Hi, in practice test for cluster upgrade process, after following steps to upgrade node01, when I do kubectl get nodes, it still displays v1.18.0 instead of v1. 19.0.Any idea why?

#2

suresh goli:
Because kubelet and kubectl not yet upgraded. <https://v1-19.docs.kubernetes.io/docs/tasks/administer-cluster/kubeadm/kubeadm-upgrade/#upgrade-kubelet-and-kubectl>

Dr Ganesh Neelakanta Iyer:
My command prompt is controlplane$ How do I specify node01 for upgrade?

#4

Dr Ganesh Neelakanta Iyer:
If I understand correctly whenever I am trying to upgrade node01 following the doc, it is upgrading controlplane only

#5

Dr Ganesh Neelakanta Iyer:
@suresh goli @Tej_Singh_Rana any help please?

#6

Dr Ganesh Neelakanta Iyer:
I got the answer. I did not do ssh node01. I was blindly following the official documentation and it didn’t tell that.
