MRH-G2Ray is a containerized application that sets up a VLESS proxy server (Xray) on GitHub Codespaces, providing a free, ephemeral proxy service. The system automatically generates a unique UUID per Codespace, configures Xray with VLESS over XHTTP, and exposes an admin web panel (port 8080) with HTTP Basic Auth for easy retrieval of the VLESS connection link. The architecture is a single Docker container running both Xray and a Python-based admin server, orchestrated via devcontainer configuration. It is designed for users in restricted regions to bypass internet censorship using GitHub's free cloud infrastructure. The codebase is modular with separate startup scripts, but tightly coupled to the specific Xray configuration and Codespaces environment.
