Functions

func GenerateNodeMapAndSlice

func GenerateNodeMapAndSlice(nodes map[string]*api.NodeInfo) (map[string]*cache.NodeInfo, []*v1.Node)

GenerateNodeMapAndSlice returns the nodeMap and nodeSlice generated from ssn

func HaveAffinity

func HaveAffinity(pod *v1.Pod) bool

HaveAffinity checks pod have affinity or not

Types

type CachedNodeInfo

type CachedNodeInfo struct {
	Session *framework.Session
}

CachedNodeInfo is used in nodeorder and predicate plugin

func (*CachedNodeInfo) GetNodeInfo

func (c *CachedNodeInfo) GetNodeInfo(name string) (*v1.Node, error)

GetNodeInfo is used to get info of a particular node

type NodeLister

type NodeLister struct {
	Session *framework.Session
}

NodeLister is used in nodeorder plugin

func (*NodeLister) List

func (nl *NodeLister) List() ([]*v1.Node, error)

List is used to list all the nodes

type PodAffinityLister

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

PodAffinityLister is used to list pod with affinity

func (*PodAffinityLister) FilteredList

func (pal *PodAffinityLister) FilteredList(podFilter algorithm.PodFilter, selector labels.Selector) ([]*v1.Pod, error)

FilteredList is used to list all the pods with affinity under filter condition

func (*PodAffinityLister) List

func (pal *PodAffinityLister) List(selector labels.Selector) ([]*v1.Pod, error)

List method is used to list all the pods

type PodLister

type PodLister struct {
	Session *framework.Session

	CachedPods       map[api.TaskID]*v1.Pod
	Tasks            map[api.TaskID]*api.TaskInfo
	TaskWithAffinity map[api.TaskID]*api.TaskInfo
}

PodLister is used in predicate and nodeorder plugin

func NewPodLister

func NewPodLister(ssn *framework.Session) *PodLister

NewPodLister returns a PodLister generate from ssn

func (*PodLister) AffinityFilteredList

func (pl *PodLister) AffinityFilteredList(podFilter algorithm.PodFilter, selector labels.Selector) ([]*v1.Pod, error)

AffinityFilteredList is used to list all the pods with affinity under filter condition

func (*PodLister) AffinityLister

func (pl *PodLister) AffinityLister() *PodAffinityLister

AffinityLister generate a PodAffinityLister following current PodLister

func (*PodLister) FilteredList

func (pl *PodLister) FilteredList(podFilter algorithm.PodFilter, selector labels.Selector) ([]*v1.Pod, error)

FilteredList is used to list all the pods under filter condition

func (*PodLister) GetPod

func (pl *PodLister) GetPod(task *api.TaskInfo) *v1.Pod

GetPod will get pod with proper nodeName, from cache or DeepCopy keeping this function read only to avoid concurrent panic of map

func (*PodLister) List

func (pl *PodLister) List(selector labels.Selector) ([]*v1.Pod, error)

List method is used to list all the pods

func (*PodLister) UpdateTask

func (pl *PodLister) UpdateTask(task *api.TaskInfo, nodeName string) *v1.Pod

UpdateTask will update the pod nodeName in cache using nodeName NOT thread safe, please ensure UpdateTask is the only called function of PodLister at the same time.
