flake: add Nix flake for reproducible builds #1096
Conversation
Enable building rustfs with Nix package manager. It allows using rustfs on x86_64-linux, aarch64-linux, x86_64-darwin, and aarch64-darwin. Upstream (nixpkgs) can later adopt this package definition to provide cached builds for users of Nix. The next step is to add a NixOS module. I have a stub one already in my niks3 binary cache that I use for [testing](https://github.com/Mic92/niks3/blob/8fbef7d5a3d551d0f1dc663fe91f94c3e3edf85e/nix/checks/nixos-test-niks3.nix) that would need some love to be upstream-worthy (i.g. I hard-code s3 credentials)

Hey @Mic92 , |

I tested this on:
What scope of NixOS integration do you want to have?
|

Hey @Mic92 , Our goal is simply to allow NixOS users to get RustFS (SNSD) up and running quickly. For advanced RustFS needs, we prefer to direct users to consult experts like you for commercial support. I believe that is the most reasonable approach. However, if you have a better suggestion, we would value your professional advice on this. Thank you! |
I split the docs out into a separate PR, so details can be discussed here: #1103 |

Pull request overview
This PR adds Nix flake support to enable reproducible builds of RustFS across multiple platforms (x86_64-linux, aarch64-linux, x86_64-darwin, and aarch64-darwin). The implementation provides a standard Nix package definition that can be integrated into nixpkgs for cached binary distribution to Nix users.
Key Changes:
- Adds
flake.nixwith complete build configuration using Rust Platform - Includes properly configured dependencies (protobuf, pkg-config, openssl)
- Provides
flake.lockpinning nixpkgs to a recent unstable snapshot

Tests are disabled during the Nix build with doCheck = false. Since the project has comprehensive test coverage across multiple crates, consider enabling tests in the Nix build. If tests are disabled due to specific requirements (e.g., external dependencies, network access, or long build times), this should be documented in a comment explaining the rationale.
