Functions ¶
Types ¶
type SelectorSpread ¶
type SelectorSpread struct {
// contains filtered or unexported fields
}
SelectorSpread is a plugin that calculates selector spread priority.
func (*SelectorSpread) Name ¶
func (pl *SelectorSpread) Name() string
Name returns name of the plugin. It is used in logs, etc.
func (*SelectorSpread) NormalizeScore ¶
func (pl *SelectorSpread) NormalizeScore(ctx context.Context, state *framework.CycleState, pod *v1.Pod, scores framework.NodeScoreList) *framework.Status
NormalizeScore invoked after scoring all nodes. For this plugin, it calculates the score of each node based on the number of existing matching pods on the node where zone information is included on the nodes, it favors nodes in zones with fewer existing matching pods.
func (*SelectorSpread) PreScore ¶
func (pl *SelectorSpread) PreScore(ctx context.Context, cycleState *framework.CycleState, pod *v1.Pod, nodes []*v1.Node) *framework.Status
PreScore builds and writes cycle state used by Score and NormalizeScore.
func (*SelectorSpread) Score ¶
func (pl *SelectorSpread) 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 (*SelectorSpread) ScoreExtensions ¶
func (pl *SelectorSpread) ScoreExtensions() framework.ScoreExtensions
ScoreExtensions of the Score plugin.
