Docker network driver plugins (Engine)

Engine network driver plugins

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. 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.
