fix(yq): migrate fully to yq v4 syntax

[sbaerlocher]

Overview

DDE internally uses two different Docker versions of yq – one being the latest (latest) and the other an older version 3. This creates unnecessary complications, especially when all images are removed locally and, upon re-downloading with DDE, two different images have to be fetched.

To resolve this issue, the method for parsing the docker-compose file has been updated to use yq v4 syntax, eliminating the dependency on a specific yq v3 Docker image.

Changes

• Migration to yq v4:
  The complex docker run command that used the mikefarah/yq:3 image has been replaced with the _yq eval function. This change ensures compatibility with yq v4 and removes the need to download the specific yq v3 Docker image.

• Adjustment of the yq Query:
  The query has been modified from:
  services.* | head -n1 | sed 's/.*\.//'
  to:
  .services | keys | .[0]
  This update accurately extracts the first service name from the docker-compose.yml file.

• Shell Scripts Update:
  In the file commands/project/shell/root.sh, the query was slightly modified to:
  .services | keys | .[] | head -n1 | sed 's/.*\.//'
  This correction ensures that the intended functionality is maintained.

• Affected Files:
  The changes were applied in the following files:

  • commands/project/exec.sh
  • commands/project/exec/root.sh
  • commands/project/fix-permissions.sh
  • commands/project/shell.sh
  • commands/project/shell/root.sh

Impact

• Functionality:
  The extraction of the first service name from the docker-compose.yml file now relies on the updated yq v4 syntax using the _yq eval function.

• Simplification:
  By removing the dependency on the yq v3 Docker image, the system is simplified, and the need to download multiple images is eliminated.

• Compatibility:
  These changes ensure full compatibility with yq v4 while maintaining the expected behavior.

@sbaerlocher there are some conflicts. Please also pin the yq image version

| head -n1 | sed 's/.*\.//' we can do this with yq too
