# 🚀 Monitoring Kubernetes with Prometheus and Grafana on Minikube
## 🔥 Introduction
Kubernetes is a powerful orchestration tool, but monitoring its performance is crucial for ensuring smooth operations. This is where **Prometheus** and **Grafana** come into play. Prometheus is a leading open-source monitoring solution, while Grafana is a visualization tool that helps make sense of the collected data.
In this guide, we’ll walk through setting up **Prometheus and Grafana on Minikube**, a local Kubernetes cluster, to monitor and visualize cluster metrics. This tutorial is **beginner-friendly** and will help you get hands-on experience with Kubernetes monitoring.
---
## ✅ Prerequisites
Before we start, ensure you have the following installed:
- **Minikube** ([Install Guide](https://minikube.sigs.k8s.io/docs/start/))
- **kubectl** ([Install Guide](https://kubernetes.io/docs/tasks/tools/))
- **Helm** ([Install Guide](https://helm.sh/docs/intro/install/))
To verify Minikube is installed, run:
```sh
minikube version
```
---
## ⚙️ Step 1: Start Minikube
First, start your Minikube cluster:
```sh
minikube start
```
Check the status:
```sh
minikube status
```
---
## 📦 Step 2: Create a Namespace for Monitoring
It's a good practice to keep monitoring components in a separate namespace.
```sh
kubectl create namespace monitoring
```
---
## 📡 Step 3: Deploy Prometheus
1️⃣ Add the **Prometheus Helm repository**:
```sh
helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
helm repo update
```
2️⃣ Install **Prometheus**:
```sh
helm install prometheus prometheus-community/prometheus -n monitoring
```
3️⃣ Verify the installation:
```sh
kubectl get pods -n monitoring
```
4️⃣ Check the running ports of the Prometheus pod:
```sh
kubectl describe pod -n monitoring
```
5️⃣ Expose the Prometheus service:
```sh
kubectl expose service prometheus-server --type=NodePort --target-port=9090 --name=prometheus-server-exp -n monitoring
```
6️⃣ Verify the exposed service:
```sh
kubectl get svc -n monitoring
```
7️⃣ Access Prometheus in the browser:
```sh
minikube service prometheus-server-exp -n monitoring
```
---
## 📊 Step 4: Deploy Grafana
1️⃣ Add the **Grafana Helm repository**:
```sh
helm repo add grafana https://grafana.github.io/helm-charts
```
2️⃣ Install **Grafana**:
```sh
helm install grafana grafana/grafana -n monitoring
```
3️⃣ Get the default Grafana admin password:
```sh
kubectl get secret --namespace monitoring grafana -o jsonpath="{.data.admin-password}"
```
🔑 Decode the base64-encoded password using a third-party tool or command-line utility.
4️⃣ Check the running ports of the Grafana pod:
```sh
kubectl describe pod -n monitoring
```
5️⃣ Expose the Grafana service:
```sh
kubectl expose service grafana --type=NodePort --target-port=3000 --name=grafana-exp -n monitoring
```
6️⃣ Access Grafana in the browser:
```sh
minikube service grafana-exp -n monitoring
```
---
## 🛠️ Step 5: Add Prometheus as a Data Source in Grafana
1️⃣ In Grafana, navigate to **Settings → Data Sources → Add Data Source**.
2️⃣ Select **Prometheus**.
3️⃣ Use the following URL:
```
http://:
```
4️⃣ Click **Save & Test** to confirm the connection.
---
## 📈 Step 6: Import Kubernetes Dashboards in Grafana
Grafana provides pre-built dashboards for Kubernetes monitoring:
1️⃣ Go to **Dashboards → Import**.
2️⃣ Enter **Dashboard ID:** `3662`.
3️⃣ Select the Prometheus data source and click **Import**.
You should now see real-time metrics from your Minikube cluster! As shown below🎉
---
## 🎯 Conclusion
Congratulations! You have successfully set up **Prometheus and Grafana on Minikube**. You can now:
- Monitor **CPU, memory, and network usage**.
- Visualize real-time metrics with **Grafana dashboards**.
- Set up **alerts** using Alertmanager.
To further improve your monitoring setup, consider configuring **Alertmanager** for notifications and exploring **custom dashboards**.
🚀 **Next Steps**:
- Learn more about **Prometheus Query Language (PromQL)**.
- Customize Grafana dashboards to fit your needs.
- Set up monitoring for real-world Kubernetes clusters using **kube-prometheus**.
