Overview
A pre-requisite, if we intend the autoscaler to monitor resource metrics, a source of resource metrics must be deployed. The simplest source of resource metrics is the metrics server.
The horizontal pod autoscalers works with a previously deployed higher level controller that supports scaling (deployments, replica sets, stateful sets).
