02-gateway

What problem does it solve?

This Skill helps you understand how edgion-gateway (the data plane) turns Controller-delivered configuration into lock-free runtime proxy behavior, across startup, request handling, routing, TLS, plugins, load balancing, backends, observability, and LinkSys integrations.

Core Features & Use Cases

• Pingora data-plane lifecycle: map the 8-phase ProxyHttp flow and TCP ConnectionFilter behavior to concrete runtime responsibilities and hot-path constraints.
• Config sync and atomic runtime updates: follow the gRPC Watch/List pipeline and ArcSwap-based store design that enables instant hot reload without blocking request handling.
• Routing, TLS, plugins, and traffic management: connect route engines (HTTP/gRPC/Radix+Regex, TCP/TLS/UDP tables), TLS match/callback logic, plugin execution phases, and backend selection strategies into a single mental model.
• Observability and external systems: trace zero-copy AccessLog generation, Prometheus metrics, protocol logs, and LinkSys providers (ES/Redis/Etcd/Webhook/LocalFile).

Quick Start

Use the 02-gateway skill to build a complete edgion-gateway runtime map for debugging a hot-reload routing issue affecting a specific protocol (HTTP/gRPC/TCP/TLS/UDP).
