ALF Docker containers

This repository hosts the Dockerfiles used to build the ALF container images. The build.sh script can be invoked locally or in CI to build every image defined in the tree and push them to the configured registries.

GitHub Actions pipeline

• The workflow at .github/workflows/docker-build.yml builds every image on pushes to main, pull requests, or manual triggers.
• A job matrix spins up parallel runners for the distributions (archlinux, bookworm, bullseye, jupyter, trixie, tumbleweed), each invoking the build script with SELECT_DISTRIBUTION set accordingly.
• Images are published to the GitHub Container Registry namespace ghcr.io/<owner>/<repository>/... when the workflow runs on the default branch or via manual dispatch.
• The workflow relies on the built-in GITHUB_TOKEN and requests the packages: write permission; no additional secrets are required.
• Pull request runs build the images for validation but skip the push step by propagating PUSH_IMAGES=0 to the build script.

Local usage

Run ./build.sh to build all images. Set SELECT_DISTRIBUTION=<name> (with <name> one of archlinux, bookworm, bullseye, jupyter, trixie, tumbleweed) to restrict the build to a single distribution. Set REGISTRY_URL to push to a custom registry and export PUSH_IMAGES=0 for a dry run without pushing.
