Is this back to not understanding basics? The config does not exist. Best I can tell that file is created when you run the init command. For the second server you do not need to run that, per the instructions. (unless it was missed). I see when creating hte master node the file existed and it was copied. But so far for the worker node I do no see how it is created.
