Interop with existing k8s control plane/cluster

[nmiculinic]

How does this play with existing k8s cluster, and I want to use k3s for IoT nodes?

If I use flannel (deployed via official CNI) can I also use flannel integration in k3s?

Can I mix control plane nodes in typical k8s installation with worker nodes in k3s?

Can I use k3s hyperkube, rename it to kubelet/kube-proxy and server as a drop-in replacement in the worker node setup?

The k3s binary wrapper is not interchangable with a vanilla k8s control plane. The hyperkube binary that we build is though. You should be able to take hyperkube from releases and copy it to kubelet and get a smaller kubelet footprint. This does mean that you still have to fully manage the kubelet, certs, container runtime, args, etc yourself. But that might be acceptable given your situation.

I guess this closes my comment.
