How to access port forward services on gke

votes

I'm new to gke/gcp and this is my first project. I'm setting up istio using https://istio.io/docs/setup/kubernetes/quick-start-gke-dm/ tutorial.

I've exposed grafana as shown in the post using:
kubectl -n istio-system port-forward $(kubectl -n istio-system get pod -l app=grafana -o jsonpath='{.items[0].metadata.name}') 3000:3000 &

curl http://localhost:3000/dashboard/db/istio-dashboard gives me http page on terminal, to access it from the browser I'm using master ip I get after executing kubectl cluster-info.

http://{master-ip}:3000/dashboard/db/istio-dashboard is not accessible.

How do I access services using port-forward on gke?

First grab the name of the Pod

$ kubectl get pod

and then use the port-forward command. 

$ kubectl port-forward <pod-name> 3000:3000

It worked for me, I've found it from this nice website also explained on detail how to do it. Hope it can be useful.

What (exact) http page is returned by the curl command? Both of these docs [1]&[2] suggest using the url (with localhost) in the browser after setting up a tunnel to Grafana: http://localhost:3000/dashboard/db/istio-dashboard

Alternatively, have you tried with istio-ingressgateway IP address?
