问题：
kubernetes上的spring云数据流服务器在仪表板加载时出错
刘嘉木
正在尝试在kubernetes上运行Spring云数据流服务器。当我尝试打开仪表板url时(https://scdfserverurl/dashboard/#/apps）在浏览器中部分加载，并在日志中显示以下错误。其他组件skipper运行正常，可以访问url。

这是由于https-http重定向导致的，数据流服务器无法到达skipper/deployer restendpoint。下面的链接有详细信息链接
类似资料：
-
在spring cloud dataflow中，根据我的理解，每个流都是一个微服务，但数据流服务器不是。我说的对吗？
-
我通过Kubespray成功部署了Kubernetes，一切似乎都很好。我可以通过kubectl访问集群，列出节点、POD、服务、秘密等。还可以应用新的资源，仪表板endpoint可以让我进入仪表板登录页面。 我使用不同服务帐户的令牌登录（默认、kubernetes仪表板、kubernetes admin等）。。。每次登录时，我都会看到与kubespray dashboard中描述的相同的弹出窗口
-
我有一个Kubernetes集群，各种资源运行良好。我试图让仪表板工作，但在启动仪表板并输入服务帐户令牌时出现以下错误。 persistentvolumeclaims被禁止：用户“system:serviceaccount:kube system:kubernetes dashboard”无法在命名空间“default”中的API组“”中列出资源“persistentvolumeclaims” 它
-
加载仪表板 如何打开一个保存的仪表板： 点击侧边导航栏中的 Dashboard 。 选中一个仪表板并点击 Open 。如果您有很多仪表板，您可以敲入 Filter 字符串来过滤仪表板列表。 要导入、导出和删除仪表板，请点击 Manage Dashboards 链接打开 Management/Kibana/Saved Objects/Dashboards 。
-
我已经部署了SpringCloudDataFlow（SCDF）版本2.4。Kubernetes v1上的0。17.4使用minikube v1。8.2基于此参考。文档| Spring云数据流 我想在SCDF上启用基本身份验证。17.2基本认证但是我找不到Kubernetes或Spring更改SCDF pod安全性的相关文档。 我应该使用data flow config server shell更改
-
我正在尝试使用skipper服务器管理spring云数据流。 我按照这里的指示： https://docs.spring.io/spring-cloud-dataflow/docs/current/reference/htmlsingle/#getting-started-deploying-spring-cloud-dataflow 应用程序注册和流定义/部署进行得非常顺利，但是在我取消部署部署
