Kubernetes Setup for Prometheus and Grafana

Quick start

To quickly start all the things just do this:

kubectl apply \
  --filename https://raw.githubusercontent.com/artempronevskiy/kubernetes-prometheus/master/manifests-all.yaml

This will create the namespace monitoring and bring up all components in there.

To shut down all components again you can just delete that namespace:

kubectl delete namespace monitoring

Default Dashboards

If you want to re-import the default dashboards from this setup run this job:

kubectl apply --filename ./manifests/grafana/import-dashboards/job.yaml

In case the job already exists from an earlier run, delete it before:

kubectl --namespace monitoring delete job grafana-import-dashboards

To access grafana you can use port forward functionality

export POD_NAME=$(kubectl get pods --namespace monitoring -l "app=grafana,component=core" -o jsonpath="{.items[0].metadata.name}")

kubectl port-forward --namespace monitoring $POD_NAME 3000:3000

And you should be able to access grafana on http://localhost:3000/login
