Variables

var ErrExit = fmt.Errorf("exit")

ErrExit may be passed to CheckError to instruct it to output nothing but exit with status code 1.

Functions

func BehaviorOnFatal

func BehaviorOnFatal(f func(string, int))

BehaviorOnFatal allows you to override the default behavior when a fatal error occurs, which is to call os.Exit(code). You can pass 'panic' as a function here if you prefer the panic() over os.Exit(1).

func CheckErr

func CheckErr(err error)

CheckErr prints a user friendly error to STDERR and exits with a non-zero exit code. Unrecognized errors will be printed with an "error: " prefix.

This method is generic to the command in use and may be used by non-Kubectl commands.

func DefaultBehaviorOnFatal

func DefaultBehaviorOnFatal()

DefaultBehaviorOnFatal allows you to undo any previous override. Useful in tests.

func Fatal

func Fatal(msg string, code int)

Fatal prints the message (if provided) and then exits. If V(2) or greater, glog.Logger().Fatal is invoked for extended information.

func StandardErrorMessage

func StandardErrorMessage(err error) (string, bool)

StandardErrorMessage translates common errors into a human readable message, or returns false if the error is not one of the recognized types. It may also log extended information to glog.

This method is generic to the command in use and may be used by non-Kubectl commands.

func UsageError

func UsageError(cmd *cobra.Command, format string, args ...interface{}) error

UsageError prints an error with how to run the help for the specified command.
