Summary of Changes

Hello @Alex-Welsh, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request addresses a configuration issue with Ansible's YAML output callback by updating the relevant parameter in the ansible.cfg files. Additionally, it introduces task profiling capabilities to assist with performance monitoring and debugging of Ansible playbooks, aiming to improve the reliability and observability of automation runs.

Highlights

• Ansible YAML Callback Fix: The stdout_callback parameter for YAML output has been updated to callback_result_format in both ansible.cfg files to align with newer Ansible versions and resolve a reported issue.
• Ansible Task Profiling: Task profiling has been explicitly enabled in terraform/github-runners/ansible.cfg by adding callbacks_enabled = ansible.posix.profile_tasks, providing a useful tool for performance analysis and debugging.

Code Review

This pull request updates Ansible configurations to fix an issue with the YAML callback and to enable task profiling. The change from stdout_callback to the built-in callback_result_format = 'yaml' is a good improvement that removes a dependency on the community.general collection in one case. My review focuses on a potential missing dependency introduced by enabling the profile_tasks callback. I've suggested making the dependency on the ansible.posix collection explicit in the requirements files to prevent potential runtime errors.
