Fluentd Configuration

I have installed fluentd daemonset using https://github.com/fluent/fluentd-kubernetes-daemonset/blob/master/fluentd-daemonset-azureblob.yaml

I want to fetch logs of a particular (Not all namespaces) Namespace in K8s. Can someone help me with the configmap how to fetch logs of a particluar namespace and send them to azureblob container
