Types

type ScheduleAlgorithm

type ScheduleAlgorithm interface {
	Schedule(context.Context, *policyv1alpha1.Placement, *workv1alpha2.ResourceBindingSpec, *ScheduleAlgorithmOption) (scheduleResult ScheduleResult, err error)
}

ScheduleAlgorithm is the interface that should be implemented to schedule a resource to the target clusters.

func NewGenericScheduler

func NewGenericScheduler(
	schedCache cache.Cache,
	registry runtime.Registry,
) (ScheduleAlgorithm, error)

NewGenericScheduler creates a genericScheduler object.

type ScheduleAlgorithmOption

type ScheduleAlgorithmOption struct {
	EnableEmptyWorkloadPropagation bool
}

ScheduleAlgorithmOption represents the option for ScheduleAlgorithm.

type ScheduleResult

type ScheduleResult struct {
	SuggestedClusters []workv1alpha2.TargetCluster
}

ScheduleResult includes the clusters selected.

type TargetClustersList

type TargetClustersList []workv1alpha2.TargetCluster

TargetClustersList is a slice of TargetCluster that implements sort.Interface to sort by Value.

func (TargetClustersList) Len

func (a TargetClustersList) Len() int

func (TargetClustersList) Less

func (a TargetClustersList) Less(i, j int) bool

func (TargetClustersList) Swap

func (a TargetClustersList) Swap(i, j int)
