#!/usr/bin/env bash
#
# Deploy Moltbot to Google Compute Engine (follows docs/platforms/gcp.md)
#
# Usage:
#   ./scripts/deploy/google/compute-engine/run.sh [OPTIONS]
#
# Options:
#   --project PROJECT_ID    Google Cloud project ID (required)
#   --zone ZONE             Compute Engine zone (default: us-central1-a)
#   --instance NAME         Instance name (default: moltbot-gateway)
#   --machine-type TYPE     Machine type (default: e2-medium, 4GB RAM for builds)
#   --disk-size SIZE        Boot disk size (default: 20GB)
#   --env-file FILE         Upload .env file to the instance
#   --anthropic-key KEY     Anthropic API key
#   --gateway-token TOKEN   Gateway token (auto-generated if not provided)
#   --public                Expose gateway publicly to all IPs (not recommended)
#   --allowed-ip IP         Expose gateway but restrict to specific IP
#   --my-ip                 Auto-detect your IP, confirm, and restrict access to it (recommended)
#   --tailscale             Install Tailscale for HTTPS access (recommended)
#   --telegram-token TOKEN  Telegram bot token (from @BotFather)
#   --telegram-user-id ID   Your Telegram user ID (auto-approves you, skips pairing)
#   --help                  Show this help message
#
# Examples:
#   # Production deployment (e2-small, SSH tunnel access - most secure)
#   ./scripts/deploy/google/compute-engine/run.sh --project my-project --anthropic-key sk-ant-xxx
#
#   # Restrict access to your IP only (recommended - auto-detects and confirms)
#   ./scripts/deploy/google/compute-engine/run.sh --project my-project --anthropic-key sk-ant-xxx --my-ip
#
#   # Free tier deployment (e2-micro, may OOM under load)
#   ./scripts/deploy/google/compute-engine/run.sh --project my-project --machine-type e2-micro --anthropic-key sk-ant-xxx
#
#   # With .env file
#   ./scripts/deploy/google/compute-engine/run.sh --project my-project --env-file .env
#
# Prerequisites:
#   - gcloud CLI installed and authenticated
#   - Google Cloud project with billing enabled
