+# Отчет. Лабораторная работа 1
+
+В рамках лабораторной работы с помощью технологии контейнеризации docker были развернуты сервисы:
+- Redmine - система баг-трекинга
+- Postgres - СУБД
+- RabbitMQ - брокер сообщений
+
+## Описание 
+В docker-compose.yml файле описаны настройки для запуска трех выбранных сервисов в контейнерах. Для большинства строк файла оставлены 
+комментарии, объясняющие содержимое файла.
+
+Стоит отметить, для сервиса Redmine было принято решение в качестве сервера баз данных не использовать базу данных по умолчанию - SQLite, 
+а поднять внешний сервер баз данных Postgres, который был запущен в рамках этого же файла docker-compose.yml.
+
+Для того, чтобы при старте postgres уже была создана база данных для Redmine, а также пользователь, под учетной записью 
+которого будет работать Redmine, был написан скрипт init-database.sh с использованием bash и sql:
+```
+# Создаем пользователя redmine и БД redminedb
+psql -v ON_ERROR_STOP=1 --username "$POSTGRES_USER" --dbname "$POSTGRES_DB" <<-EOSQL
+    CREATE USER redmine WITH PASSWORD 'redmine-password';
+    CREATE DATABASE redminedb;
+    GRANT ALL PRIVILEGES ON DATABASE redminedb TO redmine;
+EOSQL
+
+# Даем права на схему public
+psql -v ON_ERROR_STOP=1 --username "$POSTGRES_USERNAME" -d redminedb <<-EOSQL
+    ALTER SCHEMA public OWNER TO redmine;
+    GRANT ALL ON SCHEMA public TO redmine;
+EOSQL
+``` 
+
+Этот скрипт монтируется в директорию контейнера postgres ``docker-entrypoint-initdb.d``, которая является специальной точкой входа 
+для инициализации БД и содержит соответствующие скрипты.
+
+## Как запустить
+Для того, чтобы запустить сервисы, необходимо выполнить следующие действия:
+1. Установить и запустить Docker Engine или Docker Desktop (включает в себя Docker Engine и предоставляет UI) 
+2. Через консоль перейти в папку, в которой расположен файл docker-compose.yml
+3. Выполнить команду:
+```
+docker compose up -d
+```
+В случае успешного запуска всех контейнеров в консоли будет выведено следующее сообщение:
+```
+[+] Running 3/3 
+✔ Container rabbitmq  Started                                           0.8s
+✔ Container redmine   Started                                           1.2s
+✔ Container postgres  Started                                           0.5s 
+```
+Также будет создана папка postgres_data, которая монтируется в контейнере postgres
+
+Мы также можем увидеть статус всех запущенных контейнеров, если выполним команду:
+```
+docker ps
+```
+Или обратившись к логам каждого из контейнеров:
+``
+docker logs <container_name>
+``
+## Видео-отчет
+Работоспособность лабораторной работы можно оценить в следующем [видео](https://disk.yandex.ru/d/15QhUl3KQYSavA).

+# Docker Compose: PostgreSQL, RabbitMQ, Nginx
+
+## Описание проекта
+
+Этот проект разворачивает три сервиса с помощью Docker Compose:
+1. **PostgreSQL** — реляционная база данных.
+2. **RabbitMQ** — брокер сообщений с панелью управления.
+3. **Nginx** — веб-сервер и реверс-прокси.
+
+
+## Команды для запуска
+
+Чтобы развернуть и запустить проект, выполните следующие шаги:
+1. Убедитесь, что у вас установлен Docker и Docker Compose.
+2. Перейдите в директорию с файлом docker-compose.yml.
+3. Запустите сервисы командой: docker-compose up --build
+
+## Сервисы и порты
+1. **PostgreSQL:**  
+   **Порт:** 5432  
+   **Доступ:** Локально, через любые приложения, подключающиеся к базе данных PostgreSQL.
+
+
+2. **RabbitMQ:**  
+   **Порт для приложений:** 5672  
+   **Панель управления RabbitMQ:** Доступна по адресу [http://localhost:15672/](http://localhost:15672/) (логин: `user`, пароль: `password`).
+
+
+3. **Nginx:**  
+   **Порт:** 80  
+   **Назначение:** Используется как реверс-прокси для распределения трафика.

-## Задание
-
-1. Создать 2 микросервиса, реализующих CRUD на связанных сущностях.
-2. Реализовать механизм синхронного обмена сообщениями между микросервисами.
-3. Реализовать шлюз на основе прозрачного прокси-сервера nginx.
-
-Вариант: Продукты и история цен на них
-
-## Выполнение
-Были написаны два сервиса на языке java, фреймворк Spring:
-* Сервис price_module, хранящий данные о продуктах и реализующий CRUD операции с ними через HTTP запросы.
-* Сервис price_history_module, хранящий данные об истории цен на продукты и реализующий CRUD операции с ними через HTTP запросы.
-
-Сервисы синхронно сообщены - сервис истории цен при создании записи с ценой, посылает сообщение продукту на связывание.
-
-Для сервисов прописаны файлы Dockerfile, описывающие создание контейнеров:
-* Оба контейнера проявляют порты, на которых работает приложение: 8080 для продуктов и 8081 для истории цен.
-* Выбирается рабочая директория /app и туда копируются файлы скриптов.
-* Командой запускаются сами скрипты.
-
-Общий yaml-файл развёртки был настроен следующим образом:
-* блок services, где перечислены разворачиваемые сервисы.
-* для каждого сервиса прописан build, где объявляется его папка и докерфайл создания и зависимости.
-* для сервиса nginx прописан порт для отображения вовне.
-
-## Результат
-Демонстрация работы в видео.

-#   Gradle start up script for POSIX generated by Gradle.
-#
-#   Important for running:
-#
-#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
-#       noncompliant, but you have some other compliant shell such as ksh or
-#       bash, then to run this script, type that shell name before the whole
-#       command line, like:
-#
-#           ksh Gradle
-#
-#       Busybox and similar reduced shells will NOT work, because this script
-#       requires all of these POSIX shell features:
-#         * functions;
-#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
-#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
-#         * compound commands having a testable exit status, especially «case»;
-#         * various built-in commands including «command», «set», and «ulimit».
-#
-#   Important for patching:
-#
-#   (2) This script targets any POSIX shell, so it avoids extensions provided
-#       by Bash, Ksh, etc; in particular arrays are avoided.
-#
-#       The "traditional" practice of packing multiple parameters into a
-#       space-separated string is a well documented source of bugs and security
-#       problems, so this is (mostly) avoided, by progressively accumulating
-#       options in "$@", and eventually passing that to Java.
-#
-#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
-#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
-#       see the in-line comments for details.
-#
-#       There are tweaks for specific operating systems such as AIX, CygWin,
-#       Darwin, MinGW, and NonStop.
-#
-#   (3) This script is generated from the Groovy template
-#       https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
-#       within the Gradle project.

-#   Gradle start up script for POSIX generated by Gradle.
-#
-#   Important for running:
-#
-#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
-#       noncompliant, but you have some other compliant shell such as ksh or
-#       bash, then to run this script, type that shell name before the whole
-#       command line, like:
-#
-#           ksh Gradle
-#
-#       Busybox and similar reduced shells will NOT work, because this script
-#       requires all of these POSIX shell features:
-#         * functions;
-#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
-#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
-#         * compound commands having a testable exit status, especially «case»;
-#         * various built-in commands including «command», «set», and «ulimit».
-#
-#   Important for patching:
-#
-#   (2) This script targets any POSIX shell, so it avoids extensions provided
-#       by Bash, Ksh, etc; in particular arrays are avoided.
-#
-#       The "traditional" practice of packing multiple parameters into a
-#       space-separated string is a well documented source of bugs and security
-#       problems, so this is (mostly) avoided, by progressively accumulating
-#       options in "$@", and eventually passing that to Java.
-#
-#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
-#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
-#       see the in-line comments for details.
-#
-#       There are tweaks for specific operating systems such as AIX, CygWin,
-#       Darwin, MinGW, and NonStop.
-#
-#   (3) This script is generated from the Groovy template
-#       https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
-#       within the Gradle project.

+# Лабораторная работа 1
+Данная работа посвящена работе с docker compose и поднятию сервисов, необходимых для последующего выполнения работ.
+## Описание
+В качестве сервисов были выбраны:
+ - СУБД - Postgres
+ - Web интерфейс для БД Postgres - Adminer
+ - Брокер сообщений - RabbitMQ (+ Web интерфейс)
+## 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
+```
+В данном случае флаг `-d` не обязателен. Он лишь позволит оставить консоль интерактивной (запускает все контейнеры в фоновом режиме).  
+В случае, если в консоли отобразился подобный текст и появилась возможность вводить команды - сервисы успешно запущены.

+# Лабораторная работа 2
+Данная работа посвящена теме создания контейнеров из исходного кода посредства dockerfile, а так же взаимодействию сервисов через общие папки
+## Описание
+Был варана следующая комбинация вариантов:
+ - Первое приложение - 0-ой
+ - Второе приложение - 1-ый
+В результате, после запуска система изучит папку ./volumes/input, найдёт самый большой файл, а затем найдёт в нём самое большое число, выведя в директорию ./volumes/output файл с его квадратом. 
+Буфер же, по сути не имеет физического отображения на папку хоста.
+## 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 --build
+```
+В данном случае флаг `--build` заставит систему в любом случае собрать образы из исходников (даже если они уже есть). 
+В результате, после сборки оба сервиса запустятся и выведут в консоль логи примерно следующего содержания:
+## Описание dockerfile файла
+Подробное описание дано в виде комментариев в самом файле первого сервиса. Так как для разработки использовался .net 8.0, команд довольно много. При этом, так как второй сервис написан на той же платформе, особенных отличий двух docekrfile-ов нет(кроме пути
+## Описание compose файла
+Благодаря директиве `depends_on` в compose файле второй сервис будет ждать, пока не будет поднят первый сервис, и только потом начнёт подниматься. 
+Директива `build` позволяет использовать в compose не уже готовый образ, а тот, что будет собран непосредственно в момент запуска(если он уже существует и нет флага силовой сборки, будет использоваться существующий образ) 
+Область volumes позволяет создать буферную область. Эту папку можно монтировать как результирующую для первого сервиса и исходную - для второго
+## Видеодемонстрация
+Был записан видеоролик, демонстрирующий процесс запуска и работы сервисов. Он расположен по [адресу](https://drive.google.com/file/d/1sACiKx3_HRApa89a7LZFAZV05o7POhq6/view?usp=sharing)
