+# deployment.yaml — AIOps 应用 (embed 前端嵌入后端, 单容器单端口)
+# ----------------------------------------------------------------------------
+# - 镜像 aiops:embed（前端通过 go:embed 内嵌进同一二进制）
+# - 单端口 8080 = API + WebSocket + 前端 SPA 静态资源
+# - 配置优先级: 环境变量 > config.yaml > 默认值 (viper AutomaticEnv)
+# - 环境变量命名: 配置键 database.host → DATABASE_HOST (全大写, 点变下划线)
+# - Service: NodePort 30080 → 8080
+#
+# 部署: kubectl apply -f deployment.yaml
