## Description
|
|
|
|
List all the volumes known to Docker. You can filter using the `-f` or
|
|
`--filter` flag. Refer to the [filtering](#filter) section for more
|
|
information about available filter options.
|
|
|
|
## Examples
|
|
|
|
### Create a volume
|
|
|
|
```console
|
|
$ docker volume create rosemary
|
|
|
|
rosemary
|
|
|
|
$ docker volume create tyler
|
|
|
|
tyler
|
|
|
|
$ docker volume ls
|
|
|
|
DRIVER VOLUME NAME
|
|
local rosemary
|
|
local tyler
|
|
```
|
|
|
|
### <a name="filter"></a> Filtering (--filter)
|
|
|
|
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
|
|
|
|
```console
|
|
$ docker run -d -v tyler:/tmpwork busybox
|
|
|
|
f86a7dd02898067079c99ceacd810149060a70528eff3754d0b0f1a93bd0af18
|
|
$ docker volume ls -f dangling=true
|
|
DRIVER VOLUME NAME
|
|
local rosemary
|
|
```
|
|
|
|
#### driver
|
|
|
|
The `driver` filter matches volumes based on their driver.
|
|
|
|
The following example matches volumes that are created with the `local` driver:
|
|
|
|
```console
|
|
$ 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;
|
|
|
|
```console
|
|
$ 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.
|
|
|
|
```console
|
|
$ docker volume ls --filter label=is-timelord
|
|
|
|
DRIVER VOLUME NAME
|
|
local daleks
|
|
local the-doctor
|
|
```
|
|
|
|
As the above example demonstrates, 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:
|
|
|
|
```console
|
|
$ docker volume ls --filter label=is-timelord=yes
|
|
|
|
DRIVER VOLUME NAME
|
|
local the-doctor
|
|
```
|
|
|
|
Specifying multiple label filter produces an "and" search; all conditions
|
|
should be met;
|
|
|
|
```console
|
|
$ docker volume ls --filter label=is-timelord=yes --filter label=is-timelord=no
|
|
|
|
DRIVER VOLUME 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.
|
|
|
|
```console
|
|
$ docker volume ls -f name=rose
|
|
|
|
DRIVER VOLUME NAME
|
|
local rosemary
|
|
```
|
|
|
|
### <a name="format"></a> Format the output (--format)
|
|
|
|
The formatting options (`--format`) pretty-prints volumes output
|
|
using a Go template.
|
|
|
|
Valid placeholders for the Go template are listed below:
|
|
|
|
| Placeholder | Description |
|
|
|---------------|---------------------------------------------------------------------------------------|
|
|
| `.Name` | Volume name |
|
|
| `.Driver` | Volume driver |
|
|
| `.Scope` | Volume scope (local, global) |
|
|
| `.Mountpoint` | The mount point of the volume on the host |
|
|
| `.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:
|
|
|
|
```console
|
|
$ docker volume ls --format "{{.Name}}: {{.Driver}}"
|
|
|
|
vol1: local
|
|
vol2: local
|
|
vol3: local
|
|
```
|
|
|
|
To list all volumes in JSON format, use the `json` directive:
|
|
|
|
```console
|
|
$ docker volume ls --format json
|
|
{"Driver":"local","Labels":"","Links":"N/A","Mountpoint":"/var/lib/docker/volumes/docker-cli-dev-cache/_data","Name":"docker-cli-dev-cache","Scope":"local","Size":"N/A"}
|
|
```
