For example, a provider might return the following error even if "foo" is a sensitive value: "Invalid value 'foo' for field".

A use I see easily popping up (in that literally my first project that I'm working on terraform with), I want to have multiple modules that I pull from, but I will always want those to use same branch, within a project: which seems pretty reasonable to me - when I pass in git_tag=prod_git_tag, now they all reference the same git_tag and can be updated with one line, rather than in all the various places. One very specific complexity with this is that currently modules need to be pre-fetched using terraform get prior to terraform plan, and currently that command does not take any arguments that would allow you to set variables. null value as a module input argument will override any default value. the plan or apply output, when you use that variable elsewhere in your We use this http://bensnape.com/2016/01/14/terraform-design-patterns-the-terrafile/ I think it would be reasonable to have something like that natively.

I've got a variable declared in my variables.tf like this: This error can also occurs when trying to setup a variable's value from a dynamic resource (e.g: an output from a child module): Using locals block instead of the variable will solve this issue: I had the same error, but in my case I forgot to enclose variable values inside quotes (" ") in my terraform.tfvars file. description argument: The description should concisely explain the purpose } Because when I try doing the same like this: Create a file named backend.tfvars with content: Specify this file name in a command line option to the terraform command: The reason you need to use a separate backend config file instead of your usual tfvars file is that these values are used when you set up your backend. Terraform will perform the following actions: Plan: 1 to add, 0 to change, 0 to destroy. values behave the same way as other variables: the last value found overrides If employer doesn't have physical address, what is the minimum information I should have from them? I'm hitting this, too. The rationale to disallow this so that intelligent people can't download random modules is the same as not having a division operator as somebody may decide to divide by zero one day. You can specify custom validation rules for a particular variable by adding a validation block within the corresponding variable block. pretty ugly :-). When may be expected if it IS on the roadmap. This is a change from previous versions of Terraform, which It would be nice to understand why this can't work.

It's over 4 years since #3116 was opened, I think we'd all appreciate some indication of where this is? If you're familiar with traditional programming languages, it can be useful to compare Terraform modules to function . recommend always setting complex variable values via variable definitions files. Frankly it's nuts this hasn't been addressed yet. key = "terraform/state/ops-com" This tutorial also appears in: Associate Tutorials (003). I'm going to keep this tagged with "thinking".

Our powershell wrapper does so many things to over come terraform restrictions, we cant use terraform without, basically we did something like the guys in terragrunt did, plus many more addons on it, i cant understand how somebody can even use terraform as is out of the box without some interpolation in those missing places.. anyhow, i really hope hashicorp will decide to change some parts of the product, because it is really constricting, some of those things should have been thought of much before.
