I have a solution with 2 projects :

• angular app
• webapi asp core app

Angular app docker file :

FROM node:10
WORKDIR ClientApp
COPY package.json . 
RUN npm install
COPY . .
EXPOSE 4200
CMD npm start

My docker compose :

services:
  webapplication1:
    image: ${DOCKER_REGISTRY-}webapplication1
    build:
      context: .
      dockerfile: WebApplication1/Dockerfile
    environment:
    - ASPNETCORE_ENVIRONMENT=Development
    ports:
    - "8050:80"

  webapplication7:
    build:
      context: ./WebApplication7/ClientApp
      dockerfile: ./WebApplication7/Dockerfile
    ports:
    - 4200:4200

I’m trying to use docker compose to dockerize both apps, which works fine with docker-compose up command
the issue is that I cannot use visual studio build-in debugger because my angular image does not depend on dotnet. Therefore, I get message that debug target is not valid or debugger cannot find a Program class.

Documentation/tutorials are so rare on this topic but even though I managed to find this tutorial, I’ve found out that there are some missing steps.

I also tried to ignore the build of the angular project but it did not work either.

Can someone please provide some help ? thank you.
