May 2026 monthly summary for stackhpc development across kolla-ansible and kayobe-config. Focused on strengthening CI/CD reliability and reducing configuration risk via targeted automation and cleanup.

April 2026 monthly summary for stackhpc development focusing on feature delivery and release automation across two repositories. Key features delivered: - Multipathd Kolla Container Images Support: Added build support for multipathd-enabled Kolla images in stackhpc-kayobe-config (commit 10e6cb45aacdcd2cda41f034b81d4182ed53e41e). This expands deployment capabilities for multi-path storage setups. - Release Automation Enhancements: In stackhpc-release-train, automated release workflow now promotes development container images to a release namespace, synchronizes package repositories, and integrates Slack notifications, with multipathd configuration added for Kolla images to improve storage management in containerized environments (commit 84e3721a5a51f6a453704bcf57b26bd3d1bccfe0). Major bugs fixed: - No explicit major defects documented in the provided scope for April 2026; effort focused on feature delivery and release automation. Overall impact and accomplishments: - Enhanced deployment capabilities with multipathd-enabled Kolla images, enabling more robust multi-path storage scenarios in containerized environments. - Streamlined release processes with automated image promotion, repository synchronization, and proactive alerts, reducing manual steps and improving release reliability and visibility. - Improved cross-team collaboration and stakeholder awareness via Slack notifications. Technologies/skills demonstrated: - Kolla container image integration, multipathd configuration, containerized deployments - Release automation and orchestration, CI/CD practices - Slack integrations for deployment visibility, packaging repository synchronization - Cross-repo collaboration and change management

September 2025: Delivered a safety-focused configuration guard in stackhpc-kayobe-config to ensure GPU PCI device configurations are only applied when gpu_group_map is defined, preventing unintended overrides of Nova API, compute, and scheduler configurations in Kayobe-managed OpenStack deployments. This fix mitigates risk in GPU passthrough setups and improves stability across OpenStack clusters.

January 2025 was focused on delivering enhanced observability for Ironic within the stackhpc-kayobe-config framework. The core delivery was the Ironic Prometheus Metrics Exporter integration, enabling Prometheus-based monitoring of Ironic workloads. The exporter was added to the configuration, with explicit image tagging, and included in the list of Kolla images deployed. Release notes indicate the exporter will be enabled by default under defined conditions, simplifying rollout and consistency across environments. This work positions us to improve capacity planning, SLA monitoring, and incident response with richer metrics.
