Persistence #1

Closed BarnumD closed 7 years ago

BarnumD commented 7 years ago

How do you deal with data persistence? For instance, if the docker service and/or container goes away (docker service rm) where does the data live? How does the cluster recover?

If you specify the volume in docker service create then it would be persisted at whatever source you specified. However, I don't think you should ever need to docker service rm unless you want to tear down the cluster since there is an update command.
