How do I enforce policy-as-code for DNS using OPA and Conftest?

Enforcing policy-as-code for DNS using Open Policy Agent (OPA) and Conftest is a powerful method to ensure compliance and governance in your infrastructure. This guide explains how to integrate OPA with Conftest to validate DNS configurations against defined policies, facilitating a robust DevOps practice.


        package dns

        default allow = false

        # Policy to allow only specific DNS record types
        allow {
            input.record_type == "A" 
        } else { 
            input.record_type == "CNAME" 
        } else {
            input.record_type == "TXT"
        }

        # Policy to enforce naming conventions
        valid_record_name(record_name) {
            count(record_name) >= 3 
        }
