Automate All the Boring Kubernetes Operations with Python
If you're looking for more examples beyond what was shown and referenced above, I recommend exploring other popular tools that make use Python Kubernetes client, such kopf - the library for creating Kubernetes operators. I also find it very useful to take a look at tests of the library itself, as it showcases its intended usage such this client test suite.

Kopf 1.31 now supports admission webhooks. Feedback is welcome!
Hello. Kopf (a framework to write Kubernetes operators in Python) 1.31 is released and has finally got admission webhooks — https://github.com/nolar/kopf/releases/tag/1.31.0. I would appreciate some feedback from experienced operator developers on how easy or hard it is to write webhooks now, and what is missing and makes it inconvenient. The docs: https://kopf.readthedocs.io/en/stable/admission/ For a brief preview, it looks like this:
