How To Install Docker on Ubuntu 20.04

Docker is an application that simplifies the process of managing application processes in containers. Containers run your applications in resource-isolated processes. Containers are similar to virtual machines, but they are more portable, resource-friendly, and dependent on the host operating system.

In this tutorial, we will install Docker on Ubuntu 20.04 and use basic commands to get you started.

sudo apt update

sudo apt-get install apt-transport-https ca-certificates curl software-properties-common

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

Step 4: Installing the Docker Repository
