Ubuntu 20.04 - Install Docker
The script below will install docker using a PPA. This will allow you to always use the latest version of Docker without waiting on the Ubuntu package maintainers. Normally I would recommend installing from the Ubuntu Repos, but with docker this method is what I recommend.
#!/bin/bash sudo apt update && sudo apt dist-upgrade -y # Remove any existing installations... sudo apt-get purge docker-engine -y sudo apt-get remove docker docker-engine docker.io -y # Stop script on any error # need to set this AFTER purge so that doesn't error out on fresh install set -e sudo apt update sudo apt install -y \ software-properties-common apt-transport-https ca-certificates curl # Add the key for docker 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" apt-cache policy docker-ce sudo apt update sudo apt install docker-ce -y # Add the current user to docker so that you can # execute docker commands without using sudo sudo usermod -aG docker $USER echo "You will need to reboot before using docker."
