type FitPredicate ¶

type FitPredicate func(pod *v1.Pod, meta interface{}, nodeInfo *schedulercache.NodeInfo) (bool, []PredicateFailureReason, error)

FitPredicate is a function that indicates if a pod fits into an existing node. The failure information is given by the error. TODO: Change interface{} to a specific type.

MetdataProducer is a function that computes metadata for a given pod.

type NodeLister ¶ added in v1.1.0

type NodeLister interface {
	// We explicitly return []*v1.Node, instead of v1.NodeList, to avoid
	// performing expensive copies that are unneeded.
	List() ([]*v1.Node, error)
}

NodeLister interface represents anything that can list nodes for a scheduler.

type PodLister ¶

type PodLister interface {
	// We explicitly return []*v1.Pod, instead of v1.PodList, to avoid
	// performing expensive copies that are unneeded.
	List(labels.Selector) ([]*v1.Pod, error)
}

	// TODO: Remove it after migrating all functions to
	// Map-Reduce pattern.
	Function PriorityFunction
	Weight   int
}

type PriorityFunction ¶

type PriorityFunction func(pod *v1.Pod, nodeNameToInfo map[string]*schedulercache.NodeInfo, nodes []*v1.Node) (schedulerapi.HostPriorityList, error)

DEPRECATED Use Map-Reduce pattern for priority functions.

type PriorityMapFunction ¶ added in v1.5.0

type PriorityMapFunction func(pod *v1.Pod, meta interface{}, nodeInfo *schedulercache.NodeInfo) (schedulerapi.HostPriority, error)

type PriorityReduceFunction ¶ added in v1.5.0

type PriorityReduceFunction func(pod *v1.Pod, meta interface{}, nodeNameToInfo map[string]*schedulercache.NodeInfo, result schedulerapi.HostPriorityList) error

PriorityReduceFunction is a function that aggregated per-node results and computes final scores for all nodes. TODO: Figure out the exact API of this method. TODO: Change interface{} to a specific type.

type ReplicaSetLister ¶ added in v1.2.0

type ReplicaSetLister interface {
	// Gets the replicasets for the given pod
	GetPodReplicaSets(*v1.Pod) ([]*extensions.ReplicaSet, error)
}

ReplicaSetLister interface represents anything that can produce a list of ReplicaSet; the list is consumed by a scheduler.

	Schedule(*v1.Pod, NodeLister) (selectedMachine string, err error)
}

ScheduleAlgorithm is an interface implemented by things that know how to schedule pods onto machines.

type SchedulerExtender ¶ added in v1.2.0

type SchedulerExtender interface {
	// Filter based on extender-implemented predicate functions. The filtered list is
	// expected to be a subset of the supplied list. failedNodesMap optionally contains
	// the list of failed nodes and failure reasons.
	Filter(pod *v1.Pod, nodes []*v1.Node, nodeNameToInfo map[string]*schedulercache.NodeInfo) (filteredNodes []*v1.Node, failedNodesMap schedulerapi.FailedNodesMap, err error)

	// Prioritize based on extender-implemented priority functions. The returned scores & weight
	// are used to compute the weighted score for an extender. The weighted scores are added to
	// the scores computed  by Kubernetes scheduler. The total scores are used to do the host selection.
	Prioritize(pod *v1.Pod, nodes []*v1.Node) (hostPriorities *schedulerapi.HostPriorityList, weight int, err error)
