Also tried the following:

cmaturi@TECH-P10R95897:~/git/shib-in-a-box$ ls /

Tomorrow let's take a closer look at this link:

microsoft/WSL#1854

[evanjtravis]

Mounting any volumes in WSL requires that they exist as Windows paths in the first place.

Does not work:

 docker run --rm -it -v ~/.aws:/root/.aws debian bash

Works:

 docker run --rm -it -v /c/Users/{NetID}/.aws:/root/.aws debian bash

@evanjtravis and @cmaturi a potential workaround for this problem is to move your home directory to /c/home or some other place on your C: drive. See the following article for details:

https://www.brianketelsen.com/going-overboard-with-wsl-metadata/

The article above is a bit wordy, but the approach is easy enough. Create a /c/home/ directory, copy the contents of your home directory there, then edit /etc/password:

-netid:x:1000:1000:,,,:/home/netid:/bin/bash
+netid:x:1000:1000:,,,:/c/home:/bin/bash

This approach seems straightforward and I think it will work. It is worth a try.

Tried the following in windows cmd prompt. Still seeing the same issue

C:\Users\cmaturi>docker run --rm -it -v "c:\Users\cmaturi":/root/win debian
root@ee645523858c:/# cd /win
bash: cd: /win: No such file or directory
root@ee645523858c:/# cd
root@ee645523858c:~# ls
win
root@ee645523858c:~# cd win
root@ee645523858c:~/win# ls
root@ee645523858c:~/win#

Turns out this is a Windows for Docker issue not a WSL issue. When you change your Windows password, you will NO longer be able to mount you C drive. Since @cmaturi and @evanjtravis are using AD passwords, every time their AD password changes, it will be necessary to unshare your C drive in the Docker for Windows GUI and then reshare it. This requires you to enter your new password. This is a known issue:

docker/for-win#1712

@evanjtravis I am able to mount unix file system using docker:

cmaturi@TECH-P10R95897:/$ docker run --rm -it -v $PWD:/root/win debian  ls -la  /root/win

I am able to mount / and /usr/bin, but I am not able to mount /home . I am also able to mount /c/Users/cmaturi , but not the .aws directory.
