Worked on the stackhpc-kayobe-config repository to enhance deployment stability and security for Rocky Linux 9 environments. Over two months, delivered features focused on configuration management and system administration, using INI and YAML to update repository and container image configurations. Introduced Rocky Linux 9.6 support by pinning the default OS version and enabling vulnerability allowances for Prometheus exporters and InfluxDB, improving platform compatibility and observability security. Maintained deployment image currency by updating kolla and agent image tags, removing outdated components, and ensuring traceability through documented commits. These changes reduced operational risk and improved upgrade readiness for production OpenStack deployments.
