Previously we had a separation between ModuleSourceRemote and ModulePackage as a way to represent within the type system that there's an important difference between a module source address and a package address, because module packages often contain multiple modules and so a ModuleSourceRemote combines a ModulePackage with a subdirectory to represent one specific module. This commit applies that same strategy to ModuleSourceRegistry, creating a new type ModuleRegistryPackage to represent the different sort of package that we use for registry modules. Again, the main goal here is to try to reflect the conceptual modelling more directly in the type system so that we can more easily verify that uses of these different address types are correct. To make use of that, I've also lightly reworked initwd's module installer to use addrs.ModuleRegistryPackage directly, instead of a string representation thereof. This was in response to some earlier commits where I found myself accidentally mixing up package addresses and source addresses in the installRegistryModule method; with this new organization those bugs would've been caught at compile time, rather than only at unit and integration testing time. While in the area anyway, I also took this opportunity to fix some historical confusing names of fields in initwd.ModuleInstaller, to be clearer that they are only for registry packages and not for all module source address types. |

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
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.
