Does Docker really not allow you to set environment variables? That would be a rather strange design choice, if true. And I always took the config requirement of 12factor to mean you keep it out of source control. Store it wherever you want, be it Chef, Capistrano, or just a shell script you use to deploy, but keep it out of your code.

Docker absolutely let's yiubset and read environment variables either via docker run or via the Docker file with the ENV directive.

Docker does support setting arbitrary environment variables.
