Functions

func ConvertToPods

func ConvertToPods(objs []interface{}, filter FilterFunc) []*v1.Pod

func GroupByNamespace

func GroupByNamespace(pods []*v1.Pod) map[string][]*v1.Pod

func GroupByNodeName

func GroupByNodeName(pods []*v1.Pod) map[string][]*v1.Pod

func IsBestEffortPod

func IsBestEffortPod(pod *v1.Pod) bool

func IsBurstablePod

func IsBurstablePod(pod *v1.Pod) bool

func IsGuaranteedPod

func IsGuaranteedPod(pod *v1.Pod) bool

func ListAllPodsOnANode

func ListAllPodsOnANode(
	nodeName string,
	getPodsAssignedToNode GetPodsAssignedToNodeFunc,
	filter FilterFunc,
) ([]*v1.Pod, error)

ListAllPodsOnANode lists all the pods on a node no matter what the phase of the pod is.

func ListPodsOnANode

func ListPodsOnANode(
	nodeName string,
	getPodsAssignedToNode GetPodsAssignedToNodeFunc,
	filter FilterFunc,
) ([]*v1.Pod, error)

ListPodsOnANode lists all pods on a node. It also accepts a "filter" function which can be used to further limit the pods that are returned. (Usually this is podEvictor.Evictable().IsEvictable, in order to only list the evictable pods on a node, but can be used by strategies to extend it if there are further restrictions, such as with NodeAffinity).

func ListPodsOnNodes

func ListPodsOnNodes(nodes []*v1.Node, getPodsAssignedToNode GetPodsAssignedToNodeFunc, filter FilterFunc) ([]*v1.Pod, error)

ListPodsOnNodes returns all pods on given nodes.

func OwnerRef

func OwnerRef(pod *v1.Pod) []metav1.OwnerReference

OwnerRef returns the ownerRefList for the pod.

func OwnerRefUIDs

func OwnerRefUIDs(pod *v1.Pod) []string

func SortPodsBasedOnAge

func SortPodsBasedOnAge(pods []*v1.Pod)

SortPodsBasedOnAge sorts Pods from oldest to most recent in place

func SortPodsBasedOnPriorityLowToHigh

func SortPodsBasedOnPriorityLowToHigh(pods []*v1.Pod)

SortPodsBasedOnPriorityLowToHigh sorts pods based on their priorities from low to high. If pods have same priorities, they will be sorted by QoS in the following order: BestEffort, Burstable, Guaranteed

Types

type FilterFunc

type FilterFunc func(*v1.Pod) bool

FilterFunc is a filter for a pod.

func WrapFilterFuncs

func WrapFilterFuncs(filters ...FilterFunc) FilterFunc

WrapFilterFuncs wraps a set of FilterFunc in one.

type GetPodsAssignedToNodeFunc

type GetPodsAssignedToNodeFunc func(string, FilterFunc) ([]*v1.Pod, error)

GetPodsAssignedToNodeFunc is a function which accept a node name and a pod filter function as input and returns the pods that assigned to the node.

func BuildGetPodsAssignedToNodeFunc

func BuildGetPodsAssignedToNodeFunc(podInformer cache.SharedIndexInformer) (GetPodsAssignedToNodeFunc, error)

BuildGetPodsAssignedToNodeFunc establishes an indexer to map the pods and their assigned nodes. It returns a function to help us get all the pods that assigned to a node based on the indexer.

type Options

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

func NewOptions

func NewOptions() *Options

NewOptions returns an empty Options.

func (*Options) BuildFilterFunc

func (o *Options) BuildFilterFunc() (FilterFunc, error)

BuildFilterFunc builds a final FilterFunc based on Options.

func (*Options) WithFilter

func (o *Options) WithFilter(filter FilterFunc) *Options

WithFilter sets a pod filter. The filter function should return true if the pod should be returned from ListPodsOnANode

func (*Options) WithLabelSelector

func (o *Options) WithLabelSelector(labelSelector *metav1.LabelSelector) *Options

WithLabelSelector sets a pod label selector

func (*Options) WithNamespaces

func (o *Options) WithNamespaces(namespaces sets.Set[string]) *Options

WithNamespaces sets included namespaces

func (*Options) WithoutNamespaces

func (o *Options) WithoutNamespaces(namespaces sets.Set[string]) *Options

WithoutNamespaces sets excluded namespaces
