The plugin must be disabled. The settings currently supported are: * env variables * source of mounts * path of devices * args ## What is settable ? Look at the plugin manifest, it's easy to see what fields are settable, by looking at the `Settable` field. Here is an extract of a plugin manifest: ``` { "config": { ... "args": { "name": "myargs", "settable": ["value"], "value": ["foo", "bar"] }, "env": [ { "name": "DEBUG", "settable": ["value"], "value": "0" }, { "name": "LOGGING", "value": "1" } ], "devices": [ { "name": "mydevice", "path": "/dev/foo", "settable": ["path"] } ], "mounts": [ { "destination": "/baz", "name": "mymount", "options": ["rbind"], "settable": ["source"], "source": "/foo", "type": "bind" } ], ... } } ``` In this example, we can see that the `value` of the `DEBUG` environment variable is settable, the `source` of the `mymount` mount is also settable. Same for the `path` of `mydevice` and `value` of `myargs`. On the contrary, the `LOGGING` environment variable doesn't have any settable field, which implies that user cannot tweak it. ## Examples ### Change an environment variable The following example change the env variable `DEBUG` on the `sample-volume-plugin` plugin. ```bash $ docker plugin inspect -f {{.Settings.Env}} tiborvass/sample-volume-plugin [DEBUG=0] $ docker plugin set tiborvass/sample-volume-plugin DEBUG=1 $ docker plugin inspect -f {{.Settings.Env}} tiborvass/sample-volume-plugin [DEBUG=1] ``` ### Change the source of a mount The following example change the source of the `mymount` mount on the `myplugin` plugin. ```bash $ docker plugin inspect -f '{{with $mount := index .Settings.Mounts 0}}{{$mount.Source}}{{end}}' myplugin /foo $ docker plugins set myplugin mymount.source=/bar $ docker plugin inspect -f '{{with $mount := index .Settings.Mounts 0}}{{$mount.Source}}{{end}}' myplugin /bar ``` > **Note**: Since only `source` is settable in `mymount`, > `docker plugins set mymount=/bar myplugin` would work too. ### Change a device path The following example change the path of the `mydevice` device on the `myplugin` plugin. ```bash $ docker plugin inspect -f '{{with $device := index .Settings.Devices 0}}{{$device.Path}}{{end}}' myplugin /dev/foo $ docker plugins set myplugin mydevice.path=/dev/bar $ docker plugin inspect -f '{{with $device := index .Settings.Devices 0}}{{$device.Path}}{{end}}' myplugin /dev/bar ``` > **Note**: Since only `path` is settable in `mydevice`, > `docker plugins set mydevice=/dev/bar myplugin` would work too. ### Change the source of the arguments The following example change the value of the args on the `myplugin` plugin. ```bash $ docker plugin inspect -f '{{.Settings.Args}}' myplugin ["foo", "bar"] $ docker plugins set myplugin myargs="foo bar baz" $ docker plugin inspect -f '{{.Settings.Args}}' myplugin ["foo", "bar", "baz"] ``` ## Related commands * [plugin create](plugin_create.md) * [plugin disable](plugin_disable.md) * [plugin enable](plugin_enable.md) * [plugin inspect](plugin_inspect.md) * [plugin install](plugin_install.md) * [plugin ls](plugin_ls.md) * [plugin push](plugin_push.md) * [plugin rm](plugin_rm.md) * [plugin upgrade](plugin_upgrade.md)
