Скачать или смотреть Ansible Error Handling

Error handling is an important part of any robust software system, but we often forget to consider error handling when designing operational automation systems. We frequently assume that our scripts and playbooks will always work, and we are left frustrated when failure creeps in and we aren't prepared to automatically handle it.

In this video, we take a look at error handling in Ansible. We look at three dimensions of error handling: task-level failures, host-level failures, and play-level failures. We consider different ways to handle errors at each of these levels, and we explore Ansible's behavior when various error handling parameters are properly set.
