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:
