I have a well-documented obsession with pretty URLs, and this extends even to my internal home network. I have way too much stuff bouncing around in my head to have to remember IP addresses when a domain name is much easier to remember. LetsEncrypt launched to offer free SSL certificates to anyone, but the most crucial feature of their infrastructure, and one someone should have figured out before then, was scriptable automatically renewing certificates. Basically they validate you do in fact own the domain using automated methods, then issue you the new certificate. Thus, your certificates can be renewed on a schedule with no interaction from you. Traditionally, they have done this by placing a file in the webroot and looking for that file before issuing the certificate (see my earlier blog post about Zero Downtime nginx Letsencrypt Certificate Renewals Without the nginx Plugin for more detail about this.) But what happens when you want to issue an internal certificate? One for a service that is not accessible to the outside world, and thus, not visible using the webroot method? Well, it turns out there is a solution for that too!
