Containerization of the application which include complete project setup

[inzamrzn918]

🧩 Task

• Create optimized Dockerfiles for both frontend and backend services.
• Develop a Docker Compose file to build and run the entire project stack.
• Ensure all modules and dependent services (e.g., database, cache, message broker, etc.) are included and properly networked.

---

🧠 Context

We want to containerize the full application for consistent deployment across environments.
The setup should support both local development and production builds, focusing on performance, security, and scalability.

---

✅ Acceptance Criteria

• Dockerfiles are multi-stage builds optimized for:
  • Faster build time
  • Minimal image size
  • Lower memory and CPU usage
• Security best practices are implemented:
  • Use non-root user where possible
  • Use verified base images (e.g., node:alpine)
  • Run security scan (docker scout, trivy, etc.)
• Docker Compose setup allows:
  • Running all services with a single docker-compose up
  • Easy environment configuration via .env
  • Automatic restart policies for critical services
• CI/CD pipeline compatibility (build & push images)

---

🧪 Testing & Verification

• Verify all containers start successfully without errors.
• Test inter-service communication (e.g., backend ↔ database, frontend ↔ API).
• Validate image sizes and build time improvements.
• Perform a basic vulnerability scan before merging.

---

📦 Deliverables

• frontend/Dockerfile
• backend/Dockerfile
• docker-compose.yml
• .env.example file with necessary configuration keys
