    func NewActuator

    func NewActuator(logger logr.Logger, delegateFactory DelegateFactory, mcmName string, mcmSeedChart, mcmShootChart chart.Interface, imageVector imagevector.ImageVector, chartRendererFactory extensionscontroller.ChartRendererFactory) worker.Actuator

      NewActuator creates a new Actuator that reconciles Worker resources of Gardener's `` API group. It provides a default implementation that allows easier integration of providers.

      func ReadMachineConfiguration

      func ReadMachineConfiguration(pool extensionsv1alpha1.WorkerPool) *machinev1alpha1.MachineConfiguration

        ReadMachineConfiguration reads the configuration from worker-pool and returns the corresponding configuration of machine-deployment.


        type DelegateFactory

        type DelegateFactory interface {
        	// WorkerDelegate returns a worker delegate interface that is used for the Worker reconciliation
        	// based on this generic actuator.
        	WorkerDelegate(context.Context, *extensionsv1alpha1.Worker, *extensionscontroller.Cluster) (WorkerDelegate, error)

          DelegateFactory acts upon Worker resources.

          type ReplicaCount

          type ReplicaCount func() (int32, error)

            ReplicaCount determines the number of replicas.

            type WorkerCredentialsDelegate

            type WorkerCredentialsDelegate interface {
            	// GetMachineControllerManagerCloudCredentials should return the IaaS credentials
            	// with the secret keys used by the machine-controller-manager.
            	GetMachineControllerManagerCloudCredentials(context.Context) (map[string][]byte, error)

              WorkerCredentialsDelegate is an interface that can optionally be implemented to be used during the Worker reconciliation to keep all machine class secrets up to date. DEPRECATED: extensions should instead provide credentials only (!) via the machine class field .spec.credentialsSecretRef referencing the Worker's secret reference (spec.SecretRef). This way all machine classes reference the same secret - there is no need anymore to update all machine class secrets. please see [here]( for more details

              type WorkerDelegate

              type WorkerDelegate interface {

              	// GetMachineControllerManagerShootChartValues should return the values to render the chart containing resources
              	// that are required by the machine-controller-manager inside the shoot cluster itself.

              	// UpdateMachineImagesStatus will store a list of machine images used by the
              	// machines associated with this Worker resource in its provider status.
              	// The controller can look up its provider-specific machine image information
              	// in case the required version has been removed from the `CloudProfile`.

              	// CleanupMachineDependencies is a hook to cleanup external machine dependencies.
              	CleanupMachineDependencies(context.Context) error

                WorkerDelegate is used for the Worker reconciliation.
