- Implement node affinity to prevent scheduling on vkvm-us2 - Update affinity section in daemonset.yaml - Ensure that the DaemonSet runs only on specific nodes This change introduces a node affinity rule to the DaemonSet configuration, allowing it to avoid scheduling on nodes labeled with `kubernetes.io/hostname` set to `vkvm-us2`. This helps to ensure resource allocation and performance by restricting the DaemonSet to the desired nodes.
