Isn't that the case with any tool or service of some complexity? I'd probably have to look at docs or examples for most config files i write.

There's trade-off between a tool being too specific to a usecase vs being too generic with the associated "boilerplate". But I don't know how much simpler Kubernetes could be made while still covering the intended scope?

I would say kubernetes is very simple, in the same way lambda calculus or composing programs out of pipes is simple.

It has very simple basic model, which allows you to recursively built more and more complex abstractions on top of it.
