The MachineAutoscaler adjusts the number of Machines in the MachineSets that you
deploy in an {product-title} cluster. You can scale both the default worker
MachineSet and any other MachineSets that you create. The MachineAutoscaler
makes more Machines when the cluster runs out of resources to support more
deployments. Any changes to the values in MachineAutoscaler resources, such as
the minimum or maximum number of instances, are immediately applied
to the MachineSet they target.

|
You must deploy a MachineAutoscaler for the ClusterAutoscaler to scale your machines. The ClusterAutoscaler uses the annotations on MachineSets that the MachineAutoscaler sets to determine the resources that it can scale. If you define a ClusterAutoscaler without also defining MachineAutoscalers, the ClusterAutoscaler will never scale your cluster. |
