I’m currently playing around with a trial of Docker EE 2.0. I setup a 3 manager, 2 worker cluster which was very simple. This was running in VMs on a laptop which I needed to eventually shutdown. I shut down the workers one at a time and then the managers one at a time.
Later I booted the managers up in reverse order, but several of the supporting containers for ucp, etcd, and others were in an unhealthy or restarting status and never recovered.
In situations where there is a need to shutdown and startup an entire cluster, what should the process or order be? Looked around, but other than this, I couldn’t find any info on the subject. This is an uncommon situation in a production setting, but one I’d like to know how to handle if it comes up.
