client-go2

Experimenting with k8s.io/client-go and Go generics

This is an experimental type-parameter-aware client that wraps k8s.io/client-go/dynamic (...for now).

Until Go 1.18 is released, use gotip, or the recently released Go 1.18 beta.

Assuming you've got a working kubeconfig (does kubectl get pods work?), you can run this code:

$ go1.18beta1 run ./

THIS IS AN EXPERIMENT

None of this is anywhere near set in stone. The name client-go2 is a placeholder, and a joke.
