ClusterStatusController is to sync status of Cluster.

func (*ClusterStatusController) Reconcile

func (c *ClusterStatusController) Reconcile(ctx context.Context, req controllerruntime.Request) (controllerruntime.Result, error)

Reconcile syncs status of the given member cluster. The Controller will requeue the Request to be processed again if an error is non-nil or Result.Requeue is true, otherwise upon completion it will requeue the reconcile key after the duration.

func (*ClusterStatusController) SetupWithManager

func (c *ClusterStatusController) SetupWithManager(mgr controllerruntime.Manager) error

SetupWithManager creates a controller and register to controller manager.

type WorkStatusController

type WorkStatusController struct {
	client.Client   // used to operate Work resources.
	EventRecorder   record.EventRecorder
	RESTMapper      meta.RESTMapper
	InformerManager genericmanager.MultiClusterInformerManager

	StopChan <-chan struct{}

	// ConcurrentWorkStatusSyncs is the number of Work status that are allowed to sync concurrently.

	RateLimiterOptions        ratelimiterflag.Options
	ResourceInterpreter       resourceinterpreter.ResourceInterpreter
	// contains filtered or unexported fields
}

WorkStatusController is to sync status of Work.

func (*WorkStatusController) Reconcile

func (c *WorkStatusController) Reconcile(ctx context.Context, req controllerruntime.Request) (controllerruntime.Result, error)

Reconcile performs a full reconciliation for the object referred to by the Request. The Controller will requeue the Request to be processed again if an error is non-nil or Result.Requeue is true, otherwise upon completion it will remove the work from the queue.

func (*WorkStatusController) RunWorkQueue

func (c *WorkStatusController) RunWorkQueue()

RunWorkQueue initializes worker and run it, worker will process resource asynchronously.

func (*WorkStatusController) SetupWithManager

func (c *WorkStatusController) SetupWithManager(mgr controllerruntime.Manager) error

SetupWithManager creates a controller and register to controller manager.
