Configure autoscaling

This guide will cover how to configure KubeAI autoscaling parameters.

System Settings

KubeAI administrators can define system-wide autoscaling settings by setting the following Helm values (for the kubeai/kubeai chart):

Example:

# helm-values.yaml
modelAutoscaling:
  interval: 15s
  timeWindow: 10m
# ...

Model Settings

The following settings can be configured on a model-by-model basis.

Model settings: helm

If you are managing models via the kubeai/models Helm chart, you can use:

# helm-values.yaml
catalog:
  model-a:
    # ...
    minReplicas: 1
    maxReplicas: 9
    targetRequests: 250
    scaleDownDelaySeconds: 45
  model-b:
    # ...
    disableAutoscaling: true
# ...

Re-running helm upgrade with these additional parameters will update model settings in the cluster.

Model settings: kubectl

You can also specify the autoscaling profile directly via the Models custom resource in the Kubernetes API:

apiVersion: kubeai.org/v1
kind: Model
metadata:
  name: my-model
spec:
  # ...
  minReplicas: 1
  maxReplicas: 9
  targetRequests: 250
  scaleDownDelaySeconds: 45

If you are already managing models using Model manifest files, you can make the update to your file and reapply it using kubectl apply -f <filename>.yaml.
