Constants

const ControllerName = "managedseed"

ControllerName is the name of this controller.

Variables

var Actuator gardenletdeployer.Interface

Actuator is exposed for testing.

var RandomDurationWithMetaDuration = utils.RandomDurationWithMetaDuration

RandomDurationWithMetaDuration is an alias for `utils.RandomDurationWithMetaDuration`. Exposed for unit tests.

Types

type Reconciler

type Reconciler struct {
	GardenConfig          *rest.Config
	GardenAPIReader       client.Reader
	GardenClient          client.Client
	SeedClient            client.Client
	Config                gardenletconfigv1alpha1.GardenletConfiguration
	Clock                 clock.Clock
	Recorder              record.EventRecorder
	ShootClientMap        clientmap.ClientMap
	GardenNamespaceGarden string
	GardenNamespaceShoot  string
}

Reconciler reconciles the ManagedSeed.

func (*Reconciler) AddToManager

func (r *Reconciler) AddToManager(
	mgr manager.Manager,
	gardenCluster cluster.Cluster,
	seedCluster cluster.Cluster,
) error

AddToManager adds Reconciler to the given manager.

func (*Reconciler) EnqueueWithJitterDelay

func (r *Reconciler) EnqueueWithJitterDelay() handler.EventHandler

EnqueueWithJitterDelay returns handler.Funcs which enqueues the object with a random Jitter duration when the JitterUpdate is enabled in ManagedSeed controller configuration. All other events are normally enqueued.

func (*Reconciler) MapSeedToManagedSeed

func (r *Reconciler) MapSeedToManagedSeed(_ context.Context, obj client.Object) []reconcile.Request

MapSeedToManagedSeed is a handler.MapFunc for mapping a Seed to the owning ManagedSeed.

func (*Reconciler) Reconcile

func (r *Reconciler) Reconcile(ctx context.Context, request reconcile.Request) (reconcile.Result, error)

Reconcile performs the main reconciliation logic.

func (*Reconciler) SeedPredicate

func (r *Reconciler) SeedPredicate() predicate.Predicate

SeedPredicate returns true when the Seed is a ManagedSeed controlled by this gardenlet. ManagedSeeds always have two `name.seed.gardener.cloud/` labels, and since the cache for Seeds is already limited on manager.Manager level to only contain Seeds relevant for this gardenlet, we can make this simple check here.
