Question

我使用ubuntu 17.04运行服务器。我决定尝试使用docker来完成我的新项目。我意识到docker不能很好地使用防火墙，因为它可以自行改变iptables。所以我浏览了docker docs并发现你可以通过使用这样的标志创建json文件来防止这种情况发生：

/etc/docker/daemon.json

{
          "iptables": false
}

但是在尝试重新启动docker守护程序后，我遇到了一个错误：

Job for docker.service failed because the control process exited with error code.
See "systemctl status docker.service" and "journalctl -xe" for details.

有人知道如何解决这个问题吗？

修改

<小时/> 运行dockerd -D命令输出后如下所示：

unable to configure the Docker daemon with file /etc/docker/daemon.json: invalid character 'Ã' looking for beginning of object key string

将iptables设置为false后，Docker无法启动
