Nix Flake all the things or use alongside Docker?

[Kodylow]

Made a first pass at building the flake.nix today and got it working with the rust build and environment variables.

Should the flake.nix run the entire project as a standalone, so build and use its own postgres and redis through nix without docker, or do you want it to run alongside docker? Can do either one.

Good question - though I have nix I haven't used flakes yet. What is more common? I guess it would be good to support both for ppl not on the nix train yet.
I'm thinking probably not using docker at all is more idiomatic for a flakes.nix setup isn't it? Perhaps we start with that to experiment but we can change it if needed.

More common to do everything through nix but I see that you're using docker for the rest of the stack so wanted to check. I think making it as a standalone could be helpful for starting to decouple from the galoy backend , could do work in nix shell and update the nix environment variables as a sandbox to avoid breaking your regular ci/cd and https://github.com/fort-nix/nix-bitcoin is great for testing integrations against other bitcoin and lightning node implementations once stablesats gets to that point.
