Docker is looking better and better... I recently decided to use Python 3.5 and Flask for a project. I didn't have time to learn them and Docker so I used a regular OS X setup. I thought the setup wasn't that bad until I had to share my setup with other team members... It took me 25 minutes to write up a wiki page on just the local environment setup. Pyenv, homebrew, pyenv-virtualenv switcher thing, setting python version, setting environment variables... After reviewing the instructions and going through this with two team members, I am realizing more and more that this is a major barrier to jumping in and out of different technologies easily for teams. We take for granted our environment setups, until you need to have someone else jump into what you're doing. After I get this shipped I'm going to circle back and get it up and running inside Docker. If the promise holds true, one or two commands and you should be up and running for any environment... we'll see.

IIRC Docker on a Mac requires a virtual machine, right? If you're going to use a virtual machine for ordinary development, why not ship around a VM image that has everything pre-installed and ready to go? (This is actually a very sane way of doing development...for much of 2002-2008 I did my development inside a Linux virtual machine running on VMWare Workstation, because my normal laptop was Windows. Macs have spoiled us; since they are POSIX-compatible, we've gotten used to running our dev environment directly on the box. But if you're having trouble configuring everything, it may be worth re-examining the VM solution, because you get much better isolation and many fewer configuration bugs than Docker.)

Docker doesn't 'magic' away the complexity. It just means that operational complexity is handled by fewer team members - the ones that handle the docker ecosystem and keep everything current. And then on top of that, you have to train everyone using it in Docker bullshittery instead of commandline bullshittery.
