Question

我用印花布和haproxy设置了一个kubernetes单节点主平面。现在，每当我要创建一个Ingress时，该地址将保持为空，服务器将返回503错误。

以下显示了我的kubernetes部署。

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-deployment
spec:
  selector:
    matchLabels:
      app: nginx
  replicas: 1
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
        - name: nginx
          image: wordpress
          ports:
            - containerPort: 8080
---
apiVersion: v1
kind: Service
metadata:
  name: nginx-service
spec:
  ports:
    - port: 8080
      targetPort: 8080
      protocol: TCP
  selector:
    app: nginx
---
apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: web-ingress
spec:
  rules:
    - host: wordpress.example.org
      http:
        paths:
          - path: /
            backend:
              serviceName: nginx-service
              servicePort: 8080

这是我从kubernetes cl中获得的输出。

我希望入口将接收服务的群集ip，并且正在侦听给定的主机uri，并提供除给定的503错误之外的其他信息。

Answer 1

服务的默认类型是ClusterIP，但仅用于群集内部通信。对于外部流量，应切换到NodePort类型。例如：

apiVersion: v1
kind: Service
metadata:
  name: nginx-service
spec:
  type: NodePort
  ports:
    - port: 80
      targetPort: 8080
      protocol: TCP
      name: http
  selector:
    run: nginx

如果我没记错的话，nginx alb控制器允许使用ClusterIP（或LoadBalancer）。

此图像的容器端口是80，而我暴露了8080。

Kubernetes Ingress无法获取服务的集群IP
