This is the command i'am running.

If i remove the -v line it works fine. I think this is a Docker issue because it worked before i updated docker.

Can confirm this issue. Reverting to the previous version of Docker Desktop for Windows (Community, v2.2.0.5) fixed this issue. I read through the change log on the Docker website, but I'm not sure what caused the breaking change.

The same is happening here after the most recent update of Docker.

[uncleserge]

Have the same problem after updating Docker Desktop to the recent version (2.3.0.2).

[KVerwold]

Same problem here with version 2.3.0.2 . Even tried to reset Docker to factory defaults, which didn't helped.

[neisep]

Same problem for me, i had to go back to 2.2.0.5.

[Magnavolt]

As a workaround i copy my file in to the container.

docker cp C:\db2\db2-last.bak sqlserver2019:/var/opt/mssql/data/

Confirm, I'm experiencing the same issue after updating to Docker version 2.3.0.2. Any update guys?

Please, there's no need to say "me too" and notify everyone subscribed. That part is obvious.
It's simple:

1. Add 👍 to the original post,
2. Click Subscribe to get notified about the updates,
3. Read previous messages for the workaround,
4. Add comments only if you can contribute some new and useful information,
5. Chill

I'm not sure what caused the breaking change

@TFSM Probably something to do with the following change.

Docker Desktop now allows sharing individual folders, rather than whole drives, giving more control to users over what is being shared.

Same issue!

Docker response: This is a regression in Docker. We will fix it. This ticket can be duped against https://github.com/docker/for-win/issues/6646.
