# NAME
docker \- Docker image and container command line interface

# SYNOPSIS
**docker** [OPTIONS] COMMAND [arg...]

# DESCRIPTION
**docker** has two distinct functions. It is used for starting the Docker
daemon and to run the CLI (i.e., to command the daemon to manage images,
containers etc.) So **docker** is both a server, as a deamon, and a client
to the daemon, through the CLI.

To run the Docker deamon you do not specify any of the commands listed below but
must specify the **-d** option.  The other options listed below are for the
daemon only.

The Docker CLI has over 30 commands. The commands are listed below and each has
its own man page which explain usage and arguements.

To see the man page for a command run **man docker <command>**.

# OPTIONS
**-D**=*true*|*false*
   Enable debug mode. Default is false.

**-H**, **--host**=[unix:///var/run/docker.sock]: tcp://[host[:port]] to bind or
unix://[/path/to/socket] to use.
   Enable both the socket support and TCP on localhost. When host=[0.0.0.0],
port=[4243] or path =[/var/run/docker.sock] is omitted, default values are used.

**--api-enable-cors**=*true*|*false*
  Enable CORS headers in the remote API. Default is false.

**-b**=""
  Attach containers to a pre\-existing network bridge; use 'none' to disable container networking

  Use the provided CIDR notation address for the dynamically created bridge (docker0); Mutually exclusive of \-b

**-d**=*true*|*false*
  Enable daemon mode. Default is false.

**--dns**=""
  Force Docker to use specific DNS servers

**-g**=""
  Path to use as the root of the Docker runtime. Default is `/var/lib/docker`.

**--icc**=*true*|*false*
  Enable inter\-container communication. Default is true.

**--ip**=""
  Default IP address to use when binding container ports. Default is `0.0.0.0`.

**--iptables**=*true*|*false*
  Disable Docker's addition of iptables rules. Default is true.

**--mtu**=VALUE
  Set the containers network mtu. Default is `1500`.

**-p**=""

**-r**=*true*|*false*
  Restart previously running containers. Default is true.

**-s**=""
  Force the Docker runtime to use a specific storage driver.

**-v**=*true*|*false*
