CoreWeave adds comprehensive Node Pool configuration management with staged updates, rollback support, and full configuration history visibility. Users can now track active and pending configurations and use cwic to upgrade Node Pools or roll back to earlier states.
CKS Node Pools now support comprehensive configuration management with staged updates, rollback capabilities, and full visibility into configuration history.
Node Pool configurations define the desired state for Nodes, including ncore image, GPU driver, and Kubernetes versions. The Node Pool Status now tracks the active configuration, staged pending configurations awaiting user approval, and a history of all applied configurations.
Use the CoreWeave Intelligent CLI (cwic) to upgrade Node Pools to pending configurations or roll back to previous configurations. See the Node configuration visibility and management release notes for more information.
