Docker Networking on Software Gone Wild

A year and a half ago, Docker networking couldn’t span multiple hosts and used NAT with port mapping to expose container-based services to the outside world.

Docker is the hottest Linux container solution these days. Want to know more about it? Matt Oswalt is running Introduction to Docker webinar in a few days.

In August 2014 a small startup decided to change all that. Docker bought them before they managed to get public, and the rest is history.

As expected, the SocketPlane team was extremely busy – it took us almost a year before all the stars aligned and we managed to record a deep dive into next-generation Docker networking.

The most interesting part (for me): the same team worked on an OpenDaylight-based controller solution before started SocketPlane, and decided to use a fully-distributed control plane in their next product instead of a centralized control-plane solution. Another data point supporting my claim that centralized control plane (as opposed to centralized control) works best in marketing whitepapers.

For the rest of the story, listen to Episode 49 of Software Gone Wild, and make sure you stay till the very end where we started discussing running multi-realm Minecraft on a Docker swarm as well as managing a Docker cluster from a Minecraft client.

  1. I also have some vagrant environments that are preconfigured for Docker Multi-host testing:
    https://github.com/DonMills/dockeroverlayvagrant
    A multi node environment using etcd as the key/value store
    https://github.com/DonMills/dockeroverlayvyos
    A similar setup but with multiple networks and a vyos router in the middle to test layer 3
    Enjoy...

  2. BTW if you folks find that adding opaque signaling to BGP has value to you, we can put a request for vendors to get this out and standardized. The implementation overhead is really low, given that it does not introduce any new functionality, and mainly defines a simple frame format to publish with.
