Upgrading the kubelet and kubectl on the master node is an important step that I'm glad they included. Can't have a mismatch between the control plane and the client tools!

Haha, 'apt-get install' on a Kubernetes cluster? That's a bold move, Cotton! Let's see if it pays off.

Looks good, but I'm a bit concerned about the `--force` flag in the `drain` command. Is that really necessary? Wouldn't it be better to gracefully stop the pods on the master node?

You're right, but it's always good to consider graceful termination of pods if possible.

I think using the --force flag ensures that all pods are evicted from the node quickly.
