Kueue: Kubernetes-Native AI Workload Scheduling with CoreWeave

This post introduces Kueue as a Kubernetes-native system for AI training workloads on Coreweave Kubernetes Service (CKS). It explains the challenges of traditional Kubernetes for GPU-intensive AI jobs (inelastic GPU nodes, 'all-or-nothing' requirements) and how Kueue addresses these with 'all or nothing' scheduling, ResourceFlavors for fine-grained resource management, and ClusterQueues/LocalQueues for multi-tenant resource sharing, including quota borrowing and preemption. Coreweave provides a Helm chart for Kueue installation and integrates its metrics into Grafana.
