# DESCRIPTION
|
|
|
|
This displays all the information available in Docker for a given
|
|
container or image. 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.
|
|
|
|
# OPTIONS
|
|
**--help**
|

|
|
|
|
**-s**, **--size**

## 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
|
|
[{
