‘Tries to move K8s Pods from on-demand to spot instances’:
K8s Spot rescheduler is a tool that tries to reduce load on a set of Kubernetes nodes. It was designed with the purpose of moving Pods scheduled on AWS on-demand instances to AWS spot instances to allow the on-demand instances to be safely scaled down (By the Cluster Autoscaler). In reality the rescheduler can be used to remove load from any group of nodes onto a different group of nodes. They just need to be labelled appropriately. For example, it could also be used to allow controller nodes to take up slack while new nodes are being scaled up, and then rescheduling those pods when the new capacity becomes available, thus reducing the load on the controllers once again.
