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!

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.

I don't at the moment, because I don't have a need for it, but I did for a while run a PoC with Step CA, and that seems like the easiest way to get up and running, even if its features are overkill for a home lab.

Step CA is really nice if you want to learn more about how a real CA works. Had some fun playing with it but yeah it's a bit overkill for home lab xD.

You can achieve the same result with openssl with less complexity !

Thanks, I have been recommended Step-CA a few times under this post, I'll take a look!
