When things are improperly configured or actions within terraform fail. However, I want to store the state of that new project and all config in a gcs bucket in We explored terraform workspaces, and we werent happy to one backend for multiple projects, for multiple reasons, but one was security reasons. The backend configuration determines where and how Warning: We recommend using environment variables to supply credentials and other sensitive data. # Create Problem: You're trying to use variables directly within blocks like terraform { backend {} }. hcl. It just doesn’t support it. All values must be expressed as an HCL literal in the same syntax you would use when writing Hi all, Terraform cannot support arbitrary expressions in the backend block because the configuration inside it must be processed to even retrieve the latest state snapshot, and the gcs/ This example sets up a GCS backend with a minimal example of a state stored in it. This blog explores Terraform backends, their types, and configuration for cloud providers like AWS, Azure, and GCP. Use the `backend` block to control where Terraform stores state.

As of Terraform v1. It: Creates an GCS bucket with a random name (‘changeme-xxxxxxxxxxxxx’) Sets up an GCP I have three GCP projects let's say project-01, project-02 and project-03 and I'm trying to create Compute Instance in those respective projects using single terraform module. Variables may not be used here Terraform is telling you that it does not allow prevent_destroy to contain variables. Now that we have "environments" in terraform, I was hoping to have a single config.
