Optional Terraform Blocks

Since Terraform 0.12.0 there are arguments and blocks; just two ways of configuring resources. “An argument assigns a value to a particular name” and a “block is a container for other content” (source). Not a very enlightening definition, but after all “just” syntax anyway. Don’t get me wrong, syntax (and therefore UX) is one of the most important aspects of technology in my point of view.

Given some blocks may need to be repeated, Terraform has a way of making them dynamic. Great, but what if Terraform you want to make them optional?
