Functions

func NewHighNodeUtilization

func NewHighNodeUtilization(args runtime.Object, handle framework.Handle) (framework.Plugin, error)

NewHighNodeUtilization builds plugin from its arguments while passing a handle

func NewLowNodeUtilization

NewLowNodeUtilization builds plugin from its arguments while passing a handle

Types

type HighNodeUtilization

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

func (*HighNodeUtilization) Balance

func (h *HighNodeUtilization) Balance(ctx context.Context, nodes []*v1.Node) *framework.Status

Balance extension point implementation for the plugin

func (*HighNodeUtilization) Name

func (h *HighNodeUtilization) Name() string

Name retrieves the plugin name

type LowNodeUtilization

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

func (*LowNodeUtilization) Balance

func (l *LowNodeUtilization) Balance(ctx context.Context, nodes []*v1.Node) *framework.Status

Balance extension point implementation for the plugin

func (*LowNodeUtilization) Name

func (l *LowNodeUtilization) Name() string

Name retrieves the plugin name

type NodeInfo

type NodeInfo struct {
	NodeUsage
	// contains filtered or unexported fields
}

type NodePodsMap

type NodePodsMap map[*v1.Node][]*v1.Pod

NodePodsMap is a set of (node, pods) pairs

type NodeThresholds

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

type NodeUsage

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

NodeUsage stores a node's info, pods on it, thresholds and its resource usage
