为什么AWS提供程序的OpenShift安装程序无法连接到Kubernetes API？

Question

OpenShift AWS安装程序无法等待Kubernetes API出现，并出现致命错误“等待Kubernetes API：超出上下文期限”：

就我而言，安装程序尝试连接到链接到不存在的端点的Kubernetes API。一种迹象表明，如果在运行诸如oc之类的简单命令时oc whoami-客户端挂起，则它实际上试图连接到同一端点（假设已设置KUBECONFIG）。原来，这与Route 53托管区域有关，尤其是与子域有关。当针对子域安装OpenShift时（例如我的情况），需要在主域中创建引用该子域的记录集。因此，对于openshift.example.com，请在aws控制台中执行以下操作：转到路线53->托管区域->单击openshift.example.com。 （如果不存在，请创建一个托管区域）->复制NS记录，例如：
