Package handler defines EventHandlers that enqueue reconcile.Requests in response to Create, Update, Deletion Events
|
||
|
|
observed from Watching Kubernetes APIs. Users should provide a source.Source and handler.EventHandler to
|
||
|
|
Controller.Watch in order to generate and enqueue reconcile.Request work items.
|
||
|
|
|
||
|
|
Generally, following premade event handlers should be sufficient for most use cases:
|
||
|
|
|
||
|
|
EventHandlers
|
||
|
|
|
||
|
|
EnqueueRequestForObject - Enqueues a reconcile.Request containing the Name and Namespace of the object in the Event. This will
|
||
|
|
cause the object that was the source of the Event (e.g. the created / deleted / updated object) to be
|
||
|
|
reconciled.
|
||
|
|
|
||
|
|
EnqueueRequestForOwner - Enqueues a reconcile.Request containing the Name and Namespace of the Owner of the object in the Event.
|
||
|
|
This will cause owner of the object that was the source of the Event (e.g. the owner object that created the object)
|
||
|
|
to be reconciled.
|
||
|
|
|
||
|
|
EnqueueRequestsFromMapFunc - Enqueues reconcile.Requests resulting from a user provided transformation function run against the
|
||
|
|
object in the Event. This will cause an arbitrary collection of objects (defined from a transformation of the
|
||
|
|
source object) to be reconciled.
