How can I set up a multi-service application using Docker Compose?

To set up a multi-service application with Docker Compose, you'll need to create a docker-compose.yml file that defines your services.

What should I include in the docker-compose.yml file?

You should define each service, including the image, ports, and any dependencies. Here's a basic example:

version: '3'
services:
  web:
    image: nginx
    ports:
      - '80:80'
  db:
    image: postgres
    environment:
      POSTGRES_PASSWORD: example

How do I start the services after creating the file?

You can start the services by running docker-compose up in the directory where your docker-compose.yml file is located.

Can I run the services in the background?

Yes, you can run the services in the background by using the -d flag: docker-compose up -d.
