# Jellyfin
## Overview
Jellyfin is a free, open-source media server. It organizes your movies, shows, music and books and streams them to web, mobile and TV clients. In this setup Sonarr and Radarr fill the library; Jellyfin just reads it.
## Project Details
- **Project Repository:** [https://jellyfin.org/](https://jellyfin.org/) ([Docs](https://jellyfin.org/docs/))
- **Container Image:** [jellyfin/jellyfin](https://hub.docker.com/r/jellyfin/jellyfin)
- **Reverse Proxy Port:** `8096`
## Getting Started
### Prepare the shared media folder (once per host)
All media apps run as user `1000` and share `/data/media`. If Docker creates the folder itself it's owned by root, and the apps fail with *"Folder '/media/' is not writable by user 'hotio'"*. Create it with the right owner before first start:
```bash
sudo mkdir -p /data/media/{downloads/prowlarr,movies,shows,music,books}
sudo chown -R 1000:1000 /data/media
sudo chmod -R u+rwX,g+rwX /data/media
```
Check with `ls -ln /data/media` — the owner should be `1000 1000`.
Open http://localhost:8096 in your browser and complete the setup wizard:
1. **Create your admin account**
2. **Add media libraries** — point each one at the matching container folder:
| Library type | Folder |
|---|---|
| Movies | `/movies` |
| Shows | `/shows` |
| Music | `/music` |
| Books | `/books` |
3. Finish the wizard. Jellyfin scans the folders and pulls metadata.
For Jellyseerr, create an API key under **Dashboard → API Keys**.
## Environment Variable Notes
| Variable | Description |
|---|---|
| `JELLYFIN_IMAGE` | Container image (default: `jellyfin/jellyfin:latest`) |
| `JELLYFIN_RESTART` | Restart policy (default: `unless-stopped`) |
| `JELLYFIN_PORT` | Published port for the web UI (default: `8096`) |
| `JELLYFIN_URL` | Public URL clients use to reach the server (default: `http://localhost:8096`) — set this to your reverse proxy URL |
| `JELLYFIN_MEDIA` | Shared media root on the host (default: `/data/media`) — the same folder qBittorrent, Sonarr, Radarr and Bazarr use |
| `VOL_PATH` | Base path for persistent data volumes (default: `/data`) |
## Volume Notes
| Volume | Purpose |
|---|---|
| `${VOL_PATH:-/data}/jellyfin/config` | Configuration, database and metadata |
| `${VOL_PATH:-/data}/jellyfin/cache` | Transcode and image cache |
| `${JELLYFIN_MEDIA:-/data/media}/movies` → `/movies` | Movies (Radarr root folder `/media/movies`) |
| `${JELLYFIN_MEDIA:-/data/media}/shows` → `/shows` | TV shows (Sonarr root folder `/media/shows`) |
| `${JELLYFIN_MEDIA:-/data/media}/music` → `/music` | Music |
| `${JELLYFIN_MEDIA:-/data/media}/books` → `/books` | Books |
Jellyfin mounts only the library subfolders, not `/data/media/downloads`, so half-finished downloads never show up in the library.
## Network Notes
Requires an external `proxy` network. Create it once with:
```bash
docker network create proxy
```
Jellyseerr reaches Jellyfin at `http://jellyfin:8096` over the `proxy` network.
## Docker Run
```bash
docker run -d \
--name=jellyfin \
-e JELLYFIN_PublishedServerUrl=http://localhost:8096 \
-p 8096:8096 \
-v ${VOL_PATH:-/data}/jellyfin/cache:/cache \
-v ${VOL_PATH:-/data}/jellyfin/config:/config \
-v ${JELLYFIN_MEDIA:-/data/media}/books:/books \
-v ${JELLYFIN_MEDIA:-/data/media}/movies:/movies \
-v ${JELLYFIN_MEDIA:-/data/media}/music:/music \
-v ${JELLYFIN_MEDIA:-/data/media}/shows:/shows \
--network proxy \
--restart unless-stopped \
jellyfin/jellyfin:latest
```
## Additional Notes / Gotchas
- **Only port 8096 is published.** HTTPS (8920) is handled by Nginx Proxy Manager. Local network auto-discovery (UDP 1900/7359) won't work through the bridge network, so add the server to clients by URL.
- **Photos** are left out on purpose — use the Immich stack for photo libraries.
- **Hardware transcoding** needs the GPU passed into the container (e.g. `devices: [/dev/dri:/dev/dri]` for Intel/AMD). It's not included by default.
## Dockhand Stack, Deploy from Git
- **Cookbooks Repository**
- **stackname:** jellyfin
- **Compose file path:** jellyfin/compose.yaml
- **Additional env file (optional):** jellyfin/sample.env
Load `jellyfin/sample.env` into the Environment variables in Dockhand, then create the Stack.
