+# Лабораторная работа номер 1
+
+> Здравствуйте меня зовут Балахонов Данила группа ПИбд-42
+> 
+> *— Балахонов Данила ПИбд-42*
+
+Видео лабораторной работы номер 1 доступно по этой [ссылке](https://drive.google.com/file/d/1Up_JzDcK_TjYLixpfYXN7PhJmOeg_Uck/view?usp=sharing).
+
+## Как запустить лабораторную работу номер 1?
+### Необходимые компоненты для запуска лабораторной работы номер 1
+> Здесь рассказана установка необходимых компонентов для запуска лабораторной работы номер 1 под дистрибутив GNU/Linux **Ubuntu**.
+
+Для запуска лабораторной работы номер 1 необходимы такие компоненты: 
+ - Git
+ - Docker
+ - Docker compose
+
+Чтобы установить **Git**, необходимо ввести данные команды в командную строку:
+``` bash
+sudo apt-get update
+sudo apt-get install git
+```
+
+Чтобы установить **Docker** и **Docker compose**, стоит ввести такие команды:
+``` bash
+# Настройка репозитория Docker
+sudo apt-get update
+sudo apt-get install ca-certificates curl
+sudo install -m 0755 -d /etc/apt/keyrings
+sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
+sudo chmod a+r /etc/apt/keyrings/docker.asc
+
+echo \
+  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
+  $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
+  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
+sudo apt-get update
+
+# Установка Docker и его компонентов
+sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
+```
+### Запуск лабораторной работы номер 1
+Для запуска лабораторной работы номер 1 необходимо **склонировать** репозиторий в любую папку и **перейти на ветку** balakhonov_danila_lab_1.
+Далее в папке с `docker-compose.yaml` нужно вызвать такую команду:
+``` bash
+sudo docker-compose up -d
+```
+Таким образом будут запущены контейнеры в фоновом режиме.
+## Какие технологии были использованы?
+Для выполнения лабораторной работы номер 1 использовались такие технологии, как: *git*, *docker*, *docker compose*.
+
+Сервисы, выбранные для запуска в docker-compose файле:
+ - *Gitea* - удобный сервис отслеживания версий разрабатываемого ПО
+ - *MediaWiki* - сервис создания и ведения электронной энциклопедии
+ - *PostgreSQL* - база данных, используемая сервисами выше
+
+Системой, на которую были установлены указанные технологии, является Ubuntu 22.
+## Что делает лабораторная работа номер 1?
+Лабораторная работа номер 1 заключается в написании docker-compose файла для удобного запуска и администрирования сразу нескольких сервисов в docker-контейнерах.

+# Лабораторная работа 2
+В рамках лабораторной работы были реализованы два сервиса, для которых выходные данные первого являются входными данными второго.
+## Описание
+Варианты:
+Первый сервис - 5
+Второй сервис - 1
+Оба сервиса являются консольным приложением с сгенерированным dockerfile
+В результате были проброшены папки следующим образом:
+для первого сервиса :
+```
+    volumes:
+      - ./FilesInput/First:/var/data
+      - ./FilesInput/Second:/var/result
+```
+для второго сервиса:
+```
+    volumes:
+      - ./FilesInput/Second:/var/data
+      - ./FilesOutput:/var/result
+```
+## Запуск
+Для запуска лабораторной работы необходимо иметь запущенный Docker.
+Из папки, где находится файл docker-compose.yml запустить консоль и выполнить:
+```
+docker compose up --build
+```
+Флаг `--build` указывает на то, что необходимо выполнить сборку исходников. 
+После сборки мы получим следующие логи:
+[+] Running 3/2
+ ✔ Network dozorova_alena_lab_2_default     Created                                                                0.2s
+ ✔ Container dozorova_alena_lab_2-first-1   Created                                                                0.1s

+FROM mcr.microsoft.com/dotnet/runtime:6.0 AS base #базовый образ сборки

+COPY . . #копируем в папку сборки
+WORKDIR "/src/."

+
+FROM build AS publish #все, что создалось в папке publish
+ARG BUILD_CONFIGURATION=Release

+WORKDIR /app #указываем рабочую папку
+COPY --from=publish /app/publish . #опубликованное копируем в app
+ENTRYPOINT ["dotnet", "ConsoleApp2.dll"] #указываем команду запуска приложения
+```
+
+## Особенности compose файла
+Директива`depends_on` позволяет указать, какого сервиса мы дожидаемся, прежде чем запустимся. 
+Директива `build` позволяет использовать не уже готовый образ, а тот, что будет собран непосредственно в момент запуска.
+## Видеодемонстрация
+Был записан видеоролик, демонстрирующий процесс запуска и работы сервисов. Он расположен по [адресу](https://drive.google.com/file/d/1BOt_Ja9AanINPjJyRKzgUaghRGwJYdd7/view?usp=drive_link)

+# Лабораторная работа 4
+В рамках данной работы были реализованы несколько проектов, работающих с RabbitMQ.
+## tutorial
+Для каждого урока были созданы консольные проекты 
+### "Hello World!"
+![Task 1](image-4.png)
+### Work Queues
+![Task 2](image-5.png)
+### Publish/Subscribe
+![Task 3](image-6.png)
+## Описание
+В качестве предметной области была выбрана система запросов отчета двух видов: отчета и ошибок.  
+## Запуск
+Для запуска лабораторной работы необходимо иметь запущенный Docker на устройстве.
+Необходимо перейти в папку, где располагается данный файл. Далее открыть терминал и ввести команду:
+```
+docker compose up -d --build
+```
+Порты для RabbitMQ были 8081 (для UI) и 5672.
+## Анализ
+Первоначальный вариант запуска предполагает, что имеется всего 2 потребителя:
+ 1. Тратит на обработку сообщения 2-3 секунды
+ 2. Тратит на обработку сообщения крайне малое время
+Задержка при обработке понижает пропускную способность обработчика, что вызывает переполнение очереди. Это подтверждается скринами.
+<br/>
+![alt text](image.png)
+<br/>
+![alt text](image-1.png)
+<br/>
+Теперь запустим несколько обычных обработчиков. Очередь не переполнена постоянно, а периодически, соответственно обработчики вполне справляются с потоком сообщений и увеличение их количества позволит в принципе избавиться от переполнения 
+<br/>

+
+## Видеодемонстрация
+Демонстрация: (https://drive.google.com/file/d/16gJMGbMKSFZ_I5gCzuDekpAqUrhbpFRA/view?usp=sharing) Стоит обратить внимание на то, что настройки docker compose файла не гарантируют верный порядок подъема контейнеров, из-за чего некоторые контейнеры пришлось перезапустить.
