# 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
|
