+# **🛡️ DevSecOps Automation Pipeline**
+
+## **📖 Project Overview**
+
+This repository demonstrates a comprehensive **DevSecOps implementation** assigned as part of the advanced cloud computing curriculum. The project automates the lifecycle of a secure Node.js application—from code commit to production deployment—integrating **Continuous Integration (CI)**, **Continuous Security**, and **Continuous Deployment (CD)**.
+
+The pipeline is executed on a **Self-Hosted Runner**, ensuring full control over the build environment, and deploys to a local **Kubernetes (Minikube)** cluster.
+
+## **🏗️ Architecture & Workflow**
+
+The pipeline follows a strict **"Shift-Left" Security** approach, ensuring vulnerabilities are caught before deployment.

+
+### **Pipeline Stages**
+
+1. **Semantic Versioning:** Automatically determines the next version tag (e.g., v1.0.1) based on commit messages.  
+2. **Containerization:** Builds a lightweight, optimized Docker image for the Node.js application.  
+3. **Vulnerability Scanning:** Uses **Trivy** to scan the image for CRITICAL and HIGH CVEs. *The build fails immediately if risks are detected.*  
+4. **Artifact Management:** Securely pushes the verified image to the **GitHub Container Registry (GHCR)**.  
+5. **Kubernetes Deployment:** Updates the deployment manifest and performs a rolling update on the Minikube cluster.
+
+## **🛠️ Technology Stack**
+
+| Component | Technology | Description |
+| :---- | :---- | :---- |
+| **Source Control** |  | Version control and repository management. |
+| **CI/CD** |  | Automates the build, scan, and deploy workflow. |
+| **Containerization** |  | Container runtime and image building. |
+| **Orchestration** |  | Manages containerized application deployment. |
+| **Security** |  | Scans container images for security vulnerabilities. |
+| **Backend** |  | Lightweight Express.js application. |
+| **Environment** |  | Hosting environment for the Self-Hosted Runner. |
+
+## **🚀 Getting Started**
+
+To replicate this environment locally, follow these steps.
+
+### **1\. Prerequisites**
+
+Ensure your environment (VM or Local Machine) has the following installed:
+
+* Docker & Docker Compose  
+* Minikube  
+* Kubectl  
+* Git
+
+### **2\. Installation**
+
+\# Clone the repository  
+git clone \[https://github.com/RoshaneAnees/devsecops.git\](https://github.com/RoshaneAnees/devsecops.git)  
+cd devsecops
+
+\# Start Minikube  
+minikube start \--driver=docker
+
+\# Check Cluster Status  
+kubectl get nodes
+
+### **3\. Deployment**
+
+The deployment is handled automatically by the GitHub Actions pipeline. However, you can apply manifests manually for testing:
+
+kubectl apply \-f k8s/
+
+## **🔒 Security Implementation**
+
+Security is the core component of this project. The pipeline integrates **Aqua Security's Trivy** scanner.
+
+* **Scanned Target:** ghcr.io/roshaneanees/devsecops-app:latest  
+* **Severity Threshold:** CRITICAL, HIGH  
+* **Action:** If any vulnerability matching these severities is found, the pipeline **halts immediately**, preventing insecure code from reaching production.
+
+## **🌐 Accessing the Application**
+
+Once the pipeline completes successfully:
+
+1. **Verify the Pods are running:**  
+   kubectl get pods
+
+2. **Access the Service:**  
+   \# Get the URL directly from Minikube  
+   minikube service devsecops-svc \--url
+
+3. **Port Forwarding (Alternative):**  
+   kubectl port-forward svc/devsecops-svc 3000:3000
+
+   Visit http://localhost:3000 in your browser.
