internal

Documentation

Overview

Package internal is needed to break an import cycle: record.EventRecorderAdapter needs this interface definition to implement it, but event.NewEventBroadcasterAdapter needs record.NewBroadcaster. Therefore this interface cannot be in event/interfaces.go.

Types

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 EventRecorderLogger

type EventRecorderLogger interface {
	EventRecorder

	// WithLogger replaces the context used for logging. This is a cheap call
	// and meant to be used for contextual logging:
	//    recorder := ...
	//    logger := klog.FromContext(ctx)
	//    recorder.WithLogger(logger).Eventf(...)
	WithLogger(logger klog.Logger) EventRecorderLogger
}

EventRecorderLogger extends EventRecorder such that a logger can be set for methods in EventRecorder. Normally, those methods uses the global default logger to record errors and debug messages. If that is not desired, use WithLogger to provide a logger instance.
