Types

type ControlInterface

type ControlInterface interface {
	// ReconcileSeed implements the control logic for Seed creation, update, and deletion.
	// If an implementation returns a non-nil error, the invocation will be retried using a rate-limited strategy.
	// Implementors should sink any errors that they do not wish to trigger a retry, and they may feel free to
	// exit exceptionally at any point provided they wish the update to be re-run at a later point in time.
	ReconcileSeed(seed *gardencorev1beta1.Seed, key string) error
}

ControlInterface implements the control logic for updating Seeds. It is implemented as an interface to allow for extensions that provide different semantics. Currently, there is only one implementation.

func NewDefaultControl

func NewDefaultControl(
	clientMap clientmap.ClientMap,
	k8sGardenCoreInformers gardencoreinformers.SharedInformerFactory,
	imageVector imagevector.ImageVector,
	componentImageVectors imagevector.ComponentImageVectors,
	identity *gardencorev1beta1.Gardener,
	recorder record.EventRecorder,
	config *config.GardenletConfiguration,
	secretLister kubecorev1listers.SecretLister,
	seedLister gardencorelisters.SeedLister,
	shootLister gardencorelisters.ShootLister,
) ControlInterface

NewDefaultControl returns a new instance of the default implementation ControlInterface that implements the documented semantics for Seeds. You should use an instance returned from NewDefaultControl() for any scenario other than testing.

type Controller

type Controller struct {
	// contains filtered or unexported fields
}

Controller controls Seeds.

func NewSeedController

func NewSeedController(
	clientMap clientmap.ClientMap,
	gardenCoreInformerFactory gardencoreinformers.SharedInformerFactory,
	kubeInformerFactory kubeinformers.SharedInformerFactory,
	healthManager healthz.Manager,
	imageVector imagevector.ImageVector,
	componentImageVectors imagevector.ComponentImageVectors,
	identity *gardencorev1beta1.Gardener,
	config *config.GardenletConfiguration,
	recorder record.EventRecorder,
) *Controller

NewSeedController takes a Kubernetes client for the Garden clusters <k8sGardenClient>, a struct holding information about the acting Gardener, a <seedInformer>, and a <recorder> for event recording. It creates a new Gardener controller.

func (*Controller) CollectMetrics

func (c *Controller) CollectMetrics(ch chan<- prometheus.Metric)

CollectMetrics implements gardenmetrics.ControllerMetricsCollector interface

func (*Controller) Run

func (c *Controller) Run(ctx context.Context, workers int)

Run runs the Controller until the given stop channel can be read from.

func (*Controller) RunningWorkers

func (c *Controller) RunningWorkers() int

RunningWorkers returns the number of running workers.

type ExtensionCheckControlInterface

type ExtensionCheckControlInterface interface {
	// ReconcileExtensionCheckFor implements the control logic for Seed extension checks.
	// If an implementation returns a non-nil error, the invocation will be retried using a rate-limited strategy.
	// Implementors should sink any errors that they do not wish to trigger a retry, and they may feel free to
	// exit exceptionally at any point provided they wish the update to be re-run at a later point in time.
	ReconcileExtensionCheckFor(seed *gardencorev1beta1.Seed) error
}

ExtensionCheckControlInterface implements the control logic for updating Seeds. It is implemented as an interface to allow for extensions that provide different semantics. Currently, there is only one implementation.

func NewDefaultExtensionCheckControl

func NewDefaultExtensionCheckControl(
	clientMap clientmap.ClientMap,
	controllerInstallationLister gardencorelisters.ControllerInstallationLister,
	nowFunc func() metav1.Time,
) ExtensionCheckControlInterface

NewDefaultExtensionCheckControl returns a new instance of the default implementation ExtensionCheckControlInterface that implements the documented semantics for Seeds. You should use an instance returned from NewDefaultExtensionCheckControl() for any scenario other than testing.
