    19  ## Description
    20  
    21  This command displays system wide information regarding the Docker installation.
    22  Information displayed includes the kernel version, number of containers and images.
    23  The number of images shown is the number of unique images. The same image tagged
    24  under different names is counted only once.
    25  
    26  If a format is specified, the given template will be executed instead of the
    27  default format. Go's [text/template](https://golang.org/pkg/text/template/) package
    28  describes all the details of the format.
    29  
    30  Depending on the storage driver in use, additional information can be shown, such
    31  as pool name, data file, metadata file, data space used, total data space, metadata
    32  space used, and total metadata space.
    33  
    34  The data file is where the images are stored and the metadata file is where the
    35  meta data regarding those images are stored. When run for the first time Docker
    36  allocates a certain amount of data space and meta data space from the space
    37  available on the volume where `/var/lib/docker` is mounted.
    38  
    39  ## Examples

    41  ### Show output
    42  
    43  The example below shows the output for a daemon running on Ubuntu Linux,
    44  using the `overlay2` storage driver. As can be seen in the output, additional
    45  information about the `overlay2` storage driver is shown:
    46  
    47  ```console
    48  $ docker info
