Build kubectl-ng

[jacobtomlinson]

Which project are you requesting an enhancement for?

kr8s

What do you need?

A core goal of kr8s is to provide an experience similar to using kubectl in Python. That means the Python code should be minimal, clean and user focused. There should be no boilerplate code and we should avoid Kubernetes API implementation details from leaking into the code.

To ensure that kr8s has all of the features of kubectl and that the API design matches the expectations folks would bring over from kubectl I started playing around with the kubectl-ng example. This example is a reimplementation of kubectl in Python and uses kr8s as a dependency for interacting with Kubernetes. The goal here is that if we can reimplement kubectl in Python using kr8s then we can ensure that kr8s covers all the came features as kubectl.

To make this more fun I also started playing around with rich which is an awesome library for making beautiful terminal text output in Python. Inspired by projects like k9s I've started playing around with trying to make kubectl-ng more beautiful and interactive at the same time.

As kr8s has matured my tinkering on kubectl-ng has slowed down. But it would be really fun to continue pushing on this so I'm opening a top level issue to track implementing each subcommand from kubectl in kubectl-ng.

Goals:

• Learn more about the Kubernetes API and how kubectl interacts with it
• Find bugs and build out missing functionality in kr8s
• Play with libraries like rich and typer
• Spend time thinking about CLI tool design and how we can make them more beautiful

Non-goals:

• Pairity with kubectl. We aren't trying to replace kubectl, just learn from it and tinker.
