Continuing with Docker

Today I’m continuing to look at Docker.  I am going to look into creating my own images and playing with some existing ones.  I’ve pulled the MySQL image and I’m going to poke around on it.  I might also look at securing a container or the daemon with some keys.

Hold on!  It seems there’s something I don’t quite get about images and containers.  I tried to remove one of the images I downloaded during the tutorial, but I was told it was in use by a container.  I ran “docker ps” and didn’t see any running.  Why are these containers hanging around?  I’ve gotta investigate that.

I found a couple relevant pages.  Here and here.
