# GSP Deployment Script
# =====================
# This script deploys the Game Server Panel (GSP) from GitHub to a web server.
#
# HOW IT WORKS:
# 1. Clones/updates the GSP repository to a staging directory
# 2. Syncs files to the web root using rsync (preserving configs)
# 3. Sets proper permissions for OGP panel operation
#
# CONFIGURATION:
# All settings can be configured via environment variables or by editing
# the defaults in the "Config" section below.
#
# ENVIRONMENT VARIABLES:
# - REPO_URL: Git repository URL (default: https://github.com/GameServerPanel/GSP.git)
# - STAGE_DIR: Staging directory for git clone (default: $HOME/gsp_stage)
# - WEB_ROOT: Live web server directory (default: /var/www/html/panel)
# - OWNER: File owner user (default: www-data)
# - GROUP: File owner group (default: www-data)
# - SUDO: Command prefix for privilege escalation (default: sudo, set empty to skip)
# - DRY_RUN: Set to 1 to test without making changes (default: 0)
#
# EXAMPLE USAGE:
#   # Use defaults:
#   ./deploy_gsp.sh
#
#   # Custom web root:
#   WEB_ROOT=/home/panel/public_html ./deploy_gsp.sh
#
#   # Dry run to test:
#   DRY_RUN=1 ./deploy_gsp.sh
#
#   # Different user/group:
#   OWNER=apache GROUP=apache ./deploy_gsp.sh
