☁️ Cloud DevOps Project — AWS + Terraform + Docker + CI/CD

This project demonstrates a modern DevOps workflow where infrastructure is provisioned on AWS using Terraform and application delivery is automated through CI/CD pipelines.

Every push to the main branch automatically:

• Builds a Docker image
• Pushes the image to Amazon ECR
• Makes the latest container available for deployment on AWS EC2

---

🧱 Architecture

• ☁️ AWS EC2 (Ubuntu)
• 🐳 Docker
• 🏗️ Terraform
• ⚙️ GitHub Actions
• 📦 Amazon ECR
• 🔐 IAM Roles
• 🖥️ AWS Systems Manager (SSM)

---

🛠️ Tech Stack

• Python (Flask)
• Docker
• Terraform
• GitHub Actions
• AWS EC2
• AWS ECR
• AWS IAM
• AWS SSM
