# 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. You can configure which services require authentication via environment variables.
## 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):**

## 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
6. **⚠️ Optional: Authentication Configuration**
- Choose which services require authentication by setting the corresponding variables in your `.env` file:
```
AUTH_JELLYFIN=false # Example: Allow Jellyfin access without authentication
AUTH_SONARR=true # Example: Require authentication for Sonarr
```
- By default, all services require authentication if not specified otherwise
## Quick Start Guide
After completing all [Required Setup Steps](#required-setup-steps) above, follow these steps to get up and running:
1. **Clone Repository:**
```bash
git clone https://github.com/AdrienPoupa/docker-compose-nas.git
cd docker-compose-nas
```
2. **Configure Environment:**
```bash
# Create an .env file from the example
cp .env.example .env
# Edit the .env file and fill in ALL required values
nano .env
```
3. **Configure Authelia Admin:**
```bash
# Generate a password hash
docker run --rm authelia/authelia:latest authelia hash-password 'your_secure_password'
# Edit the users_database.yml with the generated hash
nano authelia/users_database.yml
```
4. **Run the Setup Script:**
```bash
# Make the script executable
chmod +x ./update-setup.sh
# Run the setup tool
./update-setup.sh
```
This interactive script will guide you through:
- Updating your `.env` file while preserving existing values
- Configuring Authelia with your Tailscale domain settings
- Setting up service configurations and retrieving API keys
5. **Start the Stack:**
```bash
# Start containers
docker compose up -d
```
*(Wait for containers to download and start)*
6. **Access Your NAS:**
- Open `https://<TAILSCALE_HOSTNAME>.<TAILSCALE_TAILNET_DOMAIN>/`
- Log in with username `admin` and the password you set
- After login, you'll land on the Homepage dashboard at `/home`
> ⚠️ **IMPORTANT:** If the stack fails to start, check the [Troubleshooting](#troubleshooting) section and verify you've properly completed all [Required Setup Steps](#required-setup-steps).

## 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. Authentication is controlled by the `AUTH_*` environment variables.
* **Login Portal:** `https://<TAILSCALE_NODE>/` (Redirects unauthenticated users here for secured services)
* **Homepage Dashboard:** `https://<TAILSCALE_NODE>/home` (Requires login if `AUTH_HOMEPAGE=true`)
* **Sonarr:** `https://<TAILSCALE_NODE>/sonarr` (Requires login if `AUTH_SONARR=true`)
* **Radarr:** `https://<TAILSCALE_NODE>/radarr` (Requires login if `AUTH_RADARR=true`)
* **qBittorrent:** `https://<TAILSCALE_NODE>/qbittorrent` (Requires login if `AUTH_QBITTORRENT=true`)
* **Jellyfin:** `https://<TAILSCALE_NODE>/jellyfin` (Requires login if `AUTH_JELLYFIN=true`, default is `false`)
* ...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>`.
### Configuring Authentication Per Service
You can control which services require authentication by setting the appropriate variables in your `.env` file:
```bash
# Example: Allow Jellyfin and qBittorrent without authentication, require it for others
AUTH_JELLYFIN=false
AUTH_QBITTORRENT=false
AUTH_SONARR=true
AUTH_RADARR=true
# ...and so on
```
If a variable is not explicitly set, authentication defaults to `true` for that service (except for Jellyfin, which defaults to `false`).
## 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
### Middleware Not Found Errors
If you see error messages like `middleware "authelia-auth@docker" does not exist` in the Traefik logs, it could be due to one of these issues:
1. **Docker Network Issue:** The Traefik configuration has been updated to fix network discovery issues when running in Tailscale's network namespace. If you're still seeing this error, try restarting the stack with:
```bash
docker compose down
docker compose up -d
```
2. **Authentication Variable Missing:** Ensure you have properly configured the `AUTH_*` variables in your `.env` file for the services you want to control. If not specified, most services default to requiring authentication.
3. **Docker Socket Permissions:** Make sure Traefik can access the Docker socket. See the [SELinux Socket Permissions](#selinux-socket-permissions-docker) section below for more details.
### 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. The setup in this repository has been carefully configured to work with these changes:
1. **Domain Configuration**:
- You must use your specific Tailnet domain (e.g., `example.ts.net`) for cookies, not just `ts.net`
- The domain `ts.net` is part of the [Public Suffix List](https://publicsuffix.org/), which means browsers restrict cookies on it for security reasons
- Authelia will refuse to start if you try to use a domain from this list
2. **Required Secret Variables**: You must 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`
3. **Automatic Domain Setup**: The `update-setup.sh` script automatically:
- Uses your specific Tailnet domain (e.g., `example.ts.net`) from your `.env` file
- Configures cookie domains properly to avoid Public Suffix List issues
- Sets up proper access control rules for both your domain and its subdomains
4. **File Permissions**: The Authelia container runs with your user ID and group ID, preventing permission issues when managing the configuration files with git or other tools.
If you encounter any of these common errors, running the setup script should resolve them:
```
error: option 'domain' is not a valid cookie domain: the domain is part of the special public suffix list
error: option 'authelia_url' does not share a cookie scope with domain
error: can't be specified at the same time: option 'domain' and option 'cookies'
configuration key 'jwt_secret' is deprecated in 4.38.0
```
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.
