 The Kubernetes Scheduler is a crucial control plane component that determines which node a Pod will run on. 
 Thus, anyone utilizing Kubernetes relies on a scheduler.

 This tool allows users to closely examine the scheduler’s behavior and decisions. 
 
 It is useful for casual users who employ scheduling constraints (for example, [inter-Pod affinity](/docs/concepts/scheduling-eviction/assign-pod-node/#affinity-and-anti-affinity/#affinity-and-anti-affinity))

 The simulator allows users to create Kubernetes resources and observe how each plugin influences the scheduling decisions for Pods.
 This visibility helps users understand the scheduler’s workings and define appropriate scheduling constraints.

 Inside the simulator, a debuggable scheduler runs instead of the vanilla scheduler. 
 This debuggable scheduler outputs the results of each scheduler plugin at every extension point to the Pod’s annotations like the following manifest shows
