Dois problemas na verdade: 1 - Ao descrever o HPA havia o erro:
Warning FailedComputeMetricsReplicas 2m52s (x13 over 14m) horizontal-pod-autoscaler invalid metrics (1 invalid out of 1), first error is: failed to get cpu utilization: missing request for cpu Warning FailedGetResourceMetric 112s (x14 over 14m) horizontal-pod-autoscaler missing request for cpu
2- Após apagar o portal noticias deployment, percebi que os PODs eram criados mas não iniciados. Ficam com status running mas não estão executando (Ready 0) .
