Reverse Proxy setup

How I put my very own personal servers online, for free.

This sets up a reverse proxy using nginx on a VM in fly.io using tailscale to access the internal servers.

When adding a new hostname, remember to create a cert for it using flyctl certs create hostname

Every 90 days the tailscale auth key will expire and you need to set a new one as a secret.

Create the new one at https://login.tailscale.com/admin/settings/keys (MAKE IT REUSABLE)
Configure it using flyctl secrets set TAILSCALE_AUTHKEY={{PASTEKEYHERE}}
