     4  # NAME
     5  docker-images - List images
     6  
     7  # SYNOPSIS
     8  **docker images**
     9  [**--help**]
    10  [**-a**|**--all**]
    11  [**--digests**]
    12  [**-f**|**--filter**[=*[]*]]
    13  [**--format**=*"TEMPLATE"*]
    14  [**--no-trunc**]
    15  [**-q**|**--quiet**]
    16  [REPOSITORY[:TAG]]
    17  
    18  # DESCRIPTION
    19  This command lists the images stored in the local Docker repository.
    20  
    21  By default, intermediate images, used during builds, are not listed. Some of the
    22  output, e.g., image ID, is truncated, for space reasons. However the truncated
    23  image ID, and often the first few characters, are enough to be used in other
    24  Docker commands that use the image ID. The output includes repository, tag, image
    25  ID, date created and the virtual size.
    26  
    27  The title REPOSITORY for the first title may seem confusing. It is essentially
    28  the image name. However, because you can tag a specific image, and multiple tags
    29  (image instances) can be associated with a single name, the name is really a
    30  repository for all tagged images of the same name. For example consider an image
    31  called fedora. It may be tagged with 18, 19, or 20, etc. to manage different
    32  versions.
    33  
    34  # OPTIONS
    35  **-a**, **--all**=*true*|*false*
    36     Show all images (by default filter out the intermediate image layers). The default is *false*.
    37  
    38  **--digests**=*true*|*false*
    39     Show image digests. The default is *false*.
    40  
    41  **-f**, **--filter**=[]
    42     Filters the output based on these conditions:
    43     - dangling=(true|false) - find unused images
    44     - label=<key> or label=<key>=<value>
    45     - before=(<image-name>[:tag]|<image-id>|<image@digest>)
    46     - since=(<image-name>[:tag]|<image-id>|<image@digest>)
    47  
    48  **--format**="*TEMPLATE*"
    49     Pretty-print images using a Go template.
    50     Valid placeholders:
    51        .ID - Image ID
    52        .Repository - Image repository
    53        .Tag - Image tag
    54        .Digest - Image digest
    55        .CreatedSince - Elapsed time since the image was created
    56        .CreatedAt - Time when the image was created
    57        .Size - Image disk size
    58  
    59  **--help**
    60    Print usage statement
    61  
    62  **--no-trunc**=*true*|*false*
    63     Don't truncate output. The default is *false*.
    64  
    65  **-q**, **--quiet**=*true*|*false*
    66     Only show numeric IDs. The default is *false*.
    67  
    68  # EXAMPLES
    69  
    70  ## Listing the images
    71  
    72  To list the images in a local repository (not the registry) run:
    73  
    74      docker images
    75  
    76  The list will contain the image repository name, a tag for the image, and an
    77  image ID, when it was created and its virtual size. Columns: REPOSITORY, TAG,
    78  IMAGE ID, CREATED, and SIZE.
    79  
    80  The `docker images` command takes an optional `[REPOSITORY[:TAG]]` argument
    81  that restricts the list to images that match the argument. If you specify
    82  `REPOSITORY`but no `TAG`, the `docker images` command lists all images in the
    83  given repository.
    84  
    85      docker images java
    86  
    87  The `[REPOSITORY[:TAG]]` value must be an "exact match". This means that, for example,
    88  `docker images jav` does not match the image `java`.
    89  
    90  If both `REPOSITORY` and `TAG` are provided, only images matching that
    91  repository and tag are listed.  To find all local images in the "java"
    92  repository with tag "8" you can use:
    93  
    94      docker images java:8
    95  
    96  To get a verbose list of images which contains all the intermediate images
    97  used in builds use **-a**:
    98  
    99      docker images -a
   100  
   101  Previously, the docker images command supported the --tree and --dot arguments,
   102  which displayed different visualizations of the image data. Docker core removed
   103  this functionality in the 1.7 version. If you liked this functionality, you can
   104  still find it in the third-party dockviz tool: https://github.com/justone/dockviz.
   105  
   106  ## Listing images in a desired format
   107  
   108  When using the --format option, the image command will either output the data 
   109  exactly as the template declares or, when using the `table` directive, will 
   110  include column headers as well. You can use special characters like `\t` for
   111  inserting tab spacing between columns. 
   112  
   113  The following example uses a template without headers and outputs the ID and 
   114  Repository entries separated by a colon for all images:
   115  
   116      docker images --format "{{.ID}}: {{.Repository}}"
   117      77af4d6b9913: <none>
   118      b6fa739cedf5: committ
   119      78a85c484bad: ipbabble
   120      30557a29d5ab: docker
   121      5ed6274db6ce: <none>
   122      746b819f315e: postgres
   123      746b819f315e: postgres
   124      746b819f315e: postgres
   125      746b819f315e: postgres
   126  
   127  To list all images with their repository and tag in a table format you can use:
   128  
   129      docker images --format "table {{.ID}}\t{{.Repository}}\t{{.Tag}}"
   130      IMAGE ID            REPOSITORY                TAG
   131      77af4d6b9913        <none>                    <none>
   132      b6fa739cedf5        committ                   latest
   133      78a85c484bad        ipbabble                  <none>
   134      30557a29d5ab        docker                    latest
   135      5ed6274db6ce        <none>                    <none>
   136      746b819f315e        postgres                  9
   137      746b819f315e        postgres                  9.3
   138      746b819f315e        postgres                  9.3.5
   139      746b819f315e        postgres                  latest
   140  
   141  Valid template placeholders are listed above.

   143  ## Listing only the shortened image IDs
   144  
   145  Listing just the shortened image IDs. This can be useful for some automated
   146  tools.
