# volume ls
|
|
|
|
```markdown
|
|
Usage: docker volume ls [OPTIONS]
|
|
|
|
List volumes
|
|
|
|
Aliases:
|
|
ls, list
|
|
|
|
Options:
|
|
-f, --filter value Provide filter values (e.g. 'dangling=true') (default [])
|
|
- dangling=<boolean> a volume if referenced or not
|
|
- driver=<string> a volume's driver name
|
|
- label=<key> or label=<key>=<value>
|
|
- name=<string> a volume's name
|
|
--format string Pretty-print volumes using a Go template
|
|
--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. Refer to the [filtering](#filtering) section for more information about available filter options.
|
|
|
|
Example output:
|
|
|
|
```bash
|
|
$ docker volume create rosemary
|
|
rosemary
|
|
$docker volume create tyler
|
|
tyler
|
|
$ docker volume ls
|
|
DRIVER VOLUME NAME
|
|
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)
|
|
* label (`label=<key>` or `label=<key>=<value>`)
|
|
* name (a volume's name)
|
|
|
|
### dangling
|
|
|
|
The `dangling` filter matches on all volumes not referenced by any containers
|
|
|
|
```bash
|
|
$ docker run -d -v tyler:/tmpwork busybox
|
|
|
|
f86a7dd02898067079c99ceacd810149060a70528eff3754d0b0f1a93bd0af18
|
|
$ 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.
|
|
|
|
```bash
|
|
$ docker volume ls -f driver=local
|
|
|
|
DRIVER VOLUME NAME
|
|
local rosemary
|
|
local tyler
|
|
```
|
|
|
|
#### Label
|
|
|
|
The `label` filter matches volumes based on the presence of a `label` alone or
|
|
a `label` and a value.
|
|
|
|
First, let's create some volumes to illustrate this;
|
|
|
|
```bash
|
|
$ docker volume create the-doctor --label is-timelord=yes
|
|
the-doctor
|
|
$ docker volume create daleks --label is-timelord=no
|
|
daleks
|
|
```
|
|
|
|
The following example filter matches volumes with the `is-timelord` label
|
|
regardless of its value.
|
|
|
|
```bash
|
|
$ docker volume ls --filter label=is-timelord
|
|
|
|
DRIVER NAME
|
|
local daleks
|
|
local the-doctor
|
|
```
|
|
|
|
As can be seen in the above example, both volumes with `is-timelord=yes`, and
|
|
`is-timelord=no` are returned.
|
|
|
|
Filtering on both `key` *and* `value` of the label, produces the expected result:
|
|
|
|
```bash
|
|
$ docker volume ls --filter label=is-timelord=yes
|
|
|
|
DRIVER NAME
|
|
local the-doctor
|
|
```
|
|
|
|
Specifying multiple label filter produces an "and" search; all conditions
|
|
should be met;
|
|
|
|
```bash
|
|
$ docker volume ls --filter label=is-timelord=yes --filter label=is-timelord=no
|
|
|
|
DRIVER NAME
|
|
```
|
|
|
|
### 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.
|
|
|
|
$ docker volume ls -f name=rose
|
|
DRIVER VOLUME NAME
|
|
local rosemary
|
|
|
|
## Formatting
|
|
|
|
The formatting options (`--format`) pretty-prints volumes output
|
|
using a Go template.
|
|
|
|
Valid placeholders for the Go template are listed below:
|
|
|
|
Placeholder | Description
|
|
--------------|------------------------------------------------------------------------------------------
|
|
`.Name` | Network name
|
|
`.Driver` | Network driver
|
|
`.Scope` | Network scope (local, global)
|
|
`.Mountpoint` | Whether the network is internal or not.
|
|
`.Labels` | All labels assigned to the volume.
|
|
`.Label` | Value of a specific label for this volume. For example `{{.Label "project.version"}}`
|
|
|
|
When using the `--format` option, the `volume ls` command will either
|
|
output the data exactly as the template declares or, when using the
|
|
`table` directive, includes column headers as well.
|
|
|
|
The following example uses a template without headers and outputs the
|
|
`Name` and `Driver` entries separated by a colon for all volumes:
|
|
|
|
```bash
|
|
$ docker volume ls --format "{{.Name}}: {{.Driver}}"
|
|
vol1: local
|
|
vol2: local
|
|
vol3: local
|
|
```
|
|
