Let's Encrypt won't work without an Apache or other server installed and running, but I have a specific use machine that doesn't have or want a http server of any kind, but I would like to give it a let's encrypt cert. for port 10000 access.
I can of course setup a apache server, then tear it down every 3 months, but I was really hoping for a more elegant approach.
A single use miniserv? Fire it off on 80, get the cert, then close it down? Use the system name (which is a valid name) to make the request.
Just throwing out ideas...
