in response to a detection from the main process that a plurality of actual resources is present in a node among the plurality of resources, start a subprocess corresponding to each of the plurality of actual resources, and start Remote Procedure Call (RPC) service for each started subprocess; and

register resources, corresponding to a subprocess where the RPC service is successfully started, to a resource manager by means of the main process, enabling the subprocess where the RPC service is successfully started to manage the plurality of actual resources;

wherein the at least one processor further executes the computer program to:

define, by means of the main process, resource names and attributes of preset resource processing interfaces for the plurality of subprocesses respectively.

9. The computer device according to claim 8 , wherein in order to enable the subprocess where the RPC service is successfully started to manage the plurality of actual resources, the at least one processor, upon execution of the computer program, is configured to:

in response to a request, received from the resource manager, to apply for a resource for a container, allocate, by a subprocess corresponding to a resource to be applied for, the resource to be applied for to the container by the RPC service.

10. The computer device according to claim 9 , wherein the at least one processor, upon execution of the computer program, is configured to:

record, by means of the main process, a correspondence between the container and an allocated resource to be applied for; and

generate a persistent file from the correspondence, and store the persistent file to the node.

11. The computer device according to claim 10 , wherein in order to initialize the component to start the main process, the at least one processor, upon execution of the computer program, is configured to:

load the persistent file to acquire a correspondence between a resource and a container of the node.

12. The computer device according to claim 10 , wherein the at least one processor, upon execution of the computer program, is configured to:
