     4  # NAME
     5  docker-inspect - Return low-level information on docker objects
     6  
     7  # SYNOPSIS
     8  **docker inspect**
     9  [**--help**]
    10  [**-f**|**--format**[=*FORMAT*]]
    11  [**-s**|**--size**]
    12  [**--type**=*container*|*image*|*network*|*node*|*service*|*task*|*volume*]
    13  NAME|ID [NAME|ID...]
    14  
    15  # DESCRIPTION
    16  
    17  This displays the low-level information on Docker object(s) (e.g. container, 
    18  image, volume,network, node, service, or task) identified by name or ID. By default,
    19  this will render all results in a JSON array. If the container and image have
    20  the same name, this will return container JSON for unspecified type. If a format
    21  is specified, the given template will be executed for each result.
    22  
    23  # OPTIONS
    24  **--help**
    25      Print usage statement
    26  
    27  **-f**, **--format**=""
    28      Format the output using the given Go template
    29  
    30  **-s**, **--size**
    31      Display total file sizes if the type is container
    32  
    33  **--type**=*container*|*image*|*network*|*node*|*service*|*task*|*volume*
    34      Return JSON for specified type, permissible values are "image", "container",
    35      "network", "node", "service", "task", and "volume"
    36  
    37  # EXAMPLES
    38  
    39  Get information about an image when image name conflicts with the container name,
    40  e.g. both image and container are named rhel7:
    41  
    42      $ docker inspect --type=image rhel7
    43      [
    44      {
    45       "Id": "fe01a428b9d9de35d29531e9994157978e8c48fa693e1bf1d221dffbbb67b170",

    47       ....
    48      }
    49      ]
    50  
    51  ## Getting information on a container
    52  
    53  To get information on a container use its ID or instance name:
    54  
    55      $ docker inspect d2cc496561d6
    56      [{

   208  ## Getting the IP address of a container instance
   209  
   210  To get the IP address of a container use:
   211  
   212      $ docker inspect --format='{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' d2cc496561d6
   213      172.17.0.2
   214  
   215  ## Listing all port bindings
   216  
   217  One can loop over arrays and maps in the results to produce simple text
   218  output:
   219  
   220      $ docker inspect --format='{{range $p, $conf := .NetworkSettings.Ports}} \
   221        {{$p}} -> {{(index $conf 0).HostPort}} {{end}}' d2cc496561d6
   222        80/tcp -> 80
   223  
   224  You can get more information about how to write a Go template from:
   225  https://golang.org/pkg/text/template/.
   226  
   227  ## Getting size information on a container
   228  
   229      $ docker inspect -s d2cc496561d6
   230      [
   231      {
   232      ....
   233      "SizeRw": 0,
   234      "SizeRootFs": 972,
   235      ....
   236      }
   237      ]
   238  
   239  ## Getting information on an image
   240  
   241  Use an image's ID or name (e.g., repository/name[:tag]) to get information
   242  about the image:
   243  
   244      $ docker inspect ded7cd95e059
   245      [{
   246      "Id": "ded7cd95e059788f2586a51c275a4f151653779d6a7f4dad77c2bd34601d94e4",
