没有创建负载均衡器并将静态 ip 分配给 GKE 上的 traefik ingress

Question

当我设置入口控制器以指向 traefik 服务时，我希望在 GKE 上为该入口控制器创建负载均衡器，方式与 LoadBalancer 服务相同。然后我可以指向创建的静态 ip。

但是，当我进入入口时，没有分配静态 IP。

$ kubectl get ingresses -n kube-system
NAME              HOSTS                 ADDRESS   PORTS     AGE
traefik-ingress   traefik-ui.minikube             80        4m

traefik-ingress.yml

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: traefik-ingress
  namespace: kube-system
  annotations:
    kubernetes.io/ingress.class: traefik
spec:
  rules:
    - host: traefik-ui.minikube
      http:
        paths:
          - path: "/"
            backend:
              serviceName: traefik-ingress-service
              servicePort: 80

您正在为 traefik 部署创建一个 Service 对象，但您使用了 NodePort 类型，该类型只能从集群内部访问。如果你想让 Kubernetes 为 Service 创建一个 LoadBalancer，你需要在你的服务中指定类型 LoadBalancer，所以你的 traefik Service 看起来像

kind: Service
apiVersion: v1
metadata:
  name: traefik-ingress-service
  namespace: kube-system
spec:
  selector:
    k8s-app: traefik-ingress-lb
  ports:
    - protocol: TCP
      port: 80
      name: web
    - protocol: TCP
      port: 8080
      name: admin
  type: LoadBalancer

这将与 GKE API 通信并为您创建一个带有 IP 的 LoadBalancer。
