Veneer is a Kubernetes controller that optimizes Karpenter provisioning decisions using real-time cost data. It manages NodeOverlay resources based on AWS Reserved Instance and Savings Plans data from Lumina — steering Karpenter toward the most cost-effective instance types.
Cost-Aware Scheduling
Automatically creates and manages Karpenter NodeOverlay resources to prioritize instance types covered by Reserved Instances and Savings Plans.
Real-Time Optimization
Continuously reconciles with Lumina’s cost metrics to keep provisioning decisions aligned with your current RI/SP capacity and utilization.
Seamless Karpenter Integration
Works alongside Karpenter’s existing bin-packing and scheduling logic. Veneer influences instance selection without replacing Karpenter’s core functionality.
