@Mumshad Mannambeth / Team,

I am trying to practice kubernetes cluster upgrade procedure on “katacode playground”

controlplane upgrade got success but node upgrade never worked for me. it simply giving an error as kubeadm not found.

I just posted the screenshot as reference. I am wondering this might be related to repo server issue? but it complaining generically just “kubeadm not found”

someone help me on this ? is it a known issue or something which I am doing wrong?

Mohamed Ayman:
the kubeadm upgrade should be executed from the master node to upgrade the worker node

Raj Ravichandran:
thanks for your response, your comment confused me. since I am talking about upgrade kubeadm binary itself.

apt-get command raised an exception as “kubeadm not found” for worker node.
