if you want o upgrade the host os for any of the node in the kubernetes cluster you need to put the node in maintenance mode .
drain is the sub command . This drain will remove the pods from the node and if the replication is enabled then replication controller will create on another node .
if there is no sufficient resources and if the taint or tolerations docent match then the PODS will be in pending state .
