The portal kind of hid this away because in the first step, it would actually create one for you and then just use that to create the cluster. If the resource type is any other value, the autoscaler expects this metric to contain values that apply to the entire autoscaled instance group and resource label filtering can be performed to point autoscaler at the correct TimeSeries to scale upon. Horizontal Pod Autoscaler automatically scales the number of pods in a replication controller, deployment or replica set based on observed CPU utilization. Autoscalers allow you to automatically scale virtual machine instances in managed instance groups according to an autoscaling policy that you define.
