Answer

  • The low level runtime is called runc
    • It manages every container running on Docker host
    • Its purpose is to interact with the underlying OS to start and stop containers
    • Its reference implementation is of the OCI (Open Containers Initiative) container-runtime-spec
    • It's a small CLI wrapper for libcontainer
