     4  # NAME
     5  docker-images - List images
     6  
     7  # SYNOPSIS
     8  **docker images**
     9  [**--help**]
    10  [**-a**|**--all**]
    11  [**--digests**]
    12  [**-f**|**--filter**[=*[]*]]
    13  [**--no-trunc**]
    14  [**-q**|**--quiet**]
    15  [REPOSITORY[:TAG]]
    16  
    17  # DESCRIPTION
    18  This command lists the images stored in the local Docker repository.
    19  
    20  By default, intermediate images, used during builds, are not listed. Some of the
    21  output, e.g., image ID, is truncated, for space reasons. However the truncated
    22  image ID, and often the first few characters, are enough to be used in other
    23  Docker commands that use the image ID. The output includes repository, tag, image
    24  ID, date created and the virtual size.
    25  
    26  The title REPOSITORY for the first title may seem confusing. It is essentially
    27  the image name. However, because you can tag a specific image, and multiple tags
    28  (image instances) can be associated with a single name, the name is really a
    29  repository for all tagged images of the same name. For example consider an image
    30  called fedora. It may be tagged with 18, 19, or 20, etc. to manage different
    31  versions.
    32  
    33  # OPTIONS
    34  **-a**, **--all**=*true*|*false*
    35     Show all images (by default filter out the intermediate image layers). The default is *false*.
    36  
    37  **--digests**=*true*|*false*
    38     Show image digests. The default is *false*.
    39  
    40  **-f**, **--filter**=[]
    41     Filters the output based on these conditions:
    42     - dangling=(true|false) - finds unused images.
    43     - label=<key> or label=<key>=<value>
    44     - before=(<image-name>[:tag]|<image-id>|<image@digest>)
    45     - since=(<image-name>[:tag]|<image-id>|<image@digest>)
    46  
    47  **--format**="*TEMPLATE*"
    48     Pretty-print containers using a Go template.
    49     Valid placeholders:
    50        .ID - Image ID
    51        .Repository - Image repository
    52        .Tag - Image tag
    53        .Digest - Image digest
    54        .CreatedSince - Elapsed time since the image was created.
    55        .CreatedAt - Time when the image was created..
    56        .Size - Image disk size.
    57  
    58  **--help**
    59    Print usage statement
    60  
    61  **--no-trunc**=*true*|*false*
    62     Don't truncate output. The default is *false*.
    63  
    64  **-q**, **--quiet**=*true*|*false*
    65     Only show numeric IDs. The default is *false*.
    66  
    67  # EXAMPLES
    68  
    69  ## Listing the images
    70  
    71  To list the images in a local repository (not the registry) run:
    72  
    73      docker images
    74  
    75  The list will contain the image repository name, a tag for the image, and an
    76  image ID, when it was created and its virtual size. Columns: REPOSITORY, TAG,
    77  IMAGE ID, CREATED, and SIZE.
    78  
    79  The `docker images` command takes an optional `[REPOSITORY[:TAG]]` argument
    80  that restricts the list to images that match the argument. If you specify
    81  `REPOSITORY`but no `TAG`, the `docker images` command lists all images in the
    82  given repository.
    83  
    84      docker images java
    85  
    86  The `[REPOSITORY[:TAG]]` value must be an "exact match". This means that, for example,
    87  `docker images jav` does not match the image `java`.
    88  
    89  If both `REPOSITORY` and `TAG` are provided, only images matching that
    90  repository and tag are listed.  To find all local images in the "java"
    91  repository with tag "8" you can use:
    92  
    93      docker images java:8
    94  
    95  To get a verbose list of images which contains all the intermediate images
    96  used in builds use **-a**:
    97  
    98      docker images -a
    99  
   100  Previously, the docker images command supported the --tree and --dot arguments,
   101  which displayed different visualizations of the image data. Docker core removed
   102  this functionality in the 1.7 version. If you liked this functionality, you can
   103  still find it in the third-party dockviz tool: https://github.com/justone/dockviz.
   104  
   105  ## Listing only the shortened image IDs
   106  
   107  Listing just the shortened image IDs. This can be useful for some automated
   108  tools.
   109  
   110      docker images -q
