Installing Docker in your Linux System

Docker lets you manage applications inside of a container. A container is an application that lets you run your applications in a resource-isolated environment. Dockers are predictable, portable, and lightweight. Today we will talk about installing Docker on Linux machines. I am using Ubuntu 18.04, and while the process mostly remains the same, make sure to cross-check!

Let’s get started!

Pre-requisites

You are adding a few prerequisite packages, getting the GPG keys and then adding docker to the apt sources

sudo apt update
sudo apt install apt-transport-https ca-certificates curl software-properties-common
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 bionic stable"

Update Package database

sudo apt update

Installing Docker

apt-cache policy docker-cesudo apt install docker-ce

Testing if it has installed

sudo systemctl status docker

There you go! You are done! Now head back to whatever other tutorials you came here from!
