As we continue iterating towards saving valid hashes for a package in a depsfile lock file after installation and verifying them on future installation, this prepares getproviders for the possibility of having multiple valid hashes per package. This will arise in future commits for two reasons: - We will need to support both the legacy "zip hash" hashing scheme and the new-style content-based hashing scheme because currently the registry protocol is only able to produce the legacy scheme, but our other installation sources prefer the content-based scheme. Therefore packages will typically have a mixture of hashes of both types. - Installing from an upstream registry will save the hashes for the packages across all supported platforms, rather than just the current platform, and we'll consider all of those valid for future installation if we see both successful matching of the current platform checksum and a signature verification for the checksums file as a whole. This also includes some more preparation for the second case above in that signatureAuthentication now supports AcceptableHashes and returns all of the zip-based hashes it can find in the checksums file. This is a bit of an abstraction leak because previously that authenticator considered its "document" to just be opaque bytes, but we want to make sure that we can only end up trusting _all_ of the hashes if we've verified that the document is signed. Hopefully we'll make this better in a future commit with some refactoring, but that's deferred for now in order to minimize disruption to existing codepaths while we work towards a provider locking MVP. |

Terraform
- Website: https://www.terraform.io
- Forums: HashiCorp Discuss
- Documentation: https://www.terraform.io/docs/
- Tutorials: HashiCorp's Learn Platform
- Certification Exam: HashiCorp Certified: Terraform Associate
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.
