Note: Even though the Prerequisites give instructions for installing Docker on Debian 10, the docker commands in this article should work on other operating systems as long as Docker is installed.

Docker installed with the instructions from Step 1 and Step 2 of How To Install and Use Docker on Debian 10.This initial server setup with Debian 10 tutorial explains how to set this up. A Debian 10 server and a non-root user with sudo privileges.

In this tutorial, you’ll install the latest version of Docker Compose to help you manage multi-container applications on a Debian 10 server.

Docker Compose lets users orchestrate the processes of Docker containers, including starting up, shutting down, and setting up intra-container linking and volumes. This became so popular that the Docker team decided to make Docker Compose based on the Fig source, which is now deprecated. The Docker community came up with a popular solution called Fig, which allowed you to use a single YAML file to orchestrate all of your Docker containers and configurations. For complex applications with a lot of components, orchestrating all the containers to start up, communicate, and shut down together can quickly become unwieldy. Docker is a great tool for automating the deployment of Linux applications inside software containers, but to take full advantage of its potential each component of an application should run in its own individual container.
