Whenever I create an HPA, it always shows the TARGET as /3% or similar.
I have metrics-server running in kube-system (created by helm install metrics-server), and when I do a kubectl top nodes I get data back (with no unknowns) as well as when I do a kubectl get --raw "/apis/metrics.k8s.io/"
How can I debug this issue?
