Combining multiple Compose files into one

We have created various environments by combining compose files. This will assist the development process; however, it will make it more complex. Compose gives us the option to combine the various compose files used for the various use cases into one.

Using config

Note that config is a Docker compose command that will merge the files specified.

For example, we can try it when we want to run the location service as standalone:

docker compose -f base-compose.yaml -f location-service/docker-compose.yaml config

The result will be the unified JSON:

name: chapter7
services:
  location-service:
    build:
      context: /path/to/git/A-Developer-s-Essential-Guide-to-Docker-Compose/Chapter7/location-service
      dockerfile: Dockerfile
    depends_on:
      redis:
     ...
