They come in specific types. For 20 example, a [volume plugin](plugins_volume.md) might enable Docker 21 volumes to persist across multiple Docker hosts and a 22 [network plugin](plugins_network.md) might provide network plumbing. 23 24 Currently Docker supports volume and network driver plugins. In the future it 25 will support additional plugin types. 26 27 ## Installing a plugin 28 29 Follow the instructions in the plugin's documentation. 30 31 ## Finding a plugin 32 33 The following plugins exist: 34 35 * The [Blockbridge plugin](https://github.com/blockbridge/blockbridge-docker-volume) 36 is a volume plugin that provides access to an extensible set of 37 container-based persistent storage options. It supports single and multi-host Docker 38 environments with features that include tenant isolation, automated 39 provisioning, encryption, secure deletion, snapshots and QoS. 40 41 * The [Convoy plugin](https://github.com/rancher/convoy) is a volume plugin for a 42 variety of storage back-ends including device mapper and NFS. It's a simple standalone 43 executable written in Go and provides the framework to support vendor-specific extensions 44 such as snapshots, backups and restore. 45 46 * The [Flocker plugin](https://clusterhq.com/docker-plugin/) is a volume plugin 47 which provides multi-host portable volumes for Docker, enabling you to run 48 databases and other stateful containers and move them around across a cluster 49 of machines. 50 51 * The [GlusterFS plugin](https://github.com/calavera/docker-volume-glusterfs) is 52 another volume plugin that provides multi-host volumes management for Docker 53 using GlusterFS. 54 55 * The [Keywhiz plugin](https://github.com/calavera/docker-volume-keywhiz) is 56 a plugin that provides credentials and secret management using Keywhiz as 57 a central repository. 58 59 * The [Pachyderm PFS plugin](https://github.com/pachyderm/pachyderm/tree/master/src/cmd/pfs-volume-driver) 60 is a volume plugin written in Go that provides functionality to mount Pachyderm File System (PFS) 61 repositories at specific commits as volumes within Docker containers. 62 63 * The [REX-Ray plugin](https://github.com/emccode/rexraycli) is a volume plugin 64 which is written in Go and provides advanced storage functionality for many 65 platforms including EC2, OpenStack, XtremIO, and ScaleIO. 66 67 ## Troubleshooting a plugin 68 69 If you are having problems with Docker after loading a plugin, ask the authors 70 of the plugin for help. The Docker team may not be able to assist you. 71 72 ## Writing a plugin 73 74 If you are interested in writing a plugin for Docker, or seeing how they work 75 under the hood, see the [docker plugins reference](plugin_api.md).
