Kubernetes Cost Optimizer

Overview

This skill audits Kubernetes clusters for resource inefficiency by comparing requested CPU/memory against actual usage from metrics-server. It identifies zombie deployments, overprovisioned workloads, and generates kustomize-compatible patches for right-sizing with safety buffers.

Instructions

Step 1: Verify Cluster Access and Metrics Availability

Run kubectl cluster-info and kubectl top nodes to confirm connectivity and that metrics-server is running. If metrics-server is unavailable, inform the user and suggest installing it first.

Step 2: Collect Resource Data

For each namespace (or user-specified namespaces):

# Get resource requests/limits for all pods
kubectl get pods --all-namespaces -o json | jq '[.items[] | {
