set¶

Patches configuration parameters for the autoscaling algorithm.

The coolDownPeriodSec specifies the number of seconds that the autoscaler should wait before it starts collecting information from a new instance.

The cpuUtilization.utilizationTarget specifies the target CPU utilization that the autoscaler should maintain.

The loadBalancingUtilization.utilizationTarget specifies fraction of backend capacity utilization (set in HTTP(S) load balancing configuration) that autoscaler should maintain.

The minNumReplicas specifies the minimum number of replicas that the autoscaler can scale down to.

The maxNumReplicas specifies the maximum number of instances that the autoscaler can scale up to.
