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

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 do have Vault PKI set up but I don’t use it that much. It’s only if I want to do mTLS with something.

    For almost all of my actual services, I use a wildcard cert that covers something like *.int.example.com. I use acme.sh to create and renew the cert then have a python script that copies it to any vms or services that need it
