+
+## 📖 Project Overview
+
+This repository demonstrates a **complete DevSecOps automation pipeline** developed as part of an **Advanced Cloud Computing course**.
+
+The project automates the entire lifecycle of a **Node.js application** — from source code commit to secure deployment — while enforcing **security at every stage** using a **Shift-Left DevSecOps approach**.
+
+The pipeline runs on a **Self-Hosted GitHub Actions Runner** and deploys the application to a **local Kubernetes cluster (Minikube)**.
+
+---
+
+## 🎯 What We Achieved
+
+✔ Fully automated CI/CD pipeline  
+✔ Integrated security scanning (DevSecOps)  
+✔ Containerized application delivery  
+✔ Kubernetes-based deployment  
+✔ Real-world cloud-native workflow
+

+
+## 🏗️ Architecture & Workflow

+```
+
+---
+
+## 🔄 Pipeline Stages Explained
+
+1. **Source Code Commit**  
+   Developer pushes code to GitHub.
+
+2. **Semantic Versioning**  
+   Automatically generates version tags (e.g. `v1.0.1`) based on commit history.
+
+3. **Docker Image Build**  
+   Builds a lightweight and optimized container image.
+
+4. **Security Scanning (Trivy)**  
+   - Scans image for **CRITICAL** and **HIGH** vulnerabilities  
+   - Pipeline **fails immediately** if vulnerabilities are detected
+
+5. **Image Registry (GHCR)**  
+   Securely pushes verified images to **GitHub Container Registry**.
+
+6. **Kubernetes Deployment**  
+   Performs rolling updates on **Minikube** using Kubernetes manifests.

+
+## 🚀 Getting Started
+
+### ✅ Prerequisites
+
+Ensure the following tools are installed:
+
+- Docker  
+- Minikube  
+- kubectl  
+- Git
+
+---
+
+### 📥 Installation
+
+```bash
+# Clone the repository
+git clone https://github.com/RoshaneAnees/devsecops.git
+cd devsecops
+
+# Start Minikube
+minikube start --driver=docker
+
+# Verify cluster
+kubectl get nodes
+```
+
+---
+
+### 🚢 Deployment
+
+Deployment is **fully automated** via GitHub Actions.
+
+For manual testing:
+
+```bash
+kubectl apply -f k8s/
+```
+
+---
+
+## 🔒 Security Implementation (DevSecOps Core)
+
+Security is **embedded**, not optional.
+
+- 🔍 **Scanner:** Trivy (Aqua Security)
+- 🎯 **Target:** Docker image
+- 🚨 **Severity Gate:** CRITICAL & HIGH
+- ⛔ **Policy:** Pipeline stops on detection
+
+This ensures **no vulnerable container reaches production**.
+
+---
+
+## 🌐 Accessing the Application
+
+### Check Pod Status
+
+```bash
+kubectl get pods
+```
+
+### Access via Minikube
+
+```bash
+minikube service devsecops-svc --url
+```
+
+### Port Forward (Alternative)
+
+```bash
+kubectl port-forward svc/devsecops-svc 3000:3000
+```
+
+Visit:  
+👉 **http://localhost:3000**
