Kicking the tires of Prometheus using Docker on Fedora

Straight from the Prometheus documentation: "Prometheus is an open-source systems monitoring and alerting toolkit originally built at SoundCloud."

I haven't had a chance to even take a look at using Prometheus.  Here I'll go over the steps I had to follow to get a working local Prometheus install monitoring my local Docker daemon so I could see metrics through the Prometheus dashboard.

First things first, here are the versions of what I am using (eh, until we find out what the problem is (listed below)):
  • Fedora 25
  • Docker
    • docker-1.12.6-6.gitae7d637.fc25.x86_64
    • docker-common-1.12.6-6.gitae7d637.fc25.x86_64
    • docker-latest-1.12.6-2.git51ef5a8.fc25.x86_64
    • Prometheus
      • prom/prometheus b0195cb1a666
    So, there were a couple of places I went for documentation to get started:



    So, following those docs, I tried to use the default Fedora Docker configuration.  That did not work.  The Docker documentation was off, at least for the version of Docker I am using.  By default, in Fedora, you get a Docker package that is a bit out of date.  Here are the steps I took and what I had to do as a workaround.
