udevadm不显示docker容器中的所有属性

作者：mobiledu2402852413 | 2023-09-06 19:37

如何解决《udevadm不显示docker容器中的所有属性》经验，为你挑选了1个好方法。

当我在容器udevadm内部运行docker container并列出某些设备的属性时,只有该设备的基本信息.当我在主机上做同样的事情时,我可以看到更多.如何获取容器内的所有信息？

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

我还尝试从host:/ sys,/ dev挂载其他卷.没有帮助.

编辑根据Alex P.的回答:

我对udev不太熟悉.我复制了这个

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debug,重新加载配置udevadm control --reload.现在我明白了:

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

现在仍然没有运气.我试图用--privileged标志运行容器,没有帮助.我在/etc/udev/rules.d中没有其他规则.我试图从我的主人那里复制所有规则,没有运气.

如果您只关心从udev数据库获取信息,那么您可以将主机的udev数据库安装到docker容器中,例如,

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

通过这样做,您不需要在docker容器中运行udev守护程序,但仍然可以ID_在执行时获取所有属性udevadm info.这对我来说是在Debian主机上运行的Debian docker容器.

我还建议安装/dev,以便您的docker容器知道设备文件的任何更改.
