Question

我有一个Linux Docker容器，需要无线接口才能工作。在Linux上（在Linux主机上运行）我没有问题。

使用参数--privileged和--net=host运行Docker容器我可以访问主机无线接口，我可以毫无问题地管理它们。问题是当我在Mac OS X主机上运行相同的Linux Docker容器时。我看不到Docker容器内的无线接口。

这是Mac OS X v10.12（Sierra）主机上ifconfig的输出：

lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
    options=1203<RXCSUM,TXCSUM,TXSTATUS,SW_TIMESTAMP>
    inet 127.0.0.1 netmask 0xff000000
    inet6 ::1 prefixlen 128
    inet6 fe80::1%lo0 prefixlen 64 scopeid 0x1
    nd6 options=201<PERFORMNUD,DAD>

“en1”接口是无线USB设备。现在容器内的ifconfig输出使用描述的参数运行：

docker0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500

我猜容器的eth0被“映射”到en0接口并且正在工作，我在容器内部可以访问Internet。但是，为什么我没有看到en1映射到容器上的任何设备？

如何在Mac OS X上实现此目的？如果我从命令行中删除--net=host以启动Docker，则接口docker0在容器内消失...是不同的，但无论如何都不会出现无线接口。

如何在Mac OS X上将USB无线接口连接到Docker容器？
