The exclude-list allows to filter specific resource accounting from NRT's objects per node basis. The CRs created by the topology-updater are used by the scheduler-plugin as a source of truth for making scheduling decisions. As such, this feature allows to hide specific information from the scheduler, which in turn will affect the scheduling decision. A common use case is when user would like to perform scheduling decisions which are based on a specific resource. In that case, we can exclude all the other resources which we don't want the scheduler to exemine. The exclude-list is provided to the topology-updater via a ConfigMap. Resource type's names specified in the list should match the names as shown here: https://pkg.go.dev/k8s.io/api/core/v1#ResourceName This is a resurrection of an old work started here: https://github.com/kubernetes-sigs/node-feature-discovery/pull/545 Signed-off-by: Talor Itzhak <titzhak@redhat.com>
