FAQ

How do I load variables from a file in Ansible?

Use ansible.builtin.include_vars: file=vars/myfile.yml. Variables are loaded at runtime and available for all subsequent tasks. For static loading at parse time, use vars_files in the play.

What is the difference between include_vars and vars_files?

vars_files loads at play parse time (static). include_vars loads at task runtime (dynamic) — meaning it can use variables in the filename and be wrapped in conditionals or loops.

Conclusion

The ansible.builtin.include_vars module is a versatile tool for load variables from files dynamically. Use the examples above as starting points and adapt them to your infrastructure needs.
