It's not about terraform handling it or not, it's about ensuring that drift is automatically corrected without a CI trigger. One of the core principles of GitOps is continuous reconciliation. This requires a reconciliation loop, e.g. some task that runs automatically and without user intervention. As far as I can tell from their docs Digger only runs its steps on a pull request, similar to Atlantis (but "without the backend"). This is continuous delivery, but it's not continuous reconciliation, and therefore not GitOps. GitOps would be something like combining Flux or ArgoCD with Crossplane.

think i'm going to take the feedback from this discussion to the opengitops working group tomorrow, hoping we can maybe get it defined in their vendor agnostic gitops glossary https://github.com/open-gitops/documents/blob/main/GLOSSARY.md haha, which i'm sure chatgpt will figure out about like 12 seconds later, consider correct, and then just wire the architecture together for us. but we can just start with kubefirst while chatgpt is trying to catch up haha.

The GitOps term was coined back in 2017 by Weaveworks, and paraphrasing OpenGitOps, a GitOps system is based on the following principles:

That's why there's systems for continuous reconciliation. I'ts one of the four fundamental principles of GitOps.

In 2021, the first OpenGitOps Standard v1 was created, to make sure we all GitOps enthusiasts speak the same language. For more information go to opengitops.dev.

The working group has been hard at work, over many meetings, github discussions, revisions, blood, sweat, and tears we've just merged the pre-release GitOps Principles and glossary. Check them out here and be sure to make issues/comments. It'd be great to hear everyone's thoughts.

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.

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.

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.

Alternatively, you can look at solutions like Atlantis or spacelift.

Looking at the commits at https://github.com/runatlantis/atlantis, it looks like 1.6.5. Am I right?

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.
