🚀 DevOps Capstone Project

This project demonstrates the implementation of a complete DevOps lifecycle including infrastructure provisioning, configuration management, CI/CD pipeline, and containerization.

---

📌 Project Overview

The goal of this project is to automate the deployment of a web application using DevOps tools and best practices. The system provisions infrastructure, configures nodes, builds and deploys applications, and ensures continuous integration and delivery.

---

🛠️ Tools & Technologies Used

• AWS EC2
• Terraform (Infrastructure as Code)
• Ansible (Configuration Management)
• Jenkins (CI/CD Pipeline)
• Docker (Containerization)
• GitHub (Version Control)

---

⚙️ Project Architecture

1. Infrastructure Setup

• Provisioned multiple EC2 instances using Terraform
• Created separate nodes for:
  • Jenkins Server
  • Application Server(s)

---

2. Configuration Management

• Used Ansible to:
  • Install required software on all nodes
  • Configure environments automatically

---

3. CI/CD Pipeline

• Implemented a Jenkins Pipeline to:
  • Clone code from GitHub
  • Build Docker image
  • Deploy application container
• Pipeline triggers automatically on code push

---

4. Containerization

• Application is containerized using Docker
• Used base image: hshar/webapp forked
• Application code is deployed to: /var/www/html

---

🔄 Workflow

1. Developer pushes code to GitHub
2. Jenkins pipeline is triggered
3. Docker image is built using Dockerfile
4. Container is deployed to the application server
5. Updated application goes live automatically

---

The following were captured and documented:

• ✅ Nodes created and configured
• ✅ Infrastructure setup using Terraform
• ✅ Ansible execution logs
• ✅ Jenkins pipeline stages
• ✅ Console output of builds
• ✅ Code changes tracking
