If you've ever used something like virtualbox, that's all docker is, really. You can specify stuff like installing packages, or starting programs, expose ports, in a Dockerfile. You build an image from a Dockerfile. Then you can start "containers" off of the image (starting the virtual machine).
Docker has lots of caveats, but, for the most part, it works pretty well.

I understand VM's I just don't understand how dockers/containers are created how does the file create a container? I am getting old in the tech field... "back in my day" etc... kids with their clouds and containers.
