## Prerequisites
- [Rust](https://rustup.rs/) 1.93.1+
- [Docker](https://docs.docker.com/get-docker/)
- A [Vultr](https://www.vultr.com/) account
- A [Cloudflare](https://www.cloudflare.com/) account (for DNS, CDN, and Origin certificates)
- An S3-compatible bucket for Terraform state (e.g. Cloudflare R2)
- [Docker](https://docs.docker.com/get-docker/) and [Docker Compose](https://docs.docker.com/compose/install/)
- A [Cloudflare](https://www.cloudflare.com/) account with your domain proxied through it
- A Cloudflare Origin certificate for TLS between Cloudflare and your server
For building from source without Docker, you also need [Rust](https://rustup.rs/) 1.93.1+.
This project is designed to run behind Cloudflare. The application relies on the `CF-Connecting-IP` header to identify clients, and the included HAProxy configuration assumes Cloudflare as the TLS edge.
## Quick Start with Docker Compose
This is the recommended way to deploy RustyIP. It runs the application behind HAProxy with TLS termination and rate limiting.
### 1. Configure environment
```bash
cp .env.example .env
```
Edit `.env` and set at minimum:
```
SITE_DOMAIN=your-domain.example.com
```
### 2. Provide TLS certificates
Generate an Origin certificate in the Cloudflare dashboard under **SSL/TLS > Origin Server**. Place the combined certificate and key in PEM format at `haproxy/certs/origin.pem`:
```bash
mkdir -p haproxy/certs
cat origin-cert.pem origin-key.pem > haproxy/certs/origin.pem
```
The file must contain the certificate followed by the private key.
### 3. Start the stack
A prebuilt image is available on Docker Hub at [`networkcat/rustyip`](https://hub.docker.com/r/networkcat/rustyip). Update the `app` service in `docker-compose.yml` to use it:
```yaml
app:
image: networkcat/rustyip
```
Then start the stack:
```bash
docker compose up -d
```
If you prefer to build from source instead, keep the default `build: .` and run:
```bash
docker compose up -d --build
```
The service will be available on port 443 (HTTPS). The MMDB database is downloaded automatically on first start and updated periodically (every 24 hours by default).
### 4. Configure Cloudflare
In the Cloudflare dashboard for your domain:
1. Add a DNS A record pointing to your server IP with the proxy enabled (orange cloud).
2. Set **SSL/TLS** mode to **Full (strict)**.

| Variable | Default | Description |

| `LISTEN_ADDR` | `0.0.0.0:3000` | Address and port the server listens on |
| `DB_PATH` | `data/Merged-IP.mmdb` | Path to the MMDB database file |
| `DB_UPDATE_URL` | *(GitHub release URL)* | URL to download the MMDB database from |
| `DB_UPDATE_INTERVAL_HOURS` | `24` | How often to check for database updates |
| `SITE_DOMAIN` | `localhost` | Domain name used for display and metadata |
| `DEV_MODE` | `false` | Uses `1.1.1.1` as fallback when `CF-Connecting-IP` is absent |

## Automated Deployment via GitHub Actions
## Automated CI/CD Deployment
Pushing a version tag (e.g. `v1.0.0`) triggers the full deployment pipeline:
```
v* tag push --> CI checks --> Docker build + push to Docker Hub --> Terraform + Ansible deploy
```
### Pipeline Overview
1. **Check** -- Runs `cargo fmt`, `cargo clippy`, and `cargo test`.
2. **Build** -- Builds a Docker image and pushes it to Docker Hub (`docker.io/networkcat/rustyip`).
3. **Deploy** -- Provisions infrastructure with Terraform and configures/deploys with Ansible.
The deploy job uses a `production` environment with concurrency control to prevent overlapping deployments.
### Required GitHub Secrets
Go to **Settings > Secrets and variables > Actions** in your GitHub repository and add the following secrets.
If you are using environments, add them under the `production` environment (**Settings > Environments > production**).
#### Terraform State (S3-compatible backend)
| Secret | Description |
|---|---|
| `TF_STATE_ACCESS_KEY` | Access key for the S3-compatible state backend (e.g. Cloudflare R2) |
| `TF_STATE_SECRET_KEY` | Secret key for the S3-compatible state backend |
| `TF_STATE_BUCKET` | Bucket name where Terraform state is stored |
| `TF_STATE_ENDPOINT` | S3-compatible endpoint URL (e.g. `https://<account_id>.r2.cloudflarestorage.com`) |
#### Infrastructure
| Secret | Description |
|---|---|
| `VULTR_API_KEY` | Vultr API key for provisioning VPS and firewall resources |
| `SSH_PUBLIC_KEY` | Public key deployed to the VPS for SSH access |
| `SSH_PRIVATE_KEY` | Corresponding private key used by the pipeline to connect via SSH |
#### Application
| Secret | Description |
|---|---|
| `SITE_DOMAIN` | Production domain name (e.g. `ip.nc.gy`) |
| `DB_UPDATE_URL` | URL to download the MMDB database from |
#### TLS
| Secret | Description |
|---|---|
| `ORIGIN_CERT` | Cloudflare Origin certificate (PEM) for TLS termination at HAProxy |
| `ORIGIN_KEY` | Corresponding private key (PEM) for the Origin certificate |
#### Docker Hub
| Secret | Description |
|---|---|
| `DOCKERHUB_USERNAME` | Docker Hub username used for image push and pull |
| `DOCKERHUB_TOKEN` | Docker Hub access token for authentication |
### Deploying
```bash
git tag v1.0.0
git push origin v1.0.0
```
This triggers the full pipeline. Monitor progress under the **Actions** tab in the repository.
### Infrastructure Details
- **VPS**: Vultr High Frequency (`vhf-2c-2gb`), Debian 13, region `dfw` (Dallas)
- **Firewall**: SSH open, HTTPS restricted to Cloudflare IP ranges
- **Deployment**: Blue-green with HAProxy traffic switching
- **First deploy**: Automatically applies base OS hardening (UFW, fail2ban, sysctl tuning) and installs Docker
- **Subsequent deploys**: Only the application container is updated via blue-green swap
For production deployment with Terraform and Ansible via GitHub Actions, see [deploy/INSTALL.md](deploy/INSTALL.md).
