# Заготовка для социальной сети
|
||||
Цель: В результате выполнения ДЗ вы создадите базовый скелет социальной сети, который будет развиваться в дальнейших ДЗ.
|
||||
|
||||
###В данном задании тренируются навыки:
|
||||
- декомпозиции предметной области;
|
||||
- построения элементарной архитектуры проекта
|
||||
Требуется разработать создание и просмотр анект в социальной сети.
|
||||
|
||||
###Функциональные требования:
|
||||
- Авторизация по паролю.
|
||||
- Страница регистрации, где указывается следующая информация:
|
||||
- Имя
|
||||
- Фамилия
|
||||
- Возраст
|
||||
- Пол
|
||||
- Интересы
|
||||
- Город
|
||||
- Страницы с анкетой.
|
||||
|
||||
###Нефункциональные требования:
|
||||
- Любой язык программирования
|
||||
- В качестве базы данных использовать MySQL
|
||||
- Не использовать ORM
|
||||
- Программа должна представлять из себя монолитное приложение.
|
||||
- Не рекомендуется использовать следующие технологии:
|
||||
- Репликация
|
||||
- Шардинг
|
||||
- Индексы
|
||||
- Кэширование
|
||||
|
||||
Верстка не важна. Подойдет самая примитивная.
|
||||
Разместить приложение на любом хостинге. Например, heroku.
|
||||
|
||||
ДЗ принимается в виде исходного кода на github и демонстрации проекта на хостинге.
|
||||
|
||||
Критерии оценки: Оценка происходит по принципу зачет/незачет.
|
||||
|
||||
###Требования:
|
||||
- Есть возможность регистрации, создавать персональные страницы, возможность подружиться, список друзей.
|
||||
- Отсутствуют SQL-инъекции.
|
||||
- Пароль хранится безопасно.

# Prometheus on EC2 & ECS:
|
||||
|
||||
Some helpers for anyone configuring Prometheus on ECS and AWS EC2.
|
||||
|
||||
To get started on AWS ECS and EC2:
|
||||
|
||||
*For EC2/ECS nodes*:
|
||||
- Import the ecs task definition and add cadvisor and node-exporter service/task definition and run them on each host you want to be monitored
|
||||
- Any hosts which have "Monitoring: On" tag will be automatically added in the targets
|
||||
- Expose ports 9100 and 9191 to your Prometheus host
|
||||
|
||||
*For Prometheus host*:
|
||||
|
||||
- Copy prometheus.yml configuration present here to base prometheus configuration to enable EC2 service discovery
|
||||
- `docker compose up -d`
|
||||
|
||||
**Note**:
|
||||
Set query.staleness-delta to 1m make metrics more realtime
|
||||
|
||||
|
||||
### TODO
|
||||
- Add alerting rules based on ECS

# Заготовка для социальной сети
|
||||
Цель: В результате выполнения ДЗ вы создадите базовый скелет социальной сети, который будет развиваться в дальнейших ДЗ.
|
||||
|
||||
###В данном задании тренируются навыки:
|
||||
- декомпозиции предметной области;
|
||||
- построения элементарной архитектуры проекта
|
||||
Требуется разработать создание и просмотр анект в социальной сети.
|
||||
|
||||
###Функциональные требования:
|
||||
- Авторизация по паролю.
|
||||
- Страница регистрации, где указывается следующая информация:
|
||||
- Имя
|
||||
- Фамилия
|
||||
- Возраст
|
||||
- Пол
|
||||
- Интересы
|
||||
- Город
|
||||
- Страницы с анкетой.
|
||||
|
||||
###Нефункциональные требования:
|
||||
- Любой язык программирования
|
||||
- В качестве базы данных использовать MySQL
|
||||
- Не использовать ORM
|
||||
- Программа должна представлять из себя монолитное приложение.
|
||||
- Не рекомендуется использовать следующие технологии:
|
||||
- Репликация
|
||||
- Шардинг
|
||||
- Индексы
|
||||
- Кэширование
|
||||
|
||||
Верстка не важна. Подойдет самая примитивная.
|
||||
Разместить приложение на любом хостинге. Например, heroku.
|
||||
|
||||
ДЗ принимается в виде исходного кода на github и демонстрации проекта на хостинге.
|
||||
|
||||
Критерии оценки: Оценка происходит по принципу зачет/незачет.
|
||||
|
||||
###Требования:
|
||||
- Есть возможность регистрации, создавать персональные страницы, возможность подружиться, список друзей.
|
||||
- Отсутствуют SQL-инъекции.
|
||||
- Пароль хранится безопасно.
