type ResourceBindingStatus 

type ResourceBindingStatus struct {
	// SchedulerObservedGeneration is the generation(.metadata.generation) observed by the scheduler.
	// If SchedulerObservedGeneration is less than the generation in metadata means the scheduler hasn't confirmed
	// the scheduling result or hasn't done the schedule yet.
	// +optional
	SchedulerObservedGeneration int64 `json:"schedulerObservedGeneration,omitempty"`

	// SchedulerObservedAffinityName is the name of affinity term that is
	// the basis of current scheduling.
	// +optional
	SchedulerObservedAffinityName string `json:"schedulerObservingAffinityName,omitempty"`

	// Conditions contain the different condition statuses.
	// +optional
	Conditions []metav1.Condition `json:"conditions,omitempty"`

	// AggregatedStatus represents status list of the resource running in each member cluster.
	// +optional
	AggregatedStatus []AggregatedStatusItem `json:"aggregatedStatus,omitempty"`
}

ResourceBindingStatus represents the overall status of the strategy as well as the referenced resources.

func (*ResourceBindingStatus) DeepCopy 

func (in *ResourceBindingStatus) DeepCopy() *ResourceBindingStatus

DeepCopy is an autogenerated deepcopy function, copying the receiver, creating a new ResourceBindingStatus.

func (*ResourceBindingStatus) DeepCopyInto 

func (in *ResourceBindingStatus) DeepCopyInto(out *ResourceBindingStatus)

DeepCopyInto is an autogenerated deepcopy function, copying the receiver, writing into out. in must be non-nil.

type ResourceHealth added in v1.3.0 

type ResourceHealth string

ResourceHealth represents that the health status of the reference resource. 

const (
	// ResourceHealthy represents that the health status of the current resource
	// that applied on the managed cluster is healthy.
	ResourceHealthy ResourceHealth = "Healthy"
	// ResourceUnhealthy represents that the health status of the current resource
	// that applied on the managed cluster is unhealthy.
	ResourceUnhealthy ResourceHealth = "Unhealthy"
	// ResourceUnknown represents that the health status of the current resource
	// that applied on the managed cluster is unknown.
	ResourceUnknown ResourceHealth = "Unknown"
)

type TargetCluster 

type TargetCluster struct {
	// Name of target cluster.
	Name string `json:"name"`
	// Replicas in target cluster
	// +optional
	Replicas int32 `json:"replicas,omitempty"`
}

TargetCluster represents the identifier of a member cluster.
