NAME

runc - Open Container Initiative runtime

SYNOPSIS

runc [global options] command [command options] [arguments...]

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 start a new instance of a container:

    # runc start [ -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
   delete delete any resources held by the container often used with detached containers
   events display container events such as OOM notifications, cpu, memory, IO and network stats
   exec execute new process inside the container
   init initialize the namespaces and launch the process (do not call it outside of runc)
   kill kill sends the specified signal (default: SIGTERM) to the container's init process
   list lists containers started by runc with the given root
   pause pause suspends all processes inside the container
   ps displays the processes running inside a container
   restore restore a container from a previous checkpoint
   resume resumes all processes that have been previously paused
   run create and run a container
   spec create a new specification file
   start executes the user defined process in a created container
   state output the state of a container
   update update container resource constraints
   help, h Shows a list of commands or help for one command

GLOBAL OPTIONS

--debug enable debug output for logging
   --log value set the log file path where internal debug information is written (default: "/dev/null")
   --log-format value set the format used by logs ('text' (default), or 'json') (default: "text")
   --root value root directory for storage of container state (this should be located in tmpfs) (default: "/run/runc")
   --criu value path to the criu binary used for checkpoint and restore (default: "criu")
