Docksal CI Agent on GitLab issues

[ArtuGit]

I use https://github.com/docksal/ci-agent/blob/develop/README.md as an instruction to establish Docksal CI Agent on GitLab. I have a sandbox server in Digital Ocean,

1. I set up DOCKSAL_HOST_SSH_KEY as a variable in GitLab CI / CD Setting which contains private key for the Sandbox server build account. Is this correct? I have this

2. There is no GitLab example in Project configuration. I suggest adding such an example to the README.md.

I use the following .gitlab-ci.yml:

build_test:
  image: docksal/ci-agent:php
  script:
    - source build-env  # Initialize the agent configuration
    - build-init  # Initialize the remote sandbox environment
    - build-exec "cd www && fin drush st"  # Test performing within the build 
  when: manual

@ArtuGit there is an open issue and a PR for the GitLab CI configuration example.

I don't have a GitLab instance in use, so that PR has been on hold for a while. Check it out and chime in on the implementation.

Regarding DOCKSAL_HOST_SSH_KEY - it has to be base64 encoded.
See https://github.com/docksal/ci-agent#required
