# 🚀 Web Application with Docker, PostgreSQL & Flask
|
||||||
|
|
||||||
|
Простое веб-приложение с авторизацией, которое можно использовать как основу для собственного проекта.
|
||||||
|
|
||||||
|
## 🌟 Особенности проекта
|
||||||
|
|
||||||
|
- **Docker-ориентированный** (сборка через compose)
|
||||||
|
- **Безопасность**: секреты через ".env", healthcheck для БД
|
||||||
|
- **Автоматический деплой** через Git hooks
|
||||||
|
- **Логирование** операций деплоя
|
||||||
|
|
||||||
|
## 🛠 Технологический стек
|
||||||
|
|
||||||
|
- Frontend: Nginx со статическим html
|
||||||
|
- Backend: Python Flask
|
||||||
|
- DataBase: PostgreSQL
|
||||||
|
- Infrastructure: Docker, Docker Compose
|
||||||
|
- CI/CD: Git hooks

🔒 Безопасность
|
||||||
|
Все секреты хранятся в .env (в git не коммитятся)
|
||||||
|
|
||||||
|
Healthcheck для мониторинга состояния PostgreSQL
|
||||||
|
|
||||||
|
## CI/CD:
|
||||||
|
|
||||||
|
Автоматический деплой через Git hooks
|
||||||
|
|
||||||
|
Скрипт деплоя с логированием (/var/log/deploy.log)
|
||||||
|
|
||||||
|
## Infrastructure as Code:
|
||||||
|
|
||||||
|
Полная воспроизводимость через Docker
|
||||||
|
|
||||||
|
Версионирование образов
|
||||||
|
|
||||||
|
## 📈 Дальнейшее развитие
|
||||||
|
- Добавить тесты (pytest)
|
||||||
|
|
||||||
|
- Настроить GitHub Actions для CI
|
||||||
|
|
||||||
|
- Реализовать балансировку нагрузки
|
||||||
|
|
||||||
|
- Добавить мониторинг (Prometheus + Grafana)
