There’s a geeky title for you! But it might help anyone Googling for those keywords…
Recent versions of Docker have many nice new facilities. Here’s a demo of how you can use the service-scaling to run multiple instances of your app back-end, and Nginx as a front-end proxy, while keeping track of them using the round-robin DNS facility built in to the Docker engine.
All demonstrated in a few lines of code on my laptop, using the new Docker for Mac.
Also available on YouTube.
With thanks to Jeppe Toustrup for some helpful hints. Have a look at his page for more detailed information. Also see the Docker channel on YouTube for lots of talks from the recent DockerCon.
Update, spring 2017: Do note that if you’re using Docker Swarm, you may want to adopt a more complex approach, perhaps based on Interlock.

Thank you very much! Your video is very complete, your explanations very clear and the content very, very interesting.
I was searching an easy way to balance servers with docker, and you give me one very simple and clear.
Only an extra question: exists the possibility to automate the containers creation or deletion depending of the load level???
