我使用节点创建了REST,并使用Kubernetes和Docker对其进行了封装。kubernetes吊舱是在一个小型环境中运行的,用于开发目的。
应用程序运行良好,现在它给出了下面的错误。
[distribution] Initial Distribution API Database connection error occured - MongooseServerSelectionError: Could not connect to any servers in your MongoDB Atlas cluster. One common reason is that you're trying to access the database from an IP that isn't whitelisted. Make sure your current IP address is on your Atlas cluster's IP whitelist: https://docs.atlas.mongodb.com/security-whitelist/

[distribution] }这个问题看起来像是一个MongoDB连接URL/访问问题,但是连接字符串是正确的。(在MongoDB云支持下进行了双重检查)。每个人都有相关的网络访问。

我还可以确认可以使用相同的连接URL通过MongoCloudDB指南针访问MongoDB。

我的猜测是,MongoDB数据库无法从迷你库内部的吊舱建立连接。
你们中有谁知道如何克服这个问题吗?

下面的台阶对我有用。来自另一个Github用户的帮助。
I have stopped and deleted the existing minikube
Downloaded "https://github.com/kubernetes/minikube/releases/download/v1.8.2/minikube-windows-amd64.exe" and renamed it to minikube.exe
Placed the above exe in the same folder in which my kubectl.exe is existing. (C:\kube). This path is added to the environment variable "Path" of my user.
Created a hyperv switch, Open Hyper-V Manager, Click on Virtual Switch Manager, Create New Virtual Network Switch, Select external type, and OK.
Ran this command `minikube start driver="hyperv" --hyperv-virtual-switch="MY-SWITCH"`
minikube successfully started然后,我创建了一个部署,它成功地提取了映像并运行容器,没有任何问题。

在您的配置中,mongdb不能从集群内部解析,您必须创建一个外部服务来使uri可解析。请参阅下面的配置作为示例。
