Private repository for templates

[LTM]

I did a quick search and couldn't find anything useful on the subject.

 

Is there a way that I can use a private GitHub or GitLab repository to add application templates? The reason I am asking is because I want to use it as a backup in case is something goes wrong and I need to start from fresh. I don't want to create a public repository because some of my containers contain passwords that would be made visible to the public. I know I can save the XML and copy them over which is what I am doing now, but would like to be able to get them back over quickly if the need arises.

 

I was thinking that there would be a way to add a public/private SSH key and going that route but I can not seem to find an updated guide on how to do that since it looks like 6.8 made all of the previous methods obsolete but I an still going down that rabbit hole.

 

Thanks!
