CoreDNS monitoring with stunnel

This article can be seen as a follow up to Monitor with SSH and Prometheus, but in a different, hopefully, more simple way.¹

Now I want to monitor CoreDNS running as a DNS to HTTPS proxy in my home network.

In one word: stunnel. (I had to upgrade Raspbian to Debian Testing to get an up to date stunnel though.)

I’ve setup a simple TLS tunnel with a pre-shared-key between my prometheus server and the NATted Raspberry Pi running in my homenetwork.
