runc - Open Container Initiative runtime
runc [global options] command [command options] [arguments...]
runc is a command line client for running applications packaged according to the Open Container Format (OCF) 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 ]
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
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
restore restore a container from a previous checkpoint
resume resumes all processes that have been previously paused
spec create a new specification file
start create and run a container
state output the state of a container
help, h Shows a list of commands or help for one command
--debug enable debug output for logging
--log set the log file path where internal debug information is written
--log-format "text" set the format used by logs ('text' (default), or 'json')
--root "/run/opencontainer/containers" root directory for storage of container state (this should be located in tmpfs)
--criu "criu" path to the criu binary used for checkpoint and restore
--systemd-cgroup enable systemd cgroup support, expects cgroupsPath to be of form "slice:prefix:name" for e.g. "system.slice:runc:434234"
--help, -h show help
--version, -v print the version
