About this flake

This Nix flake packages Cryptpad, a collaborative office suite that is end-to-end encrypted and open-source.

Usage

With this flake you can deploy Cryptpad on NixOS. You can use the cryptpad module available in .#nixosModules.

Using flakes

Add from GitHub

{
  description = "Nix flake for my infrastructure";

  inputs = {
    nixpkgs = {
      url = "github:nixos/nixpkgs/nixos-23.11";
    };

    cryptpad = {
      url = "github:michaelshmitty/cryptpad-flake";
      inputs = {
        nixpkgs.follows = "nixpkgs";
      };
    };
  };

  outputs = { self, nixpkgs, cryptpad }@inputs: {
    nixosConfigurations.myhostname = nixpkgs.lib.nixosSystem {
      system = "x86_64-linux";
      modules = [
        ({ pkgs, ... }: {
          nixpkgs.overlays = [ inputs.cryptpad.overlays.default ];
        })
        inputs.cryptpad.nixosModules.cryptpad
        ./configuration.nix
      ];
    };
  };
}

Add from FlakeHub

Add the cryptpad flake to your flake.nix:

{
  inputs.cryptpad.url = "https://flakehub.com/f/michaelshmitty/cryptpad/*.tar.gz";

  outputs = { self, cryptpad }: {
    # Use in your outputs
  };
}

Configure

Now that you have the module available, configuration is straightforward. See example configuration.nix:

{ pkgs, lib, config, ... }:

{
  services.cryptpad = {
    enable = true;
    configureNginx = true;
    settings = {
      httpUnsafeOrigin = "https://cryptpad.example.com";
      httpSafeOrigin = "https://cryptpad-ui.example.com";

      # Add this after you've signed up in your Cryptpad instance and copy your public key:
      adminKeys = [ "[user@cryptpad.example.com/Jil1apEPZ40j5M8nsjO1-deadbeefHkt+QExscMzKhs=]" ];
    };
  };
}

Deploy and check your Cryptpad setup at https://<domain>/checkup

Run tests

This flake contains a simple integration test that will spin up a server NixOS container that will build and run Cryptpad and Nginx. And a client NixOS container that will test connectivity to the Cryptpad instance.

Execute nix flake check in this repository to run the integration test.

Adding Cryptpad to nixpkgs

There is an active, open PR to add Cryptpad back to nixpkgs. I am contributing my work on this flake into that PR.
