Multi-Kubernetes cluster management method and system based on OCM

The invention relates to the technical field of cloud platforms, and particularly discloses a multi-Kubernetes cluster nano-management method and system based on an OCM, and the method comprises the steps: building a plurality of user-defined resource clusters through a crd mode, and the plurality of user-defined resource clusters comprise a hub cluster and a managed cluster; component deployment is carried out on the hub cluster and the managed cluster; the component changes a cluster crd state according to the hub cluster and the managed cluster, and performs nano-management task circulation according to a change result; wherein the component is a controller or an OCM (optical control module) component. According to the method disclosed by the invention, centralized management of the multiple Kubernetes clusters is realized, meanwhile, the management efficiency and the operation security are improved in an automatic and security authorization mode, and the method is suitable for a scene in which efficient m
