Docker Compose is a tool that allows you to define and orchestrate multi-container Docker applications. It uses a YAML file to configure the application’s containers, networks, and volumes.

Compose can be used for various purposes. Single host application deployments, automated testing, and local development are the most popular use cases for Docker Compose.

This tutorial will walk through the process of installing the latest version of Docker Compose on Debian 9. We’ll also explore the basic Docker Compose concepts and commands.

Prerequisites

Ensure that you have met the following prerequisites before continuing with this tutorial:

• Logged in as a user with sudo privileges .
• Have Docker installed on your Debian 9 machine.

Install Docker Compose on Debian

The Docker Compose installation package is available in the official Debian 9 repositories but it may not always be the latest version. The recommended approach is to install Docker Compose from the Docker’s GitHub repository.

At the time of writing this article, the latest stable version of Docker Compose is version 1.23.1. Before downloading the Compose binary visit the Compose repository release page on GitHub and check if there is a new version available for download.

1. Perform the following steps to install the latest version of Docker Compose on Debian 9:Start by downloading the Docker Compose binary into the /usr/local/bin directory using the following [curl](https://linuxize.com/post/curl-command-examples/) command:

sudo curl -L "https://github.com/docker/compose/releases/download/1.23.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

1. When the download is complete, give executable permissions to the Compose binary:

sudo chmod +x /usr/local/bin/docker-compose

1. Verify the installation by typing:

docker-compose --version

1. The output will look something like this:

docker-compose version 1.23.1, build b02f1306
