<p>I've got my HPA like this. The pods are scaling well but its not scaling down and the CPU utilization is just 5%. It is not scaling down to the minimum of 1 replica.</p>
<p>The below is my HPA</p>
<pre><code>apiVersion: autoscaling/v2beta2
kind: HorizontalPodAutoscaler
metadata:
  name: app
spec:
  scaleTargetRef:
    apiVersion: apps/v1
    kind: Deployment
    name: app
  minReplicas: 1
  maxReplicas: 10
  metrics:
  - type: Resource
    resource:
      name: cpu
      target:
        type: Utilization
        averageUtilization: 70
  - type: Resource
    resource:
      name: memory
      target:
        type: AverageValue
        averageValue: 100Mi
</code></pre>

<p>In the above yaml file, I was using two resources as shown below</p>
<pre><code>metrics:
  - type: Resource
    resource:
      name: cpu
      target:
        type: Utilization
        averageUtilization: 70
  - type: Resource
    resource:
      name: memory
      target:
        type: AverageValue
        averageValue: 100Mi
</code></pre>
<p>The memory resource was not quickly released by the application and once I removed the memory resource the pods scaled down when the utilization was less.</p>
