Chapter 7. Event [events.k8s.io/v1] Description 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 object Required eventTime 7.1. Specification Property Type Description action string 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. apiVersion string APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources deprecatedCount integer deprecatedCount is the deprecated field assuring backward compatibility with core.v1 Event type. deprecatedFirstTimestamp Time deprecatedFirstTimestamp is the deprecated field assuring backward compatibility with core.v1 Event type. deprecatedLastTimestamp Time deprecatedLastTimestamp is the deprecated field assuring backward compatibility with core.v1 Event type. deprecatedSource EventSource deprecatedSource is the deprecated field assuring backward compatibility with core.v1 Event type. eventTime MicroTime eventTime is the time when this Event was first observed. It is required. kind string Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds metadata ObjectMeta Standard object's metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata note string 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. reason string 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. regarding ObjectReference 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. related ObjectReference related is the optional secondary object for more complex actions. E.g. when regarding object triggers a creation or deletion of related object. reportingController string reportingController is the name of the controller that emitted this Event, e.g. kubernetes.io/kubelet . This field cannot be empty for new Events. reportingInstance string 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. series object 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. type string 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. 7.1.1. .series Description 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. Type object Required count lastObservedTime Property Type Description count integer count is the number of occurrences in this series up to the last heartbeat time. lastObservedTime MicroTime lastObservedTime is the time when last Event from the series was seen before last heartbeat. 7.2. API endpoints The following API endpoints are available: /apis/events.k8s.io/v1/events GET : list or watch objects of kind Event /apis/events.k8s.io/v1/watch/events GET : watch individual changes to a list of Event. deprecated: use the 'watch' parameter with a list operation instead. /apis/events.k8s.io/v1/namespaces/{namespace}/events DELETE : delete collection of Event GET : list or watch objects of kind Event POST : create an Event /apis/events.k8s.io/v1/watch/namespaces/{namespace}/events GET : watch individual changes to a list of Event. deprecated: use the 'watch' parameter with a list operation instead. /apis/events.k8s.io/v1/namespaces/{namespace}/events/{name} DELETE : delete an Event GET : read the specified Event PATCH : partially update the specified Event PUT : replace the specified Event /apis/events.k8s.io/v1/watch/namespaces/{namespace}/events/{name} GET : watch changes to an object of kind Event. deprecated: use the 'watch' parameter with a list operation instead, filtered to a single item with the 'fieldSelector' parameter. 7.2.1. /apis/events.k8s.io/v1/events HTTP method GET Description list or watch objects of kind Event Table 7.1.

Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered. Table 7.7. Body parameters Parameter Type Description body Event schema Table 7.8.
