NAME

       docker-system-info - Display system-wide information

SYNOPSIS

       docker system info [OPTIONS]

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 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.

EXAMPLES

Display Docker system information

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