Ansible_python_interpreter máy chủ cục bộ

Thực hiện các tác vụ cục bộ là một hoạt động phổ biến khi làm việc với một loại API nào đó—các trường hợp sử dụng điển hình là dịch vụ đám mây, thiết bị mạng, quản lý cụm. Có ba cách để đạt được điều này trong Ansible.

4 về ưu điểm và nhược điểm, nhưng có thêm nhược điểm là một phong cách rất khác thường, thêm một hình phạt về khả năng đọc

Trong một bài viết trước tôi đã nói về mô hình người chạy cho phép sử dụng khoảng không quảng cáo tốt hơn cho các tình huống khác nhau ngay cả khi bộ điều khiển là máy chủ cục bộ.
