| 2 | # EXPERIMENTAL — AWS Lightsail smoke-lab provisioning for the CodeWhale |
| 3 | # remote workbench (issue #1990). Creates ONE Ubuntu 24.04 Lightsail |
| 4 | # instance with SSH-only firewall. Prints every step and the monthly price |
| 5 | # from the Lightsail API, then requires an explicit "yes" before creating |
| 6 | # anything that costs money. |
| 7 | # |
| 8 | # Usage: |
| 9 | # AWS_REGION=us-east-1 bash scripts/aws-lightsail/provision.sh |
| 10 | # |
| 11 | # Tunables (env): |
| 12 | # INSTANCE_NAME default codewhale-smoke |
| 13 | # BUNDLE_ID default medium_3_0 (2 vCPU / 4 GB — docs/REMOTE_VM_US.md default) |
| 14 | # BLUEPRINT_ID default ubuntu_24_04 |
| 15 | # SSH_PUBKEY default ~/.ssh/id_ed25519.pub (imported as key pair) |
| 16 | # RESTRICT_SSH_TO_MY_IP default true (firewall cidr = caller IP /32) |
