Hamdi Khelil enhanced the CI workflow for the pass-culture-main repository by introducing a feature that allows custom deployment source branches for pull request deployments, streamlining the process of fetching Helm charts and reducing manual intervention. This improvement, implemented using Python, YAML, and GitHub Actions, increased deployment reliability and better aligned PR verification with release pipelines. Hamdi also made a minor adjustment to Python debug message formatting within the workflow. Over the course of the month, the work focused on deepening automation and flexibility in CI/CD processes, though the scope was limited to a single feature without additional bug fixes.
