First of all thanks for the great tutorial!
When I did the tutorial, I noticed that the folder `/var/lib/kubernetes/` is missing when moving the kubernetes-controller config. I added the `mkdir` statement to the docs.
```
{
+ sudo mkdir -p /var/lib/kubernetes/
sudo mv kube-controller-manager.kubeconfig /var/lib/kubernetes/
}
```
Cheers!
