+# Отчет. Лабораторная работа 3
+
+## Описание
+В рамках лабораторной работы № 3 были реализованы два сервиса (Java + Spring), осуществляющие CRUD-операции над сущностями. 
+
+Модель данных следующая:
+
+Сущность "Компания" (сервис company)
+- идентификатор компании
+- название
+- адрес
+
+Сущность "Вакансия" (сервис vacancy)
+- идентификатор вакансии
+- название
+- описание
+- нижняя граница зарплаты
+- верхняя граница зарплаты
+- идентификатор компании
+
+Компания с вакансией связана как "один ко многим".
+
+Каждый из сервисов имеет API с пятью эндпоинтами. При этом в сервисе vacancy при запросе вакансии по id происходит 
+дополнительный запрос в сервис company для получения информации по компании, связанной с вакансией. 
+Происходит это взаимодействие с помощью библиотеки OpenFeign, которая "под капотом" использует HttpClient. 
+
+В качестве хранилища данных использовалась СУБД Postgres. У каждого сервиса своя база данных в поднятой СУБД. 
+Для создания схемы БД была использована библиотека Flyway, которая применила написанные миграции при старте приложения.
+
+Запросы к сервисам проксирует шлюз на основе Nginx. Для этого перед запуском nginx был описан конфигурационный файл nginx.conf, 
+в котором описан прослушиваемый порт и название сервера (в блоке server), маршруты до микросервисов и параметры проксирования (в блоке location).
+
+Таким образом, с помощью Docker Compose были подняты сервисы:
+- company
+- vacancy
+- postgres
+- nginx
+## Как запустить
+Для того, чтобы запустить сервисы, необходимо выполнить следующие действия:
+1. Установить и запустить Docker Engine или Docker Desktop
+2. Через консоль перейти в папку, в которой расположен файл docker-compose.yml
+3. Выполнить команду:
+```
+docker compose up --build
+```
+В случае успешного запуска всех контейнеров в консоли будет выведено следующее сообщение:
+```
+[+] Running 5/5
+ ✔ Network borschevskaya_anna_lab_3_default    Created                                                                                                                             0.0s

+ ✔ Container company                           Started                                                                                                                             0.9s 
+ ✔ Container borschevskaya_anna_lab_3-nginx-1  Started   
+```
+Далее можно осуществлять запросы к сервисам по адресу http://localhost/{location}, где часть пути location меняется в зависимости от сервиса и запроса.
+## Видео-отчет
+Работоспособность лабораторной работы можно оценить в следующем [видео](https://disk.yandex.ru/i/KPNBfnlcgl1auw). 
+Демонстрация взаимодействия с системой производится с применением сервиса Postman.
