Overview ¶
Package tracker defines a utility to enable Reconcilers to trigger reconciliations when objects that are cross-referenced change, so that the level-based reconciliation can react to the change. The prototypical cross-reference in Kubernetes is corev1.ObjectReference.

Types ¶
type Interface ¶
type Interface interface {
// Track tells us that "obj" is tracking changes to the
// referenced object.
Track(ref corev1.ObjectReference, obj interface{}) error
// OnChanged is a callback to register with the InformerFactory
// so that we are notified for appropriate object changes.
OnChanged(obj interface{})
}
Interface defines the interface through which an object can register that it is tracking another object by reference.
func New ¶
func New(callback func(types.NamespacedName), lease time.Duration) Interface
New returns an implementation of Interface that lets a Reconciler register a particular resource as watching an ObjectReference for a particular lease duration. This watch must be refreshed periodically (e.g. by a controller resync) or it will expire.
When OnChanged is called by the informer for a particular GroupVersionKind, the provided callback is called with the "key" of each object actively watching the changed object.
