Stop the caddy message and start our own init notifications. Log the version of CoreDNS when starting up. Fix all middleware's setup functions so that return the error prefixed with *which* middleware was failing; leads to better debuggable errors when starting up.
health
This module enables a simple health check.
By default it will listen on port 8080.
Restarting CoreDNS will stop the health checking. This is a bug. Also this upstream Caddy bug.
Syntax
health
Optionally takes an address; the default is :8080. The health path is fixed to /health. It
will just return "OK" when CoreDNS is healthy.
This middleware only needs to be enabled once.
Examples
health localhost:8091
