+# Лабораторная работа 1
+
+## Описание
+Данная лабораторная работа предназначена для настройки 3 сервисов — **Gitea**, **Redmine** и БД **MySQL** — с использованием Docker Compose. **Gitea** — это лёгкая система контроля версий с веб-интерфейсом, а **Redmine** — система управления проектами и задачами, а также баг-трекер. **MySQL** — база данных, используемая Redmine для хранения данных.
+
+## Запуск проекта
+1. Убедитесь, что у вас установлены **Docker** и **Docker Compose**. 
+2. Клонируйте репозиторий с данным проектом или создайте файл `docker-compose.yml` с конфигурацией, представленной там.
+3. В командной строке перейдите в директорию с файлом `docker-compose.yml`.
+4. Запустите команды:
+   ```bash
+   docker-compose up -d
+   ```
+   Эта команда запустит контейнеры в фоновом режиме.
+5. После запуска:
+   - Gitea будет доступен по адресу: [http://localhost:3000](http://localhost:3000)
+   - Redmine будет доступен по адресу: [http://localhost:8080](http://localhost:8080)
+
+## Конфигурация
+В файле `docker-compose.yml` определены следующие сервисы:
+- **Gitea**:
+  - Запускается из официального образа `gitea/gitea:latest`.
+  - Использует `SQLite` для хранения данных.
+  - Настроен на порту 3000 для веб-доступа и 2222 для SSH.
+- **Redmine**:
+  - Запускается из официального образа `redmine`.
+  - Подключен к базе данных MySQL.
+  - Доступен на порту 8080.
+- **MySQL**:
+  - Запускается из образа `mysql:8.0`.
+  - Используется Redmine для хранения данных.
+  - Настроен с дефолтными пользователем, базой и паролем.
+
+## Остановка проекта
+Для остановки контейнеров запустите:
+```bash
+docker-compose down
+```
+Это завершит работу всех контейнеров и освободит порты.
+
+## Примечания
+- При необходимости вы можете изменить порты или другие параметры, отредактировав файл `docker-compose.yml`.
+- Данные хранятся в именованных томах `gitea_data` и `db_data`, что позволяет сохранять данные при перезапуске контейнеров.

+# Лабораторная работа 2
+
+## Описание
+Данная лабораторная работа предназначена для настройки 2 сервисов (простейшего распределенного приложения) с использованием Docker Compose. **FirstService** — ищет в каталоге /var/data файл с наибольшим количеством строк и перекладывает его в /var/result/data.txt. **SecondService** — ищет наименьшее число из файла /var/result/data.txt (сгенерирован 1-ым сервисом) и сохраняет его третью степень в /var/result/result.txt. 
+
+## Запуск проекта
+1. Убедитесь, что у вас установлены **Docker** и **Docker Compose**.
+2. Клонируйте репозиторий с данным проектом.
+3. В командной строке перейдите в директорию с файлом `docker-compose.yml`.
+4. Запустите команды:
+   ```bash
+   docker-compose up -d
+   ```
+   Эта команда запустит контейнеры в фоновом режиме.
+5. После запуска:
+    - Посмотреть логи первого сервиса о том, что файл создался успешно.
+    - Посмотреть логи второго сервиса о том, что он обработал созданный первым сервисом файл.
+
+## Конфигурация
+В файле `docker-compose.yml` определены следующие сервисы:
+- **FirstService**:
+    - Создает образ из директории `firstService`.
+    - Использует локальную директорию `/var/data` и общую `/var/result` для хранения данных.
+- **SecondService**:
+    - Создает образ из директории `secondService`.
+    - Использует общую `/var/result` директорию для хранения данных.
+    - Запускается после первого сервиса.
+
+## Остановка проекта
+Для остановки контейнеров запустите:
+```bash
+docker-compose down
+```
+Это завершит работу всех контейнеров.
+
+## Примечания
+- При необходимости можно изменить директорию с данными или другие параметры, отредактировав файл `docker-compose.yml`.

+# Лабораторная работа 3
+
+## Описание
+Данная лабораторная работа предназначена для настройки 3 сервисов — **Melon**, **Water** и прокси-сервер **Nginx** — с использованием Docker Compose. **Melon** — сервис с дынями, где для каждого свой арбуз, а **Water** — сервис с водой и связанных с ними арбузами. **Nginx** — прокси-сервер, работающий на Unix-подобных операционных системах.
+
+## Запуск проекта
+1. Убедитесь, что у вас установлены **Docker** и **Docker Compose**.
+2. Клонируйте репозиторий с данным проектом.
+3. В командной строке перейдите в директорию с файлом `docker-compose.yml`.

+    - Water будет доступен по адресу: [http://localhost:8081](http://localhost:8081)
+
+## Конфигурация
+В файле `docker-compose.yml` определены следующие сервисы:
+- **Melon**:
+    - Настроен на порту 8080 для веб-доступа.
+    - Обращается к **Nginx** для доступа к сервису **Water**.
+    - Реализует базовые CRUD-операции.
+- **Water**:
+    - Настроен на порту 8081 для веб-доступа.
+    - Реализует базовые CRUD-операции.
+- **Nginx**:
+    - Запускается из образа `nginx`.
+    - Используется для проксирования запросов.
+
+## Остановка проекта
+Для остановки контейнеров запустите:
+```bash
+docker-compose down
+```
+Это завершит работу всех контейнеров и освободит порты.
+
+## Примечания
+- При необходимости вы можете изменить порты или другие параметры, отредактировав файл `docker-compose.yml`.

+## Отчет по Docker Compose конфигурации
+
+### Краткое описание:
+
+Данная конфигурация Docker Compose запускает набор сервисов, необходимых для работы WordPress и MediaWiki. Она включает в себя:
+
+- **WordPress:** веб-сервис для блогов и CMS
+- **MySQL:** база данных для хранения данных WordPress
+- **RabbitMQ:** брокер сообщений для потенциального использования в будущем
+- **MediaWiki:** вики-движок для создания и редактирования вики-страниц
+
+### Запуск лабораторной работы:
+
+1. Установить Docker и Docker Compose.
+2. Сохранить конфигурацию в файл docker-compose.yml.
+3. Запустить команду docker-compose up --build
+
+### Используемые технологии:
+
+- **Docker Compose:** инструмент для определения и запуска многоконтейнерных приложений.
+- **Docker:** платформа для создания, развертывания и запуска контейнеров.
+- **WordPress:** популярная платформа для создания блогов и CMS.
+- **MySQL:** популярная система управления базами данных.
+- **RabbitMQ:** брокер сообщений, используемый для асинхронного обмена сообщениями.
+- **MediaWiki:** свободное программное обеспечение для создания и редактирования вики-страниц.
+
+### Функциональность:
+
+Конфигурация запускает следующие сервисы:
+
+- **WordPress:** работает на порту 8080, доступен по адресу http://localhost:8080.
+- **MySQL:** предоставляет базу данных для WordPress и MediaWiki.
+- **RabbitMQ:** работает на порту 5672, доступен по адресу http://localhost:15672 для управления.
+- **MediaWiki:** работает на порту 8081, доступен по адресу http://localhost:8081.
+
+### Дополнительные сведения
+
+- **Volumes**: используются для хранения данных сервисов, чтобы они не терялись при перезапуске контейнеров.
+- **Depends_on**: указывает на зависимость между сервисами, например, WordPress зависит от MySQL.
+- **Restart policy**: определяет, как сервисы будут перезапускаться после сбоя.
+
+### Видео
+
+https://vk.com/video/@artamonovat?z=video212084908_456239356%2Fpl_212084908_-2
+
+### Заключение:
+
+Данная конфигурация Docker Compose обеспечивает простой и удобный способ запуска и управления несколькими сервисами, связанными с WordPress и MediaWiki. Она позволяет разработчикам легко развертывать и управлять приложениями в изолированной среде.

+## Лабораторная работа №2
+### Выполнила Артамонова Татьяна ПИбд-42
+
+**Вариант 1: Программа 4 - Количество символов в именах файлов из каталога /var/data**
+
+- Формирует файл /var/result/data1.txt так, что каждая строка файла - количество символов в именах файлов из каталога /var/data.
+
+**Вариант 2: Программа 3 - Количество чисел в последовательности**
+
+- Ищет набольшее число из файла /var/result/data1.txt и сохраняет количество таких чисел из последовательности в /var/result/data2.txt.
+
+**Структура проекта:**
+
+1. В папках worker-1, worker-2 лежат выполняемые файлы .py и Dockerfile-ы с необходимым набором инструкций.
+2. В папке data лежат файлы, длину имен которых нужно посчитать.
+3. В папке result лежат файлы с результатами выполнения программ. data1.txt - результат выполнения main1.py (worker-1), data2.txt - результат выполнения main2.py (worker-2). Данные в data2 рассчитываются из данных data1.
+4. Файл .gitignore - для указания, какие файлы отслеживать, а какие - нет.
+5. docker-compose.yml - для определения и управления контейнерами Docker.
+
+**Команда для запуска** - docker-compose up --build

+## Лабораторная работа №3 ПИбд-42 Артамоновой Татьяны
+
+### Цель: 
+* Реализовать два микросервиса, которые взаимодействуют друг с другом через синхронный обмен сообщениями (HTTP-запросы). Для доступа к микросервисам используется шлюз Nginx, реализованный с помощью Docker Compose.
+
+### Технологии:
+
+* Python: Язык программирования для реализации микросервисов. 
+* Flask: Фреймворк Python для создания веб-приложений, использован для создания REST API микросервисов.
+* requests: Библиотека Python для отправки HTTP-запросов, использован для синхронного обмена сообщениями между микросервисами.
+* flask_cors: Расширение Flask, которое позволяет микросервисам получать доступ к данным из других доменов.
+* Docker: Технология контейнеризации для упаковки и запуска микросервисов. 
+* Docker Compose: Инструмент для определения и управления многоконтейнерными приложениями, использован для запуска микросервисов и шлюза Nginx. 
+* Nginx: Сетевой прокси-сервер, использован как шлюз для доступа к микросервисам.
+
+### Функциональность:
+
+#### Микросервис vacancies-service:
+*  Реализует CRUD операции для вакансий (GET, POST, PUT, DELETE).
+*  Сохраняет данные о вакансиях в памяти (в словаре vacancies).
+*  Получает информацию о резюме из микросервиса resumes-service через HTTP-запрос.
+*  Включает информацию о резюме в ответ JSON для вакансии. 
+#### Микросервис resumes-service:
+*  Реализует CRUD операции для резюме (GET, POST, PUT, DELETE).
+*  Сохраняет данные о резюме в памяти (в словаре resumes). 
+#### Шлюз Nginx:
+*  Перенаправляет HTTP-запросы на соответствующие микросервисы.
+*  Предоставляет единую точку входа для доступа к микросервисам.
+
+### Запуск программы:
+
+*  Запуск команды docker-compose up -d
+

+
+### Запуск приложений и анализ скорости обработки
+
+1. Запуск Publisher, Consumer 1 и Consumer 2.
+* Consumer 1: Очередь order_queue_1 будет иметь некоторое количество сообщений, так как Consumer 1 обрабатывает сообщения с задержкой в 2 секунды.
+* Consumer 2: Очередь order_queue_2 будет практически пустой, так как Consumer 2 обрабатывает сообщения моментально.
+
+2. Запуск нескольких копий Consumer 1
+* Очередь order_queue_1 будет иметь меньше сообщений, так как 3 Consumer-а обрабатывают сообщения быстрее, чем 1 Consumer.
