Notes by @bruderol

Installed docker according to https://docs.docker.com/install/linux/docker-ce/ubuntu

Those were the commands I used

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 $(lsb_release -cs) stable"
sudo apt-get update
sudo apt-get install docker-ce
