Running In Production With Scissors 
What a fantastic and interesting job you’ve done! I will definitely try!
Question – as far as I understand, you are not using any K8S CNI ( calico, flannel, … ). How your cluster works with multiple nodes ( ip address for pod, connectivity ? )

It is actually using a CNI plugin (https://github.com/containernetworking/plugins) although it just creates a basic bridge for the container network. Most CNI plugins should work fine on this cluster, which does actually have three worker nodes, and I’ve tested pod connectivity between nodes. A simple test for full CNI functionality would be to install Calico and test a NetworkPolicy.
