install.sh

#!/bin/bash
# RustRconServerManager installer.
# Downloads docker-compose.yml (if not already present), generates a .env with random
# credentials, then pulls and starts the published Docker images. Works standalone -
# you do NOT need to clone the full source repo, just this one script.
#
# Usage (interactive):
#   ./install.sh
#
# Usage (non-interactive):
#   ./install.sh --port <port> --pathbase <path>
#
# One-liner:
#   curl -fsSL https://raw.githubusercontent.com/Xenne93/RustRconServerManager/main/install.sh | bash
