Project Description

Writing container definition files is boring and error-prone: let's use power of a programming language to generate containers!

Project purpose:

  • Experiment about container creation workflow and container management/publishing/versioning
  • Play with a new non-mainstream programming language and show off capabilities/ease of usage. Ideally I plan to use nim, if time permits also experiment with others
  • Follow Test-Driven Development (TDD) practices
  • Have fun

Advantages:

  • all features of a proper language: variables, multiline strings, logic statements, loops, code reuse.
  • static syntax checking, no more typos or duplicate entries
  • generate many docker files from one template [testing, production, ... ]
  • generate sequence [Dockerfile.suse => Dockerfile.python => Dockerfile.yourapp, ...]
  • could generate command line snippets or CI build scripts with the same data
  • optimize container image creation removing redundant layers

Goal for this Hackweek

Preliminary study and make a proof of concept on a github repo with some working examples

Resources

  • https://github.com/jen-soft/pydocker
  • https://github.com/dahernan/godockerize
  • https://www.mankier.com/5/Containerfile

Further ideas

  • secret scan to avoid API key/tokens leaks
  • optional "runtime" checking
  • extend for multi_stage, docker compose
  • import existing Dockerfile
  • sanitize / check for issues ("linting")
  • iterate on generation by extending to YAML format: k8s manifests, github workflows ...

Looking for hackers with the skills:

nim docker podman containers

      We are currently generating the Dockerfiles for the BCI images via python: https://github.com/SUSE/BCI-dockerfile-generator/tree/main/src/bci_build This is probably not what you are looking for, as it's really just a wrapper around jinja2 templates, but maybe it can help you out a bit.
