Types

type Node 

type Node struct {

	// This field is set when inserting the Node into a NodeDb.
	Keys [][]byte

	AllocatableByPriority map[int32]ResourceList
	AllocatedByQueue      map[string]ResourceList
	AllocatedByJobId      map[string]ResourceList
	EvictedJobRunIds      map[string]bool
	// contains filtered or unexported fields
}

Node is a scheduler-internal representation of one Kubernetes node. Its private fields should be immutable! Do not change these!
