Docker Compose download and installation instructions
1.Compose instructions
Docker Compose is a tool for defining and managing multiple Docker containers, designed to simplify the development, deployment, and management of containerized applications. With Docker Compose, you can use a single configuration file (usually a configuration docker-compose.ymlfile) to describe multiple containers, network settings, storage volumes, etc. involved in your application.

1.1 Overview of installing Docker Compose
Important information :
- Starting in July 2023, Compose V1 will stop receiving updates. It is also no longer included in new versions of Docker Desktop.
- Compose V2 is included in all currently supported versions of Docker Desktop. For more information, see Migrating to Compose V2 .
- Docker's documentation mentions and describes the capabilities of Compose V2.
1.2 Installation scenarios
1.2.1 Scenario one: Install Docker Desktop
The easiest and recommended way to get Docker Compose is to install Docker Desktop. Docker Desktop includes Docker Compose as well as the Docker Engine and Docker CLI, which are prerequisites for Compose.
1.2.2 Scenario two: Install the Compose plugin
If you have installed Docker Engine and Docker CLI, you can install the Compose plug-in through the command line. There are two methods:
- Software repository via Docker
- Download and install manually
IMPORTANT : Supports Linux only
1.2.3 Scenario three: Install the Compose standalone
You can install Compose stand-alone on Linux or Windows Server.
Warning : This installation scenario is not recommended and is supported for backward compatibility only.
