feat(ci): add greenhouse PR preview workflow by ArtieReus · Pull Request #1679 · cloudoperators/juno

ArtieReus · 2026-05-08T11:31:05Z

Summary

Add a new GitHub Actions workflow to build Docker images for Greenhouse PR previews. The workflow builds images when the greenhouse-pr-build label is present, manages the greenhouse-pr-preview label for ArgoCD deployment, and cleans up images
when PRs are closed.

Changes Made

Add .github/workflows/build-push-greenhouse-pr-preview.yaml workflow
Workflow triggers on PR label, synchronize, opened, reopened, and closed events
Build job creates Docker image with tag pr-{number}-{sha} when greenhouse-pr-build label is present
On new commits, removes preview label before rebuild and re-adds after success (triggers ArgoCD redeployment)
Cleanup job deletes all PR images using crane when PR is closed/merged
Uses separate image name juno-app-greenhouse-pr-preview to avoid collision with production images
