Functions ¶

func CalcPrioritizeNodeScore ¶

func CalcPrioritizeNodeScore(info *nodeinfo.NodeInfo) (int, error)

CalcPrioritizeNodeScore simulates scheduler calculates the score.

Types ¶

func NewBalancer ¶

func NewBalancer(clientset kubernetes.Interface, recyclePeriod time.Duration, ratio float64) *Balancer

func (*Balancer) BalanceNodeRes ¶

func (b *Balancer) BalanceNodeRes(hostGSL *HostGSL)

We assume deleted pods schedule to outRightHosts and AddPod on them. When we RemovePod/AddPod it wil recalculate the score. STEP 1: resPressureOutLeftHostsMap delete pod one-by-one until the node score bigger than left. STEP 2: leftMeanHost rand delete pod one-by-one until outRightHostsMap.resFull is true.

func (*Balancer) PrioritizeNodes ¶

func (b *Balancer) PrioritizeNodes() (*HostGSL, error)

func (*Balancer) Run ¶

func (b *Balancer) Run(stopCh <-chan struct{})

type HostGSL ¶

type HostGSL struct {
	HostPriorityList schedulerapi.HostPriorityList
	// contains filtered or unexported fields
}

func (*HostGSL) Calc ¶

func (gsl *HostGSL) Calc()

func (*HostGSL) Mean ¶

func (gsl *HostGSL) Mean() float64

func (*HostGSL) Sd ¶

func (gsl *HostGSL) Sd() float64

func (*HostGSL) String ¶

func (gsl *HostGSL) String() string

type NodeInfoExt ¶

type NodeInfoExt struct {
	*nodeinfo.NodeInfo
	// contains filtered or unexported fields
}

func (*NodeInfoExt) AddPod ¶

func (n *NodeInfoExt) AddPod(pod *v1.Pod)

func (*NodeInfoExt) GetScore ¶

func (n *NodeInfoExt) GetScore() float64

func (*NodeInfoExt) RemovePod ¶

func (n *NodeInfoExt) RemovePod(pod *v1.Pod)
