Why is there an error in Horizontal Pod Autoscaler Yaml?-CodePudding

2022-08-17T16:14:15.5682728Z error: error validating "deployment.yml": error validating data: ValidationError(HorizontalPodAutoscaler.spec.metrics[1].resource.target.averageUtilization): invalid type for io.k8s.api.autoscaling.v2.MetricTarget.averageUtilization: got "string", expected "integer"; if you choose to ignore these errors, turn validation off with --validate=false

I tried the memory "averageUtilization" values with 1.5Gi and "1.5Gi" with double quotes. Can anyone check and let me know if I am missing something here?

CodePudding user response：

averageUtilization:

is represented as a percent of requested memory. So you're wrong with Mi.

It should be.

averageUtilization: 65

Specify averageUtilization and a target average memory utilization over all the pods, represented as a percent of requested memory. The target pods must have memory requests configured.

CodePudding user response：

In deployment yaml, expecting "integer",

averageUtilization: "1500Mi"

  - type: Resource
    resource:
      name: memory
      target:
        type: Utilization
        averageUtilization: "1500Mi"

Update this in your yaml file and deploy in kubernetes. FYI: https://kubernetes.io/docs/tasks/administer-cluster/manage-resources/quota-memory-cpu-namespace/
