infra-kubernetes-cost-optimizer

What problem does it solve?

It helps reduce Kubernetes infrastructure cost when cluster bills rise without matching workload growth, mainly by finding idle resources and correcting overly conservative resource requests.

Core Features & Use Cases

• Detect idle and wasted capacity: identifies zero-replica deployments, dormant workloads, and unused PVC/configurations that still consume budget.
• Quantify overprovisioning: compares declared CPU/memory requests against actual usage to reveal chronic over-requesting.
• Right-size safely with VPA/Goldilocks: generates data-driven recommendations for better request values, enabling efficient node packing and lower spend.
• Implement FinOps chargeback: supports namespace-level cost attribution using tools like OpenCost/Kubecost.
• Use cost controls: sets LimitRange and ResourceQuota defaults, and applies scheduled scale-down and spot strategies for appropriate workloads.

Quick Start

Install and run the optimizer by enabling Goldilocks in the target namespace (recommendation mode) and then review right-sized CPU/memory requests to reduce idle and overprovisioned capacity.
