Example usage:

Create a two-machine cluster with one master (which controls the cluster),
and one node (where your workloads, like Pods and Deployments run).

┌──────────────────────────────────────────────────────────┐
│ On the first machine:                                    │
├──────────────────────────────────────────────────────────┤
│ master# kubeadm init                                     │
└──────────────────────────────────────────────────────────┘

┌──────────────────────────────────────────────────────────┐
│ On the second machine:                                   │
├──────────────────────────────────────────────────────────┤
│ node# kubeadm join <arguments-returned-from-init>        │
└──────────────────────────────────────────────────────────┘

You can then repeat the second step on as many other machines as you like.
