Python 无法连接到 docker 中的套接字：PermissionError： [Errno 1] 不允许操作

我有一个应用程序，我正在try 移动到一个 docker 集装箱.我的大部分功能都在运行，但应用程序中需要提升权限的部分(使用套接字和配置网络参数)似乎不起作用.

我试过的是:

• 颁发--privileged面旗帜
• 颁发--cap-add=NET_ADMIN面旗帜
• 使用--security-opt apparmor=unconfined --security-opt seccomp=unconfined删除安全选项
• Adding user groups and sudo in the 文档文件
• 使用--net=host \选项.
• 将我的用户添加到扩展坞组
• 颁发--cap-add=SYS_RAWIO面旗帜
• Adding my user to the netdev group in the 文档文件 RUN groupadd -r netdev && usermod -a -G netdev $USER

这是我收到的错误:

为了理解这个问题，我制作了一个简单的 docker 容器，它有一条失败的线路，并且它起作用了.我不明白为什么它在较大的应用程序中不起作用.以下是最小的示例:
