On Lightning Lab - 1, Q1: After upgrading the cluster controlplane to 1.2.0, I show the nodes and it still shows the controlplane at 1.19.0. I have tried this multiple times to confirm, and I’m following the Cluster Upgrade documentation. Not sure what’s amiss.

Tony Wilmer:
Continuing on, node01 upgrades to 1.20.0 without issue.

Vitor Jr.:
It’s been a while since the last time I did this lab (or upgrade activity) but I think if you restart the process in the controlplane node it will show the correct version after upgrade.

Nikhil Keni:
i found this happens when we forget to upgrade the kubelet

Nikhil Keni:
when we do a get nodes -o wide, the version you see in the table is not the apiserver version, but the kubelet version on that node

Nikhil Keni:
pls do not forget to do a daemon-reload and kubelet restart

unnivkn:
Hi @Tony Wilmer yup… please don’t hurry to check the version, complete all the steps as per the documentation & then try to check the version. https://kubernetes.io/docs/tasks/administer-cluster/kubeadm/kubeadm-upgrade/

Thanks for the responses
