## 🏁 Getting Started ## 🏁 Getting Started
You can run this application easily using Docker and Docker Compose. ### Using Pre-built Images (Recommended)
### Prerequisites
* [Docker](https://docs.docker.com/get-docker/) installed
* [Docker Compose](https://docs.docker.com/compose/install/) installed (usually included with Docker Desktop)
### Option 1: Using Pre-built Images (Recommended)
This method uses the Docker images automatically built and pushed to GitHub Container Registry (GHCR) by the GitHub Actions workflow.
1. **Create `compose.yml`:** 1. **Create `compose.yml`:**
Save the following content as `compose.yml` in a new directory on your machine: (See provided `compose.yml` in repository)
```yaml 2. **Start:**
services:
# Backend Service (Node.js App)
backend:
# Verwendet ein bereits gebautes Image
image: ghcr.io/mrunknownde/utools-backend:latest
container_name: utools_backend
restart: unless-stopped
environment:
# Setze Umgebungsvariablen für das Backend
NODE_ENV: production # Wichtig für Performance und Logging
PORT: 3000 # Port innerhalb des Containers
LOG_LEVEL: info # Oder 'warn' für weniger Logs in Produktion
PING_COUNT: 4
# Sentry DSN aus der Umgebung/ .env Datei übernehmen
SENTRY_DSN: "https://7ea70caba68f548fb96482a573006a7b@o447623.ingest.us.sentry.io/4509062020333568" # Wichtig für die Laufzeit
dns:
- 1.1.1.1 # Cloudflare DNS
- 1.0.0.1 # Cloudflare DNS
- 8.8.8.8 # Google DNS
- 8.8.4.4 # Google DNS
networks:
- utools_network # Verbinde mit unserem benutzerdefinierten Netzwerk
# Frontend Service (Nginx)
frontend:
# Verwendet ein bereits gebautes Image
image: ghcr.io/mrunknownde/utools-frontend:latest
container_name: utools_frontend
restart: unless-stopped
ports:
# Mappe Port 8080 vom Host auf Port 80 im Container (wo Nginx lauscht)
# Zugriff von außen (Browser) erfolgt über localhost:8080
- "8080:80"
depends_on:
- backend # Stellt sicher, dass Backend gestartet wird (aber nicht unbedingt bereit ist)
networks:
- utools_network # Verbinde mit unserem benutzerdefinierten Netzwerk
# Definiere ein benutzerdefiniertes Netzwerk (gute Praxis)
networks:
utools_network:
driver: bridge
```
2. **Start the Application:**
Open a terminal in the directory where you saved the `compose.yml` file and run:
```bash ```bash
docker compose up -d docker compose up -d
``` ```
*(Note: Use `docker-compose` (with hyphen) if you have an older version)*
This will download the images (if not already present) and start the containers in the background.
3. **Access the Webapp:** 3. **Access:** `http://localhost:8080`
Open your web browser and navigate to `http://localhost:8080`.
### Option 2: Building Images from Source
If you want to modify the code or build the images yourself, the project is now split into a build and a run configuration.
1. **Clone the Repository:**
```bash
git clone https://github.com/mrunknownde/utools.git
cd utools
```
2. **Build and Start:**
First, you build the images using `compose.build.yml`. Then, you start the services using the main `compose.yml`.
```bash
# Set GIT_COMMIT_SHA for the build process
export GIT_COMMIT_SHA=$(git rev-parse --short HEAD)
# 1. Build the images
docker compose -f compose.build.yml build
# 2. Run the services using the newly built images
docker compose -f compose.yml up -d
```
You can also use the provided `build.sh` script which does these steps for you.
3. **Access the Webapp:**
Open your web browser and navigate to `http://localhost:8080`.
## ⚙️ Configuration ## ⚙️ Configuration
The application is configured mainly through environment variables set in the `compose.yml` file for the `backend` service: Key environment variables for the backend:
* `NODE_ENV`: `production` or `development`.
* `NODE_ENV`: Set to `production` for optimal performance and JSON logging. * `PORT`: Internal port (default 3000).
* `PORT`: The internal port the Node.js application listens on (default: `3000`). * `RATE_LIMIT_MAX`: Requests per window (e.g., 50).
* `LOG_LEVEL`: Controls the logging verbosity (e.g., `debug`, `info`, `warn`, `error`). * `SENTRY_DSN`: Optional Sentry integration.
* `PING_COUNT`: Number of ping packets to send (default: `4`).
* `SENTRY_DSN` (Optional): Your Sentry Data Source Name for error tracking. Can be set during build via args or at runtime via environment variable.
* `dns` (in compose): Specifies DNS servers for the backend container, crucial for reliable rDNS lookups.
The MaxMind database paths (`GEOIP_CITY_DB`, `GEOIP_ASN_DB`) are set within the backend's Dockerfile but could potentially be overridden if needed (e.g., using volumes).
## 🌐 Data Sources ## 🌐 Data Sources
* **Geolocation & ASN:** This tool uses GeoLite2 data created by MaxMind, available from [https://www.maxmind.com](https://www.maxmind.com). * **Geolocation:** [MaxMind GeoLite2](https://www.maxmind.com).
* **Important:** The GeoLite2 databases require periodic updates. You need a MaxMind account (free) to download them. The Docker images contain the databases at build time. For long-term use, you should implement a process to update the `.mmdb` files within the `backend/data` directory (if using volumes) or rebuild the backend image regularly using the provided GitHub Action workflow (`maxmind-update.yml`). * **Map Tiles:** [OpenStreetMap](https://www.openstreetmap.org) & [CartoDB](https://carto.com).
* **Map Tiles:** Provided by OpenStreetMap contributors. * **MAC Data:** [IEEE OUI](https://standards.ieee.org/products-services/regauth/oui/index.html).
* **WHOIS Data:** Retrieved in real-time using the `whois-json` library, which queries standard WHOIS servers.
* **DNS Data:** Retrieved in real-time using Node.js' built-in `dns` module.
