KubeSim analysis framework

Intro

kubesim provides a virtual kubernetes cluster interface for evaluating your scheduler. As new pods get scheduled on nodes in a cluster, more resources get consumed.Monitoring available resources and scheduler rules in the cluster is very important as operators can increase the current resources in time before all of them get exhausted.Or, carry different steps that lead to increase of available resources.
