#!/usr/bin/env bash
# EXPERIMENTAL — AWS Lightsail smoke-lab provisioning for the CodeWhale
# remote workbench (issue #1990). Creates ONE Ubuntu 24.04 Lightsail
# instance with SSH-only firewall. Prints every step and the monthly price
# from the Lightsail API, then requires an explicit "yes" before creating
# anything that costs money.
#
# Usage:
# AWS_REGION=us-east-1 bash scripts/aws-lightsail/provision.sh
#
# Tunables (env):
# INSTANCE_NAME default codewhale-smoke
# BUNDLE_ID default medium_3_0 (2 vCPU / 4 GB — docs/REMOTE_VM_US.md default)
# BLUEPRINT_ID default ubuntu_24_04
# SSH_PUBKEY default ~/.ssh/id_ed25519.pub (imported as key pair)
# RESTRICT_SSH_TO_MY_IP default true (firewall cidr = caller IP /32)
