Bazel rules for OCI containers

This is an alternative to rules_docker.

We start from first principles and plan to avoid some pitfalls learned in maintaining that repo:

  • Use a toolchain consisting of off-the-shelf, pre-built layer and container manipulation tools.
  • Don't write language-specific rules, as we cannot be experts on all languages, nor can users deal with the versioning issues that come with dependencies we might take on the rules for those languages.
  • Don't be docker-specific, now that it has a commercial license and other container runtimes exist.
  • Use our toolchain hermetically: don't assume there is a docker pre-installed on the machine.
  • Keep a tight complexity budget for the project so we are able to commit to effective maintenance.
