Cause analysis

Finalizers is an asynchronous pre delete hook commonly used by operators of kubernetes. When this resource is deleted, it needs to be cleaned up by the program that created the resource before deletion. After cleaning up, it needs to remove the identifier from the finalizers of the resource, and then the resource will be completely deleted
