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

Developer pushes code to Gitea
Jenkins webhook triggers the pipeline
SonarQube scans code for quality compliance
Docker image is built from approved code
Image is pushed to Artifactory registry
Terraform provisions/updates AWS infrastructure
Ansible configures EC2 instances for ECS
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
