Access Google Cloud from HCP Terraform with workload identity

The text discusses the use of workload identity federation as an alternative to storing service account keys for secure access to Google Cloud from HCP Terraform. Workload identity federation uses IAM to grant external identities, such as HCP Terraform, the ability to impersonate service accounts. This method eliminates the need to store long-lived service account keys in HCP Terraform, which poses a significant security risk if compromised. The text provides an example of how to configure workload identity federation in Google Cloud and shares the benefits of using this approach for improved security and scalability within HCP Terraform workspaces.
