This makes the built-in "remote-exec" and "file" provisioners available for use in the modules that implement stack components. These are both relatively easy and low-risk to include because they are builtins and don't require anything from outside of Terraform itself. For now this intentionally excludes local-exec because we'll want to think about what constraints we want to put on it, if any, to help ensure we can meet the goal of stack configurations being portable between different execution environments without significant modification, and our current stacks execution environment doesn't guarantee the availability of any external software _at all_. The motivation for adding this now is just to give some better feedback when someone uses a module using one of these provisioners, since otherwise they'll see just a confusing generic error message from the modules runtime about the provisioners not being available. I expect we'll revisit this later and consider expanding it to at least include local-exec, and _maybe_ external provisioner plugins, although that's more questionable because the provisioner plugin mechanism is incredibly legacy and doesn't have any way to work outside of local Terraform CLI usage today. There are no tests here yet because these provisioners are not mockable and would depend on having an SSH or WinRM server to connect to. Later we should ponder how to make this more testable, which might mean making another part of the system responsible for actually providing the provisioner factories and thus our tests here can use fakes. The goal here is just to get this done in a relatively lightweight way for better feedback during preview though, so we're not yet ready to make significant time investments here. |

Terraform

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.
