# Docker Compose NAS
This project provides a comprehensive, self-hosted media and utility server setup using Docker Compose. It aims to replicate and enhance the functionality of a typical NAS using containerized applications on a standard Linux host.
The core idea is to manage media libraries (movies, TV shows, music), automate downloads securely, provide easy access via a dashboard, and enable remote access through Tailscale.

## Architecture Overview
This stack uses a combination of key services for routing, access, and security:
* **[Tailscale](https://tailscale.com):** Provides a secure overlay network (WireGuard-based VPN) connecting your devices. It allows access to the NAS services from anywhere without opening firewall ports and handles HTTPS termination via its built-in `tailscale serve` or `tailscale funnel` features. All other services run within Tailscale's network namespace.
* **[Traefik](https://traefik.io):** Acts as a reverse proxy *within* the Tailscale network. It discovers services via Docker labels and routes incoming requests (from Tailscale) to the appropriate container based on paths (e.g., `/sonarr`, `/radarr`).
* **[Authelia](https://www.authelia.com):** Serves as the authentication gateway. Traefik forwards requests to Authelia for verification. If a user isn't logged in, they are redirected to the Authelia portal (`/`). Once authenticated, Authelia sets a session cookie (stored in Redis), and Traefik allows access to the requested service.
## Features
This stack includes the following services, categorized for clarity:
**Core Infrastructure:**
* **Reverse Proxy:** [Traefik](https://traefik.io) - Manages internal routing and service discovery.
* **Secure Remote Access:** [Tailscale](https://tailscale.com) - Provides VPN access and HTTPS.
* **Authentication:** [Authelia](https://www.authelia.com) & [Redis](https://redis.io) - Single sign-on portal and session management.
* **Dashboard:** [Homepage](https://gethomepage.dev) - Centralized access point (at `/home`).
**Media Management (\*Arr Suite):**
* [Sonarr](https://sonarr.tv): TV show management.
* [Radarr](https://radarr.video): Movie management.
* [Lidarr](https://lidarr.audio) (Optional): Music management.
* [Bazarr](https://www.bazarr.media/): Subtitle management.
* [Prowlarr](https://github.com/Prowlarr/Prowlarr): Indexer management for *arr apps.
**Download Clients:**
* [qBittorrent](https://www.qbittorrent.org): Bittorrent client.
* [SABnzbd](https://sabnzbd.org/) (Optional): Usenet download client.
**Media Serving & Requests:**
* [Jellyfin](https://jellyfin.org): Media server for streaming.
* [Jellyseerr](https://github.com/FallenBagel/jellyseerr): Media request management.

## Required Setup Steps
These steps are **mandatory** for a working installation. Without properly completing these, the stack will not function correctly.
1. **⚠️ Required: System User Information**
- Set `USER_ID` and `GROUP_ID` in `.env` (run `id -u` and `id -g` to get yours)
- Incorrect values will cause permission errors with mounted volumes
2. **⚠️ Required: Directory Paths**
- Set `CONFIG_ROOT` (where service configurations will be stored)
- Set `DATA_ROOT` (where your media libraries will be stored)
- Set `DOWNLOAD_ROOT` (must be on same filesystem as DATA_ROOT for hardlinks)
3. **⚠️ Required: Tailscale Configuration**
- Create a Tailscale account at [tailscale.com](https://tailscale.com)
- Generate an Auth Key in the [Tailscale Admin Console](https://login.tailscale.com/admin/settings/keys)
- Set `TAILSCALE_AUTHKEY` in `.env`
- Set `TAILSCALE_TAILNET_DOMAIN` to your Tailnet domain (e.g., `your-name.ts.net`)
4. **⚠️ Required: Security Credentials**
- Generate four strong random secrets using `openssl rand -hex 32`:
```bash
echo "AUTHELIA_JWT_SECRET=$(openssl rand -hex 32)"
echo "AUTHELIA_SESSION_SECRET=$(openssl rand -hex 32)"
echo "AUTHELIA_STORAGE_ENCRYPTION_KEY=$(openssl rand -hex 32)"
echo "AUTHELIA_REDIS_PASSWORD=$(openssl rand -hex 32)"
```
- Add these to your `.env` file as shown
5. **⚠️ Required: Create Admin Password**
- Generate a password hash for Authelia:
```bash
docker run --rm authelia/authelia:latest authelia hash-password 'your_secure_password'
```
- Replace the example hash in `authelia/users_database.yml` with your generated hash
## Quick Start Guide

## Detailed Setup & Usage
### Authelia User Management
Authelia uses the `authelia/users_database.yml` file to manage users.
* **Setting the Initial Admin Password:**
1. As mentioned in the Quick Start, you **must** set a strong password for the default `admin` user.
2. Generate a hash using Docker (replace `'your_secure_password'`):
```bash
docker run --rm authelia/authelia:latest authelia hash-password 'your_secure_password'
```
3. Copy the **entire output hash** (starting with `$argon2id...`).
4. Open `authelia/users_database.yml` and replace the example `password:` value under `admin:` with your generated hash.
5. Ensure the `admin` user belongs to the `admins` and `users` groups as shown in the example.
* **Adding More Users:**
1. Generate a password hash for the new user as shown above.
2. Edit `authelia/users_database.yml`.
3. Add a new entry under `users:`, following the format of the `admin` user:
```yaml
users:
admin:
# ... (admin details) ...
newuser:
displayname: "New User Name"
password: "paste_generated_hash_here"
email: newuser@example.com
groups:
- users # Add to 'admins' group if needed
```
4. Save the file. Authelia should pick up the changes automatically (or restart the Authelia container: `docker compose restart authelia`).
* **Enabling User Registration (Optional):**
1. Edit `authelia/configuration.yml`.
2. Find the commented-out `registration:` section near the bottom.
3. Uncomment it and set `enable: true`:
```yaml
# registration:
# enable: false # Set to true to enable registration form
```
becomes:
```yaml
registration:
enable: true
```
4. Save the file and restart Authelia (`docker compose restart authelia`).
5. A "Register" link will now appear on the Authelia login page.
* **Approving Registered Users:**
1. When a user registers (if enabled), their details are added to `authelia/users_database.yml` but marked as `disabled: true`.
2. To approve them, edit `authelia/users_database.yml`.
3. Find the new user's entry.
4. Change `disabled: true` to `disabled: false` (or simply remove the `disabled: true` line).
5. Save the file. The user should now be able to log in.
### (Optional) VPN Configuration
*(Details about configuring the PIA VPN or other VPN setups could go here if needed.)*
### (Optional) Traefik DNS Challenge
*(Details about setting up DNS provider credentials for Let's Encrypt could go here if needed.)*
## Service Access
With the default Tailscale setup and Authelia enabled, services are securely accessible via HTTPS using your Tailscale node's name or IP. Access requires authentication via Authelia.
* **Login Portal:** `https://<TAILSCALE_NODE>/` (Redirects unauthenticated users here)
* **Homepage Dashboard:** `https://<TAILSCALE_NODE>/home` (Accessible after login)
* **Sonarr:** `https://<TAILSCALE_NODE>/sonarr` (Requires login)
* **Radarr:** `https://<TAILSCALE_NODE>/radarr` (Requires login)
* **qBittorrent:** `https://<TAILSCALE_NODE>/qbittorrent`
* **Jellyfin:** `https://<TAILSCALE_NODE>/jellyfin`
* ...and so on.
Replace `<TAILSCALE_NODE>` with your Tailscale device name (e.g., `tailscale-nas.your-tailnet.ts.net`) or its Tailscale IP address.
If you configure DNS for your `APP_HOSTNAME` variable to point to the Tailscale IP, you can use `https://<APP_HOSTNAME>/<service_path>`.
## Optional Services
Several services are included but disabled by default. Enable them by adding their profile name to the `COMPOSE_PROFILES` variable in your `.env` file (separate multiple profiles with commas).
Example: Enable Lidarr and SABnzbd
```dotenv
COMPOSE_PROFILES=lidarr,sabnzbd
```
Available Profiles:
* `lidarr`: Music management.
* `sabnzbd`: Usenet download client.
* `flaresolverr`: Bypasses Cloudflare challenges for Prowlarr.
* `adguardhome`: Network-wide ad blocking (see `adguardhome/README.md`).
* `calibre-web`: E-book library management.
* `decluttarr`: Automated download cleanup.
* `tandoor`: Recipe management (see `tandoor/README.md`).
* `joplin`: Note-taking server (see `joplin/README.md`).
* `homeassistant`: Home automation (see `homeassistant/README.md`).
* `immich`: Photo management (see `immich/README.md`).
## Troubleshooting
### SELinux Socket Permissions (Docker)
If you are running Docker on a host with SELinux enabled (like Fedora, CentOS, RHEL) and services like Traefik, Watchtower, or Autoheal fail with "permission denied" errors when trying to access `/var/run/docker.sock`:
1. **Check Audit Logs:** Immediately after seeing the error, check the SELinux audit log on the host:
```bash
sudo ausearch -m avc -ts recent
```
Look for lines containing `denied`, `docker.sock`, and the name of the failing service (e.g., `traefik`, `watchtower`).
2. **Generate Custom Policy:** If denials are found, you may need to create a custom SELinux policy module using `audit2allow`. Pipe the denial messages into it:
```bash
# Generate policy files (my-dockersock.te and my-dockersock.pp)
sudo ausearch -m avc -ts recent | audit2allow -M my-dockersock
# Install the policy module
sudo semodule -i my-dockersock.pp
```
This allows the specific actions that were being denied. You might need to repeat this if different denials appear after applying the first policy.
### Authelia v4.38+ Configuration
Authelia v4.38+ introduces significant changes to its configuration structure, particularly for session domains and authentication flows. This Docker Compose template has been updated to support these changes, making it easier to set up:
1. **Simplified Configuration**: The setup now uses a more reliable approach with wildcard domain matching (`*.ts.net`) that works properly with Tailscale domains. This eliminates environment variable interpolation issues that were causing errors in previous versions.
2. **No Manual YAML Editing Required**: You don't need to edit the Authelia configuration file manually. The important settings are configured through environment variables in the Docker Compose setup.
3. **Required Secret Variables**: You only need to set these four variables in your `.env` file:
- `AUTHELIA_JWT_SECRET`: Used for password reset tokens
- `AUTHELIA_SESSION_SECRET`: Used for session cookie encryption
- `AUTHELIA_STORAGE_ENCRYPTION_KEY`: Used for database encryption
- `AUTHELIA_REDIS_PASSWORD`: Used for Redis authentication
Generate strong random values for these with: `openssl rand -hex 32`
4. **File Permissions Fixed**: The Authelia container now runs with your user ID and group ID, preventing permission issues when managing the configuration files with git or other tools.
5. **Common Error Solutions**: If you encounter configuration errors like these:
```
error decoding 'session.cookies[0].authelia_url': could not decode 'https://${APP_HOSTNAME}'
can't be specified at the same time: option 'domain' and option 'cookies'
```
The solution is already implemented in the updated configuration. No manual fixes needed.
If you need to make changes to the domain settings for some reason, edit `authelia/configuration.yml` and modify the `*.ts.net` wildcard pattern to match your specific domain. For most setups using Tailscale, the default configuration will work without any changes.
After making changes to the configuration, restart Authelia with:
```bash
docker compose restart authelia
```
See the [Authelia documentation](https://www.authelia.com/configuration/session/introduction/) for more details on the v4.38+ configuration structure.
### Tailscale Issues
* **Authentication:** Ensure your `TAILSCALE_AUTHKEY` in `.env` is valid and hasn't expired (especially if using ephemeral keys). Check the `tailscale` container logs (`docker compose logs tailscale`) for authentication errors.
* **Connectivity:** Verify the `tailscale` container is running and connected to your Tailnet (`docker compose exec tailscale tailscale status`).
* **Funnel/Serve Command:** If you modified the Tailscale command, ensure the syntax for `tailscale funnel` or `tailscale serve` is correct.
### File Permissions
If services report permission errors when accessing `/config` or `/data` directories, double-check that:
* The `USER_ID` and `GROUP_ID` in your `.env` file match the owner/group of the corresponding `CONFIG_ROOT` and `DATA_ROOT` directories on your host.
* The host directories have appropriate read/write permissions for that user/group.
* If using SELinux, the `:Z` flag on the volume mounts in `docker-compose.yml` is correctly applied to allow the container to write to the host paths.
## Advanced Topics
*(Relevant sections like Synology Quirks, NFS Share, Static IP, etc., can be kept here, but review them to ensure they align with a standard Docker setup rather than Podman specifics where applicable.)*
*(Example: Synology section should focus on Docker package setup, port conflicts, user IDs, etc., relevant to DSM.)*
*(Example: Remove Podman-specific commands or troubleshooting steps from these sections.)*
