Access is denied. How to resolve problems with docker cp due to permission on Windows 10?

Question

I'm trying to copy files from my container to the host using:

docker cp aa88c93d0710:/home/app/env/ C:UsersMY_USERNAMEOneDriveDesktopappackend

yielding the following error message: open C:UsersMY_USERNAMEOneDriveDesktopappackendLibsite-packagesFlask-1.1.2.dist-infoentry_points.txt: Access is denied.

However, this is working fine: docker cp aa88c93d0710:/home/app/env/ C:

So I figure that the error is due to docker lacking some permissions on Windows 10? How to resolve this? thanks

Answer 1

I finally fixed this by temporarily disabling Admin Approval Mode in Windows 10:

1. Console secpol.msc
2. Navigate to Security Settings > Local Policies > Security Options
3. Edit properties of User Account Control: Run all administrators in Admin Approval Mode. and set to disabled.

Now, docker cp will copy files from the container to the host as expected, although I'm not happy with the solution.
