FYI: Vagrant can use docker, rendering your argument invalid :) http://docs.vagrantup.com/v2/provisioning/docker.html http://docs.vagrantup.com/v2/provisioning/docker.html Docker is about running isolated environments in reproducible ways. I get a container working just so on my desktop, ship it to an internal registry, where it gets pulled to run on dev and qa. It works identically to how it works on my desktop, then I ship it to production. One image that works the same on all environments. That is what docker was for, developer productivity.
