why can’t we upgrade worker node as same a master by using kubectl upgrade plan?
can you explain what is happening in the last two commands step as we’ve mentioned --kubelet-version=v1.19.0 in 2nd command but we are downloading kubelet in the 3rd command
why cant i uncordon worker node in itself why do i need to do it from master ?
“To minimize downtime, the deployment
gold-nginxshould be rescheduled on an alternate node before upgrading each node.” how are we taking care of this part of the 1st question in the solution.
On Worker Node:-
apt-get install kubeadm=1.19.0-00
kubeadm upgrade node --kubelet-version=v1.19.0
apt-get install kubelet=1.19.0-00
