Prometheus demo in a test-kitchen box
node-exporter doesn't work with the Docker cookbook for unknown reasons. I didn't delve further into it. Simple workaround for the purposes of this demo is to converge the box, and then login and run the commented Docker command to bring the node-exporter online.
With this test-kitchen box, you can find:
Prometheus at port 9090
Alertmanager at port 9093
Grafana at port 3000
Mysqld Exporter at port 9104
Node Exporter at port 9100
