const (
	// ControllerName is the controller name that will be used when reporting events.
	ControllerName = "cluster-status-controller"
)

const WorkStatusControllerName = "work-status-controller"

WorkStatusControllerName is the controller name that will be used when reporting events.

Types

type ClusterStatusController

type ClusterStatusController struct {
	client.Client               // used to operate Cluster resources.
	KubeClient                  clientset.Interface
	EventRecorder               record.EventRecorder
	PredicateFunc               predicate.Predicate
	InformerManager             informermanager.MultiClusterInformerManager
	StopChan                    <-chan struct{}
	ClusterClientSetFunc        func(c *v1alpha1.Cluster, client client.Client) (*util.ClusterClient, error)
	ClusterDynamicClientSetFunc func(c *v1alpha1.Cluster, client client.Client) (*util.DynamicClusterClient, error)

	// ClusterStatusUpdateFrequency is the frequency that controller computes and report cluster status.
	ClusterStatusUpdateFrequency metav1.Duration
	// ClusterLeaseDuration is a duration that candidates for a lease need to wait to force acquire it.
	// This is measure against time of last observed lease RenewTime.
	ClusterLeaseDuration metav1.Duration
	// ClusterLeaseRenewIntervalFraction is a fraction coordinated with ClusterLeaseDuration that
	// how long the current holder of a lease has last updated the lease.
	ClusterLeaseRenewIntervalFraction float64
	// ClusterLeaseControllers store clusters and their corresponding lease controllers.
	ClusterLeaseControllers sync.Map
}

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 informermanager.MultiClusterInformerManager

	StopChan     <-chan struct{}
	WorkerNumber int // WorkerNumber is the number of worker goroutines

	ObjectWatcher        objectwatcher.ObjectWatcher
	PredicateFunc        predicate.Predicate
	ClusterClientSetFunc func(c *v1alpha1.Cluster, client client.Client) (*util.DynamicClusterClient, error)
	// 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.
