示例1: InstallFlags

// InstallFlags adds command-line options to the top-level flag parser for
// the current process.
func (options *Options) InstallFlags(cmd *flag.FlagSet, usageFn func(string) string) {
	options.Mirrors = opts.NewListOpts(ValidateMirror)
	cmd.Var(&options.Mirrors, []string{"-registry-mirror"}, usageFn("Preferred Docker registry mirror"))

示例2: ParseFlags

// ParseFlags is a utility function that adds a help flag if withHelp is true,
// calls cmd.Parse(args) and prints a relevant error message if there are
// incorrect number of arguments. It returns error only if error handling is
// set to ContinueOnError and parsing fails. If error handling is set to
// ExitOnError, it's safe to ignore the return value.
// TODO: move this to a better package than utils
func ParseFlags(cmd *flag.FlagSet, args []string, withHelp bool) error {
	var help *bool
	if withHelp {
		help = cmd.Bool([]string{"#help", "-help"}, false, "Print usage")
	}
	if err := cmd.Parse(args); err != nil {
		return err
	}
	if help != nil && *help {

		os.Exit(0)
	}
	if str := cmd.CheckArgs(); str != "" {
		ReportError(cmd, str, withHelp)
	}
	return nil
