Some of our warnings are produced in response to particular configuration constructs which might appear many times across a Terraform configuration. To avoid the warning output dwarfing all of the other output, we'll use ConsolidateWarnings to limit each distinct warning summary to appear at most twice, and annotate the final one in the sequence with an additional paragraph noting that some number of them have been hidden. This is intended as a compromise to ensure that these warnings are still seen and noted but to help ensure that we won't produce so many of them as to distract from other output that appears alongside them. This applies only to warnings relating to specific configuration ranges; errors will continue to be shown individually, and sourceless warnings (which are rare in Terraform today) will likewise remain ungrouped because they are less likely to be repeating the same statement about different instances of the same problem throughout the configuration. |

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.
