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

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

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

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