从Rancher服务器重新安装后无法访问Kubernetes仪表板

Question

第一次从Rancher服务器安装Kubernetes环境成功。

删除它并再次安装，所有堆栈都变为绿色，但是当访问Kubernetes仪表板时，只有一个空白页面。

检查仪表板的容器日志：

$ docker ps -a | grep dash

2017/11/27 10:16:21 Error while initializing connection to Kubernetes apiserver. This most likely means that the cluster is misconfigured (e.g., it has invalid apiserver certificates or service accounts configuration) or the --apiserver-host param points to a server that does not exist. Reason: the server has asked for the client to provide credentials

Answer 1

线索在您收到的信息中：

  

2017/11/27 10:16:21初始化与Kubernetes的连接时出错   API服务器。这很可能意味着群集配置错误   （例如，它具有无效的apiserver证书或服务帐户   配置）或--apiserver-host param指向服务器   不存在。 原因：服务器已请求客户端   提供凭据有关详细信息，请参阅故障排除指南   信息：   https://github.com/kubernetes/dashboard/blob/master/docs/user-guide/troubleshooting.md

服务器需要凭据，请阅读故障排除指南以了解如何更正它。
