Worked on stabilizing the Pi-hole Web Admin interface within the nextcloud/all-in-one repository following the Pi-hole v6 upgrade. Addressed compatibility issues by updating container environment variables to match the new embedded webserver and configuration requirements. Utilized Shell scripting and containerization techniques to implement a stop/start workflow, ensuring that changes were applied with minimal downtime. Focused on DevOps practices to validate and reinforce the upgrade path, restoring admin UI functionality and maintaining deployment reliability for administrators. The work emphasized careful integration and testing, resulting in a more robust and reliable admin tooling experience across evolving versions of the Pi-hole service.
