To quickly start all the things just do this:
kubectl create namespace monitoring
kubectl --namespace monitoring create \
--filename https://raw.githubusercontent.com/giantswarm/kubernetes-prometheus/master/manifests-all.yamlTo shut down all components again:
kubectl delete namespace monitoringAlternatively follow these steps to get a feeling for the different components of this setup:
kubectl create --filename manifests/prometheus-core-configmap.yaml
# kubectl get configmaps
# kubectl delete configmaps/prometheus
kubectl create --filename manifests/prometheus-core-service.yaml
# kubectl get services/prometheus
# minikube service prometheus
kubectl create --filename manifests/prometheus-core-deployment.yaml
# kubectl get --all-namespaces --output wide pods
# kubectl logs prometheus-2556266794-sd260
# kubectl delete pods/prometheus-2556266794-sd260
kubectl create --filename manifests/node-exporter-service.yaml
kubectl create --filename manifests/node-exporter-daemonset.yaml
# create Alertmanager
kubectl create --filename manifests/prometheus-alert-configmap.yaml
kubectl create --filename manifests/prometheus-alert-service.yaml
kubectl create --filename manifests/prometheus-alert-deployment.yaml
kubectl create --filename manifests/grafana-service.yaml
# kubectl get services/grafana
# minikube service grafana
kubectl create --filename manifests/grafana-deployment.yaml
# kubectl get --all-namespaces --output wide podsSee grafana.net for some example dashboards and plugins.

Configure Prometheus data source for Grafana.
Grafana UI / Data Sources / Add data sourceName:prometheusType:PrometheusUrl:http:https://prometheus:9090Add
-
Import Prometheus Stats:

-
Import Kubernetes cluster monitoring:

Instead of manually configuring the datasource and dashboards you can run the following job. It uses the API to configure Grafana to a state similar to when you manually go through the steps described above.
kubectl create --filename manifests/grafana-import-dashboards-job.yamltarget="./manifests-all.yaml"
rm "$target"
printf -- "# Derived from ./manifests/*.yaml\n---\n" >> "$target"
for file in ./manifests/*.yaml ; do
if [ -e "$file" ] ; then
cat "$file" >> "$target"
printf -- "---\n" >> "$target"
fi
done
