SUSE Hack Week: Containerfile / Dockerfile generator library

Project Description

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

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

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

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

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 ...

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.
