List volumes
|
||||
|
||||
-f, --filter=[] Provide filter values (i.e. 'dangling=true')
|
||||
-f, --filter=[] Filter output based on these conditions:
|
||||
- dangling=<boolean> a volume if referenced or not
|
||||
- driver=<string> a volume's driver name
|
||||
- name=<string> a volume's name
|
||||
--help Print usage
|
||||
-q, --quiet Only display volume names
|
||||
|
||||
Lists all the volumes Docker knows about. You can filter using the `-f` or `--filter` flag. The filtering format is a `key=value` pair. To specify more than one filter, pass multiple flags (for example, `--filter "foo=bar" --filter "bif=baz"`)
|
||||
|
||||
There is a single supported filter `dangling=value` which takes a boolean of `true` or `false`.
|
||||
Lists all the volumes Docker knows about. You can filter using the `-f` or `--filter` flag. Refer to the [filtering](#filtering) section for more information about available filter options.

Example output:
|
||||
|
||||
$ docker volume create --name rose
|
||||
rose
|
||||
$ docker volume create --name rosemary
|
||||
rosemary
|
||||
$docker volume create --name tyler
|
||||
tyler
|
||||
$ docker volume ls
|
||||
DRIVER VOLUME NAME
|
||||
local rose
|
||||
local rosemary
|
||||
local tyler
|
||||
|
||||
## Filtering
|
||||
|
||||
The filtering flag (`-f` or `--filter`) format is of "key=value". If there is more
|
||||
than one filter, then pass multiple flags (e.g., `--filter "foo=bar" --filter "bif=baz"`)
|
||||
|
||||
The currently supported filters are:
|
||||
|
||||
* dangling (boolean - true or false, 0 or 1)
|
||||
* driver (a volume driver's name)
|
||||
* name (a volume's name)
|
||||
|
||||
### dangling
|
||||
|
||||
The `dangling` filter matches on all volumes not referenced by any containers
|
||||
|
||||
$ docker run -d -v tyler:/tmpwork busybox
|
||||

|
||||
$ docker volume ls -f dangling=true
|
||||
DRIVER VOLUME NAME
|
||||
local rosemary
|
||||
|
||||
### driver
|
||||
|
||||
The `driver` filter matches on all or part of a volume's driver name.
|
||||
|
||||
The following filter matches all volumes with a driver name containing the `local` string.
|
||||
|
||||
$ docker volume ls -f driver=local
|
||||
DRIVER VOLUME NAME
|
||||
local rosemary
|
||||
local tyler
|
||||
|
||||
### name
|
||||
|
||||
The `name` filter matches on all or part of a volume's name.
|
||||
|
||||
The following filter matches all volumes with a name containing the `rose` string.
|

|
||||
DRIVER VOLUME NAME
