kubernetes - Kubernetes Traefik，保持服务不可用

Question

谁知道为什么我的以下YAML代码始终无法获得服务。入口指向服务，该服务指向容器，容器应该可以工作。对于此示例，我仅使用NGINX容器进行测试。

apiVersion: v1
kind: Service
metadata:
  name: frontend
spec:
  selector:
    k8s-app: traefik-ingress-lb
    app: nginx
  ports:
  - name: web
    port: 80
    targetPort: 80

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: frontend
spec:
  rules:
  - host: test.example.services
    http:
      paths:
      - path: /
        backend:
          serviceName: frontend
          servicePort: web

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-deployment
  labels:
    app: nginx
spec:
  replicas: 1
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - name: nginx
        image: nginx:1.15.4
        ports:
        - containerPort: 80

Answer 1

该服务具有应用程序没有的选择器。删除k8s-app: traefik-ingress-lb标签后，一切正常。
