Keda Manager

Status

Overview

Keda Manager is an extension to the Kyma runtime. It allows users to install KEDA. It follows the Kubernetes operator pattern to manage the lifecycle of the KEDA installation based on the existence and the content of the dedicated Keda custom resource (CR).

1. User applies the Keda CR.
2. Keda Manager watches the Keda CR.
3. Keda Manager reconciles the KEDA workloads.

For more information, see Use Keda Manager to manage KEDA.

What is KEDA?

KEDA is a flexible Event Driven Autoscaler for the Kubernetes workloads. It extends the Kubernetes autoscaling mechanisms with its own metric server and the possibility to make use of external event sources for making scaling decisions. To learn more about KEDA, see the KEDA documentation.
