    19## Description
    20
    21This command displays system wide information regarding the Docker installation.
    22Information displayed includes the kernel version, number of containers and images.
    23The number of images shown is the number of unique images. The same image tagged
    24under different names is counted only once.
    25
    26If a format is specified, the given template will be executed instead of the
    27default format. Go's [text/template](https://pkg.go.dev/text/template) package
    28describes all the details of the format.
    29
    30Depending on the storage driver in use, additional information can be shown, such
    31as pool name, data file, metadata file, data space used, total data space, metadata
    32space used, and total metadata space.
    33
    34The data file is where the images are stored and the metadata file is where the
    35meta data regarding those images are stored. When run for the first time Docker
    36allocates a certain amount of data space and meta data space from the space
    37available on the volume where `/var/lib/docker` is mounted.

    43The example below shows the output for a daemon running on Ubuntu Linux,
    44using the `overlay2` storage driver. As can be seen in the output, additional
    45information about the `overlay2` storage driver is shown:
