Manage Kubernetes Node Fleets with NodeWright | NVIDIA Technical Blog

This post introduces NodeWright, an open-source, Kubernetes-native package manager for declaratively configuring and safely updating host operating systems across GPU clusters. It orchestrates a six-stage sequence (cordon, wait, drain, apply, interrupt, uncordon) to manage host-level changes like kernel parameter tuning and CVE remediation without disrupting workloads, respecting PodDisruptionBudgets and non-interruptible workload labels. NodeWright's DeploymentPolicy resource enables progressive rollouts with configurable strategies and thresholds. It integrates with NVIDIA AI Cluster Runtime and DSX OS, providing a controlled path from provisioned to schedulable nodes.
