Can't find the Gateway entry point

[ivanrusanov]

Hello!

When I am trying to run docker file ibheadless I get the following error:

20:41:54:708 IBController: using default settings provider: ini file is /etc/ibcontroller/conf.ini
20:41:54:708 IBController: using default login manager: getting username and password from args but not found. Will get from settings

Do I need to install something before running (e.g. ib-controller)?
