Master Rolling Updates with Ansible serial

Показать описание
I will teach you how to perform rolling updates and changes using the Serial option in Ansible. This is perfect for rolling changes while maintaining stability and uptime.

This example will use the Apache web service to demonstrate, but it can be applied to almost any module, operating system, etc.

If you want a video demonstrating a rolling OS upgrade, please let me know!
