instruction: Create a Dockerfile for compose
output: ```dockerfile
  from Docker
  Compose and used to group the containers together. By default, the project name is simply the name of the directory that the
  compose.yaml was located in.If you expand the stack, you'll see the two containers you defined in the Compose file. The names are also a little
  more descriptive, as they follow the pattern of <service-name>-<replica-number>. So, it's very easy to
  quickly see what container is your app and which container is the mysql database.Tear it all downWhen you're ready to tear it all down, simply run docker compose down or hit the trash can on the Docker Desktop Dashboard
  for the entire app. The containers will stop and the network will be removed.
  WarningBy default, named volumes in your compose file are not removed when you run docker compose down. If you want to
  remove the volumes, you need to add the --volumes flag.The Docker Desktop Dashboard does not remove volumes when you delete the app stack.SummaryIn this section, you learned about Docker Compose and how it helps you simplify
  the way you define and share multi-service applications.Related information:Compose overviewCompose file referenceCompose CLI referenceNext stepsNext, you'll learn about a few best practices you can use to improve your Dockerfile.Image-building best practices
