Example usage:

    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:                                    │
    ├──────────────────────────────────────────────────────────┤
    │ control-plane# kubeadm init                              │
    └──────────────────────────────────────────────────────────┘

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

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