DOCKER(1)

NAME

docker - Docker image and container command line interface

SYNOPSIS

docker OPTIONS (#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 daemon, and a client to the daemon, through the CLI.

To run the Docker daemon 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 arguments.

To see the man page for a command run man docker .

OPTIONS

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

--help Print usage statement

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

--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

--bip="" 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="" Path to use for daemon PID file. Default is /var/run/docker.pid

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

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

-v=true|false Print version information and quit. Default is false.

--selinux-enabled=true|false Enable selinux support. Default is false. SELinux does not presently support the BTRFS storage driver.
