June 2025 focused on aligning Helm deployments with Caracal-based Neutron images. Delivered a targeted feature in sapcc/helm-charts by bumping the Neutron image version in Archer Helm chart values to caracal-latest, ensuring the neutron-linuxbridge-agent uses Caracal Neutron images. The change is committed as d915230e46f549611ad2fec67940cc63fb68c8ea ([archer] use caracal images for neutron-linuxbridge-agent). No major bugs fixed in this repository for the period. This update reduces deployment risk, improves image compatibility, and supports faster, more reliable rollouts for users relying on Caracal images.

May 2025 monthly summary focusing on delivering robust networking capabilities in sapcc/helm-charts and stabilizing Neutron deployments. Key achievements include enabling OVN-based networking for Neutron hypervisor agents, adding Calico-compatible externalTrafficPolicy configurability, and addressing deployment reliability through protocol handling and minor exposure fixes. Operational changes to alerting were implemented to reduce noise while preserving visibility.

April 2025 performance summary for sapcc/helm-charts. The team delivered a modular OVSDB deployment architecture by introducing dedicated OVSDB Helm charts and integrating OVN northd deployment, enabling clearer separation of concerns and more maintainable deployments. We also tightened the release process and stability by removing autoscaling on OVSDB deployments, fixing Helm lint issues, and correcting key DB_PORT configuration to prevent misconfigurations in Neutron charts.

Month: 2025-03 — The work focused on security hardening, observability, reliability improvements, and network deployment flexibility within sapcc/helm-charts. Key outcomes drive reduced attack surface, faster incident response, and more resilient deployments across availability zones.
