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

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

.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

fieldValidation

string

fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. 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.
