Cluster Autoscaler is not working in OCP 4

Solution Unverified - Updated -

Issue

  • After following the cluster autoscaler documentation, additional nodes are not being created when demand warrants.
  • A test pod was scaled sufficiently to create CPU pressure on the nodes and no additional node is created to schedule pods.
  • Scaling down does not work. I've reduced maxReplicas in the MachineAutoscaler and it has no effect.

Environment
