How to hide files in a repository, leaving them for deployment?

Question

git

There is a repository with a project, several people are working on it.
I'm a maintainer, the others help.
The repository has secret keys and other files that I would not want to show anyone.
I can’t add them to gitignore, because these files are needed to auto-deploy the application.
How to proceed?

Answer 1

The repository SHOULD NOT contain such files.
These files should be added at the deployment stage, for example. Or be already on the server and be loaded, for example, through environment variables.
But not in the repository
