Rux Playground Setup

Deployment files for the Rux Language Playground — a sandboxed in-browser playground for the Rux compiler, running on Debian 12 with Docker and Cloudflare Tunnel.

Files

File	Purpose
setup.sh	Full deployment script (8 phases)
main.go	Go HTTP backend serving /run and embedded UI
index.html	Web UI with CodeMirror editor
Dockerfile	Fedora container with Rux + cached Std/Linux packages
entrypoint.sh	Container entrypoint — creates project, installs deps, builds, runs
rux-playground.service	systemd unit for the Go backend

Architecture

• Go backend serves the web UI and handles POST /run by spawning a Docker container
• Fedora container runs the Rux compiler with --cap-drop=ALL, --network=none, 30s timeout
• Cloudflare Tunnel provides HTTPS without opening firewall ports

Quick Start

# Full deploy
sudo bash setup.sh all

# Upgrade everything
sudo bash setup.sh 9

See setup.sh for individual phase numbers.
