Question

我在由kubernetes管理的google计算引擎上运行nodejs api作为pod。 API很好地连接到数据库，但它突然失败，显示此错误：

listening to http server on 0.0.0.0:8080...

events.js:160
      throw er; // Unhandled 'error' event
      ^
MongoError: failed to connect to server [mongo:27017] on first connect [MongoError: getaddrinfo ENOTFOUND mongo mongo:27017]

    at process._tickDomainCallback (internal/process/next_tick.js:128:9)

我尝试重启prods，删除并重新创建容器但没有成功？

这就是我连接数据库的方式：

mongoose.connect(process.env.MONGO_DEV_URL || process.env.MONGODB_URI || 'mongodb://mongo:27017:yaxiDb/yaxiDb', { useMongoClient: true });

如何调试此问题，可能出现问题？

我刚刚找到了解决方案，创建服务的顺序很重要。我删除了使用该数据库的所有服务并重新创建它们：

API Pod无法连接到同一个kubernetes集群中的mongo pod
