> It looks interesting but seems like a very Docker-centric Packer I think you mean a Docker-centric Vagrant, no? Packer is for building images, Vagrant is for launching environments. You can use Packer to build Docker images akin to `docker build`, except Packer will let you use a variety of provisioners to build your Docker image like Chef, Ansible, or just simple Bash scripts. It's `docker build` without the Dockerfiles. [1] Docker Machine seems geared towards launching a resource that is ready to run Docker, whether it be a VM running locally or a remote instance in some cloud. It's a single-purpose Vagrant, to really stretch the analogy. :) Once you have a resource that runs Docker, I think that's where Docker Compose [2] steps in. Docker Compose is more like the full Vagrant in that it spins up a full, functioning environment with running services and whatnot.
