The SearchLocalDirectory function was intentionally written to only support symlinks at the leaves so that it wouldn't risk getting into an infinite loop traversing intermediate symlinks, but that rule was also applying to the base directory itself. It's pretty reasonable to put your local plugins in some location Terraform wouldn't normally search (e.g. because you want to get them from a shared filesystem mounted somewhere) and creating a symlink from one of the locations Terraform _does_ search is a convenient way to help Terraform find those without going all in on the explicit provider installation methods configuration that is intended for more complicated situations. To allow for that, here we make a special exception for the base directory, resolving that first before we do any directory walking. In order to help with debugging a situation where there are for some reason symlinks at intermediate levels inside the search tree, we also now emit a WARN log line in that case to be explicit that symlinks are not supported there and to hint to put the symlink at the top-level if you want to use symlinks at all. (The support for symlinks at the deepest level of search is not mentioned in this message because we allow it primarily for our own cache linking behavior.) |

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 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.
