Jul 23, 2025 · What is Node Affinity? Node Affinity in Kubernetes is a feature in Kubernetes that facilitates us to specify the rules for scheduling the pod based on the node labels. 5gb` slice needs the correct resource limit, a toleration for the GPU node taint, and a node affinity rule to ensure it lands on a MIG-enabled node. The predicates system consists of two phases: PreFilter: Validates pod requirements before checking individual nodes, potentially rejecting the pod early if no node can satisfy its requirements Filter: Validates whether a specific node can Mar 3, 2026 · Description: Learn multiple techniques for assigning pods to specific nodes on Talos Linux including nodeSelector, affinity rules, and nodeName. A StorageClass provides a way for administrators to describe the classes of storage they offer.
