Overview
You can extend the capabilities of the Docker Engine by loading third-party plugins.
Types of plugins
Plugins extend Docker's functionality. They come in specific types. For example, a volume plugin might enable Docker volumes to persist across multiple Docker hosts.
Currently Docker supports volume plugins. In the future it will support additional plugin types.
Installing a plugin
Follow the instructions in the plugin's documentation.
Finding a plugin
The following plugins exist:
- The Flocker plugin is a volume plugin which provides multi-host portable volumes for Docker, enabling you to run databases and other stateful containers and move them around across a cluster of machines.
Troubleshooting a plugin
If you are having problems with Docker after loading a plugin, ask the authors of the plugin for help. The Docker team may not be able to assist you.
Writing a plugin
If you are interested in writing a plugin for Docker, or seeing how they work under the hood, see the docker plugins reference.
