Tutorials like this are good for learning, but since computers are great tools which can help to prevent repetitive work it would be great if the author published a virtual machine image or, even better, some saltstack or ansible recipes to build this on github, so it could be improved and maintained by everybody.
Hint to authors of similar tutorials: yes, just release the scripts to build the vm or docker image. This is 2015, it hurts to see 100 of people manually copy pasting things.
