What should I have on my "portfolio"?

I’d like to be a network administrator but I’m sort of at a loss as to how I can actually show proof of the projects I’ve worked on.

I have my CCST and CompTIA A+ but I don’t believe that these two certifications and some college are enough to land an internship.

I also have a self hosted website that chronicles each of my projects in greater detail. Visitors can click on subheadings and see the scripts I’ve created (netmiko automation, bash cron jobs) as well as my explanation of common routing protocols implemented with GNS3.

I’m not interested in programming. Are network engineers posting their projects on github? I’m not even sure if I would be asking this question a decade ago but with everyone entering Computer Science it seems to me that I should have a github link on my resume. Maybe I should sit down and learn network programming with C/Python etc but I wouldn’t be working extensively with code as a network administrator anyways so I’m a little confused.
