Variable precedence in Ansible

by XDK 24. September 2019 05:41

Explanation:

Following are the levels of variable precedence arranged from the least (always gets overridden) to the most (can override anything below it):
1. Role defaults
2. Inventory files (host_vars > group_vars > vars)
3. Playbook group_vars
4. Playbook host_vars
5. Host facts
6. Variables files > vars_prompt > vars
7. Variables created using the register clause
8. Variables files created inside Roles and those set by the include_vars module
9. Variables defined in a block
10. Variables defined in a task block
11. Any variables passed through -e during command execution
