Awesome to see this. Thank you for the contribution. Minor comments and some 404s on urls. Assume the repo is not yet public?

Thanks @vara-bonthu - we're still working on getting some things on our side squared away before we publish the final (= 0.9.0) of this add-on to the Terraform Registry.

If y'all could wait with merging this until then, that would be very helpful!

Hey folks! We've made an initial version of the module code available at the links present in this PR.

We anticipate down-the-road changes and may release newer module versions.

For now, please give Vault a try with the included example.
