Questions on Cluster Upgrade. Can someone give me a high level overview of upgrading the cluster?
My understanding is you upgrade the kubeadm tool and then upgrade then run kubeadm upgrade apply <version> then upgrade the kubelet and restart. I am confused as to how do I know how to upgrade the kubeadm tool in the first place. Is there a sequence of commands or is it on a case by case basis?
