Should I use Terraform workspaces?

Terraform workspaces are a great way to separate resources by stage. For instance, one might have Terraform defining infrastructure across multiple distinct stages (or AWS Accounts) each with their own stage-specific configuration. That is to say that Terraform separates state by workspace.

What happens if you delete Terraform state file?

Terraform will search the state for any instances matching the given resource address, and remove the record of each one so that Terraform will no longer be tracking the corresponding remote objects.

How to create workspaces in TerraForm cloud Kubernetes?

The logic for creating and updating workspaces in Terraform Cloud exists in the terraform-k8s binary.

The controller will check for changes to inline non-sensitive variables, module source, and module version.

How are resources named with variables in TerraForm?

I was fundamentally misunderstanding how modules worked. Terraform does not support interpolation in resource names (see the relevant issues ), but that doesn’t matter in my case, because the resources of each instance of a module are in the instance’s namespace.
