Pod Scaler

info

See also Pod Scaler reference

Pod Scaler is a basic building block of an auto-scaling policy for Kubernetes. It can scale out or scale in a Kubernetes Resources such as a Deployment. The component takes the desired replicas as an input signal and scales the underlying resources based on the value of the signal. To complete the feedback loop, the component emits output signals for the number of configured replicas and the actual number of replicas deployed.

A Pod Scaler component is not required if you are using the high-level Auto Scaler component. It defines multiple scale in, scale out controllers and takes care of instantiating the Pod Scaler component.
