Worked on enhancing container security and reliability for the PlexTrac/plextrac-manager-util repository by standardizing ownership and permissions for the localesOverride volume within Docker Compose environments. Addressed deployment consistency and security by applying explicit octal permissions and ensuring the locale directory remained writable for the application user, reducing the risk of unauthorized access and locale-related outages. Leveraged skills in DevOps, Docker, and shell scripting to implement these changes, focusing on system administration best practices. The work improved maintainability and runtime behavior for Dockerized deployments, providing a more robust foundation for managing file permissions and access control in production environments.
