Documentation

Overview

Package event contains the definitions for the Event types produced by source.Sources and transformed into reconcile.Requests by handler.EventHandler.

You should rarely need to work with these directly -- instead, use Controller.Watch with source.Sources and handler.EventHandlers.

Events generally contain both a full runtime.Object that caused the event, as well as a direct handle to that object's metadata. This saves a lot of typecasting in code that works with Events.

Types

type CreateEvent

type CreateEvent struct {
	// Object is the object from the event
	Object client.Object
}

CreateEvent is an event where a Kubernetes object was created. CreateEvent should be generated by a source.Source and transformed into a reconcile.Request by an handler.EventHandler.

type DeleteEvent

type DeleteEvent struct {
	// Object is the object from the event
	Object client.Object

	// DeleteStateUnknown is true if the Delete event was missed but we identified the object
	// as having been deleted.
	DeleteStateUnknown bool
}

DeleteEvent is an event where a Kubernetes object was deleted. DeleteEvent should be generated by a source.Source and transformed into a reconcile.Request by an handler.EventHandler.

type GenericEvent

type GenericEvent struct {
	// Object is the object from the event
	Object client.Object
}

GenericEvent is an event where the operation type is unknown (e.g. polling or event originating outside the cluster). GenericEvent should be generated by a source.Source and transformed into a reconcile.Request by an handler.EventHandler.

type UpdateEvent

type UpdateEvent struct {
	// ObjectOld is the object from the event
	ObjectOld client.Object

	// ObjectNew is the object from the event
	ObjectNew client.Object
}

UpdateEvent is an event where a Kubernetes object was updated. UpdateEvent should be generated by a source.Source and transformed into a reconcile.Request by an handler.EventHandler.
