IP address and port, but access s Ervice this virtual IP and port, the service forwards the request to the pod behind it.Kubernetes, when creating a service, finds the pod based on the service's label selector (label Selector), creating a endpoints object with the same name as the service. When the address of the pod changes, the endpoints changes as well. When the service accepts the request, it can find the destination address of the request forwarding through endpoints.For example, the autho
