Goal

Provide a reusable GitHub Actions workflow to build/push multi-arch images to GHCR on tag pushes.

Conventions

  • Use native Intel or ARM runners for CI/CD. Don't use QEMU
  • Use buildx + per-arch digest builds, then merge into a manifest.
  • Use docker/metadata-action for semver tag derivation.

Files

  • .github/workflows/docker-publish.yml
  • .github/workflows/prune-docker-images.yml
