Types

type FailureError

type FailureError struct {
	PodName string
}

FailureError is returned when the FailTiDBSchedulerLabelKey is seen

func (FailureError) Error

func (ferr FailureError) Error() string

type Scheduler

type Scheduler interface {
	// Filter based on extender-implemented predicate functions. The filtered list is
	// expected to be a subset of the supplied list.
	Filter(*schedulerapi.ExtenderArgs) (*schedulerapi.ExtenderFilterResult, error)

	// Preempt implements scheduler extender preempt verb.
	Preempt(args *schedulerapi.ExtenderPreemptionArgs) (*schedulerapi.ExtenderPreemptionResult, error)

	// Prioritize based on extender-implemented priority functions. The returned scores & weight
	// are used to compute the weighted score for an extender. The weighted scores are added to
	// the scores computed  by kubernetes scheduler. The total scores are used to do the host selection.
	Priority(*schedulerapi.ExtenderArgs) (schedulerapi.HostPriorityList, error)
}

Scheduler is an interface for external processes to influence scheduling decisions made by kubernetes. This is typically needed for resources not directly managed by kubernetes.
