Response Parameters

Status code: 200

**Table 3** Response body parameters
Parameter	Type	Description
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
code	Integer	Suggested HTTP return code for this status, 0 if not set.
details	io.k8s.apimachinery.pkg.apis.meta.v1.StatusDetails object	Extended data associated with the reason. Each reason may define its own extended details. This field is optional and the data returned is not guaranteed to conform to any schema except that defined by the reason type.
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
message	String	A human-readable description of the status of this operation.
metadata	io.k8s.apimachinery.pkg.apis.meta.v1.ListMeta object	Standard list metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
reason	String	A machine-readable description of why this operation is in the "Failure" status. If this value is empty there is no information available. A Reason clarifies an HTTP status code but does not override it.
status	String	Status of the operation. One of: "Success" or "Failure". More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#spec-and-status

**Table 4** io.k8s.apimachinery.pkg.apis.meta.v1.StatusDetails
Parameter	Type	Description
causes	Array of io.k8s.apimachinery.pkg.apis.meta.v1.StatusCause objects	The Causes array includes more details associated with the StatusReason failure. Not all StatusReasons may provide detailed causes.
group	String	The group attribute of the resource associated with the status StatusReason.
kind	String	The kind attribute of the resource associated with the status StatusReason. On some operations may differ from the requested resource Kind. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
name	String	The name attribute of the resource associated with the status StatusReason (when there is a single name which can be described).
retryAfterSeconds	Integer	If specified, the time in seconds before the operation should be retried. Some errors may indicate the client must take an alternate action for those errors this field may indicate how long to wait before taking the alternate action.
uid	String	UID of the resource. (when there is a single resource which can be described). More info: http://kubernetes.io/docs/user-guide/identifiers#uids

**Table 5** io.k8s.apimachinery.pkg.apis.meta.v1.StatusCause
Parameter	Type	Description
field	String	The field of the resource that has caused this error, as named by its JSON serialization. May include dot and postfix notation for nested attributes. Arrays are zero-indexed. Fields may appear more than once in an array of causes due to fields having multiple errors. Optional. Examples: "name" - the field "name" on the current resource "items[0].name" - the field "name" on the first array entry in "items"
message	String	A human-readable description of the cause of the error. This field may be presented as-is to a reader.
reason	String	A machine-readable description of the cause of the error. If this value is empty there is no information available.

**Table 6** io.k8s.apimachinery.pkg.apis.meta.v1.ListMeta
Parameter	Type	Description
continue	String	continue may be set if the user set a limit on the number of items returned, and indicates that the server has more data available. The value is opaque and may be used to issue another request to the endpoint that served this list to retrieve the next set of available objects. Continuing a consistent list may not be possible if the server configuration has changed or more than a few minutes have passed. The resourceVersion field returned when using this continue value will be identical to the value in the first response, unless you have received this token from an error message.
remainingItemCount	Long	remainingItemCount is the number of subsequent items in the list which are not included in this list response. If the list request contained label or field selectors, then the number of remaining items is unknown and the field will be left unset and omitted during serialization. If the list is complete (either because it is not chunking or because this is the last chunk), then there are no more remaining items and this field will be left unset and omitted during serialization. Servers older than v1.15 do not set this field. The intended use of the remainingItemCount is estimating the size of a collection. Clients should not rely on the remainingItemCount to be set or to be exact.
resourceVersion	String	String that identifies the server's internal version of this object that can be used by clients to determine when objects have changed. Value must be treated as opaque by clients and passed unmodified back to the server. Populated by the system. Read-only. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#concurrency-control-and-consistency
selfLink	String	Deprecated: selfLink is a legacy read-only field that is no longer populated by the system.
