+_Optional, Default: false_

+When this parameter is set to `true`,
+Traefik will not discover cluster scope resources (`IngressClass` and `Nodes`).
+By doing so, it alleviates the requirement of giving Traefik the rights to look up for cluster resources.
+Furthermore, Traefik will not handle Ingresses with IngressClass references, therefore such Ingresses will be ignored (please note that annotations are not affected by this option).
+This will also prevent from using the `NodePortLB` options on services.
