terraform-controller VS gitops-playground

In addition to creating Kubernetes clusters, there is also an increasing number of opportunities to use various Infrastructure-as-Code (IaC) tools, such as Terraform, with GitOps. As was already mentioned, PipeCD offers support for Terraform. Terraform's vendor, HashiCorp, now also offers an official Terraform Kubernetes operator. However, it needs access to HashiCorp's Terraform Cloud. Alternatively, there are also third-party operators that can function without Terraform Cloud, such as the one developed by Rancher. However, it is still in alpha stage.

Flux has certain little features that ArgoCD doesn't have, such as support for SOPS and automatic updates for new image versions. However, the latter is the reasons that Flux v2 has not yet appeared in a stable version. It could be difficult to opt for a product with a version number 0.x when it is the central component in the supply chain. However, we do expect the release of a stable version here soon. One possibility to see ArgoCD and Flux v2 in action and compare their features is the GitOps Playground project that was started by the authors.
