Sure. You can read through the Docker documentation to find out how to Docker on Ubuntu. Or… You can just copy-paste the commands below.

Uninstall old versions of Docker

sudo apt-get remove docker docker-engine docker.io containerd runc

Add the Docker apt repository

sudo apt-get updatesudo apt-get install \
    apt-transport-https \
    ca-certificates \
    curl \
    gnupg-agent \
    software-properties-commoncurl -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"

Install Docker Engine

sudo apt-get updatesudo apt-get install docker-ce docker-ce-cli containerd.io

Manage Docker as a non-root user

There is courage. There is temperance. Laches and Charmides. For the courageous folks, follow the Post-installation steps for Linux.

sudo groupadd dockersudo usermod -aG docker $USERnewgrp docker

Reboot to make sure the new permissions stick.

sudo reboot

Verify that Docker Engine is installed correctly

docker run hello-world
