Functions

func IsShootManagedByThisGardenlet

func IsShootManagedByThisGardenlet(shoot *gardencorev1beta1.Shoot, gc *config.GardenletConfiguration) bool

IsShootManagedByThisGardenlet checks if the given shoot is managed by this gardenlet by comparing it with the seed name from the GardenletConfiguration.

func NewCareReconciler

func NewCareReconciler(
	gardenClient client.Client,
	seedClientSet kubernetes.Interface,
	shootClientMap clientmap.ClientMap,
	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.

func NewMigrationReconciler

func NewMigrationReconciler(gardenClient client.Client, config *config.GardenletConfiguration) reconcile.Reconciler

NewMigrationReconciler returns an implementation of reconcile.Reconciler that forces the shoot's restoration to this seed during control plane migration if the preparation for migration in the source seed is not finished after a certain grace period and is considered unlikely to succeed ("bad case" scenario).

func NewShootReconciler

func NewShootReconciler(
	gardenClient client.Client,
	seedClientSet kubernetes.Interface,
	shootClientMap clientmap.ClientMap,
	recorder record.EventRecorder,
	imageVector imagevector.ImageVector,
	identity *gardencorev1beta1.Gardener,
	gardenClusterIdentity string,
	config *config.GardenletConfiguration,
) reconcile.Reconciler

NewShootReconciler returns a reconciler that implements the main shoot reconciliation logic, i.e creation, hibernation, migration and deletion.

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(
	ctx context.Context,
	log logr.Logger,
	gardenCluster cluster.Cluster,
	seedClientSet kubernetes.Interface,
	shootClientMap clientmap.ClientMap,
	config *config.GardenletConfiguration,
	identity *gardencorev1beta1.Gardener,
	gardenClusterIdentity string,
	imageVector imagevector.ImageVector,
) (
	*Controller,
	error,
)

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) Run

func (c *Controller) Run(ctx context.Context, shootWorkers, shootCareWorkers, shootMigrationWorkers int)

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

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.

	secrets map[string]*corev1.Secret,
	imageVector imagevector.ImageVector,
	shoot *gardencorev1beta1.Shoot,
) (
	*operation.Operation,
	error,
)
