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.
