GKE Scheduler

I have some questions:

• If Minimum size in the node-pool is >0 the resize action will probably fail

• If autocscaling is on in the node-pool, I do not know what will happen with the reduction size command

@hungpv29 thanks for your questions:

1. zorya is changing the size of the underlying managed instance group and not the node pool itself, as far as I tested even if the minimum number is >0 it still works.

2. It is not recommended to use auto-scaling with zorya as it will probably scale the VM back up (it's is managed by GKE Cluster Autoscaler)
   If auto-scaling is a must, I suggest using Kube-Downsclaer it will enable you to downscale your Deployments, StatefulSets, and/or HorizontalPodAutoscalers during non-work hours and then the ClusterAutosclaer will go into effect and scale down the node-pool.
