Question

我正在尝试在Google云引擎中设置traefik负载均衡器。我的配置：

kind: Deployment
apiVersion: extensions/v1beta1
metadata:
  name: traefik-ingress-controller
  namespace: default
  labels:
    k8s-app: traefik-ingress-lb
spec:
  replicas: 2
  template:
    metadata:
      labels:
        app: traefik-ingress-lb
        name: traefik-ingress-lb
      annotations:
         traefik.ingress.kubernetes.io/frontend-entry-points: http,https
    spec:
      terminationGracePeriodSeconds: 60
      serviceAccountName: traefik-ingress-controller
      volumes:
        - name: config
          configMap:
            name: traefik-config
      containers:
      - image: traefik
        name: traefik-ingress-lb
        imagePullPolicy: Always
        volumeMounts:
          - mountPath: "/config"
            name: "config"
        ports:
        - name: admin
          containerPort: 8080
        - name: http
          containerPort: 80
          #hostPort: 80
        - name: https
          containerPort: 443
        args:
        - --api
        - --kubernetes
        - --logLevel=DEBUG
---
kind: Service
apiVersion: v1
metadata:
  name: traefik-ingress-service
  namespace: default
spec:
  type: LoadBalancer
  selector:
    k8s-app: traefik-ingress-lb
  ports:
    - name: http
      protocol: TCP
      port: 80
      targetPort: 80
    - name: https
      protocol: TCP
      port: 443
      targetPort: 443
    - name: admin
      protocol: TCP
      port: 8080

Traefik ui：

apiVersion: v1
kind: Service
metadata:
  name: traefik-web-ui
  namespace: default
spec:
  selector:
    k8s-app: traefik-ingress-lb
  ports:
    - protocol: TCP
      port: 8080
---
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: traefik-web-ui
  namespace: default
  annotations:
    kubernetes.io/ingress.class: traefik
spec:
  rules:
  - http:
      paths:
      - path: /
        backend:
          serviceName: traefik-web-ui
          servicePort: 8080

不幸的是，这不起作用。服务和Pod正在运行，没有错误。但是，当我尝试连接时，它正在无限加载（有趣的是ping有效）。如果我将配置调整为使用hostPort，则它适用于一个Pod。永远不会创建另一个Pod，因为第一个Pod已使用hostPort（错误：pod无法容纳主机端口）。

那么如何解决此问题以在不使用妖怪的情况下使用多个Pod？

如果需要将其连接到Google Cloud Load Balancer，则需要VM中的主机端口。发生的情况是Kubernetes可能在主机上为其提供了一个随机端口，但您的Google Cloud Load Balancer指向80。您可能想尝试在服务上为服务中的后端端口名称分配targetPort。我认为您的情况就是http或https或admin。

kind: Service
apiVersion: v1
metadata:
  name: traefik-ingress-service
  namespace: default
spec:
  type: LoadBalancer
  selector:
    k8s-app: traefik-ingress-lb
  ports:
    - name: http
      protocol: TCP
      port: 80
      targetPort: http
    - name: https
      protocol: TCP
      port: 443
      targetPort: https
    - name: admin
      protocol: TCP
      port: 8080
      targetPort: admin

希望有帮助！

没有hostPort不能运行Traefik负载均衡器
