runc(8)

NAME

runc - Open Container Initiative runtime

SYNOPSIS

runc [global-option ...] command [command-option ...] [argument ...]

DESCRIPTION

runc is a command line client for running applications packaged according to the Open Container Initiative (OCI) format and is a compliant implementation of the Open Container Initiative specification.

runc integrates well with existing process supervisors to provide a production container runtime environment for applications. It can be used with your existing process monitoring tools and the container will be spawned as a direct child of the process supervisor.

Containers are configured using bundles. A bundle for a container is a directory that includes a specification file named config.json and a root filesystem. The root filesystem contains the contents of the container.

To run a new instance of a container:

    # runc run [ -b bundle ] container-id

Where container-id is your name for the instance of the container that you are starting. The name you provide for the container instance must be unique on your host.

Providing the bundle directory using -b is optional. The default value for bundle is the current directory.

COMMANDS

checkpoint
    Checkpoint a running container. See runc-checkpoint(8).

create
    Create a container. See runc-create(8).

delete
    Delete any resources held by the container; often used with detached containers. See runc-delete(8).

events
    Display container events, such as OOM notifications, CPU, memory, I/O and network statistics. See runc-events(8).

exec
    Execute a new process inside the container. See runc-exec(8).

kill
    Send a specified signal to the container's init process. See runc-kill(8).

list
    List containers started by runc with the given --root. See runc-list(8).

pause
    Suspend all processes inside the container. See runc-pause(8).

ps  Show processes running inside the container. See runc-ps(8).

restore
    Restore a container from a previous checkpoint. See runc-restore(8).

resume
    Resume all processes that have been previously paused. See runc-resume(8).

run Create and start a container. See runc-run(8).

spec
    Create a new specification file (config.json). See runc-spec(8).

start
    Start a container previously created by runc create. See runc-start(8).

state
    Show the container state. See runc-state(8).

update
    Update container resource constraints. See runc-update(8).

help, h
    Show a list of commands or help for a particular command.

GLOBAL OPTIONS

These options can be used with any command, and must precede the command.

--debug
    Enable debug logging.

--log path
    Set the log destination to path. The default is to log to stderr.

--log-format text|json
    Set the log format (default is text).

--root path
    Set the root directory to store containers' state. The path should be located on tmpfs. Default is /run/runc, or $XDG_RUNTIME_DIR/runc for rootless containers.

--criu path
    Set the path to the criu(8) binary used for checkpoint and restore. Default is criu.

--systemd-cgroup
    Enable systemd cgroup support. If this is set, the container spec (config.json) is expected to have cgroupsPath value in the slice:prefix:name form (e.g. system.slice:runc:434234).

--rootless true|false|auto
    Enable or disable rootless mode. Default is auto, meaning to auto-detect whether rootless should be enabled.

--help|-h
    Show help.

--version|-v
    Show version.
