For my project I am using Tinc to create a VPN that bridges the different per-host local Docker networks. I have described how to do that in a Gist: https://gist.github.com/noteed/11031504

The approach is taken from a blog post where Open vSwitch was used instead of Tinc: http://goldmann.pl/blog/2014/01/21/connecting-docker-contain...

I really like this approach: I run a SkyDNS per group of containers. That DNS is used in `docker run --dns`. Containers can then look up services naturally (via DNS) and those services can actually be running on different machines. Those containers can be running on my laptop or multiple machines across multiple datacenters and there's no difference to them.
