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

To enforce policy-as-code for GitLab CI using Open Policy Agent (OPA) and Conftest, you can integrate these tools into your CI/CD pipeline to validate configuration files against predefined policies. This ensures that your deployments comply with organizational policies and security standards.

Here’s a basic example of how you can set this up:


        # GitLab CI Configuration
        stages:
          - test
        
        validate:
          stage: test
          script:
            - conftest test your-config-file.yaml
            - echo "Validation successful!"
