Dockerfiles

Because Github doesn't point to the right readme on the package page, here's a TOC:

• Node
• Python

Structure

• images/: a directory per Dockerfile
• legacy/: old images pending migration

Build targets are prefixed with build- and test- for publishing and (light) testing respectively.

I don't have a decent testing strategy. Test targets basically try checking if relevant tools exist.

The CI

Only run jobs on changed images. Images are changed if anything in their directory is changed

• On PRs, test targets are built for changed images.
• On merge, build targets are built and pushed to Dockerhub AND GHPR
  • Base image is tagged like:
    • supastuff/${image}:latest
    • supastuff/${image}:${TAG_FROM_BASE_IMAGE}
    • supastuff/${image}:${SHA}
  • Images with extras are tagged like
    • supastuff/${image}:${extra}
    • supastuff/${image}:${extra}-${TAG_FROM_BASE_IMAGE}
    • supastuff/${image}:${extra}-${SHA}

Ideally, I would cache layers so that once PR is merged, the docker push build can just use existing layers... but with a 5GB limit, this may not be that desirable

I should probably consider using semver on image tags instead of SHA...
