Functions

func New

func New(_ context.Context, plArgs runtime.Object, h framework.Handle) (framework.Plugin, error)

New initializes a new plugin and returns it.

Types

type NodeAffinity

type NodeAffinity struct {
	// contains filtered or unexported fields
}

NodeAffinity is a plugin that checks if a pod node selector matches the node label.

func (*NodeAffinity) EventsToRegister

func (pl *NodeAffinity) EventsToRegister(_ context.Context) ([]framework.ClusterEventWithHint, error)

EventsToRegister returns the possible events that may make a Pod failed by this plugin schedulable.

func (*NodeAffinity) Filter

func (pl *NodeAffinity) Filter(ctx context.Context, state *framework.CycleState, pod *v1.Pod, nodeInfo *framework.NodeInfo) *framework.Status

Filter checks if the Node matches the Pod .spec.affinity.nodeAffinity and the plugin's added affinity.

func (*NodeAffinity) Name

func (pl *NodeAffinity) Name() string

Name returns name of the plugin. It is used in logs, etc.

func (*NodeAffinity) NormalizeScore

func (pl *NodeAffinity) NormalizeScore(ctx context.Context, state *framework.CycleState, pod *v1.Pod, scores framework.NodeScoreList) *framework.Status

NormalizeScore invoked after scoring all nodes.

func (*NodeAffinity) PreFilter

func (pl *NodeAffinity) PreFilter(ctx context.Context, cycleState *framework.CycleState, pod *v1.Pod) (*framework.PreFilterResult, *framework.Status)

PreFilter builds and writes cycle state used by Filter.

func (*NodeAffinity) PreFilterExtensions

func (pl *NodeAffinity) PreFilterExtensions() framework.PreFilterExtensions

PreFilterExtensions not necessary for this plugin as state doesn't depend on pod additions or deletions.

func (*NodeAffinity) PreScore

func (pl *NodeAffinity) PreScore(ctx context.Context, cycleState *framework.CycleState, pod *v1.Pod, nodes []*framework.NodeInfo) *framework.Status

PreScore builds and writes cycle state used by Score and NormalizeScore.

func (*NodeAffinity) Score

func (pl *NodeAffinity) Score(ctx context.Context, state *framework.CycleState, pod *v1.Pod, nodeName string) (int64, *framework.Status)

Score returns the sum of the weights of the terms that match the Node. Terms came from the Pod .spec.affinity.nodeAffinity and from the plugin's default affinity.

func (*NodeAffinity) ScoreExtensions

func (pl *NodeAffinity) ScoreExtensions() framework.ScoreExtensions

ScoreExtensions of the Score plugin.
