Prometheus

Let's see how to run Prometheus (code) in a Kubernetes cluster.

Configuration

We'll use the community Helm chart (code):

• values.yaml

Deployment

# adds Helm chart repository
helm repo add prometheus-community  https://prometheus-community.github.io/helm-charts
helm repo update

# installs
helm upgrade --install prometheus prometheus-community/prometheus --namespace prometheus --create-namespace

# checks everything is ok
kubectl get pod -n prometheus

# uninstalls
helm uninstall prometheus -n prometheus
kubectl delete ns prometheus

Examples

Minimal installation with default parameters

Install the application:

helm upgrade --install prometheus prometheus-community/prometheus --namespace prometheus --create-namespace

Forward the service port for local access:

kubectl port-forward service/prometheus-server 9090:80 -n prometheus

Open in a browser localhost:9090
