| # We always delete all untagged container images after building an | |
| # image. This way, there should never be stale untagged images laying | |
| # around in the registry. In combination with the workflow that | |
| # deletes PR tags after the PR is closed we should be able to keep the | |
| # container image registry size in check. | |
