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.

Thanks, I recognise the challenge in getting this working rather that simple relying on Let's Encrypt. A little bit of money is not the problem here though; I have made a personal choice to use a private, reserved domain for my internal network and simply do not want to use a public domain for it.

You don't have to make the public domain, well, public. You can not hook up any DNS records for it, so externally it won't resolve anywhere and just use internal DNS.

Of course. I just want to take the learning experience from it as well has using a reserved domain instead of a public domain I'd purchase
