Thank you, Overall LGTM.

Whats the way to test this locally? usually we used to build and load it into kind cluster but now we are creating with static manifest.
Does loading post cluster creation works? or should we use local registry?

Yes, loading post-creation works as kubelet will keep retrying for static-pod. we can keep it for now, once this is released, I'll update the kind-config to refer published image.
