Scaling To and From Zero

Custom Pod Autoscalers can scale to and from zero; it is dependent on the minReplicas configuration option.

Disable Scale to Zero

If the minReplicas configuration option is set to anything but 0 scaling to zero is disabled; if the replica count of a resource being managed is set to 0 it will be treated as autoscaling disabled and the CPA will not scale it up or down.

Enable Scale to Zero

If the minReplicas configuration option is set to 0 scaling to and from 0 is enabled, allowing the autoscaler to set the replica count to 0 and then back up again.
