RDS Extended Support Cost Lint for Terraform

Runs the same checker as our npm package on a Node.js runtime that pip installs for you (nodejs-wheel-binaries) - no system Node.js needed. Your files are checked locally.

Prices the AWS Extended Support surcharge on every RDS and Aurora database in your .tf files

• --rules lists every rule

With a licence ($29 once)

• Scans every .tf file in the workspace in one run and exports one Markdown report of every database's surcharge for the budget or upgrade ticket.
