Install kube-prometheus-stack

Below is the helm command to install kube-prometheus-stack. This installation formally called prometheus-operator also comes with a grafana deployment embedded.

`helm install stable prometheus-community/kube-prometheus-stack -n prometheus`

In order to make prometheus and grafana available outside the cluster, use !NodePort or !LoadBalancer instead of !ClusterIP.

Search `type: ClusterIP` and change it to `type: NodePort` on 

`kubectl edit svc stable-kube-prometheus-sta-prometheus -n prometheus`

and 
 
`kubectl edit svc stable-grafana -n prometheus`




{{{
kubectl get svc -n prometheus


}}}

log into stable-grafana from your PC. Use node port. !Username/Password: `admin` / `prom-operator`
