port-scan-exporter

This is a simple prometheus exporter that periodically scan pods in the cluster (not using HostNetwork) for open TCP ports.
The scans happen concurrently, using a configurable number of goroutine per each pod.

Installing

A helm chart is provided in the chart directory.
Simply run

helm package

in the chart directory to generate the package. You can then install the chart as usual, e.g.:

helm upgrade --install port-scan-exporter chart/port-scan-exporter-0.1.0.tgz --values my_custom_values.yaml

Refer to the values.yaml file in the chart subdirectory for the default values.
