Martin Atkins 8405f46bc5 tfdiags: Expose the "extra information" concept from HCL
HCL's diagnostic model now includes the idea of "extra information" which
works by attaching an initially-opaque interface value to each diagnostic
and then asking callers to type-assert against that value to sniff for
particular interfaces in order to discover additional machine-readable
context about a certain diagnostic message.

This commit echoes that idea into our tfdiags API, for now only for
diagnostics that are backed by an hcl.Diagnostic. All other implementations
of the diagnostic interface just always return nil, which means they never
carry any "extra information".

As is typical for our wrapping abstraction, we have here also a modified
copy of HCL's helper function for conveniently probing a diagnostic for
information of a particular type, designed to work with our diagnostic
interface instead of HCL's concrete diagnostic type.

Terraform

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, 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.

To learn more about compiling Terraform and contributing suggested changes, please refer to the contributing guide.

To learn more about how we handle bug reports, please read the bug triage guide.
