GKE - how to attach static ip to internal load balancer - google-cloud-platform

Question

I want to connect service from one GKE cluster to another one. I created service as a internal load balancer and I would like to attach a static ip to it. I created my service.yml
apiVersion: v1
kind: Service
metadata:
name: ilb-service
annotations:
cloud.google.com/load-balancer-type: "Internal"
kubernetes.io/ingress.global-static-ip-name: es-test
labels:
app: hello
spec:
type: LoadBalancer
selector:
app: hello
ports:
- port: 80
targetPort: 8080
protocol: TCP
However after apply -f when I check the service the load balancer ingress looks like this:
status:
loadBalancer:
ingress:
- ip: 10.156.0.60
And I cannot connect using the static ip. How to solve it ?
EDIT:
After suggestion I changed the yml file to:
apiVersion: v1
kind: Service
metadata:
name: ilb-service
annotations:
cloud.google.com/load-balancer-type: "Internal"
labels:
app: hello
spec:
type: LoadBalancer
selector:
app: hello
ports:
- port: 80
targetPort: 8080
protocol: TCP
loadBalancerIP: "xx.xxx.xxx.xxx" -- here my static ip
Service now looks like it:
spec:
clusterIP: 11.11.1.111
externalTrafficPolicy: Cluster
loadBalancerIP: xx.xxx.xxx.xxx
ports:
- nodePort: 31894
port: 80
protocol: TCP
targetPort: 8080
selector:
app: hello
sessionAffinity: None
type: LoadBalancer
status:
loadBalancer: {}
And I still cannot connect

It is possible to create a static internal IP and assign it to a LoadBalancer k8s service type.
Go to the VPC networks -> Select your VPC -> Static Internal IP Addresses
Click Reserve Static Address, then select a name for your IP and click Reserve. You can choose IP address manually here as well.
In your Service YAML add the following annotation. Also make sure type is LoadBalancer and then assign the IP address.
...
annotations:
networking.gke.io/load-balancer-type: "Internal"
...
type: LoadBalancer
loadBalancerIP: <your_static_internal_IP>
This will spin up an internal LB and assign your static IP to it. You can also check in Static Internal IP Addresses screen that new IP is now in use by freshly created load balancer. You can assign a Cloud DNS record to it, if needed.
Also, you can choose IP address "shared" during the reservation process so it can be used by up to 50 internal load balancers.
