@ -84,3 +84,10 @@ If you have RBAC authorization enabled (as is the default e.g. with clusters
initialized with kubeadm) you need to configure the appropriate ClusterRoles,
ClusterRoleBindings and a ServiceAccount for NFD to create node
labels. The provided template will configure these for you.
## Informer List Pagination
When NFD Master starts up it starts an informer on the nodefeatures resources.
These resources can be large and in a large cluster this initial list call to sync the informer cache can be
expensive and heavy on api-server/etcd. You can use the `informer-list-size` argument to NFD master to control pagination size
to help control the load during NFD-Master restart.
