Question

You are writing an Ansible playbook that deploys an updated Nginx configuration file with the 'template' module. Nginx should only be restarted when the configuration file actually changes, not on every playbook run. Which approach correctly implements this behavior?

Accepted Answer

Add 'notify: restart nginx' to the template task and define a handler named 'restart nginx' that restarts the service

Answer

Add a separate task that always runs 'service nginx restart' after the template task

Answer

Set 'changed_when: true' on the template task so Nginx restarts every time

Answer

Use the 'ignore_errors: yes' directive on the template task to force a restart
