Toggle environment group for previews

I’m trying to set up blueprints to be able to deploy a whole preview env and I’d like to be able to simply toggle which env group to use rather than toggling individual env vars. This also seems to make more sense than your examples which show toggling individual vars within the render.yaml file as this would mean including those sensitive keys in version control…

For example, you can imagine I have several environment groups defined outside of the render.yaml file

  • api-prod (has my production keys and any prod settings)
  • api-staging (has dev/test keys and other staging settings)

and then in the render.yaml, something like

  - fromGroup:
      value: prod-env
      previewValue: staging-env

Please let me know best practices for this situation and if I’m missing something obvious.
