Sample terraform plan data the policy should work against. The Open Policy Agent (OPA) is an open source, general-purpose policy engine that enables unified, context-aware policy enforcement across the entire stack. OPA makes it possible to write policies that test the changes Terraform is about to make before it makes them. If you are thinking only about one of your service or for all your services in the complete stack, One can use OPA to decouple policy from the service’s code so you can release, analyze, and review policies without compromising availability or performance of your infrastructure. Contributions welcome! # Get the whole response: # opa eval --data terraform-cost-estimation.rego --input terraform.tfstate --format pretty data.terraform_cost_estimation # Get boolean response. You can read more about Rego in How do I write policies in the Open Policy Agent documentation. This repository contains the code for the blog post here: https: . You learned a number of things about Terraform Testing with OPA: Keep in mind that it’s up to you to decide how to use OPA’s Terraform tests and authorization decision. It is easy to understand and should be relatively simple to learn. We use these as part of the project I am working on, but the examples are not specific to the project. Although one can also write his manual policy checking .rego file. Terraform lets you describe the infrastructure you want and automatically creates, deletes, and modifies your existing infrastructure to match. Usage of OPA can be done as a unified toolset and framework for policy across the cloud native stack. This json file is a very complicated, nested structure with . EC2 data to OPA and write policy using all of that context. Furthermore we have the concept of Infrastructure As Code which is a well-defined process of management and provisioning cloud based systems or such infrastructures through declarative configuration files, rather than physical hardware configuration or some other configuration management tools. In this article. Here is the expected contents of tfplan.json. (You will need to modify the shared_credentials_file What Terraform did for infrastructure automation, OPA is doing for policy automation. Validating Terraform plans using the Open Policy Agent Requirements Generating a terraform plan Evaluating the plan Unit testing Rego policies.
