DockerCompose for ASP.NET Core API App and Angular6 App

Question

Good day,

I'm new with docker. I have 2 projects that have dockerfiles in each of them.

My projects are: ASP.NET Core API and Angular6

In my ASP.NET Core API project, here's my working dockerfile

FROM microsoft/dotnet:2.1-aspnetcore-runtime
ARG source
WORKDIR /app
EXPOSE 80
COPY ${source:-obj/DockerPublishedApp} .
ENTRYPOINT ["dotnet", "myapp.dll"]

I did manually published my app and it stores in my DockerPublishedApp.

In my Angular6 project, here's my working dockerfile.

FROM nginx:1.13.3-alpine
RUN rm -rf /usr/share/nginx/html/*
COPY /dist/mypublishedangularapp /usr/share/nginx/html
CMD ["nginx","-g","daemon off;"]

Both these dockerfiles are working properly when I build and run them one by one.

My main concern is, how can I convert them to docker-compose.yml to avoid running the created image one by one.

Suppose you have the following directory structure:

/proj1
        /Dockerfile
    /proj2
        /Dockerfile
    /docker-compose.yml

You could have the following compose file:

version: '3.4'

    services:
      proj1:
        image: proj1:latest     
        build:
          context: ./proj1
          dockerfile: Dockerfile

      proj2:
        image: proj2:latest     
        build:
          context: ./proj2
          dockerfile: Dockerfile

And run docker-compose -f docker-compose.yml up --build to build both images and run them. This will build images proj1:latest and proj2:latest.

Alternatively, if you did not want to build them, just remove the build keys, and omit --build.

To run publish out of the Dockerfile:

version: '3.4'

    services:
      proj1:
        image: proj1:latest     
        build:
          context: ./proj1
          dockerfile: Dockerfile 
        command: dotnet publish ...
