+## Задание
+Развернуть не менее 3х сервисов через docker-compose.
+
+## Выполнение
+Было выбрано три сервиса: RabbitMQ, MediaWiki, WordPress.
+
+Yaml-файл был настроен следующим образом:
+* блок services, где перечислены разворачиваемые сервисы.
+* непосредственно перечисление сервисов: rabbitmq, mediawiki, wordpress.
+* у каждого сервиса описаны: image - образ, на основе которого создаётся контейнер, port - проброс порта с хоста на гостевую машину (контейнер), volumes - указание на том с путём хранения внутри него.
+* блок volumes, где описаны тома - отделённые постоянные хранилища информации для контейнеров.
+
+Результаты:

+## Задание
+Развернуть два взаимосвязанных сервиса по варианту:
+
+Вариант 1:
+* Сервис 1 ищет в каталоге /var/data файл с наибольшим количеством строк и перекладывает его в /var/result/data.txt.
+* Сервис 2 ищет набольшее число из файла /var/data/data.txt и сохраняет его вторую степень в /var/result/result.txt.
+
+## Выполнение
+Были написаны два сервиса на языке python с технологией flask. Они выводят на страницу кнопки, по которым происходило срабатывание скриптов по варианту.
+
+Для сервисов прописаны файлы Dockerfile, описывающие создание контейнеров:
+* Для обоих контейнеров выбирается Python 9.
+* Оба контейнера проявляют порты, на которых работает приложение: 8081 для первого и 8082 для второго.
+* В контейнерах создаются папки /work для файлов скриптов, папки /var/result для обоих сервисов и /var/data для первого скрипта.
+* В оба контейнера устанавливается пакет Flask.
+* Выбирается рабочая директория /work и туда копируются файлы скриптов.
+* Командой запускаются сами скрипты.
+
+Общий yaml-файл развёртки был настроен следующим образом:
+* блок services, где перечислены разворачиваемые сервисы.
+* для каждого сервиса прописан build, где объявляется его папка и докерфайл создания.
+* для каждого сервиса прописано отображение портов на такие же хоста.
+* для каждого сервиса прописано монтирование нужных папок хостовой системы как соответствующих папок внутри контейнеров.
+
+## Результат
+Пример выполнения:
+
+Исходные данные: три файла в папке /var/data, средний файл имеет наибольшее количество строк и наибольшее число 40.
+
+Ход работы: нажатие кнопок на странице первого сервиса, потом - второго.
+Запросы:
+![Запросы](screens/requests.png)
+Выходные данные: средний файл, перенесённый в /var/result/data.txt, файл result.txt там же с результатом вычислений - числом 1600. Результат выведен на страницу второго сервиса:

+## Задание
+
+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.
+
+Вариант: сообщения и пользователи
+
+## Выполнение
+Были написаны два сервиса на языке python с технологией flask: 
+* Сервис msg_service, хранящий данные о сообщениях и реализующий CRUD операции с ними через HTTP запросы.
+* Сервис usr_service, хранящий данные о пользователях и реализующий CRUD операции с ними через HTTP запросы. 
+
+Сервисы синхронно сообщены - сервис пользователей запрашивает данные у сервиса сообщений для получения сообщений пользователя.
+
+Для сервисов прописаны файлы Dockerfile, описывающие создание контейнеров:
+* Для обоих контейнеров выбирается Python 3.9.
+* Оба контейнера проявляют порты, на которых работает приложение: 8081 для сообщений и 8082 для пользователей.
+* В оба контейнера устанавливаются пакеты Flask и requests.
+* Выбирается рабочая директория /work и туда копируются файлы скриптов.
+* Командой запускаются сами скрипты.
+
+Общий yaml-файл развёртки был настроен следующим образом:
+* блок services, где перечислены разворачиваемые сервисы.
+* для каждого сервиса прописан build, где объявляется его папка и докерфайл создания и зависимости.
+* для сервиса nginx прописан порт для отображения вовне.
