Which configuration allows Jenkins to create GCP resources with Terraform?

Creating a dedicated service account for Terraform in Google Cloud Platform (GCP) is the most appropriate configuration for allowing Jenkins to manage GCP resources using Terraform. This approach offers several advantages:

1. Granular Permissions: By creating a dedicated service account, you can configure specific permissions that are necessary for Terraform to interact with GCP resources. This principle of least privilege ensures that the account has only the rights it needs for its tasks, reducing security risks.

2. Isolation: A dedicated service account isolates the Terraform operations from other processes and services that might be using GCP. This separation helps in tracking actions performed by Terraform and debugging any issues that arise.

3. Easier Management: Having a dedicated service account for Terraform allows for easier management of credentials and access. If there are changes needed in permissions or roles, it can be done specifically for this account without impacting other service accounts.

4. Audit and Monitoring: You can closely monitor the actions taken by this specific service account, making it easier to audit and understand what changes are made to your GCP infrastructure through Terraform.

Other configurations may not provide the same level of control and security. For instance, using a general service account might grant unnecessary access and permissions that
