🐳 DevOps Infrastructure Implementation Summary

✅ Что реализовано

1. Docker Containerization

• Dockerfile с multi-stage build для оптимизации размера
• Security: непривилегированный пользователь, health checks
• Optimization: layer caching, минимальный базовый образ

2. Docker Compose Setup

• Development: docker-compose.yml с auto-rebuild и volume mounting
• Production: docker-compose.prod.yml с persistent volumes и restart policies
• Resource limits: CPU/Memory ограничения для stability

3. CI/CD Pipeline (Drone)

• 9-stage pipeline: lint → test → security → build → test-docker → deploy
• Branch-based deployment:
  • develop → staging environment
  • main → production environment
• Security scanning: Safety + Bandit для проверки уязвимостей
• Notifications: Webhook уведомления о результатах

4. Automation Scripts

• scripts/dev.sh: Development workflow automation
• scripts/deploy.sh: Production deployment и monitoring
• Extended Makefile: Unified command interface

5. Configuration Management

• Environment templates: .env.example, .env.prod.example
• Gitignore updates: Docker и CI/CD файлы
• Secret management: Drone secrets для токенов

6. Documentation

• DOCKER_README.md: Comprehensive Docker/CI/CD guide
• INFRASTRUCTURE.md: Project structure и components overview
• DEVOPS_SUMMARY.md: Implementation summary (this file)
