How to add a file to gitignore but keep it in the repository?

Question

git

Hello
Is it possible to add a file to gitignore but keep it in the repository?
let's say there is a settings file (for connecting to the database) and it should be, but each has its own settings for connecting.
Thanks

Answer 1

Everyone can store their settings for connecting to the database in a specific file. Add this file to gitignore and it will remain only on the local machine - for each developer.
The whole point of gitignore is to not include the specified files in the repository.

Answer 2

Off topic answer but good 12factor.net/config

Answer 3

In this case, it would be reasonable to use a file like db.config.example
