Pulumi has been deeply integrated with Kubernetes since its inception, offering comprehensive support across all versions of the Kubernetes API, and now Pulumi is releasing Kubernetes 4.0, which includes enhancements like default Server-Side Apply, upserting on all resources, and new Patch resources. The update simplifies access to outputs in various SDKs, supports Kubernetes clusters version 1.13 or newer, and enhances the diff process to detect resource drift more efficiently. These improvements make Pulumi's platform more native to Kubernetes, allowing for flexible resource management and integration with Pulumi's infrastructure-as-code model in popular programming languages. The release aims to streamline the management of Kubernetes resources even when they are modified by external systems, and Pulumi's new features facilitate safer multi-controller management and more precise updates to shared resources. Users can migrate to Kubernetes 4.0, benefit from improved performance for larger stacks, and take advantage of the free on-demand webinar offered by Pulumi and the CNCF to explore these advancements and build internal developer platforms.
