Macos 在osx上尝试达到172.17.0.4:8080时出现minikube错误

我正在用osx上的minikube在本地做kubernetes教程。在步骤3中，我得到了错误

% curl http://localhost:8001/api/v1/namespaces/default/pods/$POD_NAME/proxy/
Error: 'dial tcp 172.17.0.4:8080: getsockopt: connection refused'
Trying to reach: 'http://172.17.0.4:8080/'%

知道为什么这在本地不起作用吗？更简单的请求确实有效

% curl http://localhost:8001/version

  "minor": "10",
  "gitVersion": "v1.10.0",

那么run命令正在启动节点，但是pod崩溃了？为什么?

$ kubectl run kubernetes-bootcamp --image=gcr.io/google-samples/kubernetes-bootcamp:v1 --port=8080

我可以毫无问题地提取图像

是一种可以在本地轻松运行的工具

Minikube运行单节点Kubernetes 群集在笔记本电脑上的虚拟机中，供希望试用Kubernetes或日常使用它进行开发的用户使用

回到你的问题上来。您是否已检查是否提供了足够的资源来运行Minikube环境

您可以尝试运行minikube并强制分配更多内存：

minikube start --memory 4096

为了进一步分析，请提供有关此安装和安装专用资源的信息

您使用的虚拟机监控程序的类型。

听起来像是网络问题。您的虚拟机无法从gcr中提取映像。io:443

以下是您的

kubectl所描述的kubernetes训练营xxx的吊舱外观：

从主机上尝试此操作，以缩小虚拟机或主机的网络问题：

吊舱真的在运行吗？
kubectl日志$POD\u NAME
有什么有趣的地方吗？这个错误消息听起来像是pod没有启动或者配置错误；pod中的进程需要监听0.0.0.0:8080。是的，教程还要求您运行
kubectl get pods
，并且pod正在您的输出中运行，pod未运行：>kubernetes-bootcamp-74f58d6b87-ntn5r 0/1您可以使用命令
kubectl cluster info
获取有关群集的所有信息，并检查代理是否存在。您可以使用命令
curlhttp://localhost:8001/api/v1/namespaces/default/pods/kubernetes-bootcamp-79c8445fcb-72cfd/
通过API获取pod信息。如何收集有关我的环境的信息？您是否在osx上并遵循本教程？接下来，我确定pod的ip地址为172.17.0.4:8080在安装minikube时使用了什么虚拟机监控程序以及Mac上有多少RAM？不确定虚拟机监控程序是什么，virtualbox？我在一台16gb内存和chrome的mac电脑上，打开了几个选项卡。我可以建议你：？
