Public Hi Endre,
I certainly agree with the bare metal option. The reason I have a specific request for OpenShift is the requirement to adhere to organisational architectural road map. I cannot agree more that it is not a single person task. I was working on it for few days with OpenShift administrator (on CC list) helping me out. Your links certainly give an impression that this task is not for faint hearted.

This is definitely not a few days task for a single person. Why not run NiFi just in docker (docker-compose)? Or on bare metal?
