deploy-rs VS poetry2nix

deploy-rs

Deploy-rs is a great alternative. It works as wrapper on top of flakes, local (optionally, cross-) building and copying closures to target machine with activation:

The SSH key I made for this uses yubikey authentication, and every time this opens a SSH connection it will ask for the key. There's some options you can add so multiple SSH sessions can use a single connection, but the current version isn't really working well with them (see e.g. https://github.com/serokell/deploy-rs/issues/106)

I haven't really been in the market for something like this in a long while, but NixOS solved a lot of my headaches when it comes to maintaining a VPS and I'd like to try giving this a shot again. I'm not really interested in cloud/microservice/docker/cluser/whatever, I just want to use something like deploy-rs with a single host and maybe a VPN service like tailscale. What sorts of providers would y'all recommend?

I've messed around with deploy.rs. Simple enough to know what's going on.

There are 4 tools I'm taking into consideration right now, but every suggestion is welcome: 1. deploy-rs - I don't know anything about it, heard about it like a day or two ago 2. NixOps - the official one, I don't know what to think, but I have concerns about Flakes compatibility 3. morph - I understand this as "NixOps, but better", no more toughs. 4. colmena - seems to be pretty straightforward with quite nice docs

deploy-rs is great for this as well

How about converting it to Nix derivation?

https://github.com/nix-community/poetry2nix

This looks really strange because I do not know how to solve it and also because it looks like the sha256 that I am setting is not the one that Nix will match. I read also https://github.com/nix-community/poetry2nix/issues/413 but I was not able to solve the problem.

There's a project that does this with using Nix: https://github.com/takeda/nix-cde (this is a wrapper around https://github.com/nix-community/poetry2nix)

{ description = "Application packaged using poetry2nix"; inputs.flake-utils.url = "github:numtide/flake-utils"; inputs.nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable"; inputs.poetry2nix = { url = "github:nix-community/poetry2nix"; inputs.nixpkgs.follows = "nixpkgs"; }; outputs = { self, nixpkgs, flake-utils, poetry2nix }: flake-utils.lib.eachDefaultSystem (system: let # see https://github.com/nix-community/poetry2nix/tree/master#api for more functions and examples. inherit (poetry2nix.legacyPackages.${system}) mkPoetryEnv; pkgs = import nixpkgs {inherit system;}; python = pkgs.python310; pythonEnv = mkPoetryEnv { inherit python; projectDir = ./.; preferWheels = true; }; in { #packages.default = mkPoetryEnv { # projectDir = ./.; # python = pkgs.python310; #}; devShells.default = pkgs.mkShell { buildInputs = [pythonEnv]; packages = [ poetry2nix.packages.${system}.poetry pkgs.cairo pkgs.pkg-config pkgs.gobject-introspection pkgs.tk ]; }; }); }

A cleaner way might be to use https://github.com/nix-community/poetry2nix which can load poetry.lock inside Nix. I still need to try it for torch, but it does seem like a clean way to use it.

The README for poetry2nix (https://github.com/nix-community/poetry2nix) seems to indicate that all extras should be enabled by default.

if it's for a project you're working on, i'd recommend just using poetry2nix

poetry2nix is another popular option.
