How do I set up custom networks in Docker Compose?

To set up custom networks in Docker Compose, you can define networks in your docker-compose.yml file. Here's a basic example:

version: '3'
services:
  app:
    image: myapp
    networks:
      - my_custom_network

networks:
  my_custom_network:
    driver: bridge

What are the benefits of using custom networks?

Custom networks allow you to isolate services, control communication between them, and manage DNS resolution more effectively.

Can I connect multiple services to the same custom network?

Yes, you can connect multiple services to the same custom network by listing the network under each service in your docker-compose.yml.

How do I remove a custom network?

You can remove a custom network using the command docker network rm <network_name>, but ensure no containers are using it.
