• Just as CAPZ has kind-reset to clear our any kind clusters created via kind-create, CAPZ should have a aks-reset make target to clear out any aks-clusters created using aks-create.

Hi, I'm interested on working this issue. Can you tell me the starting point?

Hey @HinaHMS 👋🏼 ! Sure!
Just as we have a make target called kind-reset in CAPZ's makefile, this git issue is to create a similar make target for clearing aks cluster that is created via aks-create make target.

We want to come up with a make target that clears an AKS cluster from a given resource group.
