docker-inspect - Return low-level information on Docker objects
docker inspect [OPTIONS] NAME|ID [NAME|ID...]
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.
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

To get information on a container use its ID or instance name:
$ docker inspect d2cc496561d6

To get the IP address of a container use:
$ docker inspect --format='{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' d2cc496561d6
172.17.0.2
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/.
$ docker inspect -s d2cc496561d6

Use an image's ID or name (e.g., repository/name[:tag]) to get information about the image:
$ docker inspect ded7cd95e059
