So I designed my MiniFi flow in the Apache NiFi UI (pretty soon there will be a special designer for this). You then highlight everything there and hit ‘Create Template.’ You can then export it and convert it to
config.yml. Again, this process will be automated and connected with the NiFi Registry very shortly to reduce the amount of clicking.
This is an example. When you connect to it in your flow you design it in Apache NiFi UI, you will connect to this port on the Remote Processor Group. If you are manually editing one (okay never do this, but sometimes I have to), you can copy that ID from this Port Details and past it in the file.
I like this as an overview of NiFi’s capabilities and a sneak peek at where they’re going.
