Here's my terraform-ization of an S3 + Cloudflare setup for SSGs. I use Zola but that's incidental.

There's a weird bug with the `tf init` but it can be worked around by running `tf init`, deleting the providers in `.terraform`, then running again. Hashicorp has an open bug for the problem I think.

I could probably clean it up more but this has been okay for a couple sites I run.
