atlantis VS werf

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.

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.

I am looking as well for this kind of tool. I just took a look today by exploring the CNCF landscape this tool : https://werf.io/ , I haven't used it, but it seems to take care of painful stuff like automatic versioning for example. (If someone here tried it, I will be happy to listen to your feedbacks)

Check out https://werf.io/ tool. It features giterminism which is somewhat similar to gitops, but it does not require pull model. Giterminism aims to improve reproducibility of your build and deploy configuration. werf also features content-based-tagging out of the box, which allows creating immutable images, stored in the container-registry, shared between multiple runners (werf uses distributed locking to prevent overriding image which is already published). Giterminism and content-based-tagging enables easy rollbacks to any git-commit in the history of your project. By design werf could be embedded into any ci/cd system.

Rename of dapp to werf was in Jan'19 to be precise (https://github.com/werf/werf/pull/1213).

Werf

You can try werf, it has Helm under the hood and there are github actions available for it: https://github.com/werf/actions

As you know, there's plenty of tools that can be used to build your Docker images, besides the docker build itself. werf is an Open Source project with a long history (started in 2016 as a simple wrapper around Docker CLI). Still being a CLI tool, today it is focused not just on the building but also delivering these images to Kubernetes — and this is what makes it really different.
