Kradle API Server overview

The primary HTTP API server for Kradle, serving both the Kubernetes aggregated API (for data-plane resources like repositories, pull requests, issues, pipelines) and a REST convenience layer for the web UI. Listens on port 3080 by default. Handles authentication via Kubernetes service accounts and bearer tokens, org-scoped authorization, webhook dispatch, and SSE streaming for real-time updates. The aggregated API registers with kube-apiserver so that kubectl and client-go can interact with Kradle resources natively.
