Question

我在这里关注Kubernetes指南：https://kubernetes.io/docs/tasks/configure-pod-container/assign-cpu-ram-container/

当我运行此命令时：

kubectl create -f http://k8s.io/docs/tasks/configure-pod-container/cpu-ram.yaml

大约30秒后，我收到此消息：

Unable to connect to the server: dial tcp 172.17.0.1:4321: i/o timeout

我在网上尝试过很多建议（包括Stack Overflow），但无法弄明白。我在Google云端平台上使用Google Cloud Shell并尝试设置Kubernetes（通过其网站上的官方Kubernetes指南）。以下是gcloud info的输出：

您正在尝试在不存在的群集中安排Pod。在创建资源之前，您需要配置基础集群。

我建议您阅读https://k8s.io的文档，以了解Kubernetes及其构建模块。该文档也是了解如何配置Kubernetes集群的好地方。在Google Cloud上，这非常简单。
