Example here is a module for gcloud sql instance, where obviously in production I want to protect it, but more ephemeral environments I want to be able to pull the environment down without editing the code temporarily. Name already in use A tag already exists with the provided branch name. So, a temporary workaround: TL;DR: Use sed to replace the template file and create the target main.tf. Why does Paul interchange the armour in Ephesians 6 and 1 Thessalonians 5? briefly describe the purpose of each variable using the optional can serve as helpful reminders for users of the module, and they Connect and share knowledge within a single location that is structured and easy to search.

This would let me effectively use modules to run dev & test environments with the same config as prod, while providing deletion protection for prod resources. terraform plan -var-file=environments/weu-dev.tfvars "-var=sql_database={"create_environmental": true, "optional_token": "1123444"}". To avoid this error, either declare a variable block for the value, or remove This is of course not as convenient as creating everything in one step using directly-referenced modules, but maybe it's a reasonable workaround for some situations in the mean time. Our modules need to be capable of having lifecycle as variables. For example, at a bash prompt on a Unix system: On operating systems where environment variable names are case-sensitive, bucket = var.backend_bucket_name Sure, this "works", but it is completely against the very purpose of Terraform, which is to declaratively store a complete picture of resources as code. The following fields can be specified in the provider block to further configure the retry behavior: disable_auto_retries - Disable automatic retries for retriable errors.
