[gelluisaac]

Overview

Implement Docker containerization for the backend application.

Current State

• No Docker support
• Manual deployment
• Environment inconsistencies
• No containerization

Requirements

1. Docker Features

   • Dockerfile for backend
   • Docker Compose for local development
   • Multi-stage builds
   • Image optimization
   • Security scanning

2. Container Configuration

   • Environment variables
   • Volume mounts
   • Network configuration
   • Health checks
   • Resource limits

3. Development Workflow

   • Local development with Docker
   • Hot reload in containers
   • Database in container
   • Redis in container
   • Easy setup

4. Production Ready

   • Production Dockerfile
   • Image registry
   • Image tagging
   • Security best practices
   • Documentation

Technical Details

• Create Dockerfile
• Create docker-compose.yml
• Optimize image size
• Add health checks

Files to Create/Modify

• backend/Dockerfile (create)
• backend/Dockerfile.dev (create)
• backend/docker-compose.yml (create)
• backend/.dockerignore (create)
• backend/docker-compose.prod.yml (create)

Acceptance Criteria

• Docker image builds successfully
• Docker Compose works locally
• Hot reload works
• Production image is optimized
• Health checks work
• Security scanning passes
• Documentation is complete
• Image size is optimized
