Shared Drives not applying #78

Expected behavior

Entering correct credentials in the Windows Security dialog after sharing a drive will successfully share the drive with containers

Actual behavior

When sharing a drive, entering correct credentials re-opens the Windows Security dialog with no perceivable action taken.


It looks like action might be taken and the drive is shared but it is unclear from the UI. Here is a snippet of the diagnostic log

[20:43:50.458][Auth           ][Info   ] Storing credentials: mlm:***

[20:43:50.513][SambaShare     ][Info   ] "C" is shared
[20:43:50.515][SambaShare     ][Info   ] Challenging credentials with host

Steps to reproduce the behavior

  1. Open the Docker for Windows Settings
  2. Go to the "Shared Drives" tab
  3. Check the "C" drive and Press "Apply"
  4. Enter the credentials for your admin account in the Windows Security dialog and press "OK"
  5. Note the Windows Security dialog popping up again. Entering in credentials again just pops it again.
  6. If you just exit the Windows Security dialog, the "C" drive isn't checked

It looks like the Hyper-V driver machines can't mount volumes so I was looking into this option, moby/moby#22981 (comment)

Hi @MadLittleMods, thanks for the detailed report! Could you give a try to the Beta channel instead of the Stable channel? It contains multiple fixes to the file sharing.

@MadLittleMods could you please upload a diagnostic dump (it's in the Docker tray icon menu) so we can get more info about your system?

Sorry @friism, I moved on to Docker Toolbox and VirtualBox driver. I would need to reinstall Docker for Windows and do the Hyper-V dance again.

@MadLittleMods I'm afraid I will have to close this issue as "Could not reproduce" then. Next version of Docker for Windows will have an improved file sharing that should solve similar issues. Feel free to reopen this ticket if you come back to using Docker for Windows!

A little more information on this, Having the same issue. I am running windows 10 pro on Parallels. My user on the Parallels VM which has admin rights is what I use when i enter credentials. After entering, the dialog closes and check box is unchecked. However if i create an new user for the VM at the Machine level not Company level, it works fine. however i would prefer to use the machine with my domain account.

I also have a domain account, same symptoms (Windows 10). So maybe the problem is domain account vs local account?
