Previously the templatefile function would permit any arbitrary string as a variable name, but due to the HCL template syntax it would be impossible to refer to one that isn't a valid HCL identifier without causing an HCL syntax error. The HCL syntax errors are correct, but don't really point to the root cause of the problem. Instead, we'll pre-verify that the variable names are valid before we even try to render the template, and given a specialized error message that refers to the vars argument expression as the problematic part, which will hopefully make the resolution path clearer for a user encountering this situation. The syntax error still remains for situations where all of the variable names are correct but e.g. the user made a typo referring to one, which makes sense because in that case the problem _is_ inside the template. |

Terraform
- Website: https://www.terraform.io
- Forums: HashiCorp Discuss
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.
