# Prometheus and Grafana Installation Using Helm Charts
This guide explains how to install Prometheus and Grafana in a Kubernetes cluster using Helm charts.
## Prerequisites
Before you begin, ensure the following:
1. A running Kubernetes cluster.
2. `kubectl` CLI installed and configured.
3. Helm CLI installed (version 3 or later).
## Step 1: Add Helm Repositories
Add the Prometheus and Grafana Helm chart repositories:
```bash
helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
helm repo add grafana https://grafana.github.io/helm-charts
helm repo update
```
## Step 2: Install Prometheus
1. Create a dedicated namespace for monitoring components:
```bash
kubectl create namespace monitoring
```
2. Install Prometheus using the `kube-prometheus-stack` Helm chart:
```bash
helm install prometheus prometheus-community/kube-prometheus-stack \
--namespace monitoring
```
3. Verify the Prometheus installation:
```bash
kubectl get pods -n monitoring
```
## Step 3: Install Grafana
1. Install Grafana in the same namespace:
```bash
helm install grafana grafana/grafana \
--namespace monitoring
```
2. Verify the Grafana installation:
```bash
kubectl get pods -n monitoring
```
3. Retrieve the Grafana admin password:
```bash
kubectl get secret grafana -n monitoring -o jsonpath="{.data.admin-password}" | base64 --decode
```
The default username is `admin`.
## Step 4: Access Prometheus and Grafana
1. **Prometheus**:
- Forward the Prometheus service port:
```bash
kubectl port-forward svc/prometheus-kube-prometheus-prometheus -n monitoring 9090:9090
```
- Open your browser and navigate to `http://localhost:9090`.
2. **Grafana**:
- Forward the Grafana service port:
```bash
kubectl port-forward svc/grafana -n monitoring 3000:80
```
- Open your browser and navigate to `http://localhost:3000`.
## Step 5: Configure Grafana
1. Login to Grafana using the admin credentials retrieved earlier.
2. Add Prometheus as a data source:
- Navigate to **Configuration → Data Sources → Add Data Source**.
- Select **Prometheus**.
- Set the URL to `http://prometheus-kube-prometheus-prometheus.monitoring.svc.cluster.local:9090`.
- Click **Save & Test**.
3. Import Prebuilt Dashboards:
- Go to **Create → Import**.
- Enter the Dashboard ID from [Grafana's Dashboard Library](https://grafana.com/grafana/dashboards/).
- Example: Use Dashboard ID `315` for Kubernetes cluster monitoring.
## Step 6: Uninstall (Optional)
To uninstall Prometheus and Grafana:
1. Uninstall Prometheus:
```bash
helm uninstall prometheus -n monitoring
```
2. Uninstall Grafana:
```bash
helm uninstall grafana -n monitoring
```
3. Delete the monitoring namespace:
```bash
kubectl delete namespace monitoring
```
## Notes
- Ensure sufficient resources are allocated to your Kubernetes cluster for running Prometheus and Grafana.
- Use PersistentVolumes if you need long-term data storage for Prometheus or Grafana configurations.
- Secure Grafana with Single Sign-On (SSO) or by enabling HTTPS for production use.
