为什么 AWS 提供商的 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 可用并出现致命错误 "waiting for Kubernetes API: context deadline exceeded":

$ openshift-install create cluster --dir=$HOME/openshift --log-level debug
...

Answer 1

在我的例子中，安装程序试图连接到 Kubernetes API 链接到一个不存在的端点。一个迹象表明如果 oc-client 在运行一个像 oc whoami 这样的简单命令时挂起 - 它实际上尝试连接到同一个端点（假设 KUBECONFIG 已设置）。
事实证明，它与 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（如我的情况），需要在主域中创建引用子域的记录集。因此，对于 openshift.example.com，请在 aws 控制台中执行以下操作：
转到 Route 53 -> Hosted zones -> 单击 openshift.example.com。（如果不存在 - 创建一个托管区域）-> 复制 NS 记录，例如：

ns-711.awsdns-24.net.   
ns-126.awsdns-15.com.   
ns-1274.awsdns-31.org.   
ns-1556.awsdns-02.co.uk.

返回托管区域 -> example.com。 -> 创建记录集：
为 openshift.example.com 创建记录集，类型：NS - 名称服务器，值：粘贴复制的 NS 记录。

此更改后安装成功。
