Jul 1, 2026July 2026 monthly recap for zalando-incubator/kubernetes-on-aws: Delivered a targeted autoscaling improvement for kubelet summary metrics. Increased the horizontal pod autoscaler max replicas from 10 to 20 to shorten scaling response times under variable demand. Implemented via commit bdf5d226adbb44ea93db2f5ee99288c865458197. Result: faster scale-out, better handling of traffic spikes, and improved workload stability in AWS deployments. No major bugs fixed this month.

Jul 1, 2025July 2025 monthly summary for zalando-incubator/kubernetes-on-aws. Focused on reliability, storage enablement, and cluster stability. Delivered three impactful changes that drive business value: (1) End-to-End Test Suite upgrade to Go 1.24, (2) AWS EFS-backed persistent storage for EKS, and (3) Scheduling stabilization by excluding the G6F instance family in Karpenter nodepools. These efforts reduce test noise, unlock persistent storage for stateful workloads, and improve cluster reliability, enabling faster release cycles and higher availability. Technologies demonstrated include Go 1.24, Kubernetes (EKS), AWS EFS, Karpenter, and infrastructure as code practices for feature flags and security groups.
