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 Project 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.
After creating a spec for your root filesystem with runc, you can execute a simple container in your shell by running:
cd /mycontainer
runc
