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

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

GPU Detection: Automatically identifies NVIDIA GPUs using system tools
Method Selection: Chooses GameStream (NVIDIA) or Sunshine (alternative)
Server Setup: Configures streaming server with optimal settings
Client Installation: Installs Moonlight client for remote access
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
