Functions

func InitializeNodePodCount

func InitializeNodePodCount(nodeList []*v1.Node) nodePodEvictedCount

InitializeNodePodCount initializes the nodePodCount.

func IsNodeAboveTargetUtilization

func IsNodeAboveTargetUtilization(nodeThresholds api.ResourceThresholds, thresholds api.ResourceThresholds) bool

func IsNodeWithLowUtilization

func IsNodeWithLowUtilization(nodeThresholds api.ResourceThresholds, thresholds api.ResourceThresholds) bool

func LowNodeUtilization

func LowNodeUtilization(ds *options.DeschedulerServer, strategy api.DeschedulerStrategy, evictionPolicyGroupVersion string, nodes []*v1.Node, nodepodCount nodePodEvictedCount)

func NodeUtilization

func NodeUtilization(node *v1.Node, pods []*v1.Pod) (api.ResourceThresholds, []*v1.Pod, []*v1.Pod, []*v1.Pod, []*v1.Pod, []*v1.Pod)

Nodeutilization returns the current usage of node.

func RemoveDuplicatePods

func RemoveDuplicatePods(ds *options.DeschedulerServer, strategy api.DeschedulerStrategy, policyGroupVersion string, nodes []*v1.Node, nodepodCount nodePodEvictedCount)

RemoveDuplicatePods removes the duplicate pods on node. This strategy evicts all duplicate pods on node. A pod is said to be a duplicate of other if both of them are from same creator, kind and are within the same namespace. As of now, this strategy won't evict daemonsets, mirror pods, critical pods and pods with local storages.

func RemovePodsViolatingInterPodAntiAffinity

func RemovePodsViolatingInterPodAntiAffinity(ds *options.DeschedulerServer, strategy api.DeschedulerStrategy, policyGroupVersion string, nodes []*v1.Node, nodePodCount nodePodEvictedCount)

RemovePodsViolatingInterPodAntiAffinity with elimination strategy

func RemovePodsViolatingNodeAffinity

func RemovePodsViolatingNodeAffinity(ds *options.DeschedulerServer, strategy api.DeschedulerStrategy, evictionPolicyGroupVersion string, nodes []*v1.Node, nodePodCount nodePodEvictedCount)

func SortNodesByUsage

func SortNodesByUsage(nodes []NodeUsageMap)

Types

type DuplicatePodsMap

type DuplicatePodsMap map[string][]*v1.Pod

func FindDuplicatePods

func FindDuplicatePods(pods []*v1.Pod) DuplicatePodsMap

FindDuplicatePods takes a list of pods and returns a duplicatePodsMap.

func ListDuplicatePodsOnANode

func ListDuplicatePodsOnANode(client clientset.Interface, node *v1.Node) DuplicatePodsMap

ListDuplicatePodsOnANode lists duplicate pods on a given node.

type NodePodsMap
