hortusfox-web-nixos

A Nix flake that packages HortusFox — a self-hosted, PHP/Laravel-style collaborative plant-management app — from source, and provides a NixOS module to run it as a full service: mariadb + phpfpm + nginx or caddy + ACME + the app's own cron endpoints on systemd timers.

There is no HortusFox source code in this repo — the app itself is fetched from upstream at build time via php.buildComposerProject. This repo is purely packaging and deployment glue: a package.nix derivation and a services.hortusfox-web NixOS module that wires the built package into a real, stateful host.

Flake outputs

Output	What it is
packages.hortusfox-web / packages.default	The built HortusFox package.
overlays.default	Adds hortusfox-web to pkgs.
nixosModules.default	The services.hortusfox-web module.
devShells.default	PHP (matching the module's build) + extensions, composer, just, nix-output-monitor.
checks.<system>.build	Builds the package.
checks.<system>.vm-test / vm-test-caddy	Boots a full nixosTest VM per proxy backend and exercises a real login.
nixosConfigurations.test	A throwaway VM (tests/) for manual poking — not meant for real deployments.

Usage

{
  inputs.hortusfox-web.url = "github:<you>/hortusfox-web-nixos";

  outputs = { self, nixpkgs, hortusfox-web, ... }: {
    nixosConfigurations.myhost = nixpkgs.lib.nixosSystem {
      system = "x86_64-linux";
      modules = [
        hortusfox-web.nixosModules.default
        {
          services.hortusfox-web = {
            enable = true;
            domain = "plants.example.com";
            adminAccount.passwordFile = "/run/secrets/hortusfox-admin-password";
            adminAccount.email = "you@example.com";
            secretFile = "/run/secrets/hortusfox.env"; # APP_KEY, SMTP_PASSWORD, ...
          };

          # proxy.ssl defaults to true (forceSSL + ACME); the host config
          # must then set one of these globally:
          security.acme = { acceptTerms = true; defaults.email = "you@example.com"; };
          # or, if services.hortusfox-web.proxy.server = "caddy":
          # services.caddy.email = "you@example.com";
        }
      ];
    };
  };
}

services.hortusfox-web options

Option	Type	Default	Description
enable	bool	false	Enable the service.
domain	string	"localhost"	FQDN served over HTTPS; used for the nginx/caddy vhost and ACME.
port	null or port	null	Appended to the app's own canonical URL (APP_URL) and, when set, overrides the SERVER_PORT fastcgi param/env seen by PHP. Needed whenever the proxy is only reachable through a forwarded/non-standard port (e.g. the test VM's QEMU hostfwd) — Asatru's own url()/asset() helpers build every absolute URL from the request's SERVER_PORT, not from APP_URL, so without this every generated asset/redirect URL silently drops the real external port. Does not change what port nginx/caddy actually listen on.
package	package	built from package.nix	The HortusFox package to deploy.
proxy.server	"nginx" | "caddy"	"nginx"	Reverse proxy/webserver fronting phpfpm.
proxy.ssl	bool	true	Force HTTPS + request an ACME cert for the vhost. Set false for local/test deployments with no real domain or internet access to reach Let's Encrypt.
phpPackage	package	pkgs.php83	Base PHP the phpfpm environment is built from (extensions are added automatically).
user / group	string	"hortusfox"	System user/group the app and its phpfpm pool run as.
timezone	string	"UTC"	App timezone (APP_TIMEZONE).
database.name	string	"hortusfox"	MariaDB database name.
secretFile	null or path	null	File of KEY=VALUE lines (APP_KEY, SMTP_PASSWORD, API keys, ...) appended verbatim onto the generated .env at runtime — not parsed, so it can carry arbitrary keys. Keep it out of the Nix store in production (agenix/sops-nix); a store path is fine for throwaway test configs.
adminAccount.passwordFile	null or path	null	Plaintext password file for a seeded initial admin account. HortusFox has no CLI/seed hook of its own and its only "create user" flow lives behind the admin panel, so without this a fresh deployment has no way to log in at all. Only takes effect on first boot; changing it later has no effect on an existing account.
adminAccount.username	string	"admin"	Name for the seeded admin account — purely a display name, since HortusFox logs in by email rather than this field.
adminAccount.email	string	"admin@${domain}"	Email for the seeded admin account. The default is just a guess at a real mailbox — set it to an address you actually control if you intend to use HortusFox's "Restore password" flow, which emails it.
settings	attrs of str/int/bool	{ }	Extra/overriding .env entries, merged over the module's generated defaults (settings always wins). Note php asatru (used for migrations) only runs when APP_DEBUG is true, so migrations silently no-op unless it's set here or via secretFile.
smtp.host	string	""	SMTP server host.
smtp.port	port	587	SMTP server port.
smtp.username	string	""	SMTP username.
smtp.fromName	string	"HortusFox"	SMTP from-name.
smtp.fromAddress	string	"hortusfox@localhost"	SMTP from-address.
smtp.encryption	"tls" | "ssl" | ""	"tls"	SMTP transport encryption.

SMTP password isn't a module option — set SMTP_PASSWORD via secretFile instead, alongside APP_KEY.

What the module actually does

• Copies the read-only Nix store package into a writable runtime tree (/run/hortusfox/www) on every boot, then symlinks a handful of subdirectories (cache, app/logs, public/img, public/attachments, public/backup, public/themes) into persistent state under /var/lib/hortusfox, seeding them from the package's own shipped defaults first so nothing gets silently deleted on first boot.
• Renders .env from the module's curated + mirrored-upstream defaults, settings (always wins), and secretFile (appended verbatim).
• Runs php asatru migrate:fresh on first boot (schema only) and migrate:upgrade on every boot after, guarded by a stateDir/.installed marker so a destructive fresh migration never runs twice.
• Optionally seeds a single admin account directly into the database on first boot, since HortusFox has no other way to create the very first user.
• Drives HortusFox's own HTTP cron endpoints (task/calendar reminders, auto-backup) via systemd timers rather than an in-process scheduler.

See nixos-module/default.nix and CLAUDE.md for the full reasoning and the gotchas each of these design choices worked around (several were real, previously-shipped bugs).

Local development / testing

nix develop            # dev shell: PHP+extensions, composer, just, nix-output-monitor
just build-vm          # build the throwaway test VM (nixosConfigurations.test)
just boot-vm           # boot it in-terminal (QEMU, serial console); http://127.0.0.1:8080
just clean             # tear down local VM artifacts (this project's own qemu instance + build outputs)

nix flake check        # evaluate all outputs; builds the package + boots both proxy-backend VM tests
nix flake check -L     # same, with full build/VM logs streamed (slow: boots two real VMs)

The test VM's seeded admin account logs in with the password in tests/hortusfox_web_test_password (currently password) — see tests/default.nix for its full config.
