February 2026 — NethermindEth/helm-charts: Delivered two feature enhancements to improve reliability and scheduling, with tests and documentation updates. 1) Pod Disruption Budget (PDB) support and validation adds PDB configuration with validations ensuring minAvailable or maxUnavailable are set and consistent with replica counts and autoscaling; tests verify behavior. 2) Anti-affinity presets for pod scheduling streamline placement and reflect usage in charts. No critical bugs fixed this month. Business value: safer upgrades, reduced downtime during maintenance, and more predictable scaling. Technologies demonstrated: Kubernetes scheduling concepts (PDB, anti-affinity), Helm chart development, test automation, and cross-repo collaboration between generic-app and generic-app-p2p charts.
