12.2. Autoscaling

An Autoscaler creates more instances of your pods when the need arises. In this lab we’ll adapt the steps in Kubernetes’ Horizontal Pod Autoscaling Walkthrough.

Add this resource to your deployment directory:

apiVersion: autoscaling/v2
kind: HorizontalPodAutoscaler
metadata:
  name: django
spec:
  scaleTargetRef:
    apiVersion: apps/v1
    kind: Deployment
    name: django
  minReplicas: 1
  maxReplicas: 10
  metrics:
  - type: Resource
    resource:
      name: cpu
      target:
        type: Utilization
        averageUtilization: 50
