CRIU-based Pod thermal migration method

The invention provides a Pod thermal migration method based on CRIU, and belongs to the technical field of cloud environment container arrangement. According to the method, the CRIU is used, and the smooth migration of the Pod is realized under the condition that the service is not interrupted by changing a Kubernetes sub-component; an identifier is added in a Pod definition, a CRIU is called in preparation before migration to store a container process state, and data synchronization is ensured; on the target node, the process state is recovered through the CRIU, so that the original state is recovered; then, the Pod runs again, and finally migration is completed. According to the method, the problem that the Pod cannot be migrated from one node to another node under the conditions of node fault maintenance and service continuous operation maintenance is solved, the continuous operation of the application is ensured, and the downtime of the system is reduced. 本发明提供了一种基于CRIU的Pod热迁移方法，属于云环境容器编排技术领域。本发明使用CRIU，通过
