How to change the domain name for a google cloud bitnami installation

[Michael Fackerell]

Hi I got Open edX installed using bitnami on the google cloud. I need to know where to find out how to configure the server. The first thing I'd like to do is use a domain name instead of an IP address http://104.154.171.82/ I'd like to use ozetutors.com. I've already pointed the DNS A records to the IP but it isn't enough - you can't log in and I think the installation or server needs to know about the domain name.

Where can I find out how to customise my installation of Open edX?

Thanks for any help.
