Cant configure ingress on gcloud properly - kubernetes

Question

I am trying to deploy a simple app on google cloud. I am testing the gitlab kluster integration.
Here is my yaml k8:
---
apiVersion: v1
kind: Service
metadata:
name: service
namespace: "my-service"
labels:
run: service
spec:
type: NodePort
selector:
run: "service"
ports:
- port: 9000
targetPort: 9000
protocol: TCP
name: http
---
apiVersion: v1
kind: ServiceAccount
metadata:
name: service-api
namespace: "my-service"
labels:
run: service
---
apiVersion: apps/v1
kind: Deployment
metadata:
name: service-v1
namespace: "my-service"
labels:
run: service
spec:
replicas: 1
selector:
matchLabels:
run: service
template:
metadata:
labels:
run: service
spec:
serviceAccountName: service-api
containers:
- name: service
image: "gcr.io/test/service:latest"
imagePullPolicy: IfNotPresent
ports:
- containerPort: 9000
protocol: TCP
volumeMounts:
- name: test
mountPath: /usr/test
volumes:
- name: test
emptyDir: {}
---
apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
name: "service-ingress"
namespace: "my-service"
labels:
run: service
spec:
rules:
- http:
paths:
- path: /*
backend:
serviceName: service
servicePort: 9000
If I log into the pod I can curl the service on the nodePort designed IP, but if I try to hit the ingress address I just get a error:
I am not sure why there are 2 backend services on the loadbalancer that is created automatically, the one that points to my app shows as unhealthy

You need to define readiness probe in your pod spec because GKE ingress controller picks up health check from the readiness probe.
apiVersion: apps/v1
kind: Deployment
metadata:
name: service-v1
namespace: "my-service"
labels:
run: service
spec:
replicas: 1
selector:
matchLabels:
run: service
template:
metadata:
labels:
run: service
spec:
serviceAccountName: service-api
containers:
- name: service
image: "gcr.io/test/service:latest"
imagePullPolicy: IfNotPresent
readinessProbe:
httpGet:
path: /healthz
port: 8080
initialDelaySeconds: 3
periodSeconds: 3
ports:
- containerPort: 9000
protocol: TCP
volumeMounts:
- name: test
mountPath: /usr/test
volumes:
- name: test
emptyDir: {}
