Chapter 8. Event [v1] Description Event is a report of an event somewhere in the cluster. 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 metadata involvedObject 8.1. Specification Property Type Description action string What action was taken/failed regarding to the Regarding object. 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 count integer The number of times this event has occurred. eventTime MicroTime Time when this Event was first observed. firstTimestamp Time The time at which the event was first recorded. (Time of server receipt is in TypeMeta.) involvedObject object ObjectReference contains enough information to let you inspect or modify the referred object. 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 lastTimestamp Time The time at which the most recent occurrence of this event was recorded. message string A human-readable description of the status of this operation. metadata ObjectMeta Standard object's metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata reason string This should be a short, machine understandable string that gives the reason for the transition into the object's current status. related object ObjectReference contains enough information to let you inspect or modify the referred object. reportingComponent string Name of the controller that emitted this Event, e.g. kubernetes.io/kubelet . reportingInstance string ID of the controller instance, e.g. kubelet-xyzf . series object EventSeries contain information on series of events, i.e. thing that was/is happening continuously for some time. source object EventSource contains information for an event. type string Type of this event (Normal, Warning), new types could be added in the future 8.1.1. .involvedObject Description ObjectReference contains enough information to let you inspect or modify the referred object. Type object Property Type Description apiVersion string API version of the referent. fieldPath string If referring to a piece of an object instead of an entire object, this string should contain a valid JSON/Go field access statement, such as desiredState.manifest.containers[2]. For example, if the object reference is to a container within a pod, this would take on a value like: "spec.containers{name}" (where "name" refers to the name of the container that triggered the event) or if no container name is specified "spec.containers[2]" (container with index 2 in this pod). This syntax is chosen only to have some well-defined way of referencing a part of an object. kind string Kind of the referent. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds name string Name of the referent. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names/#names namespace string Namespace of the referent. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/namespaces/ resourceVersion string Specific resourceVersion to which this reference is made, if any. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#concurrency-control-and-consistency uid string UID of the referent. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names/#uids 8.1.2. .related Description ObjectReference contains enough information to let you inspect or modify the referred object.

More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names/#uids 8.1.3. .series Description EventSeries contain information on series of events, i.e. thing that was/is happening continuously for some time. Type object Property Type Description count integer Number of occurrences in this series up to the last heartbeat time lastObservedTime MicroTime Time of the last occurrence observed 8.1.4. .source Description EventSource contains information for an event. Type object Property Type Description component string Component from which the event is generated. host string Node name on which the event is generated. 8.2.
