nginx - 在 GKE 专用集群上创建入口资源时超时

Question

创建了一个 GKE 集群，设置 cloud-nat 以实现互联网连接。然后我部署了 kubernetes ingress-nginx kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/static/provider/cloud/deploy.yaml。

到这里为止一切都很好，但是当我尝试部署 ingress 资源 时，我从服务器收到此 错误(超时):创建“manifests/backend/service/be-nginx”时出错-ingress-service.yaml": 超时:请求未在请求的超时 30 秒内完成。

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: ingress-resource
  namespace: sap
  annotations:
    kubernetes.io/ingress.class: nginx
spec:
  tls:
    - hosts:
      - mywebname.com
      secretName: ingress-tls
  rules:
    - host: mywebname.com
      http:
        paths:
        - path: /
          backend:
            serviceName: app
            servicePort: 5000
        - path: /v1
          backend:
            serviceName: web
            servicePort: 8081

我的 list 在公共(public) GKE 上运行良好，但今天我将其切换为私有(private)，我遇到了这个问题，这是我第一次使用 VPC，任何帮助或指导将不胜感激，谢谢

我很确定这是防火墙的问题。你遵守文件了吗？

https://kubernetes.github.io/ingress-nginx/deploy/#gce-gke

For private clusters, you will need to either add an additional firewall rule that allows master nodes access port 8443/tcp on worker nodes, or change the existing rule that allows access to ports 80/tcp, 443/tcp and 10254/tcp to also allow access to port 8443/tcp.

https://cloud.google.com/kubernetes-engine/docs/how-to/private-clusters#add_firewall_rules

gcloud compute firewall-rules create firewall-rule-name \
    --action ALLOW \
    --direction INGRESS \
    --source-ranges master-CIDR-block \
    --rules protocol:port \
    --target-tags target
