kubernetes on google failed to create load balancer ip static

Question

Although I reserved a static IP I got the following warning, while not having load balancer created :

> kubectl describe svc --namespace=api-1dt-dc

Answer 1

OK, it seems to work only with regional IPs...

Answer 2

As Thomas Parquier said higher, it can be related to the fact that is not a regional ip.

Taking this service as an example:

apiVersion: v1
kind: Service
metadata:
  name: my-service-name
  annotations:
spec:
  selector:
    app: deployment-name
  clusterIP: 10.0.5.890
  externalTrafficPolicy: Cluster
  ports:
    - name: https
      port: 443
      protocol: TCP
      targetPort: 443
  sessionAffinity: None
  type: LoadBalancer
  loadBalancerIP: "72.229.?.?"

First delete your service

kubectl delete svc my-service-name;

Remove loadBalancerIP line (last one) from your Service and apply fixes:

kubectl apply -f my-service-name.yaml

Then, wait that an EXTERNAL_IP ip address has been assigned to your service

kubectl get svc;

Mark this address as static in google console https://console.cloud.google.com/networking/addresses/list

And finally, assign newly ip address to loadBalancerIP line in your Service

Answer 3

Hitting same issue while trying to expose with LoadBalancer.

  Normal   EnsuredLoadBalancer         2m (x2 over 1h)  service-controller  Ensured load balancer
  Warning  CreatingLoadBalancerFailed  2m (x2 over 1h)  service-controller  Error creating load balancer (will retry): not persisting update to service 'default/cb-gke-demo-ui' that has been changed since we received it: Operation cannot be fulfilled on services "cb-gke-demo-ui": the object has been modified; please apply your changes to the latest version and try again

Not sure how to fix it? GKE k8s cluster is deployed across AZz.
