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.
Why bother with certificate rotation in a homelab environment? You could issue certificates for three years and just call it a day.
Personally, I have experience with Microsoft Certificate Services, which works pretty well out of the box and is also quite well supported. But you need a Windows Server for it.
It’s just a personal feeling really, I feel better having them being rotated. Of course, when it comes to rotating client certificates, I might have to think long and hard about the pain I’m about to inflict on myself.
I’ll take a look at MCS, although I’d prefer not having to trust Microsoft on things critical to my lab
