Passwords here are placeholders (change-me). The generator creates random ones for you.

How to use it

kubectl create namespace monitoring --dry-run=client -o yaml | kubectl apply -f -
kubectl apply -f grafana.yaml
kubectl -n monitoring get pods -w

• Log in as admin with the password from the Secret. Open it with kubectl -n monitoring port-forward svc/grafana 3000:3000.
