Hi, I was looking at private CAs since I don’t want to pay for a domain to use in my homelab.

What is everyone using for their private CA? I’ve been looking at plain OpenSSL with some automation scripts but would like more ideas. Also, if you have multiple reverse-proxy instances, how do you distribute domain-specific signed certificates to them? I’m not planning to use a wildcard, and would like to rotate certificates often.

Thanks!

Edit: thank you for everyone who commented! I would like to say that I recognise the technical difficulty in getting such a setup working compared to a simple certbot setup to Let’s Encrypt, but it’s a personal choice that I have made.

    never expose such certificates on the wild wild west ! Keep those certificate in a closed homelab you access through a secure tunnel on your LAN !

    I’m curious, what’s the reason?

      In many architectures in which certificates are used, a client with a valid certificate is a trusted client, so a certificate falling into the wrong hands is problematic.
