In a container, I don't believe that /tmp will get wiped since the container never technically shuts down. You should clean up /tmp explicitly once you are done running a bundle install.

using a volume is unnecessary if you are copying files in. The volume is nice from a live reload perspective, but the copy is nicer for hosting options if someone wants to throw the container up on an Azure App Service or something. I'm not against setting up a volume AND copying, but I think this could be handled more gracefully (perhaps 2 dockerfiles?).
