Prometheus and external Grafana setup

Cluster information:

Kubernetes version: v1.17.3
Installation method: kubeadm, 1 master, 4 nodes.
Host OS: Linux Debian

Hello! I want to use this dashboard in my grafana: Kubernetes cluster monitoring (via Prometheus) dashboard for Grafana | Grafana Labs. To do this, I’ve installed prometheus operator using this article: Installing Prometheus Operator with Grafana Cloud for Kubernetes | Grafana Labs. It works, but scrapes only prometheus internal metrics and is not useful.

I tried to change config using kubectl edit secrets prometheus-prometheus and replacing config (to add recommended part from dashboard docs), but it doesn’t work - config just returns in the old state.

Please, help me to change the config or reinstall prometheus to monitor the whole my cluster :slight_smile:
