我创建了入口资源，但它不工作。请注意-我没有使用gke默认值部署ingress控制器（在托管gke中部署ingress控制器是强制性的吗）

我分别创建了两个nginx deployment和nodeport服务这里是kubectl get all

=========================

并根据以下yaml部署入口资源

apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: connection
spec:
  rules:
  - http:
      paths:
      - path: /app1
        backend:
          serviceName: app1
          servicePort: 8080
      - path: /app2
        backend:
          serviceName: app2
          servicePort: 80

当我尝试访问http://ingresLBip/app1或http://ingessLBip/app2时，我收到404未找到错误
如果我用单个后端配置ingres资源，那么它将为单个服务工作。
有人在gke上遇到这个问题吗？需要安装nginx控制器吗？
