A library HPA targeting CPU utilization never changes replica counts. Investigation shows resource metrics are unavailable. What dependency is typically missing?
Select an answer to reveal the explanation.
Short Explanation
HPA looking at CPU without Metrics Server is like a thermostat with no thermometer—it cannot decide to heat or cool. Install the metrics path first.
Full Explanation
Resource-metric HorizontalPodAutoscalers rely on a metrics source such as Metrics Server to obtain Pod CPU and memory usage. LoadBalancer Services, arbitrary Ingress objects, or a PVC named metrics-server do not replace that metrics pipeline for HPA.
