Does having the shared folder for the DB (the -v switch you mentioned) minimize the security/isolation advantage of what Docker is supposed to be providing?

Yes, that makes sense. And besides it is not a problem in a development environment, it would be better to just share the container file.

But I can't find another way to share containers between host restarts (there is also -volumes-from option for sharing volumes between containers)
