I see a lot of 'but why' questions in the thread. When I started to work with Docker for the very first time, I soon realized that it is going to be fantastic for setting up dev environments (I was not that in to VMs anyway). I have put pretty complex setup at work on docker and it made things really simple for people who wants to set it up on their work laptop. Especially the new hires (oh and interns). Of course Docker is more stuff to learn but when it's just a bunch of instructions to follow on a readme file they would just run those and have the system running (mostly without much trouble) and later figure out what this Docker thing really is, if they are in to it.
