## 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.
