Moonlight/GameStream Module for Coder Workspaces

Overview

This PR implements Moonlight streaming support for GPU-accelerated remote desktop access in Coder workspaces. The module automatically detects compatible hardware and configures either NVIDIA GameStream or Sunshine server based on the available GPU.

Features

  • Automatic GPU Detection - Identifies NVIDIA GPUs and compatible hardware
  • Smart Server Selection - Automatically chooses GameStream (NVIDIA) or Sunshine (alternative)
  • Cross-Platform Support - Windows and Linux compatibility
  • Quality Optimization - Configurable streaming quality (low/medium/high/ultra)
  • Network Optimization - Automatic port forwarding and firewall configuration
  • Coder App Integration - Exposes Moonlight as a Coder app for easy access

Files Added

  • registry/Majain004/modules/moonlight/main.tf - Main Terraform module with GPU detection
  • registry/Majain004/modules/moonlight/scripts/install-moonlight.ps1 - Windows installation script
  • registry/Majain004/modules/moonlight/scripts/install-moonlight.sh - Linux installation script
  • registry/Majain004/modules/moonlight/scripts/detect-gpu.ps1 - Windows GPU detection
  • registry/Majain004/modules/moonlight/scripts/detect-gpu.sh - Linux GPU detection
  • registry/Majain004/modules/moonlight/README.md - Comprehensive documentation
  • registry/Majain004/modules/moonlight/main.test.ts - Automated tests (8 test cases)

Usage

module "moonlight" {
  count            = data.coder_workspace.me.start_count
  source           = "registry.coder.com/Majain004/moonlight/coder"
  version          = "1.0.0"
  agent_id         = resource.coder_agent.main.id
  os               = "windows" # or "linux"
  streaming_method = "auto"    # "auto", "gamestream", or "sunshine"
  port             = 47984
  quality          = "high"    # "low", "medium", "high", "ultra"
  subdomain        = true
}

Technical Implementation

GPU Detection

  • Windows: Uses WMI to detect NVIDIA GPUs and GeForce Experience
  • Linux: Uses lspci and nvidia-smi to detect NVIDIA hardware
  • Auto Selection: Chooses GameStream for NVIDIA GPUs, Sunshine for others

Streaming Methods

  • GameStream: NVIDIA's streaming technology (requires NVIDIA GPU + GeForce Experience)
  • Sunshine: Open-source GameStream server (works with any GPU)
  • Auto: Automatically selects the best method based on hardware

Quality Settings

  • Low: 720p, 30fps - Good for basic remote access
  • Medium: 1080p, 30fps - Balanced performance and quality
  • High: 1080p, 60fps - Recommended for gaming
  • Ultra: 4K, 60fps - Maximum quality (requires strong network)

Requirements

  • Hardware: NVIDIA GPU (for GameStream) or compatible GPU (for Sunshine)
  • Windows: Windows 10+ with NVIDIA drivers (for GameStream)
  • Linux: Desktop environment with GPU support
  • Network: Outbound internet access for Moonlight client download
  • Moonlight Account: Free account for authentication

How it Works

  1. GPU Detection: Automatically identifies NVIDIA GPUs using system tools
  2. Method Selection: Chooses GameStream (NVIDIA) or Sunshine (alternative)
  3. Server Setup: Configures streaming server with optimal settings
  4. Client Installation: Installs Moonlight client for remote access
  5. Network Configuration: Sets up port forwarding and firewall rules

Testing

All 8 tests pass successfully, covering:

  • Windows and Linux compatibility
  • GameStream and Sunshine configurations
  • Auto detection scenarios
  • Custom port and quality settings
  • Subdomain configurations
  • GPU detection validation
