Create Resources with Terraform

Prerequisites:

Install Terraform

Authenticate to Google Cloud Platform (GCP)

gcloud auth login application-default

Create Airflow Service Account (GCP -> IAM)

Running the below commands will create a service account in GCP that Airflow will use to connect to BigQuery (BQ). It will also assign the roles BigQuery Data Editor, BigQuery Job User, and BigQuery Data Viewer.

Check out the service account module to see how the resources are created.

Using your terminal:

1. Navigate to the terraform directory

   cd terraform

2. Open terraform.tfvars and update with your project id and location to save key file

   // replace with your GCP project ID
   project_id           = "gcp-project-id"
   
   // replace with the location to save service account key file
   key_file_path        = "/Users/username/bigquery-key.json"

3. Initialize Terraform

   terraform init

4. Run a Plan Returns an output of resources to be created

   terraform plan

5. Apply configuration Applies the configuration as reflected on the plan

   terraform apply

6. Destroy (optional) If you would like to destroy the resources used for this demo once you're done

   terraform destroy
