Note: These exact commands were taken out my earlier series of Docker networking 101 posts to show that the command syntax has not changed with the addition of multi-host networking.
To make sure everything still works as expected, let’s run through building a container under each network type. To level set – everything that was there before is still here.
You could start a container in bridge mode by default, host mode my specifying ‘–net=host’, and without an interface by specifying ‘–net=none’. Taking a closer look, you likely notice that these predefined networks are the same as the network models we had in earlier versions of Docker. The networks are permanent and can not be modified. You’ll notice that the Docker CLI now provide a new option to interact with the network through the ‘docker network’ command…Īlright – so let’s start with the basics and see what’s already defined…īy default a base Docker installation has these three networks defined. Before you continue, verify that ‘docker version’ shows you on the correct release.

The default repository had version 1.8 so I had to update to the latest by using the update method shown in a previous post here. Note: I’m running this demo on CentOS 7 boxes. To start with, let’s take a look at a Docker host running the newest version of Docker (1.10).
In this post, we’ll cover the basics of the new network model as well as show some examples of what these new features provide. Docker 1.9 saw the release of user defined networks and the most recent version 1.10 added some additional features. In this post, I’d like to cover some of the new Docker network features.
