Earlier versions of this code allowed "ref" to take any value that would be accepted by "git checkout" as a valid target of a symbolic ref. We inadvertently accepted a breaking change to upstream go-getter that broke that as part of introducing a shallow clone optimization, because shallow clone requires selecting a single branch. To restore the previous capabilities while retaining the "depth" argument, here we accept a compromise where "ref" has the stronger requirement of being a valid named ref in the remote repository if and only if "depth" is set to a value greater than zero. If depth isn't set or is less than one, we will do the old behavior of just cloning all of the refs in the remote repository in full and then switching to refer to the selected branch, tag, or naked commit ID as a separate step. This includes a heuristic to generate an additional error message hint if we get an error from "git clone" and it looks like the user might've been trying to use "depth" and "ref=COMMIT" together. We can't recognize that error accurately because it's only reported as human-oriented git command output, but this heuristic should hopefully minimize situations where we show it inappropriately. For now this is a change in the Terraform repository directly, so that we can expedite the fix to an already-reported regression. After this is released I tend to also submit a similar set of changes to upstream go-getter, at which point we can revert Terraform to using the upstream getter.GitGetter instead of our own local fork. |

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.
