How to control node parallel updates in OpenShift 4
Issue
- Is there a way to control Node updates in OCP 4?
- Is it possible to set the
maxUnavailablenode in OpenShift 4 to0and wait until having approval, and then set this to1? Would that work? - Is it possible to continue upgrading other nodes in the cluster, if one node cannot be drained?
