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.

And because I don't like contrived examples, we're going to do something somewhat real-world: we're going to geo-locate visitors, and track how many visits we get from each country.

Now that our service is production-ready, it's time to deploy it somewhere.

There's a lot of ways to approach this: what we are going to do, though, is build a docker image. Or, I should say, an OCI image.

This is still a series about Nix, but again: because the best way to see the benefits of Nix is to do it without Nix first, we'll use only Docker's tooling to build the image.

I often give bits and pieces of advice on how to build Rust stuff the comfy way. But it can be hard to see how everything comes together, especially when it comes to, say, deploying a web service in production.

So, let's start from the very beginning (setting up a Linux VM), and march together towards the objective: a production-grade Rust web service, built with Nix.
