The release notes for the Custom Metrics Autoscaler Operator for Red Hat OpenShift describe new features and enhancements, deprecated features, and known issues.

The Custom Metrics Autoscaler Operator uses the Kubernetes-based Event Driven Autoscaler (KEDA) and is built on top of the OKD horizontal pod autoscaler (HPA).

The Custom Metrics Autoscaler Operator for Red Hat OpenShift is provided as an installable component, with a distinct release cycle from the core OKD. The Red Hat OpenShift Container Platform Life Cycle Policy outlines release compatibility.

Custom Metrics Autoscaler Operator 2.17.2 release notes

Issued: 25 September 2025

This release of the Custom Metrics Autoscaler Operator 2.17.2 addresses Common Vulnerabilities and Exposures (CVEs). The following advisory is available for the Custom Metrics Autoscaler Operator:

Before installing this version of the Custom Metrics Autoscaler Operator, remove any previously installed Technology Preview versions or the community-supported version of Kubernetes-based Event Driven Autoscaler (KEDA).

New features and enhancements

The KEDA controller is automatically created during installation

The KEDA controller is now automatically created when you install the Custom Metrics Autoscaler Operator. Previously, you needed to manually create the KEDA controller. You can edit the automatically-created KEDA controller, as needed. For more information, see Editing the Keda Controller CR.

Support for the Kubernetes workload trigger

The Cluster Metrics Autoscaler Operator now supports using the Kubernetes workload trigger to scale pods based on the number of pods matching a specific label selector. For more information, see Understanding the Kubernetes workload trigger.

Support for bound service account tokens

The Cluster Metrics Autoscaler Operator now supports bound service account tokens. Previously, the Operator supported only legacy service account tokens, which are being phased out in favor of bound service account tokens for security reasons. For more information see Understanding custom metrics autoscaler trigger authentications.

Bug fixes

  • Previously, the KEDA controller did not support volume mounts. As a result, you could not use Kerberos with the Kafka scaler. With this fix, the KEDA controller now supports volume mounts. (OCPBUGS-42559)

  • Previously, the KEDA version in the keda-operator deployment object log reported that the Custom Metrics Autoscaler Operator was based on an incorrect KEDA version. With this fix, the correct KEDA version is reported in the log. (OCPBUGS-58129)
