Error mounting a config file into the container

3. click the security tab
4. click the "Edit" button.
5. click the add button
6. Type "users" in the text box
7. click "Check Names" (should auto fill/update for you)
8. click okay
9. Highlight your newly added group.
10. Under "Permissions for [User/Groupname]" select Full control
11. click apply
12. Click "OK"

Answer 2

(I added the same problem few minutes ago.)

Make sure your docker is allowed to mount the directory C:\Users\[redacted]\Documents\Docker

Configuration

In the Windows client, you can configure the docker to allow read/write on specific drives. This should fix your permissions problem.

Already configured ?

In my case, it was already selected. I unchecked and checked the drive again. Apply the "change". It prompted me for my Windows password (which had change) and than the mount worked again.
