Autoscaling in Openshift with Cluster Autoscaler and Machine Autoscaler

In my previous post, I covered how to scale compute (worker) nodes in OpenShift using a semi-automated approach. While OpenShift handled most of the heavy lifting—such as powering on the node via BMC, installing RHCOS, and joining the cluster—the scaling action itself still required manual intervention. This document focuses on removing that manual step altogether. Specifically, it explores how Cluster Autoscaler and Machine Autoscaler work together to enable automatic, workload-driven scaling o
