Functions

func Add

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

Add creates a new Infrastructure Controller and adds it to the Manager. and Start it when the Manager is Started.

func ClusterToInfrastructureMapper

func ClusterToInfrastructureMapper(mgr manager.Manager, predicates []predicate.Predicate) mapper.Mapper

ClusterToInfrastructureMapper returns a mapper that returns requests for Infrastructures whose referenced clusters have been modified.

func DefaultPredicates

func DefaultPredicates(ctx context.Context, mgr manager.Manager, ignoreOperationAnnotation bool) []predicate.Predicate

DefaultPredicates returns the default predicates for an infrastructure reconciler.

func NewReconciler

func NewReconciler(mgr manager.Manager, actuator Actuator, configValidator ConfigValidator, knownCodes map[gardencorev1beta1.ErrorCode]func(string) bool) reconcile.Reconciler

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

Types

type Actuator

type Actuator interface {
	// Reconcile the Infrastructure config.
	Reconcile(context.Context, logr.Logger, *extensionsv1alpha1.Infrastructure, *extensionscontroller.Cluster) error
	// Delete the Infrastructure config.
	Delete(context.Context, logr.Logger, *extensionsv1alpha1.Infrastructure, *extensionscontroller.Cluster) error
	// ForceDelete forcefully deletes the Infrastructure config.
	ForceDelete(context.Context, logr.Logger, *extensionsv1alpha1.Infrastructure, *extensionscontroller.Cluster) error
	// Restore takes the state of the Infrastructure resource and applies it to the terraform pod's output state
	Restore(context.Context, logr.Logger, *extensionsv1alpha1.Infrastructure, *extensionscontroller.Cluster) error
	// Migrate deletes the terraform k8s resources without deleting the corresponding resources in the IaaS provider
	Migrate(context.Context, logr.Logger, *extensionsv1alpha1.Infrastructure, *extensionscontroller.Cluster) error
}

Actuator acts upon Infrastructure resources.

type AddArgs

type AddArgs struct {
	// Actuator is an Infrastructure actuator.
	Actuator Actuator
	// ConfigValidator is an Infrastructure config validator.
	ConfigValidator ConfigValidator
	// 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.
	// If unset, GenerationChangedPredicate will be used.
	Predicates []predicate.Predicate
	// Type is the type of the resource considered for reconciliation.
	Type string
	// WatchBuilder defines additional watches on controllers that should be set up.
	WatchBuilder extensionscontroller.WatchBuilder
	// 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
	// ExtensionClass defines the extension class this extension is responsible for.
	ExtensionClass extensionsv1alpha1.ExtensionClass
	// KnownCodes is a map of known error codes and their respective error check functions.
	KnownCodes map[gardencorev1beta1.ErrorCode]func(string) bool
}

AddArgs are arguments for adding an Infrastructure controller to a manager.

type ConfigValidator

type ConfigValidator interface {
	// Validate validates the provider config of the given infrastructure resource with the cloud provider.
	// If the returned error list is non-empty, the reconciliation will fail with an error.
	// This error will have the error code ERR_CONFIGURATION_PROBLEM, unless there is at least one error in the list
	// that has its ErrorType field set to field.ErrorTypeInternal.
	Validate(ctx context.Context, infra *extensionsv1alpha1.Infrastructure) field.ErrorList
}

ConfigValidator validates the provider config of infrastructures resource with the cloud provider.
