volume ls

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 section for more information about available filter options.

Example output:

$ 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

$ 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.

$ 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;

$ 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.

$ 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:

$ 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;

$ 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:

$ docker volume ls --format "{{.Name}}: {{.Driver}}"
vol1: local
vol2: local
vol3: local
