# Engine network driver plugins
|
|
|
|
This document describes Docker Engine network driver plugins generally
|
|
available in Docker Engine. To view information on plugins
|
|
managed by Docker Engine, refer to [Docker Engine plugin system](index.md).
|
|
|
|
Docker Engine network plugins enable Engine 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 as a "remote driver" for
|
|
LibNetwork, which shares plugin infrastructure with Engine. Effectively, network
|
|
driver plugins are activated in the same way as other plugins, and use the same
|
|
kind of protocol.
|
|
|
|
## Network driver plugins and swarm mode
|
|
|
|
Docker 1.12 adds support for cluster management and orchestration called
|
|
[swarm mode](../swarm/index.md). Docker Engine running in swarm mode currently
|
|
only supports the built-in overlay driver for networking. Therefore existing
|
|
networking plugins will not work in swarm mode.
|
|
|
|
When you run Docker Engine outside of swarm mode, all networking plugins that
|
|
worked in Docker 1.11 will continue to function normally. They do not require
|
|
any modification.
|
|
|
|
## 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](legacy_plugins.md)
|
|
|
|
The `mynet` network is now owned by `weave`, so subsequent commands
|
|
referring to that network will be sent to the plugin,
|
|
|
|
$ docker run --network=mynet busybox top
|
|
|
|
|
|
## Write a network plugin
|
|
|
|
Network plugins implement the [Docker plugin
|
|
API](https://docs.docker.com/extend/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](https://github.com/docker/libnetwork/blob/master/docs/remote.md).
