@@ -7,12 +7,14 @@ a component of Kubernetes called kube-scheduler. The scheduler's decisions, whet
pod can or can not be scheduled, are guided by its configurable policy which comprises of set of
rules, called predicates and priorities. The scheduler's decisions are influenced by its view of
a Kubernetes cluster at that point of time when a new pod appears first time for scheduling.
As a Kubernetes cluster is very dynamic and its state changes over time, the initial scheduling
decision might turn out to be a sub-optimal one with respect to the cluster's ever changing state.
As a Kubernetes cluster is very dynamic and its state changes over time, the original scheduling
decisions might turn out to be a sub-optimal one with respect to the cluster's ever changing state.
Consequently, increasing population of pods scheduled on less desired nodes may lead to issues in
clusters for example performance degradation. Due to this, it becomes important to continuously
revisit initial scheduling decisions. This process of revisiting scheduling decisions and helping
some pods reschedule on other nodes is defined as rescheduling, and its implementation here as rescheduler.
