Question

我今天正在使用我的Openshift应用程序而且没有更改与mongodb连接相关的任何内容我开始收到此消息：

/opt/app-root/src/node_modules/mongodb/lib/server.js:242
        process.nextTick(function() { throw err; })
                                      ^

有一点不同之处在于我看到由于某种原因mongodb服务尝试了新部署失败，所以我手动运行了一个。

我还注意到IP地址尝试连接的是mongodb的群集IP，但当前运行的pod的节点IP不同。

有人可以帮我弄清楚是什么触发了连接中断？

谢谢

在给定的Project范围内，针对＆＃34; mongodb＆＃34;的主机名的请求应该被路由到名为＆＃34; mongodb＆＃34;的Kubernetes Service。（如果有的话）。

调试此连接问题：

尝试使用OpenShift Web控制台在前端容器中打开实时终端。前端容器必须与数据库服务
键入env以列出前端可用的环境变量。如果在创建＆＃34; mongodb＆＃34;之后启动此容器。服务，配置字符串应该是可见的环境
从实时终端运行curl $MONGODB_SERVICE_HOST:$MONGODB_SERVICE_PORT以验证mongodb服务
