Docker network driver plugins
Docker network plugins enable Docker deployments to be extended to support a wide range of networking technologies, such as VXLAN, IPVLAN, MACVLAN or something completely different. Network driver plugins are supported via the LibNetwork project. Each plugin is implemented asa "remote driver" for LibNetwork, which shares plugin infrastructure with Docker. Effectively, network driver plugins are activated in the same way as other plugins, and use the same kind of protocol.
Using network driver plugins
The means of installing and running a network driver plugin depend on the particular plugin. So, be sure to install your plugin according to the instructions obtained from the plugin developer.
Once running however, network driver plugins are used just like the built-in network drivers: by being mentioned as a driver in network-oriented Docker commands. For example,
$ docker network create --driver weave mynet
Some network driver plugins are listed in plugins
The mynet network is now owned by weave, so subsequent commands
referring to that network will be sent to the plugin,
$ docker run --net=mynet busybox top
Write a network plugin
Network plugins implement the Docker plugin API and the network plugin protocol
Network plugin protocol
The network driver protocol, in addition to the plugin activation call, is documented as part of libnetwork: https://github.com/docker/libnetwork/blob/master/docs/remote.md.
