DOCKER(1)                                                            DOCKER(1)

NAME
       docker-inspect - Return low-level information on Docker objects

SYNOPSIS
       docker inspect [OPTIONS] NAME|ID [NAME|ID...]

DESCRIPTION
       This displays the low-level information on Docker object(s) (e.g.
       container, image, volume,network, node, service, or task) identified by
       name or ID. By default, this will render all results in a JSON array.
       If the container and image have the same name, this will return
       container JSON for unspecified type. If a format is specified, the
       given template will be executed for each result.

EXAMPLES
       Get information about an image when image name conflicts with the
       container name, e.g. both image and container are named rhel7:

              $ docker inspect --type=image rhel7
              [
              {
               "Id": "fe01a428b9d9de35d29531e9994157978e8c48fa693e1bf1d221dffbbb67b170",
               "Parent": "10acc31def5d6f249b548e01e8ffbaccfd61af0240c17315a7ad393d022c5ca2",
               ....
              }
              ]

Getting information on a container
       To get information on a container use its ID or instance name:

              $ docker inspect d2cc496561d6
              [{
              "Id": "d2cc496561d6d520cbc0236b4ba88c362c446a7619992123f11c809cded25b47",

Getting the IP address of a container instance
       To get the IP address of a container use:

              $ docker inspect --format='{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' d2cc496561d6
              172.17.0.2

Listing all port bindings
       One can loop over arrays and maps in the results to produce simple text
       output:

              $ docker inspect --format='{{range $p, $conf := .NetworkSettings.Ports}} \
                {{$p}} -> {{(index $conf 0).HostPort}} {{end}}' d2cc496561d6
                80/tcp -> 80

       You can get more information about how to write a Go template from:

       <https://golang.org/pkg/text/template/>.

Getting size information on a container
              $ docker inspect -s d2cc496561d6
              [
              {
              "SizeRw": 0,
              "SizeRootFs": 972,
              }
              ]

Getting information on an image
       Use an image's ID or name (e.g., repository/name[:tag]) to get
       information about the image:

              $ docker inspect ded7cd95e059
              [{
              "Id": "ded7cd95e059788f2586a51c275a4f151653779d6a7f4dad77c2bd34601d94e4",
