Types

type Event

type Event struct {
	api.TypeMeta `json:",inline"`

	api.ObjectMeta `json:"metadata" protobuf:"bytes,1,opt,name=metadata"`

	// eventTime is the time when this Event was first observed. It is required.
	EventTime api.MicroTime `json:"eventTime" protobuf:"bytes,2,opt,name=eventTime"`

	// series is data about the Event series this event represents or nil if it's a singleton Event.
	// +optional
	Series *EventSeries `json:"series,omitempty" protobuf:"bytes,3,opt,name=series"`

	// reportingController is the name of the controller that emitted this Event, e.g. `kubernetes.io/kubelet`.
	// This field cannot be empty for new Events.
	ReportingController string `json:"reportingController,omitempty" protobuf:"bytes,4,opt,name=reportingController"`

	// reportingInstance is the ID of the controller instance, e.g. `kubelet-xyzf`.
	// This field cannot be empty for new Events and it can have at most 128 characters.
	ReportingInstance string `json:"reportingInstance,omitempty" protobuf:"bytes,5,opt,name=reportingInstance"`

	// action is what action was taken/failed regarding to the regarding object. It is machine-readable.
	// This field cannot be empty for new Events and it can have at most 128 characters.
	Action string `json:"action,omitempty" protobuf:"bytes,6,name=action"`

	// reason is why the action was taken. It is human-readable.
	// This field cannot be empty for new Events and it can have at most 128 characters.
	Reason string `json:"reason,omitempty" protobuf:"bytes,7,name=reason"`

	// regarding contains the object this Event is about. In most cases it's an Object reporting controller
	// implements, e.g. ReplicaSetController implements ReplicaSets and this event is emitted because
	// it acts on some changes in a ReplicaSet object.
	// +optional
	Regarding api.ObjectReference `json:"regarding,omitempty" protobuf:"bytes,8,opt,name=regarding"`

	// related is the optional secondary object for more complex actions. E.g. when regarding object triggers
	// a creation or deletion of related object.
	// +optional
	Related *api.ObjectReference `json:"related,omitempty" protobuf:"bytes,9,opt,name=related"`

	// note is a human-readable description of the status of this operation.
	// Maximal length of the note is 1kB, but libraries should be prepared to
	// handle values up to 64kB.
	// +optional
	Note string `json:"note,omitempty" protobuf:"bytes,10,opt,name=note"`

	// type is the type of this event (Normal, Warning), new types could be added in the future.
	// It is machine-readable.
	// This field cannot be empty for new Events.
	Type string `json:"type,omitempty" protobuf:"bytes,11,opt,name=type"`

	// deprecatedSource is the deprecated field assuring backward compatibility with core.v1 Event type.
	// +optional
	DeprecatedSource api.EventSource `json:"deprecatedSource,omitempty" protobuf:"bytes,12,opt,name=deprecatedSource"`
	// deprecatedFirstTimestamp is the deprecated field assuring backward compatibility with core.v1 Event type.
	// +optional
	DeprecatedFirstTimestamp api.Time `json:"deprecatedFirstTimestamp,omitempty" protobuf:"bytes,13,opt,name=deprecatedFirstTimestamp"`
	// deprecatedLastTimestamp is the deprecated field assuring backward compatibility with core.v1 Event type.
	// +optional
	DeprecatedLastTimestamp api.Time `json:"deprecatedLastTimestamp,omitempty" protobuf:"bytes,14,opt,name=deprecatedLastTimestamp"`
	// deprecatedCount is the deprecated field assuring backward compatibility with core.v1 Event type.
	// +optional
	DeprecatedCount int32 `json:"deprecatedCount,omitempty" protobuf:"varint,15,opt,name=deprecatedCount"`
}

Event is a report of an event somewhere in the cluster. It generally denotes some state change in the system. Events have a limited retention time and triggers and messages may evolve with time. Event consumers should not rely on the timing of an event with a given Reason reflecting a consistent underlying trigger, or the continued existence of events with that Reason. Events should be treated as informative, best-effort, supplemental data.

type EventList

type EventList struct {
	api.TypeMeta `json:",inline"`
	// Standard list metadata.
	// More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata
	// +optional
	api.ListMeta `json:"metadata,omitempty" protobuf:"bytes,1,opt,name=metadata"`

	// items is a list of schema objects.
	Items []Event `json:"items" protobuf:"bytes,2,rep,name=items"`
}

EventList is a list of Event objects.

type EventSeries

type EventSeries struct {
	// count is the number of occurrences in this series up to the last heartbeat time.
	Count int32 `json:"count" protobuf:"varint,1,opt,name=count"`
	// lastObservedTime is the time when last Event from the series was seen before last heartbeat.
	LastObservedTime api.MicroTime `json:"lastObservedTime" protobuf:"bytes,2,opt,name=lastObservedTime"`
}

EventSeries contain information on series of events, i.e. thing that was/is happening continuously for some time. How often to update the EventSeries is up to the event reporters. The default event reporter in "k8s.io/client-go/tools/events/event_broadcaster.go" shows how this struct is updated on heartbeats and can guide customized reporter implementations.
