Motivation for this change

To host a Mindustry server on NixOS via services configuration.
Note that mindustry can open up a socket connection when setup via e.g.

      services.mindustry = {
        enable = true;
        extraConfig.socketInput = true;
      };

This can then be used to send commands to the server (it only listens on localhost) with e.g. nc

echo "shuffle" | nc -w1 127.0.0.1 6859

I am not 100% happy with that, if anyone has gotten some ideas I'd be glad to hear them.

Also, I am not sure how I would be able to implement a graceful shutdown of mindustry-server, again feedback welcome.

Things done
  • Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS linux)
  • Built on platform(s)
    • NixOS
    • macOS
    • other Linux distributions
  • Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
  • Tested compilation of all pkgs that depend on this change using nix-shell -p nixpkgs-review --run "nixpkgs-review wip"
  • Tested execution of all binary files (usually in ./result/bin/)
  • Determined the impact on package closure size (by running nix path-info -S before and after)
  • Ensured that relevant documentation is up to date
  • Fits CONTRIBUTING.md.

Sorry, something went wrong.

Thanks for contributing this service! I have a few suggestions which I hope are helpful.

Given this uses DynamicUser this option didn't seem very useful. I would recommend simply hard coding to /var/lib/mindustry.

Removed, thanks! Might make more sense if we also allow mods and maps to be included later on, but not currently as far as I can tell.

Agree, I have created an issue upstream at https://github.com/MindustryGame/wiki/issues/41. In the meantime I have appended the description string how to get available options.

Are there any variants of this package that make this option especially convenient?

Yes, there's the version whitelist override, which is a compile-time option

It'd be cool to have maps and mods options of type list of paths. Then we could package the best ones in an overlay.

But this would require separating the mods and maps directories from the stateDir (hoping the server doesn't somehow need write access to them)

Edit: shouldn't there be a meta.maintainers in the module too?

maps and mods would be awesome. Might make more sense in a separate PR though, as I have no idea how the server behaves there yet.
meta.maintainers thanks, added.

I am no longer hosting a Mindustry server, if anyone wants to pick this one up this please feel free to do so.
