+# Лабораторная работа №3 - REST API, Gateway и синхронный обмен между микросервисами
+**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 ЯП Java с использованием средства автоматизации сборки проектов Gradle и с использованием библиотеки spring-boot:
+* client - содержит работу с записями по пользователям мобильного приложения для поддержки здоровья.
+* training - содержит работу с записями по тренировкам пользователей. Каждая тренировка относится к единственному пользователю, у пользователя может быть много тренировок (связь многие к одному). 
+### Обмен сообщениями
+При чтении (создании, обновлении) записи тренировки при помощи RestTemplate по id клиента мы получаем его данные. Пример с методом создания тренировки:

+### Dockerfile
+Были созданы идентичные докер-файлы для приложений :
+```
+FROM openjdk:17 #базовый образ
+RUN mkdir -p /usr/src/app/ #создание директории
+WORKDIR /usr/src/app/ #установка рабочей директории проекта
+COPY . /usr/src/app/ #копирование файлов с хоста в контейнер
+RUN ./gradlew clean build #сборка проекта
+EXPOSE 8089 #объявление порта
+ENTRYPOINT ["java","-jar","build/libs/labIP-0.0.1-SNAPSHOT.jar"] #точка входа для контейнера
+```
+### nginx.conf
+Были созданы идентичные докер-файлы для приложений :
+```
+http {
+    server {
+        listen 80; #запросы по порту 80 для IPv4
+        listen [::]:80; #запросы по порту 80 для IPv6
+        server_name localhost; #имя сервера
+
+        location /client/ {  #настройки для запросов, поступающих по пути /client/
+            proxy_pass http://client:8089/; #прокси-перенаправление на адрес
+            proxy_set_header Host $host; #установка дополнительных HTTP-заголовков
+            proxy_set_header X-Real-IP $remote_addr;
+            proxy_set_header X-Forwarded-Proto $scheme;
+            proxy_set_header X-Forwarded-Prefix /client;
+        }
+
+        location /training/ { #настройки для запросов, поступающих по пути /training/ 
+            proxy_pass http://training:8090/; #прокси-перенаправление на адрес

+            proxy_set_header X-Real-IP $remote_addr;
+            proxy_set_header X-Forwarded-Proto $scheme;
+            proxy_set_header X-Forwarded-Prefix /training;
+        }
+    }
+}
+
+events {
+    worker_connections  1024; #максимальное количество одновременных соединений для каждого рабочего процесса
+}
+```
+### docker-compose.yml
+Был создан файл docker-compose.yml для разворачивания сервисов:
+```
+version: "3" #формат конфигурации Docker Compose версии 3
+services: #определение сервисов
+  client:
+    build:
+      context: /client #путь к контексту сборки
+      dockerfile: Dockerfile #имя докерфайла
+    ports:
+      - "8089:8089" #проброс портов
+    networks: 
+      - netwrk #сеть
+    
+  training:
+    build:
+      context: /training #путь к контексту сборки
+      dockerfile: Dockerfile #имя докерфайла
+    ports:
+      - "8090:8090" #проброс портов
+    networks: 
+      - netwrk #сеть
+
+  nginx:
+    image: nginx:latest #образ для контейнера
+    ports:
+      - "8091:80" #проброс портов
+    networks: 
+      - netwrk #сеть
+    volumes:
+      - ./nginx.conf:/etc/nginx/nginx.conf #монтирует локальный файл конфигурации
+    depends_on: #зависимость от сервисов
+      - client
+      - training
+
+networks:
+  netwrk:
+    driver: bridge #изолированная сеть
+```

+#   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.
