Docker - 一种访问主机 USB 或串行设备的方法? [英] Docker - a way to give access to a host USB or serial device?

问题描述

我上次检查时，Docker 没有任何方法可以让容器访问主机串行或 USB 端口.有没有允许这样做的技巧?

Last time I checked, Docker didn't have any means to give container access to host serial or USB port. Is there a trick which allows doing that?

推荐答案

有几个选项.您可以使用 --device 标志，用于在没有 --privileged 模式的情况下访问 USB 设备:

There are a couple of options. You can use the --device flag that use can use to access USB devices without --privileged mode:

docker run -t -i --device=/dev/ttyUSB0 ubuntu bash

或者，假设您的 USB 设备可在 /dev/bus/usb 中的主机上运行驱动程序等，您可以使用 特权模式 和 卷选项.例如:

Alternatively, assuming your USB device is available with drivers working, etc. on the host in /dev/bus/usb, you can mount this in the container using privileged mode and the volumes option. For example:

docker run -t -i --privileged -v /dev/bus/usb:/dev/bus/usb ubuntu bash

请注意，顾名思义，--privileged 是 不安全，应小心处理.

Note that as the name implies, --privileged is insecure and should be handled with care.
