# ingress.yaml — Ingress 入口路由 (nginx-ingress)
# ----------------------------------------------------------------------------
# 路由规则:
#   /api/*  -> aiops-backend:8080  (后端 API)
#   /ws/*   -> aiops-backend:8080  (WebSocket 长连接)
#   /       -> aiops-backend:80    (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
