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.
Self-host your own ACME server. Then you can use certbot pointed there.
These instructions are old so not sure if newer/better ways, https://blog.sean-wright.com/self-host-acme-server/
Thank you, I was looking to host Step-CA, whilst OpenSSL is another option. I’m also planning to combine it with a vault for secrets like Conjur and encrypt the volumes underneath. I want to reach the best security posture possible in this kind of setup
