CI/CD

The CI/CD infrastructure for Polykey projects is all managed on GitLab.

Setting up Gitlab CI/CD Mirror​

Open source GitHub repositories are mirrored to https://gitlab.com/MatrixAI/open-source in order to execute the CI/CD.

To setup a mirror:

  1. Assume a GitHub repository exists.
  2. Create a repository on GitLab under https://gitlab.com/MatrixAI/open-source.
  3. Go to the repository settings and remove the default mirrored repository and add a new pull mirror:
    • Use the https:// path to the GitHub repository.
    • If the repository is private on GitHub, you will need to use an access token that is part of MatrixAI-Bot. Do not use your personal access token. The username will be MatrixAI-Bot.
    • Enable Overwrite diverged branches.
    • Enable Trigger pipelines for mirror updates.
    • Mirror specific branches: master|staging|feature.* (this is a regular expression).
  4. Under Protected branches and Protected tags:
    • Protect branches master, staging, feature*.
    • Protect tags v*, prerelease*, release*.
    • Only maintainers should be allowed to push and merge.
    • Only feature* is allowed to be force pushed.
  5. Under the CI/CD variables, add in the relevant variables required to execute the .gitlab-ci.yml.
  6. Under Integrations:
    • Enable GitHub as an integration.
    • Provide a commit status token.
    • Enter the relevant repository URL.
    • Enable static status check names.
  7. Ensure the default branch matches the default branch on GitHub. Usually this is staging for both.

You should see CI/CD jobs execute under the Pipelines, and the status of these appear in the GitHub status.

On GitHub add the pipeline status badges to show the status of the CI/CD on GitLab. As an example, the below is the markdown excerpt for https://github.com/MatrixAI/Polykey.

staging:[![pipeline status](https://gitlab.com/MatrixAI/open-source/Polykey/badges/staging/pipeline.svg)](https://gitlab.com/MatrixAI/open-source/Polykey/commits/staging)
master:[![pipeline status](https://gitlab.com/MatrixAI/open-source/Polykey/badges/master/pipeline.svg)](https://gitlab.com/MatrixAI/open-source/Polykey/commits/master)

staging:pipeline status master:pipeline status

This allows us to communicate to others that the CI/CD runs on GitLab.
