Creating a Network in Docker Compose

To create a network in Docker Compose, you will need to define it in a docker-compose.yml file. Here's a step-by-step explanation:

1. Create a docker-compose.yml file if you haven't already.
2. Under the services section, define your services.
3. Add a networks section at the bottom of the file.
4. Specify the network name and additional settings if necessary.
5. Link the services to the network by adding a networks tag under each service.

Here's an example snippet:

version: '3'
services:
webapp:
image: my-webapp
networks:
- mynetwork
networks:
mynetwork:
driver: bridge

This docker-compose file snippet defines a bridge network named mynetwork and associates the webapp service with it.
