The central cloud cluster service receives a workload creation request initiated by a client and forwards the workload creation request to a central control node for analysis to obtain a container group description file; generating a container group creation request based on the container group description file and distributing the container group creation request to a target virtual workload node;
wherein the central cloud cluster service comprises: the method for realizing the edge cloud cluster service system comprises the steps of accessing the sub-service, distributing the sub-service and calling the sub-service, and further comprises the following steps:
the access sub-service receives a workload creation request initiated by a client, and analyzes the workload creation request based on a preset workload template to obtain a container group description file, wherein the workload template is used for standardizing a part of target states of specified load resources when a workload is operated; the allocation sub-service generates a container group creation request based on the container group description file and allocates the container group creation request to a target virtual workload node; the calling sub-service calls the central cloud scheduling service and forwards the container group description file to the central cloud scheduling service through the target virtual workload node;
The central cloud scheduling service receives and analyzes a container group creation request initiated by the target virtual workload node to obtain a container group instance description file; generating a container group instance creation request based on the container group instance description file;
The edge container service receives a container group instance creation request initiated by a central cloud scheduling service, creates a new container group instance in a host machine of an edge machine room associated with the target virtual workload node according to the container group instance creation request and operates, wherein the edge container service comprises an edge container service control end and edge container service clients, the edge container service clients are deployed on each host machine of the edge machine room, and the edge container service control end is used for managing the edge container service clients and providing resource caching, request distribution, monitoring and scheduling functions of the container group instance based on the edge container service clients; the edge container service is further to: and reporting the container group state in the host machine of each edge machine room to the central dispatching service at fixed time so that the central dispatching service can be synchronized to the central cloud through the virtual workload node.
