+# AWS ECS CI/CD Pipeline with Terraform, Ansible & Jenkins
+
+A complete CI/CD pipeline for deploying microservices to AWS ECS using infrastructure as code and configuration management.
+
+## 🚀 Overview
+
+This project implements an end-to-end CI/CD pipeline that automates the build, test, and deployment of microservices to AWS ECS. The pipeline leverages DevOps best practices to create a reproducible, scalable deployment solution optimized for AWS Free Tier.
+
+## 🛠️ Technology Stack
+
+- **Terraform** - Provisions all AWS infrastructure
+- **Ansible** - Configures EC2 instances with Docker and ECS agent
+- **Jenkins** - Orchestrates the entire CI/CD workflow
+- **Artifactory** - Hosts Docker images
+- **SonarQube** - Enforces code quality gates
+- **Gitea** - Git repository hosting
+- **AWS ECS** - Container orchestration (EC2-backed)
+
+## 📋 Pipeline Workflow
+
+1. Developer pushes code to Gitea
+2. Jenkins webhook triggers the pipeline
+3. SonarQube scans code for quality compliance
+4. Docker image is built from approved code
+5. Image is pushed to Artifactory registry
+6. Terraform provisions/updates AWS infrastructure
+7. Ansible configures EC2 instances for ECS
+8. Microservice is deployed to ECS cluster
+
+## 🏗️ Infrastructure Components
+
+### AWS Resources (Managed by Terraform)
+- VPC with public/private subnets
+- ECS cluster with EC2 container instances
+- Application Load Balancer (ALB)
+- Security groups and IAM roles
+- Auto-scaling capabilities
+
+### DevOps Tools (Self-hosted)
+All DevOps tools run on a dedicated Linux server:
+- Jenkins for CI/CD automation
+- Gitea for version control
+- SonarQube for code analysis
+- Artifactory for artifact management
