Install Docker Compose on Ubuntu 20.04 - Step by step process to perform it ?

This article covers how to install and run Docker Compose on your Ubuntu 20.04 LTS machine. Docker Compose is yet another useful Docker tool. It allows users to launch, execute, communicate, and close containers with a single coordinated command. Essentially, Docker Compose is used for defining and running multi-container Docker applications.


To Install Docker Compose on Ubuntu:

1. Start by updating the default repository to ensure you download the latest Docker Compose:

$ sudo apt update

2. Then, upgrade the system to ensure all local packages and programs are up to date:

3. Then install Docker Compose from the Ubuntu repository by running:

$ sudo apt install docker-compose

This message means curl is installed.

However, if the terminal says "command not found", you need to install curl with:

$ sudo apt install curl
