Manual

Add new Cluster Node

1. Зарезервировать IP адрес для Cluster Node на Router по MAC (http://192.168.0.1/).
2. Добавить новую Cluster Node в Ansible inventory (https://github.com/rakovets/env-paas).
3. Раскатить необходимое ПО для Cluster Node с помощью Ansible (https://github.com/rakovets/env-paas).
   • Предварительно добавить sudo пароль для первичной инициализации
   • Проинициализировать
   • Раскатить ПО
4. Добавить новую Cluster Node на сетевую диаграмму.

Backlog

• Создать boilerplate для проекта
• В RCLI добавить создание нового сервиса:
  • создает git-repository на основе boilerplate
• Добавить CLI-complete for RCLI
