version

Usage: docker version [OPTIONS]

Show the Docker version information.

  -f, --format=""    Format the output using the given go template
  --help=false       Print usage

By default, this will render all version information in an easy to read layout. If a format is specified, the given template will be executed instead.

Go's text/template package describes all the details of the format.
