示例1: getTestService

func getTestService(identifier string, requestedPorts ...int32) v1.Service {
	ports := []v1.ServicePort{}
	for _, port := range requestedPorts {
		ports = append(ports, v1.ServicePort{
			Name:     fmt.Sprintf("port-%d", port),
			Protocol: v1.ProtocolTCP,
			Port:     port,
			NodePort: getBackendPort(port),
		})
