JConfig is a small webapp that will let you store key value pairs in memory, sql or redis. It comes with a Java client as well as a command line tool. It is intended for small config files and such.

To start the server with default settings (in-memory mode, port 8080, etc):

$ mvn clean package
$ java -jar server/target/jconfig-server.jar

To use the cli with default server settings (localhost:8080)

$ java -jar client/target/jconfig-client.jar -k my_key -v '{"json":"here"}'
$ java -jar client/target/jconfig-client.jar -k my_key -s
{"json":"here"}
$

There is also a higher level bash client for convenient modification of a value. client/src/main/resources/jconfig my_key will open a file in vim with any content associated to the key. On exit the file content will be saved.

#(Work in progress) It's possible to run it in a docker container, and link to another container running a mysql or redis instance.

To run a redis container and then link jconfig to that redis instance, do the following

• mvn clean package
• docker build -t jconfig .
• ./scripts/docker/redis/create-server-container.sh
• ./scripts/docker/jconfig/run-jconfig-redis.sh

To run it against a mysql container instead, you need to set the environment variable JCONFIG_MYSQL_ROOT_PASSWORD that will be used in the docker container.

Then you can do

• mvn clean package
• docker build -t jconfig .
• ./scripts/docker/mysql/create-server-container.sh
• ./scripts/docker/jconfig/run-container.sh
