Google App Engine上的Node App无法访问Redis Sentinel
[英]Node app at Google app engine can't access Redis sentinel
问题描述
I m trying to use redis as data storage for performance. 
我正在尝试使用Redis作为性能的数据存储。
- app engine includes node app (using 'sentinel-redis' lib) -应用引擎包括节点应用（使用'sentinel-redis'lib）
- compute engines include redis-server & redis-sentinel (provided by GCP deploy management) -计算引擎包括redis-server和redis-sentinel（由GCP部署管理提供）
- the strange thing is that : node app works normally without error on compute engine (not in app engine) -奇怪的是：节点应用程序在计算引擎上正常运行，而没有错误（不在应用程序引擎中）
- i guess need something firewall rules that allows app engine to access to subnet that includes redis instances.. - 我猜想需要一些防火墙规则，允许应用程序引擎访问包含Redis实例的子网。
- here is deploy fail log: 这是部署失败日志：
ERROR: (gcloud.app.deploy) Error Response: [9] Application startup error: 错误：（gcloud.app.deploy）错误响应：[9]应用程序启动错误：
... events.js:160 throw er; ... events.js：160 throw er; // Unhandled 'error' event ^ //未处理的“错误”事件^
