Need help deploying one app module

[ipreencekmr]

I have created a root module and it's child and I am able to run locally and through module map url. However I am unable to find any documentation for production deployment process. What exactly to be deployed and how to run at production environment.

While configuring production, I am facing following issue

Error: Both the root-module-name argument and the ONE_CLIENT_ROOT_MODULE_NAME environment variable have been provided, but only one may be set at once.
