Pulumi Kubernetes Operator v2.3.0: Preview Mode and Structured Configuration

Pulumi has released version 2.3.0 of its Kubernetes Operator, introducing significant features that enhance GitOps workflows, namely the preview mode and structured configuration support. Preview mode allows users to validate infrastructure changes in a dry-run fashion before deployment, facilitating safer and more sophisticated management patterns, such as what-if analyses and branch validations. The structured configuration feature supports complex data types like objects and arrays, previously limited to string values, allowing for richer configuration management. This update addresses longstanding community requests while maintaining full backwards compatibility and includes several bug fixes to improve operational reliability. The release requires updates to Custom Resource Definitions (CRDs) for users employing Helm, with guidance provided for seamless upgrading, and emphasizes the need for Pulumi CLI version 3.202.0 or later to fully utilize structured configuration support.
