Types

type BalancedAllocation

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

BalancedAllocation is a score plugin that calculates the difference between the cpu and memory fraction of capacity, and prioritizes the host based on how close the two metrics are to each other.

func (*BalancedAllocation) Name

func (ba *BalancedAllocation) Name() string

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

func (*BalancedAllocation) Score

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

Score invoked at the score extension point.

func (*BalancedAllocation) ScoreExtensions

func (ba *BalancedAllocation) ScoreExtensions() framework.ScoreExtensions

ScoreExtensions of the Score plugin.

type Fit

type Fit struct{}

Fit is a plugin that checks if a node has sufficient resources.

func (*Fit) Filter

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

Filter invoked at the filter extension point.

func (*Fit) Name

func (f *Fit) Name() string

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

type LeastAllocated

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

LeastAllocated is a score plugin that favors nodes with fewer allocation requested resources based on requested resources.

func (*LeastAllocated) Name

func (la *LeastAllocated) Name() string

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

func (*LeastAllocated) Score

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

Score invoked at the score extension point.

func (*LeastAllocated) ScoreExtensions

func (la *LeastAllocated) ScoreExtensions() framework.ScoreExtensions

ScoreExtensions of the Score plugin.

type MostAllocated

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