Functions

func Add

func Add(mgr manager.Manager, args AddArgs) error

Add adds an ContainerRuntime controller to the given manager using the given AddArgs.

func ClusterToContainerResourceMapper

func ClusterToContainerResourceMapper(predicates ...predicate.Predicate) extensionshandler.Mapper

ClusterToContainerResourceMapper returns a mapper that returns requests for Container resource whose referenced clusters have been modified.

func DefaultPredicates

func DefaultPredicates(ignoreOperationAnnotation bool) []predicate.Predicate

DefaultPredicates returns the default predicates for an containerruntime reconciler.

func NewReconciler

func NewReconciler(mgr manager.Manager, actuator Actuator) reconcile.Reconciler

NewReconciler creates a new reconcile.Reconciler that reconciles ContainerRuntime resources of Gardener's `extensions.gardener.cloud` API group.

Types

type Actuator

type Actuator interface {
	// Reconcile the ContainerRuntime resource.
	Reconcile(context.Context, *extensionsv1alpha1.ContainerRuntime, *extensioncontroller.Cluster) error
	// Delete the ContainerRuntime resource.
	Delete(context.Context, *extensionsv1alpha1.ContainerRuntime, *extensioncontroller.Cluster) error
	// Restore the ContainerRuntime resource.
	Restore(context.Context, *extensionsv1alpha1.ContainerRuntime, *extensioncontroller.Cluster) error
	// Migrate the ContainerRuntime resource.
	Migrate(context.Context, *extensionsv1alpha1.ContainerRuntime, *extensioncontroller.Cluster) error
}

Actuator acts upon ContainerRuntime resources.

type AddArgs

type AddArgs struct {
	// Actuator is an ContainerRuntime resource actuator.
	Actuator Actuator
	// FinalizerSuffix is the suffix for the finalizer name.
	FinalizerSuffix string
	// ControllerOptions are the controller options used for creating a controller.
	// The options.Reconciler is always overridden with a reconciler created from the
	// given actuator.
	ControllerOptions controller.Options
	// Predicates are the predicates to use.
	Predicates []predicate.Predicate
	// Resync determines the requeue interval.
	Resync time.Duration
	// Type is the type of the resource considered for reconciliation.
	Type string
	// IgnoreOperationAnnotation specifies whether to ignore the operation annotation or not.
	// If the annotation is not ignored, the extension controller will only reconcile
	// with a present operation annotation typically set during a reconcile (e.g in the maintenance time) by the Gardenlet
	IgnoreOperationAnnotation bool
}

AddArgs are arguments for adding an ContainerRuntime resources controller to a manager.
