Vladimir Timofeenko ae8bd1d85b nix: implement flake
This commit introduces the ability to install Docspell from a Nix flake.
There are no major changes to the logic of the previous modules outside of
organizing them in a flake and adding a simple check script.

Nix

Install via Nix

Docspell can be installed via the nix package manager, which is available for Linux and OSX. Docspell is currently not part of the nixpkgs collection, but you can use the flake from this repository.

Upgrading

Since downgrading is not supported, it is recommended to backup your database before upgrading. Should something not work as expected, restore the database backup and go back to the previous version.

Docspell on NixOS

If you are running NixOS, there is a module definition for installing Docspell as a service using systemd.

There are the following modules provided:

  • restserver
  • joex
# flake.nix
inputs.docspell.url = "github:eikek/docspell?dir=nix/";

# in modules
imports = [ 
      docspell.nixosModules.default
]

services.docspell-joex = { ...  }
services.docspell-restserver = { ...  }

Please see the nix/modules/server.nix and nix/modules/joex.nix files for the set of options. The nixos options are modeled after the default configuration file.

The modules files are only applicable to the newest version of Docspell. If you really need an older version, checkout the appropriate commit.

NixOS Example

This is a example system configuration that installs docspell with a postgres database. This snippet can be used to create a vm (using nixos-rebuild build-vm as shown above) or a container, for example.

# flake.nix
inputs.docspell.url = "github:eikek/docspell?dir=nix/";

# module.nix
{ config, pkgs, docspell, ... }:
{
  imports = docspell.nixosModules.default;

  ##### just for the example…
  users.users.root = {
    password = "root";
  };
  #####

  # install docspell-joex and enable the systemd service
  services.docspell-joex = {
    enable = true;
    base-url = "http://localhost:7878";
    bind = {
      address = "0.0.0.0";
      port = 7878;
    };
    scheduler = {
      pool-size = 1;
    };
    jdbc = {
      url = "jdbc:postgresql://localhost:5432/docspell";
      user = "docspell";
      password = "docspell";
    };
  };

  # install docspell-restserver and enable the systemd service
  services.docspell-restserver = {
    enable = true;
    base-url = "http://localhost:7880";
    bind = {
      address = "0.0.0.0";
      port = 7880;
    };
    auth = {
      server-secret = "b64:EirgaudMyNvWg4TvxVGxTu-fgtrto4ETz--Hk9Pv2o4=";
    };
    backend = {
      signup = {
        mode = "invite";
        new-invite-password = "dsinvite2";
        invite-time = "30 days";
      };
      jdbc = {
        url = "jdbc:postgresql://localhost:5432/docspell";
        user = "docspell";
        password = "docspell";
      };
    };
  };
