如何将 USB 无线接口连接到 Mac OS X 上的 Docker 容器？

Question

我有一个 Linux Docker 容器，它需要一个无线接口才能工作。在 Linux 上（在 Linux 主机上运行它）我没有问题。

带参数运行泊坞窗容器--privileged和--net=host我可以访问该主机的无线接口，并没有任何问题，我可以管理它们。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>
gif0: flags=8010<POINTOPOINT,MULTICAST> mtu 1280
stf0: flags=0<> mtu 1280
en0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
    options=b<RXCSUM,TXCSUM,VLAN_HWTAGGING>
    ether 00:0c:29:fe:78:07
    inet6 fe80::8ff:62ac:e141:5aa9%en0 prefixlen 64 secured scopeid 0x4
    inet 192.168.0.153 netmask 0xffffff00 broadcast 192.168.0.255
    nd6 options=201<PERFORMNUD,DAD>
    media: autoselect (1000baseT <full-duplex>)
    status: active
en1: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
    ether 00:c0:ca:5a:00:f2
    nd6 options=201<PERFORMNUD,DAD>
    media: autoselect (<unknown type>)
    status: inactive

    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
        inet 172.17.0.1  netmask 255.255.0.0  broadcast 0.0.0.0

        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10<host>
        loop  txqueuelen 1  (Local Loopback)
        RX packets 3  bytes 54 (54.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 3  bytes 54 (54.0 B)

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

我如何在 Mac OS X 上实现这一目标？如果我--net=host从命令行中删除Docker 来启动 Docker，则接口会docker0在容器内消失……区别在于，但无论如何都不会出现无线接口。
