This repository provides two Terraform modules:

• ./nixos - A Terraform module for auto-deploying a NixOS configuration to a target host

• ./ami - A Terraform module for computing the correct NixOS AMI to use

You can find an example Terraform project using these modules in the ./example directory.

The main reason this repository exists is because the terraform-nixos repository is abandoned. I wanted to simplify the upstream project in two major ways:

• I wanted to simplify the deployment logic with nixos-rebuild

  … using the trick documented in this blog post

• I wanted to simplify the AMI module

  … by not requiring the list to be manually updated like this

However, since the upstream project doesn't appear to be maintained I created my own opinionated fork that is simpler than the original. The main omissions compared to the original are:

• No support for secrets management

  However, you can use this in conjunction with sops-nix if you need secrets management

• No support for GCE images (yet)

  … mainly because I don't use Google Compute Engine, but I'd accept a PR to add support following the same pattern as the ami module.
