# 037 - Split install stack tfvars

> Install stack Terraform config is now split into inputs.auto.tfvars and secrets.auto.tfvars.

*July 3, 2026*

## Split install stack tfvars

The Terraform install stack config is now generated as two separate, auto-loaded files instead of a single
`install.tfvars`:

* **`inputs.auto.tfvars`** — install identity, runner settings, IAM operation roles, and `install_inputs`.
* **`secrets.auto.tfvars`** — `secrets` and `auto_generate_secrets`.

Both use the `.auto.tfvars` suffix, so Terraform loads them automatically. The apply command drops the `-var-file`
flag:

```bash theme={null}
terraform init && terraform apply
```

The provision workflow's "await install stack" step in the dashboard now shows each file in its own block, each with
its own copy and download buttons, so you can hand the non-secret config and the secrets to different owners.

This applies to both the [AWS](/platform-support/aws) and [GCP](/platform-support/gcp) Terraform install stacks.
