Can docker compose build image from different Dockerfiles at the same folder

Question

My containers should share the same source code folder.

But they should build from different Dockerfiles.

Is it possible to build them with docker-compose and build from different Dockerfiles at a time?

I wish there is a syntax like

build: . -f <<Dockerfile_ABC> build: . -f <<Dockerfile_CDE>

abc:
  build: . -f <<Dockerfile_ABC>
  environment:
    - PROJECT=abc
  command: ruby abc/abc.rb
  volumes:
      - ./:/working_direcotry
  ports:
    - 5904:5904

cde:
  build: . -f <Dockerfile_CDE>
  environment:
    - PROJECT=cde
  command: ruby cde/cde.rb
  volumes:
      - ./:/working_direcotry
  ports:
    - 5902:5902

you should be fine to raise pull request to docker github directly for your idea — BMW
Is this a possible repeat of stackoverflow.com/questions/29835905/…. At first I misunderstood this question (ignored the docker-compose part) and wrote an answer. I deleted that answer now, and posted this comment instead haha. — Gobi Dasu

The following worked for me

abc:
  build:
    context: .
    dockerfile: Dockerfile.one
def:
  build:
    context: .
    dockerfile: Dockerfile.two

Of course you can tweak the context as needed if you have different contexts. I also use this to have separate Dockerfile.production versions to set things up differently for production versions of the app.
