SharedIndexInformer watches only pods of its own namespace when run in the cluster

[adferrand]

I am trying to build a Kubernetes controller using fabric8io/kubernetes-client. As of now I use the version 4.10.3.

For that purpose I am constructing a SharedIndexInformer to properly watch resources events emitted by the cluster. I will take pods as resources example here.

So the SharedIndexInformer is constructed following this piece of code:

SharedIndexInformer<Pod> sharedIndexInformer = kubernetesClient.informers().sharedIndexInformerFor(
                objectClass,
                objectClassList,
                10 * 60 * 1000);

Following, lot of code to attach events handler, start the indexer, have a reconciliation loop and so on.

The indexer is working perfectly fine when started from my local machine, and I see all pods being listed. However, when I run it on a pod in my cluster (with RBAC properly defined), I see only the pods for the namespace where the pod is run on.

I checked explicitly in the pod that, using kubectl, the associated service account was capable to list all pods in the cluster, and not only in the current namespace.

What am I missing?

Thanks in advance for your help!
