Grzegorz worked on the stackhpc-kayobe-config repository, focusing on enhancing platform compatibility and deployment stability for Rocky Linux environments. Over two months, he delivered Rocky Linux 9.6 support by updating INI and YAML configuration files for repositories and container images, pinning the default OS version, and implementing security hardening for Prometheus exporters and InfluxDB. In the following month, he maintained deployment image tags, updating the kolla image and ensuring correct agent versions for OpenStack components. His work in configuration management and Linux system administration improved deployment reliability and traceability, addressing operational risk and upgrade readiness without introducing bug fixes.
