runc

The runc plan only provides users access to the standalone runc binary. Runc unlike dockerd does not include a running daemon. Instead, it is meant to be executed as a binary or consumed as a library to manage OCI bundle containers.

NAME:
   runc - Open Container Initiative runtime

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.
