Our model for plans/planfile has unfortunately grown inconsistent with changes to our modeling of plans.Plan. Originally we considered the plan "header" and the planned changes as an entirely separate artifact from the prior state, but we later realized that carrying the prior state around with the plan is important to ensuring we always have enough context to faithfully render a plan to the user, and so we added the prior state as a field of plans.Plan. More recently we've also added the "previous run state" to plans.Plan for similar reasons. Unfortunately as a result of that modeling drift our ReadPlan method was silently producing an incomplete plans.Plan object, causing use-cases like "terraform show" to produce slightly different results due to the plan object not round-tripping completely. As a short-term tactical fix, here we add state snapshot reading into the ReadPlan function. This is not an ideal solution because it means that in the case of applying a plan, where we really do need access to the state _file_, we'll end up reading the prior state file twice. However, the goal here is only to heal the modelling quirk with as little change as possible, because we're not currently at a point where we'd be willing to risk regressions from a larger refactoring. |

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.
