Core/Base package repository performs the mounting operation in a specific directory on the host, which can adapt to the container image overlay scenario. The offloaded management-plane process can construct a working directory for the output streams of the remotely started processes and monitor the status to ensure the lifecycle consistency of the processes at both ends. By combining these mechanisms, policies can be tailored for different
