Functions ¶
func GetFieldSelector ¶ added in v0.22.0
func GetFieldSelector(eventsGroupVersion schema.GroupVersion, regardingGroupVersionKind schema.GroupVersionKind, regardingName string, regardingUID types.UID) (fields.Selector, error)
GetFieldSelector returns the appropriate field selector based on the API version being used to communicate with the server. The returned field selector can be used with List and Watch to filter desired events.
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()
// StartStructuredLogging starts sending events received from this EventBroadcaster to the structured
// logging function. The return value can be ignored or used to stop recording, if desired.
StartStructuredLogging(verbosity klog.Level) 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 EventBroadcasterAdapter
deprecated
added in
v0.19.0
type EventBroadcasterAdapter interface {
// StartRecordingToSink starts sending events received from the specified eventBroadcaster.
StartRecordingToSink(stopCh <-chan struct{})
// NewRecorder creates a new Event Recorder with specified name.
NewRecorder(name string) EventRecorder
// DeprecatedNewLegacyRecorder creates a legacy Event Recorder with specific name.
DeprecatedNewLegacyRecorder(name string) record.EventRecorder
// Shutdown shuts down the broadcaster.
Shutdown()
}
EventBroadcasterAdapter is a auxiliary interface to simplify migration to the new events API. It is a wrapper around new and legacy broadcasters that smartly chooses which one to use.
Deprecated: This interface will be removed once migration is completed.
func NewEventBroadcasterAdapter ¶ added in v0.19.0
func NewEventBroadcasterAdapter(client clientset.Interface) EventBroadcasterAdapter
NewEventBroadcasterAdapter creates a wrapper around new and legacy broadcasters to simplify migration of individual components to the new Event API.
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 *eventsv1.Event) (*eventsv1.Event, error)
Update(event *eventsv1.Event) (*eventsv1.Event, error)
Patch(oldEvent *eventsv1.Event, data []byte) (*eventsv1.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 typedeventsv1.EventsV1Interface
}
EventSinkImpl wraps EventsV1Interface 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.
func (*EventSinkImpl) Create ¶
Create takes the representation of a event and creates it. Returns the server's representation of the event, and an error, if there is any.
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.
