+# Лабораторная работа №3 - RESTAPI, Gateway и синхронный обмен между микросервисами
+
+1) Создать 2 микросервиса, реализующих CRUD на связанных сущностях.
+2) Реализовать механизм синхронного обмена сообщениями между микросервисами.
+3) Реализовать шлюз на основе прозрачного прокси-сервера nginx.
+
+# Сущности:
+- VKImages:
+1) ID: Id автогенерируемый в программе.
+2) Url: ссылка на фото пользователя.
+3) Text: текст фото, не содержащийся на фото, а приложенный текст к фото в ВКонтакте.
+- VKUsers:
+1) ID: Id автогенерируемый в программе.
+2) Url: ссылка на пользователя.
+3) PhotoUrl: ссылка на фото пользователя.
+# Как запустить
+Командой  "docker-compose up -d" в папке VKUsers/src/main/java/com/example/vkUsers
+
+# Работа программы
+Так как скриншоты этой программы можно делать очень долго, то основная работа программы будет видна в видео, 
+в данном фотоотчете будут основные аспекты программы.
+
+Начнем с VKImages. Модель следующая:
