multiple containers?

docker-compose -f ./docker-compose.yml -f ./somewhereelse/docker-compose.yml -f ./1/2/3/docker-compose.yml up?

To use multiple override files, or an override file with a different name, you can use the -f option to specify the list of files. Compose merges files in the order they’re specified on the command line. See the docker-compose command reference for more information about using-f.

can have multiple Dockerfiles but they need to be in different directories

docker-compose.yml
docker
├── web
│   └── Dockerfile
└── db
    └── Dockerfile

version: '3'
services:
  web:
    # will build ./docker/web/Dockerfile
    build: ./docker/web
    ports:
     - "5000:5000"
    volumes:
     - .:/code
  db:
    # will build ./docker/db/Dockerfile
    build: ./docker/db
    ports:
      - "3306:3306"
  redis:
    # will use docker hub's redis prebuilt image from here:
    # https://hub.docker.com/_/redis/
    image: "redis:alpine"

# The following command will create and start all containers in the background
# using docker-compose.yml from current directory
docker-compose up -d

# get help
docker-compose --help

---

in case you need in the directory above

version: '3'
services:
  web:
    build:
      context: .
      dockerfile: ./docker/web/Dockerfile
    ports:
     - "5000:5000"
    volumes:
     - .:/code
