Functions

func IndexControllerOf

func IndexControllerOf(mgr kube_ctrl.Manager, ownerGVK kube_schema.GroupVersionKind, objType kube_client.Object) error

IndexControllerOf adds an index to objects of this GVK for use with ManageControlledObject.

func ManageControlledObject

func ManageControlledObject(
	ctx context.Context, client kube_client.Client, owner kube_meta.Object, objectList kube_client.ObjectList, mutate func(kube_client.Object) (kube_client.Object, error),
) (kube_client.Object, error)

ManageControlledObject is used to handle the lifecycle of and mutate a single object controlled by owner. This object type must be indexed by calling IndexControllerOf. If a controlled object exists, it's passed to mutate. Otherwise mutate receives a nil object. mutate should return a nil Object if the owned object should be deleted or not created.
