  Autoscaling components for Kubernetes

  

This might be true for "stock" Kubernetes, but it seems likely that the grandparent post is using cluster autoscaling (since they mention "auto-scaled up"), for which this post is not accurate. The cluster-autoscaler component does remove nodes with low utilization and Pods fitting onto other nodes, effectively defragging the cluster. There's just plenty of reasons for it to not drain a node (as per its FAQ[1]). But it's highly configurable, so I wonder if the grandparent post just needed some configuration changes to suit their scenario better.
