Support Heroku PrivateLink for Postgres

[zmsy]

Heroku PrivateLink for Postgres has been recently announced:

https://blog.heroku.com/heroku-postgres-privatelink
https://devcenter.heroku.com/articles/heroku-postgres-via-privatelink

Terraform Version / Heroku Provider Version

Terraform v0.11.14
+ provider.heroku v1.9.0

Affected Resource(s)

• heroku_space

Expected Behavior

Terraform is able to provision a privatelink endpoint similar to the manner described by the Heroku CLI here:

https://devcenter.heroku.com/articles/heroku-postgres-via-privatelink#step-3-create-a-privatelink-endpoint

This provider only supports features available in the GA (generally available) Heroku Platform API.

Unfortunately, the API used by the CLI & Dashboard to manage this feature is not part of the Platform API, and could be subject to change without warning.

Hi @zmsy,

I ended starting a separate provider for a lot of the resources backed by the CLIs: https://registry.terraform.io/providers/davidji99/herokux/latest/docs/resources/privatelink

Hope this helps.
