How can I create Kubernetes load balancer with an ephemeral IP in GKE?

Question

How can I configure a LoadBalancer to retrieve a ephemeral rather than static IP?

I need this so I don't have to WAIT FOR GOOGLE TO INCREASE THE QUOTA FROM 1 IP ADDRRESS... (It's been a long day...)

  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

Upon removing the loadBalancerIp field and recreating the service, it still remains in pending.

This is the output of kubectl get service ****** -o yaml :

To not assign a static IP on a GCP load balancer with Kubernetes (default behavior) you generally don't need to specify anything in the loadBalancerIP service spec as described here and here .

You can delete your service and re-create it without the loadBalancerIP or you can patch it:

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