Kubernetes API pod拒绝连接

我目前正在尝试使用CoreOS和Kubernetes建立一个小型集群。首先，我将学习本教程。我有三台CoreOS机器在VirtualBox上运行，使用vagrant。我达到了教程的结尾，但被卡住了

我似乎能够使用

systemctl start kubelet

启动kubelet，但似乎无法连接到API服务器。似乎它没有启动API服务器，但尝试先连接到它

当我输入

curl时http://127.0.0.1:8080/version

，我得到

curl:（7）连接到127.0.0.1端口8080失败：连接被拒绝

返回

Journalctl只是告诉我kubelet正在尝试连接到API服务器，由于无法访问API服务器，我无法使用kubectl查看Pod的情况。我应该如何解决这个问题

编辑：

我手动执行了docker命令，并返回以下内容：

您将在下一步中设置apiserver。这是服务于127.0.0.1:8080的事物。一旦apiserver启动，kubelet应该停止抱怨。您提到的

curl

命令在这一点上也应该起作用。

我现在放弃了这个设置。我认为它与ssl设置中的错误配置有关。现在，我只是使用指南，结合前面提到的教程，从配置文件中删除了所有与ssl相关的内容。这给了我目前的工作设置。

嗨，谢谢你的回答。我在本教程的第3部分看到了“设置kube apiserver Pod”一节。奇怪的是，在第2部分中，他们要求您等待api服务器出现。我在下周一之前没有办法测试这个。我会告诉你它是否成功。我似乎错过了一些东西，因为第3部分没有谈到设置API服务器。问题仍然存在。它表示要

wgethttps://raw.githubusercontent.com/coreos/pods/master/kubernetes.yaml

和

sudo cp kubernetes.yaml/etc/kubernetes/manifests/

。

kubernetes.yaml

包含运行kube apiserver的说明，

cp

命令将文件放入一个目录中，kubelet将自动检测并读取文件并启动apiserver。执行该步骤并等待片刻后，

ps-ef

应显示

kube-apiserver

正在运行。这将在端口127.0.0.1:8080上提供服务，然后kubelet将与之对话。@EricTune如果您是指命令

kubectl运行kubernetes bootcamp--image=gci.io/google samples/kubernetes bootcamp:v1--port=8080

，这是在遇到此问题之前的一节中完成的。我没有在OP中遇到这个问题，但类似的问题
