Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Top Terraform Tools to Know in 2024
Terraformer is a CLI tool developed by Google that generates Terraform files from existing infrastructure (reverse Terraform), simplifying the process of adopting Terraform in existing environments and speeding up the initial setup process. Terraformer supports multiple cloud providers, including AWS, Google Cloud, Azure, and others.

Terraformer + refactoring with 'moved' blocks
Looking into efficient ways to import existing infrastructure. Using Terraformer to get the everything into Terraform and then refactoring into modules, for_each, etc. using moved blocks seems like it would be a good approach. Refactoring them to use existing modules from providers will take a little work and likely going back and forth with terraform plan, and assuming many things won't translate straight across because of what resources a module might be creating and how they are creating them.

The Future of Terraform: ClickOps
We had thought about the ability to convert HCL to Go, but not much thought in querying existing infra to generate HCL (like terraformer). If you want to experiment building on top of Lingon then please go ahead! I’d be happy to help provide the context from Lingon.
-
How do you glue Terraform resources together?
If "ClickOps" is your starting point, as you mention, you could try creating a new scratch cloud provider account, do all your "ClickOps", then use a TF export tool (e.g., Terraformer) to see the exported TF resources to find all the references to other TF resources in the cloud resource dependency chain.

Strategies for converting an existing deployment to IaC?
I haven't worked with any of the ones that purport to work with AWS, but a quick Google shows terraformer and Terracognita as options - maybe look into trying those out?
-
Migration to gcp from aws.
This maybe a bit more complicated if you're not into coding/terraform but I'd use terraformer to convert all of your infrastructure from implementation to code while in AWS, then switch providers and with a bit of jiggly of the code implement your infra into gcs as IaC and keep it that way if/when you switch again.

Quick terraform noob question about the tfstate
Maybe terraformer could help. I never tried it personally . https://github.com/GoogleCloudPlatform/terraformer

How do I convert my CloudFormation template into a Terraform file?
I've been wondering if this tool is any good. https://github.com/GoogleCloudPlatform/terraformer/blob/master/docs/aws.md

Migrate from terragrunt to terraform
If you've to write the code (I assumed you just needed to reorganize it without TG) maybe consider https://github.com/GoogleCloudPlatform/terraformer

OpenTofu 1.7.0 is out with State Encryption, Dynamic Provider-defined Functions
None of these are a replacement of Terraform Cloud (recently rebranded to HCP Terraform). For example, when you create a PR, it could affect multiple workspaces. The new experimental version of TFC/TFE (I refuse to call it HCP!) implements Stacks, which is something like a workflow, and links one workspace output to other workspace inputs. None of the open-source solutions, including the paid Digger [0], support this - only the paid one, such as Spacelift [1] (which is the closest to TFC if you ask me). Having a monorepo of Terraform is a common design pattern, so, if I change an embedded module, it could trigger changes it many workspaces. As far as I know, Atlantis [2] can't really help in this case.
By the way, the reason I singled-out Spacelift is due to its quality, and the great Terraform provider it has. Scalr [3], for example, has a really low-quality Terraform provider. I extensively use the hashicorp/tfe provider to manage TFC itself.

Terramate meets Atlantis 🚀
Atlantis is a pull request automation tool that works well with plain Terraform right away. But what if we're already using Terramate to generate Terraform code?

Atlantis automates reviewing and deploying Terraform via pull requests, streamlining collaboration and ensuring consistency across Terraform deployments.

Stop Squinting at IaC Templates: Preview Diffs for Argo CD, Terraform, and more!
For example, Atlantisgo for Terraform, Zapier’s Kubechecks for Argo CD, Quizlet’s GitHub action all do something similar to this. But a generic, extensible tool for IaC providers doesn’t seem to exist. Additionally, many of them require exposing your Kubernetes cluster or other infrastructure to third-party access, webhooks, etc.

Self-service infrastructure as code
Our first attempt was to introduce other engineering teams to Terraform - the Platform team was already using it extensively with Terragrunt, and using Atlantis to automate plan and apply operations in a Git flow to ensure infrastructure was consistent. We'd written modules, with documentation, and an engineer would simply need to raise a PR to use the module and provide the right values, and Atlantis (once the PR was approved by Platform) would go ahead and set it up for them.

Version of terraform binary cli does it include in the container
Looking at the commits at https://github.com/runatlantis/atlantis, it looks like 1.6.5. Am I right?

Terraform Cloud Pricing Changes Sticker Shock
We use Atlantis [0] for CI/CD automation of Terraform pull requests to a centralized repository. It's pretty good too, especially for a self-hosted solution. I can't see how Terraform Cloud's costs would be justifiable for us without a custom contract.
