David Calavera 3b5fac462d Remove LXC support.

The LXC driver was deprecated in Docker 1.8.
Following the deprecation rules, we can remove a deprecated feature
after two major releases. LXC won't be supported anymore starting on Docker 1.10.

NAME

docker-inspect - Return low-level information on a container or image

SYNOPSIS

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 a format is specified, the given template will be executed for each result.

OPTIONS

--help Print usage statement

-f, --format="" Format the output using the given Go template.

-s, --size=false Display total file sizes if the type is container.

--type=container|image Return JSON for specified type, permissible values are "image" or "container"

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",

 ....
}
]

Getting information on a container

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

Getting the IP address of a container instance

To get the IP address of a container use:

$ docker inspect '{{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 an 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",
