I’m not even sure this title makes sense. I’m looking to handle LE certificates in cloudflare automatically. Specifically multi level subdomains.
You can hand off subdomain certs to them for single level, but the moment you want multi level you need to manage the certs yourself.
What I’m hoping for is an open source/self hosted tool that is meant to handle certificate requests and distribution. I just don’t know if such a tool even exists, and searching around hasn’t yielded results.
Does anyone have any thoughts?
Would cert-manager for Kubernetes be approximately what you’re looking for? In that particular case, it’s a service that runs in a K8s cluster, that can auto-request CSRs and send them to Lets Encrypt using one of the challenge types. It takes care of managing the returned certificates, such as renewing them before expiration and registering the private keys within the K8s key store.
I presume that you’re not already using K8s, so maybe that project will help you find the keywords to describe the sort of certificate manager that you want.
I’m not currently using kubernetes but its something I’ve thought of looking into before. I’ll definitely give that a look for better terminology though!
