Rails - Figaro gem - how can I add a collaborator to my repo without sharing application.yml variables

I am using rails 5 with figaro gem to manage my environment variables.

I have just started working with a coding coach, who is setting up my repo on his system.

Is there a way for me to share my repo (so that he can configure it) without giving him the codes in my application.yml?

Add application.yml to git ignore. If the file is already commited in git history, you can follow instruction in here to let git 'forget' it completely.
