Set up Devilbox on a VPS

In the tutorials, I see how to set up Devilbox on a local server, using localhost ( I’m not clear on how to do this on a cloud virtual private server, and be able to access the site over the web.

I’m running CentOS 7 with a static ip. I loaded GIT, Docker, Docker-Compose, and DevilBox all okay. I can’t just go to “localhost” to see the DevilBox page. Where do I go? Can all the settings be configured in the env file? Or do I need to configure the external etc/host file? I’m just not sure of how this thing works.
