## 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.
