Docker is a software platform that helps us to build, test and deploy our applications without delay. Docker bundle our software into standardized units called containers. Containers that have all the necessary elements which the software needs to run including libraries, system tools, code, and runtime. Using Docker, you can quickly deploy and scale applications into any environment and know your code will run.
Docker Compose is a tool that was developed to help define and share multi-container applications. With Compose, we can create a YAML file to define the services. It creates fully customized environments with multiple containers that have the capability to share data volumes and networks using service definitions.
This post will help you to learn how to install Docker Compose on Ubuntu 22.04.
Download Docker Compose:

$ sudo curl -L ttps://github.com/docker/compose/releases/download/v2.7.0/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose
The above command download the latest version of docker compose from github and store it on our local bin.
In next step we have to set the correct permission for the downloaded tool to execute the docker compose command on Ubuntu using the following command.
$ sudo chmod +x /usr/local/bin/docker-compose
