Page 5: Generating Kubernetes Configuration Files for Authentication
You only need to make two changes to this section: at the very beginning, set KUBERNETES_PUBLIC_ADDRESS=10.240.0.2 instead of using the gcloud command shown, and at the very end when copying files to the VMs. Otherwise, follow the rest of the steps in the original.
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.
