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 run a crude automation on top of OpenSSL CA. It checks for certain labels attached to kubernetes services. Based on that it creates kubernetes secrets containing the generated certificates.

      I would be very interested in your setup. Could you give me a high-level overview of how your setup works?

      I’d also like a link to your automation/configuration if you would. Thanks!
