Do you run a private CA? Could you tell me about your certificate setup if you do? - Lemmy.World

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!
