‍Terramate is an open-source IaC orchestration tool for Terraform, OpenTofu, Pulumi, Cloudformation, and others, that streamlines and scales your IaC workflows.

Nice, this looks close to https://terramate.io/ stacks

You might want to take a look at Terramate. Compared to other tooling such as Terragrunt we're not a wrapper that will lock you in yet another syntax. Terramate is a code generator and orchestrator that helps you to generate native Terraform that can be executed in whatever environment of your choice.

Another option for Terragrunt could be Terramate. It comes with Code Generation that helps you to automatically generate files such as Terraform, Provider and Backend configurations in various stacks (directories). The upside is that it always generates native Terraform code.

This can be done with a tool such as Terramate or Terragrunt (afaik Terragrunt doesn't come with change detection).

I'd love to add Terramate to the list of alternatives to Terraform Cloud!

That sounds like something Terramate helps with. I've been using it exactly for that purpose (code generation) and it made everything so much easier!

How can we handle this? Are there any mechanisms to prevent or at least to some extent safeguard this kind of issues without falling back to a manual workflow? There is. One huge advantage of sticking to (de-facto) standards like Terraform is that first we are probably not the first ones to come up with this question and second there is a huge ecosystem around Terraform that might help us with such challenges. And for this specific scenario the solution is the Open Policy Agent. Let us take a closer look how the solution could look like.

A popular Policy-as-Code tool for Terraform is OPA, everyone's favorite versatile open-source policy engine that enforces security and compliance policies across your cloud-native stack, making it easier to manage and maintain consistent policy enforcement in complex, multi-service environments.

Harness Policy As Code uses Open Policy Agent (OPA) as the central service to store and enforce policies for the different entities and processes across the Harness platform. In this section, you will define a policy that will deny a pipeline execution if there is no approval step defined in a deployment stage.

OPA: While OPA is an open-source, general-purpose policy engine capable of enforcing unified and context-aware policies throughout the stack, it can also accept and output data in formats such as JSON, effectively functioning as a tool for generating or modifying configurations. Although it does not provide out-of-the-box schema definition support, it allows the integration of JsonSchema definitions.

In essence, container image signing involves adding a digital stamp to an image, affirming its authenticity. This digital assurance guarantees that the image is unchanged from creation to deployment. In this blog, I'll explain how to sign container images for Kubernetes using Cosign and the Open Policy Agent. I will also share a tutorial that demonstrates these concepts.

In this post we will explores two powerful solutions for addressing this issue: the Open Policy Language (OPA) and Google’s Zanzibar.

Rego is a declarative query language from the makers of the Open Policy Agent (OPA) framework. The Cloud Native Computing Foundation (CNCF) accepted OPA as an incubation-level hosted project in April 2019, and OPA graduated from incubating status in 2021.

Now there are more subdivided practice: * Policy as Code: Sentinel, OPA * Database as Code: bytebase * AppConfiguration as Code: KusionStack, Acorn * ...... (Welcome to add more)
