Grafana on the EKS cluster

[ackintosh]

Added a script to make it easy to create a Grafana instance in which our dashboards are preset, on the EKS cluster.

$ ./monitoring.sh

$ export POD_NAME=$(kubectl get pods --namespace default -l "app.kubernetes.io/name=grafana,app.kubernetes.io/instance=gossipsub-grafana" -o jsonpath="{.items[0].metadata.name}")

$ kubectl --namespace default port-forward $POD_NAME 3000
