Домашнее задание к занятию "3. Использование Yandex Cloud"

Подготовка к выполнению

  1. Подготовьте в Yandex Cloud три хоста: для clickhouse, для vector и для lighthouse.

Ссылка на репозиторий LightHouse: https://github.com/VKCOM/lighthouse

Основная часть

  1. Допишите playbook: нужно сделать ещё один play, который устанавливает и настраивает lighthouse.
  2. При создании tasks рекомендую использовать модули: get_url, template, yum, apt.
  3. Tasks должны: скачать статику lighthouse, установить nginx или любой другой webserver, настроить его конфиг для открытия lighthouse, запустить webserver.
  4. Приготовьте свой собственный inventory файл prod.yml.

  1. Подготовьте README.md файл по своему playbook. В нём должно быть описано: что делает playbook, какие у него есть параметры и теги.

Ссылка на readme файл [https://github.com/Firewal7/devops-netology/blob/main/08-ansible-03-yandex/README.md]

  1. Готовый playbook выложите в свой репозиторий, поставьте тег 08-ansible-03-yandex на фиксирующий коммит, в ответ предоставьте ссылку на него.

[https://github.com/Firewal7/devops-netology/blob/08-ansible-03-yandex/08-ansible-03-yandex/site.yml]
