The clistate package includes a Locker interface which provides a simple way for the local backend to lock and unlock state, while providing feedback to the user if there is a delay while waiting for the lock. Prior to this commit, the backend was responsible for initializing the Locker, passing through direct access to the cli.Ui instance. This structure prevented commands from implementing different implementations of the state locker UI. In this commit, we: - Move the responsibility of creating the appropriate Locker to the source of the Operation; - Add the ability to set the context for a Locker via a WithContext method; - Replace the Locker's cli.Ui and Colorize members with a StateLocker view; - Implement views.StateLocker for human-readable UI; - Update the Locker interface to return detailed diagnostics instead of errors, reducing its direct interactions with UI; - Add a Timeout() method on Locker to allow the remote backend to continue to misuse the -lock-timeout flag to cancel pending runs. When an Operation is created, the StateLocker field must now be populated with an implementation of Locker. For situations where locking is disabled, this can be a no-op locker. This change has no significant effect on the operation of Terraform, with the exception of slightly different formatting of errors when state locking or unlocking fails. |

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.
