Aug 1, 2025Performance-review-ready summary for August 2025: Implemented a targeted reliability improvement for Metalk8s by tuning the NodeSystemSaturation alert threshold in the Prometheus configuration. The threshold was increased from 15 to 30 minutes to prevent premature alerts during transient high load, reducing alert noise and improving operator focus on sustained issues. Change scoped to the Prometheus Operator config inside the Metalk8s chart; committed as f94d0647d795c305028f04854b0e8da984e923c7 (MK8S-11). Technologies: Kubernetes, Prometheus/Prometheus Operator, Metalk8s chart, Git.

Mar 1, 2025In March 2025, the Metalk8s team focused on strengthening observability and release integrity. Key work includes delivering Thanos Query Service Discovery via ConfigMaps and file-based discovery with Helm integration, provisioning deployment scaffolding (empty ConfigMap) for service discovery, and rendering the Than os chart. Additionally, we corrected release metadata by reverting unintended changes to CHANGELOG and VERSION to ensure the patch version is accurate (0) and removed a development release entry. These efforts improve dynamic discovery, reduce manual configuration, and strengthen release governance, enabling scalable query workloads and smoother deployments.

Feb 1, 2025February 2025 (scality/metalk8s): Delivered key upgrade reliability improvements and release hygiene for the metalk8s project. Implemented a feature to ensure apiserver upgrades run on bootstrap nodes before other master nodes by sorting master nodes and prepending bootstrap nodes to the processing list, with accompanying changelog documentation. Performed changelog maintenance and dependency bumps for metalk8s-alert-logger to reflect Go 1.24 and Alertmanager 0.27.0, and updated build tooling to align image builds with these updates. These changes reduce upgrade risk, improve traceability, and strengthen compatibility across the cluster stack.

Jan 1, 2025January 2025: Delivered automated redeploy workflow for certificate renewal across critical services in scality/metalk8s. Salt-driven changes trigger re-generation of manifests and redeploy of Kubernetes components (controller-manager, scheduler), backup server, ingresses, Salt master, and Dex addon, enabling zero-downtime certificate rollovers. Also cleaned up release notes and changelog entries (128.0.1–128.0.3) to accurately reflect these redeploy improvements. Impact: improved uptime during cert renewals, reduced manual intervention, and clearer operator guidance. Technologies demonstrated: Salt, Kubernetes manifests, Dex, ingress management, and release documentation.
