 Although this example is simple the idea here is to see how you take a container, add new configurations to it and make and image from it to be used in other containers. However, as useful as docker commit is ultimately you will most likely use it rarely and instead will favor the Dockerfile process to build your images. Using docker commit is typically a one time process where you have to create the first container to make the next image. A Dockerfile is a more consistent way to make repeatable images or new images with changes to the Dockerfile options.
