metadata:
  name: spring-api
spec:
  minReplicas: 1
  maxReplicas: 5
  metrics:
    - resource:
        name: cpu
        target:
          averageUtilization: 20
          type: Utilization
      type: Resource
  scaleTargetRef:
    apiVersion: apps/v1
    kind: Deployment
    name: spring-deployment #This should be the relevant deployment name
