+# ingress.yaml — Ingress 入口路由 (nginx-ingress)
+# ----------------------------------------------------------------------------
+# 路由规则 (embed 模式: 所有流量 → aiops:8080):
+#   /api/*  -> aiops:8080  (后端 API)
+#   /ws/*   -> aiops:8080  (WebSocket 长连接)
+#   /       -> aiops:8080  (go:embed 前端 SPA)
+#
+# 前提: 集群已安装 nginx Ingress Controller。
+# 部署前请修改 host (aiops.local) 与 ingressClassName 为实际值。
+# 部署: kubectl apply -f ingress.yaml
