2.1. Specification

PropertyTypeDescription

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

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

spec

object

spec defines the characteristics of the resource.

status

object

status contains the observed state of the resource.

PropertyTypeDescription

numberOfUsersToReport

integer

numberOfUsersToReport is the number of users to include in the report. If unspecified or zero, the default is ten. This is default is subject to change.

Type
object
PropertyTypeDescription

conditions

array

conditions contains details of the current status of this API Resource.

conditions[]

object

Condition contains details for one aspect of the current state of this API Resource. --- This struct is intended for direct use as an array at the field path .status.conditions. For example, type FooStatus struct{ // Represents the observations of a foo’s current state. // Known .status.conditions.type are: "Available", "Progressing", and "Degraded" // +patchMergeKey=type // +patchStrategy=merge // +listType=map // +listMapKey=type Conditions []metav1.Condition json:"conditions,omitempty" patchStrategy:"merge" patchMergeKey:"type" protobuf:"bytes,1,rep,name=conditions" // other fields }

currentHour

object

currentHour contains request history for the current hour. This is porcelain to make the API easier to read by humans seeing if they addressed a problem. This field is reset on the hour.

last24h

array

last24h contains request history for the last 24 hours, indexed by the hour, so 12:00AM-12:59 is in index 0, 6am-6:59am is index 6, etc. The index of the current hour is updated live and then duplicated into the requestsLastHour field.

last24h[]

object

PerResourceAPIRequestLog logs request for various nodes.

removedInRelease

string

removedInRelease is when the API will be removed.

requestCount

integer

requestCount is a sum of all requestCounts across all current hours, nodes, and users.

  • status
  • type
PropertyTypeDescription

lastTransitionTime

string

lastTransitionTime is the last time the condition transitioned from one status to another. This should be when the underlying condition changed. If that is not known, then using the time when the API field changed is acceptable.

message

string

message is a human readable message indicating details about the transition. This may be an empty string.

observedGeneration

integer

observedGeneration represents the .metadata.generation that the condition was set based upon. For instance, if .metadata.generation is currently 12, but the .status.conditions[x].observedGeneration is 9, the condition is out of date with respect to the current state of the instance.

reason

string

reason contains a programmatic identifier indicating the reason for the condition’s last transition. Producers of specific condition types may define expected values and meanings for this field, and whether the values are considered a guaranteed API. The value should be a CamelCase string. This field may not be empty.

status

string

status of the condition, one of True, False, Unknown.

type

string

type of condition in CamelCase or in foo.example.com/CamelCase. --- Many .condition.type values are consistent across resources like Available, but because arbitrary conditions can be useful (see .node.status.conditions), the ability to deconflict is important. The regex it matches is (dns1123SubdomainFmt/)?(qualifiedNameFmt)

dryRun

string

When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed

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.
