Ansible: как удалить/восстановить файл при запуске Ansible Playbook?
Опубликовано: 2019-08-29
Ansible, без сомнения, лучший инструмент автоматизации инфраструктуры, который используется ведущими компаниями из списка Fortune 500 по всему миру.
На Crunchify мы опубликовали множество руководств по Ansible. Пожалуйста, взгляните на Ansible Archive для всех подробных руководств. Вот 3 лучших урока.
- Как скопировать файл, каталог или скрипт с локального хоста на удаленный хост?
- Как создавать виртуальные машины Amazon EC2 с помощью Ansible?
- Как выполнять команды на удаленных хостах и возвращать результат команды (журнал)?
В этом уроке мы рассмотрим 3 разных совета, которые я использую повседневно.
Как удалить и заново создать файл с помощью Ansible?
Шаг 1
Убедитесь, что вы правильно настроили Ansible на своем Mac или ОС Linux.
Шаг 2
Создать файл crunchify-delete-recreate-ansible.yml

Шаг 3
Откройте файл hosts и поместите ниже содержимое:

[ local ] localhost ansible_connection = local ansible_python_interpreter = python |
Шаг-4

Запустите Ansible playbook .

1 |
ansible - playbook - vvv - i . / hosts crunchify - delete - recreate - ansible . yml |
Вот результат:

Вот и все. Над Ansible playbook удалит существующий файл с именем crunchify.txt и создаст новый с пустым содержимым.

Как обычно, сообщите нам о любом запросе или любой проблеме, запущенной выше Ansible Playbook.
