Ansible Conditionals – When, Register & Other Examples

Ansible conditionals allow users to make decisions based on predefined criteria such as the state of systems and environments, enhancing control over automation tasks. Conditionals can be used for various purposes like inputting certain variables based on environment, kicking off DB backups only when disk space usage is above a certain threshold, triggering reboots if files were changed or updated, adding or modifying users based on roles and departments, skipping tasks under certain conditions, and notifying teams if tasks related to their team were added or modified. There are different types of Ansible conditionals including simple conditions, registered variables conditions, Ansible facts conditions, and logical operators like AND, OR, and NOT. These conditionals can be used in conjunction with the when statement and the register statement for more precise control over playbook task execution.
