Commands are relative to a corresponding docker-compose.yml file

To use a base .yml and an extended one:
> docker-compose -f docker-compose.yml -f docker-compose-2.yml up -d

To get logs:

Volumes

Volumes are stored by default in /var/lib/docker/volumes.

volumes:
  my-volume:

services:
  app:
    volumes:
      - my-volume:/path-in-container

Networking

By default docker-compose will create a new network for the given compose file. You can change the behavior by defining custom networks in your compose file.

Create and assign custom network

networks:
  custom-network:

services:
  app:
    networks:
      - custom-network

Use existing networks

If you want to use an existing Docker network for your compose files, you can add the external: true parameter in your compose file

networks:
  existing-network:
    external: true
