Types ¶
type EventBroadcaster ¶
type EventBroadcaster interface {
// StartRecordingToSink starts sending events received from the specified eventBroadcaster.
StartRecordingToSink(stopCh <-chan struct{})
// NewRecorder returns an EventRecorder that can be used to send events to this EventBroadcaster
// with the event source set to the given event source.
NewRecorder(scheme *runtime.Scheme, reportingController string) EventRecorder
// StartEventWatcher enables you to watch for emitted events without usage
// of StartRecordingToSink. This lets you also process events in a custom way (e.g. in tests).
// NOTE: events received on your eventHandler should be copied before being used.
// TODO: figure out if this can be removed.
StartEventWatcher(eventHandler func(event runtime.Object)) func()
// Shutdown shuts down the broadcaster
Shutdown()
}
EventBroadcaster knows how to receive events and send them to any EventSink, watcher, or log.
func NewBroadcaster ¶
func NewBroadcaster(sink EventSink) EventBroadcaster
NewBroadcaster Creates a new event broadcaster.
type EventRecorder ¶
type EventRecorder interface {
// Eventf constructs an event from the given information and puts it in the queue for sending.
// 'regarding' is the object this event is about. Event will make a reference-- or you may also
// pass a reference to the object directly.
// 'related' is the secondary object for more complex actions. E.g. when regarding object triggers
// a creation or deletion of related object.
// 'type' of this event, and can be one of Normal, Warning. New types could be added in future
// 'reason' is the reason this event is generated. 'reason' should be short and unique; it
// should be in UpperCamelCase format (starting with a capital letter). "reason" will be used
// to automate handling of events, so imagine people writing switch statements to handle them.
// You want to make that easy.
// 'action' explains what happened with regarding/what action did the ReportingController
// (ReportingController is a type of a Controller reporting an Event, e.g. k8s.io/node-controller, k8s.io/kubelet.)
// take in regarding's name; it should be in UpperCamelCase format (starting with a capital letter).
// 'note' is intended to be human readable.
Eventf(regarding runtime.Object, related runtime.Object, eventtype, reason, action, note string, args ...interface{})
}
EventRecorder knows how to record events on behalf of an EventSource.
type EventSink ¶
type EventSink interface {
Create(event *v1beta1.Event) (*v1beta1.Event, error)
Update(event *v1beta1.Event) (*v1beta1.Event, error)
Patch(oldEvent *v1beta1.Event, data []byte) (*v1beta1.Event, error)
}
EventSink knows how to store events (client-go implements it.) EventSink must respect the namespace that will be embedded in 'event'. It is assumed that EventSink will return the same sorts of errors as client-go's REST client.
type EventSinkImpl ¶
type EventSinkImpl struct {
Interface typedv1beta1.EventInterface
}
EventSinkImpl wraps EventInterface to implement EventSink. TODO: this makes it easier for testing purpose and masks the logic of performing API calls. Note that rollbacking to raw clientset should also be transparent.
type FakeRecorder ¶ added in v0.16.4
type FakeRecorder struct {
Events chan string
}
FakeRecorder is used as a fake during tests. It is thread safe. It is usable when created manually and not by NewFakeRecorder, however all events may be thrown away in this case.
func NewFakeRecorder ¶ added in v0.16.4
func NewFakeRecorder(bufferSize int) *FakeRecorder
NewFakeRecorder creates new fake event recorder with event channel with buffer of given size.
