Define best-practice patterns for bundles when developing with CI/CD

[iyurev]

What needs fixing?

Hi, Is there any the best practices guide which describes common patterns of CI/CD for development and publishing K8S operator ? For example in my case I don't completely understand, do I need to store bundle folder in the git repository with other project files or it'd be better to considering that one as a building artifacts ?

I've seen this done in both ways. I've seen some that will store the bundle with the Operator's project. But I have also seen repos that are just a collection of bundles. Neither one is wrong nor necessarily correct, I think it depends what you want to do with your CI/CD.

I've also noticed repositories which host only operator bundles, and I suppose that I could use the same approach in my CI/CD pipeline.

In my job I'm developing and maintaining several k8s operators and ideally pipeline in each operator's project ( git repository) should can do following things:

1. Build controller manager image ( if it's GO operator the binary file building while for image building in a dedicated stage) and then push one to container registry.
2. Generate operator manifests, build bundle and push it to registry.
3. Add the new bundle to catalog image, rebuild it and push to registry.

I suppose that such workflow is a quite common, and other users could save a lot of time while for operator developing if they have a clear described patterns for CI/CD from documentation of the OLM project.
