Functions ¶

func New ¶

func New(_ *runtime.Unknown, h framework.FrameworkHandle) (framework.Plugin, error)

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

PodTopologySpread is a plugin that ensures pod's topologySpreadConstraints is satisfied.

func (*PodTopologySpread) Filter ¶

func (pl *PodTopologySpread) Filter(ctx context.Context, cycleState *framework.CycleState, pod *v1.Pod, nodeInfo *nodeinfo.NodeInfo) *framework.Status

Filter invoked at the filter extension point.

func (*PodTopologySpread) Name ¶

func (pl *PodTopologySpread) Name() string

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

func (*PodTopologySpread) NormalizeScore ¶

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

NormalizeScore invoked after scoring all nodes.

func (*PodTopologySpread) Score ¶

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

Score invoked at the Score extension point. The "score" returned in this function is the matching number of pods on the `nodeName`, it is normalized later.

func (*PodTopologySpread) ScoreExtensions ¶

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

ScoreExtensions of the Score plugin.
