github.com/webwurst/docker@v1.7.0/experimental/plugins_volume.md (about) 1 # Experimental: Docker volume plugins 2 3 Docker volume plugins enable Docker deployments to be integrated with external 4 storage systems, such as Amazon EBS, and enable data volumes to persist beyond 5 the lifetime of a single Docker host. See the [plugin documentation](/experimental/plugins.md) 6 for more information. 7 8 This is an experimental feature. For information on installing and using experimental features, see [the experimental feature overview](README.md). 9 10 # Command-line changes 11 12 This experimental features introduces two changes to the `docker run` command: 13 14 - The `--volume-driver` flag is introduced. 15 - The `-v` syntax is changed to accept a volume name a first component. 16 17 Example: 18 19 $ docker run -ti -v volumename:/data --volume-driver=flocker busybox sh 20 21 By specifying a volume name in conjunction with a volume driver, volume plugins 22 such as [Flocker](https://clusterhq.com/docker-plugin/), once installed, can be 23 used to manage volumes external to a single host, such as those on EBS. In this 24 example, "volumename" is passed through to the volume plugin as a user-given 25 name for the volume which allows the plugin to associate it with an external 26 volume beyond the lifetime of a single container or container host. This can be 27 used, for example, to move a stateful container from one server to another. 28 29 The `volumename` must not begin with a `/`. 30 31 # API changes 32 33 The container creation endpoint (`/containers/create`) accepts a `VolumeDriver` 34 field of type `string` allowing to specify the name of the driver. It's default 35 value of `"local"` (the default driver for local volumes). 36 37 # Related GitHub PRs and issues 38 39 - [#13161](https://github.com/docker/docker/pull/13161) Volume refactor and external volume plugins 40 41 Send us feedback and comments on [#13420](https://github.com/docker/docker/issues/13420), 42 or on the usual Google Groups (docker-user, docker-dev) and IRC channels.
