🔗 Elixir clustering on a Kamal + Hetzner deployment

I've been experimenting with Kamal for deploying an Elixir application. The application was previously deployed on Fly.io and relies on the Erlang VM's clustering capabilities, so I had to get this working on the Hetzner deployment I'd spun up using Kamal.

It took me a bit of effort to get the clustering setup working, so here are my notes on what I did to get it working. It's also not a perfect setup at the moment, so if you have any suggestions do let me know!
