Functions

func Add

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

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

func DefaultPredicates

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

DefaultPredicates returns the default predicates for an operatingsystemconfig reconciler.

func FilesToDiskScript

func FilesToDiskScript(ctx context.Context, reader client.Reader, namespace string, files []extensionsv1alpha1.File) (string, error)

FilesToDiskScript is a utility function which generates a bash script for writing the provided files to the disk.

func NewReconciler

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

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

func SecretObjectMetaForConfig

func SecretObjectMetaForConfig(config *extensionsv1alpha1.OperatingSystemConfig) metav1.ObjectMeta

SecretObjectMetaForConfig returns the object meta structure that can be used inside the secret that shall contain the generated OSC output.

func UnitsToDiskScript

func UnitsToDiskScript(units []extensionsv1alpha1.Unit) string

UnitsToDiskScript is a utility function which generates a bash script for writing the provided units and their drop-ins to the disk.

Types

type Actuator

type Actuator interface {
	// Reconcile the operating system config.
	Reconcile(context.Context, logr.Logger, *extensionsv1alpha1.OperatingSystemConfig) ([]byte, []extensionsv1alpha1.Unit, []extensionsv1alpha1.File, error)
	// Delete the operating system config.
	Delete(context.Context, logr.Logger, *extensionsv1alpha1.OperatingSystemConfig) error
	// ForceDelete forcefully deletes the operating system config.
	ForceDelete(context.Context, logr.Logger, *extensionsv1alpha1.OperatingSystemConfig) error
	// Restore the operating system config.
	Restore(context.Context, logr.Logger, *extensionsv1alpha1.OperatingSystemConfig) ([]byte, []extensionsv1alpha1.Unit, []extensionsv1alpha1.File, error)
	// Migrate the operating system config.
	Migrate(context.Context, logr.Logger, *extensionsv1alpha1.OperatingSystemConfig) error
}

Actuator acts upon OperatingSystemConfig resources.

type AddArgs

type AddArgs struct {
	// Actuator is an operatingsystemconfig actuator.
	Actuator Actuator
	// 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
	// Types are the similar types which can be combined with a logic or,
	// of the resource considered for reconciliation.
	Types []string
}

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