Pulumi has introduced support for the Open Policy Agent (OPA) Rego language in its CrossGuard policy-as-code framework, allowing users to write policies in either JavaScript, TypeScript, Python, or Rego. This integration broadens the spectrum of policy authoring options, enabling users to leverage the declarative Rego language for creating and enforcing policies across Pulumi deployments in various environments, including cloud and Kubernetes. The CrossGuard framework supports policy enforcement during deployment previews, ensuring policy violations are detected early, and offers both advisory and mandatory recommendations. This allows organizations to maintain high standards of compliance, security, and best practices across their infrastructure projects. With the addition of OPA, Pulumi now offers a versatile platform for authoring and enforcing infrastructure policies, catering to diverse infrastructure teams' needs by supporting multiple programming languages. Integration with tools like Visual Studio Code enhances the development experience, making it easier to manage infrastructure and policies within a comprehensive IDE environment.
