 # NAME
 docker \- Docker image and container command line interface
 
 # SYNOPSIS
 **docker** [OPTIONS] COMMAND [arg...]
 

 **docker** daemon [ --help | ... ]
 
 **docker** [ --help | -v | --version ]
 

 # 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 daemon, and a client

 to the daemon, through the CLI.
 

 To run the Docker daemon you can specify **docker daemon**.
 You can view the daemon options using **docker daemon --help**.
 To see the man page for the daemon, run **man docker daemon**.

 
 The Docker CLI has over 30 commands. The commands are listed below and each has

 its own man page which explain usage and arguments.

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

 **--help**

   Print usage statement
 

 **--config**=""
   Specifies the location of the Docker client configuration files. The default is '~/.docker'.
 

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

 **-H**, **--host**=[unix:///var/run/docker.sock]: tcp://[host]:[port][path] to bind or

 unix://[/path/to/socket] to use.
   The socket(s) to bind to in daemon mode specified using one or more

   tcp://host:port/path, unix:///path/to/socket, fd://* or fd://socketfd.
   If the tcp port is not specified, then it will default to either `2375` when
   `--tls` is off, or `2376` when `--tls` is on, or `--tlsverify` is specified.

 **-l**, **--log-level**="*debug*|*info*|*warn*|*error*|*fatal*""

   Set the logging level. Default is `info`.
 

 **--tls**=*true*|*false*

 **--tlscert**=~/.docker/cert.pem
   Path to TLS certificate file.
 
 **--tlskey**=~/.docker/key.pem
   Path to TLS key file.
 
 **--tlsverify**=*true*|*false*

   Use TLS and verify the remote (daemon: verify client, client: verify daemon).
   Default is false.
 
 **-v**, **--version**=*true*|*false*

   Print version information and quit. Default is false.

 # EXEC DRIVER OPTIONS
 

 Use the **--exec-opt** flags to specify options to the exec-driver. The only
 driver that accepts this flag is the *native* (libcontainer) driver. As a
 result, you must also specify **-s=**native for this option to have effect. The 
 following is the only *native* option:

 
 #### native.cgroupdriver

 Specifies the management of the container's `cgroups`. You can specify 
 `cgroupfs` or `systemd`. If you specify `systemd` and it is not available, the 
 system uses `cgroupfs`.

 #### Client

 For specific client examples please see the man page for the specific Docker
 command. For example:

     man docker-run
