The NodeFeatureGroup is an NFD-specific custom resource that is designed for grouping nodes based on their features. NFD-Master watches for NodeFeatureGroup objects in the cluster and updates the status of the NodeFeatureGroup object with the list of nodes that match the feature group rules. The NodeFeatureGroup rules follow the same syntax as the NodeFeatureRule rules. Signed-off-by: Carlos Eduardo Arango Gutierrez <eduardoa@nvidia.com>
