You can use Terraform to create, manage and delete Cloud Spanner resources. Google Terraform modules provide Cloud Spanner support via the following resources:

• google_spanner_instance
• google_spanner_instance_iam
• google_spanner_database
• google_spanner_database_iam

Google Terraform modules can be authenticated

• A service key in JSON format, see documentation for more.
• Application Default Credentials (ADC), automatically available on GCP machines or via gcloud auth application-default login.

You can checkout into the following directories and run terraform apply to create a plan and apply changes. The following examples use Application Default Credentials (ADC) to authenticate. Refer to the credentials file to authenticate with a service account.

Edit the main.tf file and replace YOUR_PROJECT_ID with your Google Cloud project ID.

• regional - Regional cluster with a database.
• multi-regional - Multi-regional cluster with a database.
• lifecycle - Database protected with lifecycle argument against accidental deletion.

Alternatively, a step-by-step tutorial is also available as a codelab.

Please file bugs and feedback to the Cloud Spanner Terraform resources on the Google Terraform Module. Issues and feedback to the examples are appreciated on this repo.
