Docker - 任何方式可以访问主机USB或串行设备？ [英] Docker - any way to give access to host USB or serial device?

问题描述

上次我检查过， docker 没有任何方法允许容器访问主机串口或USB端口。我想知道是否有任何技巧，任何人都知道哪个允许这样做

Last time I checked, docker didn't have any means to give container access to host serial or USB port. I wonder if there is any trick that anyone here knows which allows doing that

推荐答案

有几个选项。首先，如下面的@Mark所述，docker 1.2.0版（2014/08发布）添加了 - 设备标志，可用于访问USB设备而无需 - 特权模式：

There are a couple of options. First and foremost, as noted by @Mark below, docker version 1.2.0 (released 2014/08) added 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设备可用于驱动程序等主机在 / dev / bus / usb 中，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
