+# React + TypeScript + Vite
+
+This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
+
+Currently, two official plugins are available:
+
+- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react/README.md) uses [Babel](https://babeljs.io/) for Fast Refresh
+- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react-swc) uses [SWC](https://swc.rs/) for Fast Refresh
+
+## Expanding the ESLint configuration
+
+If you are developing a production application, we recommend updating the configuration to enable type aware lint rules:
+
+- Configure the top-level `parserOptions` property like this:
+
+```js
+export default tseslint.config({
+  languageOptions: {
+    // other options...
+    parserOptions: {
+      project: ['./tsconfig.node.json', './tsconfig.app.json'],
+      tsconfigRootDir: import.meta.dirname,
+    },
+  },
+})
+```
+
+- Replace `tseslint.configs.recommended` to `tseslint.configs.recommendedTypeChecked` or `tseslint.configs.strictTypeChecked`
+- Optionally add `...tseslint.configs.stylisticTypeChecked`
+- Install [eslint-plugin-react](https://github.com/jsx-eslint/eslint-plugin-react) and update the config:
+
+```js
+// eslint.config.js
+import react from 'eslint-plugin-react'
+
+export default tseslint.config({
+  // Set the react version
+  settings: { react: { version: '18.3' } },
+  plugins: {
+    // Add the react plugin
+    react,
+  },
+  rules: {
+    // other rules...
+    // Enable its recommended rules
+    ...react.configs.recommended.rules,
+    ...react.configs['jsx-runtime'].rules,
+  },
+})
+```

+# Expense Tracker - Kubernetes Deployment
+
+## Описание приложения
+
+Expense Tracker - это веб-приложение для отслеживания личных финансов и управления расходами. Приложение позволяет пользователям:
+- Добавлять новые транзакции с указанием суммы, типа (доход/расход) и категории
+- Просматривать историю транзакций
+- Анализировать расходы по категориям
+- Отслеживать баланс счета
+
+## Архитектура приложения
+
+Приложение построено на стеке MERN (MongoDB, Express.js, React, Node.js) и состоит из трех основных компонентов:
+
+1. **Frontend** - клиентская часть, разработанная на React с использованием Vite для быстрой сборки
+2. **Backend** - серверная часть, разработанная на Node.js с использованием Express.js
+3. **MongoDB** - база данных для хранения информации о транзакциях
+
+## Список использованных контейнеров
+
+1. **expense-tracker-frontend** - контейнер с клиентской частью приложения
+   - Базовый образ: node:20-bookworm-slim
+   - Роль: Обслуживает пользовательский интерфейс приложения
+   - Порт: 5173
+
+2. **expense-tracker-backend** - контейнер с серверной частью приложения
+   - Базовый образ: node:20-bookworm-slim
+   - Роль: Предоставляет API для работы с данными о транзакциях
+   - Порт: 5000
+
+3. **mongo** - контейнер с базой данных MongoDB
+   - Базовый образ: mongo:latest
+   - Роль: Хранение данных приложения
+   - Порт: 27017
+
+## Kubernetes объекты и их описание
+
+1. **Namespace**
+   - Имя: expense-tracker
+   - Роль: Изолированное пространство имен для всех ресурсов приложения
+
+2. **Deployment**
+   - Frontend Deployment: Управляет репликами Pod с клиентской частью приложения
+   - Backend Deployment: Управляет репликами Pod с серверной частью приложения
+
+3. **StatefulSet**
+   - MongoDB StatefulSet: Управляет Pod с базой данных MongoDB, сохраняя состояние и данные
+
+4. **Service**
+   - Frontend Service (NodePort): Предоставляет доступ к клиентской части приложения извне кластера
+   - Backend Service (ClusterIP): Обеспечивает внутрикластерный доступ к API
+   - MongoDB Service (ClusterIP): Обеспечивает внутрикластерный доступ к базе данных
+
+5. **PersistentVolume и PersistentVolumeClaim**
+   - MongoDB PV/PVC: Обеспечивает постоянное хранилище для данных MongoDB
+
+## Сетевая инфраструктура
+
+Приложение использует следующие сетевые ресурсы:
+
+1. **Services**
+   - Frontend Service (NodePort): Доступен извне кластера через порт, назначаемый Kubernetes (30000-32767)
+   - Backend Service (ClusterIP): Доступен внутри кластера по имени `backend-service:5000`
+   - MongoDB Service (ClusterIP): Доступен внутри кластера по имени `mongodb-service:27017`
+
+2. **Внутрикластерная DNS-система**
+   - Позволяет компонентам приложения обращаться друг к другу по именам сервисов вместо IP-адресов
+
+## Хранилища данных
+
+Приложение использует постоянное хранилище для базы данных MongoDB:
+
+1. **PersistentVolume**
+   - Тип: HostPath (для локальной разработки)
+   - Размер: 1Gi
+   - Путь на хосте: `/mnt/data/mongodb`
+
+2. **PersistentVolumeClaim**
+   - Запрашивает 1Gi постоянного хранилища для MongoDB
+
+## Конфигурация контейнеров
+
+1. **Frontend**
+   - Environment: Для разработки используется Vite Dev Server с опцией `--host` для доступа извне
+   - Ресурсы: Лимиты CPU: 0.5, Memory: 512Mi; Запросы CPU: 0.2, Memory: 256Mi
+
+2. **Backend**
+   - Environment: 
+     - PORT: 5000
+     - MONGO_URI: mongodb://mongodb-service:27017/expense-tracker
+   - Ресурсы: Лимиты CPU: 0.5, Memory: 512Mi; Запросы CPU: 0.2, Memory: 256Mi
+
+3. **MongoDB**
+   - Без дополнительной конфигурации, используется стандартный образ
+   - Данные хранятся в постоянном хранилище
+   - Ресурсы: Лимиты CPU: 0.5, Memory: 512Mi; Запросы CPU: 0.2, Memory: 256Mi
+
+## Инструкция по запуску
+
+### Предварительные требования
+
+1. Установленный и настроенный Kubernetes кластер (можно использовать Minikube для локальной разработки)
+2. Установленный и настроенный kubectl
+3. Docker
+
+### Подготовка приложения
+
+1. Выполните скрипт подготовки:
+   ```bash
+   chmod +x prepare-app.sh
+   ./prepare-app.sh
+   ```
+
+   Скрипт выполнит следующие действия:
+   - Создаст директорию для хранения данных MongoDB
+   - Соберет Docker-образы для Frontend и Backend
+
+### Запуск приложения
+
+1. Выполните скрипт запуска:
+   ```bash
+   chmod +x start-app.sh
+   ./start-app.sh
+   ```
+
+   Скрипт выполнит следующие действия:
+   - Создаст Namespace expense-tracker
+   - Применит все конфигурационные файлы Kubernetes
+   - Дождется запуска всех компонентов
+   - Выведет URL для доступа к приложению
+
+### Остановка приложения
+
+1. Для остановки приложения выполните:
+   ```bash
+   chmod +x stop-app.sh
+   ./stop-app.sh
+   ```
+
+   Скрипт выполнит следующие действия:
+   - Удалит все развернутые в Kubernetes ресурсы приложения
+
+### Доступ к приложению
+
+После успешного запуска вы получите URL для доступа к приложению в выводе скрипта start-app.sh. Обычно это будет что-то вроде:
+```
+http://192.168.49.2:30080
+```
+
+где:
+- 192.168.49.2 - IP-адрес узла кластера (для Minikube это IP-адрес виртуальной машины)
+- 30080 - назначенный NodePort для Frontend-сервиса
+
+## Дополнительная информация
+
+- Для просмотра всех ресурсов в пространстве имен expense-tracker:
+  ```bash
+  kubectl get all -n expense-tracker
+  ```
+
+- Для просмотра логов компонентов:
+  ```bash
+  kubectl logs deployment/frontend -n expense-tracker
+  kubectl logs deployment/backend -n expense-tracker
+  kubectl logs statefulset/mongodb -n expense-tracker
+  ```
+
+- Для доступа к оболочке контейнеров:
+  ```bash
+  kubectl exec -it deployment/frontend -n expense-tracker -- sh
+  kubectl exec -it deployment/backend -n expense-tracker -- sh
+  kubectl exec -it statefulset/mongodb -n expense-tracker -- sh
+  ```
