Citizen Node(Endpoint node) configuration

Hello, guys. Is there any guide of running a Citizen Node(Endpoint node)? Ive tried using docker image provided by 'iconloop', but it doesnt seem to be clear. The server doesn`t even receive any requests while in logs I get “Exception in worker process
Traceback” Error. Maybe there are some prerequirements for running this node? Or what could possibly the issue? Thank you!
