Specify the maximum number of of replicas to which the autoscaler can scale up

minintegerYes

1

Specify the minimal number of replicas to which the autoscaler can scale down

targetAPIVersionstringYes

"apps/v1"

Specify the apiVersion of scale target

targetKindstringYes

"Deployment"

Specify the kind of scale target

Template​

The following tabs display the definition's Cue template and the rendered YAML. The rendered YAML is the output of the Cue template when the definition is applied to a cluster.
