## Description
|
|
|
|
This command displays system wide information regarding the Docker installation.
|
|
Information displayed includes the kernel version, number of containers and images.
|
|
The number of images shown is the number of unique images. The same image tagged
|
|
under different names is counted only once.
|
|
|
|
If a format is specified, the given template will be executed instead of the
|
|
default format. Go's [text/template](https://pkg.go.dev/text/template) package
|
|
describes all the details of the format.
|
|
|
|
Depending on the storage driver in use, additional information can be shown, such
|
|
as pool name, data file, metadata file, data space used, total data space, metadata
|
|
space used, and total metadata space.
|
|
|
|
The data file is where the images are stored and the metadata file is where the
|
|
meta data regarding those images are stored. When run for the first time Docker
|
|
allocates a certain amount of data space and meta data space from the space
|
|
available on the volume where `/var/lib/docker` is mounted.
|
|
|
|
