+# Отчёт по лабораторной работе №2
+
+Выполнил: студент гр. ИСЭбд-41, Мельников Кирилл.
+
+Вариант программы 1: 6. Берёт из каталога `/var/data `случайный файл и перекладывает его в `/var/result/data.txt`.
+
+Вариант программы 2: 4. Ищет наименьшее число из файла `/var/data/data.txt` и сохраняет количество таких чисел из последовательности в `/var/result/result.txt`.
+
+## Создание приложений
+
+Создадим 2 приложения.
+Был выбран язык C# и технология .NET 5.
+
+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 брать из каталога `/var/data `случайный файл и перекладывать его в `/var/result/data.txt`.
+
+[Исходный код программы worker-1](worker-1/Program.cs)
+
+Согласно варианту программа 2 должна искать наименьшее число из файла `/var/data/data.txt` и сохранять количество таких чисел из последовательности в `/var/result/result.txt`.
+
+[Исходный код 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-1` должен быть примонтирован в каталог `/var/result` для программы 2.
+   Туда будут складываться промежуточные данные.
+3. Каталог `./result-1` 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.
+
+
+## Сборка и запуск
+
+1. В каталог `./data` помещены 3 файла с различными названиями и содержимым.
+
+![](scrins/1.png)
+
+На выходе программа должна записать данные из рандомного файла директории `/var/data`.
+
+![](scrins/5.png)
+![](scrins/3.png)
+![](scrins/4.png)
+
+2. Теперь, обрабатывая эти файлы:
+
+![](scrins/2.png)
+
+На выходе программа должна записать число 5 в `./result` так как в файле c названием data.txt минимальное число = 11, которое встречается 5 раз.
+
+![](scrins/6.png)
+
+Для запуска приложения необходимо ввести команду `docker compose up --build`.
+Результат запуска после сборки:
+
+```
+[+] Running 2/1
+ ✔ 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  | Файл /var/data/data.txt успешно скопирован в /var/result/data.txt.
+lab_2-worker-1-1 exited with code 0
+lab_2-worker-2-1  | Количество наименьших чисел сохранено в файле: /var/result/result.txt
+lab_2-worker-2-1 exited with code 0
+```
+
+В результате в каталоге `./result` создался файл `result.txt` с содержимым `5`, что соответствует входным данным.
+
+Изменение значений в файлах из каталога `./data` также изменяет содержимое в файлах из каталогов `./result-1` и `./result`.

-## Разработка демонстрационных приложений
-
-Предметная область: Дополенительные соглашения и договора на заселение в отель Туристического агентства.
-Разработа три приложения согласно предметной области.
-
-1. Publisher
-
-```py
-import pika
-import time
-import random
-
-collection = ["Application for Travel Agency", "Buying tickets", "Execution of the agreement", "Check-into a hotel"]
-
-connection = pika.BlockingConnection(pika.ConnectionParameters('localhost'))
-channel = connection.channel()
-
-channel.exchange_declare(exchange='Agreements', exchange_type='fanout')
-
-while True:
-    message = f"Message: {random.choice(collection)}"
-
-    channel.basic_publish(exchange='Agreements', routing_key='', body=message)
-
-    time.sleep(1)
-
-connection.close()
-```
-
-2. Consumer 1.
-
-```py
-import pika
-import time
-
-def process_message(ch, method, properties, body):
-    print(f"Получено сообщение: {body}")
-    time.sleep(3)
-    print("Сообщение успешно обработано")
-
-connection = pika.BlockingConnection(pika.ConnectionParameters('localhost'))
-channel = connection.channel()
-
-result = channel.queue_declare(queue='', exclusive=True)
-queue_name = result.method.queue
-
-channel.queue_bind(exchange='Agreements', queue=queue_name)
-
-channel.basic_consume(queue=queue_name, on_message_callback=process_message, auto_ack=True)
-
-print('Ожидание сообщений...')
-channel.start_consuming()
-```
-
-3. Consumer 2.
-
-```py
-import pika
-
-
-def process_message(ch, method, properties, body):
-    print(f"Получено сообщение: {body}")
-    print("Сообщение успешно обработано")
-
-connection = pika.BlockingConnection(pika.ConnectionParameters('localhost'))
-channel = connection.channel()
-
-result = channel.queue_declare(queue='', exclusive=True)
-queue_name = result.method.queue
-
-channel.queue_bind(exchange='Agreements', queue=queue_name)
-
-channel.basic_consume(queue=queue_name, on_message_callback=process_message, auto_ack=True)
-
-print('Ожидание сообщений...')
-channel.start_consuming()
-```
-
-## Результаты выполнения лабораторной работы
-
-Результат отработки Consumer_1:
-
-![](scrins/maintask1.png)
-
-Результат отработки Consumer_2:
-
-![](scrins/maintask2.png)
-
-![](scrins/maintask_dop.png)
-
-Вывод: Consumer_2 нагружает меньше памяти, чем Consumer_1 и принимает сообщения гораздо быстрее, тем самым не позволяя очереди накапливать огромное количество сообщений.
