Github Actions for Phoenix App Deployment to Hetzner

Recently I started hosting wishlist palace on a Hetzner CX23 VPS (that has 4 GB of ram and 2 vcpu). At work usually I package software into a container before deploying it. One of the reasons I chose Elixir and Phoenix as the tech stack for wishlist palace is that I wanted to try out mix releases which prepare binaries. OS and chip architecture Originally I was just going to compile on my local machine (A thinkpad T480) and upload to the server. But this didn't work because the VPS I had provisioned was running ubuntu 24.04 LTS and my local machine is on EndevousOS (a flavor of Arch by-the-way). So rather than local build and push, I opted to get claude to build a series of github actions that would build on a worker that was running ubuntu. This had the added benefit of basically completely setting up a basic CI loop so that when a release is cut we build a new binary and deploy it on the server. Elixir's mix release creates a self-contained binary that bundles the Erlang VM along wit
