Pulumi's participation at KubeCon in San Diego featured the release of two technology previews: Pulumi Crosswalk for Kubernetes and Pulumi Query for Kubernetes. Crosswalk offers a set of playbooks with common patterns to simplify Kubernetes API syntax by providing trusted defaults, while Query enhances observability by allowing resource process exposure via batch or streaming queries. Sara Novotny, in a keynote with Liz Fong-Jones, emphasized observability as a system's ability to provide insights. Pulumi engineers Erin Krengel and Sean Holung presented on using ephemeral environments for automated testing, highlighting their utility in mimicking production settings. The CNCF facilitated the rapid availability of presentation videos, allowing broader access to the insights shared at the event. Pulumi expressed enthusiasm for future participation at KubeCon 2020.
