Constants

❖
const (
    // DefaultMilliCPURequest defines default milli cpu request number.
    DefaultMilliCPURequest int64 = 100 // 0.1 core
    // DefaultMemoryRequest defines default memory request size.
    DefaultMemoryRequest int64 = 200 * 1024 * 1024 // 200 MB
)

For each of these resources, a pod that doesn't request the resource explicitly will be treated as having requested the amount indicated below, for the purpose of computing priority only. This ensures that when scheduling zero-request pods, such pods will not all be scheduled to the machine with the smallest in-use request, and that when scheduling regular pods, such pods will not see zero-request pods as consuming no resources whatsoever. We chose these values to be similar to the resources that we give to cluster addon pods (#10653). But they are pretty arbitrary. As described in #11713, we use request instead of limit to deal with resource requirements.

func ClearNominatedNodeName Uses

❖
func ClearNominatedNodeName(cs kubernetes.Interface, pods ...*v1.Pod) utilerrors.Aggregate

ClearNominatedNodeName internally submit a patch request to API server to set each pods[*].Status.NominatedNodeName> to "".

func DeletePod Uses

❖
func DeletePod(cs kubernetes.Interface, pod *v1.Pod) error

DeletePod deletes the given <pod> from API server

func GetEarliestPodStartTime Uses

❖
func GetEarliestPodStartTime(victims *extenderv1.Victims) *metav1.Time

GetEarliestPodStartTime returns the earliest start time of all pods that have the highest priority among all victims.

func GetNamespacesFromPodAffinityTerm Uses

❖
func GetNamespacesFromPodAffinityTerm(pod *v1.Pod, podAffinityTerm *v1.PodAffinityTerm) sets.String

GetNamespacesFromPodAffinityTerm returns a set of names according to the namespaces indicated in podAffinityTerm. If namespaces is empty it considers the given pod's namespace.

func GetNonzeroRequestForResource Uses

❖
func GetNonzeroRequestForResource(resource v1.ResourceName, requests *v1.ResourceList) int64

GetNonzeroRequestForResource returns the default resource request if none is found or what is provided on the request.

func GetNonzeroRequests Uses

❖
func GetNonzeroRequests(requests *v1.ResourceList) (int64, int64)

GetNonzeroRequests returns the default cpu and memory resource request if none is found or what is provided on the request.

func GetPodAffinityTerms Uses

❖
func GetPodAffinityTerms(affinity *v1.Affinity) (terms []v1.PodAffinityTerm)

GetPodAffinityTerms gets pod affinity terms by a pod affinity object.

func GetPodAntiAffinityTerms Uses

❖
func GetPodAntiAffinityTerms(affinity *v1.Affinity) (terms []v1.PodAffinityTerm)

GetPodAntiAffinityTerms gets pod affinity terms by a pod anti-affinity.

func GetPodFullName Uses

❖
func GetPodFullName(pod *v1.Pod) string

GetPodFullName returns a name that uniquely identifies a pod.

func GetPodStartTime Uses

❖
func GetPodStartTime(pod *v1.Pod) *metav1.Time

GetPodStartTime returns start time of the given pod or current timestamp if it hasn't started yet.

func IsScalarResourceName Uses

❖
func IsScalarResourceName(name v1.ResourceName) bool

IsScalarResourceName validates the resource for Extended, Hugepages, Native and AttachableVolume resources

func MoreImportantPod Uses

❖
func MoreImportantPod(pod1, pod2 *v1.Pod) bool

MoreImportantPod return true when priority of the first pod is higher than the second one. If two pods' priorities are equal, compare their StartTime. It takes arguments of the type "interface{}" to be used with SortableList, but expects those arguments to be *v1.Pod.

func NodesHaveSameTopologyKey Uses

❖
func NodesHaveSameTopologyKey(nodeA, nodeB *v1.Node, topologyKey string) bool

NodesHaveSameTopologyKey checks if nodeA and nodeB have same label value with given topologyKey as label key. Returns false if topologyKey is empty.

func PatchPod Uses

❖
func PatchPod(cs kubernetes.Interface, old *v1.Pod, new *v1.Pod) error

PatchPod calculates the delta bytes change from <old> to <new>, and then submit a request to API server to patch the pod changes.

func PodMatchesTermsNamespaceAndSelector Uses

❖
func PodMatchesTermsNamespaceAndSelector(pod *v1.Pod, namespaces sets.String, selector labels.Selector) bool

PodMatchesTermsNamespaceAndSelector returns true if the given <pod> matches the namespace and selector defined by <affinityPod>`s <term>.

type Clock Uses

❖
type Clock interface {
    Now() time.Time
}

Clock provides an interface for getting the current time

type RealClock Uses

❖
type RealClock struct{}

RealClock implements a clock using time

func (RealClock) Now Uses

❖
func (RealClock) Now() time.Time

Now returns the current time with time.Now

type Topologies Uses

❖
type Topologies struct {
    DefaultKeys []string
}

Topologies contains topologies information of nodes.

func (*Topologies) NodesHaveSameTopologyKey Uses

❖
func (tps *Topologies) NodesHaveSameTopologyKey(nodeA, nodeB *v1.Node, topologyKey string) bool

NodesHaveSameTopologyKey checks if nodeA and nodeB have same label value with given topologyKey as label key.
