Docker Deskop 2.3.0.2 for Windows - Host Volumes Stopped Working

I have a compose (yml) file that I use to bring servers up and down as I need them. I have just updated my Docker Desktop on Windows to version 2.3.0.2.

My Sql Server instance will not stay running now.

My yaml file is simply:

 version: '3.2'

services:  
  dev-mssql-server:
    image: mcr.microsoft.com/mssql/server
    container_name: dev-mssql-server
    volumes:
      - type: bind
        source: C:\Data\sqlserver-linux-container
        target: /var/opt/mssql/data
    networks:
      dvlpnet:
        ipv4_address:  172.22.0.20
    environment:
      - ACCEPT_EULA=Y
      - SA_PASSWORD=ReallyBitchin#1Password
      - MSSQL_PID=Developer
    ports:
      - "15785:1433"

networks:
  dvlpnet:
    ipam:
      config:
        - subnet:  172.22.0.0/24

volumes:
  sqlserver-linux-container:

And the message from the Docker Dashboard is:

And some of the Docker log file is here:

I made sure that my C drive was still shared properly in the new version of Docker Desktop. I even redundantly added c:\data and c:\data\sqlserver-linux-container directories as shared after I started seeing these errors.

I was not able to find much out on the interwebbies on how this new version of Docker Desktop handles Windows host volumes.

I removed version 2.3.0.2 and reinstalled the older version 2.2.0.5 and everything worked happily again.

Has anyone run into this? Is there a solution yet that I was not able to find?

We have same problem. Our scouting showed that:

• Docker Desktop 2.3.0.2 (changelog)

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

• Microsoft suggests mapping subdirectories separately:

https://docs.microsoft.com/en-us/sql/linux/sql-server-linux-configure-docker?view=sql-server-ver15#mount-a-host-directory-as-data-volume

      mssql:
        container_name:  $PROJECTNAME-mssql
        restart: ${DOCKER_RESTART}
        image: "mcr.microsoft.com/mssql/server:2019-CU4-ubuntu-16.04"
        volumes:
          # konfiguracja dla lokalnej bazy mssql na dockerze
          - ./var/data/mssql/data:/var/opt/mssql/data
          - ./var/data/mssql/log:/var/opt/mssql/log
          - ./var/data/mssql/secrets:/var/opt/mssql/secrets

Still doesn't work.

Edit:

There is an active issue registered on github related to this one:
