示例1: parseDockerExposeOpt

//based on expose opt parsing in Docker
func parseDockerExposeOpt(values []string) (map[docker.Port]struct{}, error) {
	exposedPorts := map[docker.Port]struct{}{}

	for _, raw := range values {
		if strings.Contains(raw, ":") {
			return nil, fmt.Errorf("Invalid EXPOSE format: %s", raw)
		}

		proto, ports := nat.SplitProtoPort(raw)
		startPort, endPort, err := nat.ParsePortRange(ports)
		if err != nil {
			return nil, fmt.Errorf("Invalid port range in EXPOSE: %s / error: %s", raw, err)
		}

		for i := startPort; i <= endPort; i++ {
			portInfo, err := nat.NewPort(proto, strconv.FormatUint(i, 10))
			if err != nil {
				return nil, err
			}

			exposedPorts[docker.Port(portInfo)] = struct{}{}
		}
	}
	return exposedPorts, nil
}
