+# Кашин Максим ПИбд-42
+
+# Проект "Университеты и Факультеты"
+
+## Часть 1: Создание Docker
+
+### Установка Docker и Docker Compose
+Перед началом нужно проверить, что Docker работает, иначе использовать инструцию для 1-ой лабораторной.
+
+### 1.1 Файл `docker-compose.yml`
+В корне проекта файл `docker-compose.yml`. Этот файл будет описывать, как должны быть организованы сервисы. В данном случае рассматриваем только университет, в факультетах анологично.
+
+```yaml
+version: '3.8'
+services:
+  university_service:
+    build:
+      context: ./university_service
+    depends_on:
+      - university_db
+    environment:
+      - FLASK_APP=app.py
+    expose:
+      - 8081
+  university_db:
+    image: postgres:13
+    environment:
+      POSTGRES_USER: university_user
+      POSTGRES_PASSWORD: password
+      POSTGRES_DB: universitydb
+    ports:
+      - "5432:5432"
+```
+
+Объяснение:
+- `version`: Указывает версию Docker Compose.
+- `services`: Определяет микросервисы. В данном случае, мы начинаем с `university_service`.
+- `build`: Указывает, что нужно построить образ для этого сервиса, используя Dockerfile из указанной директории.
+- `depends_on`: Указывает, что этот сервис зависит от `university_db` (базы данных), которая будет запущена первой.
+- `environment`: Определяет переменные окружения для сервиса, в данном случае указывая файл Flask.
+- `expose`: Указывает, что сервис будет доступен на порту 8081 внутри Docker-сети.
+
+### 1.2 Файл Dockerfile для сервиса университетов
+В каталоге `university_service` файл `Dockerfile`. Этот файл будет содержать инструкции для сборки образа сервиса университетов. В данном случае рассматриваем только университет, в факультетах анологично.
+
+```dockerfile
+FROM python:3.9-slim
+
+# Установка зависимостей
+RUN apt-get update && apt-get install -y \
+    gcc \
+    libpq-dev \
+    && rm -rf /var/lib/apt/lists/*
+
+# Установка рабочей директории
+WORKDIR /app
+
+# Копирование файлов
+COPY requirements.txt requirements.txt
+
+# Установка Python-зависимостей
+RUN pip install --no-cache-dir -r requirements.txt
+
+# Копирование всех файлов приложения
+COPY . .
+
+# Запуск приложения
+CMD ["python", "app.py"]
+```
+
+
+### 1.3 Создание файла requirements.txt
+В каталоге `university_service` файл `requirements.txt`, в котором перечислите все необходимые библиотеки для приложения. В данном случае рассматриваем только университет, в факультетах анологично.
+
+```txt
+flask
+flask_sqlalchemy
+psycopg2
+```
+
+### 1.5 Запуск Docker Compose
+Когда все файлы созданы, можно запустить сервисы с помощью команды:
+
+```bash
+docker-compose up
+```
+
+Эта команда создаст и запустит все указанные в `docker-compose.yml` сервисы.
+
+## Часть 2: Реализация функциональности
+
+### 2.1 Создание сервиса для университетов
+В каталоге `university_service` файл `app.py`,`service.py`,`db.py`. Этb файлы будут содержать код Flask приложения для управления университетами и базы данных для него.
+
+### 2.2 Создание сервиса для факультетов
+Каталог `faculty_service` и в нем файл `app.py`,`service.py`,`db.py`. Эти файлы будут содержать код для управления факультетами и базы данных для него.
+
+### 2.3 Создание таблиц базы данных
+Нужно создать таблицы базы данных для университетов и факультетов. Для этого созданы файлы init.sql для университета и для факультетов.
+
+### 2.4 Тестирование API
+Тестирование производится через расширение RestMan. В нем мы можем убедиться, что весь CRUD работает исправно.
+
