└──────────────────────────────────────────────────────────┘
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).
Worker
┌──────────────────────────────────────────────────────────┐
│ On the first machine: |
│ : |
├──────────────────────────────────────────────────────────┤
│ control-plane# kubeadm init │
└──────────────────────────────────────────────────────────┘
┌──────────────────────────────────────────────────────────┐
│ On the second machine: |
│ : |
├──────────────────────────────────────────────────────────┤
│ worker# kubeadm join │
└──────────────────────────────────────────────────────────┘
You can then repeat the second step on as many other machines as you like.
