This tutorial uses Helm to install Scaphandre, Prometheus and Grafana.

Install Scaphandre

First we install Scaphandre which runs as a daemon set which creates a pod on each node for collecting the metrics. The helm chart is not in a repo, it needs to be installed from the source code.

git clone https://github.com/hubblo-org/scaphandre
cd scaphandre
helm install scaphandre helm/scaphandre

Install Prometheus

Next we will install Prometheus which will scrape the metrics generated by Scaphandre.

helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
helm repo add kube-state-metrics https://kubernetes.github.io/kube-state-metrics
helm repo update

helm install prometheus prometheus-community/prometheus \
--set alertmanager.persistentVolume.enabled=false \
--set server.persistentVolume.enabled=false

This setup should only be used for testing as the Prometheus data is not persisted if the pods are deleted.

You can access the Prometheus web UI by creating a port forwarding connection.

kubectl port-forward deploy/prometheus-server 9090:9090

Install Grafana

Create a configmap to store the Grafana dashboard.

kubectl create configmap scaphandre-dashboard \

Install Grafana.

helm repo add grafana https://grafana.github.io/helm-charts
helm repo update

helm install grafana grafana/grafana --values docs_src/tutorials/grafana-helm-values.yaml

Get the Grafana web UI password which is randomly generated.

kubectl get secret grafana -o jsonpath="{.data.admin-password}" | base64 --decode

Create a port forwarding connection to the Grafana pod.

kubectl port-forward deploy/grafana 3000:3000

Open Grafana in your browser at http://localhost:3000 the username is admin.

Cleaning up

Deleting the Helm releases will remove all the resources we created.

helm delete grafana prometheus scaphandre
