How this site is hosted
Normally, when hosting a website, the process goes something like this: You host the site via apache or nginx, bind it to a port on your computer, configure your computers firewall to allow inbound connections to that port, configure your routers firewall to allow inbound connections to that port on that local IP, configure the A and/or AAAA records for your domain on your DNS to point to your IP, and hope it all works.
Without some serious programming, this can cause huge hassles, such as your site being unreachable if your host’s IP address changes. Also, in general, your IP address is public, so anyone with a 5-line Python script and 2 computers can DDOS your website, or scan your IP for open ports, making your host a juicy target for hackers.
I'd rather not get hacked.
So this site is hosted on a Docker container and served to you via Cloudflare Tunnels.

Instead of letting any old computer hold back the horrors of the internet's most hostile of users, hosting the site via a Docker container that automatically tunnels to Cloudflare who will proxy my site for free, reduces my attack surface area via the Docker container emulation on the host computer, and obscures where exactly the user is connecting to.
Cloudflare Tunnels allows you to tunnel a hosted site via an encrypted connection from wherever the site is hosted from in the world, to Cloudflare, who can then distribute the connection anywhere it needs to go. This not only makes it faster by finding very fast routes, but it also allows the container to be launched anywhere without needing to port forward, change firewall settings, or worry about SSL certificates.
This site is also deployed via GitHub, where any push to the (private) GitHub will trigger a GitHub action that compiles the Docker container, notifies the watchtower, and replaces itself seconds after the package is deployed. This allows me to edit the site from anywhere, only ever needing my GitHub credentials.
