Feb 1, 2025February 2025: Delivered key features and reliability improvements for the genestack project. Implemented Nginx Gateway API with a kustomize overlay (including stream support and disabled server tokens) and updated documentation to reflect Helm upgrade via kustomize overlays. Strengthened Ceilometer reliability by removing the deprecated ks_service job and ensuring notifications are acknowledged via RabbitMQ-backed URLs for Octavia and Magnum, reducing warning noise. Enhanced Ceilometer data handling by mapping volume_type to volume_type_id in Gnocchi and adding volume_id metadata to snapshots for easier resource association. These changes improve observability, upgrade readiness, and data fidelity while reducing operational risk. Technologies/skills demonstrated include Kubernetes tooling with kustomize overlays, Nginx Gateway API configuration, Helm upgrade workflows, Ceilometer reliability tuning, RabbitMQ-based notification reliability, and Gnocchi data model enhancements.
