I've been developing for a while with a simple Dockerfile in the root of a given project's output... from there I rarely care about it.. in dev, I can mount the app path to the container for dev, and use environment variables set for any other services that are needed. I'm much more productive with Docker for (Windows|Mac) than I've ever been with the likes of vagrant, or whatever bastion of technology that manages VMs... I don't have to think of the VMs, that's generally IT/Infrastructure/DevOps job. yeah, sometimes I wear that hat, but not when I'm coding.
