Types

type APIStatus

type APIStatus interface {
	Status() api.Status
}

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

type ErrorReporter

type ErrorReporter struct {
	// contains filtered or unexported fields
}

ErrorReporter converts generic errors into runtime.Object errors without requiring the caller to take a dependency on meta/v1 (where Status lives). This prevents circular dependencies in core watch code.

func NewClientErrorReporter

func NewClientErrorReporter(code int, verb string, reason string) *ErrorReporter

NewClientErrorReporter will respond with valid v1.Status objects that report unexpected server responses. Primarily used by watch to report errors when we attempt to decode a response from the server and it is not in the form we expect. Because watch is a dependency of the core api, we can't return meta/v1.Status in that package and so much inject this interface to convert a generic error as appropriate. The reason is passed as a unique status cause on the returned status, otherwise the generic "ClientError" is returned.

func (*ErrorReporter) AsObject

func (r *ErrorReporter) AsObject(err error) interface{}

AsObject returns a valid error runtime.Object (a v1.Status) for the given error, using the code and verb of the reporter type. The error is set to indicate that this was an unexpected server response.

type StatusError

type StatusError struct {
	ErrStatus api.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(name string) *StatusError

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

func NewApplyConflict

func NewApplyConflict(causes []api.StatusCause, message string) *StatusError

NewApplyConflict returns an error including details on the requests apply conflicts

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(name string, err error) *StatusError

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

func NewForbidden

func NewForbidden(name string, err error) *StatusError

NewForbidden returns an error indicating the requested action was forbidden

func NewGenericServerResponse

func NewGenericServerResponse(code int, verb string, 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. DEPRECATED: Please use NewResourceExpired instead.

func NewInternalError

func NewInternalError(err error) *StatusError

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

func NewInvalid

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

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

func NewMethodNotSupported

func NewMethodNotSupported(action string) *StatusError

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

func NewNotFound

func NewNotFound(name string) *StatusError

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

func NewRequestEntityTooLargeError

func NewRequestEntityTooLargeError(message string) *StatusError

NewRequestEntityTooLargeError returns an error indicating that the request entity was too large.

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(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(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{})

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

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

type UnexpectedObjectError

type UnexpectedObjectError struct {
	Object interface{}
}

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'.
