They seem very insistent on keeping things DRY but not explaining why. Does Terraform tend to cause water leaks?

  Terraform is supposed to let you write modular, reusable code. But because it's a limited DSL that lacks many "proper language" features (and occasionally breaks the rule of least-suprise). There are several major impediments to fully data-driven terraform. These ultimately result in copy/paste code, or tools like terragrunt which essentially wrap terraform and perform the copy/pasta behind your back by generating that code for you. Some minor examples: - calling a module multiple times using `for_each` to iterate over data works, except if the module contains a "provider" block - if you are deploying two sets of resources by iterating over data, terraform can detect dependency cycles where there are not any
