Functions

func GetContainerPorts

func GetContainerPorts(pods ...*v1.Pod) []*v1.ContainerPort

GetContainerPorts returns the used host ports of Pods: if 'port' was used, a 'port:true' pair will be in the result; but it does not resolve port conflict.

func GetEarliestPodStartTime

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 GetPodFullName

func GetPodFullName(pod *v1.Pod) string

GetPodFullName returns a name that uniquely identifies a pod.

func GetPodStartTime

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 MoreImportantPod

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.

Types

type Clock

type Clock interface {
	Now() time.Time
}

Clock provides an interface for getting the current time

type ErrorChannel

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

ErrorChannel supports non-blocking send and receive operation to capture error. A maximum of one error is kept in the channel and the rest of the errors sent are ignored, unless the existing error is received and the channel becomes empty again.

func NewErrorChannel

func NewErrorChannel() *ErrorChannel

NewErrorChannel returns a new ErrorChannel.

func (*ErrorChannel) ReceiveError

func (e *ErrorChannel) ReceiveError() error

ReceiveError receives an error from channel without blocking on the receiver.

func (*ErrorChannel) SendError

func (e *ErrorChannel) SendError(err error)

SendError sends an error without blocking the sender.

func (*ErrorChannel) SendErrorWithCancel

func (e *ErrorChannel) SendErrorWithCancel(err error, cancel context.CancelFunc)

SendErrorWithCancel sends an error without blocking the sender and calls cancel function.

type RealClock

type RealClock struct{}

RealClock implements a clock using time

func (RealClock) Now

func (RealClock) Now() time.Time

Now returns the current time with time.Now
