Meet the example application - -Now that you have started and configured the database engine, you can switch your attention to the application. - -The example application for this module is an extended version of `docker-gs-ping` application you've used in the previous modules. You have two options: - -* You can update your local copy of `docker-gs-ping` to match the new extended version presented in this chapter; or -* You can clone the [docker/docker-gs-ping-dev](https://github.com/docker/docker-gs-ping-dev) repository. This latter approach is recommended. - -To checkout the example application, run: - -```console -$ git clone https://github.com/docker/docker-gs-ping-dev.git -# ... output omitted ... -``` - -The application's `main.go` now includes database initialization code, as well as the code to implement a new business requirement: - -* An HTTP `POST` request to `/send` containing a `{ "value" : string }` JSON must save the value to the database. - -You also have an update for another business requirement. The requirement was: - -* The application responds with a text message containing a heart symbol ("`<3`") on requests to `/`. - -And now it's going to be: - -* The application responds with the string containing the count of messages stored in the database, enclosed in the parentheses. - - Example output: `Hello, Docker! (7)` - -The full source code listing of `main.go` follows. - -```go -package main - -import ( - "context" - "database/sql" - "fmt" - "log" - "net/http" - "os" - - "github.com/cenkalti/backoff/v4" - "github.com/cockroachdb/cockroach-go/v2/crdb" - "github.com/labstack/echo/v4" - "github.com/labstack/echo/v4/middleware" -) - -func main() { - - e := echo.New() - - e.Use(middleware.Logger()) - e.Use(middleware.Recover()) - - db, err := initStore() - if err != nil { - log.Fatalf("failed to initialise the store: %s", err) - } - defer db.Close() - - e.GET("/", func(c echo.Context) error { - return rootHandler(db, c) - }) - - e.GET("/ping", func(c echo.Context) error { - return c.JSON(http.StatusOK, struct{ Status string }{Status: "OK"}) - }) - - e.POST("/send", func(c echo.Context) error { - return sendHandler(db, c) - }) - - httpPort := os.Getenv("HTTP_PORT") - if httpPort == "" { - httpPort = "8080" - } - - e.Logger.Fatal(e.Start(":" + httpPort)) -} - -type Message struct { - Value string `json:"value"` -} - -func initStore() (*sql.DB, error) { - - pgConnString := fmt.Sprintf("host=%s port=%s dbname=%s user=%s password=%s sslmode=disable", - os.Getenv("PGHOST"), - os.Getenv("PGPORT"), - os.Getenv("PGDATABASE"), - os.Getenv("PGUSER"), - os.Getenv("PGPASSWORD"), - ) - - var ( - db *sql.DB - err error - ) - openDB := func() error { - db, err = sql.Open("postgres", pgConnString) - return err - } - - err = backoff.Retry(openDB, backoff.NewExponentialBackOff()) - if err != nil { - return nil, err - } - - if _, err := db.Exec( - "CREATE TABLE IF NOT EXISTS message (value TEXT PRIMARY KEY)"); err != nil { - return nil, err - } - - return db, nil -} - -func rootHandler(db *sql.DB, c echo.Context) error { - r, err := countRecords(db) - if err != nil { - return c.HTML(http.StatusInternalServerError, err.Error()) - } - return c.HTML(http.StatusOK, fmt.Sprintf("Hello, Docker!

It uses the official Docker Go image to build the application and then builds the final image by placing the compiled binary into the much slimmer, distroless image. - -Regardless of whether you had updated the old example application, or checked out the new one, this new Docker image has to be built to reflect the changes to the application source code. - -### Build the application - -You can build the image with the familiar `build` command: - -```console -$ docker build --tag docker-gs-ping-roach . -``` - -### Run the application - -Now, run your container. This time you'll need to set some environment variables so that your application knows how to access the database. For now, you’ll do this right in the `docker run` command. Later you'll see a more convenient method with Docker Compose. - -> **Note** -> -> Since you're running your CockroachDB cluster in insecure mode, the value for the password can be anything. -> -> In production, don't run in insecure mode. - -```console -$ docker run -it --rm -d \ - --network mynet \ - --name rest-server \ - -p 80:8080 \ - -e PGUSER=totoro \ - -e PGPASSWORD=myfriend \ - -e PGHOST=db \ - -e PGPORT=26257 \ - -e PGDATABASE=mydb \ - docker-gs-ping-roach -``` - -There are a few points to note about this command. - -* You map container port `8080` to host port `80` this time. Thus, for `GET` requests you can get away with literally `curl localhost`: - - ```console - $ curl localhost - Hello, Docker! (0) - ``` - - Or, if you prefer, a proper URL would work just as well: - - ```console - $ curl http://localhost/ - Hello, Docker! (0) - ``` - -* The total number of stored messages is `0` for now. This is fine, because you haven't posted anything to your application yet. -* You refer to the database container by its hostname, which is `db`. This is why you had `--hostname db` when you started the database container. - -* The actual password doesn't matter, but it must be set to something to avoid confusing the example application. -* The container you've just run is named `rest-server`. These names are useful for managing the container lifecycle: - - ```console - # Don't do this just yet, it's only an example: - $ docker container rm --force rest-server - ``` - -### Test the application - -In the previous section, you've already tested querying your application with `GET` and it returned zero for the stored message counter. Now, post some messages to it: - -```console -$ curl --request POST \ - --url http://localhost/send \ - --header 'content-type: application/json' \ - --data '{"value": "Hello, Docker!"}' -``` - -The application responds with the contents of the message, which means it has been saved in the database: - -```json -{"value":"Hello, Docker!"} -``` - -Send another message: - -```console -$ curl --request POST \ - --url http://localhost/send \ - --header 'content-type: application/json' \ - --data '{"value": "Hello, Oliver!"}' -``` - -And again, you get the value of the message back: - -```json -{"value":"Hello, Oliver!"} -``` - -Run curl and see what the message counter says: - -```console -$ curl localhost -Hello, Docker! (2) -``` - -In this example, you sent two messages and the database kept them. Or has it? Stop and remove all your containers, but not the volumes, and try again. - -First, stop the containers: - -```console -$ docker container stop rest-server roach -rest-server -roach -``` - -Then, remove them: - -```console -$ docker container rm rest-server roach -rest-server -roach -``` - -Verify that they're gone: - -```console -$ docker container list --all -CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES -``` - -And start them again, database first: - -```console -$ docker run -d \ - --name roach \ - --hostname db \ - --network mynet \ - -p 26257:26257 \ - -p 8080:8080 \ - -v roach:/cockroach/cockroach-data \ - cockroachdb/cockroach:latest-v20.1 start-single-node \ - --insecure -``` - -And the service next: - -```console -$ docker run -it --rm -d \ - --network mynet \ - --name rest-server \ - -p 80:8080 \ - -e PGUSER=totoro \ - -e PGPASSWORD=myfriend \ - -e PGHOST=db \ - -e PGPORT=26257 \ - -e PGDATABASE=mydb \ - docker-gs-ping-roach -``` - -Lastly, query your service: - -```console -$ curl localhost -Hello, Docker! (2) -``` - -Great! The count of records from the database is correct although you haven't only stopped the containers, but you've also removed them before starting new instances. The difference is in the managed volume for CockroachDB, which you reused. The new CockroachDB container has read the database files from the disk, just as it normally would if it were running outside the container. - -### Wind down everything - -Remember, that you're running CockroachDB in insecure mode. Now that you've built and tested your application, it's time to wind everything down before moving on. You can list the containers that you are running with the `list` command: - -```console -$ docker container list -``` - -Now that you know the container IDs, you can use `docker container stop` and `docker container rm`, as demonstrated in the previous modules. - -Stop the CockroachDB and `docker-gs-ping-roach` containers before moving on. - -## Better productivity with Docker Compose - -At this point, you might be wondering if there is a way to avoid having to deal with long lists of arguments to the `docker` command. The toy example you used in this series requires five environment variables to define the connection to the database. A real application might need many, many more. Then there is also a question of dependencies. Ideally, you want to make sure that the database is started before your application is run. And spinning up the database instance may require another Docker command with many options. But there is a better way to orchestrate these deployments for local development purposes. - -In this section, you'll create a Docker Compose file to start your `docker-gs-ping-roach` application and CockroachDB database engine with a single command. - -### Configure Docker Compose - -In your application's directory, create a new text file named `docker-compose.yml` with the following content. - - -```yaml -version: '3.8' - -services: - docker-gs-ping-roach: - depends_on: - - roach - build: - context: . - container_name: rest-server - hostname: rest-server - networks: - - mynet - ports: - - 80:8080 - environment: - - PGUSER=${PGUSER:-totoro} - - PGPASSWORD=${PGPASSWORD:?database password not set} - - PGHOST=${PGHOST:-db} - - PGPORT=${PGPORT:-26257} - - PGDATABASE=${PGDATABASE:-mydb} - deploy: - restart_policy: - condition: on-failure - roach: - image: cockroachdb/cockroach:latest-v20.1 - container_name: roach - hostname: db - networks: - - mynet - ports: - - 26257:26257 - - 8080:8080 - volumes: - - roach:/cockroach/cockroach-data - command: start-single-node --insecure - -volumes: - roach: - -networks: - mynet: - driver: bridge -``` - - -This Docker Compose configuration is super convenient as you don't have to type all the parameters to pass to the `docker run` command. You can declaratively do that in the Docker Compose file. The [Docker Compose documentation pages](../../compose/index.md) are quite extensive and include a full reference for the Docker Compose file format. - -### The `.env` file - -Docker Compose will automatically read environment variables from a `.env` file if it's available. Since your Compose file requires `PGPASSWORD` to be set, add the following content to the `.env` file: - -```bash -PGPASSWORD=whatever -``` - -The exact value doesn't really matter for this example, because you run CockroachDB in insecure mode. Make sure you set the variable to some value to avoid getting an error. - -### Merging Compose files - -The file name `docker-compose.yml` is the default file name which `docker compose` command recognizes if no `-f` flag is provided. This means you can have multiple Docker Compose files if your environment has such requirements. Furthermore, Docker Compose files are... composable (pun intended), so multiple files can be specified on the command line to merge parts of the configuration together. The following list is just a few examples of scenarios where such a feature would be very useful: - -* Using a bind mount for the source code for local development but not when running the CI tests; -* Switching between using a pre-built image for the frontend for some API application vs creating a bind mount for source code; -* Adding additional services for integration testing; -* And many more... - -You aren't going to cover any of these advanced use cases here. - -### Variable substitution in Docker Compose - -One of the really cool features of Docker Compose is [variable substitution](../../compose/compose-file/12-interpolation.md). You can see some examples in the Compose file, `environment` section. By means of an example: - -* `PGUSER=${PGUSER:-totoro}` means that inside the container, the environment variable `PGUSER` shall be set to the same value as it has on the host machine where Docker Compose is run. If there is no environment variable with this name on the host machine, the variable inside the container gets the default value of `totoro`. -* `PGPASSWORD=${PGPASSWORD:?database password not set}` means that if the environment variable `PGPASSWORD` isn't set on the host, Docker Compose will display an error. This is OK, because you don't want to hard-code default values for the password. You set the password value in the `.env` file, which is local to your machine. It is always a good idea to add `.env` to `.gitignore` to prevent the secrets being checked into the version control. - -Other ways of dealing with undefined or empty values exist, as documented in the [variable substitution](../../compose/compose-file/12-interpolation.md) section of the Docker documentation. - -### Validating Docker Compose configuration - -Before you apply changes made to a Compose configuration file, there is an opportunity to validate the content of the configuration file with the following command: - -```console -$ docker compose config -``` - -When this command is run, Docker Compose reads the file `docker-compose.yml`, parses it into a data structure in memory, validates where possible, and prints back the reconstruction of that configuration file from its internal representation. If this isn't possible due to errors, Docker prints an error message instead. - -### Build and run the application using Docker Compose - -Start your application and confirm that it's running. - -```console -$ docker compose up --build -``` - -You passed the `--build` flag so Docker will compile your image and then start it. - -> **Note** -> -> Docker Compose is a useful tool, but it has its own quirks. For example, no rebuild is triggered on the update to the source code unless the `--build` flag is provided. It is a very common pitfall to edit one's source code, and forget to use the `--build` flag when running `docker compose up`. - -Since your set-up is now run by Docker Compose, it has assigned it a project name, so you get a new volume for your CockroachDB instance. This means that your application will fail to connect to the database, because the database doesn't exist in this new volume. The terminal displays an authentication error for the database: - -```text -# ... omitted output ... -rest-server | 2021/05/10 00:54:25 failed to initialise the store: pq: password authentication failed for user totoro -roach | * -roach | * INFO: Replication was disabled for this cluster. -roach | * When/if adding nodes in the future, update zone configurations to increase the replication factor. -roach | * -roach | CockroachDB node starting at 2021-05-10 00:54:26.398177 +0000 UTC (took 3.0s) -roach | build: CCL v20.1.15 @ 2021/04/26 16:11:58 (go1.13.9) -roach | webui: http://db:8080 -roach | sql: postgresql://root@db:26257?sslmode=disable -roach | RPC client flags: /cockroach/cockroach --host=db:26257 --insecure -roach | logs: /cockroach/cockroach-data/logs -roach | temp dir: /cockroach/cockroach-data/cockroach-temp349434348 -roach | external I/O path: /cockroach/cockroach-data/extern -roach | store[0]: path=/cockroach/cockroach-data -roach | storage engine: rocksdb -roach | status: initialized new cluster -roach | clusterID: b7b1cb93-558f-4058-b77e-8a4ddb329a88 -roach | nodeID: 1 -rest-server exited with code 0 -rest-server | 2021/05/10 00:54:25 failed to initialise the store: pq: password authentication failed for user totoro -rest-server | 2021/05/10 00:54:26 failed to initialise the store: pq: password authentication failed for user totoro -rest-server | 2021/05/10 00:54:29 failed to initialise the store: pq: password authentication failed for user totoro -rest-server | 2021/05/10 00:54:25 failed to initialise the store: pq: password authentication failed for user totoro -rest-server | 2021/05/10 00:54:26 failed to initialise the store: pq: password authentication failed for user totoro -rest-server | 2021/05/10 00:54:29 failed to initialise the store: pq: password authentication failed for user totoro -rest-server exited with code 1 -# ... omitted output ... -``` - -Because of the way you set up your deployment using `restart_policy`, the failing container is being restarted every 20 seconds. So, in order to fix the problem, you need to log in to the database engine and create the user. You've done it before in [Configure the database engine](#configure-the-database-engine). - -This isn't a big deal. All you have to do is to connect to CockroachDB instance and run the three SQL commands to create the database and the user, as described in [Configure the database engine](#configure-the-database-engine). - -So, log in to the database engine from another terminal: - -```console -$ docker exec -it roach ./cockroach sql --insecure -``` - -And run the same commands as before to create the database `mydb`, the user `totoro`, and to grant that user necessary permissions. Once you do that (and the example application container is automatically restarts), the `rest-service` stops failing and restarting and the console goes quiet. - -It would have been possible to connect the volume that you had previously used, but for the purposes of this example it's more trouble than it's worth and it also provided an opportunity to show how to introduce resilience into your deployment via the `restart_policy` Compose file feature. - -### Testing the application - -Now, test your API endpoint. In the new terminal, run the following command: - -```console -$ curl http://localhost/ -``` - -You should receive the following response: - -```json -Hello, Docker! (0) -``` - -### Shutting down - -To stop the containers started by Docker Compose, press `ctrl+c` in the terminal where you ran `docker compose up`. To remove those containers after they've been stopped, run `docker compose down`. - -### Detached mode - -You can run containers started by the `docker compose` command in detached mode, just as you would with the `docker` command, by using the `-d` flag. - -To start the stack, defined by the Compose file in detached mode, run: - -```console -$ docker compose up --build -d -``` - -Then, you can use `docker compose stop` to stop the containers and `docker compose down` to remove them. - -## Further exploration - -You can run `docker compose` to see what other commands are available. - -## Wrap up - -There are some tangential, yet interesting points that were purposefully not covered in this chapter. For the more adventurous reader, this section offers some pointers for further study. - -### Persistent storage - -A managed volume isn't the only way to provide your container with persistent storage. It is highly recommended to get acquainted with available storage options and their use cases, covered in [Manage data in Docker](../../storage/_index.md). - -### CockroachDB clusters - -You ran a single instance of CockroachDB, which was enough for this example. But, it's possible to run a CockroachDB cluster, which is made of multiple instances of CockroachDB, each instance running in its own container. Since CockroachDB engine is distributed by design, it would have taken surprisingly little change to your procedure to run a cluster with multiple nodes. - -Such distributed set-up offers interesting possibilities, such as applying Chaos Engineering techniques to simulate parts of the cluster failing and evaluating your application's ability to cope with such failures. - -If you are interested in experimenting with CockroachDB clusters, check out: - -* [Start a CockroachDB Cluster in Docker](https://www.cockroachlabs.com/docs/v20.2/start-a-local-cluster-in-docker-mac.html) article; and -* Documentation for Docker Compose keywords [`deploy`](../../compose/compose-file/legacy-versions.md) and [`replicas`](../../compose/compose-file/legacy-versions.md). - -### Other databases - -Since you didn't run a cluster of CockroachDB instances, you might be wondering whether you could have used a non-distributed database engine. The answer is 'yes', and if you were to pick a more traditional SQL database, such as [PostgreSQL](https://www.postgresql.org/), the process described in this chapter would have been very similar. - -## Next steps - -In this module, you set up a containerized development environment with your application and the database engine running in different containers. You also wrote a Docker Compose file which links the two containers together and provides for easy starting up and tearing down of the development environment. - -In the next module, you'll take a look at one possible approach to running functional tests in Docker. - -{{< button text="Run your tests" url="run-tests.md" >}} diff --git a/content/language/golang/run-containers.md b/content/language/golang/run-containers.md deleted file mode 100644 index a865a10b0c21..000000000000 --- a/content/language/golang/run-containers.md +++ /dev/null @@ -1,208 +0,0 @@ ---- -title: Run your Go image as a container -keywords: get started, go, golang, run, container -description: Learn how to run the image as a container. -aliases: -- /get-started/golang/run-containers/ ---- - -## Prerequisites - -Work through the steps to containerize a Go application in [Build your Go image](build-images.md). - -## Overview - -In the previous module you created a `Dockerfile` for your example application and then you created your Docker image using the command `docker build`.

The `docker run` command requires one parameter which is the name of the image. - -## Run an image - -Use `docker run` to run the image you built in [Build your Rust image](build-images.md). - -```console -$ docker run docker-rust-image -``` - -After running this command, you’ll notice that you weren't returned to the command prompt.

This means you weren't able to connect to the localhost on port 8000. This is normal because your container is running in isolation which includes networking. Stop the container and restart with port 8000 published on your local network. - -To stop the container, press ctrl-c. This will return you to the terminal prompt. - -To publish a port for your container, you’ll use the `--publish` flag (`-p` for short) on the `docker run` command. The format of the `--publish` command is `[host port]:[container port]`. So, if you wanted to expose port 8000 inside the container to port 3001 outside the container, you would pass `3001:8000` to the `--publish` flag. - -You didn't specify a port when running the application in the container and the default is 8000. If you want your previous request going to port 8000 to work, you can map the host's port 3001 to the container's port 8000: - -```console -$ docker run --publish 3001:8000 docker-rust-image -``` - -Now, rerun the curl command.

Docker can run your container in detached mode or in the background. To do this, you can use the `--detach` or `-d` for short.

You can see the container ID, the image running inside the container, the command that was used to start the container, when it was created, the status, ports that were exposed, and the name of the container. - -You are probably wondering where the name of your container is coming from. Since you didn’t provide a name for the container when you started it, Docker generated a random name. You’ll fix this in a minute, but first you need to stop the container. To stop the container, run the `docker stop` command which does just that, stops the container.

Identify the Docker users in your organization. + - If your organization uses device management software, like MDM or Jamf, + you can use the device management software to help identify Docker users. + See your device management software's documentation for details. You can + identify Docker users by checking if Docker Desktop is installed at the + following location on each user's machine: + - Mac: `/Applications/Docker.app` + - Windows: `C:\Program Files\Docker\Docker` + - Linux: `/opt/docker-desktop` + - If your organization doesn't use device management software or your + users haven't installed Docker Desktop yet, you can survey your users to + identify who is using Docker Desktop. +1. Ask users to update their Docker account's email address to one associated +with your organization's domain, or create a new account with that email. + - To update an account's email address, instruct your users to sign in + to [Docker Hub](https://hub.docker.com), and update the email address to + their email address in your organization's domain. + - To create a new account, instruct your users to + [sign up](https://hub.docker.com/signup) using their email address associated + with your organization's domain. Ensure your users verify their email address. +1. Identify Docker accounts associated with your organization's domain: + - Ask your Docker sales representative or + [contact sales](https://www.docker.com/pricing/contact-sales/) to get a list + of Docker accounts that use an email address in your organization's domain. + +### Step two: Invite owners + +Owners can help you onboard and manage your organization. + +When you create an organization, you are the only owner. It is optional to +add additional owners. + +To add an owner, invite a user and assign them the owner role. For more +details, see [Invite members](/manuals/admin/organization/members.md) and +[Roles and permissions](/manuals/enterprise/security/roles-and-permissions.md). + +### Step three: Invite members + +When you add users to your organization, you gain visibility into their +activity and you can enforce security settings.

To upgrade a Docker Team subscription to a Docker Business +subscription, see [Change your subscription](/manuals/subscription/change.md). + +Use your identity provider (IdP) to manage members and provision them to Docker +automatically via SSO and SCIM. See the following for more details: + + - [Configure SSO](/manuals/enterprise/security/single-sign-on/configure.md) + to authenticate and add members when they sign in to Docker through your + identity provider. + - Optional. + [Enforce SSO](/manuals/enterprise/security/single-sign-on/connect.md) to + ensure that when users sign in to Docker, they must use SSO. + + > [!NOTE] + > + > Enforcing single sign-on (SSO) and enforcing Docker Desktop sign in + are different features.

These aren't +features or configuration options - they're approaches that work well in +practice. + +## Handling large command outputs + +Shell commands that produce large output can overflow your agent's context +window. Validation tools, test suites, and build logs often generate thousands +of lines. If you capture this output directly, it consumes all available context +and the agent fails. + +The solution: redirect output to a file, then read the file. The Read tool +automatically truncates large files to 2000 lines, and your agent can navigate +through it if needed. + +**Don't do this:** + +```yaml +reviewer: + instruction: | + Run validation: `docker buildx bake validate` + Check the output for errors. + toolsets: + - type: shell +``` + +The validation output goes directly into context.

The agent reads what it needs using the +filesystem toolset. + +## Structuring agent teams + +A single agent handling multiple responsibilities makes instructions complex and +behavior unpredictable. Breaking work across specialized agents produces better +results. + +The coordinator pattern works well: a root agent understands the overall task +and delegates to specialists. Each specialist focuses on one thing. + +**Example: Documentation writing team** + +```yaml +agents: + root: + description: Technical writing coordinator + instruction: | + Coordinate documentation work: + 1. Delegate to writer for content creation + 2. Delegate to editor for formatting polish + 3. Delegate to reviewer for validation + 4.

The writer doesn't worry about line +wrapping. The editor doesn't generate content. The reviewer just runs tools. + +This example uses `sub_agents` where root delegates discrete tasks and gets +results back. The root agent maintains control and coordinates all work.

If files change, cagent detects this and +re-indexes only what changed, keeping your knowledge base up to date without +manual intervention. + +## Retrieval strategies + +Different content requires different retrieval approaches. cagent supports +three strategies, each optimized for different use cases. The defaults work +well, but understanding the trade-offs helps you choose the right approach. + +### Semantic search (chunked-embeddings) + +Converts text to vectors that represent meaning, enabling search by concept +rather than exact words: + +```yaml +strategies: + - type: chunked-embeddings + embedding_model: openai/text-embedding-3-small + vector_dimensions: 1536 + database: ./docs.db + chunking: + size: 1000 + overlap: 100 +``` + +During indexing, documents are split into chunks and each chunk is converted +to a 1536-dimensional vector by the embedding model. These vectors are +essentially coordinates in a high-dimensional space where similar concepts are +positioned close together. + +When you search for "how do I authenticate users?", your query becomes a vector +and the database finds chunks with nearby vectors using cosine similarity +(measuring the angle between vectors). The embedding model learned that +"authentication," "auth," and "login" are related concepts, so searching for +one finds the others. + +Example: The query "how do I authenticate users?" finds both "User +authentication requires a valid API token" and "Token-based auth validates +requests" despite different wording. It won't find "The authentication tests +are failing" because that's a different meaning despite containing the word. + +This works well for documentation where users ask questions using different +terminology than your docs. The downside is it may miss exact technical terms +and sometimes you want literal matches, not semantic ones. Requires embedding +API calls during indexing. + +### Keyword search (BM25) + +Statistical algorithm that matches and ranks by term frequency and rarity: + +```yaml +strategies: + - type: bm25 + database: ./bm25.db + k1: 1.5 + b: 0.75 + chunking: + size: 1000 + overlap: 100 +``` + +During indexing, documents are tokenized and the algorithm calculates how often +each term appears (term frequency) and how rare it is across all documents +(inverse document frequency). The scoring index is stored in a local SQLite +database. + +When you search for "HandleRequest function", the algorithm finds chunks +containing these exact terms and scores them based on term frequency, term +rarity, and document length. Finding "HandleRequest" is scored as more +significant than finding common words like "function". Think of it as grep with +statistical ranking. + +Example: Searching "HandleRequest function" finds `func HandleRequest(w +http.ResponseWriter, r *http.Request)` and "The HandleRequest function +processes incoming requests", but not "process HTTP requests" despite that +being semantically similar. + +The `k1` parameter (default 1.5) controls how much repeated terms matter - +higher values emphasize repetition more. The `b` parameter (default 0.75) +controls length normalization - higher values penalize longer documents more. + +This is fast, local (no API costs), and predictable for finding function names, +class names, API endpoints, and any identifier that appears verbatim. The +trade-off is zero understanding of meaning - "RetryHandler" and "retry logic" +won't match despite being related. Essential complement to semantic search. + +### LLM-enhanced semantic search (semantic-embeddings) + +Generates semantic summaries with an LLM before embedding, enabling search by +what code does rather than what it's called: + +```yaml +strategies: + - type: semantic-embeddings + embedding_model: openai/text-embedding-3-small + chat_model: openai/gpt-5-mini + vector_dimensions: 1536 + database: ./code.db + ast_context: true + chunking: + size: 1000 + code_aware: true +``` + +During indexing, code is split using AST structure (functions stay intact), +then the `chat_model` generates a semantic summary of each chunk. The summary +gets embedded, not the raw code. When you search, your query matches against +these summaries, but the original code is returned. + +This solves a problem with regular embeddings: raw code embeddings are +dominated by variable names and implementation details. A function called +`processData` that implements retry logic won't semantically match "retry". But +when the LLM summarizes it first, the summary explicitly mentions "retry +logic," making it findable. + +Example: Consider this code: + +```go +func (c *Client) Do(req *Request) (*Response, error) { + for i := 0; i < 3; i++ { + resp, err := c.attempt(req) + if err == nil { return resp, nil } + time.Sleep(time.Duration(1< [!NOTE] +> Currently only Go is supported; support for additional languages is planned. + +For short, focused content like API references: + +```yaml +chunking: + size: 500 + overlap: 50 +``` + +Brief sections need less overlap since they're naturally self-contained. + +Experiment with these values.

Essential +for technical jargon and proper nouns. + +Use LLM-enhanced semantic (semantic-embeddings) for code search by +functionality, finding implementations by behavior rather than name, or complex +technical content requiring deep understanding.

Choose based on whether you +need task results or conversation control. + +#### Sub_agents: Hierarchical task delegation + +Use `sub_agents` for hierarchical task delegation. The parent agent assigns a +specific task to a child agent using the `transfer_task` tool. The child +executes in its own context and returns results. The parent maintains control +and can delegate to multiple agents in sequence. + +This works well for structured workflows where you need to combine results from +specialists, or when tasks have clear boundaries. Each delegated task runs +independently and reports back to the parent. + +**Example:** + +```yaml +agents: + root: + sub_agents: [researcher, analyst] + instruction: | + Delegate research to researcher. + Delegate analysis to analyst. + Combine results and present findings. +``` + +Root calls: `transfer_task(agent="researcher", task="Find pricing data")`. The +researcher completes the task and returns results to root. + +#### Handoffs: Conversation transfer + +Use `handoffs` to transfer conversation control to a different agent. When an +agent uses the `handoff` tool, the new agent takes over completely. The +original agent steps back until someone hands back to it. + +This works well when different agents should own different parts of an ongoing +conversation, or when specialists need to collaborate as peers without a +coordinator managing every step. + +**Example:** + +```yaml +agents: + generalist: + handoffs: [database_expert, security_expert] + instruction: | + Help with general development questions. + If the conversation moves to database optimization, + hand off to database_expert. + If security concerns arise, hand off to security_expert. + + database_expert: + handoffs: [generalist, security_expert] + instruction: Handle database design and optimization. + + security_expert: + handoffs: [generalist, database_expert] + instruction: Review code for security vulnerabilities. +``` + +When the user asks about query performance, generalist executes: +`handoff(agent="database_expert")`. The database expert now owns the +conversation and can continue working with the user directly, or hand off to +security_expert if the discussion shifts to SQL injection concerns. + +### Commands + +Named prompts users invoke with `/command_name`.

Agent processes results and decides next steps + +Agents can call multiple tools in sequence or make decisions based on tool +results. Tool selection is automatic based on the agent's understanding of the +task and available capabilities. + +## Tool types + +cagent supports three types of toolsets: + +Built-in toolsets +: Core functionality built directly into cagent (`filesystem`, `shell`, +`memory`, etc.). These provide essential capabilities for file operations, +command execution, and state management. +MCP toolsets +: Tools provided by Model Context Protocol servers, either local processes +(stdio) or remote servers (HTTP/SSE). MCP enables access to a wide ecosystem +of standardized tools. +Custom toolsets +: Shell scripts wrapped as tools with typed parameters (`script`). This +lets you define domain-specific tools for your use case. + +## Configuration + +Toolsets are configured in your agent's YAML file under the `toolsets` array: + +```yaml +agents: + my_agent: + model: anthropic/claude-sonnet-4-5 + description: A helpful coding assistant + toolsets: + # Built-in toolset + - type: filesystem + + # Built-in toolset with configuration + - type: memory + path: ./memories.db + + # Local MCP server (stdio) + - type: mcp + command: npx + args: ["-y", "@modelcontextprotocol/server-filesystem", "/path/to/dir"] + + # Remote MCP server (SSE) + - type: mcp + remote: + url: https://mcp.example.com/sse + transport_type: sse + headers: + Authorization: Bearer ${API_TOKEN} + + # Custom shell tools + - type: script + tools: + build: + cmd: npm run build + description: Build the project +``` + +### Common configuration options + +All toolset types support these optional properties: + +| Property | Type | Description | +| ------------- | ---------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | +| `instruction` | string | Additional instructions for using the toolset | +| `tools` | array | Specific tool names to enable (defaults to all) | +| `env` | object | Environment variables for the toolset | +| `toon` | string | Comma-delimited regex patterns matching tool names whose JSON outputs should be compressed. Reduces token usage by simplifying/compressing JSON responses from matched tools using automatic encoding. Example: `"search.*,list.*"` | +| `defer` | boolean or array | Control which tools load into initial context. Set to `true` to defer all tools, or array of tool names to defer specific tools. Deferred tools don't consume context until explicitly loaded via `search_tool`/`add_tool`. | + +### Tool selection + +By default, agents have access to all tools from their configured toolsets.

This is useful for large toolsets where most +tools won't be used, significantly reducing context consumption. + +Defer all tools in a toolset: + +```yaml +toolsets: + - type: mcp + command: npx + args: ["-y", "@modelcontextprotocol/server-filesystem", "/path"] + defer: true # All tools load on-demand +``` + +Or defer specific tools while loading others immediately: + +```yaml +toolsets: + - type: mcp + command: npx + args: ["-y", "@modelcontextprotocol/server-filesystem", "/path"] + defer: [search_files, list_directory] # Only these are deferred +``` + +Agents can discover deferred tools via `search_tool` and load them into context +via `add_tool` when needed. Best for toolsets with dozens of tools where only a +few are typically used. + +### Output compression + +The `toon` property compresses JSON outputs from matched tools to reduce token +usage. When a tool's output is JSON, it's automatically compressed using +efficient encoding before being returned to the agent: + +```yaml +toolsets: + - type: mcp + command: npx + args: ["-y", "@modelcontextprotocol/server-github"] + toon: "search.*,list.*" # Compress outputs from search/list tools +``` + +Useful for tools that return large JSON responses (API results, file listings, +search results). The compression is transparent to the agent but can +significantly reduce context consumption for verbose tool outputs. + +### Per-agent tool configuration + +Different agents can have different toolsets: + +```yaml +agents: + coordinator: + model: anthropic/claude-sonnet-4-5 + sub_agents: [code_writer, code_reviewer] + toolsets: + - type: filesystem + tools: [read_file] + + code_writer: + model: openai/gpt-5-mini + toolsets: + - type: filesystem + - type: shell + + code_reviewer: + model: anthropic/claude-sonnet-4-5 + toolsets: + - type: filesystem + tools: [read_file, read_multiple_files] +``` + +This allows specialized agents with focused capabilities, security boundaries, +and optimized performance. + +## Built-in tools reference + +### Filesystem + +The `filesystem` toolset gives your agent the ability to work with +files and directories. Your agent can read files to understand +context, write new files, make targeted edits to existing files, +search for content, and explore directory structures. Essential for +code analysis, documentation updates, configuration management, and +any agent that needs to understand or modify project files. + +Access is restricted to the current working directory by default. Agents can +request access to additional directories at runtime, which requires your +approval. + +#### Configuration + +```yaml +toolsets: + - type: filesystem + + # Optional: restrict to specific tools + - type: filesystem + tools: [read_file, write_file, edit_file] +``` + +### Shell + +The `shell` toolset lets your agent execute commands in your system's shell +environment. Use this for agents that need to run builds, execute tests, manage +processes, interact with CLI tools, or perform system operations. The agent can +run commands in the foreground or background. + +Commands execute in the current working directory and inherit environment +variables from the cagent process. This toolset is powerful but should be used +with appropriate security considerations. + +#### Configuration + +```yaml +toolsets: + - type: shell +``` + +### Think + +The `think` toolset provides your agent with a reasoning scratchpad. The agent +can record thoughts and reasoning steps without taking actions or modifying +data. Particularly useful for complex tasks where the agent needs to plan +multiple steps, verify requirements, or maintain context across a long +conversation. + +Agents use this to break down problems, list applicable rules, verify they have +all needed information, and document their reasoning process before acting. + +#### Configuration + +```yaml +toolsets: + - type: think +``` + +### Todo + +The `todo` toolset gives your agent task-tracking capabilities for managing +multi-step operations. Your agent can break down complex work into discrete +tasks, track progress through each step, and ensure nothing is missed before +completing a request. Especially valuable for agents handling complex +workflows with multiple dependencies. + +The `shared` option allows todos to persist across different agents in a +multi-agent system, enabling coordination. + +#### Configuration + +```yaml +toolsets: + - type: todo + + # Optional: share todos across agents + - type: todo + shared: true +``` + +### Tasks + +The `tasks` toolset is an advanced version of the `todo` toolset, and provides +task management with priorities, dependencies, and persistence. Your agent can +create tasks with different priority levels, establish prerequisite +relationships between tasks, and automatically track which tasks are blocked by +incomplete dependencies. Tasks are sorted by priority and blocking status, +making it easy to identify the next actionable work. + +Tasks are stored in a JSON file and persist across cagent sessions. + +#### Configuration + +```yaml +toolsets: + - type: tasks + + # Optional: specify storage location + - type: tasks + path: ./project-tasks.json +``` + +#### Available tools + +The tasks toolset provides these tools: + +- **create_task**: Create a new task with title, description, priority, and + dependencies +- **get_task**: Retrieve full details of a task by ID, including effective + status +- **update_task**: Modify task fields (title, description, priority, status, + dependencies) +- **delete_task**: Remove a task and clean up its dependencies +- **list_tasks**: List all tasks sorted by priority, optionally filtered by + status or priority +- **next_task**: Get the highest-priority actionable task (not blocked or done) +- **add_dependency**: Add a dependency between tasks (with cycle detection) +- **remove_dependency**: Remove a dependency from a task + +#### Task statuses and priorities + +Tasks have four statuses: `pending`, `in_progress`, `done`, and `blocked`. The +agent automatically calculates the effective status. A task becomes `blocked` +if any of its dependencies are not `done`, regardless of its assigned status. + +Priority levels (from highest to lowest): `critical`, `high`, `medium` +(default), `low`. Tasks are sorted by blocking status first (unblocked tasks +first), then by priority, then by creation time. + +### Memory + +The `memory` toolset allows your agent to store and retrieve information across +conversations and sessions. Your agent can remember user preferences, project +context, previous decisions, and other information that should persist. Useful +for agents that interact with users over time or need to maintain state about +a project or environment. + +Memories are stored in a local database file and persist across cagent +sessions. + +#### Configuration + +```yaml +toolsets: + - type: memory + + # Optional: specify database location + - type: memory + path: ./agent-memories.db +``` + +### Fetch + +The `fetch` toolset enables your agent to retrieve content from HTTP/HTTPS URLs. +Your agent can fetch documentation, API responses, web pages, or any content +accessible via HTTP GET requests. Useful for agents that need to access +external resources, check API documentation, or retrieve web content. + +The agent can specify custom HTTP headers when needed for authentication or +other purposes. + +#### Configuration + +```yaml +toolsets: + - type: fetch +``` + +### User Prompt + +The `user_prompt` toolset lets your agent ask you questions during task +execution. When the agent needs clarification, decisions, or additional +information it can't determine on its own, it displays a dialog and waits for +your response. + +You'll see a prompt with the agent's question. Depending on what the agent +needs, you might provide free-form text, select from options, or fill out a +form with multiple fields. You can accept and provide the information, decline +to answer, or cancel the operation entirely. + +#### Configuration + +```yaml +toolsets: + - type: user_prompt +``` + +No additional configuration is required. The tool becomes available to the +agent once configured. When the agent calls this tool, the user sees a dialog +with the prompt. The user can: + +- **Accept**: Provide the requested information +- **Decline**: Refuse to provide the information +- **Cancel**: Cancel the operation + +### API + +The `api` toolset lets you define custom tools that call HTTP APIs. Similar to +`script` but for web services, this allows you to expose REST APIs, +webhooks, or any HTTP endpoint as a tool your agent can use. The agent sees +these as typed tools with automatic parameter validation. + +Use this to integrate with external services, call internal APIs, trigger +webhooks, or interact with any HTTP-based system. + +#### Configuration + +Each API tool is defined with an `api_config` containing the endpoint, HTTP method, and optional typed parameters: + +```yaml +toolsets: + - type: api + api_config: + name: search_docs + endpoint: https://api.example.com/search + method: GET + instruction: Search the documentation database + headers: + Authorization: Bearer ${API_TOKEN} + args: + query: + type: string + description: Search query + limit: + type: number + description: Maximum results + required: [query] + + - type: api + api_config: + name: create_ticket + endpoint: https://api.example.com/tickets + method: POST + instruction: Create a support ticket + args: + title: + type: string + description: Ticket title + description: + type: string + description: Ticket description + required: [title, description] +``` + +For GET requests, parameters are interpolated into the endpoint URL. For POST +requests, parameters are sent as JSON in the request body. + +Supported argument types: `string`, `number`, `boolean`, `array`, `object`. + +### Script + +The `script` toolset lets you define custom tools by wrapping shell +commands with typed parameters. This allows you to expose domain-specific +operations to your agent as first-class tools. The agent sees these custom +tools just like built-in tools, with parameter validation and type checking +handled automatically. + +Use this to create tools for deployment scripts, build commands, test runners, +or any operation specific to your project or workflow. + +#### Configuration + +Each custom tool is defined with a command, description, and optional typed +parameters: + +```yaml +toolsets: + - type: script + tools: + deploy: + cmd: ./deploy.sh + description: Deploy the application to an environment + args: + environment: + type: string + description: Target environment (dev, staging, prod) + version: + type: string + description: Version to deploy + required: [environment] + + run_tests: + cmd: npm test + description: Run the test suite + args: + filter: + type: string + description: Test name filter pattern +``` + +Supported argument types: `string`, `number`, `boolean`, `array`, `object`. + +#### Tools + +The tools you define become available to your agent. In the previous example, +the agent would have access to `deploy` and `run_tests` tools. + +## Automatic tools + +Some tools are automatically added to agents based on their configuration. You +don't configure these explicitly—they appear when needed. + +### transfer_task + +Automatically available when your agent has `sub_agents` configured. Allows +the agent to delegate tasks to sub-agents and receive results back. + +### handoff + +Automatically available when your agent has `handoffs` configured.

This page answers common questions about MCP Catalog and Toolkit security. + +### What process does Docker follow to add a new MCP server to the catalog? + +Developers can submit a pull request to the [Docker MCP Registry](https://github.com/docker/mcp-registry) to propose new servers. Docker provides detailed [contribution guidelines](https://github.com/docker/mcp-registry/blob/main/CONTRIBUTING.md) to help developers meet the required standards. + +Currently, a majority of the servers in the catalog are built directly by Docker. Each server includes attestations such as: + +- Build attestation: Servers are built on Docker Build Cloud. +- Source provenance: Verifiable source code origins. +- Signed SBOMs: Software Bill of Materials with cryptographic signatures. + +> [!NOTE] +> When using the images with [Docker MCP gateway](/manuals/ai/mcp-catalog-and-toolkit/mcp-gateway.md), +> you can verify attestations at runtime using the `docker mcp gateway run +--verify-signatures` CLI command. + + +In addition to Docker-built servers, the catalog includes select servers from trusted registries such as GitHub and HashiCorp. Each third-party server undergoes a verification process that includes: + +- Pulling and building the code in an ephemeral build environment. +- Testing initialization and functionality. +- Verifying that tools can be successfully listed. + +### Under what conditions does Docker reject MCP server submissions? + +Docker rejects MCP server submissions that fail automated testing and validation processes during pull request review. Additionally, Docker reviewers evaluate submissions against specific requirements and reject MCP servers that don't meet these criteria. + +### Does Docker take accountability for malicious MCP servers in the Toolkit? + +Docker’s security measures currently represent a best-effort approach. While Docker implements automated testing, scanning, and metadata extraction for each server in the catalog, these security measures are not yet exhaustive. Docker is actively working to enhance its security processes and expand testing coverage. Enterprise customers can contact their Docker account manager for specific security requirements and implementation details. + +### How are credentials managed for MCP servers? + +Starting with Docker Desktop version 4.43.0, credentials are stored securely in the Docker Desktop VM. The storage implementation depends on the platform (for example, macOS, WSL2). You can manage the credentials using the following CLI commands: + +- `docker mcp secret ls` - List stored credentials +- `docker mcp secret rm` - Remove specific credentials +- `docker mcp oauth revoke` - Revoke OAuth-based credentials + +In the upcoming versions of Docker Desktop, Docker plans to support pluggable storage for these secrets and additional out-of-the-box storage providers to give users more flexibility in managing credentials. + +### Are credentials removed when an MCP server is uninstalled? + +No. MCP servers are not technically uninstalled since they exist as Docker containers pulled to your local Docker Desktop. Removing an MCP server stops the container but leaves the image on your system. Even if the container is deleted, credentials remain stored until you remove them manually. + +### Why don't I see remote MCP servers in the catalog? + +If remote MCP servers aren't visible in the Docker Desktop catalog, your local +catalog may be out of date. Remote servers are indicated by a cloud icon and +include services like GitHub, Notion, and Linear. + +Update your catalog by running: + +```console +$ docker mcp catalog update +``` + +After the update completes, refresh the **Catalog** tab in Docker Desktop. + +### What's the difference between profiles and the catalog? + +The [catalog](/manuals/ai/mcp-catalog-and-toolkit/catalog.md) is the source of +available MCP servers - a library of tools you can choose from. +[Profiles](/manuals/ai/mcp-catalog-and-toolkit/profiles.md) are collections of +servers you've added to organize your work. Think of the catalog as a library, +and profiles as your personal bookshelves containing the books you've selected +for different purposes. + +### Can I share profiles with my team? + +Yes. Profiles can be pushed to OCI-compliant registries using +`docker mcp profile push my-profile registry.example.com/profiles/my-profile:v1`. +Team members can pull your profile with +`docker mcp profile pull registry.example.com/profiles/my-profile:v1`. Note +that credentials aren't included in shared profiles for security reasons - team +members need to configure OAuth and other credentials separately. + +### Do I need to create a profile to use MCP Toolkit? + +Yes, MCP Toolkit requires a profile to run servers. If you're upgrading from a +version before profiles were introduced, a default profile is automatically +created for you with your existing server configurations. You can create +additional named profiles to organize servers for different projects or +environments. + +### What happens to servers when I switch profiles? + +Each profile contains its own set of servers and configurations. When you run +the gateway with `--profile profile-name`, only servers in that profile are +available to clients. The default profile is used when no profile is specified. +Switching between profiles changes which servers your AI applications can +access. + +### Can I use the same server in multiple profiles? + +Yes. You can add the same MCP server to multiple profiles, each with different +configurations if needed. This is useful when you need the same server with +different settings for different projects or environments. + +## Related pages + +- [Get started with MCP Toolkit](/manuals/ai/mcp-catalog-and-toolkit/get-started.md) +- [Open-source MCP Gateway](/manuals/ai/mcp-catalog-and-toolkit/mcp-gateway.md) diff --git a/content/manuals/ai/mcp-catalog-and-toolkit/get-started.md b/content/manuals/ai/mcp-catalog-and-toolkit/get-started.md new file mode 100644 index 000000000000..4c2f8e8e6913 --- /dev/null +++ b/content/manuals/ai/mcp-catalog-and-toolkit/get-started.md @@ -0,0 +1,388 @@ +--- +title: Get started with Docker MCP Toolkit +linkTitle: Get started +description: Learn how to quickly install and use the MCP Toolkit to set up servers and clients. +keywords: Docker MCP Toolkit, MCP server, MCP client, AI agents +weight: 5 +params: + test_prompt: Use the GitHub MCP server to show me my open pull requests +--- + +{{< summary-bar feature_name="Docker MCP Toolkit" >}} + +> [!NOTE] +> This page describes the MCP Toolkit interface in Docker Desktop 4.62 and +> later.

empowering developers, operators, and security teams." +keywords: MCP Gateway +weight: 40 +aliases: + - /ai/mcp-gateway/ +--- + +The MCP Gateway is Docker's open source solution for orchestrating Model +Context Protocol (MCP) servers. It acts as a centralized proxy between clients +and servers, managing configuration, credentials, and access control. + +When using MCP servers without the MCP Gateway, you need to configure +applications individually for each AI application. With the MCP Gateway, you +configure applications to connect to the Gateway. The Gateway then handles +server lifecycle, routing, and authentication across all servers in your +[profiles](/manuals/ai/mcp-catalog-and-toolkit/profiles.md). + +> [!NOTE] +> If you use Docker Desktop with MCP Toolkit enabled, the Gateway runs +> automatically in the background. You don't need to start or configure it +> manually. This documentation is for users who want to understand how the +> Gateway works or run it directly for advanced use cases. + +> [!TIP] +> E2B sandboxes now include direct access to the Docker MCP Catalog, giving developers +> access to over 200 tools and services to seamlessly build and run AI agents. For +> more information, see [E2B Sandboxes](sandboxes.md). + +## How it works + +MCP Gateway runs MCP servers in isolated Docker containers with restricted +privileges, network access, and resource usage. It includes built-in logging +and call-tracing capabilities to ensure full visibility and governance of AI +tool activity. + +The MCP Gateway manages the server's entire lifecycle. When an AI application +needs to use a tool, it sends a request to the Gateway. The Gateway identifies +which server handles that tool and, if the server isn't already running, starts +it as a Docker container. The Gateway then injects any required credentials, +applies security restrictions, and forwards the request to the server. The +server processes the request and returns the result through the Gateway back to +the AI application. + +The MCP Gateway solves a fundamental problem: MCP servers are just programs +that need to run somewhere. Running them directly on your machine means dealing +with installation, dependencies, updates, and security risks. By running them +as containers managed by the Gateway, you get isolation, consistent +environments, and centralized control. + +The Gateway works with profiles to determine which servers are available. When +you run the Gateway, you specify which profile to use with the `--profile` flag +to determine which servers are made available to clients. + +## Usage + +To use the MCP Gateway, you'll need Docker Desktop with MCP Toolkit enabled. +Follow the [MCP Toolkit guide](toolkit.md) to enable and configure servers +through the Docker Desktop interface, or see +[Use MCP Toolkit from the CLI](cli.md) for terminal-based workflows. + +### Install the MCP Gateway manually + +For Docker Engine without Docker Desktop, you'll need to download and install +the MCP Gateway separately before you can run it. + +1.

Each time +you want to change which servers are available, you'd update Claude Desktop, VS +Code, Cursor, and other tools individually. Profiles solve this by centralizing +your server configurations. + +## What profiles do + +A profile is a named collection of MCP servers with their configurations and +settings. You select servers from the [MCP +Catalog](/manuals/ai/mcp-catalog-and-toolkit/catalog.md) (the source of +available servers) and add them to your profiles (your configured server +collections for specific work). Think of the catalog as a library of tools, and +profiles as your toolboxes organized for different jobs. + +Your "web-dev" profile might include GitHub, Playwright, and database servers. +Your "data-analysis" profile might include spreadsheet, API, and visualization +servers. Connect different AI clients to different profiles, or switch between +profiles as you change tasks. + +When you run the MCP Gateway or connect a client without specifying a profile, +Docker MCP uses your default profile. If you're upgrading from a previous +version of MCP Toolkit, your existing server configurations are already in the +default profile. + +## Profile capabilities + +Each profile maintains its own isolated collection of servers and +configurations. Your "web-dev" profile might include GitHub, Playwright, and +database servers, while your "data-analysis" profile includes spreadsheet, API, +and visualization servers. Create as many profiles as you need, each containing +only the servers relevant to that context. + +You can connect different AI applications to different profiles. When you +connect a client, you specify which profile it should use. This means Claude +Desktop and VS Code can have access to different server collections if needed. + +Profiles can be shared with your team. Push a profile to your registry, and +team members can pull it to get the exact same server collection and +configuration you use. + +## Creating and managing profiles + +### Create a profile + +1. In Docker Desktop, select **MCP Toolkit** and select the **Profiles** tab. +2. Select **Create profile**. +3. Enter a name for your profile (e.g., "web-dev"). +4. Optionally, search and add servers to your profile now, or add them later. +5. Optionally, search and add clients to connect to your profile. +6. Select **Create**. + +Your new profile appears in the profiles list. + +### View profile details + +Select a profile in the **Profiles** tab to view its details. The profile view +has two tabs: + +- **Overview**: Shows the servers in your profile, secrets configuration, and + connected clients. Use the **+** buttons to add more servers or clients. +- **Tools**: Lists all available tools from your profile's servers. You can + enable or disable individual tools. + +### Remove a profile + +1. In the **Profiles** tab, find the profile you want to remove. +2. Select ⋮ next to the profile name, and then **Delete**. +3. Confirm the removal. + +> [!CAUTION] +> Removing a profile deletes all its server configurations and settings, and +> updates the client configuration (removes MCP Toolkit). This action can't be +> undone. + +### Default profile + +When you run the MCP Gateway or use MCP Toolkit without specifying a profile, +Docker MCP uses a profile named `default`, or an empty configuration if a +`default` profile does not exist. + +If you're upgrading from a previous version of MCP Toolkit, your existing +server configurations automatically migrate to the `default` profile. You don't +need to manually recreate your setup - everything continues to work as before. + +You can always specify a different profile using the `--profile` flag with the +gateway command: + +```console +$ docker mcp gateway run --profile web-dev +``` + +## Adding servers to profiles + +Profiles contain the MCP servers you select from the catalog. Add servers to +organize your tools for specific workflows. + +### Add a server + +You can add servers to a profile in two ways. + +From the Catalog tab: + +1. Select the **Catalog** tab. +2. Select the checkbox next to servers you want to add to see which profile to + add them to. +3. Choose your profile from the drop-down. + +From within a profile: + +1. Select the **Profiles** tab and select your profile. +2. In the **Servers** section, select the **+** button. +3. Search for and select servers to add. + +If a server requires OAuth authentication, you're prompted to authorize it. See +[OAuth authentication](/manuals/ai/mcp-catalog-and-toolkit/toolkit.md#oauth-authentication) +for details. + +### List servers in a profile + +Select a profile in the **Profiles** tab to see all servers it contains. + +### Remove a server + +1. Select the **Profiles** tab and select your profile. +2. In the **Servers** section, find the server you want to remove. +3. Select the delete icon next to the server. + +## Configuring profiles + +### Server configuration + +Some servers require configuration beyond authentication. Configure server +settings within your profile. + +1. Select the **Profiles** tab and select your profile. +2. In the **Servers** section, select the configure icon next to the server. +3. Adjust the server's configuration settings as needed. + +### OAuth credentials + +OAuth credentials are shared across all profiles. When you authorize access to +a service like GitHub or Notion, that authorization is available to any server +in any profile that needs it. + +This means all profiles use the same OAuth credentials for a given service. If +you need to use different accounts for different projects, you'll need to +revoke and re-authorize between switching profiles. + +See [OAuth authentication](/manuals/ai/mcp-catalog-and-toolkit/toolkit.md#oauth-authentication) +for details on authorizing servers. + +### Configuration persistence + +Profile configurations persist in your Docker installation. When you restart +Docker Desktop or your system, your profiles, servers, and configurations +remain intact. + +## Sharing profiles + +Profiles can be shared with your team by pushing them to OCI-compliant +registries as artifacts. This is useful for distributing standardized MCP +setups across your organization. Credentials are not included in shared +profiles for security reasons. Team members configure OAuth separately after +pulling. + +### Push a profile + +1. Select the profile you want to share in the **Profiles** tab. +2. Select **Push to Registry**. +3. Enter the registry destination (e.g., `registry.example.com/profiles/web-dev:v1`). +4. Complete authentication if required. + +### Pull a profile + +1. Select **Pull from Registry** in the **Profiles** tab. +2. Enter the registry reference (e.g., `registry.example.com/profiles/team-standard:latest`). +3. Complete authentication if required. + +The profile is downloaded and added to your profiles list. Configure any +required OAuth credentials separately. + +### Team collaboration workflow + +A typical workflow for sharing profiles across a team: + +1. Create and configure a profile with the servers your team needs. +2. Test the profile to ensure it works as expected. +3. Push the profile to your team's registry with a version tag (e.g., + `registry.example.com/profiles/team-dev:v1`). +4. Share the registry reference with your team. +5. Team members pull the profile and configure any required OAuth credentials. + +This ensures everyone uses the same server collection and configuration, +reducing setup time and inconsistencies. + +## Using profiles with clients + +When you connect an AI client to the MCP Gateway, you specify which profile's +servers the client can access. + +### Run the gateway with a profile + +Connect clients to your profile through the **Clients** section in the MCP +Toolkit. You can add clients when creating a profile or add them to existing +profiles later. + +### Configure clients for specific profiles + +When setting up a client manually, you can specify which profile the client +uses. This lets different clients connect to different profiles. + +For example, your Claude Desktop configuration might use: + +```json +{ + "mcpServers": { + "MCP_DOCKER": { + "command": "docker", + "args": ["mcp", "gateway", "run", "--profile", "claude-work"] + } + } +} +``` + +While your VS Code configuration uses a different profile: + +```json +{ + "mcp": { + "servers": { + "MCP_DOCKER": { + "command": "docker", + "args": ["mcp", "gateway", "run", "--profile", "vscode-dev"], + "type": "stdio" + } + } + } +} +``` + +### Switching between profiles + +To switch the profile your clients use, update the client configuration to +specify a different `--profile` value in the gateway command arguments. + +## Further reading + +- [Get started with MCP Toolkit](/manuals/ai/mcp-catalog-and-toolkit/get-started.md) +- [Use MCP Toolkit from the CLI](/manuals/ai/mcp-catalog-and-toolkit/cli.md) +- [MCP Catalog](/manuals/ai/mcp-catalog-and-toolkit/catalog.md) +- [MCP Toolkit](/manuals/ai/mcp-catalog-and-toolkit/toolkit.md) diff --git a/content/manuals/ai/mcp-catalog-and-toolkit/toolkit.md b/content/manuals/ai/mcp-catalog-and-toolkit/toolkit.md new file mode 100644 index 000000000000..7a851c17effe --- /dev/null +++ b/content/manuals/ai/mcp-catalog-and-toolkit/toolkit.md @@ -0,0 +1,199 @@ +--- +title: Docker MCP Toolkit +linkTitle: Toolkit UI +description: Use the MCP Toolkit to set up MCP servers and MCP clients. +keywords: Docker MCP Toolkit, MCP server, MCP client, AI agents +weight: 30 +aliases: + - /desktop/features/gordon/mcp/gordon-mcp-server/ + - /ai/gordon/mcp/gordon-mcp-server/ +--- + +{{< summary-bar feature_name="Docker MCP Toolkit" >}} + +> [!NOTE] +> This page describes the MCP Toolkit interface in Docker Desktop 4.62 and +> later.

Your agent can search the catalog and +> add tools as needed when you connect to the gateway. + +## How the MCP Toolkit works + +MCP introduces two core concepts: MCP clients and MCP servers. + +- MCP clients are typically embedded in LLM-based applications, such as the + Claude Desktop app. They request resources or actions. +- MCP servers are launched by the client to perform the requested tasks, using + any necessary tools, languages, or processes. + +Docker standardizes the development, packaging, and distribution of +applications, including MCP servers. By packaging MCP servers as containers, +Docker eliminates issues related to isolation and environment differences. You +can run a container directly, without managing dependencies or configuring +runtimes. + +Depending on the MCP server, the tools it provides might run within the same +container as the server or in dedicated containers for better isolation. + +The MCP Toolkit organizes servers into profiles: named collections of servers +with their configurations. This lets you maintain different server setups for +different projects or environments. When you connect a client, you specify +which profile it should use. + +## Security + +The Docker MCP Toolkit combines passive and active measures to reduce attack +surfaces and ensure safe runtime behavior. + +### Passive security + +Passive security refers to measures implemented at build-time, when the MCP +server code is packaged into a Docker image. + +- Image signing and attestation: All MCP server images under `mcp/` in the [MCP + Catalog](catalog.md) are built by Docker and digitally signed to verify their + source and integrity. Each image includes a Software Bill of Materials (SBOM) + for full transparency. + +### Active security + +Active security refers to security measures at runtime, before and after tools +are invoked, enforced through resource and access limitations. + +- CPU allocation: MCP tools are run in their own container. They are + restricted to 1 CPU, limiting the impact of potential misuse of computing + resources. + +- Memory allocation: Containers for MCP tools are limited to 2 GB. + +- Filesystem access: By default, MCP Servers have no access to the host filesystem. + The user explicitly selects the servers that will be granted file mounts. + +- Interception of tool requests: Requests to and from tools that contain sensitive + information such as secrets are blocked. + +### OAuth authentication + +Some MCP servers require authentication to access external services like +GitHub, Notion, and Linear. The MCP Toolkit handles OAuth authentication +automatically. You authorize access through your browser, and the Toolkit +manages credentials securely. You don't need to manually create API tokens or +configure authentication for each service. + +#### Authorize a server with OAuth + +1. In Docker Desktop, go to **MCP Toolkit** and select the **Catalog** tab. +2. Find and add an MCP server that requires OAuth. +3. In the server's **Configuration** tab, select the **OAuth** authentication + method. Follow the link to begin the OAuth authorization. +4. Your browser opens the authorization page for the service. Follow the + on-screen instructions to complete authentication. +5. Return to Docker Desktop when authentication is complete. + +View all authorized services in the **OAuth** tab. To revoke access, select +**Revoke** next to the service you want to disconnect. + +## Usage examples + +### Example: Use Claude Desktop as a client + +Imagine you have Claude Desktop installed, and you want to use the GitHub MCP +server and the Puppeteer MCP server. You do not have to install the servers in +Claude Desktop. You can add these 2 MCP servers to your profile in the MCP +Toolkit and connect Claude Desktop as a client: + +1. From the **MCP Toolkit** menu, select the **Catalog** tab and find the **Puppeteer** server and add it to your profile. +1. Repeat for the **GitHub Official** server. +1. From the **Clients** tab, select **Connect** next to **Claude Desktop**. Restart + Claude Desktop if it's running, and it can now access all the servers in the MCP Toolkit. +1. Within Claude Desktop, run a test by submitting the following prompt using the Sonnet 3.5 model: + + ```text + Take a screenshot of docs.docker.com and then invert the colors + ``` + +### Example: Use Visual Studio Code as a client + +You can interact with all your installed MCP servers in Visual Studio Code: + +1.

That's too +much access for autonomous code execution. + +Running the agent in a container doesn't solve this. Containers share the host +kernel (or in the case of Docker Desktop, share the same virtual machine) and +can't safely isolate something that needs its own Docker daemon. +Docker-in-Docker approaches either compromise isolation (privileged mode with +host socket mounting) or create nested daemon complexity. + +MicroVMs provide the isolation boundary needed. Each sandbox gets its own VM +with a private Docker daemon. The agent can build images, start containers, and +run tests without any access to your host Docker environment. When you remove +the sandbox, everything inside - images, containers, packages - is gone. + +## Isolation model + +### Private Docker daemon per sandbox + +Each sandbox runs a complete Docker daemon inside its VM. This daemon is +isolated from your host and from other sandboxes. + +```plaintext +Host system (your Docker Desktop) + ├── Your containers and images + │ + ├── Sandbox VM 1 + │ ├── Docker daemon (isolated) + │ ├── Agent container + │ └── Other containers (created by agent) + │ + └── Sandbox VM 2 + ├── Docker daemon (isolated) + └── Agent container +``` + +When an agent runs `docker build` or `docker compose up`, those commands +execute inside the sandbox using the private daemon. The agent sees only +containers it creates. It cannot access your host containers, images, or +volumes. + +This architecture solves a fundamental constraint: autonomous agents need full +Docker capabilities but cannot safely share your Docker daemon. + +### Hypervisor-level isolation + +Sandboxes use your system's native virtualization: + +- macOS: virtualization.framework +- Windows: Hyper-V {{< badge color=violet text=Experimental >}} + +This provides hypervisor-level isolation between the sandbox and your host. +Unlike containers (which share the host kernel), VMs have separate kernels and +cannot access host resources outside their defined boundaries. + +### What this means for security + +The VM boundary provides: + +- Process isolation - Agent processes run in a separate kernel +- Filesystem isolation - Only your workspace is accessible +- Network isolation - Sandboxes cannot reach each other +- Docker isolation - No access to host daemon, containers, or images + +Network filtering adds an additional control layer for HTTP/HTTPS traffic. See +[Network policies](network-policies.md) for details on that mechanism. + +## Workspace syncing + +### Bidirectional file sync + +Your workspace syncs to the sandbox at the same absolute path: + +- Host: `/Users/alice/projects/myapp` +- Sandbox: `/Users/alice/projects/myapp` + +Changes sync both ways. Edit a file on your host, and the agent sees it. The +agent modifies a file, and you see the change on your host. + +This is file synchronization, not volume mounting. Files are copied between +host and VM. This approach works across different filesystems and maintains +consistent paths regardless of platform differences. + +### Path preservation + +Preserving absolute paths means: + +- File paths in error messages match between host and sandbox +- Hard-coded paths in configuration files work correctly +- Build outputs reference paths you can find on your host + +The agent sees the same directory structure you see, reducing confusion when +debugging issues or reviewing changes. + +## Storage and persistence + +### What persists + +When you create a sandbox, these persist until you remove it: + +- Docker images and containers - Built or pulled by the agent +- Installed packages - System packages added with apt, yum, etc. +- Agent state - Credentials, configuration, history +- Workspace changes - Files created or modified sync back to host + +### What's ephemeral + +Sandboxes are lightweight but not stateless. They persist between runs but are +isolated from each other. Each sandbox maintains its own: + +- Docker daemon state +- Image cache +- Package installations + +When you remove a sandbox with `docker sandbox rm`, the entire VM and its +contents are deleted. Images built inside the sandbox, packages installed, and +any state not synced to your workspace are gone. + +### Disk usage + +Each sandbox consumes disk space for: + +- VM disk image (grows as you build images and install packages) +- Docker images pulled or built inside the sandbox +- Container layers and volumes + +Multiple sandboxes do not share images or layers. Each has its own isolated +Docker daemon and storage. + +## Networking + +### Internet access + +Sandboxes have outbound internet access through your host's network connection. +Agents can install packages, pull images, and access APIs. + +An HTTP/HTTPS filtering proxy runs on your host and is available at +`host.docker.internal:3128`. Agents automatically use this proxy for outbound +web requests. You can configure network policies to control which destinations +are allowed. See [Network policies](network-policies.md). + +### Credential injection + +The HTTP/HTTPS proxy automatically injects credentials into API requests for +supported providers (OpenAI, Anthropic, Google, GitHub, etc.). When you set +environment variables like `OPENAI_API_KEY` or `ANTHROPIC_API_KEY` on your +host, the proxy intercepts outbound requests to those services and adds the +appropriate authentication headers. + +This approach keeps credentials on your host system - they're never stored +inside the sandbox VM. The agent makes API requests without credentials, and +the proxy injects them transparently. When the sandbox is removed, no +credentials remain inside. + +For multi-provider agents (OpenCode, cagent), the proxy automatically selects +the correct credentials based on the API endpoint being called. See individual +[agent configuration](agents/) for credential setup instructions. + +When building custom templates or installing agents manually in the shell +sandbox, some agents may require environment variables like `OPENAI_API_KEY` +to be set before they start. Set these to placeholder values (e.g., +`proxy-managed`) if needed - the proxy will inject actual credentials +regardless of the environment variable value. + +### Sandbox isolation + +Sandboxes cannot communicate with each other. Each VM has its own private +network namespace. An agent in one sandbox cannot reach services or containers +in another sandbox. + +Sandboxes also cannot access your host's `localhost` services. The VM boundary +prevents direct access to services running on your host machine. + +## Lifecycle + +### Creating and running + +`docker sandbox run` initializes a VM with a workspace for a specified agent, +and starts the agent inside an existing sandbox. You can stop and restart the +agent without recreating the VM, preserving installed packages and Docker +images. + +`docker sandbox create` initializes the VM with a workspace but doesn't start +the agent automatically. This separates environment setup from agent execution. + +### State management + +Sandboxes persist until explicitly removed. Stopping an agent doesn't delete +the VM. This means: + +- Installed packages remain available +- Built images stay cached +- Environment setup persists between runs + +Use `docker sandbox rm` to delete a sandbox and reclaim disk space. + +## Comparison to alternatives + +Understanding when to use sandboxes versus other approaches: + +| Approach | Isolation | Agent Docker access | Host impact | Use case | +| --------------------------- | ----------------- | ------------------------ | ----------------------------------- | --------------------------------------------- | +| Sandboxes (microVMs) | Hypervisor-level | Private daemon | None - fully isolated | Autonomous agents building/running containers | +| Container with socket mount | Kernel namespaces | Host daemon (shared) | Agent sees all host containers | Trusted tools that need Docker CLI | +| Docker-in-Docker | Nested containers | Private daemon (complex) | Moderate - privileged mode required | CI/CD environments | +| Host execution | None | Host daemon | Full - direct system access | Manual development by trusted humans | + +Sandboxes trade higher resource overhead (VM + daemon) for complete isolation. +Use containers when you need lightweight packaging without Docker access.

The proxy is +accessible from inside the sandbox at `host.docker.internal:3128`. + +When an agent makes HTTP or HTTPS requests, the proxy: + +1. Checks the policy rules against the host in the request. If the host is + blocked, the request is stopped immediately +2. Connects to the server. If the host was not explicitly allowed, checks the + server's IP address against BlockCIDR rules + +For example, `localhost` is not in the default allow-list, but it's allowed by the +default "allow" policy. Because it's not explicitly allowed, the proxy then checks +the resolved IP addresses (`127.0.0.1` or `::1`) against the BlockCIDR rules. +Since `127.0.0.1/8` and `::1/128` are both blocked by default, this catches any +DNS aliases for localhost like `ip6-localhost`. + +If an agent needs access to a service on localhost, include a port number in +the allow-list (e.g., `localhost:1234`). + +HTTP requests to `host.docker.internal` are rewritten to `localhost`, so only +the name `localhost` will work in the allow-list. + +## Default policy + +New sandboxes use this default policy unless you configure a custom policy: + +**Policy mode:** `allow` (permit all traffic except what's explicitly blocked) + +**Blocked CIDRs:** + +- `10.0.0.0/8` - Private network (Class A) +- `127.0.0.0/8` - Loopback addresses +- `169.254.0.0/16` - Link-local addresses +- `172.16.0.0/12` - Private network (Class B) +- `192.168.0.0/16` - Private network (Class C) +- `::1/128` - IPv6 loopback +- `fc00::/7` - IPv6 unique local addresses +- `fe80::/10` - IPv6 link-local addresses + +**Allowed hosts:** + +- `*.anthropic.com` - Claude API and services +- `platform.claude.com:443` - Claude platform services + +The default policy blocks access to private networks, localhost, and cloud +metadata services while allowing internet access. Explicitly allowed hosts +bypass CIDR checks for performance. + +## Monitor network activity + +View what your agent is accessing and whether requests are being blocked: + +```console +$ docker sandbox network log +``` + +The network log shows aggregated summaries of HTTP/HTTPS network requests: + +- **Allowed requests** - Requests that were permitted by your network policy +- **Blocked requests** - Requests that were denied by your network policy + +For each host accessed, the log shows: + +- **Sandbox** - Name of the sandbox making the request +- **Host** - The destination (hostname and port) +- **Rule** - The policy rule that matched this request (or ``) +- **Last Seen** - When this host was most recently accessed +- **Count** - Number of requests to this host since tracking began + +Use network logs to understand agent behavior, identify blocked requests that +should be allowed, and debug network policy issues. The logs are especially +helpful when defining policies - they show exactly what your agent is trying to +access. + +### Example log output + +```console +$ docker sandbox network log +Blocked requests: +SANDBOX HOST RULE LAST SEEN COUNT +my-sandbox internal.corp.com:443 14:30:15 12-Feb 3 +my-sandbox 192.168.1.100:22 14:25:10 12-Feb 1 + +Allowed requests: +SANDBOX HOST RULE LAST SEEN COUNT +my-sandbox api.anthropic.com:443 api.anthropic.com 14:35:21 12-Feb 15 +my-sandbox registry.npmjs.org:443 *.npmjs.org 14:32:18 12-Feb 8 +my-sandbox raw.githubusercontent.com:443 *.githubusercontent.com 14:30:45 12-Feb 2 +``` + +The log displays both blocked and allowed requests in separate sections. Use +`--json` for machine-readable output, `--quiet` to suppress headers, or +`--limit N` to show only the first N entries. + +## Applying policies + +Use `docker sandbox network proxy` to configure network policies for your +sandboxes. The sandbox must be running when you apply policy changes. Changes +take effect immediately and persist across sandbox restarts. + +### Example: Block internal networks + +Prevent agents from accessing your local network, Docker networks, and cloud +metadata services. It prevents accidental access to internal services while +allowing agents to install packages and access public APIs. + +```console +$ docker sandbox network proxy my-sandbox \ + --policy allow \ + --block-cidr 10.0.0.0/8 \ + --block-cidr 172.16.0.0/12 \ + --block-cidr 192.168.0.0/16 \ + --block-cidr 127.0.0.0/8 +``` + +This policy: + +- Allows internet access +- Blocks RFC 1918 private networks (10.x.x.x, 172.16-31.x.x, 192.168.x.x) +- Blocks localhost (127.x.x.x) + +> [!NOTE] +> These CIDR blocks are already blocked by default. The example above shows how +> to explicitly configure them. See [Default policy](#default-policy) for the +> complete list. + +### Example: Restrict to package managers only + +For strict control, use a denylist policy that only allows package repositories: + +```console +$ docker sandbox network proxy my-sandbox \ + --policy deny \ + --allow-host "*.npmjs.org" \ + --allow-host "*.pypi.org" \ + --allow-host "files.pythonhosted.org" \ + --allow-host "*.rubygems.org" \ + --allow-host github.com +``` + +> [!NOTE] +> This policy would block the backend of your AI coding agent (e.g., for Claude +> Code: `xyz.anthropic.com`). Make sure you also include hostnames that the +> agent requires. + +The agent can install dependencies but can't access arbitrary internet +resources. This is useful for CI/CD environments or when running untrusted code. + +### Example: Allow AI APIs and development tools + +Combine AI service access with package managers and version control: + +```console +$ docker sandbox network proxy my-sandbox \ + --policy deny \ + --allow-host api.anthropic.com \ + --allow-host "*.npmjs.org" \ + --allow-host "*.pypi.org" \ + --allow-host github.com \ + --allow-host "*.githubusercontent.com" +``` + +This allows agents to call AI APIs, install packages, and fetch code from +GitHub while blocking other internet access. + +### Example: Allow specific APIs while blocking subdomains + +Use port-specific rules and subdomain patterns for fine-grained control: + +```console +$ docker sandbox network proxy my-sandbox \ + --policy deny \ + --allow-host api.example.com:443 \ + --allow-host cdn.example.com \ + --allow-host "*.storage.example.com:443" +``` + +This policy allows: + +- Requests to `api.example.com` on port 443 (typically + `https://api.example.com`) +- Requests to `cdn.example.com` on any port +- Requests to any subdomain of `storage.example.com` on port 443, like + `us-west.storage.example.com:443` or `eu-central.storage.example.com:443` + +Requests to `example.com` (any port), `www.example.com` (any port), or +`api.example.com:8080` would all be blocked because none match the specific +patterns. + +To allow both a domain and all its subdomains, specify both patterns: + +```console +$ docker sandbox network proxy my-sandbox \ + --policy deny \ + --allow-host example.com \ + --allow-host "*.example.com" +``` + +## Policy modes: allowlist versus denylist + +Policies have two modes that determine default behavior. + +### Allowlist mode + +Default: Allow all traffic, block specific destinations. + +```console +$ docker sandbox network proxy my-sandbox \ + --policy allow \ + --block-cidr 192.0.2.0/24 \ + --block-host example.com +``` + +Use allowlist mode when you want agents to access most resources but need to +block specific networks or domains. This is less restrictive and works well for +development environments where the agent needs broad internet access. + +### Denylist mode + +Default: Block all traffic, allow specific destinations. + +```console +$ docker sandbox network proxy my-sandbox \ + --policy deny \ + --allow-host api.anthropic.com \ + --allow-host "*.npmjs.org" +``` + +Use denylist mode when you want tight control over external access. This +requires explicitly allowing each service the agent needs, making it more +secure but also more restrictive. Good for production deployments, CI/CD +pipelines, or untrusted code. + +### Domain and CIDR matching + +Domain patterns support exact matches, wildcards, and port specifications: + +- `example.com` matches only that exact domain (any port) +- `example.com:443` matches requests to `example.com` on port 443 (the default + HTTPS port) +- `*.example.com` matches all subdomains like `api.example.com` or + `www.example.com` +- `*.example.com:443` matches requests to any subdomain on port 443 + +Important pattern behaviors: + +- `example.com` does NOT match subdomains. A request to `api.example.com` + won't match a rule for `example.com`. +- `*.example.com` does NOT match the root domain. A request to `example.com` + won't match a rule for `*.example.com`. +- To allow both a domain and its subdomains, specify both patterns: + `example.com` and `*.example.com`. + +When multiple patterns could match a request, the most specific pattern wins: + +1. Exact hostname and port: `api.example.com:443` +2. Exact hostname, any port: `api.example.com` +3. Wildcard patterns (longest match first): `*.api.example.com:443`, + `*.api.example.com`, `*.example.com:443`, `*.example.com` +4. Catch-all wildcards: `*:443`, `*` +5. Default policy (allow or deny) + +This specificity lets you block broad patterns while allowing specific +exceptions. For example, you can block `example.com` and `*.example.com` but +allow `api.example.com:443`. + +CIDR blocks match IP addresses after DNS resolution: + +- `192.0.2.0/24` blocks all 192.0.2.x addresses +- `198.51.100.0/24` blocks all 198.51.100.x addresses +- `203.0.113.0/24` blocks all 203.0.113.x addresses + +When you block or allow a domain, the proxy resolves it to IP addresses and +checks those IPs against CIDR rules. This means blocking a CIDR range affects +any domain that resolves to an IP in that range. + +## Bypass mode for HTTPS tunneling + +By default, the proxy acts as a man-in-the-middle for HTTPS connections, +terminating TLS and re-encrypting traffic with its own certificate authority. +This allows the proxy to enforce policies and inject authentication credentials +for certain services. The sandbox container trusts the proxy's CA certificate. + +Some applications use certificate pinning or other techniques that don't work +with MITM proxies. For these cases, use bypass mode to tunnel HTTPS traffic +directly without inspection: + +```console +$ docker sandbox network proxy my-sandbox \ + --bypass-host api.service-with-pinning.com +``` + +You can also bypass traffic to specific IP ranges: + +```console +$ docker sandbox network proxy my-sandbox \ + --bypass-cidr 203.0.113.0/24 +``` + +When traffic is bypassed, the proxy: + +- Acts as a simple TCP tunnel without inspecting content +- Cannot inject authentication credentials into requests +- Cannot detect domain fronting or other evasion techniques +- Still enforces domain and port matching based on the initial connection + +Use bypass mode only when necessary. Bypassed traffic loses the visibility and +security benefits of MITM inspection. If you bypass broad domains like +`github.com`, the proxy has no visibility into what the agent accesses on that +domain. + +## Policy persistence + +Network policies are stored in JSON configuration files. + +### Per-sandbox configuration + +When you run `docker sandbox network proxy my-sandbox`, the command updates the +configuration for that specific sandbox only. The policy is persisted to +`~/.docker/sandboxes/vm/my-sandbox/proxy-config.json`. + +The default policy (used when creating new sandboxes) remains unchanged unless +you modify it directly. + +### Default configuration + +The default network policy for new sandboxes is stored at +`~/.sandboxd/proxy-config.json`. This file is created automatically when the +first sandbox starts, but only if it doesn't already exist. + +The current default policy is `allow`, which permits all outbound connections +except to blocked CIDR ranges (private networks, localhost, and cloud metadata +services). + +You can modify the default policy: + +1. Edit `~/.sandboxd/proxy-config.json` directly +2. Or copy a sandbox policy to the default location: + + ```console + $ cp ~/.docker/sandboxes/vm/my-sandbox/proxy-config.json ~/.sandboxd/proxy-config.json + ``` + +Review and customize the default policy to match your security requirements +before creating new sandboxes.

Builds run on cloud infrastructure optimally +dimensioned for your workloads, no configuration required. The service uses a +remote build cache, ensuring fast builds anywhere and for all team members. + +## How Docker Build Cloud works + +Using Docker Build Cloud is no different from running a regular build. You invoke a +build the same way you normally would, using `docker buildx build`. The +difference is in where and how that build gets executed. + +By default when you invoke a build command, the build runs on a local instance +of BuildKit, bundled with the Docker daemon. With Docker Build Cloud, you send +the build request to a BuildKit instance running remotely, in the cloud. +All data is encrypted in transit. + +The remote builder executes the build steps, and sends the resulting build +output to the destination that you specify. For example, back to your local +Docker Engine image store, or to an image registry. + +Docker Build Cloud provides several benefits over local builds: + +- Improved build speed +- Shared build cache +- Native multi-platform builds + +And the best part: you don't need to worry about managing builders or +infrastructure. Just connect to your builders, and start building. +Each cloud builder provisioned to an organization is completely +isolated to a single Amazon EC2 instance, with a dedicated EBS volume for build +cache, and encryption in transit. That means there are no shared processes or +data between cloud builders. + +> [!NOTE] +> +> Docker Build Cloud is currently only available in the US East region.

If the same context is used by multiple targets +in a group, that context is transferred once for each time it's used. This can +result in significant impact on build time, depending on your build +configuration. For example, say you have a Bake file that defines the following +group of targets: + +```hcl {title=docker-bake.hcl} +group "default" { + targets = ["target1", "target2"] +} + +target "target1" { + target = "target1" + context = "." +} + +target "target2" { + target = "target2" + context = "." +} +``` + +In this case, the context `.` is transferred twice when you build the default +group: once for `target1` and once for `target2`. + +If your context is small, and if you are using a local builder, duplicate +context transfers may not be a big deal. But if your build context is big, or +you have a large number of targets, or you're transferring the context over a +network to a remote builder, context transfer becomes a performance bottleneck. + +To avoid transferring the same context multiple times, you can define a named +context that only loads the context files, and have each target that needs +those files reference that named context. For example, the following Bake file +defines a named target `ctx`, which is used by both `target1` and `target2`: + +```hcl {title=docker-bake.hcl} +group "default" { + targets = ["target1", "target2"] +} + +target "ctx" { + context = "." + target = "ctx" +} + +target "target1" { + target = "target1" + contexts = { + ctx = "target:ctx" + } +} + +target "target2" { + target = "target2" + contexts = { + ctx = "target:ctx" + } +} +``` + +The named context `ctx` represents a Dockerfile stage, which copies the files +from its context (`.`).

For example: `"nodeselector=kubernetes.io/arch=arm64"` + +The `tolerations` parameter is a semicolon-separated list of taints. It accepts +the same values as the Kubernetes manifest. Each `tolerations` entry specifies +a taint key and the value, operator, or effect. For example: +`"tolerations=key=foo,value=bar;key=foo2,operator=exists;key=foo3,effect=NoSchedule"` + +These options accept CSV-delimited strings as values. Due to quoting rules for +shell commands, you must wrap the values in single quotes. You can even wrap all +of `--driver-opt` in single quotes, for example: + +```console +$ docker buildx create \ + --bootstrap \ + --name=kube \ + --driver=kubernetes \ + '--driver-opt="nodeselector=label1=value1,label2=value2","tolerations=key=key1,value=value1"' +``` + +## Multi-platform builds + +The Kubernetes driver has support for creating +[multi-platform images](/manuals/build/building/multi-platform.md), +either using QEMU or by leveraging the native architecture of nodes. + +### QEMU + +Like the `docker-container` driver, the Kubernetes driver also supports using +[QEMU](https://www.qemu.org/) (user +mode) to build images for non-native platforms. Include the `--platform` flag +and specify which platforms you want to output to. + +For example, to build a Linux image for `amd64` and `arm64`: + +```console +$ docker buildx build \ + --builder=kube \ + --platform=linux/amd64,linux/arm64 \ + -t / \ + --push . +``` + +> [!WARNING] +> +> QEMU performs full-CPU emulation of non-native platforms, which is much +> slower than native builds. Compute-heavy tasks like compilation and +> compression/decompression will likely take a large performance hit. + +Using a custom BuildKit image or invoking non-native binaries in builds may +require that you explicitly turn on QEMU using the `qemu.install` option when +creating the builder: + +```console +$ docker buildx create \ + --bootstrap \ + --name=kube \ + --driver=kubernetes \ + --driver-opt=namespace=buildkit,qemu.install=true +``` + +### Native + +If you have access to cluster nodes of different architectures, the Kubernetes +driver can take advantage of these for native builds. To do this, use the +`--append` flag of `docker buildx create`. + +First, create your builder with explicit support for a single architecture, for +example `amd64`: + +```console +$ docker buildx create \ + --bootstrap \ + --name=kube \ + --driver=kubernetes \ + --platform=linux/amd64 \ + --node=builder-amd64 \ + --driver-opt=namespace=buildkit,nodeselector="kubernetes.io/arch=amd64" +``` + +This creates a Buildx builder named `kube`, containing a single builder node +named `builder-amd64`. Assigning a node name using `--node` is optional.

A smaller base image not only offers +portability and fast downloads, but also shrinks the size of your image and +minimizes the number of vulnerabilities introduced through the dependencies. + +You should also consider using two types of base image: one for building and +unit testing, and another (typically slimmer) image for production. In the +later stages of development, your image may not require build tools such as +compilers, build systems, and debugging tools. A small image with minimal +dependencies can considerably lower the attack surface. + +## Rebuild your images often + +Docker images are immutable.

To keep your images up-to-date and +secure, rebuild your images regularly with updated dependencies. + +### Use --pull to get fresh base images + +The following Dockerfile uses the `24.04` tag of the `ubuntu` image. +Over time, that tag may resolve to a different underlying version of the +`ubuntu` image, as the publisher rebuilds the image with new security +patches and updated libraries. + +```dockerfile +# syntax=docker/dockerfile:1 +FROM ubuntu:24.04 +RUN apt-get -y update && apt-get install -y --no-install-recommends python3 +``` + +To get the latest version of the base image, use the `--pull` flag: + +```console +$ docker build --pull -t my-image:my-tag . +``` + +The `--pull` flag forces Docker to check for and download a newer +version of the base image, even if you have a version cached locally. + +### Use --no-cache for clean builds + +The `--no-cache` flag disables the build cache, forcing Docker to +rebuild all layers from scratch: + +```console +$ docker build --no-cache -t my-image:my-tag . +``` + +This gets the latest available versions of dependencies from package +managers like `apt-get` or `npm`. However, `--no-cache` doesn't pull a +fresh base image - it only prevents reusing cached layers. For a +completely fresh build with the latest base image, combine both flags: + +```console +$ docker build --pull --no-cache -t my-image:my-tag . +``` + +Also consider [pinning base image versions](#pin-base-image-versions). + +## Exclude with .dockerignore + +To exclude files not relevant to the build, without restructuring your source +repository, use a `.dockerignore` file. This file supports exclusion patterns +similar to `.gitignore` files. + +For example, to exclude all files with the `.md` extension: + +```plaintext +*.md +``` + +For information on creating one, see +[Dockerignore file](/manuals/build/concepts/context.md#dockerignore-files). + +## Create ephemeral containers + +The image defined by your Dockerfile should generate containers that are as +ephemeral as possible. Ephemeral means that the container can be stopped +and destroyed, then rebuilt and replaced with an absolute minimum set up and +configuration. + +Refer to [Processes](https://12factor.net/processes) under _The Twelve-factor App_ +methodology to get a feel for the motivations of running containers in such a +stateless fashion. + +## Don't install unnecessary packages + +Avoid installing extra or unnecessary packages just because they might be nice to have. For example, you don’t need to include a text editor in a database image. + +When you avoid installing extra or unnecessary packages, your images have reduced complexity, reduced dependencies, reduced file sizes, and reduced build times. + +## Decouple applications + +Each container should have only one concern. Decoupling applications into +multiple containers makes it easier to scale horizontally and reuse containers. +For instance, a web application stack might consist of three separate +containers, each with its own unique image, to manage the web application, +database, and an in-memory cache in a decoupled manner. + +Limiting each container to one process is a good rule of thumb, but it's not a +hard and fast rule. For example, not only can containers be +[spawned with an init process](/manuals/engine/containers/multi-service_container.md), +some programs might spawn additional processes of their own accord. For +instance, [Celery](https://docs.celeryq.dev/) can spawn multiple worker +processes, and [Apache](https://httpd.apache.org/) can create one process per +request. + +Use your best judgment to keep containers as clean and modular as possible. If +containers depend on each other, you can use [Docker container networks](/manuals/engine/network/_index.md) +to ensure that these containers can communicate. + +## Sort multi-line arguments + +Whenever possible, sort multi-line arguments alphanumerically to make maintenance easier. +This helps to avoid duplication of packages and make the +list much easier to update. This also makes PRs a lot easier to read and +review. Adding a space before a backslash (`\`) helps as well. + +Here’s an example from the [buildpack-deps image](https://github.com/docker-library/buildpack-deps): + +```dockerfile +RUN apt-get update && apt-get install -y --no-install-recommends \ + bzr \ + cvs \ + git \ + mercurial \ + subversion \ + && rm -rf /var/lib/apt/lists/* +``` + +## Leverage build cache + +When building an image, Docker steps through the instructions in your +Dockerfile, executing each in the order specified. For each instruction, Docker +checks whether it can reuse the instruction from the build cache. + +Understanding how the build cache works, and how cache invalidation occurs, +is critical for ensuring faster builds. +For more information about the Docker build cache and how to optimize your builds, +see [Docker build cache](/manuals/build/cache/_index.md). + +## Pin base image versions + +Image tags are mutable, meaning a publisher can update a tag to point to a new +image. This is useful because it lets publishers update tags to point to +newer versions of an image. And as an image consumer, it means you +automatically get the new version when you re-build your image. + +For example, if you specify `FROM alpine:3.21` in your Dockerfile, `3.21` +resolves to the latest patch version for `3.21`. + +```dockerfile +# syntax=docker/dockerfile:1 +FROM alpine:3.21 +``` + +At one point in time, the `3.21` tag might point to version 3.21.1 of the +image. If you rebuild the image 3 months later, the same tag might point to a +different version, such as 3.21.4. This publishing workflow is best practice, +and most publishers use this tagging strategy, but it isn't enforced. + +The downside with this is that you're not guaranteed to get the same for every +build. This could result in breaking changes, and it means you also don't have +an audit trail of the exact image versions that you're using. + +To fully secure your supply chain integrity, you can pin the image version to a +specific digest. By pinning your images to a digest, you're guaranteed to +always use the same image version, even if a publisher replaces the tag with a +new image. For example, the following Dockerfile pins the Alpine image to the +same tag as earlier, `3.21`, but this time with a digest reference as well. + +```dockerfile +# syntax=docker/dockerfile:1 +FROM alpine:3.21@sha256:a8560b36e8b8210634f77d9f7f9efd7ffa463e380b75e2e74aff4511df3ef88c +``` + +With this Dockerfile, even if the publisher updates the `3.21` tag, your builds +would still use the pinned image version: +`a8560b36e8b8210634f77d9f7f9efd7ffa463e380b75e2e74aff4511df3ef88c`. + +While this helps you avoid unexpected changes, it's also more tedious to have +to look up and include the image digest for base image versions manually each +time you want to update it. And you're opting out of automated security fixes, +which is likely something you want to get. + +Docker Scout's default [**Up-to-Date Base Images** +policy](../../scout/policy/_index.md#up-to-date-base-images) checks whether the +base image version you're using is in fact the latest version. This policy also +checks if pinned digests in your Dockerfile correspond to the correct version. +If a publisher updates an image that you've pinned, the policy evaluation +returns a non-compliant status, indicating that you should update your image. + +Docker Scout also supports an automated remediation workflow for keeping your +base images up-to-date. When a new image digest is available, Docker Scout can +automatically raise a pull request on your repository to update your +Dockerfiles to use the latest version. This is better than using a tag that +changes the version automatically, because you're in control and you have an +audit trail of when and how the change occurred. + +For more information about automatically updating your base images with Docker +Scout, see [Remediation](/manuals/scout/policy/remediation.md). + +## Build and test your images in CI + +When you check in a change to source control or create a pull request, use +[GitHub Actions](../ci/github-actions/_index.md) or another CI/CD pipeline to +automatically build and tag a Docker image and test it. + +## Dockerfile instructions + +Follow these recommendations on how to properly use the [Dockerfile instructions](/reference/dockerfile.md) +to create an efficient and maintainable Dockerfile. + +> [!TIP] +> +> To improve linting, code navigation, and vulnerability scanning of your Dockerfiles in Visual Studio Code +> see [Docker VS Code Extension](https://marketplace.visualstudio.com/items?itemName=docker.docker). + +### FROM + +Whenever possible, use current official images as the basis for your +images.

For example: + +```dockerfile +# Set one or more individual labels +LABEL com.example.version="0.0.1-beta" +LABEL vendor1="ACME Incorporated" +LABEL vendor2=ZENITH\ Incorporated +LABEL com.example.release-date="2015-02-12" +LABEL com.example.version.is-production="" +``` + +An image can have more than one label. Prior to Docker 1.10, it was recommended +to combine all labels into a single `LABEL` instruction, to prevent extra layers +from being created. This is no longer necessary, but combining labels is still +supported. For example: + +```dockerfile +# Set multiple labels on one line +LABEL com.example.version="0.0.1-beta" com.example.release-date="2015-02-12" +``` + +The above example can also be written as: + +```dockerfile +# Set multiple labels at once, using line-continuation characters to break long lines +LABEL vendor=ACME\ Incorporated \ + com.example.is-beta= \ + com.example.is-production="" \ + com.example.version="0.0.1-beta" \ + com.example.release-date="2015-02-12" +``` + +See [Understanding object labels](/manuals/engine/manage-resources/labels.md) +for guidelines about acceptable label keys and values. For information about +querying labels, refer to the items related to filtering in +[Managing labels on objects](/manuals/engine/manage-resources/labels.md#manage-labels-on-objects). +See also [LABEL](/reference/dockerfile.md#label) in the Dockerfile reference. + +### RUN + +Split long or complex `RUN` statements on multiple lines separated with +backslashes to make your Dockerfile more readable, understandable, and +maintainable. + +For example, you can chain commands with the `&&` operator, and use +escape characters to break long commands into multiple lines. + +```dockerfile +RUN apt-get update && apt-get install -y --no-install-recommends \ + package-bar \ + package-baz \ + package-foo +``` + +By default, backslash escapes a newline character, but you can change it with +the [`escape` directive](/reference/dockerfile.md#escape). + +You can also use here documents to run multiple commands without chaining them +with a pipeline operator: + +```dockerfile +RUN < /number +``` + +Docker executes these commands using the `/bin/sh -c` interpreter, which only +evaluates the exit code of the last operation in the pipe to determine success. +In the example above, this build step succeeds and produces a new image so long +as the `wc -l` command succeeds, even if the `wget` command fails. + +If you want the command to fail due to an error at any stage in the pipe, +prepend `set -o pipefail &&` to ensure that an unexpected error prevents the +build from inadvertently succeeding. For example: + +```dockerfile +RUN set -o pipefail && wget -O - https://some.site | wc -l > /number +``` + +> [!NOTE] +> +> Not all shells support the `-o pipefail` option. +> +> In cases such as the `dash` shell on +> Debian-based images, consider using the _exec_ form of `RUN` to explicitly +> choose a shell that does support the `pipefail` option. For example: +> +> ```dockerfile +> RUN ["/bin/bash", "-c", "set -o pipefail && wget -O - https://some.site | wc -l > /number"] +> ``` + +### CMD + +The `CMD` instruction should be used to run the software contained in your +image, along with any arguments. `CMD` should almost always be used in the form +of `CMD ["executable", "param1", "param2"]`. Thus, if the image is for a +service, such as Apache and Rails, you would run something like `CMD +["apache2","-DFOREGROUND"]`. Indeed, this form of the instruction is recommended +for any service-based image. + +In most other cases, `CMD` should be given an interactive shell, such as bash, +Python and perl. For example, `CMD ["perl", "-de0"]`, `CMD ["python"]`, or `CMD +["php", "-a"]`. Using this form means that when you execute something like +`docker run -it python`, you’ll get dropped into a usable shell, ready to go. +`CMD` should rarely be used in the manner of `CMD ["param", "param"]` in +conjunction with [`ENTRYPOINT`](/reference/dockerfile.md#entrypoint), unless +you and your expected users are already quite familiar with how `ENTRYPOINT` +works. + +For more information about `CMD`, see [Dockerfile reference for the CMD instruction](/reference/dockerfile.md#cmd). + +### EXPOSE + +The `EXPOSE` instruction indicates the ports on which a container listens +for connections. Consequently, you should use the common, traditional port for +your application. For example, an image containing the Apache web server would +use `EXPOSE 80`, while an image containing MongoDB would use `EXPOSE 27017` and +so on. + +For external access, your users can execute `docker run` with a flag indicating +how to map the specified port to the port of their choice. +For container linking, Docker provides environment variables for the path from +the recipient container back to the source (for example, `MYSQL_PORT_3306_TCP`). + +For more information about `EXPOSE`, see [Dockerfile reference for the EXPOSE instruction](/reference/dockerfile.md#expose). + +### ENV + +To make new software easier to run, you can use `ENV` to update the +`PATH` environment variable for the software your container installs. For +example, `ENV PATH=/usr/local/nginx/bin:$PATH` ensures that `CMD ["nginx"]` +just works. + +The `ENV` instruction is also useful for providing the required environment +variables specific to services you want to containerize, such as Postgres’s +`PGDATA`. + +Lastly, `ENV` can also be used to set commonly used version numbers so that +version bumps are easier to maintain, as seen in the following example: + +```dockerfile +ENV PG_MAJOR=9.3 +ENV PG_VERSION=9.3.4 +RUN curl -SL https://example.com/postgres-$PG_VERSION.tar.xz | tar -xJC /usr/src/postgres && â€Ļ +ENV PATH=/usr/local/postgres-$PG_MAJOR/bin:$PATH +``` + +Similar to having constant variables in a program, as opposed to hard-coding +values, this approach lets you change a single `ENV` instruction to +automatically bump the version of the software in your container. + +Each `ENV` line creates a new intermediate layer, just like `RUN` commands. This +means that even if you unset the environment variable in a future layer, it +still persists in this layer and its value can be dumped. You can test this by +creating a Dockerfile like the following, and then building it. + +```dockerfile +# syntax=docker/dockerfile:1 +FROM alpine +ENV ADMIN_USER="mark" +RUN echo $ADMIN_USER > ./mark +RUN unset ADMIN_USER +``` + +```console +$ docker run --rm test sh -c 'echo $ADMIN_USER' + +mark +``` + +To prevent this and unset the environment variable, use a `RUN` command +with shell commands, to set, use, and unset the variable all in a single layer. +You can separate your commands with `;` or `&&`. If you use the second method, +and one of the commands fails, the `docker build` also fails. This is usually a +good idea. Using `\` as a line continuation character for Linux Dockerfiles +improves readability. You could also put all of the commands into a shell script +and have the `RUN` command just run that shell script. + +```dockerfile +# syntax=docker/dockerfile:1 +FROM alpine +RUN export ADMIN_USER="mark" \ + && echo $ADMIN_USER > ./mark \ + && unset ADMIN_USER +CMD sh +``` + +```console +$ docker run --rm test sh -c 'echo $ADMIN_USER' + +``` + +For more information about `ENV`, see [Dockerfile reference for the ENV instruction](/reference/dockerfile.md#env). + +### ADD or COPY + +`ADD` and `COPY` are functionally similar. `COPY` supports basic copying of +files into the container, from the [build context](/manuals/build/concepts/context.md) +or from a stage in a [multi-stage build](/manuals/build/building/multi-stage.md). +`ADD` supports features for fetching files from remote HTTPS and Git URLs, and +extracting tar files automatically when adding files from the build context. + +You'll mostly want to use `COPY` for copying files from one stage to another in +a multi-stage build. If you need to add files from the build context to the +container temporarily to execute a `RUN` instruction, you can often substitute +the `COPY` instruction with a bind mount instead. For example, to temporarily +add a `requirements.txt` file for a `RUN pip install` instruction: + +```dockerfile +RUN --mount=type=bind,source=requirements.txt,target=/tmp/requirements.txt \ + pip install --requirement /tmp/requirements.txt +``` + +Bind mounts are more efficient than `COPY` for including files from the build +context in the container. Note that bind-mounted files are only added +temporarily for a single `RUN` instruction, and don't persist in the final +image. If you need to include files from the build context in the final image, +use `COPY`. + +The `ADD` instruction is best for when you need to download a remote artifact +as part of your build. `ADD` is better than manually adding files using +something like `wget` and `tar`, because it ensures a more precise build cache. +`ADD` also has built-in support for checksum validation of the remote +resources, and a protocol for parsing branches, tags, and subdirectories from +[Git URLs](/reference/cli/docker/buildx/build/). + +The following example uses `ADD` to download a .NET installer. Combined with +multi-stage builds, only the .NET runtime remains in the final stage, no +intermediate files. + +```dockerfile +# syntax=docker/dockerfile:1 + +FROM scratch AS src +ARG DOTNET_VERSION=8.0.0-preview.6.23329.7 +ADD --checksum=sha256:270d731bd08040c6a3228115de1f74b91cf441c584139ff8f8f6503447cebdbb \ + https://dotnetcli.azureedge.net/dotnet/Runtime/$DOTNET_VERSION/dotnet-runtime-$DOTNET_VERSION-linux-arm64.tar.gz /dotnet.tar.gz + +FROM mcr.microsoft.com/dotnet/runtime-deps:8.0.0-preview.6-bookworm-slim-arm64v8 AS installer + +# Retrieve .NET Runtime +RUN --mount=from=src,target=/src < [!NOTE] +> +> Consider an explicit UID/GID. +> +> Users and groups in an image are assigned a non-deterministic UID/GID in that +> the "next" UID/GID is assigned regardless of image rebuilds.

A workaround is to pass the `--no-log-init` flag to +> `useradd`. The Debian/Ubuntu `adduser` wrapper does not support this flag. + +Avoid installing or using `sudo` as it has unpredictable TTY and +signal-forwarding behavior that can cause problems. If you absolutely need +functionality similar to `sudo`, such as initializing the daemon as `root` but +running it as non-`root`, consider using [“gosu”](https://github.com/tianon/gosu). + +Lastly, to reduce layers and complexity, avoid switching `USER` back and forth +frequently. + +For more information about `USER`, see [Dockerfile reference for the USER instruction](/reference/dockerfile.md#user). + +### WORKDIR + +For clarity and reliability, you should always use absolute paths for your +`WORKDIR`. Also, you should use `WORKDIR` instead of proliferating instructions +like `RUN cd â€Ļ && do-something`, which are hard to read, troubleshoot, and +maintain. + +For more information about `WORKDIR`, see [Dockerfile reference for the `WORKDIR` instruction](/reference/dockerfile.md#workdir). + +### ONBUILD + +An `ONBUILD` command executes after the current Dockerfile build completes. +`ONBUILD` executes in any child image derived `FROM` the current image. Think +of the `ONBUILD` command as an instruction that the parent Dockerfile gives +to the child Dockerfile. + +A Docker build executes `ONBUILD` commands before any command in a child +Dockerfile. + +`ONBUILD` is useful for images that are going to be built `FROM` a given +image. For example, you would use `ONBUILD` for a language stack image that +builds arbitrary user software written in that language within the +Dockerfile, as you can see in [Ruby’s `ONBUILD` variants](https://github.com/docker-library/ruby/blob/c43fef8a60cea31eb9e7d960a076d633cb62ba8d/2.4/jessie/onbuild/Dockerfile). + +Images built with `ONBUILD` should get a separate tag. For example, +`ruby:1.9-onbuild` or `ruby:2.0-onbuild`. + +Be careful when putting `ADD` or `COPY` in `ONBUILD`. The image +fails catastrophically if the new build's context is missing the resource being +added. Adding a separate tag, as recommended above, helps mitigate this by +allowing the Dockerfile author to make a choice. + +For more information about `ONBUILD`, see [Dockerfile reference for the ONBUILD instruction](/reference/dockerfile.md#onbuild). diff --git a/content/manuals/build/building/cdi.md b/content/manuals/build/building/cdi.md new file mode 100644 index 000000000000..ce459f15e1b1 --- /dev/null +++ b/content/manuals/build/building/cdi.md @@ -0,0 +1,540 @@ +--- +title: Container Device Interface (CDI) +weight: 60 +description: Using CDI to access GPUs and other devices in your builds +keywords: build, buildkit, buildx, guide, tutorial, cdi, device, gpu, nvidia, cuda, amd, rocm +--- + + + +The [Container Device Interface (CDI)](https://github.com/cncf-tags/container-device-interface/blob/main/SPEC.md) +is a specification designed to standardize how devices (like GPUs, FPGAs, and +other hardware accelerators) are exposed to and used by containers.

/build/guide/export/ +--- + +Did you know that you can use Docker to build your application to standalone +binaries? Sometimes, you don’t want to package and distribute your application +as a Docker image. Use Docker to build your application, and use exporters to +save the output to disk. + +The default output format for `docker build` is a container image. That image is +automatically loaded to your local image store, where you can run a container +from that image, or push it to a registry. Under the hood, this uses the default +exporter, called the `docker` exporter. + +To export your build results as files instead, you can use the `--output` flag, +or `-o` for short. the `--output` flag lets you change the output format of +your build. + +## Export binaries from a build + +If you specify a filepath to the `docker build --output` flag, Docker exports +the contents of the build container at the end of the build to the specified +location on your host's filesystem. This uses the `local` +[exporter](/manuals/build/exporters/local-tar.md). + +The neat thing about this is that you can use Docker's powerful isolation and +build features to create standalone binaries. This +works well for Go, Rust, and other languages that can compile to a single +binary. + +The following example creates a simple Rust program that prints "Hello, +World!", and exports the binary to the host filesystem. + +1. Create a new directory for this example, and navigate to it: + + ```console + $ mkdir hello-world-bin + $ cd hello-world-bin + ``` + +2. Create a Dockerfile with the following contents: + + ```Dockerfile + # syntax=docker/dockerfile:1 + FROM rust:alpine AS build + WORKDIR /src + COPY < [!TIP] + > The `COPY < It lets you write multi-line strings in a Dockerfile. Here it's used to + > create a simple Rust program inline in the Dockerfile. + + This Dockerfile uses a multi-stage build to compile the program in the first + stage, and then copies the binary to a scratch image in the second. The + final image is a minimal image that only contains the binary. This use case + for the `scratch` image is common for creating minimal build artifacts for + programs that don't require a full operating system to run. + +3. Build the Dockerfile and export the binary to the current working directory: + + ```console + $ docker build --output=. . + ``` + + This command builds the Dockerfile and exports the binary to the current + working directory. The binary is named `hello`, and it's created in the + current working directory. + +## Exporting multi-platform builds + +You use the `local` exporter to export binaries in combination with +[multi-platform builds](/manuals/build/building/multi-platform.md). This lets you +compile multiple binaries at once, that can be run on any machine of any +architecture, provided that the target platform is supported by the compiler +you use. + +Continuing on the example Dockerfile in the +[Export binaries from a build](#export-binaries-from-a-build) section: + +```dockerfile +# syntax=docker/dockerfile:1 +FROM rust:alpine AS build +WORKDIR /src +COPY <}} +{{< tab name="containerd image store" >}} + +The steps for enabling the containerd image store depends on whether you're +using Docker Desktop or Docker Engine standalone: + +- If you're using Docker Desktop, enable the containerd image store in the + [Docker Desktop settings](/manuals/desktop/features/containerd.md). + +- If you're using Docker Engine standalone, enable the containerd image store + using the [daemon configuration file](/manuals/engine/storage/containerd.md). + +{{< /tab >}} +{{< tab name="Custom builder" >}} + +To create a custom builder, use the `docker buildx create` command to create a +builder that uses the `docker-container` driver. + +```console +$ docker buildx create \ + --name container-builder \ + --driver docker-container \ + --bootstrap --use +``` + +> [!NOTE] +> Builds with the `docker-container` driver aren't automatically loaded to your +> Docker Engine image store.

Using emulation, via [QEMU](#qemu) +2. Use a builder with [multiple native nodes](#multiple-native-nodes) +3. Use [cross-compilation](#cross-compilation) with multi-stage builds + +### QEMU + +Building multi-platform images under emulation with QEMU is the easiest way to +get started if your builder already supports it. Using emulation requires no +changes to your Dockerfile, and BuildKit automatically detects the +architectures that are available for emulation. + +> [!NOTE] +> +> Emulation with QEMU can be much slower than native builds, especially for +> compute-heavy tasks like compilation and compression or decompression. +> +> Use [multiple native nodes](#multiple-native-nodes) or +> [cross-compilation](#cross-compilation) instead, if possible. + +Docker Desktop supports running and building multi-platform images under +emulation by default. No configuration is necessary as the builder uses the +QEMU that's bundled within the Docker Desktop VM. + +#### Install QEMU manually + +If you're using a builder outside of Docker Desktop, such as if you're using +Docker Engine on Linux, or a custom remote builder, you need to install QEMU +and register the executable types on the host OS. The prerequisites for +installing QEMU are: + +- Linux kernel version 4.8 or later +- `binfmt-support` version 2.1.7 or later +- The QEMU binaries must be statically compiled and registered with the + `fix_binary` flag + +Use the [`tonistiigi/binfmt`](https://github.com/tonistiigi/binfmt) image to +install QEMU and register the executable types on the host with a single +command: + +```console +$ docker run --privileged --rm tonistiigi/binfmt --install all +``` + +This installs the QEMU binaries and registers them with +[`binfmt_misc`](https://en.wikipedia.org/wiki/Binfmt_misc), enabling QEMU to +execute non-native file formats for emulation. + +Once QEMU is installed and the executable types are registered on the host OS, +they work transparently inside containers. You can verify your registration by +checking if `F` is among the flags in `/proc/sys/fs/binfmt_misc/qemu-*`. + +### Multiple native nodes + +Using multiple native nodes provide better support for more complicated cases +that QEMU can't handle, and also provides better performance. + +You can add additional nodes to a builder using the `--append` flag. + +The following command creates a multi-node builder from Docker contexts named +`node-amd64` and `node-arm64`. This example assumes that you've already added +those contexts. + +```console +$ docker buildx create --use --name mybuild node-amd64 +mybuild +$ docker buildx create --append --name mybuild node-arm64 +$ docker buildx build --platform linux/amd64,linux/arm64 . +``` + +While this approach has advantages over emulation, managing multi-node builders +introduces some overhead of setting up and managing builder clusters. +Alternatively, you can use Docker Build Cloud, a service that provides managed +multi-node builders on Docker's infrastructure. With Docker Build Cloud, you +get native multi-platform ARM and X86 builders without the burden of +maintaining them. Using cloud builders also provides additional benefits, such +as a shared build cache. + +After signing up for Docker Build Cloud, add the builder to your local +environment and start building. + +```console +$ docker buildx create --driver cloud / +cloud-- +$ docker build \ + --builder cloud-- \ + --platform linux/amd64,linux/arm64,linux/arm/v7 \ + --tag \ + --push . +``` + +For more information, see [Docker Build Cloud](/manuals/build-cloud/_index.md). + +### Cross-compilation + +Depending on your project, if the programming language you use has good support +for cross-compilation, you can leverage multi-stage builds to build binaries +for target platforms from the native architecture of the builder. Special build +arguments, such as `BUILDPLATFORM` and `TARGETPLATFORM`, are automatically +available for use in your Dockerfile. + +In the following example, the `FROM` instruction is pinned to the native +platform of the builder (using the `--platform=$BUILDPLATFORM` option) to +prevent emulation from kicking in. Then the pre-defined `$BUILDPLATFORM` and +`$TARGETPLATFORM` build arguments are interpolated in a `RUN` instruction. In +this case, the values are just printed to stdout with `echo`, but this +illustrates how you would pass them to the compiler for cross-compilation. + +```dockerfile +# syntax=docker/dockerfile:1 +FROM --platform=$BUILDPLATFORM golang:alpine AS build +ARG TARGETPLATFORM +ARG BUILDPLATFORM +RUN echo "I am running on $BUILDPLATFORM, building for $TARGETPLATFORM" > /log +FROM alpine +COPY --from=build /log /log +``` + +## Examples + +Here are some examples of multi-platform builds: + +- [Simple multi-platform build using emulation](#simple-multi-platform-build-using-emulation) +- [Multi-platform Neovim build using Docker Build Cloud](#multi-platform-neovim-build-using-docker-build-cloud) +- [Cross-compiling a Go application](#cross-compiling-a-go-application) + +### Simple multi-platform build using emulation + +This example demonstrates how to build a simple multi-platform image using +emulation with QEMU.

Verify that the binaries are built for both platforms.

The application is a simple HTTP server +that listens on port 8080 and returns the architecture of the container. +This example uses Go, but the same principles apply to other programming +languages that support cross-compilation. + +Cross-compilation with Docker builds works by leveraging a series of +pre-defined (in BuildKit) build arguments that give you information about +platforms of the builder and the build targets. You can use these pre-defined +arguments to pass the platform information to the compiler. + +In Go, you can use the `GOOS` and `GOARCH` environment variables to specify the +target platform to build for. + +Prerequisites: + +- Docker Desktop or Docker Engine + +Steps: + +1. Create an empty directory and navigate to it: + + ```console + $ mkdir go-server + $ cd go-server + ``` + +2. Create a base Dockerfile that builds the Go application: + + ```dockerfile + # syntax=docker/dockerfile:1 + FROM golang:alpine AS build + WORKDIR /app + ADD https://github.com/dvdksn/buildme.git#eb6279e0ad8a10003718656c6867539bd9426ad8 . + RUN go build -o server . + + FROM alpine + COPY --from=build /app/server /server + ENTRYPOINT ["/server"] + ``` + + This Dockerfile can't build multi-platform with cross-compilation yet.

These secrets are "pre-flight" secrets: + they are not consumed within your build instruction, but they're used to + provide the builder with the necessary credentials to fetch the context. + +## Using build secrets + +For secret mounts and SSH mounts, using build secrets is a two-step process. +First you need to pass the secret into the `docker build` command, and then you +need to consume the secret in your Dockerfile. + +To pass a secret to a build, use the [`docker build --secret` +flag](/reference/cli/docker/buildx/build/#secret), or the +equivalent options for [Bake](../bake/reference.md#targetsecret). + +{{< tabs >}} +{{< tab name="CLI" >}} + +```console +$ docker build --secret id=aws,src=$HOME/.aws/credentials . +``` + +{{< /tab >}} +{{< tab name="Bake" >}} + +```hcl +variable "HOME" { + default = null +} + +target "default" { + secret = [ + "id=aws,src=${HOME}/.aws/credentials" + ] +} +``` + +{{< /tab >}} +{{< /tabs >}} + +To consume a secret in a build and make it accessible to the `RUN` instruction, +use the [`--mount=type=secret`](/reference/dockerfile.md#run---mounttypesecret) +flag in the Dockerfile. + +```dockerfile +RUN --mount=type=secret,id=aws \ + AWS_SHARED_CREDENTIALS_FILE=/run/secrets/aws \ + aws s3 cp ... +``` + +## Secret mounts + +Secret mounts expose secrets to the build containers, as files or environment +variables. You can use secret mounts to pass sensitive information to your +builds, such as API tokens, passwords, or SSH keys. + +### Sources + +The source of a secret can be either a +[file](/reference/cli/docker/buildx/build/#file) or an +[environment variable](/reference/cli/docker/buildx/build/#typeenv). +When you use the CLI or Bake, the type can be detected automatically. You can +also specify it explicitly with `type=file` or `type=env`. + +The following example mounts the environment variable `KUBECONFIG` to secret ID `kube`, +as a file in the build container at `/run/secrets/kube`. + +```console +$ docker build --secret id=kube,env=KUBECONFIG . +``` + +When you use secrets from environment variables, you can omit the `env` parameter +to bind the secret to a file with the same name as the variable. +In the following example, the value of the `API_TOKEN` variable +is mounted to `/run/secrets/API_TOKEN` in the build container. + +```console +$ docker build --secret id=API_TOKEN . +``` + +### Target + +When consuming a secret in a Dockerfile, the secret is mounted to a file by +default. The default file path of the secret, inside the build container, is +`/run/secrets/`. You can customize how the secrets get mounted in the build +container using the `target` and `env` options for the `RUN --mount` flag in +the Dockerfile. + +The following example takes secret id `aws` and mounts it to a file at +`/run/secrets/aws` in the build container. + +```dockerfile +RUN --mount=type=secret,id=aws \ + AWS_SHARED_CREDENTIALS_FILE=/run/secrets/aws \ + aws s3 cp ... +``` + +To mount a secret as a file with a different name, use the `target` option in +the `--mount` flag. + +```dockerfile +RUN --mount=type=secret,id=aws,target=/root/.aws/credentials \ + aws s3 cp ... +``` + +To mount a secret as an environment variable instead of a file, use the +`env` option in the `--mount` flag. + +```dockerfile +RUN --mount=type=secret,id=aws-key-id,env=AWS_ACCESS_KEY_ID \ + --mount=type=secret,id=aws-secret-key,env=AWS_SECRET_ACCESS_KEY \ + --mount=type=secret,id=aws-session-token,env=AWS_SESSION_TOKEN \ + aws s3 cp ... +``` + +It's possible to use the `target` and `env` options together to mount a secret +as both a file and an environment variable. + +## SSH mounts + +If the credential you want to use in your build is an SSH agent socket or key, +you can use the SSH mount instead of a secret mount. Cloning private Git +repositories is a common use case for SSH mounts. + +The following example clones a private GitHub repository using a [Dockerfile +SSH mount](/reference/dockerfile.md#run---mounttypessh). + +```dockerfile +# syntax=docker/dockerfile:1 +FROM alpine +ADD git@github.com:me/myprivaterepo.git /src/ +``` + +To pass an SSH socket the build, you use the [`docker build --ssh` +flag](/reference/cli/docker/buildx/build/#ssh), or equivalent +options for [Bake](../bake/reference.md#targetssh). + +```console +$ docker buildx build --ssh default . +``` + +## Git authentication for remote contexts + +BuildKit supports two pre-defined build secrets, `GIT_AUTH_TOKEN` and +`GIT_AUTH_HEADER`. Use them to specify HTTP authentication parameters when +building with remote, private Git repositories, including: + +- Building with a private Git repository as build context +- Fetching private Git repositories in a build with `ADD` + +For example, say you have a private GitLab project at +`https://gitlab.com/example/todo-app.git`, and you want to run a build using +that repository as the build context.

arguments and environment variables are similar. +They're both declared in the Dockerfile and can be set using flags for the `docker build` command. +Both can be used to parameterize the build. +But they each serve a distinct purpose. + +### Build arguments + +Build arguments are variables for the Dockerfile itself. +Use them to parameterize values of Dockerfile instructions. +For example, you might use a build argument to specify the version of a dependency to install. + +Build arguments have no effect on the build unless it's used in an instruction. +They're not accessible or present in containers instantiated from the image +unless explicitly passed through from the Dockerfile into the image filesystem or configuration. +They may persist in the image metadata, as provenance attestations and in the image history, +which is why they're not suitable for holding secrets. + +They make Dockerfiles more flexible, and easier to maintain. + +For an example on how you can use build arguments, +see [`ARG` usage example](#arg-usage-example). + +### Environment variables + +Environment variables are passed through to the build execution environment, +and persist in containers instantiated from the image. + +Environment variables are primarily used to: + +- Configure the execution environment for builds +- Set default environment variables for containers + +Environment variables, if set, can directly influence the execution of your build, +and the behavior or configuration of the application. + +You can't override or set an environment variable at build-time. +Values for environment variables must be declared in the Dockerfile. +You can combine environment variables and build arguments to allow +environment variables to be configured at build-time. + +For an example on how to use environment variables for configuring builds, +see [`ENV` usage example](#env-usage-example). + +## `ARG` usage example + +Build arguments are commonly used to specify versions of components, +such as image variants or package versions, used in a build. + +Specifying versions as build arguments lets you build with different versions +without having to manually update the Dockerfile. +It also makes it easier to maintain the Dockerfile, +since it lets you declare versions at the top of the file. + +Build arguments can also be a way to reuse a value in multiple places. +For example, if you use multiple flavors of `alpine` in your build, +you can ensure you're using the same version of `alpine` everywhere: + +- `golang:1.22-alpine${ALPINE_VERSION}` +- `python:3.12-alpine${ALPINE_VERSION}` +- `nginx:1-alpine${ALPINE_VERSION}` + +The following example defines the version of `node` and `alpine` using build arguments. + +```dockerfile +# syntax=docker/dockerfile:1 + +ARG NODE_VERSION="{{% param example_node_version %}}" +ARG ALPINE_VERSION="{{% param example_alpine_version %}}" + +FROM node:${NODE_VERSION}-alpine${ALPINE_VERSION} AS base +WORKDIR /src + +FROM base AS build +COPY package*.json ./ +RUN npm ci +RUN npm run build + +FROM base AS production +COPY package*.json ./ +RUN npm ci --omit=dev && npm cache clean --force +COPY --from=build /src/dist/ . +CMD ["node", "app.js"] +``` + +In this case, the build arguments have default values. +Specifying their values when you invoke a build is optional. +To override the defaults, you would use the `--build-arg` CLI flag: + +```console +$ docker build --build-arg NODE_VERSION=current . +``` + +For more information on how to use build arguments, refer to: + +- [`ARG` Dockerfile reference](/reference/dockerfile.md#arg) +- [`docker build --build-arg` reference](/reference/cli/docker/buildx/build/#build-arg) + +## `ENV` usage example + +Declaring an environment variable with `ENV` makes the variable +available to all subsequent instructions in the build stage. +The following example shows an example setting `NODE_ENV` to `production` +before installing JavaScript dependencies with `npm`. +Setting the variable makes `npm` omits packages needed only for local development. + +```dockerfile +# syntax=docker/dockerfile:1 + +FROM node:20 +WORKDIR /app +COPY package*.json ./ +ENV NODE_ENV=production +RUN npm ci && npm cache clean --force +COPY . . +CMD ["node", "app.js"] +``` + +Environment variables aren't configurable at build-time by default. +If you want to change the value of an `ENV` at build-time, +you can combine environment variables and build arguments: + +```dockerfile +# syntax=docker/dockerfile:1 + +FROM node:20 +ARG NODE_ENV=production +ENV NODE_ENV=$NODE_ENV +WORKDIR /app +COPY package*.json ./ +RUN npm ci && npm cache clean --force +COPY . . +CMD ["node", "app.js"] +``` + +With this Dockerfile, you can use `--build-arg` to override the default value of `NODE_ENV`: + +```console +$ docker build --build-arg NODE_ENV=development . +``` + +Note that, because the environment variables you set persist in containers, +using them can lead to unintended side-effects for the application's runtime. + +For more information on how to use environment variables in builds, refer to: + +- [`ENV` Dockerfile reference](/reference/dockerfile.md#env) + +## Scoping + +Build arguments declared in the global scope of a Dockerfile +aren't automatically inherited into the build stages. +They're only accessible in the global scope. + +```dockerfile +# syntax=docker/dockerfile:1 + +# The following build argument is declared in the global scope: +ARG NAME="joe" + +FROM alpine +# The following instruction doesn't have access to the $NAME build argument +# because the argument was defined in the global scope, not for this stage. +RUN echo "hello ${NAME}!" +``` + +The `echo` command in this example evaluates to `hello !` +because the value of the `NAME` build argument is out of scope. +To inherit global build arguments into a stage, you must consume them: + +```dockerfile +# syntax=docker/dockerfile:1 + +# Declare the build argument in the global scope +ARG NAME="joe" + +FROM alpine +# Consume the build argument in the build stage +ARG NAME +RUN echo $NAME +``` + +Once a build argument is declared or consumed in a stage, +it's automatically inherited by child stages. + +```dockerfile +# syntax=docker/dockerfile:1 +FROM alpine AS base +# Declare the build argument in the build stage +ARG NAME="joe" + +# Create a new stage based on "base" +FROM base AS build +# The NAME build argument is available here +# since it's declared in a parent stage +RUN echo "hello

arguments](/reference/dockerfile.md#automatic-platform-args-in-the-global-scope) + +### Proxy arguments + +Proxy build arguments let you specify proxies to use for your build. +You don't need to declare or reference these arguments in the Dockerfile. +Specifying a proxy with `--build-arg` is enough to make your build use the proxy. + +Proxy arguments are automatically excluded from the build cache +and the output of `docker history` by default. +If you do reference the arguments in your Dockerfile, +the proxy configuration ends up in the build cache. + +The builder respects the following proxy build arguments. +The variables are case insensitive. + +- `HTTP_PROXY` +- `HTTPS_PROXY` +- `FTP_PROXY` +- `NO_PROXY` +- `ALL_PROXY` + +To configure a proxy for your build: + +```console +$

BuildKit is the default builder +for users on Docker Desktop, and Docker Engine as of version 23.0. + +BuildKit provides new functionality and improves your builds' performance. +It also introduces support for handling more complex scenarios: + +- Detect and skip executing unused build stages +- Parallelize building independent build stages +- Incrementally transfer only the changed files in your + [build context](../concepts/context.md) between builds +- Detect and skip transferring unused files in your + [build context](../concepts/context.md) +- Use [Dockerfile frontend](frontend.md) implementations with many + new features +- Avoid side effects with rest of the API (intermediate images and containers) +- Prioritize your build cache for automatic pruning + +Apart from many new features, the main areas BuildKit improves on the current +experience are performance, storage management, and extensibility. From the +performance side, a significant update is a new fully concurrent build graph +solver. It can run build steps in parallel when possible and optimize out +commands that don't have an impact on the final result. +The access to the local source files has also been optimized. By tracking +only the updates made to these +files between repeated build invocations, there is no need to wait for local +files to be read or uploaded before the work can begin. + +## LLB + +At the core of BuildKit is a +[Low-Level Build (LLB)](https://github.com/moby/buildkit#exploring-llb) definition format. LLB is an intermediate binary format +that allows developers to extend BuildKit. LLB defines a content-addressable +dependency graph that can be used to put together complex build +definitions. It also supports features not exposed in Dockerfiles, like direct +data mounting and nested invocation. + +{{< figure src="../images/buildkit-dag.svg" class="invertible" >}} + +Everything about execution and caching of your builds is defined in LLB. The +caching model is entirely rewritten compared to the legacy builder. Rather than +using heuristics to compare images, LLB directly tracks the checksums of build +graphs and content mounted to specific operations. This makes it much faster, +more precise, and portable. The build cache can even be exported to a registry, +where it can be pulled on-demand by subsequent invocations on any host. + +LLB can be generated directly using a +[golang client package](https://pkg.go.dev/github.com/moby/buildkit/client/llb) that allows defining the relationships between your +build operations using Go language primitives. This gives you full power to run +anything you can imagine, but will probably not be how most people will define +their builds. Instead, most users would use a frontend component, or LLB nested +invocation, to run a prepared set of build steps. + +## Frontend + +A frontend is a component that takes a human-readable build format and converts +it to LLB so BuildKit can execute it. Frontends can be distributed as images, +and the user can target a specific version of a frontend that is guaranteed to +work for the features used by their definition. + +For example, to build a [Dockerfile](/reference/dockerfile.md) with +BuildKit, you would +[use an external Dockerfile frontend](frontend.md). + +## Getting started + +BuildKit is the default builder for users on Docker Desktop and Docker Engine +v23.0 and later. + +If you have installed Docker Desktop, you don't need to enable BuildKit. If you +are running a version of Docker Engine version earlier than 23.0, you can enable +BuildKit either by setting an environment variable, or by making BuildKit the +default setting in the daemon configuration. + +To set the BuildKit environment variable when running the `docker build` +command, run: + +```console +$ DOCKER_BUILDKIT=1 docker build . +``` + +> [!NOTE] +> +> Buildx always uses BuildKit. + +To use Docker BuildKit by default, edit the Docker daemon configuration in +`/etc/docker/daemon.json` as follows, and restart the daemon. + +```json +{ + "features": { + "buildkit": true + } +} +``` + +If the `/etc/docker/daemon.json` file doesn't exist, create new file called +`daemon.json` and then add the following to the file.

See the detailed page about each backend type for more +information about which configuration parameters apply. + +The common parameters described here are: + +- [Cache mode](#cache-mode) +- [Cache compression](#cache-compression) +- [OCI media type](#oci-media-types) + +### Cache mode + +When generating a cache output, the `--cache-to` argument accepts a `mode` +option for defining which layers to include in the exported cache. This is +supported by all cache backends except for the `inline` cache. + +Mode can be set to either of two options: `mode=min` or `mode=max`. For example, +to build the cache with `mode=max` with the registry backend: + +```console +$ docker buildx build --push -t / \ + --cache-to type=registry,ref=/,mode=max \ + --cache-from type=registry,ref=/ . +``` + +This option is only set when exporting a cache, using `--cache-to`. When +importing a cache (`--cache-from`) the relevant parameters are automatically +detected. + +In `min` cache mode (the default), only layers that are exported into the +resulting image are cached, while in `max` cache mode, all layers are cached, +even those of intermediate steps. + +While `min` cache is typically smaller (which speeds up import/export times, and +reduces storage costs), `max` cache is more likely to get more cache hits. +Depending on the complexity and location of your build, you should experiment +with both parameters to find the results that work best for you. + +### Cache compression + +The cache compression options are the same as the +[exporter compression options](../../exporters/_index.md#compression). This is +supported by the `local` and `registry` cache backends. + +For example, to compress the `registry` cache with `zstd` compression: + +```console +$ docker buildx build --push -t / \ + --cache-to type=registry,ref=/,compression=zstd \ + --cache-from type=registry,ref=/ . +``` + +### OCI media types + +The cache OCI options are the same as the +[exporter OCI options](../../exporters/_index.md#oci-media-types). These are +supported by the `local` and `registry` cache backends. + +For example, to export OCI media type cache, use the `oci-mediatypes` property: + +```console +$ docker buildx build --push -t / \ + --cache-to type=registry,ref=/,oci-mediatypes=true \ + --cache-from type=registry,ref=/ . +``` + +This property is only meaningful with the `--cache-to` flag. When fetching +cache, BuildKit will auto-detect the correct media types to use. + +By default, the OCI media type generates an image index for the cache image. +Some OCI registries, such as Amazon ECR, don't support the image index media +type: `application/vnd.oci.image.index.v1+json`. If you export cache images to +ECR, or any other registry that doesn't support image indices, set the +`image-manifest` parameter to `true` to generate a single image manifest +instead of an image index for the cache image: + +```console +$ docker buildx build --push -t / \ + --cache-to type=registry,ref=/,oci-mediatypes=true,image-manifest=true \ + --cache-from type=registry,ref=/ . +``` + +> [!NOTE] +> Since BuildKit v0.21, `image-manifest` is enabled by default. diff --git a/content/build/cache/backends/azblob.md b/content/manuals/build/cache/backends/azblob.md similarity index 91% rename from content/build/cache/backends/azblob.md rename to content/manuals/build/cache/backends/azblob.md index 609a0457efe4..7212be5445a5 100644 --- a/content/build/cache/backends/azblob.md +++ b/content/manuals/build/cache/backends/azblob.md @@ -6,18 +6,14 @@ aliases: - /build/building/cache/backends/azblob/ --- -> **Experimental** -> -> This is an experimental feature.

By +default, the `gha` cache backend uses the GitHub Actions cache API to check the +status of cache entries. + +The GitHub Actions cache API is subject to rate limiting if you make too many +requests in a short period of time, which may happen as a result of cache +lookups during a build using the `gha` cache backend. + +```text +#31 exporting to GitHub Actions Cache +#31 preparing build cache for export +#31 preparing build cache for export 600.3s done +#31 ERROR: maximum timeout reached +------ + > exporting to GitHub Actions Cache: +------ +ERROR: failed to solve: maximum timeout reached +make: *** [Makefile:35: release] Error 1 +Error: Process completed with exit code 2. +``` + +To mitigate this issue, you can supply a GitHub token to BuildKit.

If `maxUsedSpace` or `minFreeSpace` would define a lower value, the +minimum cache size would never be brought below `reservedSpace`. + +If both `reservedSpace` and `maxUsedSpace` are set, a GC sweep results in a +cache size between those thresholds. For example, if `reservedSpace` is set to +10GB, and `maxUsedSpace` is set to 20GB, the resulting amount of cache after a +GC run is less than 20GB, but at least 10GB. + +You can also define completely custom GC policies. Custom policies also let you +define filters, which lets you pinpoint the types of cache entries that a given +policy is allowed to prune. + +#### Custom GC policies in BuildKit + +Custom GC policies let you fine-tune how BuildKit manages its cache, and gives +you full control over cache retention based on criteria such as cache type, +duration, or disk space thresholds. If you need full control over the cache +thresholds and how cache records should be prioritized, defining custom GC +policies is the way to go. + +To define a custom GC policy, use the `[[worker.oci.gcpolicy]]` configuration +block in `buildkitd.toml`. Each policy define the thresholds that will be used +for that policy. The global values for `reservedSpace`, `maxUsedSpace`, and +`minFreeSpace` do not apply if you use custom policies. + +Here’s an example configuration: + +```toml +# Custom GC Policy 1: Remove unused local contexts older than 24 hours +[[worker.oci.gcpolicy]] + filters = ["type==source.local"] + keepDuration = "24h" + reservedSpace = "5GB" + maxUsedSpace = "50GB" + +# Custom GC Policy 2: Remove remote Git contexts older than 30 days +[[worker.oci.gcpolicy]] + filters = ["type==source.git.checkout"] + keepDuration = "720h" + reservedSpace = "5GB" + maxUsedSpace = "30GB" + +# Custom GC Policy 3: Aggressively clean all cache if disk usage exceeds 90GB +[[worker.oci.gcpolicy]] + all = true + reservedSpace = "5GB" + maxUsedSpace = "90GB" +``` + +In addition to the `reservedSpace`, `maxUsedSpace`, and `minFreeSpace` threshold, +when defining a GC policy you have two additional configuration options: + +- `all`: By default, BuildKit will exclude some cache records from being pruned + during GC. Setting this option to `true` will allow any cache records to be + pruned. +- `filters`: Filters let you specify specific types of cache records that a GC + policy is allowed to prune. + +See [buildx prune filters](/reference/cli/docker/buildx/prune/#filter) for +information about available GC filters. diff --git a/content/manuals/build/cache/invalidation.md b/content/manuals/build/cache/invalidation.md new file mode 100644 index 000000000000..4bf3ee7d327f --- /dev/null +++ b/content/manuals/build/cache/invalidation.md @@ -0,0 +1,111 @@ +--- +title: Build cache invalidation +description: Dig into the details about how cache invalidation works for Docker's build cache +keywords: build, buildx, buildkit, cache, invalidation, cache miss +--- + +When building an image, Docker steps through the instructions in your +Dockerfile, executing each in the order specified.

The external cache image can be + shared between multiple builds, and across different environments. + +## Order your layers + +Putting the commands in your Dockerfile into a logical order is a great place +to start. Because a change causes a rebuild for steps that follow, try to make +expensive steps appear near the beginning of the Dockerfile. Steps that change +often should appear near the end of the Dockerfile, to avoid triggering +rebuilds of layers that haven't changed. + +Consider the following example. A Dockerfile snippet that runs a JavaScript +build from the source files in the current directory: + +```dockerfile +# syntax=docker/dockerfile:1 +FROM node +WORKDIR /app +COPY . . # Copy over all files in the current directory +RUN npm install # Install dependencies +RUN npm build # Run build +``` + +This Dockerfile is rather inefficient. Updating any file causes a reinstall of +all dependencies every time you build the Docker image even if the dependencies +didn't change since last time. + +Instead, the `COPY` command can be split in two. First, copy over the package +management files (in this case, `package.json` and `yarn.lock`). Then, install +the dependencies. Finally, copy over the project source code, which is subject +to frequent change. + +```dockerfile +# syntax=docker/dockerfile:1 +FROM node +WORKDIR /app +COPY package.json yarn.lock . # Copy package management files +RUN npm install # Install dependencies +COPY . . # Copy over project files +RUN npm build # Run build +``` + +By installing dependencies in earlier layers of the Dockerfile, there is +no need to rebuild those layers when a project file has changed. + +## Keep the context small + +The easiest way to make sure your context doesn't include unnecessary files is +to create a `.dockerignore` file in the root of your build context. The +`.dockerignore` file works similarly to `.gitignore` files, and lets you +exclude files and directories from the build context. + +Here's an example `.dockerignore` file that excludes the `node_modules` +directory, all files and directories that start with `tmp`: + +```plaintext {title=".dockerignore"} +node_modules +tmp* +``` + +Ignore-rules specified in the `.dockerignore` file apply to the entire build +context, including subdirectories. This means it's a rather coarse-grained +mechanism, but it's a good way to exclude files and directories that you know +you don't need in the build context, such as temporary files, log files, and +build artifacts. + +## Use bind mounts + +You might be familiar with bind mounts for when you run containers with `docker +run` or Docker Compose. Bind mounts let you mount a file or directory from the +host machine into a container. + +```bash +# bind mount using the -v flag +docker run -v $(pwd):/path/in/container image-name +# bind mount using the --mount flag +docker run --mount=type=bind,src=.,dst=/path/in/container image-name +``` + +To use bind mounts in a build, you can use the `--mount` flag with the `RUN` +instruction in your Dockerfile: + +```dockerfile +FROM golang:latest +WORKDIR /build +RUN --mount=type=bind,target=. go build -o /app/hello +``` + +In this example, the current directory is mounted into the build container at +`/build` before the `go build` command gets executed. The build output is +written to `/app/hello`, which is outside the mount point. This distinction is +important: the build output must be written outside the bind mount target, +since the mount is read-only by default. The source code is available in the +build container for the duration of that `RUN` instruction. When the +instruction is done executing, the mounted files are not persisted in the final +image, or in the build cache. Only the output of the `go build` command +remains. + +The `COPY` and `ADD` instructions in a Dockerfile lets you copy files from the +build context into the build container. Using bind mounts is beneficial for +build cache optimization because you're not adding unnecessary layers to the +cache. If you have build context that's on the larger side, and it's only used +to generate an artifact, you're better off using bind mounts to temporarily +mount the source code required to generate the artifact into the build. If you +use `COPY` to add the files to the build container, BuildKit will include all +of those files in the cache, even if the files aren't used in the final image. + +There are a few things to be aware of when using bind mounts in a build: + +- Bind mounts are read-only by default. If you need to write to the mounted + directory, you need to specify the `rw` option. However, even with the `rw` + option, the changes are not persisted in the final image or the build cache. + The file writes are sustained for the duration of the `RUN` instruction, and + are discarded after the instruction is done. +- Mounted files are not persisted in the final image. Only the output of the + `RUN` instruction is persisted in the final image. If you need to include + files from the build context in the final image, you need to use the `COPY` + or `ADD` instructions. +- If the target directory is not empty, the contents of the target directory + are hidden by the mounted files. The original contents are restored after the + `RUN` instruction is done. + + {{< accordion title="Example" >}} + + For example, given a build context with only a `Dockerfile` in it: + + ```plaintext + . + └── Dockerfile + ``` + + And a Dockerfile that mounts the current directory into the build container: + + ```dockerfile + FROM alpine:latest + WORKDIR /work + RUN touch foo.txt + RUN --mount=type=bind,target=. ls + RUN ls + ``` + + The first `ls` command with the bind mount shows the contents of the mounted + directory. The second `ls` lists the contents of the original build context. + + ```plaintext {title="Build log"} + #8 [stage-0 3/5] RUN touch foo.txt + #8 DONE 0.1s + + #9 [stage-0 4/5] RUN --mount=target=. ls -1 + #9 0.040 Dockerfile + #9 DONE 0.0s + + #10 [stage-0 5/5] RUN ls -1 + #10 0.046 foo.txt + #10 DONE 0.1s + ``` + + {{< /accordion >}} + +## Use cache mounts + +Regular cache layers in Docker correspond to an exact match of the instruction +and the files it depends on. If the instruction and the files it depends on +have changed since the layer was built, the layer is invalidated, and the build +process has to rebuild the layer. + +Cache mounts are a way to specify a persistent cache location to be used during +builds. The cache is cumulative across builds, so you can read and write to the +cache multiple times. This persistent caching means that even if you need to +rebuild a layer, you only download new or changed packages. Any unchanged +packages are reused from the cache mount. + +To use cache mounts in a build, you can use the `--mount` flag with the `RUN` +instruction in your Dockerfile: + +```dockerfile +FROM node:latest +WORKDIR /app +RUN --mount=type=cache,target=/root/.npm npm install +``` + +In this example, the `npm install` command uses a cache mount for the +`/root/.npm` directory, the default location for the npm cache. The cache mount +is persisted across builds, so even if you end up rebuilding the layer, you +only download new or changed packages. Any changes to the cache are persisted +across builds, and the cache is shared between multiple builds. + +How you specify cache mounts depends on the build tool you're using. If you're +unsure how to specify cache mounts, refer to the documentation for the build +tool you're using. Here are a few examples: + +{{< tabs >}} +{{< tab name="Go" >}} + +```dockerfile +RUN --mount=type=cache,target=/go/pkg/mod \ + --mount=type=cache,target=/root/.cache/go-build \ + go build -o /app/hello +``` + +{{< /tab >}} +{{< tab name="Apt" >}} + +```dockerfile +RUN --mount=type=cache,target=/var/cache/apt,sharing=locked \ + --mount=type=cache,target=/var/lib/apt,sharing=locked \ + apt update && apt-get --no-install-recommends install -y gcc +``` + +{{< /tab >}} +{{< tab name="Python" >}} + +```dockerfile +RUN --mount=type=cache,target=/root/.cache/pip \ + pip install -r requirements.txt +``` + +{{< /tab >}} +{{< tab name="Ruby" >}} + +```dockerfile +RUN --mount=type=cache,target=/root/.gem \ + bundle install +``` + +{{< /tab >}} +{{< tab name="Rust" >}} + +```dockerfile +RUN --mount=type=cache,target=/app/target/ \ + --mount=type=cache,target=/usr/local/cargo/git/db \ + --mount=type=cache,target=/usr/local/cargo/registry/ \ + cargo build +``` + +{{< /tab >}} +{{< tab name=".NET" >}} + +```dockerfile +RUN --mount=type=cache,target=/root/.nuget/packages \ + dotnet restore +``` + +{{< /tab >}} +{{< tab name="PHP" >}} + +```dockerfile +RUN --mount=type=cache,target=/tmp/cache \ + composer install +``` + +{{< /tab >}} +{{< /tabs >}} + +It's important that you read the documentation for the build tool you're using +to make sure you're using the correct cache mount options. Package managers +have different requirements for how they use the cache, and using the wrong +options can lead to unexpected behavior. For example, Apt needs exclusive +access to its data, so the caches use the option `sharing=locked` to ensure +parallel builds using the same cache mount wait for each other and not access +the same cache files at the same time. + +## Use an external cache + +The default cache storage for builds is internal to the builder (BuildKit +instance) you're using. Each builder uses its own cache storage. When you +switch between different builders, the cache is not shared between them. Using +an external cache lets you define a remote location for pushing and pulling +cache data. + +External caches are especially useful for CI/CD pipelines, where the builders +are often ephemeral, and build minutes are precious. Reusing the cache between +builds can drastically speed up the build process and reduce cost. You can even +make use of the same cache in your local development environment. + +To use an external cache, you specify the `--cache-to` and `--cache-from` +options with the `docker buildx build` command. + +- `--cache-to` exports the build cache to the specified location. +- `--cache-from` specifies remote caches for the build to use. + +The following example shows how to set up a GitHub Actions workflow using +`docker/build-push-action`, and push the build cache layers to an OCI registry +image: + +```yaml {title=".github/workflows/ci.yml"} +name: ci + +on: + push: + +jobs: + docker: + runs-on: ubuntu-latest + steps: + - name: Login to Docker Hub + uses: docker/login-action@{{% param "login_action_version" %}} + with: + username: ${{ vars.DOCKERHUB_USERNAME }} + password: ${{ secrets.DOCKERHUB_TOKEN }} + + - name: Set up Docker Buildx + uses: docker/setup-buildx-action@{{% param "setup_buildx_action_version" %}} + + - name: Build and push + uses: docker/build-push-action@{{% param "build_push_action_version" %}} + with: + push: true + tags: user/app:latest + cache-from: type=registry,ref=user/app:buildcache + cache-to: type=registry,ref=user/app:buildcache,mode=max +``` + +This setup tells BuildKit to look for cache in the `user/app:buildcache` image. +And when the build is done, the new build cache is pushed to the same image, +overwriting the old cache. + +This cache can be used locally as well.

Or if you want to build with a +custom Dockerfile, without maintaining your own fork of the repository. + +The following example builds an image using a Dockerfile from stdin, and adds +the `hello.c` file from the [hello-world](https://github.com/docker-library/hello-world) +repository on GitHub. + +```bash +docker build -t myimage:latest -f- https://github.com/docker-library/hello-world.git <}} +{{< tab name="Unix pipe" >}} + +```console +$ docker build - < Dockerfile +``` + +{{< /tab >}} +{{< tab name="PowerShell" >}} + +```powershell +Get-Content Dockerfile | docker build - +``` + +{{< /tab >}} +{{< tab name="Heredocs" >}} + +```bash +docker build -t myimage:latest - <}} +{{< tab name="Remote file" >}} + +```console +$ docker build https://raw.githubusercontent.com/dvdksn/clockbox/main/Dockerfile +``` + +{{< /tab >}} +{{< /tabs >}} + +When you build without a filesystem context, Dockerfile instructions such as +`COPY` can't refer to local files: + +```console +$ ls +main.c +$ docker build -<<< $'FROM scratch\nCOPY main.c .' +[+] Building 0.0s (4/4) FINISHED + => [internal] load build definition from Dockerfile 0.0s + => => transferring dockerfile: 64B 0.0s + => [internal] load .dockerignore 0.0s + => => transferring context: 2B 0.0s + => [internal] load build context 0.0s + => => transferring context: 2B 0.0s + => ERROR [1/1] COPY main.c . 0.0s +------ + > [1/1] COPY main.c .: +------ +Dockerfile:2 +-------------------- + 1 | FROM scratch + 2 | >>> COPY main.c . + 3 | +-------------------- +ERROR: failed to solve: failed to compute cache key: failed to calculate checksum of ref 7ab2bb61-0c28-432e-abf5-a4c3440bc6b6::4lgfpdf54n5uqxnv9v6ymg7ih: "/main.c": not found +``` + +## .dockerignore files + +You can use a `.dockerignore` file to exclude files or directories from the +build context. + +```text +# .dockerignore +node_modules +bar +``` + +This helps avoid sending unwanted files and directories to the builder, +improving build speed, especially when using a remote builder. + +### Filename and location + +When you run a build command, the build client looks for a file named +`.dockerignore` in the root directory of the context. If this file exists, the +files and directories that match patterns in the files are removed from the +build context before it's sent to the builder. + +If you use multiple Dockerfiles, you can use different ignore-files for each +Dockerfile. You do so using a special naming convention for the ignore-files. +Place your ignore-file in the same directory as the Dockerfile, and prefix the +ignore-file with the name of the Dockerfile, as shown in the following example. + +```text +. +├── index.ts +├── src/ +├── docker +│   ├── build.Dockerfile +│   ├── build.Dockerfile.dockerignore +│   ├── lint.Dockerfile +│   ├── lint.Dockerfile.dockerignore +│   ├── test.Dockerfile +│   └── test.Dockerfile.dockerignore +├── package.json +└── package-lock.json +``` + +A Dockerfile-specific ignore-file takes precedence over the `.dockerignore` +file at the root of the build context if both exist. + +### Syntax + +The `.dockerignore` file is a newline-separated list of patterns similar to the +file globs of Unix shells. Leading and trailing slashes in ignore patterns are +disregarded. The following patterns all exclude a file or directory named `bar` +in the subdirectory `foo` under the root of the build context: + +- `/foo/bar/` +- `/foo/bar` +- `foo/bar/` +- `foo/bar` + +If a line in `.dockerignore` file starts with `#` in column 1, then this line +is considered as a comment and is ignored before interpreted by the CLI. + +```gitignore +#/this/is/a/comment +``` + +If you're interested in learning the precise details of the `.dockerignore` +pattern matching logic, check out the +[moby/patternmatcher repository](https://github.com/moby/patternmatcher/tree/main/ignorefile) +on GitHub, which contains the source code. + +#### Matching + +The following code snippet shows an example `.dockerignore` file. + +```text +# comment +*/temp* +*/*/temp* +temp? +``` + + +This file causes the following build behavior: + +| Rule | Behavior | +| :---------- | :------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | +| `# comment` | Ignored. | +| `*/temp*` | Exclude files and directories whose names start with `temp` in any immediate subdirectory of the root. For example, the plain file `/somedir/temporary.txt` is excluded, as is the directory `/somedir/temp`. | +| `*/*/temp*` | Exclude files and directories starting with `temp` from any subdirectory that is two levels below the root. For example, `/somedir/subdir/temporary.txt` is excluded. | +| `temp?` | Exclude files and directories in the root directory whose names are a one-character extension of `temp`. For example, `/tempa` and `/tempb` are excluded. | + + + +Matching is done using Go's +[`filepath.Match` function](https://golang.org/pkg/path/filepath#Match) rules. +A preprocessing step uses Go's +[`filepath.Clean` function](https://golang.org/pkg/path/filepath/#Clean) +to trim whitespace and remove `.` and `..`. +Lines that are blank after preprocessing are ignored. + +> [!NOTE] +> +> For historical reasons, the pattern `.` is ignored. + +Beyond Go's `filepath.Match` rules, Docker also supports a special wildcard +string `**` that matches any number of directories (including zero). For +example, `**/*.go` excludes all files that end with `.go` found anywhere in the +build context. + +You can use the `.dockerignore` file to exclude the `Dockerfile` and +`.dockerignore` files. These files are still sent to the builder as they're +needed for running the build. But you can't copy the files into the image using +`ADD`, `COPY`, or bind mounts. + +#### Negating matches + +You can prepend lines with a `!` (exclamation mark) to make exceptions to +exclusions. The following is an example `.dockerignore` file that uses this +mechanism: + +```text +*.md +!README.md +``` + +All markdown files right under the context directory _except_ `README.md` are +excluded from the context. Note that markdown files under subdirectories are +still included. + +The placement of `!` exception rules influences the behavior: the last line of +the `.dockerignore` that matches a particular file determines whether it's +included or excluded. Consider the following example: + +```text +*.md +!README*.md +README-secret.md +``` + +No markdown files are included in the context except README files other than +`README-secret.md`. + +Now consider this example: + +```text +*.md +README-secret.md +!README*.md +``` + +All of the README files are included. The middle line has no effect because +`!README*.md` matches `README-secret.md` and comes last. + +## Named contexts + +In addition to the default build context (the positional argument to the +`docker build` command), you can also pass additional named contexts to builds. + +Named contexts are specified using the `--build-context` flag, followed by a +name-value pair. This lets you include files and directories from multiple +sources during the build, while keeping them logically separated. + +```console +$ docker build --build-context docs=./docs . +``` + +In this example: + +- The named `docs` context points to the `./docs` directory. +- The default context (`.`) points to the current working directory. + +### Using named contexts in a Dockerfile + +Dockerfile instructions can reference named contexts as if they are stages in a +multi-stage build. + +For example, the following Dockerfile: + +1. Uses a `COPY` instruction to copy files from the default context into the + current build stage. +2. Bind mounts the files in a named context to process the files as part of the + build. + +```dockerfile +# syntax=docker/dockerfile:1 +FROM buildbase +WORKDIR /app + +# Copy all files from the default context into /app/src in the build container +COPY . /app/src +RUN make bin + +# Mount the files from the named "docs" context to build the documentation +RUN --mount=from=docs,target=/app/docs \ + make manpages +``` + +### Use cases for named contexts + +Using named contexts allows for greater flexibility and efficiency when +building Docker images. Here are some scenarios where using named contexts can +be useful: + +#### Example: combine local and remote sources + +You can define separate named contexts for different types of sources. For +example, consider a project where the application source code is local, but the +deployment scripts are stored in a Git repository: + +```console +$ docker build --build-context scripts=https://github.com/user/deployment-scripts.git . +``` + +In the Dockerfile, you can use these contexts independently: + +```dockerfile +# syntax=docker/dockerfile:1 +FROM alpine:latest + +# Copy application code from the main context +COPY . /opt/app + +# Run deployment scripts using the remote "scripts" context +RUN --mount=from=scripts,target=/scripts /scripts/main.sh +``` + +#### Example: dynamic builds with custom dependencies + +In some scenarios, you might need to dynamically inject configuration files or +dependencies into the build from external sources. Named contexts make this +straightforward by allowing you to mount different configurations without +modifying the default build context. + +```console +$ docker build --build-context config=./configs/prod . +``` + +Example Dockerfile: + +```dockerfile +# syntax=docker/dockerfile:1 +FROM nginx:alpine + +# Use the "config" context for environment-specific configurations +COPY --from=config nginx.conf /etc/nginx/nginx.conf +``` + +#### Example: pin or override images + +You can refer to named contexts in a Dockerfile the same way you can refer to +an image. That means you can change an image reference in your Dockerfile by +overriding it with a named context. For example, given the following +Dockerfile: + +```dockerfile +FROM alpine:{{% param example_alpine_version %}} +``` + +If you want to force image reference to resolve to a different version, without +changing the Dockerfile, you can pass a context with the same name to the +build. For example: + +```console +docker buildx build --build-context alpine:{{% param example_alpine_version %}}=docker-image://alpine:edge . +``` + +The `docker-image://` prefix marks the context as an image reference. The +reference can be a local image or an image in your registry. + +### Named contexts with Bake + +[Bake](/manuals/build/bake/_index.md) is a tool built into `docker build` that +lets you manage your build configuration with a configuration file. Bake fully +supports named contexts. + +To define named contexts in a Bake file: + +```hcl {title=docker-bake.hcl} +target "app" { + contexts = { + docs = "./docs" + } +} +``` + +This is equivalent to the following CLI invocation: + +```console +$ docker build --build-context docs=./docs . +``` + +#### Linking targets with named contexts + +In addition to making complex builds more manageable, Bake also provides +additional features on top of what you can do with `docker build` on the CLI. +You can use named contexts to create build pipelines, where one target depends +on and builds on top of another. For example, consider a Docker build setup +where you have two Dockerfiles: + +- `base.Dockerfile`: for building a base image +- `app.Dockerfile`: for building an application image + +The `app.Dockerfile` uses the image produced by `base.Dockerfile` as it's base +image: + +```dockerfile {title=app.Dockerfile} +FROM mybaseimage +``` + +Normally, you would have to build the base image first, and then either load it +to Docker Engine's local image store or push it to a registry. With Bake, you +can reference other targets directly, creating a dependency between the `app` +target and the `base` target. + +```hcl {title=docker-bake.hcl} +target "base" { + dockerfile = "base.Dockerfile" +} + +target "app" { + dockerfile = "app.Dockerfile" + contexts = { + # the target: prefix indicates that 'base' is a Bake target + mybaseimage = "target:base" + } +} +``` + +With this configuration, references to `mybaseimage` in `app.Dockerfile` use +the results from building the `base` target.

Dockerfiles can +start simple and grow with your needs to support more complex scenarios. + +### Filename + +The default filename to use for a Dockerfile is `Dockerfile`, without a file +extension. Using the default name allows you to run the `docker build` command +without having to specify additional command flags. + +Some projects may need distinct Dockerfiles for specific purposes. A common +convention is to name these `.Dockerfile`. You can specify the +Dockerfile filename using the `--file` flag for the `docker build` command. +Refer to the +[`docker build` CLI reference](/reference/cli/docker/buildx/build/#file) +to learn about the `--file` flag. + +> [!NOTE] +> +> We recommend using the default (`Dockerfile`) for your project's primary +> Dockerfile. + +## Docker images + +Docker images consist of layers. Each layer is the result of a build +instruction in the Dockerfile. Layers are stacked sequentially, and each one is +a delta representing the changes applied to the previous layer. + +### Example + +Here's what a typical workflow for building applications with Docker looks like. + +The following example code shows a small "Hello World" application written in +Python, using the Flask framework. + +```python +from flask import Flask +app = Flask(__name__) + +@app.route("/") +def hello(): + return "Hello World!" +``` + +In order to ship and deploy this application without Docker Build, you would +need to make sure that: + +- The required runtime dependencies are installed on the server +- The Python code gets uploaded to the server's filesystem +- The server starts your application, using the necessary parameters + +The following Dockerfile creates a container image, which has all the +dependencies installed and that automatically starts your application. + +```dockerfile +# syntax=docker/dockerfile:1 +FROM ubuntu:22.04 + +# install app dependencies +RUN apt-get update && apt-get install -y python3 python3-pip +RUN pip install flask==3.0.* + +# install app +COPY hello.py / + +# final configuration +ENV FLASK_APP=hello +EXPOSE 8000 +CMD ["flask", "run", "--host", "0.0.0.0", "--port", "8000"] +``` + +Here's a breakdown of what this Dockerfile does: + +- [Dockerfile syntax](#dockerfile-syntax) +- [Base image](#base-image) +- [Environment setup](#environment-setup) +- [Comments](#comments) +- [Installing dependencies](#installing-dependencies) +- [Copying files](#copying-files) +- [Setting environment variables](#setting-environment-variables) +- [Exposed ports](#exposed-ports) +- [Starting the application](#starting-the-application) + +### Dockerfile syntax + +The first line to add to a Dockerfile is a [`# syntax` parser directive](/reference/dockerfile.md#syntax). +While optional, this directive instructs the Docker builder what syntax to use +when parsing the Dockerfile, and allows older Docker versions with [BuildKit enabled](../buildkit/_index.md#getting-started) +to use a specific [Dockerfile frontend](../buildkit/frontend.md) before +starting the build. [Parser directives](/reference/dockerfile.md#parser-directives) +must appear before any other comment, whitespace, or Dockerfile instruction in +your Dockerfile, and should be the first line in Dockerfiles. + +```dockerfile +# syntax=docker/dockerfile:1 +``` + +> [!TIP] +> +> We recommend using `docker/dockerfile:1`, which always points to the latest +> release of the version 1 syntax. BuildKit automatically checks for updates of +> the syntax before building, making sure you are using the most current version. + +### Base image + +The line following the syntax directive defines what base image to use: + +```dockerfile +FROM ubuntu:22.04 +``` + +The [`FROM` instruction](/reference/dockerfile.md#from) sets your base +image to the 22.04 release of Ubuntu. All instructions that follow are executed +in this base image: an Ubuntu environment. The notation `ubuntu:22.04`, follows +the `name:tag` standard for naming Docker images. When you build images, you +use this notation to name your images. There are many public images you can +leverage in your projects, by importing them into your build steps using the +Dockerfile `FROM` instruction. + +[Docker Hub](https://hub.docker.com/search?badges=official) +contains a large set of official images that you can use for this purpose. + +### Environment setup + +The following line executes a build command inside the base image. + +```dockerfile +# install app dependencies +RUN apt-get update && apt-get install -y python3 python3-pip +``` + +This [`RUN` instruction](/reference/dockerfile.md#run) executes a +shell in Ubuntu that updates the APT package index and installs Python tools in +the container. + +### Comments + +Note the `# install app dependencies` line. This is a comment. Comments in +Dockerfiles begin with the `#` symbol. As your Dockerfile evolves, comments can +be instrumental to document how your Dockerfile works for any future readers +and editors of the file, including your future self. + +> [!NOTE] +> +> You might've noticed that comments are denoted using the same symbol as the +> [syntax directive](#dockerfile-syntax) on the first line of the file. +> The symbol is only interpreted as a directive if the pattern matches a +> directive and appears at the beginning of the Dockerfile. Otherwise, it's +> treated as a comment. + +### Installing dependencies + +The second `RUN` instruction installs the `flask` dependency required by the +Python application. + +```dockerfile +RUN pip install flask==3.0.* +``` + +A prerequisite for this instruction is that `pip` is installed into the build +container. The first `RUN` command installs `pip`, which ensures that we can +use the command to install the flask web framework. + +### Copying files + +The next instruction uses the +[`COPY` instruction](/reference/dockerfile.md#copy) to copy the +`hello.py` file from the local build context into the root directory of our image. + +```dockerfile +COPY hello.py / +``` + +A [build context](./context.md) is the set of files that you can access +in Dockerfile instructions such as `COPY` and `ADD`. + +After the `COPY` instruction, the `hello.py` file is added to the filesystem +of the build container. + +### Setting environment variables + +If your application uses environment variables, you can set environment variables +in your Docker build using the [`ENV` instruction](/reference/dockerfile.md#env). + +```dockerfile +ENV FLASK_APP=hello +``` + +This sets a Linux environment variable we'll need later. Flask, the framework +used in this example, uses this variable to start the application. Without this, +flask wouldn't know where to find our application to be able to run it. + +### Exposed ports + +The [`EXPOSE` instruction](/reference/dockerfile.md#expose) marks that +our final image has a service listening on port `8000`. + +```dockerfile +EXPOSE 8000 +``` + +This instruction isn't required, but it is a good practice and helps tools and +team members understand what this application is doing. + +### Starting the application + +Finally, [`CMD` instruction](/reference/dockerfile.md#cmd) sets the +command that is run when the user starts a container based on this image. + +```dockerfile +CMD ["flask", "run", "--host", "0.0.0.0", "--port", "8000"] +``` + +This command starts the flask development server listening on all addresses +on port `8000`. The example here uses the "exec form" version of `CMD`. +It's also possible to use the "shell form": + +```dockerfile +CMD flask run --host 0.0.0.0 --port 8000 +``` + +There are subtle differences between these two versions, +for example in how they trap signals like `SIGTERM` and `SIGKILL`. +For more information about these differences, see +[Shell and exec form](/reference/dockerfile.md#shell-and-exec-form) + +## Building + +To build a container image using the Dockerfile example from the +[previous section](#example), you use the `docker build` command: + +```console +$ docker build -t test:latest . +``` + +The `-t test:latest` option specifies the name and tag of the image. + +The single dot (`.`) at the end of the command sets the +[build context](./context.md) to the current directory. This means that the +build expects to find the Dockerfile and the `hello.py` file in the directory +where the command is invoked. If those files aren't there, the build fails. + +After the image has been built, you can run the application as a container with +`docker run`, specifying the image name: + +```console +$ docker run -p 127.0.0.1:8000:8000 test:latest +``` + +This publishes the container's port 8000 to `http://localhost:8000` on the +Docker host. + +> [!TIP] +> +> To improve linting, code navigation, and vulnerability scanning of your Dockerfiles in Visual Studio Code +> see [Docker VS Code Extension](https://marketplace.visualstudio.com/items?itemName=docker.docker). diff --git a/content/manuals/build/concepts/overview.md b/content/manuals/build/concepts/overview.md new file mode 100644 index 000000000000..e8a101e649f2 --- /dev/null +++ b/content/manuals/build/concepts/overview.md @@ -0,0 +1,78 @@ +--- +title: Docker Build Overview +weight: 10 +description: Learn about Docker Build and its components. +keywords: build, buildkit, buildx, architecture +aliases: +- /build/install-buildx/ +- /build/architecture/ +--- + +Docker Build implements a client-server architecture, where: + +- Client: Buildx is the client and the user interface for running and managing builds. +- Server: BuildKit is the server, or builder, that handles the build execution. + +When you invoke a build, the Buildx client sends a build request to the +BuildKit backend.

The following sections +describe some common scenarios, and how you can use exporters to generate the +output that you need. + +### Load to image store + +Buildx is often used to build container images that can be loaded to an image +store. That's where the `docker` exporter comes in. The following example shows +how to build an image using the `docker` exporter, and have that image loaded to +the local image store, using the `--output` option: + +```console +$ docker buildx build \ + --output type=docker,name=/ . +``` + +Buildx CLI will automatically use the `docker` exporter and load it to the image +store if you supply the `--tag` and `--load` options: + +```console +$ docker buildx build --tag / --load . +``` + +Building images using the `docker` driver are automatically loaded to the local +image store. + +Images loaded to the image store are available to `docker run` immediately +after the build finishes, and you'll see them in the list of images when you run +the `docker images` command. + +### Push to registry + +To push a built image to a container registry, you can use the `registry` or +`image` exporters. + +When you pass the `--push` option to the Buildx CLI, you instruct BuildKit to +push the built image to the specified registry: + +```console +$ docker buildx build --tag / --push . +``` + +Under the hood, this uses the `image` exporter, and sets the `push` parameter. +It's the same as using the following long-form command using the `--output` +option: + +```console +$ docker buildx build \ + --output type=image,name=/,push=true . +``` + +You can also use the `registry` exporter, which does the same thing: + +```console +$ docker buildx build \ + --output type=registry,name=/ . +``` + +### Export image layout to file + +You can use either the `oci` or `docker` exporters to save the build results to +image layout on your local filesystem. Both of these exporters generate a tar +archive file containing the corresponding image layout.

The `tar` exporter creates a tarball archive file. + +```console +$ docker buildx build --output type=local,dest= . +``` + +The `local` exporter is useful in [multi-stage builds](../building/multi-stage.md) +since it allows you to export only a minimal number of build artifacts, such as +self-contained binaries. + +### Cache-only export + +The `cacheonly` exporter can be used if you just want to run a build, without +exporting any output. This can be useful if, for example, you want to run a test +build. Or, if you want to run the build first, and create exports using +subsequent commands. The `cacheonly` exporter creates a build cache, so any +successive builds are instant. + +```console +$ docker buildx build --output type=cacheonly +``` + +If you don't specify an exporter, and you don't provide short-hand options like +`--load` that automatically selects the appropriate exporter, Buildx defaults to +using the `cacheonly` exporter. Except if you build using the `docker` driver, +in which case you use the `docker` exporter. + +Buildx logs a warning message when using `cacheonly` as a default: + +```console +$ docker buildx build . +WARNING: No output specified with docker-container driver. + Build result will only remain in the build cache. + To push result image into registry use --push or + to load image into docker use --load +``` + +## Multiple exporters + +{{< summary-bar feature_name="Build multiple exporters" >}} + +You can use multiple exporters for any given build by specifying the `--output` +flag multiple times.

Developers share and reuse code because it helps increase productivity, +allowing teams to create better products, faster. + +Importing and using code created elsewhere without vetting it introduces a +severe security risk.

Instead, these exporters write the +attestations to one or more JSON files in the root directory of the export. + +## Example + +The following example shows a truncated in-toto JSON representation of an SBOM +attestation. + +```json +{ + "_type": "https://in-toto.io/Statement/v0.1", + "predicateType": "https://spdx.dev/Document", + "subject": [ + { + "name": "pkg:docker//@?platform=", + "digest": { + "sha256": "e8275b2b76280af67e26f068e5d585eb905f8dfd2f1918b3229db98133cb4862" + } + } + ], + "predicate": { + "SPDXID": "SPDXRef-DOCUMENT", + "creationInfo": { + "created": "2022-12-15T11:47:54.546747383Z", + "creators": ["Organization: Anchore, Inc", "Tool: syft-v0.60.3"], + "licenseListVersion": "3.18" + }, + "dataLicense": "CC0-1.0", + "documentNamespace": "https://anchore.com/syft/dir/run/src/core-da0f600b-7f0a-4de0-8432-f83703e6bc4f", + "name": "/run/src/core", + // list of files that the image contains, e.g.: + "files": [ + { + "SPDXID": "SPDXRef-1ac501c94e2f9f81", + "comment": "layerID: sha256:9b18e9b68314027565b90ff6189d65942c0f7986da80df008b8431276885218e", + "fileName": "/bin/busybox", + "licenseConcluded": "NOASSERTION" + } + ], + // list of packages that were identified for this image: + "packages": [ + { + "name": "busybox", + "originator": "Person: SÃļren Tempel ", + "sourceInfo": "acquired package info from APK DB: lib/apk/db/installed", + "versionInfo": "1.35.0-r17", + "SPDXID": "SPDXRef-980737451f148c56", + "description": "Size optimized toolbox of many common UNIX utilities", + "downloadLocation": "https://busybox.net/", + "licenseConcluded": "GPL-2.0-only", + "licenseDeclared": "GPL-2.0-only" + // ... + } + ], + // files-packages relationship + "relationships": [ + { + "relatedSpdxElement": "SPDXRef-1ac501c94e2f9f81", + "relationshipType": "CONTAINS", + "spdxElementId": "SPDXRef-980737451f148c56" + }, + ... + ], + "spdxVersion": "SPDX-2.2" + } +} +``` + +To deep-dive into the specifics about how attestations are stored, see +[Image Attestation Storage (BuildKit)](attestation-storage.md). + +## Attestation manifest format + +Attestations are stored as manifests, referenced by the image's index.

Before +running the build, Buildx evaluates your policies against these +inputs. If any input violates a policy, the build fails before any +instructions execute. + +Policies are written in Rego, a declarative language designed for expressing +rules and constraints. You don't need to know Rego to get started - this +tutorial teaches you what you need. + +## Create your first policy + +Create a new directory for this tutorial and add a Dockerfile: + +```console +$ mkdir policy-tutorial +$ cd policy-tutorial +``` + +Create a `Dockerfile` that downloads a file with `ADD`: + +```dockerfile +FROM scratch +ADD https://example.com/index.html /index.html +``` + +Now create a policy file. Policies use the `.rego` extension and live alongside +your Dockerfile. Create `Dockerfile.rego`: + +```rego {title="Dockerfile.rego"} +package docker + +default allow := false + +allow if input.local +allow if { + input.http.host == "example.com" +} + +decision := {"allow": allow} +``` + +Save this file as `Dockerfile.rego` in the same directory as your Dockerfile. + +Let's break down what this policy does: + +- `package docker` - All build policies must start with this package declaration +- `default allow := false` - This example uses a deny-by-default rule: if inputs do not match an `allow` rule, the policy check fails +- `allow if input.local` - The first rule allows any local files (your build context) +- `allow if { input.http.host == "example.com" }` - The second rule allows HTTP downloads from `example.com` +- `decision := {"allow": allow}` - The final decision object tells Buildx whether to allow or deny the input + +This policy says: "Only allow local files and HTTP downloads from +`example.com`". Rego evaluates all the policy rules to figure out the return +value for the `decision` variable, for each build input. The evaluations happen +in parallel and on-demand; the order of the policy rules has no significance. + +### About `input.local` + +You'll see `allow if input.local` in nearly every policy. This rule allows +local file access, which includes your build context (typically, the `.` +directory) and importantly, the Dockerfile itself. Without this rule, Buildx +can't read your Dockerfile to start the build. + +Even builds that don't reference any files from the build context often need +`input.local` because the Dockerfile is a local file. The policy evaluates +before the build starts, and denying local access means denying access to the +Dockerfile. + +In rare cases, you might want stricter local file policies - for example, in CI +builds where the build context uses a Git URL as a context directly. In these +cases, you may want to deny local sources to prevent untracked files or changes +from making their way into your build. + +## Automatic policy loading + +Buildx automatically loads policies that match your Dockerfile name. When you +build with `Dockerfile`, Buildx looks for `Dockerfile.rego` in the same +directory. For a file named `app.Dockerfile`, it looks for +`app.Dockerfile.rego`. + +This automatic loading means you don't need any command-line flags in most +cases - create the policy file and build. + +The policy file must be in the same directory as the Dockerfile. If Buildx +can't find a matching policy, the build proceeds without policy evaluation +(unless you use `--policy strict=true`). + +For more control over policy loading, see the [Usage guide](./usage.md). + +## Run a build with your policy + +Build the image with policy evaluation enabled: + +```console +$ docker build . +``` + +The build succeeds because the URL in your Dockerfile matches the policy. Now +try changing the URL in your Dockerfile to something else: + +```dockerfile +FROM scratch +ADD https://api.github.com/users/octocat /user.json +``` + +Build again: + +```console +$ docker build . +``` + +This time the build fails with a policy violation. The `api.github.com` +hostname doesn't match the rule in your policy, so Buildx rejects it before +running any build steps. + +## Debugging policy failures + +If your build fails with a policy violation, use `--progress=plain` to see +exactly what went wrong: + +```console +$ docker buildx build --progress=plain . +``` + +This shows all policy checks, the input data for each source, and allow/deny +decisions. For complete debugging guidance, see [Debugging](./debugging.md). + +## Add helpful error messages + +When a policy denies an input, users see a generic error message. You can +provide custom messages that explain why the build was denied: + +```rego {title="Dockerfile.rego"} +package docker + +default allow := false + +allow if input.local +allow if { + input.http.host == "example.com" + input.http.schema == "https" +} + +deny_msg contains msg if { + not allow + input.http + msg := "only HTTPS downloads from example.com are allowed" +} + +decision := {"allow": allow, "deny_msg": deny_msg} +``` + +Now when a build is denied, users see your custom message explaining what went +wrong: + +```console +$ docker buildx build . +Policy: only HTTPS downloads from example.com are allowed +ERROR: failed to build: ... source not allowed by policy +``` + +The `deny_msg` rule uses `contains` to add messages to a set. You can add +multiple deny messages for different failure conditions to help users understand +exactly what needs to change. + +## Understand Rego rules + +Rego policies are built from rules. A rule defines when something is allowed. +The basic pattern is: + +```rego +allow if { + condition_one + condition_two + condition_three +} +``` + +All conditions must be true for the rule to match. Think of it as an AND +operation - the URL must match AND the checksum must match AND any other +conditions you specify. + +You can have multiple `allow` rules in one policy. If any rule matches, the +input is allowed: + +```rego +# Allow downloads from example.com +allow if { + input.http.host == "example.com" +} + +# Also allow downloads from api.github.com +allow if { + input.http.host == "api.github.com" +} +``` + +This works like OR - the input can match the first rule OR the second rule. + +## Access input fields + +The `input` object gives you access to information about build inputs. The +structure depends on the input type: + +- `input.http` - Files downloaded with `ADD https://...` +- `input.image` - Container images from `FROM` or `COPY --from` +- `input.git` - Git repositories from `ADD git://...` or build context +- `input.local` - Local file context + +Refer to the [Input reference](./inputs.md) for all available input fields. + +For HTTP downloads, you can access: + +| Key | Description | Example | +| ------------------- | ---------------------------------- | -------------------------------- | +| `input.http.url` | The full URL | `https://example.com/index.html` | +| `input.http.schema` | The protocol (HTTP/HTTPS) | `https` | +| `input.http.host` | The hostname | `example.com` | +| `input.http.path` | The URL path, including parameters | `/index.html` | + +Update your policy to require HTTPS: + +```rego +package docker + +default allow := false + +allow if { + input.http.host == "example.com" + input.http.schema == "https" +} + +decision := {"allow": allow} +``` + +Now the policy requires both the hostname to be `example.com` and the protocol +to be HTTPS. HTTP URLs (without TLS) would fail the policy check. + +## Pattern matching and strings + +Rego provides [built-in functions] for pattern matching. Use `startswith()` to +match URL prefixes: + +[built-in functions]: https://www.openpolicyagent.org/docs/policy-language#built-in-functions + +```rego +allow if { + startswith(input.http.url, "https://example.com/") +} +``` + +This allows any URL that starts with `https://example.com/`. + +Use `regex.match()` for complex patterns: + +```rego +allow if { + regex.match(`^https://example\.com/.+\.json$`, input.http.url) +} +``` + +This matches URLs that: + +- Start with `https://example.com/` +- End with `.json` +- Have at least one character between the domain and extension + +## Policy file location + +Policy files live adjacent to the Dockerfile they validate, using the naming +pattern `.rego`: + +```text +project/ +├── Dockerfile # Main Dockerfile +├── Dockerfile.rego # Policy for Dockerfile +├── lint.Dockerfile # Linting Dockerfile +└── lint.Dockerfile.rego # Policy for lint.Dockerfile +``` + +When you build, Buildx automatically loads the corresponding policy file: + +```console +$ docker buildx build -f Dockerfile . # Loads Dockerfile.rego +$ docker buildx build -f lint.Dockerfile . # Loads lint.Dockerfile.rego +``` + +## Next steps + +You now understand how to write basic build policies for HTTP resources.

Start with a basic deny-all policy. +2. Build with debug logging to see what inputs your Dockerfile uses. +3. Add rules to allow specific sources based on the debug output. +4. Test and refine. + +### Viewing inputs from your Dockerfile + +To see the inputs that your Dockerfile references (images, Git repos, HTTP +downloads), build with debug logging: + +```console +$ docker buildx build --progress=plain --policy log-level=debug . +``` + +Example output for an image source: + +```text +#1 0.010 checking policy for source docker-image://alpine:3.19 (linux/arm64) +#1 0.011 policy input: { +#1 0.011 "env": { +#1 0.011 "filename": "." +#1 0.011 }, +#1 0.011 "image": { +#1 0.011 "ref": "docker.io/library/alpine:3.19", +#1 0.011 "host": "docker.io", +#1 0.011 "repo": "alpine", +#1 0.011 "tag": "3.19", +#1 0.011 "platform": "linux/arm64" +#1 0.011 } +#1 0.011 } +#1 0.011 unknowns for policy evaluation: [input.image.checksum input.image.labels ...] +#1 0.012 policy decision for source docker-image://alpine:3.19: ALLOW +``` + +This shows the complete input structure, which fields are unresolved, and the +policy decision for each source. See [Input reference](./inputs.md) for all +available fields. + +### Testing policies with policy eval + +Use [`docker buildx policy eval`](/reference/cli/docker/buildx/policy/eval/) to +test whether your policy allows a specific source without running a full build. + +Note: `docker buildx policy eval` tests the source specified as the argument. +It doesn't parse your Dockerfile to evaluate all inputs - for that, [build with +--progress=plain](#viewing-inputs-from-your-dockerfile). + +Test if your policy allows the local context: + +```console +$ docker buildx policy eval . +``` + +No output means the policy allowed the source. If denied, you see: + +```console +ERROR: policy denied +``` + +Test other sources: + +```console +$ docker buildx policy eval https://example.com # Test HTTP +$ docker buildx policy eval https://github.com/org/repo.git # Test Git +``` + +By default, `--print` shows reference information parsed from the source string +(like `repo`, `tag`, `host`) without fetching from registries. To inspect +metadata that requires fetching the source (like `labels`, `checksum`, or +`hasProvenance`), specify which fields to fetch with `--fields`: + +```console +$ docker buildx policy eval --print --fields image.labels docker-image://alpine:3.19 +``` + +Multiple fields can be specified as a comma-separated list. + +### Iterative development example + +Here's a practical workflow for developing policies: + +1. Start with basic deny-all policy: + + ```rego {title="Dockerfile.rego"} + package docker + + default allow := false + + allow if input.local + + decision := {"allow": allow} + ``` + +2. Build with debug logging to see what inputs your Dockerfile uses: + + ```console + $ docker buildx build --progress=plain --policy log-level=debug . + ``` + + The output shows the denied image and its input structure: + + ```text + #1 0.026 checking policy for source docker-image://docker.io/library/alpine:3.19 + #1 0.027 policy input: { + #1 0.027 "image": { + #1 0.027 "repo": "alpine", + #1 0.027 "tag": "3.19", + #1 0.027 ... + #1 0.027 } + #1 0.027 } + #1 0.028 policy decision for source docker-image://alpine:3.19: DENY + #1 ERROR: source "docker-image://alpine:3.19" not allowed by policy + ``` + +3. Add a rule allowing the alpine image: + + ```rego + allow if { + input.image.repo == "alpine" + } + ``` + +4. Build again to verify the policy works: + + ```console + $ docker buildx build . + ``` + +If it fails, see [Debugging](./debugging.md) for troubleshooting guidance. + +## Using policies with `docker build` + +Once you've developed and tested your policy, apply it to real builds. + +### Basic usage + +Create a policy alongside your Dockerfile: + +```dockerfile {title="Dockerfile"} +FROM alpine:3.19 +RUN echo "hello" +``` + +```rego {title="Dockerfile.rego"} +package docker + +default allow := false + +allow if input.local + +allow if { + input.image.repo == "alpine" +} + +decision := {"allow": allow} +``` + +Build normally: + +```console +$ docker buildx build . +``` + +Buildx loads the policy automatically and validates the `alpine:3.19` image +before building. + +### Build with different Dockerfile names + +Specify the Dockerfile with `-f`: + +```console +$ docker buildx build -f app.Dockerfile . +``` + +Buildx looks for `app.Dockerfile.rego` in the same directory. + +### Build with manual policy + +Add an extra policy to the automatic one: + +```console +$ docker buildx build --policy filename=extra-checks.rego . +``` + +Both `Dockerfile.rego` (automatic) and `extra-checks.rego` (manual) must pass. + +### Build without automatic policy + +Use only your specified policy: + +```console +$ docker buildx build --policy reset=true,filename=strict.rego . +``` + +## Using policies with bake + +[Bake](/build/bake/) supports automatic policy loading just like `docker buildx +build`.

Use command-line flags instead: + +```console +$ docker buildx bake --policy disabled=true production +``` + +## Testing in CI/CD + +Validate policies in continuous integration by running builds with the `--policy` flag. For unit testing policies before running builds, see [Test build policies](./testing.md). + +Test policies during CI builds: + +```yaml {title=".github/workflows/test-policies.yml"} +name: Test Build Policies +on: [push, pull_request] + +jobs: + test: + runs-on: ubuntu-latest + steps: + - uses: actions/checkout@v4 + - uses: docker/setup-buildx-action@{{% param "setup_buildx_action_version" %}} + - name: Test build with policy + run: docker buildx build --policy strict=true . +``` + +This ensures policy changes don't break builds and that new rules work as +intended. The `strict=true` flag fails the build if policies aren't loaded (for +example, if the BuildKit instance used by the build is too old and doesn't +support policies). + +## Advanced: Policy configuration + +This section covers advanced policy loading mechanisms and configuration +options. + +### Automatic policy loading + +Buildx automatically loads policies that match your Dockerfile name. When you +build with `Dockerfile`, Buildx looks for `Dockerfile.rego` in the same +directory. For a file named `app.Dockerfile`, it looks for +`app.Dockerfile.rego`. + +```text +project/ +├── Dockerfile +├── Dockerfile.rego # Loaded automatically for Dockerfile +├── app.Dockerfile +├── app.Dockerfile.rego # Loaded automatically for app.Dockerfile +└── src/ +``` + +This automatic loading means you don't need command-line flags in most cases. +Create the policy file alongside your Dockerfile and build: + +```console +$ docker buildx build . +``` + +Buildx detects `Dockerfile.rego` and evaluates it before running the build. + +> [!NOTE] +> Policy files must be in the same directory as the Dockerfile they validate. +> Buildx doesn't search parent directories or subdirectories. + +### When policies don't load + +If buildx can't find a matching `.rego` file, the build proceeds without policy +evaluation. To require policies and fail if none are found, use strict mode: + +```console +$ docker buildx build --policy strict=true . +``` + +This fails the build if no policy loads or if the BuildKit daemon doesn't +support policies. + +### Manual policy configuration + +The `--policy` flag lets you specify additional policies, override automatic +loading, or control policy behavior. + +Basic syntax: + +```console +$ docker buildx build --policy filename=custom.rego . +``` + +This loads `custom.rego` in addition to the automatic `Dockerfile.rego` (if it +exists). + +Multiple policies: + +```console +$ docker buildx build --policy filename=policy1.rego --policy filename=policy2.rego . +``` + +All policies must pass for the build to succeed. Use this to enforce layered +requirements (base policy + project-specific rules). + +Available options: + +| Option | Description | Example | +| ------------------- | ------------------------------------------------------- | ----------------------------- | +| `filename=` | Load policy from specified file | `filename=custom.rego` | +| `reset=true` | Ignore automatic policies, use only specified ones | `reset=true` | +| `disabled=true` | Disable all policy evaluation | `disabled=true` | +| `strict=true` | Fail if BuildKit doesn't support policies | `strict=true` | +| `log-level=` | Control policy logging (error, warn, info, debug, none). Use `debug` to see complete input JSON and unresolved fields | `log-level=debug` | + +Combine options with commas: + +```console +$ docker buildx build --policy filename=extra.rego,strict=true . +``` + +### Exploring sources with policy eval + +The `docker buildx policy eval` command lets you quickly explore and test +sources without running a build. + +#### Inspect input structure with --print + +Use `--print` to see the input structure for any source without running policy +evaluation: + +```console +$ docker buildx policy eval --print https://github.com/moby/buildkit.git +``` + +```json +{ + "git": { + "schema": "https", + "host": "github.com", + "remote": "https://github.com/moby/buildkit.git" + } +} +``` + +Test different source types: + +```console +# HTTP downloads +$ docker buildx policy eval --print https://releases.hashicorp.com/terraform/1.5.0/terraform.zip + +# Images (requires docker-image:// prefix) +$ docker buildx policy eval --print docker-image://alpine:3.19 + +# Local context +$ docker buildx policy eval --print . +``` + +Shows information parsed from the source without fetching. Use `--fields` to +fetch specific metadata (see [above](#testing-policies-with-policy-eval)). + +#### Test with specific policy files + +The `--filename` flag specifies which policy file to load by providing the base +Dockerfile name (without the `.rego` extension). This is useful for testing +sources against policies associated with different Dockerfiles. + +For example, to test a source against the policy for `app.Dockerfile`: + +```console +$ docker buildx policy eval --filename app.Dockerfile . +``` + +This loads `app.Dockerfile.rego` and tests whether it allows the source `.` +(the local directory). The flag defaults to `Dockerfile` if not specified. + +Test different sources against your policy: + +```console +$ docker buildx policy eval --filename app.Dockerfile https://github.com/org/repo.git +$ docker buildx policy eval --filename app.Dockerfile docker-image://alpine:3.19 +``` + +### Reset automatic loading + +To use only your specified policies and ignore automatic `.rego` files: + +```console +$ docker buildx build --policy reset=true,filename=custom.rego . +``` + +This skips `Dockerfile.rego` and loads only `custom.rego`. + +### Disable policies temporarily + +Disable policy evaluation for testing or emergencies: + +```console +$ docker buildx build --policy disabled=true . +``` + +The build proceeds without any policy checks.

Templates are plain text files that use the [Go templating syntax](https://pkg.go.dev/text/template). This enables the insertion of logic and data, making the templates dynamic and adaptable according to the Compose model. + +When a template is executed, it must produce a YAML file which is the standard format for Kubernetes manifests. Multiple files can be generated as long as they are separated by `---` + +Each YAML output file begins with custom header notation, for example: + +```yaml +#! manifest.yaml +``` + +In the following example, a template iterates over services defined in a `compose.yaml` file.

Within the templates, data from the `compose.yaml` is accessed using dot notation, allowing you to navigate through nested data structures. For example, to access the deployment mode of a service, you would use `service.deploy.mode`: + + ```yaml +# iterate over a yaml sequence +{{ range $name, $service := .services }} + # access a nested attribute using dot notation + {{ if eq $service.deploy.mode "global" }} +kind: DaemonSet + {{ end }} +{{ end }} +``` + +You can check the [Compose Specification JSON schema](https://github.com/compose-spec/compose-go/blob/main/schema/compose-spec.json) for a full overview of the Compose model. This schema outlines all possible configurations and their data types in the Compose model. + +### Helper functions + +As part of the Go templating syntax, Compose Bridge offers a set of YAML helper functions designed to manipulate data within the templates efficiently: + +| Function | Description | +| ----------- | ----------------------------------------------------------------------------------------------------------- | +| `seconds` | Converts a [duration](/reference/compose-file/extension.md#specifying-durations) into an integer (seconds). | +| `uppercase` | Converts a string to uppercase. | +| `title` | Capitalizes the first letter of each word. | +| `safe` | Converts a string into a safe identifier (replaces non-lowercase characters with `-`). | +| `truncate` | Removes the first N elements from a list. | +| `join` | Joins list elements into a single string with a separator. | +| `base64` | Encodes a string as base64 (used for Kubernetes secrets). | +| `map` | Maps values using `“value -> newValue”` syntax. | +| `indent` | Indents string content by N spaces. | +| `helmValue` | Outputs a Helm-style template value. | + +In the following example, the template checks if a healthcheck interval is specified for a service, applies the `seconds` function to convert this interval into seconds and assigns the value to the `periodSeconds` attribute. + +```yaml +{{ if $service.healthcheck.interval }} + periodSeconds: {{ $service.healthcheck.interval | seconds }}{{ end }} +{{ end }} +``` + +## Customize the default templates + +As Kubernetes is a versatile platform, there are many ways +to map Compose concepts into Kubernetes resource definitions. Compose +Bridge lets you customize the transformation to match your own infrastructure +decisions and preferences, with varying level of flexibility and effort. + +### Modify the default templates + +You can extract templates used by the default transformation `docker/compose-bridge-kubernetes`: + +```console +$ docker compose bridge transformations create --from docker/compose-bridge-kubernetes my-template +``` + +The templates are extracted into a directory named after your template name, in this case `my-template`. It includes: + +- A Dockerfile that lets you create your own image to distribute your template +- A directory containing the templating files + +Edit, [add](#add-your-own-templates), or remove templates as needed. + +You can then use the generated Dockerfile to package your changes into a new transformation image, which you can then use with Compose Bridge: + +```console +$ docker build --tag mycompany/transform --push . +``` + +Use your transformation as a replacement: + +```console +$ docker compose bridge convert --transformations mycompany/transform +``` + +#### Model Runner templates + +The default transformation also includes templates for applications that use LLMs: + +- `model-runner-deployment.tmpl` +- `model-runner-service.tmpl` +- `model-runner-pvc.tmpl` +- `/overlays/model-runner/kustomization.yaml` +- `/overlays/desktop/deployment.tmpl` + +These templates can be extended or replaced to change how Docker Model Runner is deployed or configured. + +For more details, see [Use Model Runner](use-model-runner.md). + +### Add your own templates + +For resources that are not managed by Compose Bridge's default transformation, +you can build your own templates. + +The `compose.yaml` model may not offer all +the configuration attributes required to populate the target manifest. If this is the case, you can +then rely on Compose custom extensions to better describe the +application, and offer an agnostic transformation. + +For example, if you add `x-virtual-host` metadata +to service definitions in the `compose.yaml` file, you can use the following custom attribute +to produce Ingress rules: + +```yaml +{{ $project := .name }} +#! {{ $name }}-ingress.yaml +# Generated code, do not edit +apiVersion: networking.k8s.io/v1 +kind: Ingress +metadata: + name: virtual-host-ingress + namespace: {{ $project }} +spec: + rules: +{{ range $name, $service := .services }} +{{ range index $service "x-virtual-host" }} + - host: ${{ . }} + http: + paths: + - path: "/" + backend: + service: + name: ${{ name }} + port: + number: 80 +{{ end }} +{{ end }} +``` + +Once packaged into a Docker image, you can use this custom template +when transforming Compose models into Kubernetes in addition to other +transformations: + +```console +$ docker compose bridge convert \ + --transformation docker/compose-bridge-kubernetes \ + --transformation mycompany/transform +``` + +### Build your own transformation + +While Compose Bridge templates make it easy to customize with minimal changes, +you may want to make significant changes, or rely on an existing conversion tool. + +A Compose Bridge transformation is a Docker image that is designed to get a Compose model +from `/in/compose.yaml` and produce platform manifests under `/out`.

This means you need to pin `docker/cli v28.5.2+incompatible` to ensure compatibility and avoid build errors. + +### Example usage + +Here's a basic example demonstrating how to load a Compose project and start the services: + +```go +package main + +import ( + "context" + "log" + + "github.com/docker/cli/cli/command" + "github.com/docker/cli/cli/flags" + "github.com/docker/compose/v5/pkg/api" + "github.com/docker/compose/v5/pkg/compose" +) + +func main() { + ctx := context.Background() + + dockerCLI, err := command.NewDockerCli() + if err != nil { + log.Fatalf("Failed to create docker CLI: %v", err) + } + err = dockerCLI.Initialize(&flags.ClientOptions{}) + if err != nil { + log.Fatalf("Failed to initialize docker CLI: %v", err) + } + + // Create a new Compose service instance + service, err := compose.NewComposeService(dockerCLI) + if err != nil { + log.Fatalf("Failed to create compose service: %v", err) + } + + // Load the Compose project from a compose file + project, err := service.LoadProject(ctx, api.ProjectLoadOptions{ + ConfigPaths: []string{"compose.yaml"}, + ProjectName: "my-app", + }) + if err != nil { + log.Fatalf("Failed to load project: %v", err) + } + + // Start the services defined in the Compose file + err = service.Up(ctx, project, api.UpOptions{ + Create: api.CreateOptions{}, + Start: api.StartOptions{}, + }) + if err != nil { + log.Fatalf("Failed to start services: %v", err) + } + + log.Printf("Successfully started project: %s", project.Name) +} +``` + +This example demonstrates the core workflow - creating a service instance, loading a project from a Compose file, and +starting the services. The SDK provides many additional operations for managing the lifecycle of your containerized +application. + +## Customizing the SDK + +The `NewComposeService()` function accepts optional `compose.Option` parameters to customize the SDK behavior.

Its primary distinction is the introduction of an official [Go SDK](/manuals/compose/compose-sdk.md). This SDK provides a comprehensive API that lets you integrate Compose functionality directly into your applications, allowing you to load, validate, and manage multi-container environments without relying on the Compose CLI. To avoid confusion with the legacy Compose file formats labeled “v2” and “v3,” the versioning was advanced directly to v5. + +### Compose file format versioning + +The Docker Compose CLIs are defined by specific file formats. + +Three major versions of the Compose file format for Compose v1 were released: +- Compose file format 1 with Compose 1.0.0 in 2014 +- Compose file format 2.x with Compose 1.6.0 in 2016 +- Compose file format 3.x with Compose 1.10.0 in 2017 + +Compose file format 1 is substantially different to all the following formats as it lacks a top-level `services` key. +Its usage is historical and files written in this format don't run with Compose v2. + +Compose file format 2.x and 3.x are very similar to each other, but the latter introduced many new options targeted at Swarm deployments. + +To address confusion around Compose CLI versioning, Compose file format versioning, and feature parity depending on whether Swarm mode was in use, file format 2.x and 3.x were merged into the [Compose Specification](/reference/compose-file/_index.md). + +Compose v2 and v5 uses the Compose Specification for project definition. Unlike the prior file formats, the Compose Specification is rolling and makes the `version` top-level element optional. Compose v2 and v5 also makes use of optional specifications - [Deploy](/reference/compose-file/deploy.md), [Develop](/reference/compose-file/develop.md), and [Build](/reference/compose-file/build.md). + +To make migration easier, Compose v2 and v5 has backwards compatibility for certain elements that have been deprecated or changed between Compose file format 2.x/3.x and the Compose Specification. + +## What's next? + +- [How Compose works](compose-application-model.md) +- [Compose Specification reference](/reference/compose-file/_index.md) diff --git a/content/manuals/compose/release-notes.md b/content/manuals/compose/release-notes.md new file mode 100644 index 000000000000..aef0b8ae9022 --- /dev/null +++ b/content/manuals/compose/release-notes.md @@ -0,0 +1,7 @@ +--- +title: Release notes +weight: 80 +params: + sidebar: + goto: "https://github.com/docker/compose/releases" +--- \ No newline at end of file diff --git a/content/manuals/compose/support-and-feedback/_index.md b/content/manuals/compose/support-and-feedback/_index.md new file mode 100644 index 000000000000..175836c6b405 --- /dev/null +++ b/content/manuals/compose/support-and-feedback/_index.md @@ -0,0 +1,6 @@ +--- +build: + render: never +title: Support and feedback +weight: 70 +--- \ No newline at end of file diff --git a/content/manuals/compose/support-and-feedback/faq.md b/content/manuals/compose/support-and-feedback/faq.md new file mode 100644 index 000000000000..e6033ec5a9b7 --- /dev/null +++ b/content/manuals/compose/support-and-feedback/faq.md @@ -0,0 +1,111 @@ +--- +description: Answers to common questions about Docker Compose, including v1 vs v2, commands, shutdown behavior, and development setup. +keywords: docker compose faq, docker compose questions, docker-compose vs docker compose, docker compose json, docker compose stop delay, run multiple docker compose +title: Frequently asked questions about Docker Compose +linkTitle: FAQs +weight: 10 +tags: [FAQ] +aliases: +- /compose/faq/ +--- + +### What is the difference between `docker compose` and `docker-compose` + +Version one of the Docker Compose command-line binary was first released in 2014. It was written in Python, and is invoked with `docker-compose`. Typically, Compose v1 projects include a top-level version element in the `compose.yaml` file, with values ranging from 2.0 to 3.8, which refer to the specific file formats. + +Version two of the Docker Compose command-line binary was announced in 2020, is written in Go, and is invoked with `docker compose`. Compose v2 ignores the version top-level element in the compose.yaml file. + +For further information, see [History and development of Compose](/manuals/compose/intro/history.md). + +### What's the difference between `up`, `run`, and `start`? + +Typically, you want `docker compose up`. Use `up` to start or restart all the +services defined in a `compose.yaml`. In the default "attached" +mode, you see all the logs from all the containers. In "detached" mode (`-d`), +Compose exits after starting the containers, but the containers continue to run +in the background. + +The `docker compose run` command is for running "one-off" or "adhoc" tasks. It +requires the service name you want to run and only starts containers for services +that the running service depends on. Use `run` to run tests or perform +an administrative task such as removing or adding data to a data volume +container. The `run` command acts like `docker run -ti` in that it opens an +interactive terminal to the container and returns an exit status matching the +exit status of the process in the container. + +The `docker compose start` command is useful only to restart containers +that were previously created but were stopped. It never creates new +containers. + +### Why do my services take 10 seconds to recreate or stop? + +The `docker compose stop` command attempts to stop a container by sending a `SIGTERM`. It then waits +for a [default timeout of 10 seconds](/reference/cli/docker/compose/stop/). After the timeout, +a `SIGKILL` is sent to the container to forcefully kill it. If you +are waiting for this timeout, it means that your containers aren't shutting down +when they receive the `SIGTERM` signal. + +There has already been a lot written about this problem of +[processes handling signals](https://medium.com/@gchudnov/trapping-signals-in-docker-containers-7a57fdda7d86) +in containers. + +To fix this problem, try the following: + +- Make sure you're using the exec form of `CMD` and `ENTRYPOINT` +in your Dockerfile. + + For example use `["program", "arg1", "arg2"]` not `"program arg1 arg2"`. + Using the string form causes Docker to run your process using `bash` which + doesn't handle signals properly. Compose always uses the JSON form, so don't + worry if you override the command or entrypoint in your Compose file. + +- If you are able, modify the application that you're running to +add an explicit signal handler for `SIGTERM`. + +- Set the `stop_signal` to a signal which the application knows how to handle: + + ```yaml + services: + web: + build: . + stop_signal: SIGINT + ``` + +- If you can't modify the application, wrap the application in a lightweight init +system (like [s6](https://skarnet.org/software/s6/)) or a signal proxy (like +[dumb-init](https://github.com/Yelp/dumb-init) or +[tini](https://github.com/krallin/tini)). Either of these wrappers takes care of +handling `SIGTERM` properly. + +### How do I run multiple copies of a Compose file on the same host? + +Compose uses the project name to create unique identifiers for all of a +project's containers and other resources. To run multiple copies of a project, +set a custom project name using the `-p` command line option +or the [`COMPOSE_PROJECT_NAME` environment variable](/manuals/compose/how-tos/environment-variables/envvars.md#compose_project_name). + +### Can I use JSON instead of YAML for my Compose file? + +Yes. [YAML is a superset of JSON](https://stackoverflow.com/a/1729545/444646) so +any JSON file should be valid YAML. To use a JSON file with Compose, +specify the filename to use, for example: + +```console +$ docker compose -f compose.json up +``` + +### Should I include my code with `COPY`/`ADD` or a volume? + +You can add your code to the image using `COPY` or `ADD` directive in a +`Dockerfile`. This is useful if you need to relocate your code along with the +Docker image, for example when you're sending code to another environment +(production, CI, etc). + +Use a `volume` if you want to make changes to your code and see them +reflected immediately, for example when you're developing code and your server +supports hot code reloading or live-reload. + +There may be cases where you want to use both. You can have the image +include the code using a `COPY`, and use a `volume` in your Compose file to +include the code from the host during development. The volume overrides +the directory contents of the image. diff --git a/content/manuals/compose/support-and-feedback/feedback.md b/content/manuals/compose/support-and-feedback/feedback.md new file mode 100644 index 000000000000..494e821488b7 --- /dev/null +++ b/content/manuals/compose/support-and-feedback/feedback.md @@ -0,0 +1,18 @@ +--- +description: Find a way to provide feedback on Docker Compose that's right for you +keywords: Feedback, Docker Compose, Community forum, bugs, problems, issues +title: Give feedback +weight: 20 +aliases: +- /compose/feedback/ +--- + +There are many ways you can provide feedback on Docker Compose. + +### Report bugs or problems on GitHub + +To report bugs or problems, visit [Docker Compose on GitHub](https://github.com/docker/compose/issues) + +### Feedback via Community Slack channels + +You can also provide feedback through the `#docker-compose` [Docker Community Slack](https://dockr.ly/comm-slack) channel. diff --git a/content/manuals/desktop/_index.md b/content/manuals/desktop/_index.md new file mode 100644 index 000000000000..e2eef9cdd081 --- /dev/null +++ b/content/manuals/desktop/_index.md @@ -0,0 +1,80 @@ +--- +title: Docker Desktop +weight: 10 +description: Explore Docker Desktop, what it has to offer, and its key features.

Depending on your system configuration and operating system, Docker Desktop routes network and file operations between the Docker VM and the host using different backend components. + +### Backend components and responsibilities + +The backend acts as: + +- Network proxy: Translates traffic between the host and Linux VM. + - On Windows and Mac, this is handled by the `com.docker.backend` process. + - On Linux, the `qemu` process performs this function. +- File server: Handles file access from containers to the host filesystem. + - When using gRPC FUSE, the backend performs the file sharing. + - When using `virtiofs`, `osxfs`, or `krun`, file access is handled by those respective daemons rather than the backend process. +- Control plane: Manages Docker API calls, port forwarding, and proxy configuration. + +The following table summarizes typical setups in more detail: + +| Platform | Setup | Networking handled by | File sharing handled by | Notes | +| --------------- | ------------------------------------ | ------------------------ | -------------------------------------- | --------------------------------------------------------- | +| Windows | Hyper-V | `com.docker.backend.exe` | `com.docker.backend.exe` | Simplest setup with full visibility to EDR/firewall tools | +| Windows (WSL 2) | WSL 2 | `com.docker.backend.exe` | WSL 2 kernel (no visibility from host) | Recommended only when WSL 2 integration is needed | +| Mac | Virtualization framework + gRPC FUSE | `com.docker.backend` | `com.docker.backend` | Recommended for performance and visibility | +| Mac | Virtualization framework + `virtiofs`| `com.docker.backend` | Apple's Virtualization framework | Higher performance but no file access visibility from host| +| Mac | Virtualization framework + `osxfs` | `com.docker.backend` | `osxfs` | Legacy setup, not recommended | +| Mac | DockerVMM + `virtiofs` | `com.docker.backend` | `krun` | Currently in Beta | +| Linux | Native Linux VM | `qemu` | `virtiofsd` | No `com.docker.backend` process on Linux | + + +## How containers connect to the internet + +Each Linux container in Docker Desktop runs inside a small virtual network managed by Docker and every container is attached to a Docker-managed network and receives its own internal IP address. You can view and these networks with `docker network ls`, `docker network create`, and `docker network inspect`. They are managed by the [`daemon.json`](/manuals/engine/daemon/_index.md). + +When a container initiates a network request, for example with `apt-get update` or `docker pull`: + +- The container’s `eth0` interface connects to a virtual bridge (`docker0`) inside the VM. +- Outbound traffic from the container is sent through Network Address Translation (NAT) using a virtual adapter (typically with an internal IP such as `192.168.65.3`). You can view or change this with the [Docker Desktop settings](/manuals/desktop/settings-and-maintenance/settings.md#network). +- The traffic is transferred to the host system over a shared-memory channel rather than through a traditional virtual network interface. This approach ensures reliable communication and avoids conflicts with host-level network adapters or firewall configurations. +- On the host, Docker Desktop’s backend process receives the traffic and creates standard TCP/IP connections using the same networking APIs as other applications. + +All outbound container network traffic originates from the `com.docker.backend` process. Firewalls, VPNs, and security tools, like Crowdstrike, see traffic coming from this process — not from a VM or unknown source so firewall and endpoint security software can apply rules directly to `com.docker.backend`. + +## How exposed ports work + +When you publish a container port using the `-p` or `--publish` flag, Docker Desktop makes that container port accessible from your host system or local network. + +For example, with `docker run -p 80:80 nginx`: + +- Docker Desktop's backend process listens on the specified host port, in this case, port `80`. +- When an application such as a web browser connects to that port, Docker Desktop forwards the connection into the Linux VM where the container is running over a shared-memory channel. +- Inside the VM, the connection is routed to the container’s internal IP address and port, for example `172.17.0.2:80`. +- The container responds through the same path, so you can access it from your host just like any other local service. + +By default, `docker run -p` listens on all network interfaces (`0.0.0.0`), but you can restrict it to a specific address, such as `127.0.0.1` (`localhost`) or a particular network adapter. This behavior can be modified to bind to `localhost` by default in [Docker Desktop's network settings](/manuals/desktop/settings-and-maintenance/settings.md#network) + +Host firewalls can permit or deny inbound connections by filtering on `com.docker.backend`. + +## Using Docker Desktop with a proxy + +Docker Desktop can use your system’s default proxy settings or custom settings that you configure with [Docker Desktop's proxy setting](/manuals/desktop/settings-and-maintenance/settings.md#proxies). All proxy traffic passes through `com.docker.backend.exe`. + +When a proxy is enabled: + +- The backend process forwards the network requests, for example `docker pull`, through an internal proxy at `http.docker.internal:3128`. +- The internal proxy then connects either directly to the internet or through your upstream proxy, depending on your configuration and adding authentication if necessary. +- Docker Desktop then downloads the requested images or data through the proxy as usual. + +Note that: +- The proxy honors system or manual proxy configuration. +- On Windows, Basic, NTLM, and Kerberos authentication is supported. +- For Mac, NTLM/Kerberos is not supported natively. Run a local proxy on `localhost` as a workaround. +- CLI plugins and other tools that use the Docker API directly must be configured separately with the `HTTP_PROXY`, `HTTPS_PROXY`, and `NO_PROXY` environment variables. + +## Firewalls and endpoint visibility + +To restrict VM or container networking apply rules to `com.docker.backend.exe` (Windows) `com.docker.backend` (Mac) or `qemu` (Linux) as all VM networking is funneled through these processes. + +Use Windows Defender Firewall or enterprise endpoint firewalls for control. This enables traffic inspection and restriction at the host level without modifying the Docker Engine. + +Crowdstrike and similar tools can observe all traffic and file access that passes through the backend process. + +| Action | Visible to host EDR? | Reason | +|---------|----------------------|---------| +| Container reads host files | Yes | Access handled by `com.docker.backend` | +| Container writes host files | Yes | Same process performs the write | +| Container accesses its own filesystem layers | No | Exists only inside the VM | diff --git a/content/manuals/desktop/features/networking/networking-how-tos.md b/content/manuals/desktop/features/networking/networking-how-tos.md new file mode 100644 index 000000000000..f7ec059cf69f --- /dev/null +++ b/content/manuals/desktop/features/networking/networking-how-tos.md @@ -0,0 +1,190 @@ +--- +description: Learn how to connect containers to the host, across containers, or through proxies and VPNs in Docker Desktop. +keywords: docker desktop, networking, vpn, proxy, port mapping, dns +title: Explore networking how-tos on Docker Desktop +linkTitle: How-tos +aliases: +- /desktop/linux/networking/ +- /docker-for-mac/networking/ +- /mackit/networking/ +- /desktop/mac/networking/ +- /docker-for-win/networking/ +- /docker-for-windows/networking/ +- /desktop/windows/networking/ +- /desktop/networking/ +--- + +This page explains how to configure and use networking features, connect containers to host services, work behind proxies or VPNs, and troubleshoot common issues. + +For details on how Docker Desktop routes network traffic and file I/O between containers, the VM, and the host, see [Network overview](/manuals/desktop/features/networking/index.md#overview). + +## Core networking how-tos + +### Connect a container to a service on the host + +The host has a changing IP address, or none if you have no network access.

This is especially useful for editing source code in an IDE on +the host while running and testing the code in a container. + +#### Synchronized file shares + +Synchronized file shares is an alternative file sharing mechanism that provides fast and flexible host-to-VM file sharing, enhancing bind mount performance through the use of synchronized filesystem caches. Available with Pro, Team, and Business subscriptions. + +To learn more, see [Synchronized file share](/manuals/desktop/features/synchronized-file-sharing.md). + +#### Virtual file shares + +By default the `/Users`, `/Volumes`, `/private`, `/tmp` and `/var/folders` directory are shared. +If your project is outside this directory then it must be added to the list, +otherwise you may get `Mounts denied` or `cannot start service` errors at runtime. + +File share settings are: + +- **Add a Directory**. Select `+` and navigate to the directory you want to add. + +- **Remove a Directory**. Select `-` next to the directory you want to remove + +- **Apply** makes the directory available to containers using Docker's + bind mount (`-v`) feature. + +> [!TIP] +> +> * Share only the directories that you need with the container. File sharing +> introduces overhead as any changes to the files on the host need to be notified +> to the Linux VM. Sharing too many files can lead to high CPU load and slow +> filesystem performance. +> * Shared folders are designed to allow application code to be edited +> on the host while being executed in containers. For non-code items +> such as cache directories or databases, the performance will be much +> better if they are stored in the Linux VM, using a [data volume](/manuals/engine/storage/volumes.md) +> (named volume) or [data container](/manuals/engine/storage/volumes.md). +> * If you share the whole of your home directory into a container, MacOS may +> prompt you to give Docker access to personal areas of your home directory such as +> your Reminders or Downloads. +> * By default, Mac file systems are case-insensitive while Linux is case-sensitive. +> On Linux, it is possible to create two separate files: `test` and `Test`, +> while on Mac these filenames would actually refer to the same underlying +> file. This can lead to problems where an app works correctly on a developer's +> machine (where the file contents are shared) but fails when run in Linux in +> production (where the file contents are distinct). To avoid this, Docker Desktop +> insists that all shared files are accessed as their original case. Therefore, +> if a file is created called `test`, it must be opened as `test`. Attempts to +> open `Test` will fail with the error "No such file or directory". Similarly, +> once a file called `test` is created, attempts to create a second file called +> `Test` will fail. +> +> For more information, see [Volume mounting requires file sharing for any project directories outside of `/Users`](/manuals/desktop/troubleshoot-and-support/troubleshoot/topics.md) + +#### Shared folders on demand + +On Windows, you can share a folder "on demand" the first time a particular folder is used by a container. + +If you run a Docker command from a shell with a volume mount (as shown in the +example below) or kick off a Compose file that includes volume mounts, you get a +popup asking if you want to share the specified folder. + +You can select to **Share it**, in which case it is added to your Docker Desktop Shared Folders list and available to +containers. Alternatively, you can opt not to share it by selecting **Cancel**. + +![Shared folder on demand](../images/shared-folder-on-demand.png) + +### Proxies + +Docker Desktop supports the use of HTTP/HTTPS and SOCKS5 proxies (Requires a business subscription). + +HTTP/HTTPS and SOCKS5 proxies can be used when: + +- Signing in to Docker +- Pulling or pushing images +- Fetching artifacts during image builds +- Containers interact with the external network +- Scanning images + +For more details on how it works, see [Using Docker Desktop with a proxy](/manuals/desktop/features/networking/index.md#useing-docker-desktop-with-a-proxy). + +If the host uses a HTTP/HTTPS proxy configuration (static or via Proxy Auto-Configuration (PAC)), Docker Desktop reads +this configuration +and automatically uses these settings for signing in to Docker, for pulling and pushing images, and for +container Internet access. If the proxy requires authorization then Docker Desktop dynamically asks +the developer for a username and password. All passwords are stored securely in the OS credential store. +Note that only the `Basic` proxy authentication method is supported so we recommend using an `https://` +URL of your HTTP/HTTPS proxies to protect passwords while in transit on the network. Docker Desktop +supports TLS 1.3 when communicating with proxies. + +To set a different proxy for Docker Desktop, turn on **Manual proxy configuration** and enter a single +upstream proxy URL of the form `http://proxy:port` or `https://proxy:port`. + +To prevent developers from accidentally changing the proxy settings, see +[Settings Management](/manuals/enterprise/security/hardened-desktop/settings-management/_index.md#what-features-can-i-configure-with-settings-management). + +The HTTPS proxy settings used for scanning images are set using the `HTTPS_PROXY` environment variable. + +> [!NOTE] +> +> If you are using a PAC file hosted on a web server, make sure to add the MIME type `application/x-ns-proxy-autoconfig` for the `.pac` file extension on the server or website. Without this configuration, the PAC file may not be parsed correctly. For more details on PAC files and Docker Desktop, see [Hardened Docker Desktop](/manuals/enterprise/security/hardened-desktop/air-gapped-containers.md#proxy-auto-configuration-files) + +> [!IMPORTANT] +> You cannot configure the proxy settings using the Docker daemon configuration +> file (`daemon.json`), and we recommend you do not configure the proxy +> settings via the Docker CLI configuration file (`config.json`). +> +> To manage proxy configurations for Docker Desktop, configure the settings in +> the Docker Desktop app or use [Settings Management](/manuals/enterprise/security/hardened-desktop/settings-management/_index.md). + +#### Proxy authentication + +##### Basic authentication + +If your proxy uses Basic authentication, Docker Desktop prompts developers for a username and password and caches the credentials. All passwords are stored securely in the OS credential store. It will request re-authentication if that cache is removed. + +It's recommended that you use an `https://` URL of HTTP/HTTPS proxies to protect passwords during network transit. Docker Desktop also supports TLS 1.3 for communication with proxies. + +##### Kerberos and NTLM authentication + +> [!NOTE] +> +> Available for Docker Business subscribers with Docker Desktop for Windows version 4.30 and later. + +Developers are no longer interrupted by prompts for proxy credentials as authentication is centralized. This also reduces the risk of account lockouts due to incorrect sign in attempts. + +If your proxy offers multiple authentication schemes in 407 (Proxy Authentication Required) response, Docker Desktop by default selects the Basic authentication scheme. + +For Docker Desktop version 4.30 to 4.31: + +To enable Kerberos or NTLM proxy authentication, no additional configuration is needed beyond specifying the proxy IP address and port. + +For Docker Desktop version 4.32 and later: + +To enable Kerberos or NTLM proxy authentication you must pass the `--proxy-enable-kerberosntlm` installer flag during installation via the command line, and ensure your proxy server is properly configured for Kerberos or NTLM authentication. + +### Network + +> [!NOTE] +> +> On Windows, the **Network** tab isn't available in the Windows container mode because +> Windows manages networking. + +Docker Desktop uses a private IPv4 network for internal services such as a DNS server and an HTTP proxy. In case Docker Desktop's choice of subnet clashes with IPs in your environment, you can specify a custom subnet using the **Network** setting. + +On Windows and Mac, you can also set the default networking mode and DNS resolution behavior. For more information, see [Networking](/manuals/desktop/features/networking.md#networking-mode-and-dns-behaviour-for-mac-and-windows). + +On Mac, you can also select the **Use kernel networking for UDP** setting. This lets you use a more efficient kernel networking path for UDP. This may not be compatible with your VPN software. + +You can also define the behavior of port bindings. By default Docker Desktop binds all ports on containers to `0.0.0.0` on the host, though this can be overridden by providing a specific IP. You can change this default behavior by changing the **Port binding behavior** setting, allowing you to either bind to `localhost` (`127.0.0.1`) by default, or only allow containers to bind to `localhost` under any circumstances, even if requested otherwise. + +### WSL Integration + +On Windows in WSL 2 mode, you can configure which WSL 2 distributions will have the Docker +WSL integration. + +By default, the integration is enabled on your default WSL distribution. +To change your default WSL distribution, run `wsl --set-default `. (For example, +to set Ubuntu as your default WSL distribution, run `wsl --set-default ubuntu`). + +You can also select any additional distributions you would like to enable the WSL 2 integration on. + +For more details on configuring Docker Desktop to use WSL 2, see +[Docker Desktop WSL 2 backend](/manuals/desktop/features/wsl/_index.md). + +## Docker Engine + +The **Docker Engine** tab allows you to configure the Docker daemon used to run containers with Docker Desktop. + +You configure the daemon using a JSON configuration file. Here's what the file might look like: + +```json +{ + "builder": { + "gc": { + "defaultKeepStorage": "20GB", + "enabled": true + } + }, + "experimental": false +} +``` + +You can find this file at `$HOME/.docker/daemon.json`. To change the configuration, either +edit the JSON configuration directly from the dashboard in Docker Desktop, or open and +edit the file using your favorite text editor. + +To see the full list of possible configuration options, see the +[dockerd command reference](/reference/cli/dockerd/). + +Select **Apply** to save your settings. + +## Builders + +If you have turned on the +[Docker Desktop Builds view](/manuals/desktop/use-desktop/builds.md), you can use the +**Builders** tab to inspect and manage builders in the Docker Desktop settings. + +### Inspect + +To inspect builders, find the builder that you want to inspect and select the +expand icon.

To turn on Kubernetes support and +install a standalone instance of Kubernetes running as a Docker container, +select **Enable Kubernetes**. This can also be done from the **Kubernetes** view. + +You can choose your cluster provisioning method: + - **Kubeadm** creates a single-node cluster and the version is set by Docker Desktop. + - **kind** creates a multi-node cluster and you can set the version and number of nodes. + +Select **Show system containers (advanced)** to view internal containers when +using Docker commands. + +Select **Reset Kubernetes cluster** to delete all stacks and Kubernetes resources. + +For more information about using the Kubernetes integration with Docker Desktop, +see [Explore the Kubernetes view](/manuals/desktop/use-desktop/kubernetes.md). + +## Software updates + +The **Software updates** tab lets you manage your Docker Desktop updates. +When there's a new update, you can choose to download the update right away, or +select the **Release Notes** option to learn what's included in the updated version. + +The **Automatically check for updates** setting notifies you of any updates available to Docker Desktop in the Docker menu and the footer of the Docker Desktop Dashboard. This is turned on by default. + +To allow Docker Desktop to automatically download new updates in the background, +select **Always download updates**. This downloads newer versions of Docker Desktop +when an update becomes available. After downloading the update, select +**Apply and restart** to install the update. You can do this either through the +Docker menu or in the **Updates** section in the Docker Desktop Dashboard. + +The **Automatically update components** setting checks whether components of Docker Desktop, such as Docker Compose, Docker Scout, and the Docker CLI, can be updated independently without the need for a full restart.

It includes Docker Engine as this is the core technology that powers Docker containers. Docker Desktop for Linux also comes with additional features like Docker Scout and Docker Extensions. + +### Installing Docker Desktop and Docker Engine + +Docker Desktop for Linux and Docker Engine can be installed side-by-side on the +same machine. Docker Desktop for Linux stores containers and images in an isolated +storage location within a VM and offers +controls to restrict [its resources](/manuals/desktop/settings-and-maintenance/settings.md#resources). Using a dedicated storage +location for Docker Desktop prevents it from interfering with a Docker Engine +installation on the same machine. + +While it's possible to run both Docker Desktop and Docker Engine simultaneously, +there may be situations where running both at the same time can cause issues. +For example, when mapping network ports (`-p` / `--publish`) for containers, both +Docker Desktop and Docker Engine may attempt to reserve the same port on your +machine, which can lead to conflicts ("port already in use"). + +We generally recommend stopping the Docker Engine while you're using Docker Desktop +to prevent the Docker Engine from consuming resources and to prevent conflicts +as described above. + +Use the following command to stop the Docker Engine service: + +```console +$ sudo systemctl stop docker docker.socket containerd +``` + +Depending on your installation, the Docker Engine may be configured to automatically +start as a system service when your machine starts. Use the following command to +disable the Docker Engine service, and to prevent it from starting automatically: + +```console +$ sudo systemctl disable docker docker.socket containerd +``` + +### Switching between Docker Desktop and Docker Engine + +The Docker CLI can be used to interact with multiple Docker Engines. For example, +you can use the same Docker CLI to control a local Docker Engine and to control +a remote Docker Engine instance running in the cloud. [Docker Contexts](/manuals/engine/manage-resources/contexts.md) +allow you to switch between Docker Engines instances. + +When installing Docker Desktop, a dedicated "desktop-linux" context is created to +interact with Docker Desktop. On startup, Docker Desktop automatically sets its +own context (`desktop-linux`) as the current context. This means that subsequent +Docker CLI commands target Docker Desktop. On shutdown, Docker Desktop resets +the current context to the `default` context. + +Use the `docker context ls` command to view what contexts are available on your +machine. The current context is indicated with an asterisk (`*`). + +```console +$ docker context ls +NAME DESCRIPTION DOCKER ENDPOINT ... +default * Current DOCKER_HOST based configuration unix:///var/run/docker.sock ... +desktop-linux unix:///home//.docker/desktop/docker.sock ... +``` + +If you have both Docker Desktop and Docker Engine installed on the same machine, +you can run the `docker context use` command to switch between the Docker Desktop +and Docker Engine contexts. For example, use the "default" context to interact +with the Docker Engine: + +```console +$ docker context use default +default +Current context is now "default" +``` + +And use the `desktop-linux` context to interact with Docker Desktop: + +```console +$ docker context use desktop-linux +desktop-linux +Current context is now "desktop-linux" +``` + +Refer to the [Docker Context documentation](/manuals/engine/manage-resources/contexts.md) for more details. +{{< /accordion >}} + +## Supported platforms + +Docker provides `.deb` and `.rpm` packages for the following Linux distributions +and architectures: + +| Platform | x86_64 / amd64 | +| :----------------------------------------- | :------------: | +| [Ubuntu](ubuntu.md) | ✅ | +| [Debian](debian.md) | ✅ | +| [Red Hat Enterprise Linux (RHEL)](rhel.md) | ✅ | +| [Fedora](fedora.md) | ✅ | + +An experimental package is available for [Arch](archlinux.md)-based distributions. Docker has not tested or verified the installation. + +Docker supports Docker Desktop on the current LTS release of the aforementioned distributions and the most recent version. As new versions are made available, Docker stops supporting the oldest version and supports the newest version. + +## General system requirements + +To install Docker Desktop successfully, your Linux host must meet the following general requirements: + +- 64-bit kernel and CPU support for virtualization. +- KVM virtualization support. Follow the [KVM virtualization support instructions](#kvm-virtualization-support) to check if the KVM kernel modules are enabled and how to provide access to the KVM device. +- QEMU must be version 5.2 or later. We recommend upgrading to the latest version. +- systemd init system. +- GNOME, KDE, or MATE desktop environments are supported but others may work. + - For many Linux distributions, the GNOME environment does not support tray icons. To add support for tray icons, you need to install a GNOME extension. For example, [AppIndicator](https://extensions.gnome.org/extension/615/appindicator-support/). +- At least 4 GB of RAM. +- Enable configuring ID mapping in user namespaces, see [File sharing](/manuals/desktop/troubleshoot-and-support/faqs/linuxfaqs.md#how-do-i-enable-file-sharing). Note that for Docker Desktop version 4.35 and later, this is not required anymore. +- Recommended: [Initialize `pass`](/manuals/desktop/setup/sign-in.md#credentials-management-for-linux-users) for credentials management. + +Docker Desktop for Linux runs a Virtual Machine (VM). For more information on why, see [Why Docker Desktop for Linux runs a VM](/manuals/desktop/troubleshoot-and-support/faqs/linuxfaqs.md#why-does-docker-desktop-for-linux-run-a-vm). + +> [!NOTE] +> +> Docker does not provide support for running Docker Desktop for Linux in nested virtualization scenarios. We recommend that you run Docker Desktop for Linux natively on supported distributions. + +### KVM virtualization support + +Docker Desktop runs a VM that requires [KVM support](https://www.linux-kvm.org). + +The `kvm` module should load automatically if the host has virtualization support. To load the module manually, run: + +```console +$ modprobe kvm +``` + +Depending on the processor of the host machine, the corresponding module must be loaded: + +```console +$ modprobe kvm_intel # Intel processors + +$ modprobe kvm_amd # AMD processors +``` + +If the above commands fail, you can view the diagnostics by running: + +```console +$ kvm-ok +``` + +To check if the KVM modules are enabled, run: + +```console +$ lsmod | grep kvm +kvm_amd 167936 0 +ccp 126976 1 kvm_amd +kvm 1089536 1 kvm_amd +irqbypass 16384 1 kvm +``` + +#### Set up KVM device user permissions + +To check ownership of `/dev/kvm`, run : + +```console +$ ls -al /dev/kvm +``` + +Add your user to the kvm group in order to access the kvm device: + +```console +$ sudo usermod -aG kvm $USER +``` + +Sign out and sign back in so that your group membership is re-evaluated. + +## Using Docker SDKs with Docker Desktop + +Docker Desktop for Linux uses a per-user socket instead of the system-wide `/var/run/docker.sock`. Docker SDKs and tools that connect directly to the Docker daemon need the `DOCKER_HOST` environment variable set to connect to Docker Desktop.

Docker Desktop creates symlinks for the binaries in `/usr/local/bin`, which means they're automatically included in `PATH` on most systems. + +You can choose whether to install symlinks either in `/usr/local/bin` or `$HOME/.docker/bin` during installation of Docker Desktop. + +If `/usr/local/bin` is chosen, and this location is not writable by unprivileged users, Docker Desktop requires authorization to confirm this choice before the symlinks to Docker binaries are created in `/usr/local/bin`.

Creating this symlink ensures various Docker clients relying on the default Docker socket path work without additional changes. + +As the `/var/run` is mounted as a tmpfs, its content is deleted on restart, symlink to the Docker socket included. To ensure the Docker socket exists after restart, Docker Desktop sets up a `launchd` startup task that creates the symlink by running `ln -s -f /Users//.docker/run/docker.sock /var/run/docker.sock`. This ensures the you aren't prompted on each startup to create the symlink. If you don't enable this option at installation, the symlink and the startup task is not created and you may have to explicitly set the `DOCKER_HOST` environment variable to `/Users//.docker/run/docker.sock` in the clients it is using. The Docker CLI relies on the current context to retrieve the socket path, the current context is set to `desktop-linux` on Docker Desktop startup. + +### Binding privileged ports + +You can choose to enable privileged port mapping during installation, or from the **Advanced** page in **Settings** post-installation. Docker Desktop requires authorization to confirm this choice. + +### Ensuring `localhost` and `kubernetes.docker.internal` are defined + +It is your responsibility to ensure that localhost is resolved to `127.0.0.1` and if Kubernetes is used, that `kubernetes.docker.internal` is resolved to `127.0.0.1`. + +## Installing from the command line + +Privileged configurations are applied during the installation with the `--user` flag on the [install command](/manuals/desktop/setup/install/mac-install.md#install-from-the-command-line). In this case, you are not prompted to grant root privileges on the first run of Docker Desktop. Specifically, the `--user` flag: +- Uninstalls the previous `com.docker.vmnetd` if present +- Sets up symlinks +- Ensures that `localhost` is resolved to `127.0.0.1` + +The limitation of this approach is that Docker Desktop can only be run by one user-account per machine, namely the one specified in the `-–user` flag. + +## Privileged helper + +In the limited situations when the privileged helper is needed, for example binding privileged ports or caching the Registry Access Management policy, the privileged helper is started by `launchd` and runs in the background unless it is disabled at runtime as previously described.

Administrative rights are only required when absolutely necessary. + +## Permission requirements + +While Docker Desktop on Windows can be run without having `Administrator` privileges, it does require them during installation. On installation you receive a UAC prompt which allows a privileged helper service to be installed. After that, Docker Desktop can be run without administrator privileges. + +Running Docker Desktop on Windows without the privileged helper does not require users to have `docker-users` group membership. However, +some features that require privileged operations will have this requirement. + +If you performed the installation, you are automatically added to this group, but other users must be added manually. This allows the administrator to control who has access to features that require higher privileges, such as creating and managing the Hyper-V VM, or using Windows containers. + +When Docker Desktop launches, all non-privileged named pipes are created so that only the following users can access them: +- The user that launched Docker Desktop. +- Members of the local `Administrators` group. +- The `LOCALSYSTEM` account. + +## Privileged helper + +Docker Desktop needs to perform a limited set of privileged operations which are conducted by the privileged helper process `com.docker.service`. This approach allows, following the principle of least privilege, `Administrator` access to be used only for the operations for which it is absolutely necessary, while still being able to use Docker Desktop as an unprivileged user. + + +The privileged helper `com.docker.service` is a Windows service which runs in the background with `SYSTEM` privileges. It listens on the named pipe `//./pipe/dockerBackendV2`. The developer runs the Docker Desktop application, which connects to the named pipe and sends commands to the service. This named pipe is protected, and only users that are part of the `docker-users` group can have access to it. + +The service performs the following functionalities: +- Ensuring that `kubernetes.docker.internal` is defined in the Win32 hosts file. Defining the DNS name `kubernetes.docker.internal` allows Docker to share Kubernetes contexts with containers. +- Ensuring that `host.docker.internal` and `gateway.docker.internal` are defined in the Win32 hosts file. They point to the host local IP address and allow an application to resolve the host IP using the same name from either the host itself or a container. +- Securely caching the Registry Access Management policy which is read-only for the developer. +- Creating the Hyper-V VM `"DockerDesktopVM"` and managing its lifecycle - starting, stopping, and destroying it. The VM name is hard coded in the service code so the service cannot be used for creating or manipulating any other VMs. +- Moving the VHDX file or folder. +- Starting and stopping the Windows Docker engine and querying whether it's running. +- Deleting all Windows containers data files. +- Checking if Hyper-V is enabled. +- Checking if the bootloader activates Hyper-V. +- Checking if required Windows features are both installed and enabled. +- Conducting healthchecks and retrieving the version of the service itself. + +The service start mode depends on which container engine is selected, and, for WSL, on whether it is needed to maintain `host.docker.internal` and `gateway.docker.internal` in the Win32 hosts file. This is controlled by a setting under `Use the WSL 2 based engine` in the settings page. When this is set, WSL engine behaves the same as Hyper-V. So: +- With Windows containers, or Hyper-v Linux containers, the service is started when the system boots and runs all the time, even when Docker Desktop isn't running. This is required so you can launch Docker Desktop without admin privileges. +- With WSL2 Linux containers, the service isn't necessary and therefore doesn't run automatically when the system boots. When you switch to Windows containers or Hyper-V Linux containers, or choose to maintain `host.docker.internal` and `gateway.docker.internal` in the Win32 hosts file, a UAC prompt appears asking you to accept the privileged operation to start the service. If accepted, the service is started and set to start automatically upon the next Windows boot. + +## Containers running as root within the Linux VM + +The Linux Docker daemon and containers run in a minimal, special-purpose Linux +VM managed by Docker. It is immutable so you can’t extend it or change the +installed software. This means that although containers run by default as +`root`, this doesn't allow altering the VM and doesn't grant `Administrator` +access to the Windows host machine. The Linux VM serves as a security boundary +and limits what resources from the host can be accessed. File sharing uses a +user-space crafted file server and any directories from the host bind mounted +into Docker containers still retain their original permissions. Containers don't have access to any host files beyond those explicitly shared. + +## Enhanced Container Isolation + +In addition, Docker Desktop supports [Enhanced Container Isolation +mode](/manuals/enterprise/security/hardened-desktop/enhanced-container-isolation/_index.md) (ECI), +available to Business customers only, which further secures containers without +impacting developer workflows. + +ECI automatically runs all containers within a Linux user-namespace, such that +root in the container is mapped to an unprivileged user inside the Docker +Desktop VM. ECI uses this and other advanced techniques to further secure +containers within the Docker Desktop Linux VM, such that they are further +isolated from the Docker daemon and other services running inside the VM. + +## Windows containers + +> [!WARNING] +> +> Enabling Windows containers has important security implications. + +Unlike the Linux Docker Engine and containers which run in a VM, Windows containers are implemented using operating system features, and run directly on the Windows host. If you enable Windows containers during installation, the `ContainerAdministrator` user used for administration inside the container is a local administrator on the host machine.

To ensure that Docker Desktop provides a consistent experience across platforms. + + During research, the most frequently cited reason for users wanting Docker Desktop for Linux was to ensure a consistent Docker Desktop + experience with feature parity across all major operating systems. Utilizing + a VM ensures that the Docker Desktop experience for Linux users will closely + match that of Windows and macOS. + +2. To make use of new kernel features. + + Because Docker controls the kernel and the OS inside the VM, Docker can roll these out to all users immediately, even to users who are intentionally sticking on an LTS version of their machine OS. + +3. To enhance security. + + Container image vulnerabilities pose a security risk for the host environment. There is a large number of unofficial images that are not guaranteed to be verified for known vulnerabilities. Malicious users can push images to public registries and use different methods to trick users into pulling and running them. The VM approach mitigates this threat as any malware that gains root privileges is restricted to the VM environment without access to the host. + + Why not run rootless Docker? Although this has the benefit of superficially limiting access to the root user so everything looks safer in "top", it allows unprivileged users to gain `CAP_SYS_ADMIN` in their own user namespace and access kernel APIs which are not expecting to be used by unprivileged users, resulting in [vulnerabilities](https://www.openwall.com/lists/oss-security/2022/01/18/7). + +4. To provide the benefits of feature parity and enhanced security, with minimal impact on performance. + + The VM utilized by Docker Desktop for Linux uses [`VirtioFS`](https://virtio-fs.gitlab.io), a shared file system that allows virtual machines to access a directory tree located on the host. Docker's internal benchmarking shows that with the right resource allocation to the VM, near native file system performance can be achieved with VirtioFS. + + As such, the default memory available to the VM in Docker Desktop for Linux is adjusted. You can tweak this setting to your specific needs by using the **Memory** slider within the **Settings** > **Resources** tab of Docker Desktop. + +### How do I enable file sharing? + +Docker Desktop for Linux uses [VirtioFS](https://virtio-fs.gitlab.io/) as the +default (and currently only) mechanism to enable file sharing between the host +and Docker Desktop VM. + +{{< accordion title="Additional information for Docker Desktop version 4.34 and earlier" >}} + +In order not to require elevated privileges, without +unnecessarily restricting operations on the shared files, Docker Desktop runs +the file sharing service (`virtiofsd`) inside a user namespace (see +`user_namespaces(7)`) with UID and GID mapping configured. As a result Docker +Desktop relies on the host being configured to enable the current user to use +subordinate ID delegation. For this to be true `/etc/subuid` (see `subuid(5)`) +and `/etc/subgid` (see `subgid(5)`) must be present. Docker Desktop only +supports subordinate ID delegation configured via files. Docker Desktop maps the +current user ID and GID to 0 in the containers. It uses the first entry +corresponding to the current user in `/etc/subuid` and `/etc/subgid` to set up +mappings for IDs greater than 0 in the containers. + +| ID in container | ID on host | +| --------------- | -------------------------------------------------------------------------------- | +| 0 (root) | ID of the user running Docker Desktop (e.g. 1000) | +| 1 | 0 + beginning of ID range specified in `/etc/subuid`/`/etc/subgid` (e.g. 100000) | +| 2 | 1 + beginning of ID range specified in `/etc/subuid`/`/etc/subgid` (e.g. 100001) | +| 3 | 2 + beginning of ID range specified in `/etc/subuid`/`/etc/subgid` (e.g. 100002) | +| ... | ... | + +If `/etc/subuid` and `/etc/subgid` are missing, they need to be created. +Both should contain entries in the form - +`::`. For example, to allow the current user +to use IDs from 100 000 to 165 535: + +```console +$ grep "$USER" /etc/subuid >> /dev/null 2&>1 || (echo "$USER:100000:65536" | sudo tee -a /etc/subuid) +$ grep "$USER" /etc/subgid >> /dev/null 2&>1 || (echo "$USER:100000:65536" | sudo tee -a /etc/subgid) +``` + +To verify the configs have been created correctly, inspect their contents: + +```console +$ echo $USER +exampleuser +$ cat /etc/subuid +exampleuser:100000:65536 +$ cat /etc/subgid +exampleuser:100000:65536 +``` + +In this scenario if a shared file is `chown`ed inside a Docker Desktop container +owned by a user with a UID of 1000, it shows up on the host as owned by +a user with a UID of 100999. This has the unfortunate side effect of preventing +easy access to such a file on the host. The problem is resolved by creating +a group with the new GID and adding our user to it, or by setting a recursive +ACL (see `setfacl(1)`) for folders shared with the Docker Desktop VM. + +{{< /accordion >}} + +### How do I use Docker SDKs with Docker Desktop for Linux? + +Docker Desktop for Linux uses a per-user socket located at `~/.docker/desktop/docker.sock` instead of the system-wide `/var/run/docker.sock`. The Docker CLI handles this automatically through the `desktop-linux` context, but Docker SDKs and other tools that connect directly to the Docker daemon also need the `DOCKER_HOST` environment variable set. + +Without setting `DOCKER_HOST`, SDKs attempt to connect to `/var/run/docker.sock` and fail with an error like: + +```text +Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running? +``` + +To fix this, set the `DOCKER_HOST` environment variable before running your SDK-based application: + +```console +export DOCKER_HOST=unix://$HOME/.docker/desktop/docker.sock +``` + +Or dynamically retrieve it from the `desktop-linux` context: + +```console +export DOCKER_HOST=$(docker context inspect desktop-linux --format '{{ .Endpoints.docker.Host }}') +``` + +To make this permanent, add the export command to your shell profile (`~/.bashrc`, `~/.zshrc`, or similar): + +```console +echo 'export DOCKER_HOST=unix://$HOME/.docker/desktop/docker.sock' >> ~/.bashrc +``` + +### Where does Docker Desktop store Linux containers? + +Docker Desktop stores Linux containers and images in a single, large "disk image" file in the Linux filesystem.

If Windows style line endings +are used, `docker run` fails with syntax errors. + +#### Solution + + - Convert files to Unix-style line endings using: + + ```console + $ dos2unix script.sh + ``` +- In VS Code, set line endings to `LF` (Unix) instead of `CRLF` (Windows). + +### Path conversion errors on Windows + +#### Cause + +Unlike Linux, Windows requires explicit path conversion for volume mounting. + + +On Linux, the system takes care of mounting a path to another path. For example, when you run the following command on Linux: + +```console +$ docker run --rm -ti -v /home/user/work:/work alpine +``` + +It adds a `/work` directory to the target container to mirror the specified path. + +#### Solution + +Update the source path. For example, if you are using +the legacy Windows shell (`cmd.exe`), you can use the following command: + +```console +$ docker run --rm -ti -v C:\Users\user\work:/work alpine +``` + +This starts the container and ensures the volume becomes usable. This is possible because Docker Desktop detects +the Windows-style path and provides the appropriate conversion to mount the directory. + +Docker Desktop also allows you to use Unix-style path to the appropriate format. For example: + +```console +$ docker run --rm -ti -v /c/Users/user/work:/work alpine ls /work +``` + +### Docker commands failing in Git Bash + +#### Error message + +```console +$ docker run --rm -ti -v C:\Users\user\work:/work alpine +docker: Error response from daemon: mkdir C:UsersUserwork: Access is denied. +``` + +```console +$ docker run --rm -ti -v $(pwd):/work alpine +docker: Error response from daemon: OCI runtime create failed: invalid mount {Destination:\Program Files\Git\work Type:bind Source:/run/desktop/mnt/host/c/Users/user/work;C Options:[rbind rprivate]}: mount destination \Program Files\Git\work not absolute: unknown. +``` + +#### Cause + +Git Bash (or MSYS) provides a Unix-like environment on Windows. These tools apply their own +preprocessing on the command line. + +This affects `$(pwd)`, colon-separated paths, and tilde (`~`) + +Also, the `\` character has a special meaning in Git Bash. + +#### Solution + + - Disable Git Bash path conversion temporarily. For example, run the command with MSYS path conversion disable: + ```console + $ MSYS_NO_PATHCONV=1 docker run --rm -ti -v $(pwd):/work alpine + ``` + - Use proper path formatting: + - Use double forward and backslashes (`\\` `//`) instead of single (`\` `/`). + - If referencing `$(pwd)`, add an extra `/`: + +Portability of the scripts is not affected as Linux treats multiple `/` as a single entry. + +### Docker Desktop fails due to Virtualization not working + +#### Error message + +A typical error message is "Docker Desktop - Unexpected WSL error" mentioning the error code +`Wsl/Service/RegisterDistro/CreateVm/HCS/HCS_E_HYPERV_NOT_INSTALLED`.

The Docker Desktop installer enables +it for you. + +Docker Desktop also needs two CPU hardware features to use Hyper-V: Virtualization and Second Level Address Translation (SLAT), which is also called Rapid Virtualization Indexing (RVI). On some systems, Virtualization must be enabled in the BIOS. The steps required are vendor-specific, but typically the BIOS option is called `Virtualization Technology (VTx)` or something similar. Run the command `systeminfo` to check all required Hyper-V features.

For images, this lets you select a base image, add packages, +add OCI artifacts (such as custom certificates or additional tools), and +configure settings. For charts, this lets you customize the image references. + +Your customizations stay secure automatically. When the base Docker Hardened +Image or chart receives a security patch or your OCI artifacts are updated, +Docker automatically rebuilds your customizations in the background.

The rebuilt artifacts are signed and attested to the same SLSA Build +Level 3 standard as the base images and charts, ensuring a secure and verifiable +supply chain. + +## Customize a Docker Hardened Image + +To add a customized Docker Hardened Image to your organization, an organization +owner must first [mirror](./mirror.md) the DHI repository to your organization +on Docker Hub. Once the repository is mirrored, any user with access to the +mirrored DHI repository can create a customized image. + +### Create an image customization + +To customize a Docker Hardened Image, follow these steps: + +1. Sign in to [Docker Hub](https://hub.docker.com). +1. Select **My Hub**. +1. In the namespace drop-down, select your organization that has a mirrored DHI + repository. +1. Select **Hardened Images** > **Manage** > **Mirrored Images**. +1. For the mirrored DHI repository you want to customize, select the menu icon in the far right column. +1. Select **Customize**. + + At this point, the on-screen instructions will guide you through the + customization process. You can continue with the following steps for more + details. + +1. Select the image version you want to customize. +1. Optional. Add packages. + + 1. In the **Packages** drop-down, select the packages you want to add to the + image. + + The packages available in the drop-down are OS system packages for the + selected image variant. For example, if you are customizing the Alpine + variant of the Python DHI, the list will include all Alpine system + packages. + + 1. In the **OCI artifacts** drop-down, first, select the repository that + contains the OCI artifact image. Then, select the tag you want to use from + that repository. Finally, specify the specific paths you want to include + from the OCI artifact image. + + The OCI artifacts are images that you have previously + built and pushed to a repository in the same namespace as the mirrored + DHI. For example, you can add a custom root CA certificate or a another + image that contains a tool you need, like adding Python to a Node.js + image. For more details on how to create an OCI artifact image, see + [Create an OCI artifact image](#create-an-oci-artifact-image-for-image-customization). + + When combining images that contain directories and files with the same + path, images later in the list will overwrite files from earlier images. + To manage this, you must select paths to include and optionally exclude + from each OCI artifact image. This allows you to control which files are + included in the final customized image. + + By default, no files are included from the OCI artifact image. You must + explicitly include the paths you want. After including a path, you can + then explicitly exclude files or directories underneath it. + + > [!NOTE] + > + > When files necessary for runtime are overwritten by OCI artifacts, the + > image build still succeeds, but you may have issues when running the + > image. + + 1. In the **Scripts** section, you can add, edit, or remove scripts. + + Scripts let you add files to the container image that you can access at runtime. They are not executed during + the build process. This is useful for services that require pre-start initialization, such as setup scripts or + file writes to directories like `/var/lock` or `/out`. + + You must specify the following: + + - The path where the script will be placed + - The script content + - The UID and GID ownership of the script + - The octal file permissions of the script + +1. Select **Next: Configure** to configure the following image settings: + + 1. Specify the [environment variables](/reference/dockerfile/#env) and their + values that the image will contain. + 1. Add [labels](/reference/dockerfile/#label) to the image. + 1. Add [annotations](/build/metadata/annotations/) to the image. + 1. Specify the users to add to the image. + 1. Specify the user groups to add to the image. + 1. Select which [user](/reference/dockerfile/#user) to run the images as. + 1. Add [`ENTRYPOINT`](/reference/dockerfile/#entrypoint) arguments to the + image. These arguments are appended to the base image's entrypoint. + 1. Add [`CMD`](/reference/dockerfile/#cmd) arguments to the image. These + arguments are appended to the base image's command. + 1. Override the default (`/`) [working + directory](/reference/dockerfile/#workdir) for the image. + 1. Specify a suffix for the customization name that is appended to the + customized image's tag. For example, if you specify `custom` when + customizing the `dhi-python:3.13` image, the customized image will be + tagged as `dhi-python:3.13_custom`. + 1. Select the platforms you want to build the image for. You must select at + least one platform. + +1. Select **Next: Review customization**. + +1. Select **Create Customization**. + + A summary of the customization appears. It may take some time for the image + to build. Once built, it will appear in the **Tags** tab of the repository, + and your team members can pull it like any other image. + +### Create an OCI artifact image for image customization + +An OCI artifact image is a Docker image that contains files or directories that +you want to include in your customized Docker Hardened Image (DHI). This can +include additional tools, libraries, or configuration files. + +When creating an image to use as an OCI artifact, it should ideally be as +minimal as possible and contain only the necessary files. + +For example, to distribute a custom root CA certificate as part of a trusted CA +bundle, you can use a multi-stage build. This approach registers your +certificate with the system and outputs an updated CA bundle, which can be +extracted into a minimal final image: + +```dockerfile +# syntax=docker/dockerfile:1 + +FROM dhi.io/bash:5-dev AS certs + +ENV DEBIAN_FRONTEND=noninteractive + +RUN mkdir -p /usr/local/share/ca-certificates/my-rootca +COPY certs/rootCA.crt /usr/local/share/ca-certificates/my-rootca + +RUN update-ca-certificates + +FROM scratch +COPY --from=certs /etc/ssl/certs/ca-certificates.crt /etc/ssl/certs/ca-certificates.crt +``` + +You can follow this pattern to create other OCI artifacts, such as images +containing tools or libraries that you want to include in your customized DHI. +Install the necessary tools or libraries in the first stage, and then copy the +relevant files to the final stage that uses `FROM scratch`. This ensures that +your OCI artifact is minimal and contains only the necessary files. + +In order for the OCI artifact to be available in a DHI customization, it must be built and +pushed to a repository in the same namespace as the mirrored DHI repository. + +If you're customizing a DHI for multiple platforms (such as `linux/amd64` and +`linux/arm64`), build your OCI artifact for all the platforms using the +`--platform` flag: + +```console +$ docker buildx build --platform linux/amd64,linux/arm64 \ + -t /my-oci-artifact:latest \ + --push . +``` + +This creates a single image manifest that you can use for each platform. The +customization build system automatically selects the correct platform variant +when building each customized image. + +> [!IMPORTANT] +> +> The customization UI will only allow you to select platforms that are +> available in all OCI artifacts you've added. If a platform is missing from +> any OCI artifact, you won't be able to select that platform for your +> customization. + +Once pushed to a repository in your organization's namespace, the OCI artifact +automatically appears in the customization workflow when you select OCI +artifacts to add to your customized Docker Hardened Image. + +#### Best practices for OCI artifacts + +Follow these best practices when creating OCI artifacts for DHI customizations: + +- Use multi-stage builds: Build or install dependencies in a builder stage, + then copy only the necessary files to a `FROM scratch` final stage. This keeps + the OCI artifact minimal and free of unnecessary build tools. + +- Include only essential files: OCI artifacts should contain only the files + you need to add to the customized image. Avoid including package managers, + shells, or other utilities that won't be used in the final image. + +- Match target platforms: Build your OCI artifact for all platforms you plan + to use in your customizations. Use `docker buildx build --platform` to create + multi-platform images when needed. + +- Use specific tags: Tag your OCI artifacts with specific versions or dates + (like `v1.0` or `20250101`) rather than relying solely on `latest`. This + ensures reproducible builds and makes it easier to track which artifacts are + used in which customizations. + +- Enable immutable tags: Consider enabling [immutable + tags](../../docker-hub/repos/manage/hub-images/immutable-tags.md) for your + OCI artifact repositories. This prevents accidental overwrites and ensures that + each version of your OCI artifact remains unchanged, improving reproducibility + and reliability of your customizations. + +## Customize a DHI Helm chart + +You can customize DHI Helm charts to meet your organization's specific needs. +Via the Docker Hub web interface, you can modify the image references to +reference mirrored images or customized images you've created. This lets you +create a custom, securely-built chart with references to images stored in Docker +Hub or other private registries. DHI securely packages customized Helm charts +that reference your repositories, wherever they are stored, by default. + +To customize image references, an organization owner must [mirror](./mirror.md) +the DHI chart repository to your organization on Docker Hub. + +You can create one chart customization per Helm chart repository. This is +different from image customizations, where you can create multiple +customizations per repository. If you need to make changes, you can edit your +existing customization. Alternatively, you can mirror the same Helm chart +repository again and add a new customization to the new mirror. + +> [!NOTE] +> +> You can customize Docker Hardened Image charts like any other Helm chart using +> standard Helm tools and practices, such as a `values.yaml` file, outside of +> Docker Hub. The following instructions describe how to customize image +> references for the chart using the Docker Hub web interface. + +To customize a Docker Hardened Image Helm chart after it has been mirrored: + +1.

Once mirrored, the repository +becomes available in your organization's namespace, and you can customize it as +needed. + +To mirror a Docker Hardened Image repository: + +1. Go to [Docker Hub](https://hub.docker.com) and sign in. +2. Select **My Hub**. +3. In the namespace drop-down, select your organization. +4. Select **Hardened Images** > **Catalog**. +5.

You can still use the last images or charts that were mirrored, +but the repository will not receive new tags or updates from the original +repository. + +> [!NOTE] +> +> If you only want to stop mirroring ELS versions, you can uncheck the ELS +> option in the mirrored repository's **Settings** tab. For more details, see +> [Disable ELS for a repository](./els.md#disable-els-for-a-repository). + + To stop mirroring a repository: + +1. Go to [Docker Hub](https://hub.docker.com) and sign in. +2. Select **My Hub**. +3. In the namespace drop-down, select your organization that has access to DHI. +4. Select **Hardened Images** > **Manage**. +5. Select the **Mirrored Images** or **Mirrored Helm charts** tab. +6. In the far right column of the repository you want to stop mirroring, select the menu icon. +7. Select **Stop mirroring**. + +## Mirror a DHI repository to a third-party registry + +You can optionally mirror a DHI repository to another container registry, such as Amazon +ECR, Google Artifact Registry, GitHub Container Registry, or a private Harbor +instance. + +You can use any standard workflow to mirror the image, such as the +[Docker CLI](/reference/cli/docker/), [Docker Hub Registry +API](/reference/api/registry/latest/), third-party registry tools, or CI/CD +automation. + +However, to preserve the full security context, including attestations, you must +also mirror its associated OCI artifacts. DHI repositories store the image +layers on `dhi.io` (or `docker.io` for customized images) and the signed +attestations in a separate registry (`registry.scout.docker.com`). + +To copy both, you can use [`regctl`](https://regclient.org/cli/regctl/), an +OCI-aware CLI that supports mirroring images along with attached artifacts such +as SBOMs, vulnerability reports, and SLSA provenance. For ongoing synchronization, +you can use [`regsync`](https://regclient.org/cli/regsync/). + +### Example mirroring with `regctl` + +The following example shows how to mirror a specific tag of a Docker Hardened +Image from Docker Hub to another registry, along with its associated +attestations using `regctl`. You must [install +`regctl`](https://github.com/regclient/regclient) first. + +The example assumes you have mirrored the DHI repository to your organization's +namespace on Docker Hub as described in the previous section. You can apply the +same steps to a non-mirrored image by updating the the `SRC_ATT_REPO` and +`SRC_REPO` variables accordingly. + +1. Set environment variables for your specific environment. Replace the + placeholders with your actual values. + + In this example, you use a Docker username to represent a member of the Docker + Hub organization that the DHI repositories are mirrored in. Prepare a + [personal access token (PAT)](../../security/access-tokens.md) for the user + with `read only` access. Alternatively, you can use an organization namespace and + an [organization access token + (OAT)](../../enterprise/security/access-tokens.md) to sign in to Docker Hub, but OATs + are not yet supported for `registry.scout.docker.com`. + + ```console + $ export DOCKER_USERNAME="YOUR_DOCKER_USERNAME" + $ export DOCKER_PAT="YOUR_DOCKER_PAT" + $ export DOCKER_ORG="YOUR_DOCKER_ORG" + $ export DEST_REG="registry.example.com" + $ export DEST_REPO="mirror/dhi-python" + $ export DEST_REG_USERNAME="YOUR_DESTINATION_REGISTRY_USERNAME" + $ export DEST_REG_TOKEN="YOUR_DESTINATION_REGISTRY_TOKEN" + $ export SRC_REPO="docker.io/${DOCKER_ORG}/dhi-python" + $ export SRC_ATT_REPO="registry.scout.docker.com/${DOCKER_ORG}/dhi-python" + $ export TAG="3.13-alpine3.21" + ``` + +2. Sign in via `regctl` to Docker Hub, the Scout registry that contains + the attestations, and your destination registry. + + ```console + $ echo $DOCKER_PAT | regctl registry login -u "$DOCKER_USERNAME" --pass-stdin docker.io + $ echo $DOCKER_PAT | regctl registry login -u "$DOCKER_USERNAME" --pass-stdin registry.scout.docker.com + $ echo $DEST_REG_TOKEN | regctl registry login -u "$DEST_REG_USERNAME" --pass-stdin "$DEST_REG" + ``` + +3. Mirror the image and attestations using `--referrers` and referrer endpoints: + + ```console + $ regctl image copy \ + "${SRC_REPO}:${TAG}" \ + "${DEST_REG}/${DEST_REPO}:${TAG}" \ + --referrers \ + --referrers-src "${SRC_ATT_REPO}" \ + --referrers-tgt "${DEST_REG}/${DEST_REPO}" \ + --force-recursive + ``` + +4. Verify that artifacts were preserved. + + First, get a digest for a specific tag and platform. For example, `linux/amd64`. + + ```console + DIGEST="$(regctl manifest head "${DEST_REG}/${DEST_REPO}:${TAG}" --platform linux/amd64)" + ``` + + List attached artifacts (SBOM, provenance, VEX, vulnerability reports). + + ```console + $ regctl artifact list "${DEST_REG}/${DEST_REPO}@${DIGEST}" + ``` + + Or, list attached artifacts with `docker scout`. + + ```console + $ docker scout attest list "registry://${DEST_REG}/${DEST_REPO}@${DIGEST}" + ``` + +### Example ongoing mirroring with `regsync` + +`regsync` automates pulling from your organizations mirrored DHI repositories on +Docker Hub and pushing to your external registry including attestations. It +reads a YAML configuration file and can filter tags. + +The following example uses a `regsync.yaml` file that syncs Node 24 and Python +3.12 Debian 13 variants, excluding Alpine and Debian 12. + +```yaml{title="regsync.yaml"} +version: 1 +# Optional: inline creds if not relying on prior CLI logins +# creds: +# - registry: docker.io +# user: +# pass: "{{file \"/run/secrets/docker_token\"}}" +# - registry: registry.scout.docker.com +# user: +# pass: "{{file \"/run/secrets/docker_token\"}}" +# - registry: registry.example.com +# user: +# pass: "{{file \"/run/secrets/dest_token\"}}" + +sync: + - source: docker.io//dhi-node + target: registry.example.com/mirror/dhi-node + type: repository + fastCopy: true + referrers: true + referrerSource: registry.scout.docker.com//dhi-node + referrerTarget: registry.example.com/mirror/dhi-node + tags: + allow: [ "24.*" ] + deny: [ ".*alpine.*", ".*debian12.*" ] + + - source: docker.io//dhi-python + target: registry.example.com/mirror/dhi-python + type: repository + fastCopy: true + referrers: true + referrerSource: registry.scout.docker.com//dhi-python + referrerTarget: registry.example.com/mirror/dhi-python + tags: + allow: [ "3.12.*" ] + deny: [ ".*alpine.*", ".*debian12.*" ] +``` + +To do a dry run with the configuration file, you can run the following command. +You must [install `regsync`](https://github.com/regclient/regclient) first. + +```console +$ regsync check -c regsync.yaml +``` + +To run the sync with the configuration file: + +```console +$ regsync once -c regsync.yaml +``` + +## What next + +After mirroring, see [Pull a DHI](./use.md#pull-a-dhi) to learn how to pull and use mirrored images. diff --git a/content/manuals/dhi/how-to/policies.md b/content/manuals/dhi/how-to/policies.md new file mode 100644 index 000000000000..80f9589bc024 --- /dev/null +++ b/content/manuals/dhi/how-to/policies.md @@ -0,0 +1,115 @@ +--- +title: Enforce Docker Hardened Image usage with policies +linktitle: Enforce image usage +description: Learn how to use image policies with Docker Scout for Docker Hardened Images. +weight: 50 +keywords: docker scout policies, enforce image compliance, container security policy, image provenance, vulnerability policy check +--- + +When you have a Docker Hardened Images Enterprise subscription, mirroring a +Docker Hardened Image (DHI) repository automatically enables [Docker +Scout](/scout/), allowing you to start enforcing security and compliance +policies for your images without additional setup.

For example: + +```console +$ docker run --rm dhi.io/python:3.13 python -c "print('Hello from DHI')" +``` + +## Use a DHI in CI/CD pipelines + +Docker Hardened Images work just like any other image in your CI/CD pipelines. +You can reference them in Dockerfiles, pull them as part of a pipeline step, or +run containers based on them during builds and tests. + +Unlike typical container images, DHIs also include signed +[attestations](../core-concepts/attestations.md) such as SBOMs and provenance +metadata. You can incorporate these into your pipeline to support supply chain +security, policy checks, or audit requirements if your tooling supports it. + +To strengthen your software supply chain, consider adding your own attestations +when building images from DHIs. This lets you document how the image was +built, verify its integrity, and enable downstream validation and policy +enforcement using tools like Docker Scout. + +To learn how to attach attestations during the build process, see [Docker Build +Attestations](/manuals/build/metadata/attestations.md). + +## Use a static image for compiled executables + +Docker Hardened Images include a `static` image repository designed specifically +for running compiled executables in an extremely minimal and secure runtime. + +Unlike a non-hardened `FROM scratch` image, the DHI `static` image includes all +the attestations needed to verify its integrity and provenance. Although it is +minimal, it includes the common packages needed to run containers securely, such +as `ca-certificates`. + +Use a `-dev` or other builder image in an earlier stage to compile your binary, +and copy the output into a `static` image. + +The following example shows a multi-stage Dockerfile that builds a Go application +and runs it in a minimal static image: + +```dockerfile +#syntax=docker/dockerfile:1 + +FROM dhi.io/golang:1.22-dev AS build +WORKDIR /app +COPY . . +RUN CGO_ENABLED=0 go build -o myapp + +FROM dhi.io/static:20230311 +COPY --from=build /app/myapp /myapp +ENTRYPOINT ["/myapp"] +``` + +This pattern ensures a hardened runtime environment with no unnecessary +components, reducing the attack surface to a bare minimum. + +## Use dev variants for framework-based applications + +If you're building applications with frameworks that require package managers or +build tools (such as Python, Node.js, or Go), use a `-dev` variant during the +development or build stage. These variants include essential utilities like +shells, compilers, and package managers to support local iteration and CI +workflows. + +Use `-dev` images in your inner development loop or in isolated CI stages to +maximize productivity. Once you're ready to produce artifacts for production, +switch to a smaller runtime variant to reduce the attack surface and image size. + +Dev variants are typically configured with no `ENTRYPOINT` and a default `CMD` that +launches a shell (for example, ["/bin/bash"]). In those cases, running the +container without additional arguments starts an interactive shell by default. + +The following example shows how to build a Python app using a `-dev` variant and +run it using the smaller runtime variant: + +```dockerfile +#syntax=docker/dockerfile:1 + +FROM dhi.io/python:3.13-alpine3.21-dev AS builder + +ENV LANG=C.UTF-8 +ENV PYTHONDONTWRITEBYTECODE=1 +ENV PYTHONUNBUFFERED=1 +ENV PATH="/app/venv/bin:$PATH" + +WORKDIR /app + +RUN python -m venv /app/venv +COPY requirements.txt . + +RUN pip install --no-cache-dir -r requirements.txt + +FROM dhi.io/python:3.13-alpine3.21 + +WORKDIR /app + +ENV PYTHONUNBUFFERED=1 +ENV PATH="/app/venv/bin:$PATH" + +COPY image.py image.png ./ +COPY --from=builder /app/venv /app/venv + +ENTRYPOINT [ "python", "/app/image.py" ] +``` + +This pattern separates the build environment from the runtime environment, +helping reduce image size and improve security by removing unnecessary tooling +from the final image. + +## Use compliance variants {tier="DHI Enterprise"} + +{{< summary-bar feature_name="Docker Hardened Images" >}} + +When you have a Docker Hardened Images Enterprise subscription, you can access +compliance variants such as FIPS-enabled and STIG-ready images.

As +such, they typically don't include a shell or standard debugging tools. The +recommended way to troubleshoot containers built on DHIs is by using [Docker +Debug](./how-to/debug.md). + +Docker Debug allows you to: + +- Attach a temporary debug container to your existing container. +- Use a shell and familiar tools such as `curl`, `ps`, `netstat`, and `strace`. +- Install additional tools as needed in a writable, ephemeral layer that + disappears after the session. + +## Permissions + +DHIs run as a nonroot user by default for enhanced security. This can result in +permission issues when accessing files or directories. Ensure your application +files and runtime directories are owned by the expected UID/GID or have +appropriate permissions. + +To find out which user a DHI runs as, check the repository page for the image on +Docker Hub. See [View image variant +details](./how-to/explore.md#view-image-variant-details) for more information. + +## Privileged ports + +Nonroot containers cannot bind to ports below 1024 by default. This is enforced +by both the container runtime and the kernel (especially in Kubernetes and +Docker Engine < 20.10). + +Inside the container, configure your application to listen on an unprivileged +port (1025 or higher). For example `docker run -p 80:8080 my-image` maps +port 8080 in the container to port 80 on the host, allowing you to access it +without needing root privileges. + +## No shell + +Runtime DHIs omit interactive shells like `sh` or `bash`. If your build or +tooling assumes a shell is present (e.g., for `RUN` instructions), use a `dev` +variant of the image in an earlier build stage and copy the final artifact into +the runtime image. + +To find out which shell, if any, a DHI has, check the repository page for the +image on Docker Hub. See [View image variant +details](./how-to/explore.md#view-image-variant-details) for more information. + +Also, use [Docker Debug](./how-to/debug.md) when you need shell +access to a running container. + +## Entry point differences + +DHIs may define different entry points compared to Docker Official Images (DOIs) +or other community images. + +To find out the ENTRYPOINT or CMD for a DHI, check the repository page for the +image on Docker Hub.

As a result, they don't include a package manager such as `apk` or +`apt`. This means you can't install additional software directly in the runtime +image. + +If your build or application setup requires installing packages (for example, to +compile code, install runtime dependencies, or add diagnostic tools), use a `dev` +variant of the image in a build stage.

Advanced users can benefit from more specialized +image variants as well as review Docker Official Images as part of your +`Dockerfile` learning process. + +> [!NOTE] +> +> Use of Docker Official Images is subject to [Docker's Terms of Service](https://www.docker.com/legal/docker-terms-service/). + +These images provide essential base repositories that serve as the starting +point for the majority of users. + +These include operating systems such as +[Ubuntu](https://hub.docker.com/_/ubuntu/) and +[Alpine](https://hub.docker.com/_/alpine/), programming language runtimes such as +[Python](https://hub.docker.com/_/python) and +[Node](https://hub.docker.com/_/node), and other essential tools such as +[memcached](https://hub.docker.com/_/memcached) and +[MySQL](https://hub.docker.com/_/mysql). + +The images are some of the [most secure images](https://www.docker.com/blog/enhancing-security-and-transparency-with-docker-official-images/) +on Docker Hub. This is particularly important as Docker Official Images are +some of the most popular on Docker Hub. Typically, Docker Official images have +few or no packages containing CVEs. + +The images exemplify [Dockerfile best practices](/manuals/build/building/best-practices.md) +and provide clear documentation to serve as a reference for other Dockerfile authors. + +Images that are part of this program have a special badge on Docker Hub making +it easier for you to identify projects that are part of Docker Official Images. + +![Docker official image badge](../images/official-image-badge-iso.png) + +### Supported tags and respective Dockerfile links + +The repository description for each Docker Official Image contains a +**Supported tags and respective Dockerfile links** section that lists all the +current tags with links to the Dockerfiles that created the image with those +tags. The purpose of this section is to show what image variants are available. + +![Example: supported tags for Ubuntu](../images/supported_tags.webp) + +Tags listed on the same line all refer to the same underlying image. Multiple +tags can point to the same image. For example, in the previous screenshot taken +from the `ubuntu` Docker Official Images repository, the tags `24.04`, +`noble-20240225`, `noble`, and `devel` all refer to the same image. + +The `latest` tag for a Docker Official Image is often optimized for ease of use +and includes a wide variety of useful software, such as developer and build tools. +By tagging an image as `latest`, the image maintainers are essentially suggesting +that image be used as the default. In other words, if you do not know what tag to +use or are unfamiliar with the underlying software, you should probably start with +the `latest` image. As your understanding of the software and image variants advances, +you may find other image variants better suit your needs. + +### Slim images + +A number of language stacks such as +[Node.js](https://hub.docker.com/_/node/), +[Python](https://hub.docker.com/_/python/), and +[Ruby](https://hub.docker.com/_/ruby/) have `slim` tag variants +designed to provide a lightweight, production-ready base image +with fewer packages. + +A typical consumption pattern for `slim` +images is as the base image for the final stage of a +[multi-staged build](https://docs.docker.com/build/building/multi-stage/). +For example, you build your application in the first stage of the build +using the `latest` variant and then copy your application into the final +stage based upon the `slim` variant. Here is an example `Dockerfile`. + +```dockerfile +FROM node:latest AS build +WORKDIR /app +COPY package.json package-lock.json ./ +RUN npm ci +COPY . ./ +FROM node:slim +WORKDIR /app +COPY --from=build /app /app +CMD ["node", "app.js"] +``` + +### Alpine images + +Many Docker Official Images repositories also offer `alpine` variants. These +images are built on top of the [Alpine Linux](https://www.alpinelinux.org/) +distribution rather than Debian or Ubuntu. Alpine Linux is focused on providing +a small, simple, and secure base for container images, and Docker Official +Images `alpine` variants typically aim to install only necessary packages. As a +result, Docker Official Images `alpine` variants are typically even smaller +than `slim` variants. + +The main caveat to note is that Alpine Linux uses [musl libc](https://musl.libc.org/) +instead of [glibc](https://www.gnu.org/software/libc/). Additionally, to +minimize image size, it's uncommon for Alpine-based images to include tools +such as Git or Bash by default. Depending on the depth of libc requirements or +assumptions in your programs, you may find yourself running into issues due to +missing libraries or tools. + +When you use Alpine images as a base, consider the following options in order +to make your program compatible with Alpine Linux and musl: + +- Compile your program against musl libc +- Statically link glibc libraries into your program +- Avoid C dependencies altogether (for example, build Go programs without CGO) +- Add the software you need yourself in your Dockerfile. + +Refer to the `alpine` image [description](https://hub.docker.com/_/alpine) on +Docker Hub for examples on how to install packages if you are unfamiliar. + +### Codenames + +Tags with words that look like Toy Story characters (for example, `bookworm`, +`bullseye`, and `trixie`) or adjectives (such as `jammy`, and +`noble`), indicate the codename of the Linux distribution they use as a base +image. Debian release codenames are [based on Toy Story characters](https://en.wikipedia.org/wiki/Debian_version_history#Naming_convention), +and Ubuntu's take the form of "Adjective Animal". For example, the +codename for Ubuntu 24.04 is "Noble Numbat". + +Linux distribution indicators are helpful because many Docker Official Images +provide variants built upon multiple underlying distribution versions (for +example, `postgres:bookworm` and `postgres:bullseye`). + +### Other tags + +Docker Official Images tags may contain other hints to the purpose of +their image variant in addition to those described here. Often these +tag variants are explained in the Docker Official Images repository +documentation. Reading through the "How to use this image" and +"Image Variants" sections will help you to understand how to use these +variants. + +### Troubleshooting failed pulls + +If you're experiencing failed pulls of Docker Official Images, check whether +the `DOCKER_CONTENT_TRUST` environment variable is set to `1`. Starting in +August 2025, Docker Content Trust signing certificates for Docker Official +Images began expiring. To resolve pull failures, unset the `DOCKER_CONTENT_TRUST` +environment variable. For more details, see the +[DCT retirement blog post](https://www.docker.com/blog/retiring-docker-content-trust/). + +## Verified Publisher images + +The Docker Verified Publisher program provides high-quality images from +commercial publishers verified by Docker. + +These images help development teams build secure software supply chains, +minimizing exposure to malicious content early in the process to save time and +money later. + +Images that are part of this program have a special badge on Docker Hub making +it easier for users to identify projects that Docker has verified as +high-quality commercial publishers. + +![Docker-Verified Publisher badge](../images/verified-publisher-badge-iso.png) + +## Docker-Sponsored Open Source Software images + +The Docker-Sponsored Open Source Software (OSS) program provides images that are +published and maintained by open-source projects sponsored by Docker. + +Images that are part of this program have a special badge on Docker Hub making +it easier for users to identify projects that Docker has verified as trusted, +secure, and active open-source projects. + +![Docker-Sponsored Open Source

This team works in +collaboration with upstream software maintainers, security experts, and the +broader Docker community. + +While it's preferable to have upstream software authors maintaining their +Docker Official Images, this isn't a strict requirement. Creating +and maintaining images for Docker Official Images is a collaborative process. +It takes place [openly on GitHub](https://github.com/docker-library/official-images) +where participation is encouraged. Anyone can provide feedback, contribute +code, suggest process changes, or even propose a new Official Image. + +## Creating a Docker Official Image + +From a high level, an Official Image starts out as a proposal in the form +of a set of GitHub pull requests. The following GitHub repositories detail the proposal requirements: + +- [Docker Official Images repository on GitHub](https://github.com/docker-library/official-images#readme) +- [Documentation for Docker Official Images](https://github.com/docker-library/docs#readme) + +The Docker Official Images team, with help from community contributors, formally +review each proposal and provide feedback to the author. This initial review +process can be lengthy, often requiring a bit of back-and-forth before the proposal is accepted. + +There are subjective considerations during the review process. These +subjective concerns boil down to the basic question: "is this image generally +useful?" For example, the [Python](https://hub.docker.com/_/python/) +Docker Official Image is "generally useful" to the larger Python developer +community, whereas an obscure text adventure game written in Python last week is +not. + +Once a new proposal is accepted, the author is responsible for keeping their +images and documentation up-to-date and responding to user feedback. Docker is +responsible for building and publishing the images on Docker Hub. Updates to +Docker Official Images follow the same pull request process as for new images, +although the review process for updates is more streamlined. The Docker Official +Images team ultimately acts as a gatekeeper for all changes, which helps +ensures consistency, quality, and security. + +## Submitting feedback for Docker Official Images + +All Docker Official Images contain a **User Feedback** section in their +documentation which covers the details for that specific repository. In most +cases, the GitHub repository which contains the Dockerfiles for an Official +Image also has an active issue tracker. + +General feedback and support questions about Docker Official Images +should be directed to the `#general` channel in the [Docker Community Slack](https://dockr.ly/comm-slack). + +If you're a maintainer or contributor to Docker Official Images and you're +looking for help or advice, use the `#docker-library` channel on [Libera.Chat IRC](https://libera.chat). diff --git a/content/manuals/docker-hub/repos/manage/vulnerability-scanning.md b/content/manuals/docker-hub/repos/manage/vulnerability-scanning.md new file mode 100644 index 000000000000..9a21813daa46 --- /dev/null +++ b/content/manuals/docker-hub/repos/manage/vulnerability-scanning.md @@ -0,0 +1,204 @@ +--- +description: Learn about vulnerability scanning and Docker Scout image analysis in Docker Hub. +keywords: scanning, vulnerabilities, Hub, static +title: Image security insights +weight: 70 +aliases: +- /docker-hub/vulnerability-scanning/ +--- + +Strengthen the security of your Docker images with Docker Hub's image security +insights.

If you specify a `hosts` entry in the `daemon.json`, this causes a +configuration conflict and results in the Docker daemon failing to start. + +To work around this problem, create a new file +`/etc/systemd/system/docker.service.d/docker.conf` with the following contents, +to remove the `-H` argument that's used when starting the daemon by default. + +```systemd +[Service] +ExecStart= +ExecStart=/usr/bin/dockerd +``` + +There are other times when you might need to configure `systemd` with Docker, +such as [configuring a HTTP or HTTPS proxy](./proxy.md). + +> [!NOTE] +> +> If you override this option without specifying a `hosts` entry in the +> `daemon.json` or a `-H` flag when starting Docker manually, Docker fails to +> start. + +Run `sudo systemctl daemon-reload` before attempting to start Docker.

To prevent this from +happening, ensure that your application runs on hosts with adequate memory and +see +[Understand the risks of running out of memory](../containers/resource_constraints.md#understand-the-risks-of-running-out-of-memory). + +### Kernel compatibility + +Docker can't run correctly if your kernel is older than version 3.10, or if it's +missing kernel modules. To check kernel compatibility, you can download and run +the +[`check-config.sh`](https://raw.githubusercontent.com/docker/docker/master/contrib/check-config.sh) +script. + +```console +$ curl https://raw.githubusercontent.com/docker/docker/master/contrib/check-config.sh > check-config.sh + +$ bash ./check-config.sh +``` + +The script only works on Linux. + +### Kernel cgroup swap limit capabilities + +On Ubuntu or Debian hosts, you may see messages similar to the following when +working with an image. + +```text +WARNING: Your kernel does not support swap limit capabilities.

Memory and swap accounting incur an overhead of about 1% of the +total available memory and a 10% overall performance degradation, even when +Docker isn't running. + +1. Log into the Ubuntu or Debian host as a user with `sudo` privileges. + +2. Edit the `/etc/default/grub` file. Add or edit the `GRUB_CMDLINE_LINUX` line + to add the following two key-value pairs: + + ```text + GRUB_CMDLINE_LINUX="cgroup_enable=memory swapaccount=1" + ``` + + Save and close the file. + +3. Update the GRUB boot loader. + + ```console + $ sudo update-grub + ``` + + An error occurs if your GRUB configuration file has incorrect syntax. In this + case, repeat steps 2 and 3. + + The changes take effect when you reboot the system. + +## Networking + +### IP forwarding problems + +If you manually configure your network using `systemd-network` with systemd +version 219 or later, Docker containers may not be able to access your network. +Beginning with systemd version 220, the forwarding setting for a given network +(`net.ipv4.conf..forwarding`) defaults to off. This setting prevents +IP forwarding. It also conflicts with Docker's behavior of enabling the +`net.ipv4.conf.all.forwarding` setting within containers. + +To work around this on RHEL, CentOS, or Fedora, edit the `.network` +file in `/usr/lib/systemd/network/` on your Docker host, for example, +`/usr/lib/systemd/network/80-container-host0.network`. + +Add the following block within the `[Network]` section. + +```systemd +[Network] +... +IPForward=kernel +# OR +IPForward=true +``` + +This configuration allows IP forwarding from the container as expected. + +### DNS resolver issues + +```console +DNS resolver found in resolv.conf and containers can't use it +``` + +Linux desktop environments often have a network manager program running, that +uses `dnsmasq` to cache DNS requests by adding them to `/etc/resolv.conf`. The +`dnsmasq` instance runs on a loopback address such as `127.0.0.1` or +`127.0.1.1`. It speeds up DNS look-ups and provides DHCP services. Such a +configuration doesn't work within a Docker container. The Docker container uses +its own network namespace, and resolves loopback addresses such as `127.0.0.1` +to itself, and it's unlikely to be running a DNS server on its own loopback +address. + +If Docker detects that no DNS server referenced in `/etc/resolv.conf` is a fully +functional DNS server, the following warning occurs: + +```text +WARNING: Local (127.0.0.1) DNS resolver found in resolv.conf and containers +can't use it. Using default external servers : [8.8.8.8 8.8.4.4] +``` + +If you see this warning, first check to see if you use `dnsmasq`: + +```console +$ ps aux | grep dnsmasq +``` + +If your container needs to resolve hosts which are internal to your network, the +public nameservers aren't adequate. You have two choices: + +- Specify DNS servers for Docker to use. +- Turn off `dnsmasq`. + + Turning off `dnsmasq` adds the IP addresses of actual DNS nameservers to + `/etc/resolv.conf`, and you lose the benefits of `dnsmasq`. + +You only need to use one of these methods. + +### Specify DNS servers for Docker + +The default location of the configuration file is `/etc/docker/daemon.json`. You +can change the location of the configuration file using the `--config-file` +daemon flag.

Create or edit the Docker daemon configuration file, which defaults to + `/etc/docker/daemon.json` file, which controls the Docker daemon + configuration. + + ```console + $ sudo nano /etc/docker/daemon.json + ``` + +2.

When you run a +container without the `--network` option, it is connected to the default +bridge. + +Containers attached to the default bridge have access to network services +outside the Docker host.

They cannot refer to each other by name. + +It can be useful to separate groups of containers that should have full +access to each other, but restricted access to containers in other groups. + +You can create custom, user-defined networks, and connect groups of containers +to the same network. Once connected to a user-defined network, containers +can communicate with each other using container IP addresses or container names. + +The following example creates a network using the `bridge` network driver and +runs a container in that network: + +```console +$ docker network create -d bridge my-net +$ docker run --network=my-net -it busybox +``` + +### Drivers + +Docker Engine has a number of network drivers, as well as the default "bridge". +On Linux, the following built-in network drivers are available: + +| Driver | Description | +|:--------------------------------|:--------------------------------------------------------------------| +| [bridge](./drivers/bridge.md) | The default network driver. | +| [host](./drivers/host.md) | Remove network isolation between the container and the Docker host. | +| [none](./drivers/none.md) | Completely isolate a container from the host and other containers. | +| [overlay](./drivers/overlay.md) | Swarm Overlay networks connect multiple Docker daemons together. | +| [ipvlan](./drivers/ipvlan.md) | Connect containers to external VLANs. | +| [macvlan](./drivers/macvlan.md) | Containers appear as devices on the host's network. | + +More information can be found in the network driver specific pages, including +their configuration options and details about their functionality. + +Native Windows containers have a different set of drivers, see +[Windows container network drivers](https://learn.microsoft.com/en-us/virtualization/windowscontainers/container-networking/network-drivers-topologies). + +### Connecting to multiple networks + +Connecting a container to a network can be compared to connecting an Ethernet +cable to a physical host. Just as a host can be connected to multiple Ethernet +networks, a container can be connected to multiple Docker networks. + +For example, a frontend container may be connected to a bridge network +with external access, and a +[`--internal`](/reference/cli/docker/network/create/#internal) network +to communicate with containers running backend services that do not need +external network access. + +A container may also be connected to different types of network. For example, +an `ipvlan` network to provide internet access, and a `bridge` network for +access to local services. + +Containers can also share networking stacks, see [Container networks](#container-networks). + +When sending packets, if the destination is an address in a directly connected +network, packets are sent to that network. Otherwise, packets are sent to +a default gateway for routing to their destination. In the example above, +the `ipvlan` network's gateway must be the default gateway. + +The default gateway is selected by Docker, and may change whenever a +container's network connections change. +To make Docker choose a specific default gateway when creating the container +or connecting a new network, set a gateway priority. See option `gw-priority` +for the [`docker run`](/reference/cli/docker/container/run/) and +[`docker network connect`](/reference/cli/docker/network/connect/) commands. + +The default `gw-priority` is `0` and the gateway in the network with the +highest priority is the default gateway. So, when a network should always +be the default gateway, it is enough to set its `gw-priority` to `1`. + +```console +$ docker run --network name=gwnet,gw-priority=1 --network anet1 --name myctr myimage +$ docker network connect anet2 myctr +``` + +## Published ports + +When you create or run a container using `docker create` or `docker run`, all +ports of containers on bridge networks are accessible from the Docker host and +other containers connected to the same network. Ports are not accessible from +outside the host or, with the default configuration, from containers in other +networks. + +Use the `--publish` or `-p` flag to make a port available outside the host, +and to containers in other bridge networks. + +For more information about port mapping, including how to disable it and use +direct routing to containers, see +[port publishing](./port-publishing.md). + +## IP address and hostname + +When creating a network, IPv4 address allocation is enabled by default, it +can be disabled using `--ipv4=false`. IPv6 address allocation can be enabled +using `--ipv6`. + +```console +$ docker network create --ipv6 --ipv4=false v6net +``` + +By default, the container gets an IP address for every Docker network it attaches to. +A container receives an IP address out of the IP subnet of the network. +The Docker daemon performs dynamic subnetting and IP address allocation for containers. +Each network also has a default subnet mask and gateway. + +You can connect a running container to multiple networks, +either by passing the `--network` flag multiple times when creating the container, +or using the `docker network connect` command for already running containers. +In both cases, you can use the `--ip` or `--ip6` flags to specify the container's IP address on that particular network. + +In the same way, a container's hostname defaults to be the container's ID in Docker. +You can override the hostname using `--hostname`. +When connecting to an existing network using `docker network connect`, +you can use the `--alias` flag to specify an additional network alias for the container on that network. + +### Subnet allocation + +Docker networks can use either explicitly configured subnets or automatically allocated ones from default pools. + +#### Explicit subnet configuration + +You can specify exact subnets when creating a network: + +```console +$ docker network create --ipv6 --subnet 192.0.2.0/24 --subnet 2001:db8::/64 mynet +``` + +#### Automatic subnet allocation + +When no `--subnet` option is provided, Docker automatically selects a subnet from predefined "default address pools". +These pools can be configured in `/etc/docker/daemon.json`. Docker's built-in default is equivalent to: + +```json +{ + "default-address-pools": [ + {"base":"172.17.0.0/16","size":16}, + {"base":"172.18.0.0/16","size":16}, + {"base":"172.19.0.0/16","size":16}, + {"base":"172.20.0.0/14","size":16}, + {"base":"172.24.0.0/14","size":16}, + {"base":"172.28.0.0/14","size":16}, + {"base":"192.168.0.0/16","size":20} + ] +} +``` + +- `base`: The subnet that can be allocated from. +- `size`: The prefix length used for each allocated subnet. + +When an IPv6 subnet is required and there are no IPv6 addresses in `default-address-pools`, Docker allocates +subnets from a Unique Local Address (ULA) prefix. To use specific IPv6 subnets instead, add them to your +`default-address-pools`. See [Dynamic IPv6 subnet allocation](../daemon/ipv6.md#dynamic-ipv6-subnet-allocation) +for more information. + +Docker attempts to avoid address prefixes already in use on the host. However, you may need to customize +`default-address-pools` to prevent routing conflicts in some network environments. + +The default pools use large subnets, which limits the number of networks you can create. You can divide base +subnets into smaller pools to support more networks. + +For example, this configuration allows Docker to create 256 networks from `172.17.0.0/16`. +Docker will allocate subnets `172.17.0.0/24`, `172.17.1.0/24`, and so on, up to `172.17.255.0/24`: + +```json +{ + "default-address-pools": [ + {"base": "172.17.0.0/16", "size": 24} + ] +} +``` + +You can also request a subnet with a specific prefix length from the default pools by using unspecified +addresses in the `--subnet` option: + +```console +$ docker network create --ipv6 --subnet ::/56 --subnet 0.0.0.0/24 mynet +6686a6746b17228f5052528113ddad0e6d68e2e3905d648e336b33409f2d3b64 +$ docker network inspect mynet -f '{{json .IPAM.Config}}' | jq . +[ + { + "Subnet": "172.19.0.0/24", + "Gateway": "172.19.0.1" + }, + { + "Subnet": "fdd3:6f80:972c::/56", + "Gateway": "fdd3:6f80:972c::1" + } +] +``` + +> [!NOTE] +> +> Support for unspecified addresses in `--subnet` was introduced in Docker 29.0.0. +> If Docker is downgraded to an older version, networks created in this way will become unusable. +> They can be removed and re-created, or will function again if the daemon is restored to 29.0.0 or later. + +## DNS services + +Containers use the same DNS servers as the host by default, but you can +override this with `--dns`. + +By default, containers inherit the DNS settings as defined in the +`/etc/resolv.conf` configuration file. +Containers that attach to the default `bridge` network receive a copy of this file. +Containers that attach to a +[custom network](drivers/bridge.md#use-user-defined-bridge-networks) +use Docker's embedded DNS server. +The embedded DNS server forwards external DNS lookups to the DNS servers configured on the host. + +You can configure DNS resolution on a per-container basis, using flags for the +`docker run` or `docker create` command used to start the container. +The following table describes the available `docker run` flags related to DNS +configuration. + +| Flag | Description | +| -------------- |-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| +| `--dns` | The IP address of a DNS server.

This is useful +if you want to configure the gateway IP address for the bridge manually. For +instance if you add a physical interface to your bridge, and need it to have +the gateway address. + +With this configuration, north-south traffic (to and from the bridge network) +won't work unless you've manually configured the gateway address on the bridge, +or a device attached to it. + +This option can only be used with user-defined bridge networks. + +## Usage examples + +This section provides hands-on examples for working with bridge networks. + +### Use the default bridge network + +This example shows how the default `bridge` network works.

On `manager`, initialize the swarm. If the host has one network interface, + the `--advertise-addr` flag is optional: + + ```console + $ docker swarm init --advertise-addr= + ``` + + Save the join token displayed for use with workers. + +2. On `worker-1`, join the swarm: + + ```console + $ docker swarm join --token \ + --advertise-addr \ + :2377 + ``` + +3. On `worker-2`, join the swarm: + + ```console + $ docker swarm join --token \ + --advertise-addr \ + :2377 + ``` + +4. On `manager`, list all nodes: + + ```console + $ docker node ls + + ID HOSTNAME STATUS AVAILABILITY MANAGER STATUS + d68ace5iraw6whp7llvgjpu48 * ip-172-31-34-146 Ready Active Leader + nvp5rwavvb8lhdggo8fcf7plg ip-172-31-35-151 Ready Active + ouvx2l7qfcxisoyms8mtkgahw ip-172-31-36-89 Ready Active + ``` + + Filter by role if needed: + + ```console + $ docker node ls --filter role=manager + $ docker node ls --filter role=worker + ``` + +5. List Docker networks on all hosts. Each now has an overlay network called + `ingress` and a bridge network called `docker_gwbridge`: + + ```console + $ docker network ls + + NETWORK ID NAME DRIVER SCOPE + 495c570066be bridge bridge local + 961c6cae9945 docker_gwbridge bridge local + ff35ceda3643 host host local + trtnl4tqnc3n ingress overlay swarm + c8357deec9cb none null local + ``` + +The `docker_gwbridge` connects the `ingress` network to the Docker host's +network interface. If you create services without specifying a network, they +connect to `ingress`. It's recommended to use separate overlay networks for each +application or group of related applications. + +#### Create the services + +1. On `manager`, create a new overlay network: + + ```console + $ docker network create -d overlay nginx-net + ``` + + The overlay network is automatically created on worker nodes when they run + service tasks that need it. + +2. On `manager`, create a 5-replica Nginx service connected to `nginx-net`: + + > [!NOTE] + > Services can only be created on a manager. + + ```console + $ docker service create \ + --name my-nginx \ + --publish target=80,published=80 \ + --replicas=5 \ + --network nginx-net \ + nginx + ``` + + The default `ingress` publish mode means you can browse to port 80 on any + node and connect to one of the 5 service tasks, even if no tasks run on that + node. + +3. Monitor service creation progress: + + ```console + $ docker service ls + ``` + +4. Inspect the `nginx-net` network on all hosts. The `Containers` section lists + all service tasks connected to the overlay network from that host. + +5. From `manager`, inspect the service: + + ```console + $ docker service inspect my-nginx + ``` + + Notice the information about ports and endpoints. + +6. Create a second network and update the service to use it: + + ```console + $ docker network create -d overlay nginx-net-2 + $ docker service update \ + --network-add nginx-net-2 \ + --network-rm nginx-net \ + my-nginx + ``` + +7. Verify the update completed: + + ```console + $ docker service ls + ``` + + Inspect both networks to verify containers moved from `nginx-net` to + `nginx-net-2`. + + > [!NOTE] + > Overlay networks are automatically created on swarm worker nodes as needed, + > but aren't automatically removed. + +8. Clean up: + + ```console + $ docker service rm my-nginx + $ docker network rm nginx-net nginx-net-2 + ``` + +### Use a user-defined overlay network + +This example shows the recommended approach for production services using custom +overlay networks. + +#### Prerequisites + +This assumes the swarm is already set up and you're on a manager node. + +#### Steps + +1. Create a user-defined overlay network: + + ```console + $ docker network create -d overlay my-overlay + ``` + +2.

On `host1`, create an attachable overlay network: + + ```console + $ docker network create --driver=overlay --attachable test-net + uqsof8phj3ak0rq9k86zta6ht + ``` + + Note the returned network ID. + +3. On `host1`, start an interactive container that connects to `test-net`: + + ```console + $ docker run -it --name alpine1 --network test-net alpine + / # + ``` + +4.

If it enables IP Forwarding, it also sets the +default policy of the iptables `FORWARD` chain in the `filter` table to `DROP`. + +### Add iptables policies before Docker's rules + +Packets that get accepted or rejected by rules in these custom chains will not +be seen by user-defined rules appended to the `FORWARD` chain. So, to add +additional rules to filter these packets, use the `DOCKER-USER` chain. + +Rules appended to the `FORWARD` chain will be processed after Docker's rules. + +### Match the original IP and ports for requests + +When packets arrive to the `DOCKER-USER` chain, they have already passed through +a Destination Network Address Translation (DNAT) filter. That means that the +`iptables` flags you use can only match internal IP addresses and ports of +containers. + +If you want to match traffic based on the original IP and port in the network +request, you must use the +[`conntrack` iptables extension](https://ipset.netfilter.org/iptables-extensions.man.html#lbAO). +For example: + +```console +$ sudo iptables -I DOCKER-USER -p tcp -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT +$ sudo iptables -I DOCKER-USER -p tcp -m conntrack --ctorigdst 198.51.100.2 --ctorigdstport 80 -j ACCEPT +``` + +> [!IMPORTANT] +> +> Using the `conntrack` extension may result in degraded performance. + +### Allow forwarding between host interfaces + +If Docker has set the default policy of the `FORWARD` chain in the `filter` +table to `DROP`, a rule in `DOCKER-USER` can be used to allow forwarding +between host interfaces.

For example, the +following rule drops packets from all IP addresses except `192.0.2.2`: + +```console +$ iptables -I DOCKER-USER -i ext_if ! -s 192.0.2.2 -j DROP +``` + +You will need to change `ext_if` to correspond with your +host's actual external interface.

The following rule only allows access from the subnet `192.0.2.0/24`: + +```console +$ iptables -I DOCKER-USER -i ext_if ! -s 192.0.2.0/24 -j DROP +``` + +Finally, you can specify a range of IP addresses to accept using `--src-range` +(Remember to also add `-m iprange` when using `--src-range` or `--dst-range`): + +```console +$ iptables -I DOCKER-USER -m iprange -i ext_if ! --src-range 192.0.2.1-192.0.2.3 -j DROP +``` + +You can combine `-s` or `--src-range` with `-d` or `--dst-range` to control both +the source and destination. For example, if the Docker host has addresses +`2001:db8:1111::2` and `2001:db8:2222::2`, you can make rules specific to +`2001:db8:1111::2` and leave `2001:db8:2222::2` open. + +You may need to allow responses from servers outside the permitted external address +ranges. For example, containers may send DNS or HTTP requests to hosts that are +not allowed to access the container's services. The following rule accepts any +incoming or outgoing packet belonging to a flow that has already been accepted +by other rules. It must be placed before `DROP` rules that restrict access from +external address ranges. + +```console +$ iptables -I DOCKER-USER -m state --state RELATED,ESTABLISHED -j ACCEPT +``` + +For more information about iptables configuration and advanced usage, +refer to the [Netfilter.org HOWTO](https://www.netfilter.org/documentation/HOWTO/NAT-HOWTO.html). diff --git a/content/manuals/engine/network/firewall-nftables.md b/content/manuals/engine/network/firewall-nftables.md new file mode 100644 index 000000000000..f868e6c95e75 --- /dev/null +++ b/content/manuals/engine/network/firewall-nftables.md @@ -0,0 +1,275 @@ +--- +title: Docker with nftables +weight: 10 +description: How Docker works with nftables +keywords: network, nftables, firewall +--- + +> [!WARNING] +> +> Support for nftables introduced in Docker 29.0.0 is experimental, configuration +> options, behavior and implementation may all change in future releases. +> The rules for overlay networks have not yet been migrated from iptables. +> Therefore, nftables cannot be enabled when the Docker daemon is running in +> Swarm mode. + +To use nftables instead of iptables, use Docker Engine option +`--firewall-backend=nftables` on its command line, or `"firewall-backend": "nftables"` +in its configuration file.

See [FORWARD policy in iptables](#forward-policy-in-iptables). + +### IP forwarding + +IP forwarding on the Docker host enables Docker functionality including port +publishing, communication between bridge networks, and direct routing from +outside the host to containers in bridge networks. + +When running with iptables, depending on network and daemon configuration, +Docker may enable IPv4 and IPv6 forwarding on the host. + +With its nftables firewall backend enabled, Docker will not enable IP forwarding +itself. It will report an error if forwarding is needed, but not already enabled. +To disable Docker's check for IP forwarding, letting it start and create networks +when it determines that forwarding is disabled, use Daemon option `--ip-forward=false`, +or `"ip-forward": false` in its configuration file. + +> [!WARNING] +> +> When enabling IP forwarding, make sure you have firewall rules to block +> unwanted forwarding between non-Docker interfaces. + +> [!NOTE] +> +> If you stop Docker to migrate to nftables, Docker may have already enabled +> IP forwarding on your system. After a reboot, if no other service re-enables +> forwarding, Docker will fail to start. + +If Docker is in a VM that has a single network interface and no other +software running, there is probably no unwanted forwarding to block. +But, on a physical host with multiple network interfaces, forwarding +between those interfaces should probably be blocked with nftables rules +unless the host is acting as a router. + +To enable IP forwarding on the host, set the following sysctls: + +- `net.ipv4.ip_forward=1` +- `net.ipv6.conf.all.forwarding=1` + +If your host uses `systemd`, you may be able to use `systemd-sysctl`. For +example, by editing `/etc/sysctl.d/99-sysctl.conf`. + +If the host is running `firewalld`, you may be able to use it to block +unwanted forwarding. Docker's bridges are in a firewalld zone called +`docker`, it creates a forwarding policy called `docker-forwarding` that +accepts forwarding from `ANY` zone to the `docker` zone. + +For example, to use nftables to block forwarding between interfaces `eth0` +and `eth1`, you could use: + +```console +table inet no-ext-forwarding { + chain no-ext-forwarding { + type filter hook forward priority filter; policy accept; + iifname "eth0" oifname "eth1" drop + iifname "eth1" oifname "eth0" drop + } +} +``` + +### FORWARD policy in iptables + +An iptables chain with `FORWARD` policy `DROP` will drop packets that have +been accepted by Docker's nftables rules, because the packet will be processed +by the iptables chains as well as Docker's nftables chains. + +Some features, including port publishing, will not work unless the `DROP` +policy is removed, or additional iptables rules are added to the iptables +`FORWARD` chain to accept Docker-related traffic. + +When Docker is using iptables, and it enables IP forwarding on the host, +it sets the default policy of the iptables `FORWARD` chain to `DROP`. So, +if you stop Docker to migrate to nftables, it may have set a `DROP` that +you need to remove. It will be removed anyway on reboot. + +To keep using rules in `DOCKER-USER` that rely on the chain having policy +`DROP`, you must add explicit `ACCEPT` rules for Docker related traffic. + +To check the current iptables `FORWARD` policy, use: + +```console +$ iptables -L FORWARD +Chain FORWARD (policy DROP) +target prot opt source destination +$ ip6tables -L FORWARD +Chain FORWARD (policy ACCEPT) +target prot opt source destination +``` + +To set the iptables policies to `ACCEPT` for IPv4 and IPv6: + +```console +$ iptables -P FORWARD ACCEPT +$ ip6tables -P FORWARD ACCEPT +``` + +### Migrating `DOCKER-USER` + +With firewall backend "iptables", rules added to the iptables `DOCKER-USER` +are processed before Docker's rules in the filter table's `FORWARD` chain. + +When starting the daemon with nftables after running with iptables, Docker +will not remove the jump from the `FORWARD` chain to `DOCKER-USER`. So, +rules created in `DOCKER-USER` will continue to run until the jump is +removed or the host is rebooted. + +When starting with nftables, the daemon will not add the jump. So, unless +there is an existing jump, rules in `DOCKER-USER` will be ignored. + +#### Migrating ACCEPT rules + +Some rules in the `DOCKER-USER` chain will continue to work. For example, if a +packet is dropped, it will be dropped before or after the nftables rules in +Docker's `filter-FORWARD` chain. But other rules, particularly `ACCEPT` rules +to override Docker's `DROP` rules, will not work. + +In nftables, an "accept" rule is not final. It terminates processing +for its base chain, but the accepted packet will still be processed by +other base chains, which may drop it. + +To override Docker's `drop` rule, you must use a firewall mark. Select a +mark not already in use on your host, and use Docker Engine option +`--bridge-accept-fwmark`. + +For example, `--bridge-accept-fwmark=1` tells the daemon to accept any +packet with an `fwmark` value of `1`. Optionally, you can supply a mask +to match specific bits in the mark, `--bridge-accept-fwmark=0x1/0x3`. + +Then, instead of accepting the packet in `DOCKER-USER`, add the firewall +mark you have chosen and Docker will not drop it. + +The firewall mark must be added before Docker's rules run. So if the mark +is added in a chain with type `filter` and hook `forward`, it must have +priority `filter - 1` or lower. + +#### Replacing `DOCKER-USER` with an nftables table + +Because nftables doesn't have pre-defined chains, to replace the `DOCKER-USER` +chain you can create your own table and add chains and rules to it. + +The `DOCKER-USER` chain has type `filter` and hook `forward`, so it can +only have rules in the filter forward chain. The base chains in your +table can have any `type` or `hook`. If your rules need to run before +Docker's rules, give the base chains a lower `priority` number than +Docker's chain. Or, a higher priority to make sure they run after Docker's +rules. + +Docker's base chains use the priority values defined at +[priority values](https://wiki.nftables.org/wiki-nftables/index.php/Netfilter_hooks#Priority_within_hook) + +#### Example: restricting external connections to containers + +By default, any remote host can connect to ports published to the Docker +host's external addresses. + +To allow only a specific IP or network to access the containers, create a +table with a base chain that has a drop rule. For example, the +following table drops packets from all IP addresses except `192.0.2.2`: + +```console +table ip my-table { + chain my-filter-forward { + type filter hook forward priority filter; policy accept; + iifname "ext_if" ip saddr != 192.0.2.2 counter drop + } +} +``` + +You will need to change `ext_if` to your host's external interface name. + +You could instead accept connections from a source subnet. The following +table only accepts access from the subnet `192.0.2.0/24`: + +```console +table ip my-table { + chain my-filter-forward { + type filter hook forward priority filter; policy accept; + iifname "ext_if" ip saddr != 192.0.2.0/24 counter drop + } +} +``` + +If you are running other services on the host that use IP forwarding +and need to be accessed by different external hosts, you will need more +specific filters. For example, to match the default prefix `br-` of +bridge devices belonging to Docker's user-defined bridge networks: + +```console +table ip my-table { + chain my-filter-forward { + type filter hook forward priority filter; policy accept; + iifname "ext_if" oifname "br-*" ip saddr != 192.0.2.0/24 counter drop + } +} +``` + +For more information about nftables configuration and advanced usage, +refer to the [nftables wiki](https://wiki.nftables.org/wiki-nftables/index.php/Main_Page). diff --git a/content/manuals/engine/network/links.md b/content/manuals/engine/network/links.md new file mode 100644 index 000000000000..acdc38fbc0c0 --- /dev/null +++ b/content/manuals/engine/network/links.md @@ -0,0 +1,411 @@ +--- +description: Learn how to connect Docker containers together. +keywords: Examples, Usage, user guide, links, linking, docker, documentation, examples, + names, name, container naming, port, map, network port, network +title: Legacy container links +aliases: +- /userguide/dockerlinks/ +- /engine/userguide/networking/default_network/dockerlinks/ +- /network/links/ +--- + +> [!WARNING] +> +> The `--link` flag is a legacy feature of Docker.

Here port 80 of the host is mapped to port 5000 of the +container: + +```console +$ docker run -d -p 80:5000 training/webapp python app.py +``` + +And you saw why this isn't such a great idea because it constrains you to +only one container on that specific port. + +Instead, you may specify a range of host ports to bind a container port to +that is different than the default *ephemeral port range*: + +```console +$ docker run -d -p 8000-9000:5000 training/webapp python app.py +``` + +This would bind port 5000 in the container to a randomly available port +between 8000 and 9000 on the host. + +There are also a few other ways you can configure the `-p` flag. By +default the `-p` flag binds the specified port to all interfaces on +the host machine. But you can also specify a binding to a specific +interface, for example only to the `localhost`. + +```console +$ docker run -d -p 127.0.0.1:80:5000 training/webapp python app.py +``` + +This would bind port 5000 inside the container to port 80 on the +`localhost` or `127.0.0.1` interface on the host machine. + +Or, to bind port 5000 of the container to a dynamic port but only on the +`localhost`, you could use: + +```console +$ docker run -d -p 127.0.0.1::5000 training/webapp python app.py +``` + +You can also bind UDP and SCTP (typically used by telecom protocols such as SIGTRAN, Diameter, and S1AP/X2AP) ports by adding a trailing `/udp` or `/sctp`. For example: + +```console +$ docker run -d -p 127.0.0.1:80:5000/udp training/webapp python app.py +``` + +You also learned about the useful `docker port` shortcut which showed us the +current port bindings. This is also useful for showing you specific port +configurations. For example, if you've bound the container port to the +`localhost` on the host machine, then the `docker port` output reflects that. + +```console +$ docker port nostalgic_morse 5000 + +127.0.0.1:49155 +``` + +> [!NOTE] +> +> The `-p` flag can be used multiple times to configure multiple ports. + +## Connect with the linking system + +> [!NOTE] +> +> This section covers the legacy link feature in the default `bridge` network. +> Refer to [differences between user-defined bridges and the default bridge](drivers/bridge.md#differences-between-user-defined-bridges-and-the-default-bridge) +> for more information on links in user-defined networks. + +Network port mappings are not the only way Docker containers can connect to one +another. Docker also has a linking system that allows you to link multiple +containers together and send connection information from one to another. When +containers are linked, information about a source container can be sent to a +recipient container. This allows the recipient to see selected data describing +aspects of the source container. + +### The importance of naming + +To establish links, Docker relies on the names of your containers. +You've already seen that each container you create has an automatically +created name; indeed you've become familiar with our old friend +`nostalgic_morse` during this guide. You can also name containers +yourself. This naming provides two useful functions: + +1. It can be useful to name containers that do specific functions in a way + that makes it easier for you to remember them, for example naming a + container containing a web application `web`. + +2. It provides Docker with a reference point that allows it to refer to other + containers, for example, you can specify to link the container `web` to container `db`. + +You can name your container by using the `--name` flag, for example: + +```console +$ docker run -d -P --name web training/webapp python app.py +``` + +This launches a new container and uses the `--name` flag to +name the container `web`. You can see the container's name using the +`docker ps` command. + +```console +$ docker ps -l + +CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES +aed84ee21bde training/webapp:latest python app.py 12 hours ago Up 2 seconds 0.0.0.0:49154->5000/tcp web +``` + +You can also use `docker inspect` to return the container's name. + + +> [!NOTE] +> +> Container names must be unique. That means you can only call +> one container `web`. If you want to re-use a container name you must delete +> the old container (with `docker container rm`) before you can create a new +> container with the same name. As an alternative you can use the `--rm` +> flag with the `docker run` command. This deletes the container +> immediately after it is stopped. + +## Communication across links + +Links allow containers to discover each other and securely transfer information +about one container to another container. When you set up a link, you create a +conduit between a source container and a recipient container. The recipient can +then access select data about the source. To create a link, you use the `--link` +flag. First, create a new container, this time one containing a database. + +```console +$ docker run -d --name db training/postgres +``` + +This creates a new container called `db` from the `training/postgres` +image, which contains a PostgreSQL database. + +Now, you need to delete the `web` container you created previously so you can replace it +with a linked one: + +```console +$ docker container rm -f web +``` + +Now, create a new `web` container and link it with your `db` container. + +```console +$ docker run -d -P --name web --link db:db training/webapp python app.py +``` + +This links the new `web` container with the `db` container you created +earlier. The `--link` flag takes the form: + + --link :alias + +Where `name` is the name of the container we're linking to and `alias` is an +alias for the link name. That alias is used shortly. +The `--link` flag also takes the form: + + --link + +In this case the alias matches the name. You could write the previous +example as: + +```console +$ docker run -d -P --name web --link db training/webapp python app.py +``` + +Next, inspect your linked containers with `docker inspect`: + + +```console +$ docker inspect -f "{{ .HostConfig.Links }}" web + +[/db:/web/db] +``` + + +You can see that the `web` container is now linked to the `db` container +`web/db`. Which allows it to access information about the `db` container. + +So what does linking the containers actually do? You've learned that a link allows a +source container to provide information about itself to a recipient container. In +our example, the recipient, `web`, can access information about the source `db`. To do +this, Docker creates a secure tunnel between the containers that doesn't need to +expose any ports externally on the container; when we started the +`db` container we did not use either the `-P` or `-p` flags. That's a big benefit of +linking: we don't need to expose the source container, here the PostgreSQL database, to +the network. + +Docker exposes connectivity information for the source container to the +recipient container in two ways: + +* Environment variables, +* Updating the `/etc/hosts` file. + +### Environment variables + +Docker creates several environment variables when you link containers. Docker +automatically creates environment variables in the target container based on +the `--link` parameters. It also exposes all environment variables +originating from Docker from the source container. These include variables from: + +* the `ENV` commands in the source container's Dockerfile +* the `-e`, `--env`, and `--env-file` options on the `docker run` +command when the source container is started + +These environment variables enable programmatic discovery from within the +target container of information related to the source container. + +> [!WARNING] +> +> It is important to understand that all environment variables originating +> from Docker within a container are made available to any container +> that links to it. This could have serious security implications if sensitive +> data is stored in them. + +Docker sets an `_NAME` environment variable for each target container +listed in the `--link` parameter. For example, if a new container called +`web` is linked to a database container called `db` via `--link db:webdb`, +then Docker creates a `WEBDB_NAME=/web/webdb` variable in the `web` container. + +Docker also defines a set of environment variables for each port exposed by the +source container. Each variable has a unique prefix in the form `_PORT__` + +The components in this prefix are: + +* the alias `` specified in the `--link` parameter (for example, `webdb`) +* the `` number exposed +* a `` which is either TCP or UDP + +Docker uses this prefix format to define three distinct environment variables: + +* The `prefix_ADDR` variable contains the IP Address from the URL, for +example `WEBDB_PORT_5432_TCP_ADDR=172.17.0.82`. +* The `prefix_PORT` variable contains just the port number from the URL of +example `WEBDB_PORT_5432_TCP_PORT=5432`. +* The `prefix_PROTO` variable contains just the protocol from the URL of +example `WEBDB_PORT_5432_TCP_PROTO=tcp`. + +If the container exposes multiple ports, an environment variable set is +defined for each one. This means, for example, if a container exposes 4 ports +that Docker creates 12 environment variables, 3 for each port. + +Additionally, Docker creates an environment variable called `_PORT`. +This variable contains the URL of the source container's first exposed port. +The 'first' port is defined as the exposed port with the lowest number. +For example, consider the `WEBDB_PORT=tcp://172.17.0.82:5432` variable. If +that port is used for both tcp and udp, then the tcp one is specified. + +Finally, Docker also exposes each Docker originated environment variable +from the source container as an environment variable in the target. For each +variable Docker creates an `_ENV_` variable in the target +container. The variable's value is set to the value Docker used when it +started the source container. + +Returning back to our database example, you can run the `env` +command to list the specified container's environment variables. + +```console +$ docker run --rm --name web2 --link db:db training/webapp env + +<...> +DB_NAME=/web2/db +DB_PORT=tcp://172.17.0.5:5432 +DB_PORT_5432_TCP=tcp://172.17.0.5:5432 +DB_PORT_5432_TCP_PROTO=tcp +DB_PORT_5432_TCP_PORT=5432 +DB_PORT_5432_TCP_ADDR=172.17.0.5 +<...> +``` + +You can see that Docker has created a series of environment variables with +useful information about the source `db` container. Each variable is prefixed +with +`DB_`, which is populated from the `alias` you specified above. If the `alias` +were `db1`, the variables would be prefixed with `DB1_`. You can use these +environment variables to configure your applications to connect to the database +on the `db` container. The connection is secure and private; only the +linked `web` container can communicate with the `db` container. + +### Important notes on Docker environment variables + +Unlike host entries in the [`/etc/hosts` file](#updating-the-etchosts-file), +IP addresses stored in the environment variables are not automatically updated +if the source container is restarted. We recommend using the host entries in +`/etc/hosts` to resolve the IP address of linked containers. + +These environment variables are only set for the first process in the +container. Some daemons, such as `sshd`, scrub them when spawning shells +for connection. + +### Updating the `/etc/hosts` file + +In addition to the environment variables, Docker adds a host entry for the +source container to the `/etc/hosts` file. Here's an entry for the `web` +container: + +```console +$ docker run -t -i --rm --link db:webdb training/webapp /bin/bash + +root@aed84ee21bde:/opt/webapp# cat /etc/hosts +172.17.0.7 aed84ee21bde +<...> +172.17.0.5 webdb 6e5cdeb2d300 db +``` + +You can see two relevant host entries. The first is an entry for the `web` +container that uses the Container ID as a host name. The second entry uses the +link alias to reference the IP address of the `db` container. In addition to +the alias you provide, the linked container's name, if unique from the alias +provided to the `--link` parameter, and the linked container's hostname are +also added to `/etc/hosts` for the linked container's IP address.

No routes are normally set up in the host's network for container +addresses that exist within a host. + +But, particularly with IPv6 you may prefer to avoid using NAT and instead +arrange for external routing to container addresses ("direct routing"). + +To access containers on a bridge network from outside the Docker host, +you must first set up routing to the bridge network via an address on the +Docker host. This can be achieved using static routes, Border Gateway Protocol (BGP), +or any other means appropriate for your network. For example, within +a local layer 2 network, remote hosts can set up static routes to a container +network via the Docker daemon host's address on the local network. + +### Direct routing to containers in bridge networks + +By default, remote hosts are not allowed direct access to container IP +addresses in Docker's Linux bridge networks. They can only access ports +published to host IP addresses. + +To allow direct access to any published port, on any container, in any +Linux bridge network, use daemon option `"allow-direct-routing": true` +in `/etc/docker/daemon.json` or the equivalent `--allow-direct-routing`. + +To allow direct routing from anywhere to containers in a specific bridge +network, see [Gateway modes](#gateway-modes). + +Or, to allow direct routing via specific host interfaces, to a specific +bridge network, use the following option when creating the network: +- `com.docker.network.bridge.trusted_host_interfaces` + +#### Example + +Create a network where published ports on container IP addresses can be +accessed directly from interfaces `vxlan.1` and `eth3`: + +```console +$ docker network create --subnet 192.0.2.0/24 --ip-range 192.0.2.0/29 -o com.docker.network.bridge.trusted_host_interfaces="vxlan.1:eth3" mynet +``` + +Run a container in that network, publishing its port 80 to port 8080 on +the host's loopback interface: + +```console +$ docker run -d --ip 192.0.2.100 -p 127.0.0.1:8080:80 nginx +``` + +The web server running on the container's port 80 can now be accessed +from the Docker host at `http://127.0.0.1:8080`, or directly at +`http://192.0.2.100:80`. If remote hosts on networks connected to +interfaces `vxlan.1` and `eth3` have a route to the `192.0.2.0/24` +network inside the Docker host, they can also access the web server +via `http://192.0.2.100:80`. + +## Gateway modes + +The bridge network driver has the following options: +- `com.docker.network.bridge.gateway_mode_ipv6` +- `com.docker.network.bridge.gateway_mode_ipv4` + +Each of these can be set to one of the gateway modes: +- `nat` +- `nat-unprotected` +- `routed` +- `isolated` + +The default is `nat`, NAT and masquerading rules are set up for each +published container port. Packets leaving the host will use a host address. + +With mode `routed`, no NAT or masquerading rules are set up, but firewall +rules are still set up so that only published container ports are accessible. +Outgoing packets from the container will use the container's address, +not a host address. + +To access a published port in a `routed` network, remote hosts must have +a route to the container network via an external address on the Docker +host ("direct routing"). Hosts on the local layer-2 network can set up +direct routing without needing any additional network configuration. +Hosts outside the local network can only use direct routing to the +container if the network's routers are configured to enable it. + +In a `nat` mode network, publishing a port to an address on the loopback +interface means remote hosts cannot access it. Other published container +ports in `routed` and `nat` networks are always accessible from remote +hosts using direct routing, unless the Docker host's firewall has additional +restrictions. + +> [!NOTE] +> +> When a port is published to a specific host address in `nat` mode, if +> IP forwarding is enabled on the Docker host, the published port can be +> accessed via other host interfaces using direct routing to the host +> address. +> +> For example, a Docker host with IP forwarding enabled has two NICs with +> addresses `192.168.100.10/24` and `10.0.0.10/24`. +> When a port is published to `192.168.100.10`, a host in the `10.0.0.0/24` +> subnet can access that port by routing to `192.168.100.10` via `10.0.0.10`. + +In `nat-unprotected` mode, unpublished container ports are also +accessible using direct routing, no port filtering rules are set up. +This mode is included for compatibility with legacy default behaviour. + +The gateway mode also affects communication between containers that +are connected to different Docker networks on the same host. +- In `nat` and `nat-unprotected` modes, containers in other bridge + networks can only access published ports via the host addresses they + are published to. Direct routing from other networks is not allowed. +- In `routed` mode containers in other networks can use direct + routing to access ports, without going via a host address. + +In `routed` mode, a host port in a `-p` or `--publish` port mapping is +not used, and the host address is only used to decide whether to apply +the mapping to IPv4 or IPv6. So, when a mapping only applies to `routed` +mode, only addresses `0.0.0.0` or `::` should be used, and a host port +should not be given. If a specific address or port is given, it will +have no effect on the published port and a warning message will be +logged. + +Mode `isolated` can only be used when the network is also created with +CLI flag `--internal`, or equivalent. An address is normally assigned to the +bridge device in an `internal` network. So, processes on the Docker host can +access the network, and containers in the network can access host services +listening on that bridge address (including services listening on "any" host +address, `0.0.0.0` or `::`). No address is assigned to the bridge when the +network is created with gateway mode `isolated`. + +### Example + +Create a network suitable for direct routing for IPv6, with NAT enabled +for IPv4: +```console +$ docker network create --ipv6 --subnet 2001:db8::/64 -o com.docker.network.bridge.gateway_mode_ipv6=routed mynet +``` + +Create a container with a published port: +```console +$ docker run --network=mynet -p 8080:80 myimage +``` + +Then: +- Only container port 80 will be open, for IPv4 and IPv6. +- For IPv6, using `routed` mode, port 80 will be open on the container's IP + address. Port 8080 will not be opened on the host's IP addresses, and + outgoing packets will use the container's IP address. +- For IPv4, using the default `nat` mode, the container's port 80 will be + accessible via port 8080 on the host's IP addresses, as well as directly + from within the Docker host. But, container port 80 cannot be accessed + directly from outside the host. + Connections originating from the container will masquerade, using the + host's IP address. + +In `docker inspect`, this port mapping will be shown as follows. Note that +there is no `HostPort` for IPv6, because it is using `routed` mode: +```console +$ docker container inspect --format "{{json .NetworkSettings.Ports}}" +{"80/tcp":[{"HostIp":"0.0.0.0","HostPort":"8080"},{"HostIp":"::","HostPort":""}]} +``` + +Alternatively, to make the mapping IPv6-only, disabling IPv4 access to the +container's port 80, use the unspecified IPv6 address `[::]` and do not +include a host port number: +```console +$ docker run --network mynet -p '[::]::80' +``` + +## Setting the default bind address for containers + +By default, when a container's ports are mapped without any specific host +address, the Docker daemon publishes ports to all host addresses +(`0.0.0.0` and `[::]`). + +For example, the following command publishes port 8080 to all network +interfaces on the host, on both IPv4 and IPv6 addresses, potentially +making them available to the outside world. + +```console +docker run -p 8080:80 nginx +``` + +You can change the default binding address for published container ports so that +they're only accessible to the Docker host by default. To do that, you can +configure the daemon to use the loopback address (`127.0.0.1`) instead. + +> [!WARNING] +> +> In releases older than 28.0.0, hosts within the same L2 segment (for example, +> hosts connected to the same network switch) can reach ports published to +> localhost. For more information, see +> [moby/moby#45610](https://github.com/moby/moby/issues/45610) + +To configure this setting for user-defined bridge networks, use +the `com.docker.network.bridge.host_binding_ipv4` +[driver option](./drivers/bridge.md#default-host-binding-address) when you +create the network. Despite the option name, it is possible to specify an +IPv6 address. + +```console +$ docker network create mybridge \ + -o "com.docker.network.bridge.host_binding_ipv4=127.0.0.1" +``` + +Or, to set the default binding address for containers in all user-defined +bridge networks, use daemon configuration option `default-network-opts`. +For example: + +```json +{ + "default-network-opts": { + "bridge": { + "com.docker.network.bridge.host_binding_ipv4": "127.0.0.1" + } + } +} +``` + +> [!NOTE] +> +> Setting the default binding address to `::` means port bindings with no host +> address specified will work for any IPv6 address on the host. But, `0.0.0.0` +> means any IPv4 or IPv6 address. +> +> Changing the default bind address doesn't have any effect on Swarm services. +> Swarm services are always exposed on the `0.0.0.0` network interface. + +### Masquerade or SNAT for outgoing packets + +NAT is enabled by default for bridge networks, meaning outgoing packets +from containers are masqueraded. The source address of packets leaving +the Docker host is changed to an address on the host interface the packet +is sent on. + +Masquerading can be disabled for a user-defined bridge network by using +the `com.docker.network.bridge.enable_ip_masquerade` driver option when +creating the network. For example: +```console +$ docker network create mybridge \ + -o com.docker.network.bridge.enable_ip_masquerade=false ... +``` + +To use a specific source address for outgoing packets for a user-defined +network, instead of letting masquerading select an address, use options +`com.docker.network.host_ipv4` and `com.docker.network.host_ipv6` to +specify the Source NAT (SNAT) address to use. The +`com.docker.network.bridge.enable_ip_masquerade` option must +be `true`, the default, for these options to have any effect. + +### Default bridge + +To set the default binding for the default bridge network, configure the `"ip"` +key in the `daemon.json` configuration file: + +```json +{ + "ip": "127.0.0.1" +} +``` + +This changes the default binding address to `127.0.0.1` for published container +ports on the default bridge network. +Restart the daemon for this change to take effect. +Alternatively, you can use the `dockerd --ip` flag when starting the daemon. diff --git a/content/engine/release-notes/17.03.md b/content/manuals/engine/release-notes/17.03.md similarity index 92% rename from content/engine/release-notes/17.03.md rename to content/manuals/engine/release-notes/17.03.md index cd9cdc004c81..9c59a30ba57b 100644 --- a/content/engine/release-notes/17.03.md +++ b/content/manuals/engine/release-notes/17.03.md @@ -1,5 +1,6 @@ --- title: Docker Engine 17.03 release notes +linkTitle: Engine v17.03 toc_min: 1 toc_max: 2 --- @@ -70,13 +71,9 @@ toc_max: 2 ## 17.03.0-ce 2017-03-01 -**IMPORTANT**: Starting with this release, Docker is on a monthly release cycle and uses a -new YY.MM versioning scheme to reflect this.

[docker/cli#5178](https://github.com/docker/cli/pull/5178) + +#### Networking + +- Allow sysctls to be set per-interface during container creation and network connection. [moby/moby#47686](https://github.com/moby/moby/pull/47686) + * In a future release, this will be the only way to set per-interface sysctl options. + For example, on the command line in a `docker run` command,`--network mynet --sysctl net.ipv4.conf.eth0.log_martians=1` will be rejected. + Instead, you must use `--network name=mynet,driver-opt=com.docker.network.endpoint.sysctls=net.ipv4.conf.IFNAME.log_martians=1`. + +##### IPv6 + +- `ip6tables` is no longer experimental. You may remove the `experimental` configuration option and continue to use IPv6, if it is not required by any other features. +- `ip6tables` is now enabled for Linux bridge networks by default. [moby/moby#47747](https://github.com/moby/moby/pull/47747) + - This makes IPv4 and IPv6 behaviors consistent with each other, and reduces the risk that IPv6-enabled containers are inadvertently exposed to the network. + - There is no impact if you are running Docker Engine with `ip6tables` enabled (new default). + - If you are using an IPv6-enabled bridge network without `ip6tables`, this is likely a breaking change. Only published container ports (`-p` or `--publish`) are accessible from outside the Docker bridge network, and outgoing connections masquerade as the host. + - To restore the behavior of earlier releases, no `ip6tables` at all, set `"ip6tables": false` in `daemon.json`, or use the CLI option `--ip6tables=false`. Alternatively, leave `ip6tables` enabled, publish ports, and enable direct routing. + - With `ip6tables` enabled, if `ip6tables` is not functional on your host, Docker Engine will start but it will not be possible to create an IPv6-enabled network. + +##### IPv6 network configuration improvements + +- A Unique Local Address (ULA) base prefix is automatically added to `default-address-pools` if this parameter wasn't manually configured, or if it contains no IPv6 prefixes. [moby/moby#47853](https://github.com/moby/moby/pull/47853) + - Prior to this release, to create an IPv6-enabled network it was necessary to use the `--subnet` option to specify an IPv6 subnet, or add IPv6 ranges to `default-address-pools` in `daemon.json`. + - Starting in this release, when a bridge network is created with `--ipv6` and no IPv6 subnet is defined by those options, an IPv6 Unique Local Address (ULA) base prefix is used. + - The ULA prefix is derived from the Engine host ID such that it's unique across hosts and over time. +- IPv6 address pools of any size can now be added to `default-address-pools`. [moby/moby#47768](https://github.com/moby/moby/pull/47768) +- IPv6 can now be enabled by default on all custom bridge networks using `"default-network-opts": { "bridge": {"com.docker.network.enable_ipv6": "true"}}` in `daemon.json`, or `dockerd --default-network-opt=bridge=com.docker.network.enable_ipv6=true`on the command line. [moby/moby#47867](https://github.com/moby/moby/pull/47867) +- Direct routing for IPv6 networks, with `ip6tables` enabled. [moby/moby#47871](https://github.com/moby/moby/pull/47871) + - Added bridge driver option `com.docker.network.bridge.gateway_mode_ipv6=`. + - The default behavior, `nat`, is unchanged from previous releases running with `ip6tables` enabled. NAT and masquerading rules are set up for each published container port. + - When set to `routed`, no NAT or masquerading rules are configured for published ports. This enables direct IPv6 access to the container, if the host's network can route packets for the container's address to the host. Published ports will be opened in the container's firewall. + - When a port mapping only applies to `routed` mode, only addresses `0.0.0.0` or `::` are allowed and a host port must not be given. + - Note that published container ports, in `nat` or `routed` mode, are accessible from any remote address if routing is set up in the network, unless the Docker host's firewall has additional restrictions. For example: `docker network create --ipv6 -o com.docker.network.bridge.gateway_mode_ipv6=routed mynet`. + - The option `com.docker.network.bridge.gateway_mode_ipv4=` is also available, with the same behavior but for IPv4. +- If firewalld is running on the host, Docker creates policy `docker-forwarding` to allow forwarding from any zone to the `docker` zone. This makes it possible to configure a bridge network with a routable IPv6 address, and no NAT or masquerading. [moby/moby#47745](https://github.com/moby/moby/pull/47745) +- When a port is published with no host port specified, or a host port range is given, the same port will be allocated for IPv4 and IPv6. [moby/moby#47871](https://github.com/moby/moby/pull/47871) + - For example `-p 80` will result in the same ephemeral port being allocated for `0.0.0.0` and `::`, and `-p 8080-8083:80` will pick the same port from the range for both address families. + - Similarly, ports published to specific addresses will be allocated the same port. For example, `-p 127.0.0.1::80 -p '[::1]::80'`. + - If no port is available on all required addresses, container creation will fail. +- Environment variable `DOCKER_ALLOW_IPV6_ON_IPV4_INTERFACE`, introduced in release 26.1.1, no longer has any effect. [moby/moby#47963](https://github.com/moby/moby/pull/47963) + - If IPv6 could not be disabled on an interface because of a read-only `/proc/sys/net`, the environment variable allowed the container to start anyway. + - In this release, if IPv4 cannot be disabled for an interface, IPv6 can be explicitly enabled for the network simply by using `--ipv6` when creating it. Other workarounds are to configure the OS to disable IPv6 by default on new interfaces, mount `/proc/sys/net` read-write, or use a kernel with no IPv6 support. +- For IPv6-enabled bridge networks, do not attempt to replace the bridge's kernel-assigned link local address with `fe80::1`. [moby/moby#47787](https://github.com/moby/moby/pull/47787) + +#### Removed + +- Deprecate experimental GraphDriver plugins.

[moby/moby#48011](https://github.com/moby/moby/pull/48011) + +#### API + +- containerd image store: `POST /images/{name}/push` now supports a `platform` parameter (JSON encoded OCI Platform type) that allows selecting a specific platform-manifest from the multi-platform image. This is experimental and may change in future API versions. [moby/moby#47679](https://github.com/moby/moby/pull/47679) +- `POST /services/create` and `POST /services/{id}/update` now support `OomScoreAdj`.

[moby/moby#47866](https://github.com/moby/moby/pull/47866) +- `POST /containers/create` and `POST /services/create` now take `Options` as part of `HostConfig.Mounts.TmpfsOptions` allowing to set options for tmpfs mounts. [moby/moby#46809](https://github.com/moby/moby/pull/46809) +- The `Healthcheck.StartInterval` property is now correctly ignored when updating a Swarm service using API versions less than v1.44. [moby/moby#47991](https://github.com/moby/moby/pull/47991) +- `GET /events` now supports image `create` event that is emitted when a new image is built regardless if it was tagged or not. [moby/moby#47929](https://github.com/moby/moby/pull/47929) +- `GET /info` now includes a `Containerd` field containing information about the location of the containerd API socket and containerd namespaces used by the daemon to run containers and plugins. [moby/moby#47239](https://github.com/moby/moby/pull/47239) +- Deprecate non-standard (config) fields in image inspect output. The `Config` field returned by this endpoint (used for `docker image inspect`) returned additional fields that are not part of the image's configuration and not part of the [Docker Image Spec] and the [OCI Image Spec]. These fields are never set (and always return the default value for the type), but are not omitted in the response when left empty. As these fields were not intended to be part of the image configuration response, they are deprecated, and will be removed in the future API versions. +- Deprecate the daemon flag `--api-cors-header` and the corresponding `daemon.json` configuration option. These will be removed in the next major release. [moby/moby#45313](https://github.com/moby/moby/pull/45313) + +The following deprecated fields are currently included in the API response, but are not part of the underlying image's `Config`: [moby/moby#47941](https://github.com/moby/moby/pull/47941) + +- `Hostname` +- `Domainname` +- `AttachStdin` +- `AttachStdout` +- `AttachStderr` +- `Tty` +- `OpenStdin` +- `StdinOnce` +- `Image` +- `NetworkDisabled` (already omitted unless set) +- `MacAddress` (already omitted unless set) +- `StopTimeout` (already omitted unless set) + +#### Go SDK changes + +- Client API callback for the following functions now require a context parameter.

[moby/moby#48798](https://github.com/moby/moby/pull/48798) + * You can also specify `--mount type=image,image-subpath=[subpath],...` option to mount a specific path from the image. [docker/cli#5755](https://github.com/docker/cli/pull/5755) +- `docker images --tree` now shows metadata badges [docker/cli#5744](https://github.com/docker/cli/pull/5744) +- `docker load`, `docker save`, and `docker history` now support a `--platform` flag allowing you to choose a specific platform for single-platform operations on multi-platform images.

[docker/cli#5145](https://github.com/docker/cli/pull/5145) +- `docker buildx prune` now supports `reserved-space`, `max-used-space`, `min-free-space` and `keep-bytes` filters. [moby/moby#48720](https://github.com/moby/moby/pull/48720) +- Windows: Add support for running containerd as a child process of the daemon, instead of using a system-installed containerd. [moby/moby#47955](https://github.com/moby/moby/pull/47955) + + +### Networking + +- The `docker-proxy` binary has been updated, older versions will not work with the updated `dockerd`. [moby/moby#48132](https://github.com/moby/moby/pull/48132) + - Close a window in which the userland proxy (`docker-proxy`) could accept TCP connections, that would then fail after `iptables` NAT rules were set up. + - The executable `rootlesskit-docker-proxy` is no longer used, it has been removed from the build and distribution. +- DNS nameservers read from the host's `/etc/resolv.conf` are now always accessed from the host's network namespace. [moby/moby#48290](https://github.com/moby/moby/pull/48290) + - When the host's `/etc/resolv.conf` contains no nameservers and there are no `--dns` overrides, Google's DNS servers are no longer used, apart from by the default bridge network and in build containers. +- Container interfaces in bridge and macvlan networks now use randomly generated MAC addresses. [moby/moby#48808](https://github.com/moby/moby/pull/48808) + - Gratuitous ARP / Neighbour Advertisement messages will be sent when the interfaces are started so that, when IP addresses are reused, they're associated with the newly generated MAC address. + - IPv6 addresses in the default bridge network are now IPAM-assigned, rather than being derived from the MAC address. +- The deprecated OCI `prestart` hook is now only used by build containers. For other containers, network interfaces are added to the network namespace after task creation is complete, before the container task is started. [moby/moby#47406](https://github.com/moby/moby/pull/47406) +- Add a new `gw-priority` option to `docker run`, `docker container create`, and `docker network connect`. This option will be used by the Engine to determine which network provides the default gateway for a container. On `docker run`, this option is only available through the extended `--network` syntax. [docker/cli#5664](https://github.com/docker/cli/pull/5664) +- Add a new netlabel `com.docker.network.endpoint.ifname` to customize the interface name used when connecting a container to a network. It's supported by all built-in network drivers on Linux. [moby/moby#49155](https://github.com/moby/moby/pull/49155) + - When a container is created with multiple networks specified, there's no guarantee on the order networks will be connected to the container. So, if a custom interface name uses the same prefix as the auto-generated names, for example `eth`, the container might fail to start. + - The recommended practice is to use a different prefix, for example `en0`, or a numerical suffix high enough to never collide, for example `eth100`. + - This label can be specified on `docker network connect` via the `--driver-opt` flag, for example `docker network connect --driver-opt=com.docker.network.endpoint.ifname=foobar â€Ļ`. + - Or via the long-form `--network` flag on `docker run`, for example `docker run --network=name=bridge,driver-opt=com.docker.network.endpoint.ifname=foobar â€Ļ` +- If a custom network driver reports capability `GwAllocChecker` then, before a network is created, it will get a `GwAllocCheckerRequest` with the network's options. The custom driver may then reply that no gateway IP address should be allocated. [moby/moby#49372](https://github.com/moby/moby/pull/49372) + +#### Port publishing in bridge networks + +- `dockerd` now requires `ipset` support in the Linux kernel. [moby/moby#48596](https://github.com/moby/moby/pull/48596) + - The `iptables` and `ip6tables` rules used to implement port publishing and network isolation have been extensively modified. This enables some of the following functional changes, and is a first step in refactoring to enable native `nftables` support in a future release. [moby/moby#48815](https://github.com/moby/moby/issues/48815) + - If it becomes necessary to downgrade to an earlier version of the daemon, some manual cleanup of the new rules will be necessary. The simplest and surest approach is to reboot the host, or use `iptables -F` and `ip6tables -F` to flush all existing `iptables` rules from the `filter` table before starting the older version of the daemon. When that is not possible, run the following commands as root: + - `iptables -D FORWARD -m set --match-set docker-ext-bridges-v4 dst -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT; ip6tables -D FORWARD -m set --match-set docker-ext-bridges-v6 dst -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT` + - `iptables -D FORWARD -m set --match-set docker-ext-bridges-v4 dst -j DOCKER; ip6tables -D FORWARD -m set --match-set docker-ext-bridges-v6 dst -j DOCKER` + - If you were previously running with the iptables filter-FORWARD policy set to `ACCEPT` and need to restore access to unpublished ports, also delete per-bridge-network rules from the `DOCKER` chains. For example, `iptables -D DOCKER ! -i docker0 -o docker0 -j DROP`. +- Fix a security issue that was allowing remote hosts to connect directly to a container on its published ports. [moby/moby#49325](https://github.com/moby/moby/pull/49325) +- Fix a security issue that was allowing neighbor hosts to connect to ports mapped on a loopback address. [moby/moby#49325](https://github.com/moby/moby/pull/49325) +- Fix an issue that prevented port publishing to link-local addresses. [moby/moby#48570](https://github.com/moby/moby/pull/48570) +- UDP ports published by a container are now reliably accessible by containers on other networks, via the host's public IP address. [moby/moby#48571](https://github.com/moby/moby/pull/48571) +- Docker will now only set the `ip6tables` policy for the `FORWARD` chain in the `filter` table to `DROP` if it enables IP forwarding on the host itself (sysctls `net.ipv6.conf.all.forwarding` and `net.ipv6.conf.default.forwarding`). This is now aligned with existing IPv4 behaviour. [moby/moby#48594](https://github.com/moby/moby/pull/48594) + - If IPv6 forwarding is enabled on your host, but you were depending on Docker to set the ip6tables filter-FORWARD policy to `DROP`, you may need to update your host's configuration to make sure it is secure. +- Direct routed access to container ports that are not exposed using `p`/`-publish` is now blocked in the `DOCKER` iptables chain. [moby/moby#48724](https://github.com/moby/moby/pull/48724) + - If the default iptables filter-FORWARD policy was previously left at `ACCEPT` on your host, and direct routed access to a container's unpublished ports from a remote host is still required, options are: + - Publish the ports you need. + - Use the new `gateway_mode_ipv[46]=nat-unprotected`, described below. + - Container ports published to host addresses will continue to be accessible via those host addresses, using NAT or the userland proxy. + - Unpublished container ports continue to be directly accessible from the Docker host via the container's IP address. +- Networks created with `gateway_mode_ipv[46]=routed` are now accessible from other bridge networks running on the same Docker host, as well as from outside the host. [moby/moby#48596](https://github.com/moby/moby/pull/48596) +- Bridge driver options `com.docker.network.bridge.gateway_mode_ipv4` and `com.docker.network.bridge.gateway_mode_ipv6` now accept mode `nat-unprotected`. [moby/moby#48597](https://github.com/moby/moby/pull/48597) + - `nat-unprotected` is similar to the default `nat` mode, but no per port/protocol rules are set up. This means any port on a container can be accessed by direct-routing from a remote host. +- Bridge driver options `com.docker.network.bridge.gateway_mode_ipv4` and `com.docker.network.bridge.gateway_mode_ipv6` now accept mode `isolated`, when the network is also `internal`. [moby/moby#49262](https://github.com/moby/moby/pull/49262) + - An address is normally assigned to the bridge device in an `internal` network. So, processes on the Docker host can access the network, and containers in the network can access host services listening on that bridge address (including services listening on "any" host address, `0.0.0.0` or `::`). + - An `internal` bridge network created with gateway mode `isolated` does not have an address on the Docker host. +- When a port mapping includes a host IP address or port number that cannot be used because NAT from the host is disabled using `--gateway_mode_ipv[46]`, container creation will no longer fail. The unused fields may be needed if the gateway endpoint changes when networks are connected or disconnected. A message about the unused fields will be logged. [moby/moby#48575](https://github.com/moby/moby/pull/48575) +- Do not create iptables nat-POSTROUTING masquerade rules for a container's own published ports, when the userland proxy is enabled. [moby/moby#48854](https://github.com/moby/moby/pull/48854) + +#### IPv6 + +- Add `docker network create` option `--ipv4`. To disable IPv4 address assignment for a network, use `docker network create --ipv4=false [...]`. [docker/cli#5599](https://github.com/docker/cli/pull/5599) +- Daemon option `--ipv6` (`"ipv6": true` in `daemon.json`) can now be used without `fixed-cidr-v6`. [moby/moby#48319](https://github.com/moby/moby/pull/48319) +- IPAM now handles subnets bigger than "/64". [moby/moby#49223](https://github.com/moby/moby/pull/49223) +- Duplicate address detection (DAD) is now disabled for addresses assigned to the bridges belonging to bridge networks. [moby/moby#48609](https://github.com/moby/moby/pull/48609) +- Modifications to `host-gateway`, for compatibility with IPv6-only networks. [moby/moby#48807](https://github.com/moby/moby/pull/48807) + - When special value `host-gateway` is used in an `--add-host` option in place of an address, it's replaced by an address on the Docker host to make it possible to refer to the host by name. The address used belongs to the default bridge (normally `docker0`). Until now it's always been an IPv4 address, because all containers on bridge networks had IPv4 addresses. + - Now, if IPv6 is enabled on the default bridge network, `/etc/hosts` entries will be created for IPv4 and IPv6 addresses. So, a container that's only connected to IPv6-only networks can access the host by name. + - The `--host-gateway-ip` option overrides the address used to replace `host-gateway`. Two of these options are now allowed on the command line, for one IPv4 gateway and one IPv6. + - In the `daemon.json` file, to provide two addresses, use `"host-gateway-ips"`. For example, `"host-gateway-ips": ["192.0.2.1", "2001:db8::1111"]`. + + +### Bug fixes and enhancements + +- Add IPv6 loopback address as an insecure registry by default. [moby/moby#48540](https://github.com/moby/moby/pull/48540) +- Add support for Cobra-generated completion scripts for `dockerd`. [moby/moby#49339](https://github.com/moby/moby/pull/49339) +- Fix DNS queries failing when containers are launched via `systemd` auto-start on boot [moby/moby#48812](https://github.com/moby/moby/pull/48812) +- Fix Docker Swarm mode ignoring `volume.subpath` [docker/cli#5833](https://github.com/docker/cli/pull/5833) +- Fix `docker export` continuing the export after the operation is canceled. [moby/moby#49265](https://github.com/moby/moby/pull/49265) +- Fix `docker export` not releasing the container's writable layer after a failure. [moby/moby#48517](https://github.com/moby/moby/pull/48517) +- Fix `docker images --tree` unnecessary truncating long image names when multiple names are available [docker/cli#5757](https://github.com/docker/cli/pull/5757) +- Fix a bug where a container with a name matching another container's ID is not restored on daemon startup. [moby/moby#48669](https://github.com/moby/moby/pull/48669) +- Fix an issue preventing some IPv6 addresses shown by `docker ps` to be properly bracketed [docker/cli#5468](https://github.com/docker/cli/pull/5468) +- Fix bug preventing image pulls from being cancelled during `docker run`. [docker/cli#5645](https://github.com/docker/cli/pull/5645) +- Fix error-handling when running the daemon as a Windows service to prevent unclean exits. [moby/moby#48518](https://github.com/moby/moby/pull/48518) +- Fix issue causing output of `docker run` to be inconsistent when using `--attach stdout` or `--attach stderr` versus `stdin`. `docker run --attach stdin` now exits if the container exits. [docker/cli#5662](https://github.com/docker/cli/pull/5662) +- Fix rootless Docker setup with `subid` backed by NSS modules. [moby/moby#49036](https://github.com/moby/moby/pull/49036) +- Generated completion scripts from the CLI now show descriptions next to each command/flag suggestion. [docker/cli#5756](https://github.com/docker/cli/pull/5756) +- IPv6 addresses shown by `docker ps` in port bindings are now bracketed [docker/cli#5363](https://github.com/docker/cli/pull/5363) +- Implement the ports validation method for Compose [docker/cli#5524](https://github.com/docker/cli/pull/5524) +- Improve error-output for invalid flags on the command line. [docker/cli#5233](https://github.com/docker/cli/pull/5233) +- Improve errors when failing to start a container using anther container's network namespace. [moby/moby#49367](https://github.com/moby/moby/pull/49367) +- Improve handling of invalid API errors that could result in an empty error message being shown. [moby/moby#49373](https://github.com/moby/moby/pull/49373) +- Improve output and consistency for unknown (sub)commands and invalid arguments [docker/cli#5234](https://github.com/docker/cli/pull/5234) +- Improve validation of `exec-opts` in daemon configuration. [moby/moby#48979](https://github.com/moby/moby/pull/48979) +- Update the handling of the `--gpus=0` flag to be consistent with the NVIDIA Container Runtime. [moby/moby#48482](https://github.com/moby/moby/pull/48482) +- `client.ContainerCreate` now normalizes `CapAdd` and `CapDrop` fields in `HostConfig` to their canonical form. [moby/moby#48551](https://github.com/moby/moby/pull/48551) +- `docker image save` now produces stable timestamps. [moby/moby#48611](https://github.com/moby/moby/pull/48611) +- `docker inspect` now lets you inspect Swarm configs [docker/cli#5573](https://github.com/docker/cli/pull/5573) +- containerd image store: Add support for `Extracting` layer status in `docker pull`. [moby/moby#49064](https://github.com/moby/moby/pull/49064) +- containerd image store: Fix `commit`, `import`, and `build` not preserving a replaced image as a dangling image. [moby/moby#48316](https://github.com/moby/moby/pull/48316) +- containerd image store: Make `docker load --platform` return an error when the requested platform isn't loaded.

[docker/cli#5739](https://github.com/docker/cli/pull/5739) +- Add validation of network-diagnostic-port daemon configuration option. [moby/moby#49305](https://github.com/moby/moby/pull/49305) +- Unless explicitly configured, an IP address is no longer reserved for a gateway in cases where it is not required. Namely, “internal” bridge networks with option `com.docker.network.bridge.inhibit_ipv4`, `ipvlan` or `macvlan` networks with no parent interface, and L3 IPvlan modes. [moby/moby#49261](https://github.com/moby/moby/pull/49261) +- If a custom network driver reports capability `GwAllocChecker` then, before a network is created, it will get a `GwAllocCheckerRequest` with the network's options. The custom driver may then reply that no gateway IP address should be allocated. [moby/moby#49372](https://github.com/moby/moby/pull/49372) +- Fixed an issue that meant a container could not be attached to an L3 IPvlan at the same time as other network types. [moby/moby#49130](https://github.com/moby/moby/pull/49130) +- Remove the correct `/etc/hosts` entries when disconnecting a container from a network. [moby/moby#48857](https://github.com/moby/moby/pull/48857) +- Fix duplicate network disconnect events. [moby/moby#48800](https://github.com/moby/moby/pull/48800) +- Resolve issues related to changing `fixed-cidr` for `docker0`, and inferring configuration from a user-managed default bridge (`--bridge`). [moby/moby#48319](https://github.com/moby/moby/pull/48319) +- Remove feature flag `windows-dns-proxy`, introduced in release 26.1.0 to control forwarding to external DNS resolvers from Windows containers, to make `nslookup` work. It was enabled by default in release 27.0.0. [moby/moby#48738](https://github.com/moby/moby/pull/48738) +- Remove an `iptables` mangle rule for checksumming SCTP. The rule can be re-enabled by setting `DOCKER_IPTABLES_SCTP_CHECKSUM=1` in the daemon's environment. This override will be removed in a future release. [moby/moby#48149](https://github.com/moby/moby/pull/48149) +- Faster connection to bridge networks, in most cases.

When you start a container with +`docker run`, behind the scenes Docker creates a set of namespaces and control +groups for the container. + +Namespaces provide the first and most straightforward form of +isolation. Processes running within a container cannot see, and even +less affect, processes running in another container, or in the host +system. + +Each container also gets its own network stack, meaning that a +container doesn't get privileged access to the sockets or interfaces +of another container. Of course, if the host system is setup +accordingly, containers can interact with each other through their +respective network interfaces — just like they can interact with +external hosts. When you specify public ports for your containers or use +[links](/manuals/engine/network/links.md) +then IP traffic is allowed between containers. They can ping each other, +send/receive UDP packets, and establish TCP connections, but that can be +restricted if necessary. From a network architecture point of view, all +containers on a given Docker host are sitting on bridge interfaces. This +means that they are just like physical machines connected through a +common Ethernet switch; no more, no less. + +How mature is the code providing kernel namespaces and private +networking? Kernel namespaces were introduced [between kernel version +2.6.15 and +2.6.26](https://man7.org/linux/man-pages/man7/namespaces.7.html). +This means that since July 2008 (date of the 2.6.26 release +), namespace code has been exercised and scrutinized on a large +number of production systems. And there is more: the design and +inspiration for the namespaces code are even older. Namespaces are +actually an effort to reimplement the features of [OpenVZ]( +https://en.wikipedia.org/wiki/OpenVZ) in such a way that they could be +merged within the mainstream kernel. And OpenVZ was initially released +in 2005, so both the design and the implementation are pretty mature. + +## Control groups + +Control Groups are another key component of Linux containers. They +implement resource accounting and limiting. They provide many +useful metrics, but they also help ensure that each container gets +its fair share of memory, CPU, disk I/O; and, more importantly, that a +single container cannot bring the system down by exhausting one of those +resources. + +So while they do not play a role in preventing one container from +accessing or affecting the data and processes of another container, they +are essential to fend off some denial-of-service attacks. They are +particularly important on multi-tenant platforms, like public and +private PaaS, to guarantee a consistent uptime (and performance) even +when some applications start to misbehave. + +Control Groups have been around for a while as well: the code was +started in 2006, and initially merged in kernel 2.6.24. + +## Docker daemon attack surface + +Running containers (and applications) with Docker implies running the +Docker daemon. This daemon requires `root` privileges unless you opt-in +to [Rootless mode](rootless.md), and you should therefore be aware of +some important details. + +First of all, only trusted users should be allowed to control your +Docker daemon. This is a direct consequence of some powerful Docker +features. Specifically, Docker allows you to share a directory between +the Docker host and a guest container; and it allows you to do so +without limiting the access rights of the container. This means that you +can start a container where the `/host` directory is the `/` directory +on your host; and the container can alter your host filesystem +without any restriction. This is similar to how virtualization systems +allow filesystem resource sharing. Nothing prevents you from sharing your +root filesystem (or even your root block device) with a virtual machine. + +This has a strong security implication: for example, if you instrument Docker +from a web server to provision containers through an API, you should be +even more careful than usual with parameter checking, to make sure that +a malicious user cannot pass crafted parameters causing Docker to create +arbitrary containers. + +For this reason, the REST API endpoint (used by the Docker CLI to +communicate with the Docker daemon) changed in Docker 0.5.2, and now +uses a Unix socket instead of a TCP socket bound on 127.0.0.1 (the +latter being prone to cross-site request forgery attacks if you happen to run +Docker directly on your local machine, outside of a VM). You can then +use traditional Unix permission checks to limit access to the control +socket. + +You can also expose the REST API over HTTP if you explicitly decide to do so. +However, if you do that, be aware of the above mentioned security implications. +Note that even if you have a firewall to limit accesses to the REST API +endpoint from other hosts in the network, the endpoint can be still accessible +from containers, and it can easily result in the privilege escalation. +Therefore it is *mandatory* to secure API endpoints with +[HTTPS and certificates](protect-access.md). +Exposing the daemon API over HTTP without TLS is not permitted, +and such a configuration causes the daemon to fail early on startup, see +[Unauthenticated TCP connections](../deprecated.md#unauthenticated-tcp-connections). +It is also recommended to ensure that it is reachable only from a trusted +network or VPN. + +You can also use `DOCKER_HOST=ssh://USER@HOST` or `ssh -L /path/to/docker.sock:/var/run/docker.sock` +instead if you prefer SSH over TLS. + +The daemon is also potentially vulnerable to other inputs, such as image +loading from either disk with `docker load`, or from the network with +`docker pull`. As of Docker 1.3.2, images are now extracted in a chrooted +subprocess on Linux/Unix platforms, being the first-step in a wider effort +toward privilege separation. As of Docker 1.10.0, all images are stored and +accessed by the cryptographic checksums of their contents, limiting the +possibility of an attacker causing a collision with an existing image. + +Finally, if you run Docker on a server, it is recommended to run +exclusively Docker on the server, and move all other services within +containers controlled by Docker. Of course, it is fine to keep your +favorite admin tools (probably at least an SSH server), as well as +existing monitoring/supervision processes, such as NRPE and collectd. + +## Linux kernel capabilities + +By default, Docker starts containers with a restricted set of +capabilities. What does that mean? + +Capabilities turn the binary "root/non-root" dichotomy into a +fine-grained access control system. Processes (like web servers) that +just need to bind on a port below 1024 do not need to run as root: they +can just be granted the `net_bind_service` capability instead. And there +are many other capabilities, for almost all the specific areas where root +privileges are usually needed. This means a lot for container security. + +Typical servers run several processes as `root`, including the SSH daemon, +`cron` daemon, logging daemons, kernel modules, network configuration tools, +and more. A container is different, because almost all of those tasks are +handled by the infrastructure around the container: + + - SSH access are typically managed by a single server running on + the Docker host + - `cron`, when necessary, should run as a user + process, dedicated and tailored for the app that needs its + scheduling service, rather than as a platform-wide facility + - Log management is also typically handed to Docker, or to + third-party services like Loggly or Splunk + - Hardware management is irrelevant, meaning that you never need to + run `udevd` or equivalent daemons within + containers + - Network management happens outside of the containers, enforcing + separation of concerns as much as possible, meaning that a container + should never need to perform `ifconfig`, + `route`, or ip commands (except when a container + is specifically engineered to behave like a router or firewall, of + course) + +This means that in most cases, containers do not need "real" root +privileges at all* And therefore, containers can run with a reduced +capability set; meaning that "root" within a container has much less +privileges than the real "root". For instance, it is possible to: + + - Deny all "mount" operations + - Deny access to raw sockets (to prevent packet spoofing) + - Deny access to some filesystem operations, like creating new device + nodes, changing the owner of files, or altering attributes (including + the immutable flag) + - Deny module loading + +This means that even if an intruder manages to escalate to root within a +container, it is much harder to do serious damage, or to escalate +to the host. + +This doesn't affect regular web apps, but reduces the vectors of attack by +malicious users considerably. By default Docker +drops all capabilities except [those +needed](https://github.com/moby/moby/blob/master/daemon/pkg/oci/caps/defaults.go#L6-L19), +an allowlist instead of a denylist approach. You can see a full list of +available capabilities in [Linux +manpages](https://man7.org/linux/man-pages/man7/capabilities.7.html). + +One primary risk with running Docker containers is that the default set +of capabilities and mounts given to a container may provide incomplete +isolation, either independently, or when used in combination with +kernel vulnerabilities. + +Docker supports the addition and removal of capabilities, allowing use +of a non-default profile. This may make Docker more secure through +capability removal, or less secure through the addition of capabilities. +The best practice for users would be to remove all capabilities except +those explicitly required for their processes. + +## Docker Content Trust signature verification + +Docker Engine can be configured to only run signed images. The Docker Content +Trust signature verification feature is built directly into the `dockerd` binary. +This is configured in the Dockerd configuration file. + +To enable this feature, trustpinning can be configured in `daemon.json`, whereby +only repositories signed with a user-specified root key can be pulled and run. + +This feature provides more insight to administrators than previously available with +the CLI for enforcing and performing image signature verification. + +For more information on configuring Docker Content Trust Signature Verification, go to +[Content trust in Docker](trust/_index.md). + +## Other kernel security features + +Capabilities are just one of the many security features provided by +modern Linux kernels. It is also possible to leverage existing, +well-known systems like TOMOYO, AppArmor, SELinux, GRSEC, etc. with +Docker. + +While Docker currently only enables capabilities, it doesn't interfere +with the other systems. This means that there are many different ways to +harden a Docker host. Here are a few examples. + + - You can run a kernel with GRSEC and PAX. This adds many safety + checks, both at compile-time and run-time; it also defeats many + exploits, thanks to techniques like address randomization. It doesn't + require Docker-specific configuration, since those security features + apply system-wide, independent of containers. + - If your distribution comes with security model templates for + Docker containers, you can use them out of the box. For instance, we + ship a template that works with AppArmor and Red Hat comes with SELinux + policies for Docker. These templates provide an extra safety net (even + though it overlaps greatly with capabilities). + - You can define your own policies using your favorite access control + mechanism. + +Just as you can use third-party tools to augment Docker containers, including +special network topologies or shared filesystems, tools exist to harden Docker +containers without the need to modify Docker itself. + +As of Docker 1.10 User Namespaces are supported directly by the docker +daemon. This feature allows for the root user in a container to be mapped +to a non uid-0 user outside the container, which can help to mitigate the +risks of container breakout. This facility is available but not enabled +by default. + +Refer to the [daemon command](/reference/cli/dockerd.md#daemon-user-namespace-options) +in the command line reference for more information on this feature. +Additional information on the implementation of User Namespaces in Docker +can be found in +[this blog post](https://integratedcode.us/2015/10/13/user-namespaces-have-arrived-in-docker/). + +## Conclusions + +Docker containers are, by default, quite secure; especially if you +run your processes as non-privileged users inside the container. + +You can add an extra layer of safety by enabling AppArmor, SELinux, +GRSEC, or another appropriate hardening system. + +If you think of ways to make docker more secure, we welcome feature requests, +pull requests, or comments on the Docker community forums. + +## Related information + +* [Use trusted images](trust/_index.md) +* [Seccomp security profiles for Docker](seccomp.md) +* [AppArmor security profiles for Docker](apparmor.md) +* [On the Security of Containers (2014)](https://medium.com/@ewindisch/on-the-security-of-containers-2c60ffe25a9e) +* [Docker swarm mode overlay network security model](/manuals/engine/network/drivers/overlay.md) diff --git a/content/engine/security/antivirus.md b/content/manuals/engine/security/antivirus.md similarity index 94% rename from content/engine/security/antivirus.md rename to content/manuals/engine/security/antivirus.md index 37bf53282b89..326103fb7812 100644 --- a/content/engine/security/antivirus.md +++ b/content/manuals/engine/security/antivirus.md @@ -13,4 +13,4 @@ antivirus's exclusion list.

These signatures allow +client-side or runtime verification of the integrity and publisher of specific +image tags. + +Through DCT, image publishers can sign their images and image consumers can +ensure that the images they pull are signed. Publishers could be individuals +or organizations manually signing their content or automated software supply +chains signing content as part of their release process. + +> [!NOTE] +> +> Docker is retiring DCT for Docker Official Images +> (DOI). You should start planning to transition to a different image signing +> and verification solution (like [Sigstore](https://www.sigstore.dev/) or +> [Notation](https://github.com/notaryproject/notation#readme)). Timelines for the +> complete deprecation of DCT are being finalized and will be published soon. +> +> For more information, see [Retiring Docker Content Trust](https://www.docker.com/blog/retiring-docker-content-trust/). + +### Image tags and DCT + +An individual image record has the following identifier: + +```text +[REGISTRY_HOST[:REGISTRY_PORT]/]REPOSITORY[:TAG] +``` + +A particular image `REPOSITORY` can have multiple tags. For example, `latest` and + `3.1.2` are both tags on the `mongo` image. An image publisher can build an image + and tag combination many times changing the image with each build. + +DCT is associated with the `TAG` portion of an image. Each image repository has +a set of keys that image publishers use to sign an image tag. Image publishers +have discretion on which tags they sign. + +An image repository can contain an image with one tag that is signed and another +tag that is not. For example, consider [the Mongo image +repository](https://hub.docker.com/_/mongo/tags/). The `latest` +tag could be unsigned while the `3.1.6` tag could be signed. It is the +responsibility of the image publisher to decide if an image tag is signed or +not. In this representation, some image tags are signed, others are not: + +![Signed tags](images/tag_signing.png) + +Publishers can choose to sign a specific tag or not. As a result, the content of +an unsigned tag and that of a signed tag with the same name may not match. For +example, a publisher can push a tagged image `someimage:latest` and sign it. +Later, the same publisher can push an unsigned `someimage:latest` image. This second +push replaces the last unsigned tag `latest` but does not affect the signed `latest` version. +The ability to choose which tags they can sign, allows publishers to iterate over +the unsigned version of an image before officially signing it. + +Image consumers can enable DCT to ensure that images they use were signed. If a +consumer enables DCT, they can only pull, run, or build with trusted images. +Enabling DCT is a bit like applying a "filter" to your registry. Consumers "see" +only signed image tags and the less desirable, unsigned image tags are +"invisible" to them. + +![Trust view](images/trust_view.png) + +To the consumer who has not enabled DCT, nothing about how they work with Docker +images changes. Every image is visible regardless of whether it is signed or +not. + +### Docker Content Trust Keys + +Trust for an image tag is managed through the use of signing keys. A key set is +created when an operation using DCT is first invoked.

For more information, see the [Notary GitHub repository](https://github.com/theupdateframework/notary). + +A prerequisite for signing an image is a Docker Registry with a Notary server (such as Docker Hub) attached. +Refer to [Deploying Notary](/engine/security/trust/deploying_notary/) for instructions. + +> [!NOTE] +> +> Docker is retiring DCT for Docker Official Images +> (DOI).

Timelines for the +> complete deprecation of DCT are being finalized and will be published soon. +> +> For more information, see [Retiring Docker Content Trust](https://www.docker.com/blog/retiring-docker-content-trust/). + + +To sign a Docker Image you will need a delegation key pair. These keys +can be generated locally using `$ docker trust key generate` or generated +by a certificate authority. + +First we will add the delegation private key to the local Docker trust +repository. (By default this is stored in `~/.docker/trust/`). If you are +generating delegation keys with `$ docker trust key generate`, the private key +is automatically added to the local trust store. If you are importing a separate +key, you will need to use the +`$ docker trust key load` command. + +```console +$ docker trust key generate jeff +Generating key for jeff... +Enter passphrase for new jeff key with ID 9deed25: +Repeat passphrase for new jeff key with ID 9deed25: +Successfully generated and loaded private key. Corresponding public key available: /home/ubuntu/Documents/mytrustdir/jeff.pub +``` + +Or if you have an existing key: + +```console +$ docker trust key load key.pem --name jeff +Loading key from "key.pem"... +Enter passphrase for new jeff key with ID 8ae710e: +Repeat passphrase for new jeff key with ID 8ae710e: +Successfully imported key from key.pem +``` + +Next we will need to add the delegation public key to the Notary server; +this is specific to a particular image repository in Notary known as a Global +Unique Name (GUN). If this is the first time you are adding a delegation to that +repository, this command will also initiate the repository, using a local Notary +canonical root key.

This means that it can be difficult to get the data out of the +container if another process needs it. + +The writable layer is unique per container. You can't easily extract the data +from the writeable layer to the host, or to another container. + +## Storage mount options + +Docker supports the following types of storage mounts for storing data outside +of the writable layer of the container: + +- [Volume mounts](#volume-mounts) +- [Bind mounts](#bind-mounts) +- [tmpfs mounts](#tmpfs-mounts) +- [Named pipes](#named-pipes) + +No matter which type of mount you choose to use, the data looks the same from +within the container. It is exposed as either a directory or an individual file +in the container's filesystem. + +### Volume mounts + +Volumes are persistent storage mechanisms managed by the Docker daemon. They +retain data even after the containers using them are removed. Volume data is +stored on the filesystem on the host, but in order to interact with the data in +the volume, you must mount the volume to a container. Directly accessing or +interacting with the volume data is unsupported, undefined behavior, and may +result in the volume or its data breaking in unexpected ways. + +Volumes are ideal for performance-critical data processing and long-term +storage needs. Since the storage location is managed on the daemon host, +volumes provide the same raw file performance as accessing the host filesystem +directly. + +### Bind mounts + +Bind mounts create a direct link between a host system path and a container, +allowing access to files or directories stored anywhere on the host. Since they +aren't isolated by Docker, both non-Docker processes on the host and container +processes can modify the mounted files simultaneously. + +Use bind mounts when you need to be able to access files from both the +container and the host. + +### tmpfs mounts + +A tmpfs mount stores files directly in the host machine's memory, ensuring the +data is not written to disk. This storage is ephemeral: the data is lost when +the container is stopped or restarted, or when the host is rebooted. tmpfs +mounts do not persist data either on the Docker host or within the container's +filesystem. + +These mounts are suitable for scenarios requiring temporary, in-memory storage, +such as caching intermediate data, handling sensitive information like +credentials, or reducing disk I/O.

This differs from the classic graph +drivers like overlay2. + +The containerd image store enables: + +- Building and storing multi-platform images locally. With classic storage + drivers, you need external builders for multi-platform images. +- Working with images that include attestations (provenance, SBOM). These use + image indices that the classic store doesn't support. +- Running Wasm containers. The containerd image store supports WebAssembly + workloads. +- Using advanced snapshotters. containerd supports pluggable snapshotters that + provide features like lazy-pulling of images (stargz) or peer-to-peer image + distribution (nydus, dragonfly). + +For most users, switching to the containerd image store is transparent. The +storage backend changes, but your workflows remain the same. + +## Disk space usage + +The containerd image store uses more disk space than the legacy storage +drivers for the same images. This is because containerd stores images in both +compressed and uncompressed formats, while the legacy drivers stored only the +uncompressed layers. + +When you pull an image, containerd keeps the compressed layers (as received +from the registry) and also extracts them to disk. This dual storage means +each layer occupies more space. The compressed format enables faster pulls and +pushes, but requires additional disk capacity. + +This difference is particularly noticeable with multiple images sharing the +same base layers. With legacy storage drivers, shared base layers were stored +once locally, and reused images that depended on them. With containerd, each +image stores its own compressed version of shared layers, even though the +uncompressed layers are still de-duplicated through snapshotters. The +compressed storage adds overhead proportional to the number of images using +those layers. + +If disk space is constrained, consider the following: + +- Regularly prune unused images with `docker image prune` +- Use `docker system df` to monitor disk usage +- [Configure the data directory](../daemon/_index.md#configure-the-data-directory-location) + to use a partition with adequate space + +## Enable containerd image store on Docker Engine + +If you're upgrading from an earlier Docker Engine version, you need to manually +enable the containerd image store. + +> [!IMPORTANT] +> Switching storage backends temporarily hides images and containers created +> with the other backend.

You can use this +information to make informed choices about the best way to persist data from +your applications and avoid performance problems along the way. + +## Storage drivers versus Docker volumes + +Docker uses storage drivers to store image layers, and to store data in the +writable layer of a container. The container's writable layer doesn't persist +after the container is deleted, but is suitable for storing ephemeral data that +is generated at runtime. Storage drivers are optimized for space efficiency, but +(depending on the storage driver) write speeds are lower than native file system +performance, especially for storage drivers that use a copy-on-write filesystem. +Write-intensive applications, such as database storage, are impacted by a +performance overhead, particularly if pre-existing data exists in the read-only +layer. + +Use Docker volumes for write-intensive data, data that must persist beyond the +container's lifespan, and data that must be shared between containers. Refer to +the [volumes section](../volumes.md) to learn how to use volumes to persist data +and improve performance. + +## Images and layers + +A Docker image is built up from a series of layers. Each layer represents an +instruction in the image's Dockerfile. Each layer except the very last one is +read-only. Consider the following Dockerfile: + +```dockerfile +# syntax=docker/dockerfile:1 + +FROM ubuntu:22.04 +LABEL org.opencontainers.image.authors="org@example.com" +COPY . /app +RUN make /app +RUN rm -r $HOME/.cache +CMD python /app/app.py +``` + +This Dockerfile contains four commands. Commands that modify the filesystem create +a new layer. The `FROM` statement starts out by creating a layer from the `ubuntu:22.04` +image. The `LABEL` command only modifies the image's metadata, and doesn't produce +a new layer. The `COPY` command adds some files from your Docker client's current +directory. The first `RUN` command builds your application using the `make` command, +and writes the result to a new layer. The second `RUN` command removes a cache +directory, and writes the result to a new layer. Finally, the `CMD` instruction +specifies what command to run within the container, which only modifies the +image's metadata, which doesn't produce an image layer. + +Each layer is only a set of differences from the layer before it. Note that both +_adding_, and _removing_ files will result in a new layer. In the example above, +the `$HOME/.cache` directory is removed, but will still be available in the +previous layer and add up to the image's total size. Refer to the +[Best practices for writing Dockerfiles](/manuals/build/building/best-practices.md) +and [use multi-stage builds](/manuals/build/building/multi-stage.md) +sections to learn how to optimize your Dockerfiles for efficient images. + +The layers are stacked on top of each other. When you create a new container, +you add a new writable layer on top of the underlying layers. This layer is often +called the "container layer". All changes made to the running container, such as +writing new files, modifying existing files, and deleting files, are written to +this thin writable container layer. The diagram below shows a container based +on an `ubuntu:15.04` image. + +![Layers of a container based on the Ubuntu image](images/container-layers.webp?w=450&h=300) + +A storage driver handles the details about the way these layers interact with +each other. Different storage drivers are available, which have advantages +and disadvantages in different situations. + +## Container and layers + +The major difference between a container and an image is the top writable layer. +All writes to the container that add new or modify existing data are stored in +this writable layer. When the container is deleted, the writable layer is also +deleted. The underlying image remains unchanged. + +Because each container has its own writable container layer, and all changes are +stored in this container layer, multiple containers can share access to the same +underlying image and yet have their own data state. The diagram below shows +multiple containers sharing the same Ubuntu 15.04 image. + +![Containers sharing the same image](images/sharing-layers.webp?w=600&h=300) + +Docker uses storage drivers to manage the contents of the image layers and the +writable container layer. Each storage driver handles the implementation +differently, but all drivers use stackable image layers and the copy-on-write +(CoW) strategy. + +> [!NOTE] +> +> Use Docker volumes if you need multiple containers to have shared access to +> the exact same data. Refer to the [volumes section](../volumes.md) to learn +> about volumes. + +## Container size on disk + +To view the approximate size of a running container, you can use the `docker ps -s` +command. Two different columns relate to size. + +- `size`: the amount of data (on disk) that's used for the writable layer of + each container. +- `virtual size`: the amount of data used for the read-only image data + used by the container plus the container's writable layer `size`. + Multiple containers may share some or all read-only + image data. Two containers started from the same image share 100% of the + read-only data, while two containers with different images which have layers + in common share those common layers. Therefore, you can't just total the + virtual sizes. This over-estimates the total disk usage by a potentially + non-trivial amount. + +The total disk space used by all of the running containers on disk is some +combination of each container's `size` and the `virtual size` values. If +multiple containers started from the same exact image, the total size on disk for +these containers would be SUM (`size` of containers) plus one image size +(`virtual size` - `size`). + +This also doesn't count the following additional ways a container can take up +disk space: + +- Disk space used for log files stored by the [logging-driver](/manuals/engine/logging/_index.md). + This can be non-trivial if your container generates a large amount of logging + data and log rotation isn't configured. +- Volumes and bind mounts used by the container. +- Disk space used for the container's configuration files, which are typically + small. +- Memory written to disk (if swapping is enabled). +- Checkpoints, if you're using the experimental checkpoint/restore feature. + +## The copy-on-write (CoW) strategy + +Copy-on-write is a strategy of sharing and copying files for maximum efficiency. +If a file or directory exists in a lower layer within the image, and another +layer (including the writable layer) needs read access to it, it just uses the +existing file. The first time another layer needs to modify the file (when +building the image or running the container), the file is copied into that layer +and modified. This minimizes I/O and the size of each of the subsequent layers. +These advantages are explained in more depth below. + +### Sharing promotes smaller images + +When you use `docker pull` to pull down an image from a repository, or when you +create a container from an image that doesn't yet exist locally, each layer is +pulled down separately, and stored in Docker's local storage area, which is +usually `/var/lib/docker/` on Linux hosts. You can see these layers being pulled +in this example: + +```console +$ docker pull ubuntu:22.04 +22.04: Pulling from library/ubuntu +f476d66f5408: Pull complete +8882c27f669e: Pull complete +d9af21273955: Pull complete +f5029279ec12: Pull complete +Digest: sha256:6120be6a2b7ce665d0cbddc3ce6eae60fe94637c6a66985312d1f02f63cc0bcd +Status: Downloaded newer image for ubuntu:22.04 +docker.io/library/ubuntu:22.04 +``` + +Each of these layers is stored in its own directory inside the Docker host's +local storage area. To examine the layers on the filesystem, list the contents +of `/var/lib/docker/`. This example uses the `overlay2` +storage driver: + +```console +$ ls /var/lib/docker/overlay2 +16802227a96c24dcbeab5b37821e2b67a9f921749cd9a2e386d5a6d5bc6fc6d3 +377d73dbb466e0bc7c9ee23166771b35ebdbe02ef17753d79fd3571d4ce659d7 +3f02d96212b03e3383160d31d7c6aeca750d2d8a1879965b89fe8146594c453d +ec1ec45792908e90484f7e629330666e7eee599f08729c93890a7205a6ba35f5 +l +``` + +The directory names don't correspond to the layer IDs. + +Now imagine that you have two different Dockerfiles. You use the first one to +create an image called `acme/my-base-image:1.0`. + +```dockerfile +# syntax=docker/dockerfile:1 +FROM alpine +RUN apk add --no-cache bash +``` + +The second one is based on `acme/my-base-image:1.0`, but has some additional +layers: + +```dockerfile +# syntax=docker/dockerfile:1 +FROM acme/my-base-image:1.0 +COPY . /app +RUN chmod +x /app/hello.sh +CMD /app/hello.sh +``` + +The second image contains all the layers from the first image, plus new layers +created by the `COPY` and `RUN` instructions, and a read-write container layer. +Docker already has all the layers from the first image, so it doesn't need to +pull them again. The two images share any layers they have in common. + +If you build images from the two Dockerfiles, you can use `docker image ls` and +`docker image history` commands to verify that the cryptographic IDs of the shared +layers are the same. + +1. Make a new directory `cow-test/` and change into it. + +2. Within `cow-test/`, create a new file called `hello.sh` with the following contents. + + ```bash + #!/usr/bin/env bash + echo "Hello world" + ``` + +3. Copy the contents of the first Dockerfile above into a new file called + `Dockerfile.base`. + +4. Copy the contents of the second Dockerfile above into a new file called + `Dockerfile`. + +5. Within the `cow-test/` directory, build the first image. Don't forget to + include the final `.` in the command.

The process starts + at the newest layer and works down to the base layer one layer at a time. + When results are found, they're added to a cache to speed future operations. +* Perform a `copy_up` operation on the first copy of the file that's found, to + copy the file to the container's writable layer. +* Any modifications are made to this copy of the file, and the container can't + see the read-only copy of the file that exists in the lower layer. + +Btrfs, ZFS, and other drivers handle the copy-on-write differently. You can +read more about the methods of these drivers later in their detailed +descriptions. + +Containers that write a lot of data consume more space than containers +that don't. This is because most write operations consume new space in the +container's thin writable top layer. Note that changing the metadata of files, +for example, changing file permissions or ownership of a file, can also result +in a `copy_up` operation, therefore duplicating the file to the writable layer. + +> [!TIP] +> +> Use volumes for write-heavy applications. +> +> Don't store the data in the container for write-heavy applications. Such +> applications, for example write-intensive databases, are known to be +> problematic particularly when pre-existing data exists in the read-only +> layer. +> +> Instead, use Docker volumes, which are independent of the running container, +> and designed to be efficient for I/O. In addition, volumes can be shared +> among containers and don't increase the size of your container's writable +> layer. Refer to the [use volumes](../volumes.md) section to learn about +> volumes. + +A `copy_up` operation can incur a noticeable performance overhead. This overhead +is different depending on which storage driver is in use. Large files, +lots of layers, and deep directory trees can make the impact more noticeable. +This is mitigated by the fact that each `copy_up` operation only occurs the first +time a given file is modified. + +To verify the way that copy-on-write works, the following procedure spins up 5 +containers based on the `acme/my-final-image:1.0` image we built earlier and +examines how much room they take up. + +1.

You +can see the order in the [source code for Docker Engine {{% param "docker_ce_version" %}}](https://github.com/moby/moby/blob/v{{% param "docker_ce_version" %}}/daemon/graphdriver/driver_linux.go#L52-L53). +{ #storage-driver-order } + + + +Some storage drivers require you to use a specific format for the backing filesystem. +If you have external requirements to use a specific backing filesystem, this may +limit your choices. See [Supported backing filesystems](#supported-backing-filesystems). + +After you have narrowed down which storage drivers you can choose from, your choice +is determined by the characteristics of your workload and the level of stability +you need. See [Other considerations](#other-considerations) for help in making +the final decision. + +## Supported storage drivers per Linux distribution + +> [!NOTE] +> Modifying the storage driver by editing the daemon configuration file isn't +> supported on Docker Desktop. Docker Desktop uses the +> [containerd image store](/manuals/desktop/features/containerd.md) by default +> (version 4.34 and later for clean installs). The following table is also not +> applicable for the Docker Engine in rootless mode. For the drivers available +> in rootless mode, see the +> [Rootless mode documentation](/manuals/engine/security/rootless.md). + +This section applies to classic storage drivers only. If you're using the +containerd image store (the default for Docker Engine 29.0+), see the +[containerd image store documentation](../containerd.md) instead. + +Your operating system and kernel may not support every classic storage driver. +For example, `btrfs` is only supported if your system uses `btrfs` as storage. +In general, the following configurations work on recent versions of the Linux +distribution: + +| Linux distribution | Default classic driver | Alternative drivers | +| :------------------- | :---------------------- | :------------------- | +| Ubuntu | `overlay2` | `zfs`, `vfs` | +| Debian | `overlay2` | `vfs` | +| CentOS | `overlay2` | `zfs`, `vfs` | +| Fedora | `overlay2` | `zfs`, `vfs` | +| SLES 15 | `overlay2` | `vfs` | +| RHEL | `overlay2` | `vfs` | + +For systems using classic storage drivers, `overlay2` provides broad +compatibility across Linux distributions. Use Docker volumes for write-heavy +workloads instead of relying on writing data to the container's writable layer. + +The `vfs` storage driver is usually not the best choice, and primarily intended +for debugging purposes in situations where no other storage-driver is supported. +Before using the `vfs` storage driver, be sure to read about +[its performance and storage characteristics and limitations](vfs-driver.md). + +The recommendations in the table above are known to work for a large number of +users. If you use a recommended configuration and find a reproducible issue, +it's likely to be fixed very quickly. If the driver that you want to use is +not recommended according to this table, you can run it at your own risk. You +can and should still report any issues you run into. However, such issues +have a lower priority than issues encountered when using a recommended +configuration. + +Depending on your Linux distribution, other storage-drivers, such as `btrfs` may +be available. These storage drivers can have advantages for specific use-cases, +but may require additional set-up or maintenance, which make them not recommended +for common scenarios. Refer to the documentation for those storage drivers for +details. + +## Supported backing filesystems + +With regard to Docker, the backing filesystem is the filesystem where +`/var/lib/docker/` is located. Some storage drivers only work with specific +backing filesystems. + +| Storage driver | Supported backing filesystems | +| :--------------- | :-----------------------------------------------------| +| `overlay2` | `xfs` with ftype=1, `ext4`, `btrfs`, (and more) | +| `fuse-overlayfs` | any filesystem | +| `btrfs` | `btrfs` | +| `zfs` | `zfs` | +| `vfs` | any filesystem | + +> [!NOTE] +> +> Most filesystems should work if they have the required features. +> Consult [OverlayFS](https://www.kernel.org/doc/html/latest/filesystems/overlayfs.html) +> for more information. + + +## Other considerations + +### Suitability for your workload + +Among other things, each storage driver has its own performance characteristics +that make it more or less suitable for different workloads. Consider the +following generalizations: + +- `overlay2` operates at the file level rather than + the block level. This uses memory more efficiently, but the container's + writable layer may grow quite large in write-heavy workloads. +- Block-level storage drivers such as `btrfs`, and `zfs` perform + better for write-heavy workloads (though not as well as Docker volumes). +- `btrfs` and `zfs` require a lot of memory. +- `zfs` is a good choice for high-density workloads such as PaaS. + +More information about performance, suitability, and best practices is available +in the documentation for each storage driver. + +### Shared storage systems and the storage driver + +If you use SAN, NAS, hardware RAID, or other shared storage systems, those +systems may provide high availability, increased performance, thin +provisioning, deduplication, and compression. In many cases, Docker can work on +top of these storage systems, but Docker doesn't closely integrate with them. + +Each Docker storage driver is based on a Linux filesystem or volume manager. Be +sure to follow existing best practices for operating your storage driver +(filesystem or volume manager) on top of your shared storage system. For +example, if using the ZFS storage driver on top of a shared storage system, be +sure to follow best practices for operating ZFS filesystems on top of that +specific shared storage system. + +### Stability + +For some users, stability is more important than performance. Though Docker +considers all of the storage drivers mentioned here to be stable, some are newer +and are still under active development. In general, `overlay2` provides the +highest stability. + +### Test with your own workloads + +You can test Docker's performance when running your own workloads on different +storage drivers. Make sure to use equivalent hardware and workloads to match +production conditions, so you can see which storage driver offers the best +overall performance. + +## Check your current storage driver + +The detailed documentation for each individual storage driver details all of the +set-up steps to use a given storage driver. + +To see what storage driver Docker is currently using, use `docker info` and look +for the `Storage Driver` line: + +```console +$ docker info + +Containers: 0 +Images: 0 +Storage Driver: overlay2 + Backing Filesystem: xfs +<...> +``` + +To change the storage driver, see the specific instructions for the new storage +driver. Some drivers require additional configuration, including configuration +to physical or logical disks on the Docker host. + +> [!IMPORTANT] +> +> When you change the storage driver, any existing images and containers become +> inaccessible. This is because their layers can't be used by the new storage +> driver. If you revert your changes, you can access the old images and containers +> again, but any that you pulled or created using the new driver are then +> inaccessible. + +## Related information + +- [Storage drivers](./_index.md) +- [`overlay2` storage driver](overlayfs-driver.md) +- [`btrfs` storage driver](btrfs-driver.md) +- [`zfs` storage driver](zfs-driver.md) +- [`windowsfilter` storage driver](windowsfilter-driver.md) diff --git a/content/storage/storagedriver/vfs-driver.md b/content/manuals/engine/storage/drivers/vfs-driver.md similarity index 98% rename from content/storage/storagedriver/vfs-driver.md rename to content/manuals/engine/storage/drivers/vfs-driver.md index 929f59fcd80b..154463745d73 100644 --- a/content/storage/storagedriver/vfs-driver.md +++ b/content/manuals/engine/storage/drivers/vfs-driver.md @@ -1,9 +1,9 @@ --- description: Learn how to optimize your use of VFS driver. keywords: container, storage, driver, vfs -title: Use the VFS storage driver +title: VFS storage driver aliases: -- /engine/userguide/storagedriver/vfs-driver/ + - /storage/storagedriver/vfs-driver/ --- The VFS storage driver isn't a union filesystem.

Volumes are a good choice for the following use cases: + +- Volumes are easier to back up or migrate than bind mounts. +- You can manage volumes using Docker CLI commands or the Docker API. +- Volumes work on both Linux and Windows containers. +- Volumes can be more safely shared among multiple containers. +- New volumes can have their content pre-populated by a container or build. +- When your application requires high-performance I/O. + +Volumes are not a good choice if you need to access the files from the host, as +the volume is completely managed by Docker. Use [bind mounts](bind-mounts.md) +if you need to access files or directories from both containers and the host. + +Volumes are often a better choice than writing data directly to a container, +because a volume doesn't increase the size of the containers using it. Using a +volume is also faster; writing into a container's writable layer requires a +[storage driver](/manuals/engine/storage/drivers/_index.md) to manage the +filesystem. The storage driver provides a union filesystem, using the Linux +kernel. This extra abstraction reduces performance as compared to using +volumes, which write directly to the host filesystem. + +If your container generates non-persistent state data, consider using a +[tmpfs mount](tmpfs.md) to avoid storing the data anywhere permanently, and to +increase the container's performance by avoiding writing into the container's +writable layer. + +Volumes use `rprivate` (recursive private) bind propagation, and bind propagation isn't +configurable for volumes. + +## A volume's lifecycle + +A volume's contents exist outside the lifecycle of a given container.

Docker reuses the same volume when you run the command subsequently. + +You can create a volume directly outside of Compose using `docker volume create` and +then reference it inside `compose.yaml` as follows: + +```yaml +services: + frontend: + image: node:lts + volumes: + - myapp:/home/node/app +volumes: + myapp: + external: true +``` + +For more information about using volumes with Compose, refer to the +[Volumes](/reference/compose-file/volumes.md) +section in the Compose specification. + +### Start a service with volumes + +When you start a service and define a volume, each service container uses its own +local volume. None of the containers can share this data if you use the `local` +volume driver. However, some volume drivers do support shared storage. + +The following example starts an `nginx` service with four replicas, each of which +uses a local volume called `myvol2`. + +```console +$ docker service create -d \ + --replicas=4 \ + --name devtest-service \ + --mount source=myvol2,target=/app \ + nginx:latest +``` + +Use `docker service ps devtest-service` to verify that the service is running: + +```console +$ docker service ps devtest-service + +ID NAME IMAGE NODE DESIRED STATE CURRENT STATE ERROR PORTS +4d7oz1j85wwn devtest-service.1 nginx:latest moby Running Running 14 seconds ago +``` + +You can remove the service to stop the running tasks: + +```console +$ docker service rm devtest-service +``` + +Removing the service doesn't remove any volumes created by the service. +Volume removal is a separate step. + +### Populate a volume using a container + +If you start a container which creates a new volume, and the container +has files or directories in the directory to be mounted such as `/app/`, +Docker copies the directory's contents into the volume. The container then +mounts and uses the volume, and other containers which use the volume also +have access to the pre-populated content. + +To show this, the following example starts an `nginx` container and +populates the new volume `nginx-vol` with the contents of the container's +`/usr/share/nginx/html` directory. This is where Nginx stores its default HTML +content. + +The `--mount` and `-v` examples have the same end result. + +{{< tabs >}} +{{< tab name="`--mount`" >}} + +```console +$ docker run -d \ + --name=nginxtest \ + --mount source=nginx-vol,destination=/usr/share/nginx/html \ + nginx:latest +``` + +{{< /tab >}} +{{< tab name="`-v`" >}} + +```console +$ docker run -d \ + --name=nginxtest \ + -v nginx-vol:/usr/share/nginx/html \ + nginx:latest +``` + +{{< /tab >}} +{{< /tabs >}} + +After running either of these examples, run the following commands to clean up +the containers and volumes. Note volume removal is a separate step. + +```console +$ docker container stop nginxtest + +$ docker container rm nginxtest + +$ docker volume rm nginx-vol +``` + +## Use a read-only volume + +For some development applications, the container needs to write into the bind +mount so that changes are propagated back to the Docker host. At other times, +the container only needs read access to the data. Multiple +containers can mount the same volume. You can simultaneously mount a +single volume as `read-write` for some containers and as `read-only` for others. + +The following example changes the previous one. It mounts the directory as a read-only +volume, by adding `ro` to the (empty by default) list of options, after the +mount point within the container. Where multiple options are present, you can separate +them using commas. + +The `--mount` and `-v` examples have the same result. + +{{< tabs >}} +{{< tab name="`--mount`" >}} + +```console +$ docker run -d \ + --name=nginxtest \ + --mount source=nginx-vol,destination=/usr/share/nginx/html,readonly \ + nginx:latest +``` + +{{< /tab >}} +{{< tab name="`-v`" >}} + +```console +$ docker run -d \ + --name=nginxtest \ + -v nginx-vol:/usr/share/nginx/html:ro \ + nginx:latest +``` + +{{< /tab >}} +{{< /tabs >}} + +Use `docker inspect nginxtest` to verify that Docker created the read-only mount +correctly.

Volume removal is a +separate step. + +```console +$ docker container stop nginxtest + +$ docker container rm nginxtest + +$ docker volume rm nginx-vol +``` + +## Mount a volume subdirectory + +When you mount a volume to a container, you can specify a subdirectory of the +volume to use, with the `volume-subpath` parameter for the `--mount` flag. The +subdirectory that you specify must exist in the volume before you attempt to +mount it into a container; if it doesn't exist, the mount fails. + +Specifying `volume-subpath` is useful if you only want to share a specific +portion of a volume with a container. Say for example that you have multiple +containers running and you want to store logs from each container in a shared +volume. You can create a subdirectory for each container in the shared volume, +and mount the subdirectory to the container. + +The following example creates a `logs` volume and initiates the subdirectories +`app1` and `app2` in the volume. It then starts two containers and mounts one +of the subdirectories of the `logs` volume to each container. This example +assumes that the processes in the containers write their logs to +`/var/log/app1` and `/var/log/app2`. + +```console +$ docker volume create logs +$ docker run --rm \ + --mount src=logs,dst=/logs \ + alpine mkdir -p /logs/app1 /logs/app2 +$ docker run -d \ + --name=app1 \ + --mount src=logs,dst=/var/log/app1,volume-subpath=app1 \ + app1:latest +$ docker run -d \ + --name=app2 \ + --mount src=logs,dst=/var/log/app2,volume-subpath=app2 \ + app2:latest +``` + +With this setup, the containers write their logs to separate subdirectories of +the `logs` volume. The containers can't access the other container's logs. + +## Share data between machines + +When building fault-tolerant applications, you may need to configure multiple +replicas of the same service to have access to the same files. + +![shared storage](images/volumes-shared-storage.webp) + +There are several ways to achieve this when developing your applications. +One is to add logic to your application to store files on a cloud object +storage system like Amazon S3. Another is to create volumes with a driver that +supports writing files to an external storage system like NFS or Amazon S3. + +Volume drivers let you abstract the underlying storage system from the +application logic. For example, if your services use a volume with an NFS +driver, you can update the services to use a different driver. For example, to +store data in the cloud, without changing the application logic. + +## Use a volume driver + +When you create a volume using `docker volume create`, or when you start a +container which uses a not-yet-created volume, you can specify a volume driver. +The following examples use the `rclone/docker-volume-rclone` volume driver, first when creating +a standalone volume, and then when starting a container which creates a new +volume. + +> [!NOTE] +> +> If your volume driver accepts a comma-separated list as an option, +> you must escape the value from the outer CSV parser.

Create a file and allocate some space to it: + + ```console + $ fallocate -l 1G disk.raw + ``` + +2. Build a filesystem onto the `disk.raw` file: + + ```console + $ mkfs.ext4 disk.raw + ``` + +3. Create a loop device: + + ```console + $ losetup -f --show disk.raw + /dev/loop5 + ``` + + > [!NOTE] + > + > `losetup` creates an ephemeral loop device that's removed after + > system reboot, or manually removed with `losetup -d`. + +4. Run a container that mounts the loop device as a volume: + + ```console + $ docker run -it --rm \ + --mount='type=volume,dst=/external-drive,volume-driver=local,volume-opt=device=/dev/loop5,volume-opt=type=ext4' \ + ubuntu bash + ``` + + When the container starts, the path `/external-drive` mounts the + `disk.raw` file from the host filesystem as a block device. + +5. When you're done, and the device is unmounted from the container, + detach the loop device to remove the device from the host system: + + ```console + $ losetup -d /dev/loop5 + ``` + +## Back up, restore, or migrate data volumes + +Volumes are useful for backups, restores, and migrations. +Use the `--volumes-from` flag to create a new container that mounts that volume. + +### Back up a volume + +For example, create a new container named `dbstore`: + +```console +$ docker run -v /dbdata --name dbstore ubuntu /bin/bash +``` + +In the next command: + +- Launch a new container and mount the volume from the `dbstore` container +- Mount a local host directory as `/backup` +- Pass a command that tars the contents of the `dbdata` volume to a `backup.tar` file inside the `/backup` directory. + +```console +$ docker run --rm --volumes-from dbstore -v $(pwd):/backup ubuntu tar cvf /backup/backup.tar /dbdata +``` + +When the command completes and the container stops, it creates a backup of +the `dbdata` volume. + +### Restore volume from a backup + +With the backup just created, you can restore it to the same container, +or to another container that you created elsewhere. + +For example, create a new container named `dbstore2`: + +```console +$ docker run -v /dbdata --name dbstore2 ubuntu /bin/bash +``` + +Then, un-tar the backup file in the new container’s data volume: + +```console +$ docker run --rm --volumes-from dbstore2 -v $(pwd):/backup ubuntu bash -c "cd /dbdata && tar xvf /backup/backup.tar --strip 1" +``` + +You can use these techniques to automate backup, migration, and restore +testing using your preferred tools. + +## Remove volumes + +A Docker data volume persists after you delete a container. There are two types +of volumes to consider: + +- Named volumes have a specific source from outside the container, for example, `awesome:/bar`. +- Anonymous volumes have no specific source.

Use the Docker CLI to create a swarm, deploy +application services to a swarm, and manage swarm behavior. + +Docker Swarm mode is built into the Docker Engine. Do not confuse Docker Swarm mode +with [Docker Classic Swarm](https://github.com/docker/classicswarm) +which is no longer actively developed. + +## Feature highlights + +### Cluster management integrated with Docker Engine + +Use the Docker Engine CLI to create a swarm of Docker Engines where you can deploy application +services. You don't need additional orchestration software to create or manage +a swarm. + +### Decentralized design + +Instead of handling differentiation between node roles at deployment time, the Docker Engine handles any specialization at runtime. You can deploy both kinds of nodes, managers and workers, using the +Docker Engine. This means you can build an entire swarm from a single disk +image. + +### Declarative service model + +Docker Engine uses a declarative approach to +let you define the desired state of the various services in your application +stack. For example, you might describe an application comprised of a web front +end service with message queueing services and a database backend. + +### Scaling + +For each service, you can declare the number of tasks you want to +run. When you scale up or down, the swarm manager automatically adapts by +adding or removing tasks to maintain the desired state. + +### Desired state reconciliation + +The swarm manager node constantly monitors +the cluster state and reconciles any differences between the actual state and your +expressed desired state. For example, if you set up a service to run 10 +replicas of a container, and a worker machine hosting two of those replicas +crashes, the manager creates two new replicas to replace the replicas that +crashed. The swarm manager assigns the new replicas to workers that are +running and available. + +### Multi-host networking + +You can specify an overlay network for your +services. The swarm manager automatically assigns addresses to the containers +on the overlay network when it initializes or updates the application. + +### Service discovery + +Swarm manager nodes assign each service in the swarm a +unique DNS name and load balance running containers. You can query every +container running in the swarm through a DNS server embedded in the swarm. + +### Load balancing + +You can expose the ports for services to an +external load balancer. Internally, the swarm lets you specify how to distribute +service containers between nodes. + +### Secure by default + +Each node in the swarm enforces TLS mutual +authentication and encryption to secure communications between itself and all +other nodes. You have the option to use self-signed root certificates or +certificates from a custom root CA. + +### Rolling updates + +At rollout time you can apply service updates to nodes +incrementally. The swarm manager lets you control the delay between service +deployment to different sets of nodes.

For more information, refer to + [Deploy services to a swarm](services.md#gmsa-for-swarm). + +## How Docker manages configs + +When you add a config to the swarm, Docker sends the config to the swarm manager +over a mutual TLS connection. The config is stored in the Raft log, which is +encrypted. The entire Raft log is replicated across the other managers, ensuring +the same high availability guarantees for configs as for the rest of the swarm +management data. + +When you grant a newly-created or running service access to a config, the config +is mounted as a file in the container. The location of the mount point within +the container defaults to `/` in Linux containers. In Windows +containers, configs are all mounted into `C:\ProgramData\Docker\configs` and +symbolic links are created to the desired location, which defaults to +`C:\`. + +You can set the ownership (`uid` and `gid`) for the config, using either the +numerical ID or the name of the user or group. You can also specify the file +permissions (`mode`). These settings are ignored for Windows containers. + +- If not set, the config is owned by the user running the container + command (often `root`) and that user's default group (also often `root`). +- If not set, the config has world-readable permissions (mode `0444`), unless a + `umask` is set within the container, in which case the mode is impacted by + that `umask` value. + +You can update a service to grant it access to additional configs or revoke its +access to a given config at any time. + +A node only has access to configs if the node is a swarm manager or if it is +running service tasks which have been granted access to the config. When a +container task stops running, the configs shared to it are unmounted from the +in-memory filesystem for that container and flushed from the node's memory. + +If a node loses connectivity to the swarm while it is running a task container +with access to a config, the task container still has access to its configs, but +cannot receive updates until the node reconnects to the swarm. + +You can add or inspect an individual config at any time, or list all +configs. You cannot remove a config that a running service is +using. See [Rotate a config](configs.md#example-rotate-a-config) for a way to +remove a config without disrupting running services. + +To update or roll back configs more easily, consider adding a version +number or date to the config name. This is made easier by the ability to control +the mount point of the config within a given container. + +To update a stack, make changes to your Compose file, then re-run `docker +stack deploy -c `. If you use a new config in +that file, your services start using them. Keep in mind that configurations +are immutable, so you can't change the file for an existing service. +Instead, you create a new config to use a different file + +You can run `docker stack rm` to stop the app and take down the stack. This +removes any config that was created by `docker stack deploy` with the same stack +name. This removes _all_ configs, including those not referenced by services and +those remaining after a `docker service update --config-rm`. + +## Read more about `docker config` commands + +Use these links to read about specific commands, or continue to the +[example about using configs with a service](#advanced-example-use-configs-with-a-nginx-service). + +- [`docker config create`](/reference/cli/docker/config/create/) +- [`docker config inspect`](/reference/cli/docker/config/inspect/) +- [`docker config ls`](/reference/cli/docker/config/ls/) +- [`docker config rm`](/reference/cli/docker/config/rm/) + +## Examples + +This section includes graduated examples which illustrate how to use +Docker configs. + +> [!NOTE] +> +> These examples use a single-engine swarm and unscaled services for +> simplicity. The examples use Linux containers, but Windows containers also +> support configs. + +### Defining and using configs in compose files + +The `docker stack` command supports defining configs in a Compose file. +However, the `configs` key is not supported for `docker compose`. See +[the Compose file reference](/reference/compose-file/configs.md) for details. + +### Simple example: Get started with configs + +This simple example shows how configs work in just a few commands. For a +real-world example, continue to +[Advanced example: Use configs with a Nginx service](#advanced-example-use-configs-with-a-nginx-service). + +1. Add a config to Docker. The `docker config create` command reads standard + input because the last argument, which represents the file to read the + config from, is set to `-`. + + ```console + $ echo "This is a config" | docker config create my-config - + ``` + +2. Create a `redis` service and grant it access to the config. By default, + the container can access the config at `/my-config`, but + you can customize the file name on the container using the `target` option. + + ```console + $ docker service create --name redis --config my-config redis:alpine + ``` + +3. Verify that the task is running without issues using `docker service ps`. If + everything is working, the output looks similar to this: + + ```console + $ docker service ps redis + + ID NAME IMAGE NODE DESIRED STATE CURRENT STATE ERROR PORTS + bkna6bpn8r1a redis.1 redis:alpine ip-172-31-46-109 Running Running 8 seconds ago + ``` + +4. Get the ID of the `redis` service task container using `docker ps`, so that + you can use `docker container exec` to connect to the container and read the contents + of the config data file, which defaults to being readable by all and has the + same name as the name of the config. The first command below illustrates + how to find the container ID, and the second and third commands use shell + completion to do this automatically. + + ```console + $ docker ps --filter name=redis -q + + 5cb1c2348a59 + + $ docker container exec $(docker ps --filter name=redis -q) ls -l /my-config + + -r--r--r-- 1 root root 12 Jun 5 20:49 my-config + + $ docker container exec $(docker ps --filter name=redis -q) cat /my-config + + This is a config + ``` + +5. Try removing the config. The removal fails because the `redis` service is + running and has access to the config. + + ```console + + $ docker config ls + + ID NAME CREATED UPDATED + fzwcfuqjkvo5foqu7ts7ls578 hello 31 minutes ago 31 minutes ago + + + $ docker config rm my-config + + Error response from daemon: rpc error: code = 3 desc = config 'my-config' is + in use by the following service: redis + ``` + +6. Remove access to the config from the running `redis` service by updating the + service. + + ```console + $ docker service update --config-rm my-config redis + ``` + +7. Repeat steps 3 and 4 again, verifying that the service no longer has access + to the config. The container ID is different, because the + `service update` command redeploys the service. + + ```console + $ docker container exec -it $(docker ps --filter name=redis -q) cat /my-config + + cat: can't open '/my-config': No such file or directory + ``` + +8. Stop and remove the service, and remove the config from Docker. + + ```console + $ docker service rm redis + + $ docker config rm my-config + ``` + +### Simple example: Use configs in a Windows service + +This is a very simple example which shows how to use configs with a Microsoft +IIS service running on Docker for Windows running Windows containers on +Microsoft Windows 10. It is a naive example that stores the webpage in a config. + +This example assumes that you have PowerShell installed. + +1. Save the following into a new file `index.html`. + + ```html + + Hello Docker + +

    Hello Docker! You have deployed a HTML page.

    + + + ``` + +2. If you have not already done so, initialize or join the swarm. + + ```powershell + docker swarm init + ``` + +3. Save the `index.html` file as a swarm config named `homepage`. + + ```powershell + docker config create homepage index.html + ``` + +4. Create an IIS service and grant it access to the `homepage` config. + + ```powershell + docker service create + --name my-iis + --publish published=8000,target=8000 + --config src=homepage,target="\inetpub\wwwroot\index.html" + microsoft/iis:nanoserver + ``` + +5. Access the IIS service at `http://localhost:8000/`. It should serve + the HTML content from the first step. + +6. Remove the service and the config. + + ```powershell + docker service rm my-iis + + docker config rm homepage + ``` + +### Example: Use a templated config + +To create a configuration in which the content will be generated using a +template engine, use the `--template-driver` parameter and specify the engine +name as its argument. The template will be rendered when container is created. + +1. Save the following into a new file `index.html.tmpl`. + + ```html + + Hello Docker + +

    Hello {{ env "HELLO" }}! I'm service {{ .Service.Name }}.

    + + + ``` + +2. Save the `index.html.tmpl` file as a swarm config named `homepage`. Provide + parameter `--template-driver` and specify `golang` as template engine. + + ```console + $ docker config create --template-driver golang homepage index.html.tmpl + ``` + +3. Create a service that runs Nginx and has access to the environment variable + HELLO and to the config. + + ```console + $ docker service create \ + --name hello-template \ + --env HELLO="Docker" \ + --config source=homepage,target=/usr/share/nginx/html/index.html \ + --publish published=3000,target=80 \ + nginx:alpine + ``` + +4. Verify that the service is operational: you can reach the Nginx server, and + that the correct output is being served. + + ```console + $ curl http://0.0.0.0:3000 + + + Hello Docker + +

    Hello Docker! I'm service hello-template.

    + + + ``` + +### Advanced example: Use configs with a Nginx service + +This example is divided into two parts. +[The first part](#generate-the-site-certificate) is all about generating +the site certificate and does not directly involve Docker configs at all, but +it sets up [the second part](#configure-the-nginx-container), where you store +and use the site certificate as a series of secrets and the Nginx configuration +as a config. The example shows how to set options on the config, such as the +target location within the container and the file permissions (`mode`). + +#### Generate the site certificate + +Generate a root CA and TLS certificate and key for your site. For production +sites, you may want to use a service such as `Let’s Encrypt` to generate the +TLS certificate and key, but this example uses command-line tools. This step +is a little complicated, but is only a set-up step so that you have +something to store as a Docker secret. If you want to skip these sub-steps, +you can [use Let's Encrypt](https://letsencrypt.org/getting-started/) to +generate the site key and certificate, name the files `site.key` and +`site.crt`, and skip to +[Configure the Nginx container](#configure-the-nginx-container). + +1. Generate a root key. + + ```console + $ openssl genrsa -out "root-ca.key" 4096 + ``` + +2. Generate a CSR using the root key. + + ```console + $ openssl req \ + -new -key "root-ca.key" \ + -out "root-ca.csr" -sha256 \ + -subj '/C=US/ST=CA/L=San Francisco/O=Docker/CN=Swarm Secret Example CA' + ``` + +3. Configure the root CA. Edit a new file called `root-ca.cnf` and paste + the following contents into it. This constrains the root CA to only sign + leaf certificates and not intermediate CAs. + + ```ini + [root_ca] + basicConstraints = critical,CA:TRUE,pathlen:1 + keyUsage = critical, nonRepudiation, cRLSign, keyCertSign + subjectKeyIdentifier=hash + ``` + +4. Sign the certificate. + + ```console + $ openssl x509 -req -days 3650 -in "root-ca.csr" \ + -signkey "root-ca.key" -sha256 -out "root-ca.crt" \ + -extfile "root-ca.cnf" -extensions \ + root_ca + ``` + +5. Generate the site key. + + ```console + $ openssl genrsa -out "site.key" 4096 + ``` + +6. Generate the site certificate and sign it with the site key. + + ```console + $ openssl req -new -key "site.key" -out "site.csr" -sha256 \ + -subj '/C=US/ST=CA/L=San Francisco/O=Docker/CN=localhost' + ``` + +7. Configure the site certificate. Edit a new file called `site.cnf` and + paste the following contents into it. This constrains the site + certificate so that it can only be used to authenticate a server and + can't be used to sign certificates. + + ```ini + [server] + authorityKeyIdentifier=keyid,issuer + basicConstraints = critical,CA:FALSE + extendedKeyUsage=serverAuth + keyUsage = critical, digitalSignature, keyEncipherment + subjectAltName = DNS:localhost, IP:127.0.0.1 + subjectKeyIdentifier=hash + ``` + +8. Sign the site certificate. + + ```console + $ openssl x509 -req -days 750 -in "site.csr" -sha256 \ + -CA "root-ca.crt" -CAkey "root-ca.key" -CAcreateserial \ + -out "site.crt" -extfile "site.cnf" -extensions server + ``` + +9. The `site.csr` and `site.cnf` files are not needed by the Nginx service, but + you need them if you want to generate a new site certificate. Protect + the `root-ca.key` file. + +#### Configure the Nginx container + +1. Produce a very basic Nginx configuration that serves static files over HTTPS. + The TLS certificate and key are stored as Docker secrets so that they + can be rotated easily. + + In the current directory, create a new file called `site.conf` with the + following contents: + + ```nginx + server { + listen 443 ssl; + server_name localhost; + ssl_certificate /run/secrets/site.crt; + ssl_certificate_key /run/secrets/site.key; + + location / { + root /usr/share/nginx/html; + index index.html index.htm; + } + } + ``` + +2. Create two secrets, representing the key and the certificate. You can store + any file as a secret as long as it is smaller than 500 KB. This allows you + to decouple the key and certificate from the services that use them. + In these examples, the secret name and the file name are the same. + + ```console + $ docker secret create site.key site.key + + $ docker secret create site.crt site.crt + ``` + +3. Save the `site.conf` file in a Docker config. The first parameter is the + name of the config, and the second parameter is the file to read it from. + + ```console + $ docker config create site.conf site.conf + ``` + + List the configs: + + ```console + $ docker config ls + + ID NAME CREATED UPDATED + 4ory233120ccg7biwvy11gl5z site.conf 4 seconds ago 4 seconds ago + ``` + + +4. Create a service that runs Nginx and has access to the two secrets and the + config. Set the mode to `0440` so that the file is only readable by its + owner and that owner's group, not the world. + + ```console + $ docker service create \ + --name nginx \ + --secret site.key \ + --secret site.crt \ + --config source=site.conf,target=/etc/nginx/conf.d/site.conf,mode=0440 \ + --publish published=3000,target=443 \ + nginx:latest \ + sh -c "exec nginx -g 'daemon off;'" + ``` + + Within the running containers, the following three files now exist: + + - `/run/secrets/site.key` + - `/run/secrets/site.crt` + - `/etc/nginx/conf.d/site.conf` + +5. Verify that the Nginx service is running. + + ```console + $ docker service ls + + ID NAME MODE REPLICAS IMAGE + zeskcec62q24 nginx replicated 1/1 nginx:latest + + $ docker service ps nginx + + NAME IMAGE NODE DESIRED STATE CURRENT STATE ERROR PORTS + nginx.1.9ls3yo9ugcls nginx:latest moby Running Running 3 minutes ago + ``` + +6.

Tarball contexts must be tar archives conforming to the standard - `tar` Unix format and can be compressed with any one of the `xz`, `bzip2`, - `gzip` or `identity` (no compression) formats. - - ### Text files - - Instead of specifying a context, you can pass a single `Dockerfile` in the - `URL` or pipe the file in via `STDIN`. To pipe a `Dockerfile` from `STDIN`: - - ```console - $ docker build - < Dockerfile - ``` - - With PowerShell on Windows, you run: - - ```powershell - Get-Content Dockerfile | docker build - - ``` - - If you use `STDIN` or specify a `URL` pointing to a plain text file, the daemon - places the contents into a `Dockerfile`, and ignores any `-f`, `--file` - option. In this scenario, there is no context. - - By default the `docker build` command looks for a `Dockerfile` at the root - of the build context. The `-f`, `--file`, option lets you specify the path to - an alternative file to use instead. This is useful in cases that use the same - set of files for multiple builds. The path must be to a file within the - build context. Relative path are interpreted as relative to the root of the - context. - - In most cases, it's best to put each Dockerfile in an empty directory. Then, - add to that directory only the files needed for building the Dockerfile. To - increase the build's performance, you can exclude files and directories by - adding a `.dockerignore` file to that directory as well. For information on - creating one, see the [.dockerignore file](/reference/dockerfile/#dockerignore-file). - - If the Docker client loses connection to the daemon, it cancels the build. - This happens if you interrupt the Docker client with `CTRL-c` or if the Docker - client is killed for any reason. If the build initiated a pull which is still - running at the time the build is cancelled, the client also cancels the pull. -usage: docker image build [OPTIONS] PATH | URL | - -pname: docker image -plink: docker_image.yaml -options: -

``` - - This example specifies that the `PATH` is `.`, and so `tar`s all the files in the - local directory and sends them to the Docker daemon. The `PATH` specifies - where to find the files for the "context" of the build on the Docker daemon. - Remember that the daemon could be running on a remote machine and that no - parsing of the Dockerfile happens at the client side (where you're running - `docker build`). That means that all the files at `PATH` are sent, not just - the ones listed to [`ADD`](/reference/dockerfile/#add) - in the Dockerfile. - - The transfer of context from the local machine to the Docker daemon is what the - `docker` client means when you see the "Sending build context" message. - - If you wish to keep the intermediate containers after the build is complete, - you must use `--rm=false`. This doesn't affect the build cache. - - ### Build with URL - - ```console - $ docker build github.com/creack/docker-firefox - ``` - - This clones the GitHub repository, using the cloned repository as context, - and the Dockerfile at the root of the repository. You can - specify an arbitrary Git repository by using the `git://` or `git@` scheme. - - ```console - $ docker build -f ctx/Dockerfile http://server/ctx.tar.gz - - Downloading context: http://server/ctx.tar.gz [===================>] 240 B/240 B - Step 1/3 : FROM busybox - ---> 8c2e06607696 - Step 2/3 : ADD ctx/container.cfg / - ---> e7829950cee3 - Removing intermediate container b35224abf821 - Step 3/3 : CMD /bin/ls - ---> Running in fbc63d321d73 - ---> 3286931702ad - Removing intermediate container fbc63d321d73 - Successfully built 377c409b35e4 - ``` - - This sends the URL `http://server/ctx.tar.gz` to the Docker daemon, which - downloads and extracts the referenced tarball. The `-f ctx/Dockerfile` - parameter specifies a path inside `ctx.tar.gz` to the `Dockerfile` used - to build the image. Any `ADD` commands in that `Dockerfile` that refer to local - paths must be relative to the root of the contents inside `ctx.tar.gz`. In the - example above, the tarball contains a directory `ctx/`, so the `ADD - ctx/container.cfg /` operation works as expected. - - ### Build with `-` - - ```console - $ docker build - < Dockerfile - ``` - - This example reads a Dockerfile from `STDIN` without context. Due to the lack of a - context, the command doesn't send contents of any local directory to the Docker daemon. - Since there is no context, a Dockerfile `ADD` only works if it refers to a - remote URL. - - ```console - $ docker build - < context.tar.gz - ``` - - This example builds an image for a compressed context read from `STDIN`. - Supported formats are: `bzip2`, `gzip` and `xz`. - - ### Use a .dockerignore file - - ```console - $ docker build . - - Uploading context 18.829 MB - Uploading context - Step 1/2 : FROM busybox - ---> 769b9341d937 - Step 2/2 : CMD echo Hello world - ---> Using cache - ---> 99cc1ad10469 - Successfully built 99cc1ad10469 - $ echo ".git" > .dockerignore - $ docker build . - Uploading context 6.76 MB - Uploading context - Step 1/2 : FROM busybox - ---> 769b9341d937 - Step 2/2 : CMD echo Hello world - ---> Using cache - ---> 99cc1ad10469 - Successfully built 99cc1ad10469 - ``` - - This example shows the use of the `.dockerignore` file to exclude the `.git` - directory from the context. You can see its effect in the changed size of the - uploaded context. The builder reference contains detailed information on - [creating a .dockerignore file](/reference/dockerfile/#dockerignore-file). - - When using the [BuildKit backend](/build/buildkit/), - `docker build` searches for a `.dockerignore` file relative to the Dockerfile - name. For example, running `docker build -f myapp.Dockerfile .` first looks - for an ignore file named `myapp.Dockerfile.dockerignore`. If it can't find such a file, - if present, it uses the `.dockerignore` file. Using a Dockerfile based - `.dockerignore` is useful if a project contains multiple Dockerfiles that expect - to ignore different sets of files. - - ### Tag an image (-t, --tag) {#tag} - - ```console - $ docker build -t vieux/apache:2.0 . - ``` - - This examples builds in the same way as the previous example, but it then tags the resulting - image. The repository name will be `vieux/apache` and the tag `2.0`. - - [Read more about valid tags](/reference/cli/docker/image/tag/). - - You can apply multiple tags to an image. For example, you can apply the `latest` - tag to a newly built image and add another tag that references a specific - version. - - For example, to tag an image both as `whenry/fedora-jboss:latest` and - `whenry/fedora-jboss:v2.1`, use the following: - - ```console - $ docker build -t whenry/fedora-jboss:latest -t whenry/fedora-jboss:v2.1 . - ``` - - ### Specify a Dockerfile (-f, --file) {#file} - - ```console - $ docker build -f Dockerfile.debug . - ``` - - This uses a file called `Dockerfile.debug` for the build instructions - instead of `Dockerfile`. - - ```console - $ curl example.com/remote/Dockerfile | docker build -f - . - ``` - - The above command uses the current directory as the build context and reads - a Dockerfile from stdin. - - ```console - $ docker build -f dockerfiles/Dockerfile.debug -t myapp_debug . - $ docker build -f dockerfiles/Dockerfile.prod -t myapp_prod . - ``` - - The above commands build the current build context (as specified by the - `.`) twice. Once using a debug version of a `Dockerfile` and once using a - production version. - - ```console - $ cd /home/me/myapp/some/dir/really/deep - $ docker build -f /home/me/myapp/dockerfiles/debug /home/me/myapp - $ docker build -f ../../../../dockerfiles/debug /home/me/myapp - ``` - - These two `docker build` commands do the exact same thing. They both use the - contents of the `debug` file instead of looking for a `Dockerfile` and use - `/home/me/myapp` as the root of the build context. Note that `debug` is in the - directory structure of the build context, regardless of how you refer to it on - the command line. - - > **Note** - > - > `docker build` returns a `no such file or directory` error if the - > file or directory doesn't exist in the uploaded context. This may - > happen if there is no context, or if you specify a file that's - > elsewhere on the Host system. The context is limited to the current - > directory (and its children) for security reasons, and to ensure - > repeatable builds on remote Docker hosts. This is also the reason why - > `ADD ../file` doesn't work. - - ### Use a custom parent cgroup (--cgroup-parent) {#cgroup-parent} - - When you run `docker build` with the `--cgroup-parent` option, the daemon runs the containers - used in the build with the [corresponding `docker run` flag](/reference/cli/docker/container/run/#cgroup-parent). - - ### Set ulimits in container (--ulimit) {#ulimit} - - Using the `--ulimit` option with `docker build` causes the daemon to start each build step's - container using those [`--ulimit` flag values](/reference/cli/docker/container/run/#ulimit). - - ### Set build-time variables (--build-arg) {#build-arg} - - You can use `ENV` instructions in a Dockerfile to define variable values. These - values persist in the built image. Often persistence isn't what you want. Users - want to specify variables differently depending on which host they build an - image on. - - A good example is `http_proxy` or source versions for pulling intermediate - files. The `ARG` instruction lets Dockerfile authors define values that users - can set at build-time using the `--build-arg` flag: - - ```console - $ docker build --build-arg HTTP_PROXY=http://10.20.30.2:1234 --build-arg FTP_PROXY=http://40.50.60.5:4567 . - ``` - - This flag allows you to pass the build-time variables that are - accessed like regular environment variables in the `RUN` instruction of the - Dockerfile. These values don't persist in the intermediate or final images - like `ENV` values do. You must add `--build-arg` for each build argument. - - Using this flag doesn't alter the output you see when the build process echoes the`ARG` lines from the - Dockerfile. - - For detailed information on using `ARG` and `ENV` instructions, see the - [Dockerfile reference](/reference/dockerfile/). - - You can also use the `--build-arg` flag without a value, in which case the daemon - propagates the value from the local environment into the Docker container it's building: - - ```console - $ export HTTP_PROXY=http://10.20.30.2:1234 - $ docker build --build-arg HTTP_PROXY . - ``` - - This example is similar to how `docker run -e` works. Refer to the [`docker run` documentation](/reference/cli/docker/container/run/#env) - for more information. - - ### Optional security options (--security-opt) {#security-opt} - - This flag is only supported on a daemon running on Windows, and only supports - the `credentialspec` option. The `credentialspec` must be in the format - `file://spec.txt` or `registry://keyname`. - - ### Specify isolation technology for container (--isolation) {#isolation} - - This option is useful in situations where you are running Docker containers on - Windows. The `--isolation=<value>` option sets a container's isolation - technology. On Linux, the only supported is the `default` option which uses - Linux namespaces. On Microsoft Windows, you can specify these values: - - - | Value | Description | - |-----------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| - | `default` | Use the value specified by the Docker daemon's `--exec-opt` . If the `daemon` does not specify an isolation technology, Microsoft Windows uses `process` as its default value. | - | `process` | Namespace isolation only. | - | `hyperv` | Hyper-V hypervisor partition-based isolation. | - - Specifying the `--isolation` flag without a value is the same as setting `--isolation="default"`. - - ### Add entries to container hosts file (--add-host) {#add-host} - - You can add other hosts into a build container's `/etc/hosts` file by using one - or more `--add-host` flags. This example adds static addresses for hosts named - `my-hostname` and `my_hostname_v6`: - - ```console - $ docker build --add-host my_hostname=8.8.8.8 --add-host my_hostname_v6=2001:4860:4860::8888 . - ``` - - If you need your build to connect to services running on the host, you can use - the special `host-gateway` value for `--add-host`. In the following example, - build containers resolve `host.docker.internal` to the host's gateway IP. - - ```console - $ docker build --add-host host.docker.internal=host-gateway . - ``` - - You can wrap an IPv6 address in square brackets. - `=` and `:` are both valid separators. - Both formats in the following example are valid: - - ```console - $ docker build --add-host my-hostname:10.180.0.1 --add-host my-hostname_v6=[2001:4860:4860::8888] . - ``` - - ### Specifying target build stage (--target) {#target} - - When building a Dockerfile with multiple build stages, you can use the `--target` - option to specify an intermediate build stage by name as a final stage for the - resulting image. The daemon skips commands after the target stage. - - ```dockerfile - FROM debian AS build-env - # ... - - FROM alpine AS production-env - # ... - ``` - - ```console - $ docker build -t mybuildimage --target build-env . - ``` - - ### Custom build outputs (--output) {#output} - - > **Note** - > - > This feature requires the BuildKit backend. You can either - > [enable BuildKit](/build/buildkit/#getting-started) or - > use the [buildx](https://github.com/docker/buildx) plugin which provides more - > output type options. - - By default, a local container image is created from the build result. The - `--output` (or `-o`) flag allows you to override this behavior, and specify a - custom exporter. Custom exporters allow you to export the build - artifacts as files on the local filesystem instead of a Docker image, which can - be useful for generating local binaries, code generation etc. - - The value for `--output` is a CSV-formatted string defining the exporter type - and options that supports `local` and `tar` exporters. - - The `local` exporter writes the resulting build files to a directory on the client side. The - `tar` exporter is similar but writes the files as a single tarball (`.tar`). - - If you specify no type, the value defaults to the output directory of the local - exporter. Use a hyphen (`-`) to write the output tarball to standard output - (`STDOUT`). - - The following example builds an image using the current directory (`.`) as a build - context, and exports the files to a directory named `out` in the current directory. - If the directory does not exist, Docker creates the directory automatically: - - ```console - $ docker build -o out . - ``` - - The example above uses the short-hand syntax, omitting the `type` options, and - thus uses the default (`local`) exporter. The example below shows the equivalent - using the long-hand CSV syntax, specifying both `type` and `dest` (destination - path): - - ```console - $ docker build --output type=local,dest=out . - ``` - - Use the `tar` type to export the files as a `.tar` archive: - - ```console - $ docker build --output type=tar,dest=out.tar . - ``` - - The example below shows the equivalent when using the short-hand syntax. In this - case, `-` is specified as destination, which automatically selects the `tar` type, - and writes the output tarball to standard output, which is then redirected to - the `out.tar` file: - - ```console - $ docker build -o - . > out.tar - ``` - - The `--output` option exports all files from the target stage. A common pattern - for exporting only specific files is to do multi-stage builds and to copy the - desired files to a new scratch stage with [`COPY --from`](/reference/dockerfile/#copy). - - The example, the `Dockerfile` below uses a separate stage to collect the - build artifacts for exporting: - - ```dockerfile - FROM golang AS build-stage - RUN go get -u github.com/LK4D4/vndr - - FROM scratch AS export-stage - COPY --from=build-stage /go/bin/vndr / - ``` - - When building the Dockerfile with the `-o` option, the command only exports the files from the final - stage to the `out` directory, in this case, the `vndr` binary: - - ```console - $ docker build -o out . - - [+] Building 2.3s (7/7) FINISHED - => [internal] load build definition from Dockerfile 0.1s - => => transferring dockerfile: 176B 0.0s - => [internal] load .dockerignore 0.0s - => => transferring context: 2B 0.0s - => [internal] load metadata for docker.io/library/golang:latest 1.6s - => [build-stage 1/2] FROM docker.io/library/golang@sha256:2df96417dca0561bf1027742dcc5b446a18957cd28eba6aa79269f23f1846d3f 0.0s - => => resolve docker.io/library/golang@sha256:2df96417dca0561bf1027742dcc5b446a18957cd28eba6aa79269f23f1846d3f 0.0s - => CACHED [build-stage 2/2] RUN go get -u github.com/LK4D4/vndr 0.0s - => [export-stage 1/1] COPY --from=build-stage /go/bin/vndr / 0.2s - => exporting to client 0.4s - => => copying files 10.30MB 0.3s - - $ ls ./out - vndr - ``` - - ### Specifying external cache sources (--cache-from) {#cache-from} - - > **Note** - > - > This feature requires the BuildKit backend. You can either - > [enable BuildKit](/build/buildkit/#getting-started) or - > use the [buildx](https://github.com/docker/buildx) plugin. The previous - > builder has limited support for reusing cache from pre-pulled images. - - In addition to local build cache, the builder can reuse the cache generated from - previous builds with the `--cache-from` flag pointing to an image in the registry. - - To use an image as a cache source, cache metadata needs to be written into the - image on creation. You can do this by setting `--build-arg BUILDKIT_INLINE_CACHE=1` - when building the image. After that, you can use the built image as a cache source - for subsequent builds. - - Upon importing the cache, the builder only pulls the JSON metadata from the - registry and determine possible cache hits based on that information. If there - is a cache hit, the builder pulls the matched layers into the local environment. - - In addition to images, the cache can also be pulled from special cache manifests - generated by [`buildx`](https://github.com/docker/buildx) or the BuildKit CLI - (`buildctl`). These manifests (when built with the `type=registry` and `mode=max` - options) allow pulling layer data for intermediate stages in multi-stage builds. - - The following example builds an image with inline-cache metadata and pushes it - to a registry, then uses the image as a cache source on another machine: - - ```console - $ docker build -t myname/myapp --build-arg BUILDKIT_INLINE_CACHE=1 . - $ docker push myname/myapp - ``` - - After pushing the image, the image is used as cache source on another machine. - BuildKit automatically pulls the image from the registry if needed. - - On another machine: - - ```console - $ docker build --cache-from myname/myapp . - ``` - - ### Set the networking mode for the RUN instructions during build (--network) {#network} - - #### Overview - - Available options for the networking mode are: - - - `default` (default): Run in the default network. - - `none`: Run with no network access. - - `host`: Run in the host’s network environment. - - Find more details in the [Dockerfile documentation](/reference/dockerfile/#run---network). - - ### Squash an image's layers (--squash) (experimental) {#squash} - - #### Overview - - > **Note** - > The `--squash` option is an experimental feature, and should not be considered - > stable. - - Once the image is built, this flag squashes the new layers into a new image with - a single new layer. Squashing doesn't destroy any existing image, rather it - creates a new image with the content of the squashed layers. This effectively - makes it look like all `Dockerfile` commands were created with a single layer. - The `--squash` flag preserves the build cache. - - Squashing layers can be beneficial if your Dockerfile produces multiple layers - modifying the same files. For example, files created in one step and - removed in another step. For other use-cases, squashing images may actually have - a negative impact on performance. When pulling an image consisting of multiple - layers, the daemon can pull layers in parallel and allows sharing layers between - images (saving space). - - For most use cases, multi-stage builds are a better alternative, as they give more - fine-grained control over your build, and can take advantage of future - optimizations in the builder. Refer to the [Multi-stage builds](/build/building/multi-stage/) - section for more information. - - #### Known limitations - - The `--squash` option has a number of known limitations: - - - When squashing layers, the resulting image can't take advantage of layer - sharing with other images, and may use significantly more space. Sharing the - base image is still supported. - - When using this option you may see significantly more space used due to - storing two copies of the image, one for the build cache with all the cache - layers intact, and one for the squashed version. - - While squashing layers may produce smaller images, it may have a negative - impact on performance, as a single layer takes longer to extract, and - you can't parallelize downloading a single layer. - - When attempting to squash an image that doesn't make changes to the - filesystem (for example, the Dockerfile only contains `ENV` instructions), - the squash step will fail (see [issue #33823](https://github.com/moby/moby/issues/33823)). - - #### Prerequisites - - The example on this page is using experimental mode in Docker 23.03. - - You can enable experimental mode by using the `--experimental` flag when starting - the Docker daemon or setting `experimental: true` in the `daemon.json` configuration - file. - - By default, experimental mode is disabled. To see the current configuration of - the Docker daemon, use the `docker version` command and check the `Experimental` - line in the `Engine` section: - - ```console - Client: Docker Engine - Community - Version: 23.0.3 - API version: 1.42 - Go version: go1.19.7 - Git commit: 3e7cbfd - Built: Tue Apr 4 22:05:41 2023 - OS/Arch: darwin/amd64 - Context: default - - Server: Docker Engine - Community - Engine: - Version: 23.0.3 - API version: 1.42 (minimum version 1.12) - Go version: go1.19.7 - Git commit: 59118bf - Built: Tue Apr 4 22:05:41 2023 - OS/Arch: linux/amd64 - Experimental: true - [...] - ``` - - #### Build an image with the `--squash` flag - - The following is an example of a build with the `--squash` flag.

This will impact the security of your system; the `docker` group is `root` equivalent. See [Docker Daemon Attack Surface](/engine/security/#docker-daemon-attack-surface) for details. - - You can log in to any public or private repository for which you have - credentials. When you log in, the command stores credentials in - `$HOME/.docker/config.json` on Linux or `%USERPROFILE%/.docker/config.json` on - Windows, via the procedure described below. - - ### Credential stores - - The Docker Engine can keep user credentials in an external credential store, - such as the native keychain of the operating system. Using an external store - is more secure than storing credentials in the Docker configuration file. - - To use a credential store, you need an external helper program to interact - with a specific keychain or external store. Docker requires the helper - program to be in the client's host `$PATH`. - - You can download the helpers from the `docker-credential-helpers` - [releases page](https://github.com/docker/docker-credential-helpers/releases). - Helpers are available for the following credential stores: - - - D-Bus Secret Service - - Apple macOS keychain - - Microsoft Windows Credential Manager - - [pass](https://www.passwordstore.org/) - - #### Configure the credential store - - You need to specify the credential store in `$HOME/.docker/config.json` - to tell the Docker Engine to use it. The value of the config property should be - the suffix of the program to use (i.e. everything after `docker-credential-`). - For example, to use `docker-credential-osxkeychain`: - - ```json - { - "credsStore": "osxkeychain" - } - ``` - - If you are currently logged in, run `docker logout` to remove - the credentials from the file and run `docker login` again. - - #### Default behavior - - By default, Docker looks for the native binary on each of the platforms, i.e. - "osxkeychain" on macOS, "wincred" on windows, and "pass" on Linux. A special - case is that on Linux, Docker will fall back to the "secretservice" binary if - it cannot find the "pass" binary. If none of these binaries are present, it - stores the credentials (i.e. password) in base64 encoding in the config files - described above. - - #### Credential helper protocol - - Credential helpers can be any program or script that follows a very simple protocol. - This protocol is heavily inspired by Git, but it differs in the information shared. - - The helpers always use the first argument in the command to identify the action. - There are only three possible values for that argument: `store`, `get`, and `erase`. - - The `store` command takes a JSON payload from the standard input. That payload carries - the server address, to identify the credential, the user name, and either a password - or an identity token. - - ```json - { - "ServerURL": "https://index.docker.io/v1", - "Username": "david", - "Secret": "passw0rd1" - } - ``` - - If the secret being stored is an identity token, the Username should be set to - `<token>`. - - The `store` command can write error messages to `STDOUT` that the Docker Engine - will show if there was an issue. - - The `get` command takes a string payload from the standard input. That payload carries - the server address that the Docker Engine needs credentials for. This is - an example of that payload: `https://index.docker.io/v1`. - - The `get` command writes a JSON payload to `STDOUT`. Docker reads the user name - and password from this payload: - - ```json - { - "Username": "david", - "Secret": "passw0rd1" - } - ``` - - The `erase` command takes a string payload from `STDIN`. That payload carries - the server address that the Docker Engine wants to remove credentials for. This is - an example of that payload: `https://index.docker.io/v1`. - - The `erase` command can write error messages to `STDOUT` that the Docker Engine - will show if there was an issue. - - ### Credential helpers - - Credential helpers are similar to the credential store above, but act as the - designated programs to handle credentials for specific registries. The default - credential store (`credsStore` or the config file itself) will not be used for - operations concerning credentials of the specified registries. - - #### Configure credential helpers - - If you are currently logged in, run `docker logout` to remove - the credentials from the default store. - - Credential helpers are specified in a similar way to `credsStore`, but - allow for multiple helpers to be configured at a time. Keys specify the - registry domain, and values specify the suffix of the program to use - (i.e. everything after `docker-credential-`). - For example: - - ```json - { - "credHelpers": { - "registry.example.com": "registryhelper", - "awesomereg.example.org": "hip-star", - "unicorn.example.io": "vcbait" - } - } - ``` -deprecated: false -hidden: false -experimental: false -experimentalcli: false -kubernetes: false -swarm: false - diff --git a/data/engine-cli/docker_save.yaml b/data/engine-cli/docker_save.yaml deleted file mode 100644 index 1bda60a52f0e..000000000000 --- a/data/engine-cli/docker_save.yaml +++ /dev/null @@ -1,36 +0,0 @@ -command: docker save -aliases: docker image save, docker save -short: Save one or more images to a tar archive (streamed to STDOUT by default) -long: Save one or more images to a tar archive (streamed to STDOUT by default) -usage: docker save [OPTIONS] IMAGE [IMAGE...] -pname: docker -plink: docker.yaml -options: - - option: output - shorthand: o - value_type: string - description: Write to a file, instead of STDOUT - deprecated: false - hidden: false - experimental: false - experimentalcli: false - kubernetes: false - swarm: false -inherited_options: - - option: help - value_type: bool - default_value: "false" - description: Print usage - deprecated: false - hidden: true - experimental: false - experimentalcli: false - kubernetes: false - swarm: false -deprecated: false -hidden: false -experimental: false -experimentalcli: false -kubernetes: false -swarm: false - diff --git a/data/glossary.yaml b/data/glossary.yaml index 36ba36c05988..7fbad242ddfd 100644 --- a/data/glossary.yaml +++ b/data/glossary.yaml @@ -1,283 +1,78 @@ -īģŋamd64: | - AMD64 is AMD's 64-bit extension of Intel's x86 architecture, and is also - referred to as x86_64 (or x86-64). -arm64: | - ARM64 is the 64-bit extension of the ARM CPU architecture. arm64 architecture - is used in Apple silicon machines. -btrfs: | - btrfs (B-tree file system) is a Linux [filesystem](#filesystem) that Docker - supports as a storage backend.

For more details, see [Docker subscription overview](/subscription/details/). -Docker Team: | - Docker Team is a [Docker subscription](#docker-subscription). Docker Team offers capabilities for collaboration, productivity, and security across organizations. It enables groups of developers to unlock the full power of collaboration and sharing combined with essential security features and team management capabilities. -Docker Trusted Content Program: | - The Docker Trusted Content Program verifies content through four programs, [Docker Official Images](#docker-official-images), [Docker Verified Publisher Images](#docker-verified-publisher-images), [Docker Open Source Images](#docker-open-source-images), and Custom Official Images. -Docker Verified Publisher Images: | - Docker Verified Publisher Images are confirmed by Docker to be from a trusted software publishers that are partners in the Verified Publisher program. Docker Verified Publisher Images are identified by the Verified Publisher badge included on the Docker Hub repositories. -Dockerfile: | - A Dockerfile is a text document that contains all the commands you would - normally execute manually in order to build a Docker image. Docker can - build images automatically by reading the instructions from a Dockerfile. -ENTRYPOINT: | - In a Dockerfile, an `ENTRYPOINT` is an optional definition for the first part - of the command to be run. If you want your Dockerfile to be runnable without - specifying additional arguments to the `docker run` command, you must specify - either `ENTRYPOINT`, `CMD`, or both. - - - If `ENTRYPOINT` is specified, it is set to a single command. Most official - Docker images have an `ENTRYPOINT` of `/bin/sh` or `/bin/bash`. Even if you - do not specify `ENTRYPOINT`, you may inherit it from the base image that you - specify using the `FROM` keyword in your Dockerfile. To override the - `ENTRYPOINT` at runtime, you can use `--entrypoint`. The following example - overrides the entrypoint to be `/bin/ls` and sets the `CMD` to `-l /tmp`. - - ```bash - $ docker run --entrypoint=/bin/ls ubuntu -l /tmp - ``` - - - `CMD` is appended to the `ENTRYPOINT`. The `CMD` can be any arbitrary string - that is valid in terms of the `ENTRYPOINT`, which allows you to pass - multiple commands or flags at once. To override the `CMD` at runtime, just - add it after the container name or ID. In the following example, the `CMD` - is overridden to be `/bin/ls -l /tmp`. - - ```bash - $ docker run ubuntu /bin/ls -l /tmp - ``` - - In practice, `ENTRYPOINT` is not often overridden. However, specifying the - `ENTRYPOINT` can make your images more flexible and easier to reuse. -filesystem: | - A file system is the method an operating system uses to name files - and assign them locations for efficient storage and retrieval. - - Examples : - - - Linux : overlay2, extfs, btrfs, zfs - - Windows : NTFS - - macOS : APFS -image: | - Docker images are the basis of [containers](#container). An Image is an - ordered collection of root filesystem changes and the corresponding - execution parameters for use within a container runtime. An image typically - contains a union of layered filesystems stacked on top of each other. An image - does not have state and it never changes. -invitee: | - People who have been invited to join an [organization](#organization), but have not yet accepted their invitation. -layer: | - In an image, a layer is modification to the image, represented by an instruction in the Dockerfile. Layers are applied in sequence to the base image to create the final image. - When an image is updated or rebuilt, only layers that change need to be updated, and unchanged layers are cached locally. This is part of why Docker images are so fast and lightweight. The sizes of each layer add up to equal the size of the final image. -libcontainer: | - libcontainer provides a native Go implementation for creating containers with - namespaces, cgroups, capabilities, and filesystem access controls. It allows - you to manage the lifecycle of the container performing additional operations - after the container is created. -libnetwork: | - libnetwork provides a native Go implementation for creating and managing container network namespaces and other network resources. It manages the networking lifecycle of the container performing additional operations after the container is created. -member: | - The people who have received and accepted invitations to join an [organization](#organization). Member can also refer to members of a [team](#team) within an organization. -namespace: | - A [Linux namespace](https://man7.org/linux/man-pages/man7/namespaces.7.html) - is a Linux kernel feature that isolates and virtualizes system resources. Processes which are restricted to a namespace can only interact with resources or processes that are part of the same namespace. Namespaces - are an important part of Docker's isolation model. Namespaces exist for each type of resource, including `net` (networking), `mnt` (storage), `pid` (processes), `uts` (hostname control), and `user` (UID mapping). For more information about namespaces, see [Docker run reference](/engine/reference/run/) and [Isolate containers with a user namespace](/engine/security/userns-remap/). -node: | - A [node](/engine/swarm/how-swarm-mode-works/nodes/) is a physical or virtual - machine running an instance of the Docker Engine in [swarm mode](#swarm-mode). - - Manager nodes perform swarm management and orchestration duties. By default manager nodes are also worker nodes. - - Worker nodes execute tasks. -organization: | - An organization is a collection of teams and repositories that can be managed together. Docker users become members of an organization when they are assigned to at least one team in the organization. -organization name: | - The organization name, sometimes referred to as the organization namespace or the org ID, is the unique identifier of a Docker organization. -overlay network driver: | - Overlay network driver provides out of the box multi-host network connectivity - for Docker containers in a cluster. -overlay storage driver: | - OverlayFS is a [filesystem](#filesystem) service for Linux which implements a - [union mount](https://en.wikipedia.org/wiki/Union_mount) for other file systems. - It is supported by the Docker daemon as a storage driver. base image: | A base image is an image you designate in a `FROM` directive in a Dockerfile. It defines the starting point for your build. Dockerfile instructions create additional layers on top of the base image. A Dockerfile with the `FROM scratch` directive uses an empty base image. -persistent storage: | - Persistent storage or volume storage provides a way for a user to add a - persistent layer to the running container's file system. This persistent layer - could live on the container host or an external device. The lifecycle of this - persistent layer is not connected to the lifecycle of the container, allowing - a user to retain state. -registry: | - A Registry is a hosted service containing [repositories](#repository) of [images](#image) which responds to the Registry API. - The default registry can be accessed using a browser at [Docker Hub](#docker-hub) or using the `docker search` command. -repository: | - A repository is a set of Docker images. A repository can be shared by pushing it to a [registry](#registry) server. The different images in the repository can be labeled using [tags](#tag). - - Here is an example of the shared [nginx repository](https://hub.docker.com/_/nginx/) and its [tags](https://hub.docker.com/r/library/nginx/tags/). -SSH: | - SSH (secure shell) is a secure protocol for accessing remote machines and applications. - It provides authentication and encrypts data communication over insecure networks such as the Internet. SSH uses public/private key pairs to authenticate logins. -seats: | - The number of seats refers to the number of planned members within an [organization](#organization). -service: | - A [service](/engine/swarm/how-swarm-mode-works/services/) is the definition of how you want to run your application containers in a swarm. At the most basic level, a service defines which container image to run in the swarm and which commands to run in the container. For orchestration purposes, the service defines the "desired state", meaning how many containers to run as tasks and constraints for deploying the containers. +build: | + Build is the process of building Docker images using a Dockerfile. The build + uses a Dockerfile and a "context". The context is the set of files in the + directory in which the image is built. - Frequently a service is a microservice within the context of some larger - application. Examples of services might include an HTTP server, a database, or - any other type of executable program that you wish to run in a distributed - environment. -service account: | - A service account is a Docker ID used for automated management of container images or containerized applications. Service accounts are typically used in automated workflows, and do not share Docker IDs with the members in a Docker Team or Docker Business subscription plan. -service discovery: | - Swarm mode [container discovery](/network/drivers/overlay/#container-discovery) is a DNS component internal to the swarm that automatically assigns each service on an overlay network in the swarm a VIP and DNS entry. Containers on the network share DNS mappings for the service through gossip so any container on the network can access the service through its service name. +container: | + A container is a runnable instance of an image. You can start, stop, move, or + delete a container using the Docker CLI or API. Containers are isolated from + one another and the host system but share the OS kernel. They provide a + lightweight and consistent way to run applications. + +context: | + A Docker context contains endpoint configuration for the Docker CLI to connect + to different Docker environments, such as remote Docker hosts or Docker + Desktop. Use `docker context use` to switch between contexts. + +Docker CLI: | + The Docker CLI is the command-line interface for interacting with the Docker + Engine. It provides commands like `docker run`, `docker build`, `docker ps`, + and others to manage Docker containers, images, and services. + +Docker Compose: | + Docker Compose is a tool for defining and running multi-container Docker + applications using a YAML file (`compose.yaml`). With a single command, you + can start all services defined in the configuration. - You don’t need to expose service-specific ports to make the service available to other services on the same overlay network. The swarm’s internal load balancer automatically distributes requests to the service VIP among the active tasks. -swarm: | - A [swarm](/engine/swarm/) is a cluster of one or more Docker Engines running in [swarm mode](#swarm-mode). -swarm mode: | - [Swarm mode](/engine/swarm/) refers to cluster management and orchestration - features embedded in Docker Engine. When you initialize a new swarm (cluster) or join nodes to a swarm, the Docker Engine runs in swarm mode. -tag: | - A tag is a label applied to a Docker image in a [repository](#repository). - Tags are how various images in a repository are distinguished from each other. -task: | - A [task](/engine/swarm/how-swarm-mode-works/services/#tasks-and-scheduling) is the atomic unit of scheduling within a swarm. A task carries a Docker container and the commands to run inside the container. Manager nodes assign tasks to worker nodes according to the number of replicas set in the service scale. -team: | - A team is a group of Docker users that belong to an [organization](#organization). An organization can have multiple teams. -Union file system: | - Union file systems implement a [union - mount](https://en.wikipedia.org/wiki/Union_mount) and operate by creating - layers. Docker uses union file systems in conjunction with - [copy-on-write](#copy-on-write) techniques to provide the building blocks for - containers, making them very lightweight and fast. +Docker Desktop: | + Docker Desktop is an easy-to-install application for Windows, macOS, and Linux + that provides a local Docker development environment. It includes Docker + Engine, Docker CLI, Docker Compose, and a Kubernetes cluster. - For more on Docker and union file systems, see [Docker and OverlayFS in - practice](/engine/userguide/storagedriver/overlayfs-driver/). +Docker Engine: | + Docker Engine is the client-server technology that creates and runs Docker + containers. It includes the Docker daemon (`dockerd`), REST API, and the + Docker CLI client. - Example implementations of union file systems are - [UnionFS](https://en.wikipedia.org/wiki/UnionFS) and - [OverlayFS](https://en.wikipedia.org/wiki/OverlayFS). -virtual machine: | - A virtual machine is a program that emulates a complete computer and imitates dedicated hardware. - It shares physical hardware resources with other users but isolates the operating system. The end user has the same experience on a Virtual Machine as they would have on dedicated hardware. +Docker Hub: | + Docker Hub is Docker’s public registry service where users can store, share, + and manage container images. It hosts Docker Official Images, Verified + Publisher content, and community-contributed images. - Compared to containers, a virtual machine is heavier to run, provides more isolation, gets its own set of resources and does minimal sharing. +image: | + An image is a read-only template used to create containers. It typically + includes a base operating system and application code packaged together using + a Dockerfile. Images are versioned using tags and can be pushed to or pulled + from a container registry like Docker Hub. - *Also known as VM* -volume: | - A volume is a specially-designated directory within one or more containers - that bypasses the Union File System. Volumes are designed to persist data, - independent of the container's life cycle. Docker therefore never automatically deletes volumes when you remove a container, nor will it "garbage collect" volumes that are no longer referenced by a container. - *Also known as: data volume* +layer: | + In an image, a layer is a modification represented by an instruction in the + Dockerfile. Layers are applied in sequence to the base image to create the + final image. Unchanged layers are cached, making image builds faster and more + efficient. - There are three types of volumes: *host, anonymous, and named*: +multi-architecture image: | + A multi-architecture image is a Docker image that supports multiple CPU + architectures, like `amd64` or `arm64`. Docker automatically pulls the correct + architecture image for your platform when using a multi-arch image. - - A **host volume** lives on the Docker host's filesystem and can be accessed from within the container. +persistent storage: | + Persistent storage or volume storage provides a way for containers to retain + data beyond their lifecycle. This storage can exist on the host machine or an + external storage system and is not tied to the container's runtime. - - A **named volume** is a volume which Docker manages where on disk the volume is created, but it is given a name. +registry: | + A registry is a storage and content delivery system for Docker images. The + default public registry is Docker Hub, but you can also set up private + registries using Docker Distribution. - - An **anonymous volume** is similar to a named volume, however, it can be difficult to refer to the same volume over time when it is an anonymous volume. Docker handles where the files are stored. -x86_64: | - x86_64 (or x86-64) refers to a 64-bit instruction set invented by AMD as an - extension of Intel's x86 architecture. AMD calls its x86_64 architecture, - AMD64, and Intel calls its implementation, Intel 64. +volume: | + A volume is a special directory within a container that bypasses the Union + File System. Volumes are designed to persist data independently of the + container lifecycle. Docker supports host, anonymous, and named volumes. \ No newline at end of file diff --git a/data/languages.yaml b/data/languages.yaml new file mode 100644 index 000000000000..c3cae399d134 --- /dev/null +++ b/data/languages.yaml @@ -0,0 +1,30 @@ +c-sharp: + title: "C#" + icon: https://cdn.jsdelivr.net/gh/devicons/devicon@latest/icons/csharp/csharp-original.svg +cpp: + title: C++ + icon: https://cdn.jsdelivr.net/gh/devicons/devicon@latest/icons/cplusplus/cplusplus-original.svg +go: + title: Go + icon: https://cdn.jsdelivr.net/gh/devicons/devicon@latest/icons/go/go-original.svg +java: + title: Java + icon: https://cdn.jsdelivr.net/gh/devicons/devicon@latest/icons/java/java-original.svg +js: + title: JavaScript + icon: https://cdn.jsdelivr.net/gh/devicons/devicon@latest/icons/javascript/javascript-original.svg +php: + title: PHP + icon: https://cdn.jsdelivr.net/gh/devicons/devicon@latest/icons/php/php-original.svg +python: + title: Python + icon: https://cdn.jsdelivr.net/gh/devicons/devicon@latest/icons/python/python-original.svg +r: + title: R + icon: https://cdn.jsdelivr.net/gh/devicons/devicon@latest/icons/r/r-original.svg +ruby: + title: Ruby + icon: https://cdn.jsdelivr.net/gh/devicons/devicon@latest/icons/ruby/ruby-original.svg +rust: + title: Rust + icon: https://cdn.jsdelivr.net/gh/devicons/devicon@latest/icons/rust/rust-original.svg diff --git a/data/redirects.yml b/data/redirects.yml index c445cb669322..a6a189a58146 100644 --- a/data/redirects.yml +++ b/data/redirects.yml @@ -3,95 +3,40 @@ # used by _plugins/pageless_redirects.rb # -"/desktop/": - - /docker-for-mac/docker-toolbox/ - - /docker-for-windows/docker-toolbox/ - - /kitematic/ - - /kitematic/faq/ - - /kitematic/known-issues/ - - /kitematic/minecraft-server/ - - /kitematic/nginx-web-server/ - - /kitematic/rethinkdb-dev-database/ - - /kitematic/userguide/ - - /machine/ - - /machine/overview/ - - /machine/AVAILABLE_DRIVER_PLUGINS/ - - /machine/DRIVER_SPEC/ - - /machine/RELEASE/ - - /machine/completion/ - - /machine/concepts/ - - /machine/drivers/ - - /machine/drivers/aws/ - - /machine/drivers/azure/ - - /machine/drivers/digital-ocean/ - - /machine/drivers/exoscale/ - - /machine/drivers/gce/ - - /machine/drivers/generic/ - - /machine/drivers/hyper-v/ - - /machine/drivers/index/ - - /machine/drivers/linode/ - - /machine/drivers/openstack/ - - /machine/drivers/os-base/ - - /machine/drivers/rackspace/ - - /machine/drivers/soft-layer/ - - /machine/drivers/virtualbox/ - - /machine/drivers/vm-cloud/ - - /machine/drivers/vm-fusion/ - - /machine/drivers/vsphere/ - - /machine/examples/aws/ - - /machine/examples/index/ - - /machine/examples/ocean/ - - /machine/get-started-cloud/ - - /machine/get-started/ - - /machine/install-machine/ - - /machine/migrate-to-machine/ - - /machine/reference/active/ - - /machine/reference/config/ - - /machine/reference/create/ - - /machine/reference/env/ - - /machine/reference/help/ - - /machine/reference/index/ - - /machine/reference/inspect/ - - /machine/reference/ip/ - - /machine/reference/kill/ - - /machine/reference/ls/ - - /machine/reference/mount/ - - /machine/reference/provision/ - - /machine/reference/regenerate-certs/ - - /machine/reference/restart/ - - /machine/reference/rm/ - - /machine/reference/scp/ - - /machine/reference/ssh/ - - /machine/reference/start/ - - /machine/reference/status/ - - /machine/reference/stop/ - - /machine/reference/upgrade/ - - /machine/reference/url/ - - /machine/release-notes/ - - /mackit/docker-toolbox/ - - /toolbox/ - - /toolbox/faqs/ - - /toolbox/faqs/troubleshoot/ - - /toolbox/overview/ - - /toolbox/toolbox_install_mac/ - - /toolbox/toolbox_install_windows/ - # Use the `/go/` URL prefix to provide "vanity" URLs linking to the # documentation.

Identify the Docker users in your organization. - - If your organization uses device management software, like MDM or JAMF, you may use the device management software to help identify Docker users. See your device management software's documentation for details. You can identify Docker users by checking if Docker Desktop is installed at the following location on each user's machine: - - Mac: `/Applications/Docker.app` - - Windows: `C:\Program Files\Docker\Docker` - - Linux: `/opt/docker-desktop` - - If your organization doesn't use device management software or your users haven't installed Docker Desktop yet, you may survey your users. -2. Instruct all your Docker users in your organization to update their existing Docker account's email address to an address that's in your organization's domain, or to create a new account using an email address in your organization's domain. - - To update an account's email address, instruct your users to sign in to [Docker Hub](https://hub.docker.com), and update the email address to their email address in your organization's domain. - - To create a new account, instruct your users to go [sign up](https://hub.docker.com/signup) using their email address in your organization's domain. -3. Ask your Docker sales representative or [contact sales](https://www.docker.com/pricing/contact-sales/) to get a list of Docker accounts that use an email address in your organization's domain. - -## Step 2: Invite owners - -When you create an organization, you are the only owner. You may optionally add additional owners. Owners can help you onboard and manage your organization. - -To add an owner, invite a user and assign them the owner role. For more details, see [Invite members](/admin/organization/members/). - -## Step 3: Invite members - -When you add users to your organization, you gain visibility into their activity and you can enforce security settings. In addition, members of your organization receive increased pull limits and other organization wide benefits. - -To add a member, invite a user and assign them the member role. For more details, see [Invite members](/admin/organization/members/). - -## Step 4: Manage members with SSO and SCIM - -Configuring SSO and SCIM is optional and only available to Docker Business subscribers. To upgrade a Docker Team subscription to a Docker Business subscription, see [Upgrade your subscription](/subscription/upgrade/). - -You can manage your members in your identity provider and automatically provision them to your Docker organization with SSO and SCIM.
