At DockerCon in June, we first introduced experimental support for Docker Networking. In Docker 1.9, we are excited to announce that Networking is ready to use in production and works with Swarm and Compose. Networking is a feature of Docker Engine that allows you to create virtual networks and attach containers to them so you can create the network topology that is right for your application. The networked containers can even span multiple hosts, so you don’t have to worry about what host your container lands on. They seamlessly communicate with each other wherever they are - thus enabling true distributed applications. Networking is also pluggable, so you can use any third-party networking driver to power your networks without having to make changes to your application. You can find an up-to-date list of available plugins here and check out these…
