Nick Fagerlund 9b449bec99 Sort dependencies when encoding ResourceInstanceObject
Resource dependencies are by nature an unordered collection, but they're
persisted to state as a JSON array (in random order). This makes a mess for
`terraform apply -refresh-only`, which sees the new random order as a change
that requires the user to approve a state update.

(As an additional problem on top of that, the user interface for refresh-only
runs doesn't expect to see that as a type of change, so it says "no changes!
would you like to update to reflect these detected changes?")

This commit changes `ResourceInstanceObject.Encode()` to sort the in-memory
slice of dependencies (lexically, by address) before passing it on to be
compared and persisted. This appears to fix the observed UI issues with a
minimum of logic changes.

Terraform

Terraform

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.

To learn more about compiling Terraform and contributing suggested changes, please refer to the contributing guide.

To learn more about how we handle bug reports, please read the bug triage guide.
