The "official" Docker workflow looks like this: * Install Docker on your dev machine (remember, there is a Mac version too) * Add a Dockerfile to your source repo, specifying how to assemble a container image from source. * Use a combination of "docker build" and "docker run" to test during development. You can use docker tags to build a separate image for each git commit/tag/branch. * When ready to deploy, use "docker push" to upload your image to a registry (you can run your own, or use the official registry at https://index.docker.io https://index.docker.io). Note the official registry supports private images. * From your production machines (presumably CoreOS but you may have a mix of other distros too) run "docker pull" and "docker run" to deploy your app. * Use Links ("docker rum --link") to interconnect containers, for example your frontend to your database, etc. Mostly if you use Docker for development, you don't need Vagrant. Specifically the Dockerfile is basically a replacement for the Vgrantfile. The caveat is that you can use vagrant for machine deployment to get to a working docker deployment. We used to recommend this but people got confused between the 2, so now we recommend boit2docker instead. I hope this helps.
