How do I set up a network in Docker Compose?

To set up a network in Docker Compose, you can define it in your docker-compose.yml file under the networks section.

Can you show me an example of a docker-compose.yml file with a network?

Sure! Here's a simple example:

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

networks:
  mynetwork:
    driver: bridge

What does the 'driver' option do in the network configuration?

The 'driver' option specifies the network driver to use. The default is 'bridge', which creates an isolated network.

Can I connect multiple services to the same network?

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