如何在GKE中使用臨時IP創建Kubernetes負載均衡器？

Question

如何配置LoadBalancer來檢索臨時IP而不是靜態IP？

我需要這個，所以我不必等待GOOGLE從1個IP地址增加配額...（這已經是漫長的一天了……）

  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

刪除loadBalancerIp字段並重新創建服務后，它仍保持待處理狀態。

這是kubectl get service ****** -o yaml的輸出：

kubectl get service **** -o yaml
apiVersion: v1
kind: Service
metadata:
  annotations:
    kubectl.kubernetes.io/last-applied-configuration: |
      {"apiVersion":"v1","kind":"Service","metadata":{"annotations":{},"labels":{"app":"api"},"name":"subzero-react","namespace":"default"},"spec":{"ports":[{"name":"http","port":80}],"selector":{"app":"initial-pp3subzero"},"type":"LoadBalancer"}}

為了不分配與Kubernetes（默認行為）一個GCP負載平衡器的靜態IP，你一般不需要在指定任何loadBalancerIP服務規范描述在這里和這里 。

您可以刪除服務並在沒有loadBalancerIP情況下重新創建它，也可以對其進行修補：

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