Setting up promeheuts in 3 steps

Install it locally

brew install helm

helm install stable/prometheus

kubectl expose deployment callous-chipmunk-prometheus-server --name=prometheus-endpoint --type=LoadBalancer

helm install stable/grafana

kubectl expose deployment wiggly-zebra-grafana --name=grafana-endpoint --type=LoadBalancer

And expose the service again, as you did with prometheus.

   kubectl get secret --namespace default wiggly-zebra-grafana -o jsonpath="{.data.grafana-admin-password}" | base64 --decode ; echo

Will give you the 'admin' password, to login, and build a dashboard against your promteheus instance.
