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

In the realm of DevOps, enforcing policies for API versioning is essential for maintaining a robust and scalable infrastructure. By integrating Open Policy Agent (OPA) and Conftest, teams can implement policy-as-code that automates compliance checks for API versions throughout the development cycle.

This approach fosters better governance, ensuring that only APIs meeting predefined criteria are deployed. Below, we demonstrate how to create a policy that checks for API versioning rules using OPA and Conftest.

package api_versioning violation[{"msg": msg}] { input.api_version < "1.0.0" msg := "API version must be at least 1.0.0" } violation[{"msg": msg}] { input.api_version > "2.0.0" msg := "API version must not exceed 2.0.0" }
