I want to know the procedure to upgrade a master node where the kubernetes components are installed without kubeadm. I have such a cluster and I am trying to do this using only kubernetes.io/docs support. I could only get through as far downloading the kubectl binary and replacing it with existing one(and restarting the systemd service).
How do I upgrade the other components? Say from version 1.19 to 1.20?. I don’t find any documentation anywhere. All I see is documentation on how to do it with kubeadm.
