For many features being developed, we want our devs to spin up their own infrastructure that will persist only for the length of time their feature branch exists to me, the best way to do that would be to use the name of the branch to create the key for the path used to store the tfstate (we're using amazon infrastructure, so in our case, the s3 bucket like the examples above). to your account, Variables are used to configure the backend. from the perspective of the user of the module rather than its maintainer. variable "aad_allowed_tenants" { A sensitive variable is a configuration-centered concept, and values are sent to providers without any obfuscation.

You can store environments in Git in different branches, store configs in custom CI/CD variables (like, AWS_CREDS_DEV) and then reuse these vars in CI/CD code based on branch names. By the time plan is running, Terraform is just thinking about the module name and paying no attention to the module source, since the module is assumed to already be retrieved into the .terraform subdirectory.
