DOCKER(1)

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 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

    =[/var/run/docker.sock] is omitted, default values are used.

--api-enable-cors=false
    Enable CORS headers in the remote API

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