+**Задание**
+***
+Цель: изучение техники создания простого распределённого приложения.
+
+**Задачи**
+***
+
+Согласно варианту (0 и 1) разработать два приложения такие, что результат первого является исходными данными для второго.
+
+Изучить файлы сборки образов docker и разработать их для созданных приложений.
+
+Собрать файл docker-compose.yml для запуска приложений. Разобраться с монтированием каталогов из хост-системы.
+
+Правильно закоммитить результат без лишних файлов.
+
+Оформить pull request по правилам и отправить его на проверку.
+
+**Ход работы**
+***
+**Разворачивание сервисов:**
+***
+Были разработаны два приложения на java:
+
+worker-1 - Формирует файл /var/result/data.txt из файла, где было найдено самое большое число /var/data. 
+
+worker-2 - Ищет набольшее число из файла /var/result/data.txt и сохраняет его вторую степень в /var/result/result.txt.
+
+**Исходные файлы**
+
+Исходные файлы содержат целые числа.
+
+В /var/result/data.txt проверяются числа из каждого файла и выбирается самое большое
+
+**Firsttxt.txt:**
+1
+2
+3
+4
+5
+
+**Secondtxt.txt**
+1
+2
+3
+
+**Thirdtxt.txt**
+1
+2
+3
+4
+5
+6
+7
+8
+9
+10
+
+В /var/result/result.txt записывается число 100 - квадрат наибольшего числа - 10
+
+**Dockerfile**
+
+Для данной работы были созданы идентичные докер-файлы в обоих проектах.

+WORKDIR /app
+COPY src /app/src
+
+RUN javac /app/src/Main.java
+
+CMD ["java", "-cp", "/app/src", "Main"]
+````
+
+FROM - выбор базового образа
+
+RUN - создание директории внутри контейнера
+
+WORKDIR - установка рабочей директории для последующих команд
+
+COPY - копирование содержимого директории внутрь контейнера
+
+RUN - компиляция исходного кода Main.java внутри контейнера
+
+CMD - определение команды, которая выполняется при запуске контейнера. В данном случае происходит запуск программы на java и указывается пусть до Main.java

+## Задание
+
+Цель: изучение шаблона проектирования gateway, построения синхронного обмена между микросервисами и архитектурного стиля RESTful API.
+
+Задачи:
+
+- Создать 2 микросервиса, реализующих CRUD на связанных сущностях.
+- Реализовать механизм синхронного обмена сообщениями между микросервисами.
+- Реализовать шлюз на основе прозрачного прокси-сервера nginx.
+
+## Ход работы
+
+### Разворачивание сервисов:
+
+Были разработаны два приложения на Java с использованием средства автоматизации сборки проектов Gradle и с использованием библиотеки spring-boot:
+
+- categoryService - работа с дисциплинами (crud)
+- productService - работа с продуктами (crud). При создании продукта выбирается id категории, и через nginx и rest template происходит получение данных о категории с этим id
+
+### Обмен сообщениями
+При создании плана обучения выбирается id категории, и через nginx и rest template происходит получение данных о категории с этим id
+
+
+### Dockerfile
+Идентичные докерфайлы для приложений:
+```
+FROM openjdk:17
+RUN mkdir -p /usr/src/app/ 
+WORKDIR /usr/src/app/ 
+COPY . /usr/src/app/ 
+RUN ./gradlew clean build 
+EXPOSE 8089 
+ENTRYPOINT ["java","-jar","build/libs/lab3-0.0.1-SNAPSHOT.jar"]
+```
+### docker-compose.yml
+Файл, соединяющий сервисы (содержащий настройку Docker):
+```

+#   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/master/subprojects/plugins/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/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.

+# Лабораторная работа 4. Работа с брокером сообщений
+### Задание на лабораторную работу
+1. Установить брокер сообщений RabbitMQ.
+2. Пройти уроки 1, 2 и 3 из RabbitMQ Tutorials на любом языке программирования.
+3. Продемонстрировать работу брокера сообщений.
+
+***
+### Описание работы
+Были разработаны 3 приложения на *java*:
+1. **Publisher**. Программа, которая создаёт один *exchange* с типом *fanout* и раз в секунду генерирует сообщение.
+
+![](images/publisher.jpg)
+
+2. **Consumer1**. Программа, которая создаёт под себя отдельную не анонимную очередь (*queue1*), создаёт *binding* на
+*exchange* и начинает принимать сообщения. Программа обрабатывает сообщения 3 секунды.
+
+![](images/consumer1.jpg)
+
+3. **Consumer2**. Аналогично *Consumer1*, только сообщения обрабатываются моментально и имя очереди (*queue2*) 
+отличается от *Consumer1*.
+
+![](images/consumer2.jpg)

+* Пройти уроки 1, 2 и 3 из RabbitMQ Tutorials на любом языке программирования.
+* Продемонстрировать работу брокера сообщений.
+
+### Классы:
+ 1. ```Publisher``` - класс, отвечающий за отправку сообщений
+
+ 2. ```Consumer1``` - класс, отвечающий за принятие и обработку сообщений за задержкой 3 секунды
+
+ 2. ```Consumer2``` - класс, отвечающий за принятие и обработку сообщений без задержек
+
+#### Ход работы:
+ 
+На компьютер был установлен брокер сообщений ```RabbitMQ```, после чего все три класса программы были одновременно запущены.
+
+## Работа программы:
+
+Класс ```Publisher``` успешно осуществляет отправку сообщений своим клиентам.
+

+
+Класс ```Consumer1``` осуществляет принятие и обработку сообщений с задержкой в 3 секунды, это можно заметить на видео.
+
+![](Consumer1.png "")
+
+Класс ```Consumer2``` мгновенно осуществляет принятие и обработку сообщений.

+# Лабораторная работа №1 - Знакомство с docker и docker-compose
+
+Цель: изучение современных технологий контейнеризации.
+
+Задачи:
+
+Установить средство контейнеризации docker.
+Изучить применение и принципы docker.
+Изучить утилиту docker-compose и структуру файла docker-compose.yml.
+Развернуть не менее 3х различных сервисов при помощи docker-compose.
+Оформить отчёт в формате Markdown и создать Pull Request в git-репозитории.
+
+# Необходимо развернуть три сервиса
+
+Были выбраны сервисы:
+
+- mediawiki - движок вики
+- wordpress - популярная система управления контентом.
+- drupal - популярная система управления контентом
+- mariadb - база данных для mediawiki
+
+# Запуск
+
+Запуск контейнеров производится командой "docker-compose up -d" или через UI IDE
+
+# Работы программы
+
+- Был создан docker-compose.yml файл, в котором были описаны сервисы с различными настройками ![image_docker_compose.png](image_docker_compose.png)
+- Сборка и запуск контейнеров ![image_started_containers.png](image_started_containers.png)
+- Отображение запущенных контейнеров в Docker Desktop ![image_docker_desktop.png](image_docker_desktop.png)
+- Проверяем работу каждого сервиса:
+- Drupal ![image_drupal.png](image_drupal.png)
+- Mediawiki ![image_mediawiki.png](image_mediawiki.png)
+- WordPress ![image_wordpress.png](image_wordpress.png)
