Pausing the custom metrics autoscaler for a scaled object
You can pause and restart the autoscaling of a workload, as needed.
For example, you might want to pause autoscaling before performing cluster maintenance or to avoid resource starvation by removing non-mission-critical workloads.
Pausing a custom metrics autoscaler
You can pause the autoscaling of a scaled object by adding the autoscaling.keda.sh/paused-replicas annotation to the custom metrics autoscaler for that scaled object. The custom metrics autoscaler scales the replicas for that workload to the specified value and pauses autoscaling until the annotation is removed.
Procedure
-
Use the following command to edit the
ScaledObjectCR for your workload:$ oc edit ScaledObject scaledobject -
Add the
autoscaling.keda.sh/paused-replicasannotation with any value:apiVersion: keda.sh/v1alpha1 kind: ScaledObject metadata: annotations: autoscaling.keda.sh/paused-replicas: "4" (1) creationTimestamp: "2023-02-08T14:41:01Z" generation: 1 name: scaledobject namespace: my-project resourceVersion: '65729' uid: f5aec682-acdf-4232-a783-58b5b82f5dd01 Specifies that the Custom Metrics Autoscaler Operator is to scale the replicas to the specified value and stop autoscaling.
Restarting the custom metrics autoscaler for a scaled object
You can restart a paused custom metrics autoscaler by removing the autoscaling.keda.sh/paused-replicas annotation for that ScaledObject.
