Infrarust

High-Performance Minecraft Reverse Proxy in Rust

Compatible with almost all vanilla, plugin, and modded Minecraft servers

Warning

Infrarust is currently in active development. This project is a Rust implementation inspired by Infrared, focusing on performance and enhanced features.

A blazing fast Minecraft reverse proxy that allows you to expose multiple Minecraft servers through a single port. It uses domain/subdomain-based routing to direct clients to specific Minecraft servers.

Key Features

• Efficient Reverse Proxy
  • Wildcard Domain Support
  • Multi-Domain Routing
  • Direct IP Connection Support
• Authentication Modes
  • ClientOnly Mode (only works with vanilla < 1.20)
  • Passthrough Mode
  • Offline Mode
  • ServerOnly Mode
• Performance Optimizations
  • Connection Pooling
  • Zero-copy packet forwarding
  • Status Caching
• Security Features
  • Rate Limiting
  • Basic DDoS Protection
  • Advanced Ban System (IP, UUID, Username)
• Container Integration
  • Docker Auto-Discovery
  • Real-time Container Monitoring
• Command Line Interface
  • Player Management
  • Ban Management
  • Status Monitoring
• Basic Telemetry and Monitoring

Quick Start

Prerequisites

• Rust 1.84+ and Cargo

Installation

# From source
git clone https://github.com/shadowner/infrarust
cd infrarust
cargo build --release

# Or via cargo
cargo install infrarust

Basic Configuration

Create a config.yaml file:

bind: "0.0.0.0:25565"
file_provider:
  proxies_path: ["./proxies"]
  watch: true  # Enable hot-reload

And create your server configurations in the proxies directory:

# proxies/my-server.yml
domains:
  - "hub.minecraft.example.com"
addresses:
  - "localhost:25566"
proxyMode: "passthrough" # Options: passthrough, client_only, offline, server_only

Docker Integration

Infrarust can automatically detect and proxy Minecraft servers running in Docker containers:

docker_provider:
  docker_host: "unix:///var/run/docker.sock"
  label_prefix: "infrarust"
  watch: true

Container configuration is done through Docker labels:

infrarust.enable=true
infrarust.domains=mc.example.com

Telemetry & Monitoring

Infrarust provides comprehensive telemetry through OpenTelemetry integration, including metrics, traces, and logs. The project includes a ready-to-use monitoring stack in the docker/monitoring directory.

Quick Start Monitoring

cd docker/monitoring
docker compose up -d

This will start:

• Grafana (http://localhost:3000)
• Prometheus (http://localhost:9090)
• Tempo (Traces)
• OpenTelemetry Collector

Available Metrics

• Connection metrics (active connections, errors, latency)
• Backend metrics (server status, response times)
• System metrics (CPU, memory, threads)
• Minecraft-specific metrics (protocol errors, player count)

Performance

Infrarust leverages Rust's performance capabilities:

• Minimal memory footprint (~10MB base)
• Low CPU utilization
• Efficient async I/O handling
• Zero-copy packet forwarding when possible

Note

This project was initiated as a learning experience in advanced Rust programming, with continuous improvements and optimizations expected as development progresses.
