Goal

Spin up a Git server with a greater feature set than Gitea. Specifically, I want: - Integrated CI/CD. I would prefer a platform that comes with a 1st party CI/CD solution, rather than plugging in a 3rd party solution. - Container/image registry. Building a locally-hosted registry for images enables better caching. - Enterprise-competitive platform. Getting experience with a platform that competes with other enterprise SCM solutions is more valuable than something designed for a smaller scale.

Plan

1. Create the host mount points for the docker volumes: mkdir -p ~/docker_data/gitlab/data ~/docker_data/gitlab/logs ~/docker_config/gitlab/config
2. Import the default GitLab configuration from the docs.
3. Customize the compose file:
   1. hostname: gitlab.jafner.net
   2. change the external_url under the GITLAB_OMNIBUS_CONFIG env var to https://gitlab.jafner.net
   3. Add the gitlab_rails['gitlab_shell_ssh_port'] = 2229 configuration line under GITLAB_OMNIBUS_CONFIG with a new SSH port
   4. Remove http and https port bindings. Move host SSH port binding to a higher port.
   5. Change the volume bindings to match my conventions (DOCKER_DATA instead of GITLAB_HOME)
   6. Change the docker compose version to '3.3'
   7. Add Traefik labels to enable TLS.
4. Run the file and test.
5. Troubleshoot issues.
6. GOTO 4.
7. Import Gitea repos
8. Move Gitea from git.jafner.net to gitea.jafner.net
9. Update Homer with new service locations
