Terraform 0.12.0 removed the need for putting references and keywords in quotes, but we disabled the deprecation warnings for the initial release in order to avoid creating noise for folks who were intentionally attempting to maintain modules that were cross-compatible with both Terraform 0.11 and Terraform 0.12. However, with Terraform 0.12 now more widely used, the lack of these warnings seems to be causing newcomers to copy the quoted versions from existing examples on the internet, which is perpetuating the old and confusing quoted form in newer configurations. In preparation for phasing out these deprecated forms altogether in a future major release, and for the shorter-term benefit of giving better feedback to newcomers when they are learning from outdated examples, we'll now re-enable those deprecation warnings, and be explicit that the old forms are intended for removal in a future release. In order to properly test this, we establish a new set of test configurations that explicitly mark which warnings they are expecting and verify that they do indeed produce those expected warnings. We also verify that the "success" tests do _not_ produce warnings, while removing the ones that were previously written to succeed but have their warnings ignored. |

Terraform
- Website: https://www.terraform.io
- Mailing list: Google Groups
Terraform is a tool for building, changing, and versioning infrastructure safely and efficiently. Terraform can manage existing and popular service providers as well as custom in-house solutions.
The key features of Terraform are:
-
Infrastructure as Code: Infrastructure is described using a high-level configuration syntax. This allows a blueprint of your datacenter to be versioned and treated as you would any other code. Additionally, infrastructure can be shared and re-used.
-
Execution Plans: Terraform has a "planning" step where it generates an execution plan. The execution plan shows what Terraform will do when you call apply. This lets you avoid any surprises when Terraform manipulates infrastructure.
-
Resource Graph: Terraform builds a graph of all your resources, and parallelizes the creation and modification of any non-dependent resources. Because of this, Terraform builds infrastructure as efficiently as possible, and operators get insight into dependencies in their infrastructure.
-
Change Automation: Complex changesets can be applied to your infrastructure with minimal human interaction. With the previously mentioned execution plan and resource graph, you know exactly what Terraform will change and in what order, avoiding many possible human errors.
For more information, see the introduction section of the Terraform website.
Getting Started & Documentation
If you're new to Terraform and want to get started creating infrastructure, please checkout our Getting Started guide, available on the Terraform website.
All documentation is available on the Terraform website:
Developing Terraform
This repository contains only Terraform core, which includes the command line interface and the main graph engine. Providers are implemented as plugins that each have their own repository in the terraform-providers organization on GitHub. Instructions for developing each provider are in the associated README file. For more information, see the provider development overview.
To learn more about compiling Terraform and contributing suggested changes, please refer to the contributing guide.
