This is an example for creating a Lister using dynamic client for resource of your choice (check code comments for more info).

How it works

All nodes:

$ kubectl get nodes
NAME                            STATUS   ROLES                  AGE   VERSION
k3d-dynamic-corefile-server-0   Ready    control-plane,master   21d   v1.24.4+k3s1

Pods in all the namespaces:

$ kubectl get po -A 
NAMESPACE     NAME                                      READY   STATUS      RESTARTS        AGE

Why did I create this?

This is originally a PoC for a PR I was working on for cluster-autoscaler. I cleaned the code a bit and added comments to make this a generic PoC/example for anyone who wants to use dynamic listers.
