Typically on a server, automatic updates of security-related patches are configured. Therefore, if I'm running MySQL 5.5 and a new security patch comes out, Ubuntu Server will apply the upgrade and restart MySQL to keep me protected in an automated way. Obviously, this can be disabled, but it's helpful for those of us who are a bit lazy ;)
Does such a concept exist inside of a Docker container? If I'm running MySQL in a Docker container, do I need to constantly stop the container, open a shell in it, then update and upgrade MySQL?
