+# Лабораторная работа номер 3
+
+> Здравствуйте меня зовут Балахонов Данила группа ПИбд-42
+> 
+> *— Балахонов Данила ПИбд-42*
+
+Видео лабораторной работы номер 3 доступно по этой [ссылке](https://drive.google.com/file/d/1KplDSt-BUQl9OUTM9x7VZcGeokuLhdOD/view?usp=sharing).
+
+## Как запустить лабораторную работу номер 3?
+### Необходимые компоненты для запуска лабораторной работы номер 3
+> Здесь рассказана установка необходимых компонентов для запуска лабораторной работы номер 3 под дистрибутив GNU/Linux **Ubuntu**.
+
+Для запуска лабораторной работы номер 3 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 3
+Для запуска лабораторной работы номер 3 необходимо **склонировать** репозиторий в любую папку и **перейти на ветку** balakhonov_danila_lab_3.
+Далее в папке с `docker-compose.yaml` нужно вызвать такую команду:
+``` bash
+sudo docker-compose up --build
+```
+Таким образом контейнеры будут подготовлены и запущены.
+Доступ к функционалну системы происходит через nginx, через порт 80.
+## Какие технологии были использованы?
+Для выполнения лабораторной работы номер 3 были использованы такие технологии, как:
+ - Dockerfile
+ - Docker compose
+ - Git
+ - .NET SDK и С# в частности
+ - ASP.NET Core
+ - Node.js
+ - Express
+## Что делает лабораторная работа номер 3?
+Суть лабораторной работы номер 3 заключается в распределении функционала между несколькими сервисами, а также реализации взаимодействия между ними.
