Functions

func FromObject 

func FromObject(obj runtime.Object) error

FromObject generates an StatusError from an metav1.Status, if that is the type of obj; otherwise, returns an UnexpecteObjectError.

func IsAlreadyExists 

func IsAlreadyExists(err error) bool

IsAlreadyExists determines if the err is an error which indicates that a specified resource already exists.

func IsBadRequest 

func IsBadRequest(err error) bool

IsBadRequest determines if err is an error which indicates that the request is invalid.

func IsConflict 

func IsConflict(err error) bool

IsConflict determines if the err is an error which indicates the provided update conflicts.

func IsForbidden 

func IsForbidden(err error) bool

IsForbidden determines if err is an error which indicates that the request is forbidden and cannot be completed as requested.

func IsGone 

func IsGone(err error) bool

IsGone is true if the error indicates the requested resource is no longer available.

func IsInternalError 

func IsInternalError(err error) bool

IsInternalError determines if err is an error which indicates an internal server error.

func IsInvalid 

func IsInvalid(err error) bool

IsInvalid determines if the err is an error which indicates the provided resource is not valid.

func IsMethodNotSupported 

func IsMethodNotSupported(err error) bool

IsMethodNotSupported determines if the err is an error which indicates the provided action could not be performed because it is not supported by the server.

func IsNotFound 

func IsNotFound(err error) bool

IsNotFound returns true if the specified error was created by NewNotFound.

func IsResourceExpired 

func IsResourceExpired(err error) bool

IsResourceExpired is true if the error indicates the resource has expired and the current action is no longer possible.

func IsServerTimeout 

func IsServerTimeout(err error) bool

IsServerTimeout determines if err is an error which indicates that the request needs to be retried by the client.

func IsServiceUnavailable 

func IsServiceUnavailable(err error) bool

IsServiceUnavailable is true if the error indicates the underlying service is no longer available.

func IsTimeout 

func IsTimeout(err error) bool

IsTimeout determines if err is an error which indicates that request times out due to long processing.

func IsTooManyRequests 

func IsTooManyRequests(err error) bool

IsTooManyRequests determines if err is an error which indicates that there are too many requests that the server cannot handle.

func IsUnauthorized 

func IsUnauthorized(err error) bool

IsUnauthorized determines if err is an error which indicates that the request is unauthorized and requires authentication by the user.

func IsUnexpectedObjectError 

func IsUnexpectedObjectError(err error) bool

IsUnexpectedObjectError determines if err is due to an unexpected object from the master.

func IsUnexpectedServerError 

func IsUnexpectedServerError(err error) bool

IsUnexpectedServerError returns true if the server response was not in the expected API format, and may be the result of another HTTP actor.

func ReasonForError 

func ReasonForError(err error) metav1.StatusReason

ReasonForError returns the HTTP status for a particular error.

func SuggestsClientDelay 

func SuggestsClientDelay(err error) (int, bool)

SuggestsClientDelay returns true if this error suggests a client delay as well as the suggested seconds to wait, or false if the error does not imply a wait. It does not address whether the error *should* be retried, since some errors (like a 3xx) may request delay without retry.

Types

type APIStatus 

type APIStatus interface {
	Status() metav1.Status
}

APIStatus is exposed by errors that can be converted to an api.Status object for finer grained details.

type StatusError 

type StatusError struct {
	ErrStatus metav1.Status
}

StatusError is an error intended for consumption by a REST API server; it can also be reconstructed by clients from a REST response. Public to allow easy type switches.

func NewAlreadyExists 

func NewAlreadyExists(qualifiedResource schema.GroupResource, name string) *StatusError

NewAlreadyExists returns an error indicating the item requested exists by that identifier.

func NewBadRequest 

func NewBadRequest(reason string) *StatusError

NewBadRequest creates an error that indicates that the request is invalid and can not be processed.

func NewConflict 

func NewConflict(qualifiedResource schema.GroupResource, name string, err error) *StatusError

NewConflict returns an error indicating the item can't be updated as provided.

func NewForbidden 

func NewForbidden(qualifiedResource schema.GroupResource, name string, err error) *StatusError

NewForbidden returns an error indicating the requested action was forbidden

func NewGenericServerResponse 

func NewGenericServerResponse(code int, verb string, qualifiedResource schema.GroupResource, name, serverMessage string, retryAfterSeconds int, isUnexpectedResponse bool) *StatusError

NewGenericServerResponse returns a new error for server responses that are not in a recognizable form.

func NewGone 

func NewGone(message string) *StatusError

NewGone returns an error indicating the item no longer available at the server and no forwarding address is known.

func NewInternalError 

func NewInternalError(err error) *StatusError

NewInternalError returns an error indicating the item is invalid and cannot be processed.

func NewInvalid 

func NewInvalid(qualifiedKind schema.GroupKind, name string, errs field.ErrorList) *StatusError

NewInvalid returns an error indicating the item is invalid and cannot be processed.

func NewMethodNotSupported 

func NewMethodNotSupported(qualifiedResource schema.GroupResource, action string) *StatusError

NewMethodNotSupported returns an error indicating the requested action is not supported on this kind.

func NewNotFound 

func NewNotFound(qualifiedResource schema.GroupResource, name string) *StatusError

NewNotFound returns a new error which indicates that the resource of the kind and the name was not found.

func NewResourceExpired 

func NewResourceExpired(message string) *StatusError

NewResourceExpired creates an error that indicates that the requested resource content has expired from the server (usually due to a resourceVersion that is too old).

func NewServerTimeout 

func NewServerTimeout(qualifiedResource schema.GroupResource, operation string, retryAfterSeconds int) *StatusError

NewServerTimeout returns an error indicating the requested action could not be completed due to a transient error, and the client should try again.

func NewServerTimeoutForKind 

func NewServerTimeoutForKind(qualifiedKind schema.GroupKind, operation string, retryAfterSeconds int) *StatusError

NewServerTimeoutForKind should not exist. Server timeouts happen when accessing resources, the Kind is just what we happened to be looking at when the request failed. This delegates to keep code sane, but we should work towards removing this.

func NewServiceUnavailable 

func NewServiceUnavailable(reason string) *StatusError

NewServiceUnavailable creates an error that indicates that the requested service is unavailable.

func NewTimeoutError 

func NewTimeoutError(message string, retryAfterSeconds int) *StatusError

NewTimeoutError returns an error indicating that a timeout occurred before the request could be completed. Clients may retry, but the operation may still complete.

func NewTooManyRequests 

func NewTooManyRequests(message string, retryAfterSeconds int) *StatusError

NewTooManyRequests creates an error that indicates that the client must try again later because the specified endpoint is not accepting requests. More specific details should be provided if client should know why the failure was limited4.

func NewTooManyRequestsError 

func NewTooManyRequestsError(message string) *StatusError

NewTooManyRequestsError returns an error indicating that the request was rejected because the server has received too many requests. Client should wait and retry. But if the request is perishable, then the client should not retry the request.

func NewUnauthorized 

func NewUnauthorized(reason string) *StatusError

NewUnauthorized returns an error indicating the client is not authorized to perform the requested action.

func (*StatusError) DebugError 

func (e *StatusError) DebugError() (string, []interface{})

DebugError reports extended info about the error to debug output.

func (*StatusError) Error 

func (e *StatusError) Error() string

Error implements the Error interface.

func (*StatusError) Status 

func (e *StatusError) Status() metav1.Status

Status allows access to e's status without having to know the detailed workings of StatusError.

type UnexpectedObjectError 

type UnexpectedObjectError struct {
	Object runtime.Object
}

UnexpectedObjectError can be returned by FromObject if it's passed a non-status object.

func (*UnexpectedObjectError) Error 

func (u *UnexpectedObjectError) Error() string

Error returns an error message describing 'u'.
