# Immich NixOS Module Implementation Plan
> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
>
> **Note on nature:** Task 1 is repo work verifiable with `nix build` (no runtime tests exist for declarative config). Tasks 26 are a **manual migration runbook executed on jupiter by the operator** — they are destructive and cannot be run from the dev machine (mibook). Do not attempt to automate or execute Tasks 26 from an agent session; present them for the operator to run and confirm.
**Goal:** Replace jupiter's docker-compose Immich with the native `services.immich` NixOS module, preserving all data (albums, faces, shares, library).
**Architecture:** A standard `my.profiles.immich` module wraps `services.immich` (native Postgres+VectorChord over unix socket, Redis, server, machine-learning). Media stays at the default local `/var/lib/immich`. The existing docker Postgres dump is restored same-version (2.7.5 → 2.7.5, no schema/vector migration). GPU is exposed for VAAPI/QSV transcoding.
**Tech Stack:** NixOS (flake-parts), `services.immich` from nixpkgs 25.11, PostgreSQL, Intel QSV/VAAPI, docker (source only).
## Global Constraints
- Machine: **jupiter** only. Do not enable on mibook.
- Immich version: source docker == target nixpkgs == **2.7.5** (stable). No `package` override. Do NOT bump nixpkgs Immich during this work.
- Media location: default `/var/lib/immich` (local disk). Do not point at the NAS.
- Database: local PostgreSQL over **unix socket + peer auth** — no password, no sops secret.
- HW accel: **video transcoding only**. ML stays on CPU (`machine-learning.enable = true`, no OpenVINO).
- Access: LAN + VPN, `openFirewall = true`, port **2283**. No reverse proxy/TLS.
- Rebuild command: `sudo nixos-rebuild switch --flake '.#jupiter'`.
- Build-check command: `nix build '.#nixosConfigurations.jupiter.config.system.build.toplevel'`.
- Format Nix with `nixfmt-rfc-style` before committing.
- Do not delete docker DB or upload data until Task 6 sign-off.
---
## File Structure
- **Create** `modules/environments/immich/default.nix` — the `my.profiles.immich` module (single responsibility: declare Immich).
- **Modify** `modules/environments/default.nix` — add `./environments/immich` to the import list.
- **Modify** `machines/jupiter/environments.nix` — set `immich.enable = true`.
No other files change. The DB/media migration touches only runtime state on jupiter, not the repo.
---
### Task 1: Author the `immich` profile module
**Files:**
- Create: `modules/environments/immich/default.nix`
- Modify: `modules/environments/default.nix` (import list)
- Modify: `machines/jupiter/environments.nix` (`my.profiles.immich.enable`)
**Interfaces:**
- Produces: NixOS option `my.profiles.immich.enable` (bool). When true, configures `services.immich`, adds `immich` user to `video`/`render` groups, and appends an entry to `my.homepage.services`.
- Consumes: existing `my.homepage.services` aggregator; `config.networking.hostName`.
- [ ] **Step 1: Read a reference module to match repo style**
Read `modules/environments/jellyfin/default.nix` (same shape: `cfg`, `hostName`, `port`, `mkIf`, `my.homepage.services`). Match its formatting and header-comment convention.
- [ ] **Step 2: Create the module file**
Create `modules/environments/immich/default.nix`:
```nix
# Immich self-hosted photo & video server
{
config,
lib,
pkgs,
...
}:
let
cfg = config.my.profiles.immich;
hostName = config.networking.hostName;
port = 2283;
in
{
options.my.profiles.immich = with lib; {
enable = mkEnableOption "Immich photo server";
};
config = lib.mkIf cfg.enable {
services.immich = {
enable = true;
host = "0.0.0.0";
inherit port;
openFirewall = true;
mediaLocation = "/var/lib/immich";
machine-learning.enable = true;
accelerationDevices = [ "/dev/dri/renderD128" ];
settings.server.externalDomain = "http://${hostName}:${toString port}";
};
# The native module does not add GPU groups; required for VAAPI/QSV transcoding.
users.users.immich.extraGroups = [
"video"
"render"
];
my.homepage.services = [
{
group = "Media";
name = "Immich";
description = "Photo & video server";
href = "http://${hostName}:${toString port}";
icon = "immich.png";
}
];
};
}
```
- [ ] **Step 3: Register the module in the environments import list**
Open `modules/environments/default.nix` and add `./environments/immich` (or `./immich`, matching the exact relative style already used in that file — check how `jellyfin` is listed and mirror it).
- [ ] **Step 4: Enable it on jupiter**
In `machines/jupiter/environments.nix`, inside the `my.profiles = { ... }` block, add:
```nix
immich.enable = true;
```
- [ ] **Step 5: Format**
Run: `nixfmt-rfc-style modules/environments/immich/default.nix`
- [ ] **Step 6: Build-check (this is the "test")**
Run: `nix build '.#nixosConfigurations.jupiter.config.system.build.toplevel'`
Expected: builds successfully. If it fails on an unknown option (e.g. `accelerationDevices`, `settings.server.externalDomain`), reconcile against the module at `$(nix eval --raw '.#nixosConfigurations.jupiter.pkgs.path')/nixos/modules/services/web-apps/immich.nix` and fix.
- [ ] **Step 7: Confirm the option evaluates on**
Run: `nix eval '.#nixosConfigurations.jupiter.config.services.immich.enable'`
Expected: `true`
- [ ] **Step 8: Commit**
```bash
git add modules/environments/immich/default.nix modules/environments/default.nix machines/jupiter/environments.nix
git commit -m "feat(jupiter): add native Immich profile module"
```
---
### Task 2: Pre-flight & backup on jupiter (operator-run)
**Files:** none (runtime state on jupiter). Run all commands on jupiter.
**Interfaces:**
- Produces: `immich-db.sql` dump file and a known-good copy/snapshot of the docker upload folder; recorded `UPLOAD_LOCATION` path and DB container name.
- [ ] **Step 1: Record docker facts**
From the docker-compose dir on jupiter, note `UPLOAD_LOCATION`, the DB service/container name, and `POSTGRES_USER`/`POSTGRES_DB` from `.env`/compose. Confirm server version is **2.7.5** (web UI footer or `docker exec <server> immich --version`). If it is not 2.7.5, STOP — this plan assumes a same-version restore.
- [ ] **Step 2: Stop the docker stack (DB may stay up for the dump)**
Run: `docker compose stop immich-server immich-machine-learning` (leave the DB container running).
- [ ] **Step 3: Dump the database**
Run: `docker exec -t <db-container> pg_dumpall --clean --if-exists --username=<POSTGRES_USER> > ~/immich-db.sql`
Expected: a non-trivial `immich-db.sql` (check it is not near-empty: `wc -l ~/immich-db.sql`).
- [ ] **Step 4: Stop the DB and record the media size**
Run: `docker compose down` then `du -sh <UPLOAD_LOCATION>` and note the size. Do NOT copy yet. Do NOT delete anything.
---
### Task 3: First switch — let the module create empty state (operator-run)
**Files:** none at runtime (repo change already committed in Task 1). Run on jupiter after pulling the committed branch.
**Interfaces:**
- Consumes: `immich-db.sql`, `UPLOAD_LOCATION` from Task 2.
- Produces: an `immich` system user, an empty `immich` Postgres DB + role, and `/var/lib/immich` created with correct ownership, with services then stopped.
- [ ] **Step 1: Deploy the config**
On jupiter, check out the branch containing Task 1's commit and run:
`sudo nixos-rebuild switch --flake '.#jupiter'`
Expected: `immich-server`, `immich-machine-learning`, postgres, and redis units come up; UI reachable at `http://jupiter:2283` showing a fresh/empty instance.
- [ ] **Step 2: Stop immich so data can be swapped underneath**
Run: `sudo systemctl stop immich-server immich-machine-learning`
Expected: both inactive. PostgreSQL and Redis stay running.
- [ ] **Step 3: Verify the DB and user exist**
Run: `sudo -u postgres psql -c '\l' | grep immich` and `sudo -u postgres psql -c '\du' | grep immich`
Expected: an `immich` database and `immich` role are present.
---
### Task 4: Restore database and media (operator-run, destructive)
**Files:** none in repo. Run on jupiter. This overwrites the freshly-created empty DB.
**Interfaces:**
- Consumes: `immich-db.sql`, `<UPLOAD_LOCATION>`, the running NixOS PostgreSQL.
- Produces: the migrated DB and populated `/var/lib/immich`.
- [ ] **Step 1: Restore the dump into the NixOS Postgres**
`pg_dumpall` output includes role/DB creation. Load it as the `postgres` superuser over the unix socket:
Run: `sudo -u postgres psql -f ~/immich-db.sql`
Expected: completes without fatal errors. Harmless "role already exists"/"database already exists" notices are OK because of `--clean --if-exists`. If the immich DB ends up owned by the wrong role, reassign: `sudo -u postgres psql -c 'ALTER DATABASE immich OWNER TO immich;'`.
- [ ] **Step 2: Sanity-check the restored data**
Run: `sudo -u postgres psql -d immich -c 'SELECT count(*) FROM assets;'`
Expected: a count matching your library size (non-zero). If the table name differs by version, list tables with `\dt` and check an obviously-populated one.
- [ ] **Step 3: Move the media into the default location**
Immich's upload folder holds subdirs `library/ upload/ thumbs/ encoded-video/ profile/ backups/`. Move (not copy, if same filesystem) the contents of `<UPLOAD_LOCATION>` into `/var/lib/immich`:
Run: `sudo rsync -aHAX --info=progress2 <UPLOAD_LOCATION>/ /var/lib/immich/`
(Use `rsync` — safe if partially interrupted. Keep the source until Task 6 sign-off.)
- [ ] **Step 4: Fix ownership**
Run: `sudo chown -R immich:immich /var/lib/immich`
Expected: everything under `/var/lib/immich` owned by `immich`.
---
### Task 5: Start and verify (operator-run)
**Files:** none. Run on jupiter.
**Interfaces:**
- Consumes: migrated DB + media from Task 4.
- Produces: a running, verified native Immich.
- [ ] **Step 1: Start the server and watch logs**
Run: `sudo systemctl start immich-server && journalctl -u immich-server -f`
Expected: it connects to the DB, runs same-version startup checks (no destructive migration since 2.7.5==2.7.5), and reports listening on 2283. Leave the follow running through the next step.
- [ ] **Step 2: Start machine-learning**
Run: `sudo systemctl start immich-machine-learning`
Expected: active, no crash loop in `journalctl -u immich-machine-learning`.
- [ ] **Step 3: Functional spot-check in the web UI**
At `http://jupiter:2283`: log in with an existing account; confirm the timeline loads; open an **album**; open the **People/faces** view; open a **shared link**; open one photo so a **thumbnail and its full original both load** (this proves DB↔file paths align after the media move).
Expected: all present, images render.
- [ ] **Step 4: Confirm homepage dashboard tile**
Open the homepage dashboard; confirm the Immich tile appears under "Media" and links to `http://jupiter:2283`.
- [ ] **Step 5: Enable and verify hardware transcoding**
In Immich **Administration → Settings → Video Transcoding**, set hardware acceleration to **Quick Sync** (QSV) (or VAAPI). Trigger a transcode (upload/play a video that needs transcoding, or run the transcoding job). Then:
Run: `journalctl -u immich-server | grep -iE 'qsv|vaapi|hwaccel|transcode'`
Expected: log shows the hardware path in use, not a CPU-fallback error. Confirm `/dev/dri/renderD128` is accessible to the service (the `video`/`render` groups + `accelerationDevices` from Task 1 handle this).
---
### Task 6: Sign-off and cleanup (operator-run)
**Files:** none in repo. Merge the branch; then, only after a confidence window, remove docker.
**Interfaces:**
- Consumes: a verified running instance (Task 5).
- [ ] **Step 1: Merge the feature branch**
Open a PR from `feat/immich-nixos-module` into `main` and merge it (repo convention: PRs via the Gitea remote).
- [ ] **Step 2: Confidence window**
Use Immich normally for a few days. Keep the docker `<UPLOAD_LOCATION>` source copy and `~/immich-db.sql` untouched as the rollback path.
- [ ] **Step 3: Rollback (only if needed, before cleanup)**
If something is wrong: `sudo systemctl stop immich-server immich-machine-learning`, set `immich.enable = false` (or check out the pre-migration commit), `sudo nixos-rebuild switch --flake '.#jupiter'`, then `docker compose up -d` in the old stack. Original docker DB + upload folder are intact until Step 4.
- [ ] **Step 4: Cleanup (after sign-off)**
Remove the docker Immich stack (`docker compose down --rmi all --volumes` in the old dir if the DB volume is dedicated — verify first), delete the now-duplicated `<UPLOAD_LOCATION>` source, and remove `~/immich-db.sql`. Optionally disable the `docker` profile on jupiter if Immich was its only consumer (check other services first — jupiter's `docker.enable` may still be needed).

## Self-Review
**Spec coverage:**
- Native `services.immich` → Task 1. ✓
- Version target 2.7.5==stable, no override → Global Constraints + Task 2 Step 1. ✓
- Media at default `/var/lib/immich` → Task 1 + Task 4 Step 3. ✓
- DB migrate keep-everything → Tasks 24. ✓
- HW transcoding only → Task 1 (`accelerationDevices`, groups) + Task 5 Step 5. ✓
- LAN+VPN, port 2283, openFirewall, homepage tile → Task 1 + Task 5 Steps 34. ✓
- Rollback path → Task 6 Step 3. ✓
- Deferred (OpenVINO/NAS/proxy) → correctly absent. ✓
**Placeholder scan:** No TBD/TODO; every command is concrete. Placeholders like `<db-container>`, `<UPLOAD_LOCATION>`, `<POSTGRES_USER>` are runtime values the operator reads in Task 2 Step 1 — intentional, not gaps.
**Type consistency:** Option name `my.profiles.immich.enable` and path `/var/lib/immich` used consistently across all tasks. Media subfolder list matches between Task 4 Step 3 and the spec.

# Immich: Docker → NixOS module migration
**Date:** 2026-08-05
**Machine:** jupiter (home server, Intel iGPU)
**Status:** Design approved, pending implementation plan
## Goal
Replace the existing docker-compose Immich deployment on jupiter with the
native `services.immich` NixOS module, wrapped in the repo's standard
`my.profiles.*` pattern. Preserve all existing data (albums, faces, shared
links, metadata) and photo/video library.
## Decisions
| Topic | Decision |
|-------|----------|
| Approach | Native `services.immich` (nixpkgs), not `oci-containers` |
| Version target | **Resolved: docker runs 2.7.5 == stable nixpkgs 2.7.5.** Use the stable module as-is; no `package` override. Same-version restore, no forward schema migration |
| Media location | Default local path `/var/lib/immich`. NAS deferred to a future read-only external library |
| Database | Migrate via dump/restore — keep everything |
| HW acceleration | Video transcoding only (VAAPI/QSV via existing Intel graphics stack). ML on CPU |
| Access | LAN + VPN only: open port 2283, register on homepage dashboard. No reverse proxy/TLS |
### Deliberately deferred (YAGNI)
- OpenVINO ML acceleration
- NAS-backed external library
- Reverse proxy / TLS / public hostname
## Part 1 — The module
New file `modules/environments/immich/default.nix` following the profile
pattern; add `./environments/immich` to `modules/environments/default.nix`;
enable `my.profiles.immich.enable = true` in
`machines/jupiter/environments.nix`.
```nix
{ config, lib, pkgs, ... }:
let
cfg = config.my.profiles.immich;
hostName = config.networking.hostName;
port = 2283;
in {
options.my.profiles.immich.enable = lib.mkEnableOption "Immich photo server";
config = lib.mkIf cfg.enable {
services.immich = {
enable = true;
# package = pkgs.unstable.immich; # only if docker :release is > 2.7.5
host = "0.0.0.0";
inherit port;
openFirewall = true;
mediaLocation = "/var/lib/immich";
machine-learning.enable = true;
accelerationDevices = [ "/dev/dri/renderD128" ];
settings.server.externalDomain = "http://${hostName}:${toString port}";
};
# native module does not add GPU groups; needed for VAAPI/QSV transcoding
users.users.immich.extraGroups = [ "video" "render" ];
my.homepage.services = [{
group = "Media";
name = "Immich";
description = "Photo & video server";
href = "http://${hostName}:${toString port}";
icon = "immich.png";
}];
};
}
```
**Provided for free by the native module:** local PostgreSQL with the required
vector extension over a **unix socket + peer auth** (so no DB password / sops
secret needed), Redis, `immich-server` and `immich-machine-learning` systemd
units, the `immich` system user, and `mediaLocation` created via tmpfiles.
**Transcoding is two parts:** (a) NixOS exposes the GPU device + `video`/`render`
groups (above); (b) the hwaccel backend (QSV/VAAPI) is chosen in Immich's
**admin → video transcoding** settings after cutover — a UI toggle, not Nix.
## Part 2 — Migration runbook (on jupiter)
### Pre-flight (hard blocker)
1. Get running docker Immich version (`docker exec <server> immich --version` or web UI footer).
2. **Resolved 2026-08-05: running version is 2.7.5, equal to stable nixpkgs.**
Use the stable module as-is (no `package` override). Kept for reference:
- running ≤ 2.7.5 → stable module as-is ← **this case**
- 2.7.63.0.3 → set `package = pkgs.unstable.immich`
- `> 3.0.3` → bump nixpkgs first; **stop and re-plan**
3. Record docker `UPLOAD_LOCATION` and DB container name/credentials.
### Backup (before touching anything)
4. `docker compose down` (DB may stay up for the dump).
5. Dump DB: `docker exec -t <db> pg_dumpall --clean --if-exists --username=postgres > immich-db.sql`
6. Verify upload folder intact; note size (no copy yet).
### Cutover
7. Add the module to jupiter's `environments.nix` (leave `database.createDB` default).
8. `sudo nixos-rebuild switch --flake '.#jupiter'` → creates user, empty DB + role, `mediaLocation`. Then `systemctl stop immich-server immich-machine-learning`.
9. Restore the DB into the NixOS Postgres (drop the freshly-created empty `immich` DB, load `immich-db.sql`) per Immich's restore docs.
10. Move media into `/var/lib/immich` (subfolders `library/`, `upload/`, `thumbs/`, `encoded-video/`, `profile/`); `chown -R immich:immich /var/lib/immich`.
11. `systemctl start immich-server`; it runs schema migrations forward. Watch `journalctl -u immich-server -f`.
### Verify
12. UI at `http://jupiter:2283` loads; log in; spot-check albums, faces, a shared link, and that thumbnails/originals actually load.
13. Homepage tile works.
14. Enable QSV/VAAPI in admin settings; transcode one video; confirm `journalctl` shows the hw path, not a CPU fallback error.
### Rollback
Before deleting any docker data: `systemctl stop immich-*`, disable the profile,
`nixos-rebuild switch`, `docker compose up -d`. Original docker DB + upload
folder remain untouched until explicitly removed after a few days of confidence.
## Known risk — RESOLVED
The main risk was step 9 crossing the **pgvecto.rs → VectorChord** vector-extension
boundary. With source and target both at **2.7.5**, both use VectorChord — no
boundary crossing and no forward schema migration. The restore is a same-version
dump/load. Residual risk is limited to routine dump/restore mechanics
(roles, extension availability in the NixOS Postgres, ownership on restore).
