Visual Studio 2017 15.3 Dockerize Database Project - sql-server

Question

Have Visual Studio 2017 (15.3) solution with two projects:
An API written in ASP.NET Core 2 MVC
Database Project
I was able to "dockerize" the MVC project easily (right click, add Docker support) but while trying to dockerize the Database project keep getting the error: Value cannot be null. Parameter name: stream. My Google-fu is failing me; the closest resource found is for Visual Studio 15.2.
How I've Setup Database Project So Far
Added Dockerfile to root:
FROM microsoft/mssql-server-linux:latest
EXPOSE 1433
ENV ACCEPT_EULA=Y
ENV LANG en_US.UTF-8
ENV LANGUAGE en_US:en
ENV LC_ALL en_US.UTF-8
ENV MSSQL_TCP_PORT=1433
# Add Database project output from VS build process
RUN mkdir --parents /_scripts/generated
COPY ./_scripts /_scripts/
COPY ./_scripts/generated/*.sql /_scripts/generated/
# Add shell script that starts MSSQL server, waits 60 seconds, then executes script to build out DB (script generated from VS build process)
CMD /bin/bash /_scripts/entrypoint.sh
Modified docker-compose.yml file to include new project
version: '3'
services:
webapp-api-service:
image: webapp-api
build:
context: ./src/API
dockerfile: Dockerfile
webapp-db-service:
image: webapp-db
build:
context: ./src/Database
dockerfile: Dockerfile
Modified docker-composeoverride.yml file to expose port for dev SSMS access
version: '3'
services:
webapp-api-service:
environment:
- ASPNETCORE_ENVIRONMENT=Development
ports:
- "80"
webapp-db-service:
ports:
- "1433"
Here's the build output
2>C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\MSBuild\Sdks\Microsoft.Docker.Sdk\build\Microsoft.VisualStudio.Docker.Compose.targets(279,5): error : Value cannot be null.

Thanks in advance!

Answer 1

I ran into this same issue yesterday. I just solved it by removing the build portion of the database service. I'll just have to build the database project manually for now.

Answer 2

You can add a file named AppType.cache to /obj/Docker with content AspNetCore as a workaround.
