Prow and Quickstart

Prow is a Kubernetes based CI/CD system. Jobs can be triggered by various types of events and report their status to many different services. In addition to job execution, Prow provides GitHub automation in the form of policy enforcement, chat-ops via /foo style commands, and automatic PR merging.

NOTE|WARNING: In order to make Prow work fine with your repo, the Kubernetes cluster MUST be reachable by GitHub Webhook.
