# Jellyfin with Tailscale Integration


![Jellyfin with Tailscale](https://jellyfin.org/images/logo.svg "Jellyfin")


This project sets up a Jellyfin instance with Tailscale VPN integration using Docker Compose. It creates a secure, private network connection for your Jellyfin instance using Tailscale.

## Prerequisites

- Docker and Docker Compose installed on your system
- A Tailscale account and auth key (get one from https://login.tailscale.com/admin/authkeys)
- Basic understanding of Docker and networking concepts

## Project Structure
```
ts-jellyfin/
├── docker-compose.yml
├── tailscale/
│   ├── tailscale-data/  # Persistent Tailscale state
│   └── config/         # Tailscale configuration files
└── jellyfin/
    └── config/         # Jellyfin configuration files
    └── cache/         # Jellyfin cache files
    └── media/         # Jellyfin media files
```

## Setup Instructions

1. **Clone the Repository**
   ```bash
   git clone https://gitea.damconsulting.llc/DAM/ts-jellyfin/
   cd ts-jellyfin
   ```
2. Create Required Directories
    ```bash
    mkdir -p tailscale/tailscale-data jellyfin/config jellyfin/cache jellyfin/media
    ```
3. Configure Tailscale
    - Replace `{{YOUR_TAILSCALE_AUTHKEY}}` in the docker-compose.yml with your actual Tailscale auth key
    - Optionally, update the file in `tailscale/config/serve.json` if you need specific Tailscale serve configurations
        - CAUTION: Changing `"${TS_CERT_DOMAIN}:443": false` to `true` will expose the service to the internet

4. Start the Services
    ```bash
    docker compose up -d
    ```

5. Wait for Certificate to propagate [~2m] 

6. Login with and create admin account

## Services

### jellyfin-ts (Tailscale)

- Runs Tailscale VPN client
- Image: tailscale/tailscale:latest
- Container name: jellyfin-ts
- Hostname: jellyfin
- Requires NET_ADMIN and SYS_MODULE capabilities
- Persists state in ./tailscale/tailscale-data
- Uses configuration from ./tailscale/config

### jellyfin

- Depends on jellyfin-ts service

## Usage

- After starting the services your service should be available via tailnet at `https://jellyfin.{{YOUR_TAILNET_DOMAIN}}.ts.net` ie `https://jellyfin.tail12345.ts.net/`
- To manually get the Tailscale IP/hostname of your container:
    ```bash
    docker logs jellyfin-ts
    ```
    Look for the Tailscale IP address in the logs.

## Optional Features

- Uncomment the Docker socket volume mapping in the service to enable Docker integrations:
    ```yaml
    - /var/run/docker.sock:/var/run/docker.sock
    ```
- Uncomment and adjust the ports mapping if you need direct access (without Tailscale):
    ```yaml
    ports:
    - 8096:8096
    ```
- Stopping the Services
    ```bash
    docker compose down
    ```

## Troubleshooting
- Check container logs:
    ```bash
    docker logs jellyfin-ts
    docker logs jellyfin
    ```
- Ensure your Tailscale auth key is valid and not expired
- Verify the configuration files have proper permissions
- Make sure required directories exist before starting
## Notes
- The Jellyfin service uses the Tailscale service's network stack via network_mode: service:Jellyfin-ts
- Direct port mapping is disabled by default as Tailscale handles the networking
- Services restart automatically unless explicitly stopped
