During April 2025, Daniel Semkowicz focused on stabilizing container deployment for the DivinumOfficium/divinum-officium repository by addressing SELinux-related permission issues in Docker environments. He updated the docker-compose.yml configuration to implement SELinux-aware volume mounts using the :Z relabeling option, ensuring correct file labeling and preventing permission-denied errors on SELinux-enabled systems. This solution was designed to be non-disruptive, maintaining compatibility across both SELinux and non-SELinux platforms. Daniel’s work leveraged his expertise in DevOps, Docker, and SELinux, resulting in improved deployment reliability and reduced support overhead related to container permissions, though his contributions were limited to bug fixes during this period.
