A significant goal of the design changes around checks in earlier commits (with the introduction of package "checks") was to allow us to differentiate between a configuration object that we didn't expand at all due to an upstream error, which has _unknown_ check status, and a configuration object that expanded to zero dynamic objects, which therefore has a _passing_ check status. However, our initial lowering of checks.State into states.CheckResults stayed with the older model of just recording each leaf check in isolation, without any tracking of the containers. This commit therefore lightly reworks our representation of check results in the state and plan with two main goals: - The results are grouped by the static configuration object they came from, and we capture an aggregate status for each of those so that we can differentiate an unknown aggregate result from a passing aggregate result which has zero dynamic associated objects. - The granularity of results is whole checkable objects rather than individual checks, because checkable objects have durable addresses between runs, but individual checks for an object are more of a syntactic convenience to make it easier for module authors to declare many independent conditions that each have their own error messages. Since v1.2 exposed some details of our checks model into the JSON plan output there are some unanswered questions here about how we can shift to reporting in the two-level heirarchy described above. For now I've preserved structural compatibility but not semantic compatibility: any parser that was written against that format should still function but will now see fewer results. We'll revisit this in a later commit and consider other structures and what to do about our compatibility constraint on the v1.2 structure. Otherwise though, this is an internal-only change which preserves all of the existing main behaviors of conditions as before, and just gets us ready to build user-facing features in terms of this new structure. |

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, refer to the What is Terraform? page on the Terraform website.
Getting Started & Documentation
Documentation is available on the Terraform website:
If you're new to Terraform and want to get started creating infrastructure, please check out our Getting Started guides on HashiCorp's learning platform. There are also additional guides to continue your learning.
Show off your Terraform knowledge by passing a certification exam. Visit the certification page for information about exams and find study materials on HashiCorp's learning platform.
Developing Terraform
This repository contains only Terraform core, which includes the command line interface and the main graph engine. Providers are implemented as plugins, and Terraform can automatically download providers that are published on the Terraform Registry. HashiCorp develops some providers, and others are developed by other organizations. For more information, see Extending Terraform.
