var RandomDurationWithMetaDuration = utils.RandomDurationWithMetaDuration

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

Types

type Actuator

type Actuator interface {
	// Reconcile reconciles ManagedSeed creation or update.
	Reconcile(context.Context, logr.Logger, *seedmanagementv1alpha1.ManagedSeed) (*seedmanagementv1alpha1.ManagedSeedStatus, bool, error)
	// Delete reconciles ManagedSeed deletion.
	Delete(context.Context, logr.Logger, *seedmanagementv1alpha1.ManagedSeed) (*seedmanagementv1alpha1.ManagedSeedStatus, bool, bool, error)
}

Actuator acts upon ManagedSeed resources.

type Reconciler

type Reconciler struct {
	GardenClient          client.Client
	Actuator              Actuator
	Config                config.GardenletConfiguration
	Clock                 clock.Clock
	ShootClientMap        clientmap.ClientMap
	ImageVector           imagevector.ImageVector
	ChartsPath            string
	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) ManagedSeedPredicate

func (r *Reconciler) ManagedSeedPredicate(seedName string) predicate.Predicate

ManagedSeedPredicate returns the predicate for ManagedSeed events.

func (*Reconciler) MapSeedToManagedSeed

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

MapSeedToManagedSeed is a mapper.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) SeedOfManagedSeedPredicate

func (r *Reconciler) SeedOfManagedSeedPredicate(seedName string) predicate.Predicate

SeedOfManagedSeedPredicate returns the predicate for Seed events.

type ValuesHelper

type ValuesHelper interface {
	// MergeGardenletDeployment merges the given GardenletDeployment with the values from the parent gardenlet.
	MergeGardenletDeployment(*seedmanagementv1alpha1.GardenletDeployment, *gardencorev1beta1.Shoot) (*seedmanagementv1alpha1.GardenletDeployment, error)
	// MergeGardenletConfiguration merges the given GardenletConfiguration with the parent GardenletConfiguration.
	MergeGardenletConfiguration(config *gardenletv1alpha1.GardenletConfiguration) (*gardenletv1alpha1.GardenletConfiguration, error)
	// GetGardenletChartValues computes the values to be used when applying the gardenlet chart.
	GetGardenletChartValues(*seedmanagementv1alpha1.GardenletDeployment, *gardenletv1alpha1.GardenletConfiguration, string) (map[string]interface{}, error)
}

ValuesHelper provides methods for merging GardenletDeployment and GardenletConfiguration with parent, as well as computing the values to be used when applying the gardenlet chart.

func NewValuesHelper

func NewValuesHelper(config *config.GardenletConfiguration, imageVector imagevector.ImageVector) ValuesHelper

NewValuesHelper creates a new ValuesHelper with the given parent GardenletConfiguration and image vector.
