NGINX as a Reverse Proxy for Docker Swarm Clusters

Spawning services across multiple Docker engines is a very cool thing, but those services need to connect each other and be found by public-facing nodes in order to be routed to users. A way to achieve that is to use NGINX as a reverse proxy by defining one or more public-facing nodes. These nodes are going to have NGINX configured to proxy request to each container exposing your service. In this
