挂载文件至容器疑问

[mba1398]

使用如下命令挂载时，可以完成挂载，但是使用 docker inspect containerID 命令查看容器信息时， Mounts KEY 是空值，看不到配置信息，请问这是为什么呢？

docker run --rm -it --mount type=bind,source=/mnt/e/test.txt,target=/var/log/abc.txt ubuntu:18.04 bash

ps: 当前只有一个 ubuntu:18.04 容器是启动的。

你可以贴上 docker inspect containerID 命令的执行结果

win10+wsl2 环境，docker inspect 2c6521e3b598 返回信息如下：（容器启动状态下）
