NAME
       docker-image-ls - List images

SYNOPSIS
       docker image ls [OPTIONS] [REPOSITORY[:TAG]]

DESCRIPTION
       This command lists the images stored in the local Docker repository.

       By default, intermediate images, used during builds, are not listed. Some of the output, e.g.,
       image ID, is truncated, for space reasons. However the truncated image ID, and often the first
       few characters, are enough to be used in other Docker commands that use the image ID. The
       output includes repository, tag, image ID, date created and the virtual size.

       The title REPOSITORY for the first title may seem confusing. It is essentially the image name.
       However, because you can tag a specific image, and multiple tags (image instances) can be
       associated with a single name, the name is really a repository for all tagged images of the
       same name. For example consider an image called fedora. It may be tagged with 18, 19, or 20,
       etc. to manage different versions.

Filters
       Filters the output based on these conditions:

	      · dangling=(true|false) - find unused images

	      · label=<key> or label=<key>=<value>

	      · before=(<image-name>[:tag]|<image-id>| ⟨image@digest⟩)

	      · since=(<image-name>[:tag]|<image-id>| ⟨image@digest⟩)

	      · reference=(pattern of an image reference)

Format
       Pretty-print images using a Go template.
	  Valid placeholders:
	     .ID - Image ID
	     .Repository - Image repository
	     .Tag - Image tag
	     .Digest - Image digest
	     .CreatedSince - Elapsed time since the image was created
	     .CreatedAt - Time when the image was created
	     .Size - Image disk size

EXAMPLES
Listing the images
       To list the images in a local repository (not the registry) run:

	      docker image ls

       The list will contain the image repository name, a tag for the image, and an image ID, when it
       was created and its virtual size. Columns: REPOSITORY, TAG, IMAGE ID, CREATED, and SIZE.

       The docker image ls command takes an optional [REPOSITORY[:TAG]] argument that restricts the
       list to images that match the argument. If you specify REPOSITORY but no TAG, the docker image
       ls command lists all images in the given repository.

	      docker image ls java

       The [REPOSITORY[:TAG]] value must be an "exact match". This means that, for example, docker
       image ls jav does not match the image java.

       If both REPOSITORY and TAG are provided, only images matching that repository and tag are
       listed.	To find all local images in the "java" repository with tag "8" you can use:

	      docker image ls java:8

       To get a verbose list of images which contains all the intermediate images used in builds use
       -a:

	      docker image ls -a

       Previously, the docker image ls command supported the --tree and --dot arguments, which
       displayed different visualizations of the image data. Docker core removed this functionality in
       the 1.7 version. If you liked this functionality, you can still find it in the third-party
       dockviz tool: ⟨https://github.com/justone/dockviz⟩.

Listing images in a desired format
       When using the --format option, the image command will either output the data exactly as the
       template declares or, when using the table directive, will include column headers as well. You
       can use special characters like \t for inserting tab spacing between columns.

       The following example uses a template without headers and outputs the ID and Repository entries
       separated by a colon for all images:

	      docker images --format "{{.ID}}: {{.Repository}}"
	      77af4d6b9913: <none>
	      b6fa739cedf5: committ
	      78a85c484bad: ipbabble
	      30557a29d5ab: docker
	      5ed6274db6ce: <none>
	      746b819f315e: postgres
	      746b819f315e: postgres
	      746b819f315e: postgres
	      746b819f315e: postgres

       To list all images with their repository and tag in a table format you can use:

	      docker images --format "table {{.ID}}\t{{.Repository}}\t{{.Tag}}"
	      IMAGE ID		  REPOSITORY		    TAG
	      77af4d6b9913	  <none>		    <none>
	      b6fa739cedf5	  committ		    latest
	      78a85c484bad	  ipbabble		    <none>
	      30557a29d5ab	  docker		    latest
	      5ed6274db6ce	  <none>		    <none>
	      746b819f315e	  postgres		    9
	      746b819f315e	  postgres		    9.3
	      746b819f315e	  postgres		    9.3.5
	      746b819f315e	  postgres		    latest

       Valid template placeholders are listed above.

Listing only the shortened image IDs
       Listing just the shortened image IDs. This can be useful for some automated tools.

	      docker image ls -q

OPTIONS
       -a, --all[=false]
	   Show all images (default hides intermediate images)

       --digests[=false]
	   Show digests

       -f, --filter=
	   Filter output based on conditions provided

       --format=""

       -h, --help[=false]
	   help for ls

       --no-trunc[=false]

       -q, --quiet[=false]
