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.
