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 {
	// contains filtered or unexported fields
}

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.

func (*Fit) PreFilter ¶

func (f *Fit) PreFilter(ctx context.Context, cycleState *framework.CycleState, pod *v1.Pod) *framework.Status

PreFilter invoked at the prefilter extension point.

func (*Fit) PreFilterExtensions ¶

func (f *Fit) PreFilterExtensions() framework.PreFilterExtensions

PreFilterExtensions returns prefilter extensions, pod add and remove.

type FitArgs ¶

type FitArgs struct {
	// IgnoredResources is the list of resources that NodeResources fit filter
	// should ignore.
	IgnoredResources []string `json:"IgnoredResources,omitempty"`
}

FitArgs holds the args that are used to configure the plugin.

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
}

MostAllocated is a score plugin that favors nodes with high allocation based on requested resources.

func (*MostAllocated) Name ¶

func (ma *MostAllocated) Name() string

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

func (*MostAllocated) Score ¶

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