I had deployed ravendb on a 3 node cluster on google cloud. However it's not accessible from the browser. Here is the procedure and the configuration I had followed. Could you please help me troubleshoot the service and deployment. When I run the get pods and get svc commands the pods and services are running but the db isn't accessible from the browser.

Procedure followed:

I suggest you first run the setup wizard on your local dev machine and get the Let's Encrypt certificate. Just use 127.0.0.1:8080 as the IP, it's not important at the moment.
(Even better will be to get your own domain + certificate for production use)

You need to convert both the pfx file and the license.json file to base64, In c# for example:
Convert.ToBase64String(File.ReadAllBytes(@"C:\work\certs\cluster.server.certificate.iftah.pfx"))

Convert.ToBase64String(File.ReadAllBytes(@"C:\work\license.json"))

1. Create a GKE standard cluster with 3 nodes, no special settings. Let's call it raven-cluster
2. Install gcloud and kubectl (follow the getting started guide: https://cloud.google.com/kubernetes-engine/docs/quickstart)
run:
3. > gcloud container clusters get-credentials raven-cluster
4. > kubectl create clusterrolebinding my-cluster-admin-binding --clusterrole cluster-admin --user $(gcloud config get-value account)

Now you're ready to deploy. 
Edit the cluster.yaml file to include the base64 certificate (name: raven-ssl)
Edit the license.secret.yaml file to include the base64 license (name: ravendb-license)

4a) kubectl label node role=ingress-controller --all
5. kubectl create -f license.secret.yaml
6. kubectl create -f haproxy.yaml
7. kubectl create -f cluster.yaml
9. kubectl get pod
8. kubectl get svc
