Golang HTTP server with Prometheus instrumentation

This image can be used to serve static content over HTTP, while exporting metrics in Prometheus format.

HTTP requests are instrumented with metrics to count the total amount of time spent serving HTTP requests, as well as the number of requests received. These metrics are all exposed on a separate "metrics" port for collection, in Prometheus format.

This image will serve static content from the /www directory on port 5000 by default. Prometheus metrics are exposed on port 8080 by default.
