# Лабораторная работа №2
|
||||||
|
|
||||||
|
Цель: изучение техники создания простого распределенного приложения.
|
||||||
|
|
||||||
|
Задачи:
|
||||||
|
|
||||||
|
- Согласно вышему варианту (выбирайте любой) разработать два приложения такие, что результат первого является исходными данными для второго.
|
||||||
|
- Изучить файлы сборки образов docker и разработать их для созданных приложений.
|
||||||
|
- Собрать файл docker-compose.yml для запуска приложений. Разобраться с монтированием каталогов из хост-системы.
|
||||||
|
- Правильно закоммитить результат без лишних файлов.
|
||||||
|
- Оформить pull request по правилам и отправить его на проверку.
|
||||||
|
|
||||||
|
# Разработка двух приложений
|
||||||
|
|
||||||
|
Вариант первого приложения(worker-1): 5 - Ищет в каталоге /var/data файл с самым коротким названием и перекладывает его в /var/result/data.txt
|
||||||
|
Вариант второго приложения(worker-2): 1 - Ищет набольшее число из файла /var/data/data.txt и сохраняет его вторую степень в /var/result/result.txt
|
||||||
|
|
||||||
|
## Структура проекта
|
||||||
|
|
||||||
|
![](/screens/Screenshot_1.png)
|
||||||
|
|
||||||
|
# Работа программы
|
||||||
|
|
||||||
|
- Создание двух директорий: worker-1 и worker-2 для реализаций двух программ.
|
||||||
|
- Описание Dockerfile для создания образов для обоих программ.
|
||||||
|
|
||||||
|
## Docker файл для первого сервиса

## После запуска контейнера создаются файлы `data.txt` и `result.txt`:
