# 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>**.
|
|
|
|

|
|
