K8s-使用nginx入口拒绝连接

我正在学习Kubernetes,我确实在裸机上创建了一个实验室,所以我是Kubernetes的新手!

我确实创造了我的 deployment 它正在运行,可以使用访问 NodePort ,但当我使用 nginx-ingress nginx容器正在运行,它在容器内使用 curl localhost ,但当我从外部世界尝试时,我看到了这条消息: curl: (7) Failed to connect to app.example.com port 80: Connection refused

这些是我的 app-service.yml 和 app-ingress.yml 他们正在运行。

apiVersion: v1
kind: Service
metadata:
  name: my-app-service
spec:
  ports:
  - port: 80
    targetPort: 3010
    protocol: TCP
    name: http
  selector:
    app: my-app

kind: Ingress
metadata:
  name: my-ingress
  labels:
    app: my-app
  annotations:
    # use the shared ingress-nginx
    kubernetes.io/ingress.class: "nginx"
spec:
  rules:
  - host: app.example.com
    http:
      paths:
      - path: /
        backend:
          serviceName: my-app-service
          servicePort: 80

还有我的部署:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: my-app-deployment
  labels:
    app: my-app
spec:
  replicas: 2
  selector:
    matchLabels:
      app: my-app
  template:
    metadata:
      labels:
        app: my-app
    spec:
      containers:
        - name: my-app
          image: my-app:1.0
          ports:
            - containerPort: 3010

命令: kubectl get all --namespace ingress-nginx 显示:
