This page explains the types of plugins and provides links to several 16 volume and network plugins for Docker. 17 18 ## Types of plugins 19 20 Plugins extend Docker's functionality. They come in specific types. For 21 example, a [volume plugin](plugins_volume.md) might enable Docker 22 volumes to persist across multiple Docker hosts and a 23 [network plugin](plugins_network.md) might provide network plumbing. 24 25 Currently Docker supports volume and network driver plugins. In the future it 26 will support additional plugin types. 27 28 ## Installing a plugin 29 30 Follow the instructions in the plugin's documentation. 31 32 ## Finding a plugin 33 34 The following plugins exist: 35 36 * The [Blockbridge plugin](https://github.com/blockbridge/blockbridge-docker-volume) 37 is a volume plugin that provides access to an extensible set of 38 container-based persistent storage options. It supports single and multi-host Docker 39 environments with features that include tenant isolation, automated 40 provisioning, encryption, secure deletion, snapshots and QoS. 41 42 * The [Convoy plugin](https://github.com/rancher/convoy) is a volume plugin for a 43 variety of storage back-ends including device mapper and NFS. It's a simple standalone 44 executable written in Go and provides the framework to support vendor-specific extensions 45 such as snapshots, backups and restore. 46 47 * The [Flocker plugin](https://clusterhq.com/docker-plugin/) is a volume plugin 48 which provides multi-host portable volumes for Docker, enabling you to run 49 databases and other stateful containers and move them around across a cluster 50 of machines. 51 52 * The [GlusterFS plugin](https://github.com/calavera/docker-volume-glusterfs) is 53 another volume plugin that provides multi-host volumes management for Docker 54 using GlusterFS. 55 56 * The [IPFS Volume Plugin](http://github.com/vdemeester/docker-volume-ipfs) 57 is an open source volume plugin that allows using an 58 [ipfs](https://ipfs.io/) filesystem as a volume. 59 60 * The [Keywhiz plugin](https://github.com/calavera/docker-volume-keywhiz) is 61 a plugin that provides credentials and secret management using Keywhiz as 62 a central repository. 63 64 * The [Netshare plugin](https://github.com/gondor/docker-volume-netshare) is a volume plugin 65 that provides volume management for NFS 3/4, AWS EFS and CIFS file systems. 66 67 * The [OpenStorage Plugin](https://github.com/libopenstorage/openstorage) is a cluster aware volume plugin that provides volume management for file and block storage solutions. It implements a vendor neutral specification for implementing extensions such as CoS, encryption, and snapshots. It has example drivers based on FUSE, NFS, NBD and EBS to name a few. 68 69 * The [Quobyte Volume Plugin](https://github.com/quobyte/docker-volume) connects Docker to [Quobyte](http://www.quobyte.com/containers)'s data center file system, a general-purpose scalable and fault-tolerant storage platform. 70 71 * The [REX-Ray plugin](https://github.com/emccode/rexray) is a volume plugin 72 which is written in Go and provides advanced storage functionality for many 73 platforms including VirtualBox, EC2, Google Compute Engine, OpenStack, and EMC. 74 75 * The [Contiv Volume Plugin](https://github.com/contiv/volplugin) is an open 76 source volume plugin that provides multi-tenant, persistent, distributed storage 77 with intent based consumption using ceph underneath. 78 79 * The [Contiv Networking](https://github.com/contiv/netplugin) is an open source 80 libnetwork plugin to provide infrastructure and security policies for a 81 multi-tenant micro services deployment, while providing an integration to 82 physical network for non-container workload. Contiv Networking implements the 83 remote driver and IPAM APIs available in Docker 1.9 onwards. 84 85 * The [Weave Network Plugin](http://docs.weave.works/weave/latest_release/plugin.html) 86 creates a virtual network that connects your Docker containers - 87 across multiple hosts or clouds and enables automatic discovery of 88 applications. Weave networks are resilient, partition tolerant, 89 secure and work in partially connected networks, and other adverse 90 environments - all configured with delightful simplicity. 91 92 ## Troubleshooting a plugin 93 94 If you are having problems with Docker after loading a plugin, ask the authors 95 of the plugin for help. The Docker team may not be able to assist you. 96 97 ## Writing a plugin 98 99 If you are interested in writing a plugin for Docker, or seeing how they work 100 under the hood, see the [docker plugins reference](plugin_api.md).
