Adding a custom processor. To add a processor to NiFi you simply need to copy the `.nar` file into the correct location inside the container and run it. Processors in NiFi live in `/opt/nifi/nifi-1.6.0/lib/` so you can use the docker `COPY` command to copy your processor in.
Translating that to Nifi parlance, the simple flow will have just three parts: a GetFile processor, a PutFile processor and a connector to connect the two processors. Following steps detailed here, let us start the Nifi and navigate to http://localhost:8080/nifi/. The Nifi GUI is shown below: Note: this artifact is located at Hortonworks repository (https://repo.hortonworks.com/content/repositories/releases/)

NiFi can do what you need and scale as needed. Downside of NiFi, it is harder to thoroughly test than traditional code for complex designs and several hundred plus processors. I would use it to connect small data flows between systems but avoid it for large implementations. Not that NiFi can't do it but NiFi can become monolithic fast.
