Setup Hyper-V enhanced session for Ubuntu 20

I couldn't find instructions that were 100% complete, so I put this together.

These instructions worked fine for me. Follow each step carefully.

Download Ubuntu 20 desktop

DO NOT create the VM by choosing Quick Create in Hyper-V Manager. Follow these instructions exactly.

The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.

The correct way of creating a private frok by duplicating the repo is documented here.

For this assignment the commands are:

1. Create a bare clone of the repository. (This is temporary and will be removed so just do it wherever.)

git clone --bare [email protected]:usi-systems/easytrace.git

Deploy Rocket using Letsencrypt and nginx

Information

This guide uses the domain your-domain.tld and its www. prefixed version. It starts the rocket application on 127.0.0.1:1337 and as the user www-data. The proxy listens on port 80 and 443 though.
If you need other values, update them accordingly in your nginx and systemd configs.

Prerequisites

You need to have nginx, certbot and rust installed.
