It's very strange to imagine that you'd host a DB in a conceptually local manner to application services. This couples things in a way that's very awkward for scaling. Even if you're not using containers, you almost never organize deploys this way outside of beta/dev environments. And if you were to make such a decision, then you'd capture it in the closure required to run the code you built, so you'd sort of bake in the inclusion of those services into any deploy of your code, using Nix's philosophy. Or am I misunderstanding you?
