当我设置一个入口控制器指向traefik服务时,我希望能够以与LoadBalancer服务相同的方式为GKE上的入口控制器创建负载平衡器。然后我可以指向创建的静态IP。
但是,当我获得我的入口时,没有分配静态IP。
$ kubectl get ingresses -n kube-system

您正在Service为traefik部署创建一个对象,但您已使用该NodePort类型,该类型只能从集群内部访问。如果你想让Kubernetes为a创建一个LoadBalancer Service,你需要LoadBalancer在服务中指定类型,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对话,并为您创建一个带有IP的LoadBalancer。
