How can I set up advanced networking in Docker Compose?

You can set up advanced networking in Docker Compose by defining custom networks in your docker-compose.yml file. Would you like an example?

Yes, please provide an example of a docker-compose.yml file with custom networks.

Sure! Here's a simple example:

version: '3'
services:
  app:
    image: myapp
    networks:
      - frontend
      - backend

  db:
    image: postgres
    networks:
      - backend

networks:
  frontend:
  backend:

This configuration creates two custom networks: frontend and backend. The app service can communicate with both, while the db service can only communicate with the backend.

How do I connect services across different networks?

To connect services across different networks, you can use the external network feature or define a common network in your docker-compose.yml. Would you like to see an example of that?
