There are several tools to see the relationship of the docker containers and images. For example, sen is a curses-based, or dockviz is a graphviz-based.
Different from those tools, this command line tool just displays the relationship and the network information. It is not fancy like others, but is enough before you ask the docker inspect command.

Just type docker-tree.py, then you can see the tree like below.

Then, you can use inspect comment for more detail. :)
Currently, this command just take the output of some docker commands. So, it may not work on other platform such as Windows. It may be improved by using the Docker socket API.
