Everything about docker
Wait wait wait, so we're not talking about nix yet?
Well, no! The service we have is pretty simple, and I want to complicate things a bit, to show how things would work in both the Dockerfile and the nix scenario.
Disclosure: Because I used to work for fly.io, I still benefit from an employee discount at the time of this writing: I don't have to pay for anything deployed there for now.
