Running NiFi 2.8 in stateless mode

[#1]

Previously we used NiFi 1.24, running it in OpenShift containers via the entrypoint "./bin/nifi.sh stateless...". Now I'm trying to migrate the dataflow to version 2.8.0 and am encountering an error - the "stateless" parameter for nifi.sh is now missing. I read all the documentation in the NIFI release notes and did not find information about this anywhere. Git still says that you can run it this way (nifi-stateless-assembly readme).
Tell me, is there any possibility to run the NiFi 2.8.0 distribution via the console in stateless mode? How to use a separate nifi-stateless distribution?

Hello @Dagonvlg, 

As far as I know, NiFi 2 does not have a stateless mode to the entire service. 
That was removed. 

But what it offers is an stateless engine. You can configure it at Processor Group level:

Hello @vafs, 
How to use nifi-stateless-2.8.0-bin.zip in this case? As I understand it, it contains everything that was removed from the main distribution nifi-2.8.0-bin.zip (i.e. stateless.properties)
Readme has not been updated for three years (https://github.com/apache/nifi/blob/rel/nifi-2.9.0/nifi-stateless/nifi-stateless-assembly/README.md#...), it still says that you can run it as a entire service

Hello @Dagonvlg, 

The best option should be on NiFi UI, in that way you can execute it as stateless:
