Seamless Docker Multihost Overlay Networking on DigitalOcean With Machine, Swarm, and Compose ft. RethinkDB

There have been a lot of good articles popping up lately on the new Docker networking features and how to use them with existing Docker tools. So far, most guides will get you through setting up VirtualBox, which is great for getting started, but nothing beats the feeling of getting your hands on an enormous supply of seamlessly networked computing power. So, this article uses Docker Machine, Swarm, and Compose to take it to the cloud and put that power in your hands. I hope to stimulate your imagination as well as set the gears turning for you on some complications and potential solutions for actually putting this stuff out there in the real world.
