| 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 |
