Starting with Docker on Ubuntu in WSL 2 without Docker Desktop

These are the steps I use to run Docker without using Docker Desktop.

Ensure you are using WSL 2 by running wsl --list --verbose in PowerShell.
Then from a WSL2 bash shell...
Completely uninstall Docker: https://askubuntu.com/q/935569
Install docker using the repository https://docs.docker.com/engine/install/ubuntu/
Start the daemon sudo service docker start .
Test that docker works sudo docker run hello-world .
