Google Kubernetes: worker pool not scaling down to zero
问题 I'm setting up a GKE cluster on Google Kubernetes Engine to run some heavy jobs. I have a render-pool of big machines that I want to autoscale from 0 to N (using the cluster autoscaler). My default-pool is a cheap g1-small to run the system pods (those never go away so the default pool can't autoscale to 0, too bad). My problem is that the render-pool doesn't want to scale down to 0. It has some system pods running on it; are those the problem? The default pool has plenty of resources to run
