+# Отчет. Лабораторная работа 2
+
+В рамках лабораторной работы №2 были написаны два сервиса, работающих с текстовыми файлами.
+Для первого сервиса был выбран вариант задания №5:
+```
+Ищет в каталоге /var/data файл с самым коротким названием и перекладывает его в /var/result/data.txt.
+```
+А для второго - №2:
+```
+Ищет наименьшее число из файла /var/data/data.txt и сохраняет его третью степень в /var/result/result.txt.
+```
+## Описание 
+Сначала сервис first перемещает данные из файла с самым коротким названием, находящегося в указанной примонтированной директории, в выходную папку. 
+Доступ к выходной папке имеет второй сервис, который выводит наименьшее число из помещенного первым сервисом файла 
+в третьей степени в выходной файл.
+Выходной файл расположен в примонтированной директории и доступен на машине, где запускаются сервисы.
+
+В Dockerfile используется многоэтапная сборка с использованием нескольких базовых образов на каждом этапе. 
+Описание значения каждой строки есть в Dockerfile в сервисе first.
+
+В файле docker-compose.yml приведено описание новых строк, связанных с подключением примонтированных томов.
+Стоит отметить, что для "общения" сервисов используется общий том common, который монтируется в контейнер по пути /var/result. Это позволяет сохранять результаты 
+работы первого сервиса для использования вторым сервисом.
+## Как запустить
+Для того, чтобы запустить сервисы, необходимо выполнить следующие действия:
+1. Установить и запустить Docker Engine или Docker Desktop
+2. Через консоль перейти в папку, в которой расположен файл docker-compose.yml
+3. Выполнить команду:
+```
+docker compose up --build
+```
+В случае успешного запуска всех контейнеров в консоли будет выведено следующее сообщение:
+```
+ ✔ Network borschevskaya_anna_lab_2_default     Created                                                                                                                                                       0.1s

+ ✔ Container borschevskaya_anna_lab_2-second-1  Created                                                                                                                                                       0.1s
+Attaching to borschevskaya_anna_lab_2-first-1, borschevskaya_anna_lab_2-second-1
+```
+Далее, в консоль каждого сервиса будут выведены сообщения о том, как прошла обработка файлов.
+В случае отсутствия заданных значений переменных окружения INPUT_PATH и OUTPUT_PATH и 
+в иных исключительных ситуация будет выведена информация об этом.
+## Видео-отчет
+Работоспособность лабораторной работы можно оценить в следующем [видео](https://disk.yandex.ru/i/LFxdyRUFQDwXEQ).

+# Кашин Максим ПИбд-42
+
+## Описание
+
+Этот проект разворачивает среду с базой данных MySQL, системами управления проектами Redmine и платформой для создания сайтов WordPress с использованием Docker Compose. Ниже приведены шаги для запуска и настройки.
+
+## 0. Предварительные действия
+
+Перед запуском Docker Compose выполнил следующие шаги:
+
+1. Установил [Docker Desktop](https://www.docker.com/products/docker-desktop) для моей операционной системы.
+2. Настроил брандмауэр Windows и разрешил доступ Docker.
+3. Открыл PowerShell с правами администратора и выполнил следующие команды:
+    ```bash
+    net start vmcompute
+    wsl --set-default-version 2
+    ```
+
+## 1. Структура и запуск сервиса
+
+Файл `docker-compose.yml` содержит описание трех сервисов:
+- **db (MySQL)** – база данных;
+- **redmine (Redmine)** – система управления проектами;
+- **wordpress (WordPress)** – платформа для создания сайтов.
+
+Запуск всех сервисов происходит через команду:
+    ```bash
+    docker-compose up -d
+    ```
+
+## 2. Сервис MySQL
+
+Сервис `db` представляет собой контейнер с MySQL версии 8.0.
+
+- **Образ**: `mysql:8.0`
+- **Переменные окружения**:
+  - `MYSQL_ROOT_PASSWORD` — пароль для пользователя root.
+  - `MYSQL_DATABASE` — имя создаваемой базы данных (exampledb).
+  - `MYSQL_USER` — имя пользователя базы данных (exampleuser).
+  - `MYSQL_PASSWORD` — пароль пользователя базы данных (examplepass).
+- **Тома (volumes)**:
+  - `db-data:/var/lib/mysql` — том для хранения данных базы данных.
+
+Сервис MySQL необходим для работы как Redmine, так и WordPress.
+
+## 3. Сервис Redmine
+
+Сервис `redmine` представляет собой контейнер с системой управления проектами Redmine.
+
+- **Образ**: `redmine`
+- **Порты**:
+  - `8080:3000` — Redmine будет доступен по адресу http://localhost:8080.
+- **Переменные окружения**:
+  - `REDMINE_DB_DATABASE` — имя базы данных (exampledb).
+  - `REDMINE_DB_MYSQL` — имя хоста базы данных (db).
+  - `REDMINE_DB_PASSWORD` — пароль для подключения к базе данных (example).
+  - `REDMINE_SECRET_KEY_BASE` — секретный ключ для работы с сессиями.
+- **Тома (volumes)**:
+  - `redmine:/usr/src/redmine/files` — том для хранения файлов Redmine.
+
+## 4. Сервис WordPress
+
+Сервис `wordpress` представляет собой контейнер с платформой WordPress.
+
+- **Образ**: `wordpress`
+- **Порты**:
+  - `8081:80` — WordPress будет доступен по адресу http://localhost:8081.
+- **Переменные окружения**:
+  - `WORDPRESS_DB_HOST` — хост базы данных (db).
+  - `WORDPRESS_DB_USER` — имя пользователя базы данных (exampleuser).
+  - `WORDPRESS_DB_PASSWORD` — пароль для подключения к базе данных (examplepass).
+  - `WORDPRESS_DB_NAME` — имя базы данных (exampledb).
+- **Тома (volumes)**:
+  - `wordpress:/var/www/html` — том для хранения файлов WordPress.
+
+## 5. Томa данных
+
+Для хранения данных и постоянства контейнеров используются три тома:
+
+- `wordpress` — для данных WordPress.
+- `db-data` — для данных MySQL.
+- `redmine` — для файлов Redmine.
+
+## 6. Остановка сервисов
+
+Для остановки и удаления всех контейнеров необходимо выполнить команду:
+    ```bash
+    docker-compose down
+    ```

+# Лабораторная работа 3
+Данная работа посвящена теме синхронного обмена сообщениями между сервисами, а так же шлюзам, для взаимодействия с внешним миром.
+## Описание
+В качестве предметной области использовался пример 18-го варианта. Имеются 2 сущность: контрагент(только имя) и договор(номер, ФИО менеджера, дата создания и статус).
+Для реализации была выбрана платформа ASP.net. Информация хранится в СУБД Postgres, которая так же поднимается в контейнере(вместе с остальными сервисами)
+Система позволяет проводить с сущностями базовые CRUD операции. В случае договора, имеется возможность получения его в связке с информацией по контрагенту(не просто Id, но и имя). В этот момент сервисы и взаимодействуют друг с другом. Для этого используется шлюз(напрямую сервисы друг о друге могут и не знать, общение как с внешним миром так и между собой только через nginx шлюз)
+В качестве интерфейса имеется Swagger, который можно использовать для отправки запросов. Он и будет показан в видеодеомнстрации
+## Запуск
+Для запуска лабораторной работы необходимо иметь запущенный движок Docker на устройстве.
+Необходимо перейти в папку, где располагается данный файл. Далее открыть терминал и ввести команду:
+```
+docker compose up -d --build
+```
+Важно, чтобы в этот момент на компьютере был свободен порт 80.
+В результате, после сборки вся система запустится и Swagger-ы будут доступны по путям http://localhost/first/swagger и http://localhost/second/swagger
+## Видеодемонстрация
+Был записан видеоролик, демонстрирующий процесс запуска и работы системы, а так же всех её основных функйи. Он расположен по [адресу](https://drive.google.com/file/d/17OwZ6kEJ-AaW0uMTIfNtolyp-oyy9OfT/view?usp=sharing)

+## Лабораторная работа №1: Знакомство с docker и docker-compose
+
+---
+
+**Цель:**  изучение современных технологий контейнеризации.
+
+**Задачи:**
+
+1. Установить средство контейнеризации docker.
+2. Изучить применение и принципы docker.
+3. Изучить утилиту docker-compose и структуру файла docker-compose.yml.
+4. Развернуть не менее 3х различных сервисов при помощи docker-compose.
+5. Оформить отчёт в формате Markdown и создать Pull Request в git-репозитории.
+
+---
+
+**Сервисы:**
+
+* **Gitea:** Легковесная и самодостаточная система управления версиями кода с веб-интерфейсом. 
+* **Postgres:** Мощная система управления реляционными базами данных с открытым исходным кодом.
+* **Redis:** Высокопроизводительное хранилище данных типа "ключ-значение", используемое для кэширования, сессий и других задач.
+
+---
+
+**Инструкция по запуску:**
+
+1. **Установка Docker:** Необходимо убедиться, установлен ли Docker на системе, в ином случае установить его.
+2. **Навигация:** Перейти в директорию с файлом `docker-compose.yml`.
+3. **Запуск:** Необходимо выполнить следующую команду в терминале:
+   ```bash
+   docker-compose up --build --remove-orphans
+   ```
+   Данная команда создаст и запустит все необходимые контейнеры, описанные в `docker-compose.yml`.
+
+**Проверка:**
+
+Для проверки успешного запуска нужно выполнить команду:
+
+```bash
+docker ps -a
+```
+
+В случае успеха мы можем увидеть список запущенных контейнеров (gitea, postgres и redis):
+```bash

+```
+**Примечание:**
+
+*Файл `docker-compose.yml` содержит подробную информацию о конфигурации каждого сервиса, включая порты, тома и переменные окружения.*
+
+**Важно:**
+
+После первого запуска **Gitea**, необходимо зайти на сервис *(по адресу `http://localhost:3000`)*, выполнить первоначальную настройку и создать суперпользователя. 
+

+# Docker Compose: RabbitMQ, Mediawiki, Wordpress
+
+## Описание проекта
+
+Этот проект разворачивает три сервиса с помощью Docker Compose:
+1. **RabbitMQ** —  брокер сообщений.
+2. **Mediawiki** — движок вики.
+3. **Wordpress** — популярная система управления контентом.
+
+
+## Команды для запуска
+
+Из директории с файлом docker-compose.yml запустить сервисы docker-compose up --build
+
+## Сервисы и порты
+1. **RabbitMQ:**  
+   Доступ по адресу http://localhost:15672/ (логин: admin, пароль: admin).
+
+2. **Mediawiki:**  
+   Доступ по адресу http://localhost:8081/.

+# Отчет по лабораторной работе 1
+
+## Описание
+Docker Compose используется для одновременного управления несколькими контейнерами, входящими в состав приложения. Он позволяет хранить все настройки проекта в одном контейнере, что позволяет потом беспроблемно использовать те же настройки проекта на другом сервере. docker-compose.yml позволяет настраивать и документировать все зависимости служб приложения. В нем указываются образ, порт(который можно пробросить), окрущающие среды, томы и зависимости (если нужно). 
+
+## Описание docker-compose.yml
+Были выбраны следующие сервисы:
+
+1. Postgres
+2. Redmine
+3. Gitea
+
+В файле у каждого сервиса пробрасывается порт. Каждый сервис содержит том, который используются для хранения данных. Запуск Redmine и Gitea имеют зависимость от Postgres, чтобы они имели возможность накатить миграции и заполнить таблицы после создания базы. У каждого сервиса заполнен паарметр environment, где указываются данные для БД. 
+
+## Инструкция по запуску
+
+1. Запустить приложение Docker Hub
+2. Открыть консоль с помощью команды cd перейти к папке, где находится файл docker-compose.yml
+3. Ввести команду для поднятия контейнеров
+```
+docker compose up -d
+```
+Дожидаемся запуска сервисов:
+```
+[+] Running 3/3
+ ✔ Container yakovleva_julia_lab_1-postgres-1  Started                                                             0.5s

+```
+
+4. Убедиться, что сервисы успешно запущены можно по команде:
+```
+docker compose ps
+```
+Отобразится таблица с запущенными сервисами:
+```
+NAME                               IMAGE                COMMAND                  SERVICE    CREATED          STATUS         PORTS

+```
+
+Также можно посомтреть логи каждого севриса при вводе команды:
+```
+docker compose logs -ft (название сервиса)
+```
+-ft необходим для того, чтобы читать логи сервиса в реальном времени
