[
{
 "Id": "fe01a428b9d9de35d29531e9994157978e8c48fa693e1bf1d221dffbbb67b170",
 "Parent": "10acc31def5d6f249b548e01e8ffbaccfd61af0240c17315a7ad393d022c5ca2",
 ....
}
]

Getting information on a container

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

$ docker inspect d2cc496561d6

] ### 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
