I have created AKS cluster on Azure and created some deployments. Since one of my deployment required autoscaling i have enabled HPA on it, but it is not working. It is unable to get metrics from metrics server. Getting below error. Can some one help me on it?

Verify that the installation succeeded with:
kubectl get --raw=/apis/metrics.k8s.io/v1beta1Second, make sure that all the containers of your Deployment have CPU resource requests:
apiVersion: apps/v1
kind: Deployment
<...>
spec:
containers:
- image: foo
name: foo
resources:
requests:
cpu: 500mThird, configure the Horizontal Pod Autoscaler as you already did and observe the events.
