From the ‘Turtles all the way down’ files:
The concluding session of DockerCon 17, as always at any DockerCon, was all about cool 
hacks. The coolest one for me was Play With Docker (PWD) that quite literally uses Docker to help users learn how to use Docker.
Call it drinking your own champagne, eating your own dogfood – or just call it common sense.
Docker is the easiest way to get an app running and it’s easy to spin up, so why not use Docker to teach Docker?
