Conftest is a utility that allows users to write tests against structured configuration data, such as Kubernetes YAMLs, Terraform code, or Serverless configurations. It uses the Rego language from Open Policy Agent to define and evaluate policies.

Who can benefit from using Conftest?

Conftest is beneficial for developers, DevOps engineers, and platform teams who need to enforce standards, best practices, or security policies across their configuration files. It helps maintain consistency and prevent misconfigurations in infrastructure-as-code and application deployments.

How does Conftest handle policy enforcement?

Conftest uses the Rego policy language from Open Policy Agent, offering a powerful and flexible way to define complex validation rules. It allows for the creation of custom policies that can enforce a wide range of organizational standards and security requirements.

When should I use Conftest in my development workflow?

Conftest should be integrated early in the development lifecycle, typically as part of pre-commit hooks or CI/CD pipelines, to validate configuration files. This ensures configurations adhere to defined policies before they are committed or deployed, catching issues proactively.

What types of configuration files does Conftest support?

Conftest supports a wide array of structured configuration data formats, including YAML, JSON, HCL, Dockerfile, INI, TOML, and more. Policies are written in Rego, which allows for robust validation logic across these various formats.
