containers keep all that junk away from my system. how many apps need node.js or ruby and stuff just to preprocess their css? ever managed some legacy php app? instead of putting that junk directly on my machine i just put it in a container. dont need it anymore? cool - docker rmi that shit

Yeah well maybe but some docker config file imply that you know how to configure the postgress, redis, node package manager, nginx and the SSL chain that live in the container by the means of a yaml config file that is in the end another custom layer of abstraction over the original config files. Of course some docker based projects are better than others.
