Alpha

[seefs001]

Summary by CodeRabbit

• New Features

  • Docker images are now published for multiple architectures (amd64 and arm64).
  • Multi-arch manifests ensure docker pull automatically selects the right image.
  • Expanded tagging: alpha and versioned tags available on both Docker Hub and GHCR.

• Chores

  • Streamlined build and publish pipeline with native per-arch builds and manifest creation.
  • Improved version detection and repository handling for consistent tagging.
  • Enabled caching to speed up image builds and releases.

Walkthrough

The workflow now builds single-architecture images for amd64 and arm64 via a matrix, pushes per-arch tags to Docker Hub and GHCR, then assembles and pushes multi-arch manifests. The Dockerfile adds TARGETOS/TARGETARCH args and explicit GOOS/GOARCH, with GO modules enabled and CGO disabled for multi-arch builds.

Changes

Cohort / File(s)	Summary of Changes
CI/CD workflow: multi-arch build and manifests .github/workflows/docker-image-alpha.yml	Replaces push_to_registries with matrix-based build_single_arch (amd64, arm64) on explicit runners; adds GHCR repo normalization; shallow checkout; explicit Buildx setup; logins to GHCR and Docker Hub; revised metadata targeting GHCR; single-arch build-and-push with expanded tags and cache; adds create_manifests job to assemble/push multi-arch manifests for alpha and versioned tags to both registries; exposes VERSION output.
Dockerfile: arch-aware build settings Dockerfile	Adds ARGs TARGETOS/TARGETARCH; sets ENV GOOS/GOARCH (defaults linux/amd64); explicitly sets GO111MODULE=on and CGO_ENABLED=0; restructures env configuration to support native multi-arch builds without altering runtime commands.

Poem

I hopped through arches, two by two,
amd and arm, a carrot brew. 🥕
I stitched their layers, tag by tag,
then raised a manifest-like flag.
With modules on and CGO nil,
I ship my burrow’s nightly build—thrill!
To GHCR and Hub I fill.
