With the surge of demand for edge computing, cloud edge collaboration has become an important evolution direction. One of the difficulties of cloud edge collaboration development lies in the deployment, management, update and upgrade of edge end and applications running on it. Container technology provides ideas for solving the above problem. Based on the lightweight, fast deployment, and easy portability characteristics of container technology, an efficient cloud edge application control method based on containerization was studied, including adding container design to the overall architecture of cloud edge collaboration and using container based application collaboration design; studying the cloud deployment update management mechanism; conducting research and implementation on the design content of container application deployment and updates, as well as container and application distribution. Experimental verification showed that this method could significantly improve system energy consumption, efficiency, computational latency, and cloud CPU utilization efficiency, thereby improving system update rate and increasing the number of available edge nodes on the server and data processing capacity. It could greatly optimize the cloud edge collaborative system and also greatly improve the overall system's computing power. The application of this technology can improve the problems of tight computing resources, heterogeneous edge devices, and complex and diverse service management requirements on the edge of the Power Grid smart electricity platform, achieving efficient application control of the Power Grid smart electricity cloud edge collaborative platform.
