kubernetes - 如何在GKE中使用临时IP创建Kubernetes负载均衡器？

Question

如何配置LoadBalancer来检索临时IP而不是静态IP？

我需要这个，所以我不必等待GOOGLE从1个IP地址增加配额...(这已经是漫长的一天了...)

  Normal   EnsuringLoadBalancer        3m (x7 over 8m)  service-controller  Ensuring load balancer
  Warning  CreatingLoadBalancerFailed  3m (x7 over 8m)  service-controller  Error creating load balancer (will retry): failed to ensure load balancer for service default/subzero-react: failed to ensure a static IP for load balancer (*****************(default/subzero-react)): error creating gce static IP address: googleapi: Error 403: Quota 'STATIC_ADDRESSES' exceeded. Limit: 1.0 in region us-central1., quotaExceeded

删除 loadBalancerIp字段并重新创建服务后，它仍处于待处理状态。

这是 kubectl get service ****** -o yaml的输出:

kubectl get service **** -o yaml
apiVersion: v1

要在不使用Kubernetes的GCP负载均衡器上分配静态IP(默认行为)，通常不需要在loadBalancerIP服务规范中指定任何内容，如here和here所述。

您可以删除服务并重新创建它，而无需使用loadBalancerIP，也可以对其进行修补:

$ kubectl patch service <service-name> -p '{"spec": { "loadBalancerIP": null }}'
