Functions

func NewControllerRegistrationFinalizerReconciler

func NewControllerRegistrationFinalizerReconciler(gardenClient client.Client) reconcile.Reconciler

NewControllerRegistrationFinalizerReconciler creates a new reconciler that manages the finalizer on ControllerRegistration objects depending on whether ControllerInstallation objects exist in the system. It basically protects ControllerRegistrations from being deleted, if there are still ControllerInstallations referencing it.

func NewSeedFinalizerReconciler

func NewSeedFinalizerReconciler(gardenClient client.Client) reconcile.Reconciler

NewSeedFinalizerReconciler creates a new reconciler that manages the finalizer on Seed objects depending on whether ControllerInstallation objects exist in the system. It basically protects Seeds from being deleted, if there are still ControllerInstallations referencing it, to make sure we are able to cleanup ControllerInstallation objects of terminating Seeds.

func NewSeedReconciler

func NewSeedReconciler(gardenClient kubernetes.Interface) reconcile.Reconciler

NewSeedReconciler creates a new reconciler which determines which ControllerRegistrations are required for a given Seed by checking all objects in the garden cluster, that need to be considered for that Seed (e.g. because they reference the Seed). It then deploys wanted and deletes unneeded ControllerInstallations accordingly. Seeds get enqueued by updates to relevant (referencing) objects, e.g. Shoots, BackupBuckets, etc.. This is the main reconciler of this controller, that does the actual work.

Types

type Controller

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

Controller implements the logic behind ControllerRegistrations. It creates and deletes ControllerInstallations for ControllerRegistrations for the Seeds where they are needed or not.

func NewController

func NewController(ctx context.Context, log logr.Logger, clientMap clientmap.ClientMap) (*Controller, error)

NewController instantiates a new ControllerRegistration controller.

func (*Controller) Run

func (c *Controller) Run(ctx context.Context, workers int)

Run runs the Controller until the given stop channel can be read from.
