Functions

func AddToManager

func AddToManager(ctx context.Context, mgr manager.Manager) error

AddToManager adds a controller with the default Options.

func AddToManagerWithOptions

func AddToManagerWithOptions(ctx context.Context, mgr manager.Manager, opts AddOptions) error

AddToManagerWithOptions adds a controller with the given Options to the given manager. The opts.Reconciler is being set with a newly instantiated actuator.

func ComputeInstanceMetadata

func ComputeInstanceMetadata(workerConfig *awsapi.WorkerConfig, cluster *controller.Cluster) (map[string]interface{}, error)

ComputeInstanceMetadata calculates the InstanceMetadata options for a particular worker pool.

func NewActuator

func NewActuator(mgr manager.Manager, gardenCluster cluster.Cluster) worker.Actuator

NewActuator creates a new Actuator that updates the status of the handled WorkerPoolConfigs.

func NewWorkerDelegate

func NewWorkerDelegate(
	client client.Client,
	decoder runtime.Decoder,
	scheme *runtime.Scheme,

	seedChartApplier gardener.ChartApplier,
	serverVersion string,

	worker *extensionsv1alpha1.Worker,
	cluster *extensionscontroller.Cluster,
) (genericactuator.WorkerDelegate, error)

NewWorkerDelegate creates a new context for a worker reconciliation.

Types

type AddOptions

type AddOptions struct {
	// GardenCluster is the garden cluster object.
	GardenCluster cluster.Cluster
	// Controller are the controller.Options.
	Controller controller.Options
	// IgnoreOperationAnnotation specifies whether to ignore the operation annotation or not.
	IgnoreOperationAnnotation bool
	// ExtensionClass defines the extension class this extension is responsible for.
	ExtensionClass extensionsv1alpha1.ExtensionClass
}

AddOptions are options to apply when adding the AWS worker controller to the manager.

type WorkerDelegate

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