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


Service monitor parameters

serviceMonitor.enabledCreate ServiceMonitor Resource for scraping metrics using PrometheusOperatorfalse
serviceMonitor.namespaceThe namespace in which the ServiceMonitor will be created (if not set, default to namespace on which this chart is installed)""
serviceMonitor.intervalThe interval at which metrics should be scraped1m

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
