Our initial Terraform 0.13.0 release will continue to support only the hard-coded official HashiCorp signing key, with support for other keys to follow in a later release once the trust infrastructure is in place to support that. This change is intended to (marginally) improve the UX for a possible future situation where a HashiCorp-distributed provider makes a released signed with a new key and a prior version of Terraform ends up trying to install it due to incorrect version constraints. With this new text we hope to give the user a better prompt for onward troubleshooting, but in a sort of hedging way because we have not yet finalized the details of how new keys might roll out in practice. Hopefully a user seeing this message would consult the release notes for Terraform itself and for the provider in question and find some as-yet-undetermined information about how to proceed. If the decentralized trust model design comes together before the v0.13.0 release then we may make further amendments here to prepare for that, but that work should not block the v0.13.0 release if other work concludes first. |

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.
