June 2025 — Yugabyte charts Key features delivered: - Hot-reload of root CA certificates in Helm-managed Kubernetes universes. Implemented by adding rootCAChecksum to values.yaml to enable conditional updates of the root CA certificate, preventing unnecessary pod restarts when certificate content hasn't changed. Major bugs fixed: - Stability improvement: reduces downtime by avoiding restarts when certs are unchanged (no separate bug count reported in this ticket). Overall impact and accomplishments: - Business value: lower operational toil, fewer disruptions during certificate rotations, and safer, faster deployments. - Technical accomplishments: Helm chart enhancement, YAML-driven config for certificate management, traceable through PLAT-17956 commit. Technologies/skills demonstrated: - Helm charts, Kubernetes certificate management, YAML configuration, Git-based change management. Commit reference: - 516ebcf19e379a59a9aa8f909a38549cf80cf12f ([PLAT-17956]: Helm chart changes to support hot reload of certs on k8s universes.)

December 2024 monthly summary for yugabyte/charts. Delivered a critical bug fix in Pod Disruption Budget (PDB) policy template creation logic. The patch corrects a misrouting where useOldPodDisruptionBudget did not determine PDB policy creation, and instead was tied to API version selection. The service.yaml template logic was adjusted to ensure the PDB policy is created only when intended by configuration, improving deployment reliability across environments. Commit f49293b9497df954be5266132bf5f0d29a58bb10 [PLAT-16260] documents the change.
