connect two application running separatly on docker-compose

I have a django application with mysql (chatbot) and rails application with mongodb each run over docker-compose They both running separately I want to connect them together, how can i accomplish that ???

My docker-compose file with rails

#with rails on the dockerfile
version: '3.6'
services:
  db:
    image: mongo:latest
    volumes:
      - ./tmp/db:/var/lib/mongo/data
  web:
    build: .
    command: bundle exec rails s -p 3000 -b '0.0.0.0'
    volumes:
      - .:/IMS
    ports:
      - "3000:3000"
    depends_on:
      - db
  bundle:
    image: ims_web
    volumes:
      - /bundle

The django prroject :

#with django on the dockerfile
version: '3.6'
services:
  db:
    image: mysql:latest
    volumes:
      - ./tmp/db:/var/lib/mysql/data
  web:
    build: .
    command: bundle exec rails s -p 4000 -b '0.0.0.0'
    volumes:
      - .:/SDV
    ports:
      - "4000:4000"
    depends_on:

If these applications are meant to be run together, I would suggest combining your docker-compose files here and identifying each service with a unique name (i.e., don't duplicate service names, call them mongo-db and mysql-db or something -- same with the web services).

At that point, so long as all of your services share a common network, you will be able to intercommunicate by using the service name as hostname. For example, you can hit your new rails-web service from django-web via http://rails-web/.

See Hemant's answer for Docker networking documentation.

You just need to make sure that the containers you want to talk to each other are on the same network. You need to create a custom network in your docker compose files.

For more reference, you can refer to https://docs.docker.com/compose/networking/
