udevadm不会在docker容器中显示所有属性

本文介绍了udevadm不会在docker容器中显示所有属性的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

当我运行docker容器并列出容器中带有 udevadm 的某些设备的属性时，只有关于设备的基本信息。当我在主机上执行相同的操作时，我可以看到更多。我该怎么办才能获取容器内的所有信息？

When I run docker container and list properties of some device with udevadm inside the container, there are only the basic information about the device. When I do the same thing on host, I can see much more. What can I do to get all the information inside the container?

host$ udevadm info --query=property /dev/bus/usb/004/008
BUSNUM=004
DEVNAME=/dev/bus/usb/004/008

host$ docker run -ti -v /dev/bus/usb/:/dev/bus/usb alpine sh
container# apk update
container# apk add eudev
container# udevadm info --query=property /dev/bus/usb/004/008

我也尝试过从主机上挂载其他卷：/ sys，/ dev。没有帮助。

I have also tried to mount other volumes from host: /sys, /dev. Did not help.

编辑根据的答案：

我对udev不太了解。我已经复制了这个

I'm not very experienced with udev. I have copied this

SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", IMPORT{builtin}="usb_id", IMPORT{builtin}="hwdb --subsystem=usb"

到/ dev / udev / rules.d / 10-local.rules，我已将udev日志设置为调试，并使用 udevadm控件--reload 重新加载了配置。现在我得到了：

to /dev/udev/rules.d/10-local.rules, I have set udev logging to debug, reloaded config with udevadm control --reload. Now I get this:

calling: info
P: /devices/pci0000:00/0000:00:1d.0/usb4/4-1/4-1.2
N: bus/usb/004/016
no db file to read /run/udev/data/c189:399: No such file or directory
E: BUSNUM=004
E: DEVNAME=/dev/bus/usb/004/016
E: DEVNUM=016
E: DEVPATH=/devices/pci0000:00/0000:00:1d.0/usb4/4-1/4-1.2

E: DRIVER=usb
E: MAJOR=189
E: MINOR=399
E: PRODUCT=4d8/de/2
E: SUBSYSTEM=usb
E: TYPE=0/0/0

目前仍然没有运气。
我尝试使用--privileged标志运行容器，没有帮助。我在/etc/udev/rules.d中没有其他规则。我试图从主机上复制所有规则，没有运气。

For now still no luck.I tried to run the container with --privileged flag, did not help. I have no other rules in /etc/udev/rules.d. I tried to copy all rules from my host, no luck.

host$ udevadm monitor --environment
    monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent

推荐答案

如果仅关心从udev数据库获取信息，则可以将主机的udev数据库挂载到docker中容器，例如

If you only care about getting information from the udev database, then you can mount the host's udev database into the docker container, e.g.,

-v /run/udev:/run/udev:ro

这样做，您无需在docker容器中运行udev守护程序，但仍然可以获得所有执行 udevadm信息时ID _ 属性。对于在Debian主机上运行的Debian Docker容器，这对我有用。

By doing so, you won't need to run a udev daemon inside the docker container, but still get all the ID_ attributes when doing udevadm info. This worked for me for a Debian docker container running on a Debian host.

我还建议将 / dev 挂载为好，这样您的Docker容器就会知道设备文件的任何更改。

I also suggest mounting /dev as well so your docker container will know about any changes to the device files.

这篇关于udevadm不会在docker容器中显示所有属性的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
