Functions

func NewCareReconciler

func NewCareReconciler(clientMap clientmap.ClientMap, k8sGardenCoreInformers gardencoreinformers.Interface, imageVector imagevector.ImageVector, identity *gardencorev1beta1.Gardener, gardenClusterIdentity string, config *config.GardenletConfiguration) reconcile.Reconciler

NewCareReconciler returns an implementation of reconcile.Reconciler which is dedicated to execute care operations on shoots, e.g., health checks or garbage collection.

Types

type ConstraintCheck

type ConstraintCheck interface {
	Check(ctx context.Context, constraints []gardencorev1beta1.Condition) []gardencorev1beta1.Condition
}

ConstraintCheck is an interface used to perform constraint checks.

type Controller

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

Controller controls Shoots.

func NewShootController

func NewShootController(clientMap clientmap.ClientMap, k8sGardenCoreInformers gardencoreinformers.SharedInformerFactory, config *config.GardenletConfiguration, identity *gardencorev1beta1.Gardener,
	gardenClusterIdentity string, imageVector imagevector.ImageVector, recorder record.EventRecorder) *Controller

NewShootController takes a Kubernetes client for the Garden clusters <k8sGardenClient>, a struct holding information about the acting Gardener, a <shootInformer>, 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, shootWorkers, shootCareWorkers 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 ControllerInstallationControlInterface

type ControllerInstallationControlInterface interface {
	Reconcile(controllerInstallationObj *gardencorev1beta1.ControllerInstallation) ([]*gardencorev1beta1.Shoot, error)
}

ControllerInstallationControlInterface implements the control logic for requeuing Shoots after extensions have been updated. It is implemented as an interface to allow for extensions that provide different semantics. Currently, there is only one implementation.

func NewDefaultControllerInstallationControl

func NewDefaultControllerInstallationControl(clientMap clientmap.ClientMap, k8sGardenCoreInformers gardencoreinformers.Interface, recorder record.EventRecorder) ControllerInstallationControlInterface

NewDefaultControllerInstallationControl returns a new instance of the default implementation ControllerInstallationControlInterface that implements the documented semantics for maintaining Shoots. You should use an instance returned from NewDefaultControllerInstallationControl() for any scenario other than testing.

type GarbageCollector

type GarbageCollector interface {
	Collect(ctx context.Context)
}

GarbageCollector is an interface used to perform garbage collection.

type HealthCheck

type HealthCheck interface {
	Check(ctx context.Context, thresholdMapping map[gardencorev1beta1.ConditionType]time.Duration, threshold *metav1.Duration, conditions []gardencorev1beta1.Condition) []gardencorev1beta1.Condition
}

HealthCheck is an interface used to perform health checks.

type NewConstraintCheckFunc

type NewConstraintCheckFunc func(op *operation.Operation, init care.ShootClientInit) ConstraintCheck

NewConstraintCheckFunc is a function used to create a new instance for performing constraint checks.

type NewGarbageCollectorFunc

type NewGarbageCollectorFunc func(op *operation.Operation, init care.ShootClientInit) GarbageCollector

NewGarbageCollectorFunc is a function used to create a new instance to perform garbage collection.

type NewHealthCheckFunc

type NewHealthCheckFunc func(op *operation.Operation, init care.ShootClientInit) HealthCheck

NewHealthCheckFunc is a function used to create a new instance for performing health checks.

type NewOperationFunc

type NewOperationFunc func(
	ctx context.Context,
	gardenClient kubernetes.Interface,
	seedClient kubernetes.Interface,
	config *config.GardenletConfiguration,
	gardenerInfo *gardencorev1beta1.Gardener,
	gardenClusterIdentity string,
	secrets map[string]*corev1.Secret,
	imageVector imagevector.ImageVector,
	k8sGardenCoreInformers v1beta1.Interface,
	clientMap clientmap.ClientMap,
	shoot *gardencorev1beta1.Shoot,
	logger *logrus.Entry,
) (
	*operation.Operation,
	error,
)

NewOperationFunc is a function used to create a new `operation.Operation` instance.

type SeedRegistrationControlInterface

type SeedRegistrationControlInterface interface {
	Reconcile(ctx context.Context, shoot *gardencorev1beta1.Shoot, shootedSeed *gardencorev1beta1helper.ShootedSeed) (reconcile.Result, error)
}

SeedRegistrationControlInterface implements the control logic for reconciling shooted seeds. It is implemented as an interface to allow for extensions that provide different semantics. Currently, there is only one implementation.

func NewDefaultSeedRegistrationControl

func NewDefaultSeedRegistrationControl(clientMap clientmap.ClientMap, recorder record.EventRecorder, logger *logrus.Logger) SeedRegistrationControlInterface

NewDefaultSeedRegistrationControl returns a new instance of the default implementation of the SeedRegistrationControlInterface that implements the documented semantics for registering shooted seeds. You should use an instance returned from NewDefaultSeedRegistrationControl() for any scenario other than testing.
