 ## Cluster-scoped RBAC
 
-If you'd like to set up the k8sattributesprocessor to receive telemetry from across namespaces, it will need `get`, `watch` and `list` permissions on both `pods` and `namespaces` resources, for all namespaces and pods included in the configured filters. Additionally, when using `k8s.deployment.uid` or `k8s.deployment.name` the processor also needs `get`, `watch` and `list` permissions for `replicasets` resources. When extracting metadatas from `node`, the processor needs `get`, `watch` and `list` permissions for `nodes` resources.

When using `k8s.node.uid` or extracting metadata from `node`, the processor needs `get`, `watch` and `list` permissions for `nodes` resources.
 
 Here is an example of a `ClusterRole` to give a `ServiceAccount` the necessary permissions for all pods, nodes, and namespaces in the cluster (replace `<OTEL_COL_NAMESPACE>` with a namespace where collector is deployed):
