Kubernetes Cluster Upgrades The Hard Way

What are the (high-level) steps required to upgrade a HA kubernetes cluster?

In the spirit of "Kubernetes the Hard Way", what are the manual steps that would form the basis of an automated process to achieve an upgrade of: the control plane components? the worker components?

The official docs assume the use of kubeadm, which is outside the scope of this question.

It depends on how your current installation looks like. If the control plane components are static pods, you need to update the yaml file in the /etc/kubernetes/manifests folder. And if it is systemctl service you need to install the latest version and reload the service.
