Is it safe to yum update docker-ce with containers running in swarm cluster?
I have three Scientific Linux (for this purpose, essentially CentOS) 7 machines configured as a Docker swarm. There is a pending update from docker-ce 18.06 to 18.09. Is it safer to do a process like this on each node in turn:
- set node to "drain"
- reassign leadership of the swarm if this node had it
- do the update of the node
- set the node back to "active"
Or is the RPM update process and the swarm management sufficiently smart that I can just "yum update" each node without worrying about the other steps?
