udevadm不显示泊坞窗容器内的所有属性
当我运行docker容器并在容器内部列出一些设备的属性时，只有设备的基本信息。 当我在主持人做同样的事情，我可以看到更多。 我能做些什么来获得容器内的所有信息？

我也尝试从主机：/ sys，/ dev挂载其他卷。 没有帮助。
按照Alex P.的回答编辑：
我不是很有经验的udev。 我已经复制了这个
SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", IMPORT{builtin}="usb_id", IMPORT{builtin}="hwdb --subsystem=usb"
到/dev/udev/rules.d/10-local.rules，我已经设置udevloggingdebugging，重新加载configuration与udevadm control --reload 。 现在我明白了这一点：
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: DEVTYPE=usb_device E: DRIVER=usb E: MAJOR=189 E: MINOR=399 E: PRODUCT=4d8/de/2 E: SUBSYSTEM=usb E: TYPE=0/0/0
现在还没有运气。 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。 我试图从我的主机复制所有规则，没有运气。

如果您只关心从udev数据库获取信息，则可以将主机的udev数据库挂载到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守护进程，但是在执行udevadm info时仍然可以获得所有的ID_属性。 这对我在Debian主机上运行的Debian docker容器起作用。
我也build议安装/dev ，以便您的docker容器将知道设备文件的任何更改。
添加下面的udev规则来填充ID_属性：
SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", IMPORT{builtin}="usb_id", IMPORT{builtin}="hwdb --subsystem=usb"
根据这个博客，udev在容器中运行时并不能很好地与docker配合使用。 因此，我决定这个问题需要一个解决方法。 使用udev，我只能在/ sys中获取设备的path，并直接从该path获取所需的信息，例如：
container# cat "/sys$(udevadm info -q path /dev/bus/usb/002/009)/idVendor"
我打算把这个标记为已解决，但这只是一个解决方法，而不是问题的真正答案。
编辑
根据这篇文章 ，这些标志是需要得到udevadm显示udev事件（以及属性）：–net = host -v / dev：/ dev
这只适用于udevadm monitor ，不适用于udevadm info 。
