Description: Node affinity is a set of rules used by Kubernetes to determine on which nodes a pod can be scheduled based on labels. These rules allow cluster administrators to define preferences for pod placement, which can be crucial for optimizing performance, availability, and resource management. Node affinity is divided into two types: hard affinity and soft affinity. Hard affinity requires a pod to run only on nodes that meet specified conditions, while soft affinity suggests preferred nodes but allows some flexibility in scheduling. This functionality is especially useful in environments where certain services need to run on specific nodes, such as applications that require access to particular hardware or must meet regulatory compliance requirements. Additionally, node affinity helps improve system resilience by allowing pods to be more efficiently distributed across available nodes, preventing overload on a single node and ensuring optimal resource utilization.
