Cloudera Flow Management - Kubernetes Operator - how to add custom processor NAR?

karsten — Tue, 21 Apr 2026 06:11:39 GMT

Hi,

We have deployed Cloudera Flow Management through the Kubernetes Operator on a k8s cluster. What's the best practice how to add custom processor NARs in this environment?

On a plain (not containerized) NiFi deployment I would put the NAR into the extensions sub folder of the NiFi deployment and it gets unpacked during startup of NiFi.

How does it work with the Cloudera Kubernetes Operator version of NiFi? We have a NFS share available that could be mapped to a container's sub folder.

Has anyone done this successfully?

Thanks,
-karsten

Hello @karsten,

I think this is what you are looking for:
https://docs.cloudera.com/cfm-operator/2.11.0/configure-nifi-cr/topics/cfm-op-configure-nifi-cricustom-nar-providers.html

There you can see the steps on how to configure a custom NAR for CDF on Kubernetes Operator.

Let me know if that helps.
