Another command I continue to lose, or the SERPs only show me how to install docker (opposite of what I want!)
How-to: Uninstall Docker CLI, and Container packages.
Straight Code on how to remove docker:
sudo apt-get purge docker-ce docker-ce-cli containerd.io
sudo rm -rf /var/lib/docker
Pastebin:
Second part is to delete images, containers, volumes, or customized configuration files on your host. These are not automatically removed.
