     1  This command lists the images stored in the local Docker repository.
     2  
     3  By default, intermediate images, used during builds, are not listed. Some of the
     4  output, e.g., image ID, is truncated, for space reasons. However the truncated
     5  image ID, and often the first few characters, are enough to be used in other
     6  Docker commands that use the image ID. The output includes repository, tag, image
     7  ID, date created and the virtual size.
     8  
     9  The title REPOSITORY for the first title may seem confusing. It is essentially
    10  the image name. However, because you can tag a specific image, and multiple tags
    11  (image instances) can be associated with a single name, the name is really a
    12  repository for all tagged images of the same name. For example consider an image
    13  called ubuntu. It may be tagged with 20.04 or 22.04, etc. to manage different
    14  versions.
    15  
    16  ## Filters
    17  
    18  Filters the output based on these conditions:
    19  
    20     - dangling=(true|false) - find unused images
    21     - label=<key> or label=<key>=<value>
    22     - before=(<image-name>[:tag]|<image-id>|<image@digest>)
    23     - since=(<image-name>[:tag]|<image-id>|<image@digest>)
    24     - reference=(pattern of an image reference)
    25  
    26  ## Format
    27  
    28     Pretty-print images using a Go template.
    29     Valid placeholders:
    30        .ID - Image ID
    31        .Repository - Image repository
    32        .Tag - Image tag
    33        .Digest - Image digest
    34        .CreatedSince - Elapsed time since the image was created
    35        .CreatedAt - Time when the image was created
    36        .Size - Image disk size
    37  
    38  # EXAMPLES
    39  
    40  ## Listing the images
    41  
    42  To list the images in a local repository (not the registry) run:
    43  
    44      docker image ls
    45  
    46  The list will contain the image repository name, a tag for the image, and an
    47  image ID, when it was created and its virtual size. Columns: REPOSITORY, TAG,
    48  IMAGE ID, CREATED, and SIZE.
    49  
    50  The `docker image ls` command takes an optional `[REPOSITORY[:TAG]]` argument
    51  that restricts the list to images that match the argument. If you specify
    52  `REPOSITORY` but no `TAG`, the `docker image ls` command lists all images in the
    53  given repository.
    54  
    55      docker image ls java
    56  
    57  The `[REPOSITORY[:TAG]]` value must be an "exact match". This means that, for example,
    58  `docker image ls jav` does not match the image `java`.
    59  
    60  If both `REPOSITORY` and `TAG` are provided, only images matching that
    61  repository and tag are listed.  To find all local images in the "java"
    62  repository with tag "8" you can use:
    63  
    64      docker image ls java:8
    65  
    66  To get a verbose list of images which contains all the intermediate images
    67  used in builds use **-a**:
    68  
    69      docker image ls -a
    70  
    71  Previously, the docker image ls command supported the --tree and --dot arguments,
    72  which displayed different visualizations of the image data. Docker core removed
    73  this functionality in the 1.7 version. If you liked this functionality, you can
    74  still find it in the third-party dockviz tool: https://github.com/justone/dockviz.
    75  
    76  ## Listing images in a desired format
    77  
    78  When using the --format option, the image command will either output the data 
    79  exactly as the template declares or, when using the `table` directive, will 
    80  include column headers as well. You can use special characters like `\t` for
    81  inserting tab spacing between columns. 
    82  
    83  The following example uses a template without headers and outputs the ID and 
    84  Repository entries separated by a colon for all images:
    85  
    86      docker images --format "{{.ID}}: {{.Repository}}"
    87      77af4d6b9913: <none>
    88      b6fa739cedf5: committ
    89      78a85c484bad: ipbabble
    90      30557a29d5ab: docker
    91      5ed6274db6ce: <none>
    92      746b819f315e: postgres
    93      746b819f315e: postgres
    94      746b819f315e: postgres
    95      746b819f315e: postgres
    96  
    97  To list all images with their repository and tag in a table format you can use:
    98  
    99      docker images --format "table {{.ID}}\t{{.Repository}}\t{{.Tag}}"
   100      IMAGE ID            REPOSITORY                TAG
   101      77af4d6b9913        <none>                    <none>
   102      b6fa739cedf5        committ                   latest
   103      78a85c484bad        ipbabble                  <none>
   104      30557a29d5ab        docker                    latest
   105      5ed6274db6ce        <none>                    <none>
   106      746b819f315e        postgres                  9
   107      746b819f315e        postgres                  9.3
   108      746b819f315e        postgres                  9.3.5
   109      746b819f315e        postgres                  latest
   110
