Policy Reporter

Motivation

Kyverno ships with two types of validation. You can either enforce a rule or audit it. If you don't want to block developers or if you want to try out a new rule, you can use the audit functionality. The audit configuration creates PolicyReports which you can access with kubectl. Because I can't find a simple solution to get a general overview of this PolicyReports and PolicyReportResults, I created this tool to send information about PolicyReports to different targets like Grafana Loki, Elasticsearch or Slack.

Policy Reporter provides also a Prometheus Metrics API as well as an standalone mode along with the Policy Reporter UI.

This project is in an early stage. Please let me know if anything did not work as expected or if you want to send your audits to unsupported targets.
