This implies some notable changes that will have a visible impact to end-users of official Terraform releases: - Terraform is no longer compatible with MacOS 10.10 Yosemite, and requires at least 10.11 El Capitan. (Relatedly, Go 1.14 is planned to be the last release to support El Capitan, so while that remains supported for now, it's notable that Terraform 0.13 is likely to be the last major release of Terraform supporting it, with 0.14 likely to further require MacOS 10.12 Sierra.) - Terraform is no longer compatible with FreeBSD 10.x, which has reached end-of-life. Terraform now requires FreeBSD 11.2 or later. - Terraform now supports TLS 1.3 when it makes connections to remote services such as backends and module registries. Although TLS 1.3 is backward-compatible in principle, some legacy systems reportedly work incorrectly when attempting to negotiate it. (This change does not affect outgoing requests made by provider plugins, though they will see a similar change in behavior once built with Go 1.13 or later.) - Ed25519 certificates are now supported for TLS 1.2 and 1.3 connections. - On UNIX systems where "use-vc" is set in resolv.conf, TCP will now be used for DNS resolution. This is unlikely to cause issues in practice because a system set up in this way can presumably already reach its nameservers over TCP (or else other applications would misbehave), but could potentially lead to lookup failures in unusual situations where a system only runs Terraform, has historically had "use-vc" in its configuration, but yet is blocked from reaching its configured nameservers over TCP. - Some parts of Terraform now support Unicode 12.0 when working with strings. However, notably the Terraform Language itself continues to use the text segmentation tables from Unicode 9.0, which means it lacks up-to-date support for recognizing modern emoji combining forms as single characters. (We may wish to upgrade the text segmentation tables to Unicode 12.0 tables in a later commit, to restore consistency.) This also includes some changes to the contents of "vendor", and particularly to the format of vendor/modules.txt, per the changes to vendoring in the Go 1.14 toolchain. This new syntax is activated by the specification of "go 1.14" in the go.mod file. Finally, the exact format of error messages from the net/http library has changed since Go 1.12, and so a couple of our tests needed updates to their expected error messages to match that. |

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.

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.
