How can I use Docker Compose for advanced configurations?

Docker Compose allows you to define and run multi-container Docker applications. For advanced configurations, you can use features like overrides, environment variables, and custom networks.

Can you explain how to use override files?

Sure! Override files allow you to customize your Docker Compose setup without modifying the original docker-compose.yml. You can create a file named docker-compose.override.yml and Docker Compose will automatically use it.

What about using environment variables in my Compose file?

You can define environment variables in your docker-compose.yml file using the env_file option or directly in the service definition. This helps keep sensitive data out of your configuration.

How do I set up custom networks in Docker Compose?

To set up custom networks, you can define networks in your docker-compose.yml file under the networks section and then specify which services should use those networks.
