Chapter Summary

In this chapter, you learned how to deploy and manage multi-container applications using Docker Compose.

• Compose is now fully integrated into the Docker Engine and has its own docker compose sub-command. It lets you define multi-container applications in declarative configuration files and deploy them with a single command.

• Compose files define all the containers, networks, volumes, secrets, and other configurations an application needs. You then use the docker compose command to post the Compose file to Docker, and Docker deploys it.
