Referring to terraform created resources as providers

Hi!

In my terraform I’m creating multiple mysql engines with random passwords using the helm_release resource of the helm provider.

I would then like to use these newly available mysql engines in a mysql provider block, so I can create databases in them and populate those.

Essentially, I would create the infrastructure using terraform and then setup databases, database users and database content, for an application to use (which I also deploy using terraform, offcourse.)

How would I go about this?

I’ve been trying to use variables inside providers, but this seems unsupported, and has an open github issue at https://github.com/hashicorp/terraform/issues/3656

Thanks for any pointers!
