I am learning GKE services and have created a GKE cluster with below information

 $ gcloud container clusters list
   NAME       LOCATION    MASTER_VERSION  MASTER_IP       MACHINE_TYPE   NODE_VERSION    NUM_NODES  STATUS
   mycluster  us-east1-b  1.14.10-gke.27  35.X.X.X        n1-standard-1  1.14.10-gke.27  3          RUNNING

I created my own VPC subnet with below range which I assigned to the cluster .

   IP address range : 10.7.0.0/24

The below secondary IP range was assigned by GKE engine

   Secondary IP range

  gke-mycluster-pods-765b8f97       10.44.0.0/14    
  gke-mycluster-services-765b8f97   10.237.0.0/20 

After creating the cluster the node information is as follows:

  $kubectl get nodes          

  NAME                                       STATUS   ROLES    AGE   VERSION
  gke-mycluster-default-pool-c2ddd83e-km5k   Ready    <none>   21m   v1.14.10-gke.27
  gke-mycluster-default-pool-c2ddd83e-trrl   Ready    <none>   21m   v1.14.10-gke.27
  gke-mycluster-default-pool-c2ddd83e-x4w3   Ready    <none>   21m   v1.14.10-gke.27

My deployment YAML is as follows which creates a nginx container:

  apiVersion: apps/v1
  kind: Deployment
  metadata:
     name: mywebapp-replicaset
     labels:
       app: mywebapp
       type: front-end
     spec:
       template:
         metadata:
         name: myngix-pod
           labels:
             app: mywebapp
             type: front-end
  spec:
    containers:
      - name: nginx
        image: nginx
        ports:
          - containerPort: 80
    replicas: 3
    selector:
    matchLabels:
       type: front-end

Below is my service definition

  apiVersion: v1
  kind: Service
  metadata:
     name: mywebapp-services
     labels:
       app: mywebapp
       type: front-end
  spec:
     type: LoadBalancer
     ports:
       - targetPort: 80
         port: 80
     selector:
       app: mywebapp
       type: front-end 

After creating the service using kubectl command , it looks like this

  $ kubectl get services
   NAME                TYPE           CLUSTER-IP      EXTERNAL-IP   PORT(S)        AGE
   kubernetes          ClusterIP      10.237.0.1      <none>        443/TCP        23h
   mywebapp-services   LoadBalancer   10.237.12.141   <pending>     80:31102/TCP   6s

Now if I try to access the LoadBalancer IP from Gcloud shell it is timing out , am I missing something

 $ curl http://10.237.12.141:80
 curl: (7) Failed to connect to 10.237.12.141 port 80: Connection timed out
