Building a Docker Image Pipeline Using GitHub Actions
summary
Shows a reproducible pipeline that uses GitHub Actions plus Docker’s build-push-action to build and push 49 variant images in parallel (all 49 jobs complete in under five minutes, each image often <60s). Uses one reusable Dockerfile with build ARGs to produce many base variants; a generator creates a workflow matrix, jobs push only on tags and apply add_git_labels so images include revision, source and timestamp. Live demo builds and pushes a new Node 14 tag automatically.
