How Workbench containers need to be accessible through public IP?


I have done the RubyKube’s workbench setup in AWS server(Ubunut 16.04) and it’s running successfully. Now, I can able to access like auth.wb.local, api.wb.local…etc by adding those url in /etc/host. But I couldn’t accessible through server ip. Can you please someone help me how to access through IP instead of using auth.wb.local?
