# Отчёт по лабораторной работе №2
|
||||
|
||||
Выполнил: студент гр. ИСЭбд-41 Мутрисков Данила
|
||||
|
||||
Вариант программы 1: Ищет в каталоге `/var/data` самый большой по объёму файл и перекладывает его в `/var/result/data.txt`.
|
||||
|
||||
Вариант программы 2: Ищет наименьшее число из файла `/var/data/data.txt` и сохраняет его третью степень в `/var/result/result.txt`.
|
||||
|
||||
## Создание приложений
|
||||
|
||||
Создадим 2 приложения.
|
||||
Создано два приложения .Net 7.0 на языке C# с помощью команд:
|
||||
|
||||
Для создания обычных консольных приложений воспользуемся командами:
|
||||
|
||||
```sh
|
||||
dotnet new console -o worker-1
|
||||
dotnet new console -o worker-2
|
||||
```
|
||||
|
||||
Согласно варианту программа 1 должна выбирать самый большой по объему файл из папки `/var/data` и перемещать его в папку `/var/result/data.txt`.
|
||||
|
||||
[Исходный текст программы worker-1](worker-1/Program.cs)
|
||||
|
||||
Согласно варианту программа 2 должна найти в файле `/var/data/data.txt` наименьшее число и сохранить его третью степень в файл `/var/result/result.txt`.
|
||||
|
||||
[Исходный текст программы worker-2](worker-2/Program.cs)
|
||||
|
||||
Дополнительно создан файл [.gitignore](.gitignore) для того, чтобы не закоммитить в git ничего лишнего.
|
||||
|
||||
## Настройка окружения
|
||||
|
||||
Для связи двух приложений воспользуемся следующей схемой:
|
||||
|
||||
1. Каталог `./data` должен быть примонтирован в каталог `/var/data` для программы 1.
|
||||
Оттуда будут браться исходные данные.
|
||||
2. Каталог `./result` должен быть примонтирован в каталог `/var/result` для программы 1.
|
||||
Туда будут складываться промежуточные данные.
|
||||
3. Каталог `./data` также должен быть примонтирован в каталог `/var/data` для программы 2.
|
||||
Оттуда будут браться промежуточные результаты.
|
||||
4. Каталог `./result` должен быть примонтирован в каталог `/var/result` для программы 2.
|
||||
Туда будут складывать результаты финальной обработки.
|
||||
|
||||
Для каждой программы были созданы файлы Dockerfile ([программа 1](worker-1/Dockerfile), [программа 2](worker-2/Dockerfile)) с подробным описанием процесса сборки.
|
||||
|
||||
Был создан файл [docker-compose.yml](docker-compose.yml), в котором указан манифест для запуска распределённого приложения.
|
||||
|
||||
Дополнительно был создан файл [.dockerignore](.dockerignore) и дополнен [.gitignore](.gitignore), чтобы исключить для сборки и коммита всё лишнее.
|
||||
|
||||
## Сборка и запуск
|
||||
|
||||
В каталог `./data` помещены 2 файла.
|
||||
Произведение чисел в первом файле равна 1078
|
||||
|
||||
Для запуска приложения необходимо ввести команду `docker compose up ---build`.
|
||||
|
||||
Результат запуска после сборки:
|
||||
|
||||
```
|
||||
✔ Container lab_2-worker-1-1 Created 0.0s
|
||||
✔ Container lab_2-worker-2-1 Created 0.0s
|
||||
Attaching to lab_2-worker-1-1, lab_2-worker-2-1
|
||||
lab_2-worker-1-1 exited with code 0
|
||||
lab_2-worker-2-1 | 2197
|
||||
lab_2-worker-2-1 exited with code 0
|
||||
```
|
||||
|
||||
В результате в каталоге `./result` создался файл `result.txt` с содержимым `2197`, что соответствует входным данным.
|
||||
|
||||
Изменение значений в файлах из каталога `./data` также изменяет содержимое в файлах из каталога `./result`.
