How to Install and Use Docker on Ubuntu 20.04

Docker is a most popular, open-source platform for developers and system administrators to build, run, and share applications with containers. Containerization (the use of containers to deploy applications) is becoming popular because containers are flexible, lightweight, portable, loosely coupled, scalable, and more secure.

This article is a good starting point for beginners to learn how to install and use Docker on a Ubuntu 20.04 Linux system with some basic commands. For this guide, we will install Docker Community Edition (CE).

Prerequisites:

Installing Docker on Ubuntu 20.04

To use the latest version of Docker, we will install it from the official Docker repository. So, start by adding the GPG key for the official Docker repository to your system, after that add the repository configuration to the APT source with the following commands.

$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
$ sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu focal stable"

Now update the APT package cache to include the new Docker packages to the system using the following command.
