Spacelift support for install stacks is gated behind a feature flag. Reach out to Nuon to enable it for your org.
The Terraform install stack provisions the runner in your customer’s cloud account. It can be provisioned with the Terraform CLI, but customers can also manage it as a Spacelift stack. This works with any Terraform install stack — AWS and GCP. There are two ways to install a Spacelift stack. Which one your customer uses depends on whether they want to use the Spacelift web UI or the Spacelift Terraform provider.
  • Blueprint — publish a Spacelift blueprint and use the web UI to create the stack.
  • Terraform — apply a generated spacelift.tf that uses the Terraform provider to create the stack.
Both paths run the same nuonco/install-stacks module over raw Git, so no Spacelift VCS integration or GitHub App install is required.

​
Prerequisites

  • Enable the feature flag — Spacelift support is gated behind a feature flag. Reach out to Nuon to enable it — the Spacelift tab then appears on the await install stack step.
  • Create a Spacelift account — you need a Spacelift account with permission to create blueprints and stacks.
  • Configure a cloud integration — set up Spacelift’s cloud integration for your target cloud — AWS or GCP. Its identity must have access to provision resources in the target account.

​
Use a blueprint

1

Create the blueprint

In Spacelift, go to Blueprints → Create blueprint and paste the generated YAML from the dashboard as the template body. It starts as a draft you can edit freely. See Blueprints.
2

Publish it

Click Publish to move the blueprint from draft to published. The template clones the public install-stacks repository over raw Git, so no VCS integration setup is required. Publishing is one-way — to change a published blueprint, clone it, edit, and publish again.
3

Create a stack and fill in the inputs

On the published blueprint, click Create stack and fill in the cloud settings (such as the account, project, or region for your target cloud) and any install inputs and secrets. These are declared as blueprint inputs; secrets use the secret input type. This creates the stack but doesn’t run it yet.
4

Attach cloud credentials, then trigger the run

Open the new stack’s Settings → Integrations and attach your cloud integration. Then trigger the stack’s first run — it provisions the runner. The run isn’t triggered automatically because cloud credentials can’t be attached from the blueprint itself.

​
Use terraform

This path applies a generated spacelift.tf alongside its inputs.auto.tfvars and secrets.auto.tfvars sibling files. The config reads the tfvars via filebase64, so you can edit the inputs and replace the secrets with real values before applying.
1

Save these files together

Download spacelift.tf, inputs.auto.tfvars, and secrets.auto.tfvars from the dashboard and put all three in one directory. Edit inputs.auto.tfvars as needed and replace secrets.auto.tfvars with your real secret values. Keep them somewhere private — the secrets file is plaintext at rest.
2

Authenticate the provider to Spacelift

The spacelift-io/spacelift provider needs Spacelift API credentials. Create an API key and export it as SPACELIFT_API_KEY_ENDPOINT, SPACELIFT_API_KEY_ID, and SPACELIFT_API_KEY_SECRET before applying. See the provider authentication docs.
3

Apply with Terraform

Run:
terraform init && terraform apply
This creates the install stack and mounts your tfvars via spacelift_stack and spacelift_mounted_file.
4

Attach cloud credentials, then run the install stack

Open the created install stack’s Settings → Integrations and attach your cloud integration. A newly created stack doesn’t run on its own, so trigger its first run — it’s set to auto-deploy, so it plans and applies your runner without further approval.
