Installing Docker on Ubuntu Server 20.04

I was looking to set up a new server for a caching service that ran via Docker but the first step was to get Docker set up on a new Ubuntu Server install so I thought I would document the steps I took to get it installed, mainly for future reference so I don’t have to hit up Google for the process that works.

After the new install, make sure to perform an apt update and apt upgrade so you have all of the new packages installed.

Next you will want to install the following packages

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

Next grab the GPG key from the Docker repository

curl -fsSL | sudo apt-key add -

Then grab the Docker repository APT sources so you can actually install Docker

sudo add-apt-repository "deb [arch=amd64] focal stable"

Now go ahead and install Docker

sudo apt install docker-ce

That’s it, you should not be able to run Docker on your Ubuntu Server 20.04
