Kubernetes API pod拒绝连接

标签： kubernetes coreos

我目前正在尝试使用CoreOS和Kubernetes设置一个小型群集。要开始使用，请关注this教程。我有三台运行在VirtualBox上的CoreOS机器，使用vagrant。我到达了教程的second step，但卡住了。

我似乎可以使用systemctl start kubelet启动kubelet，但我似乎无法连接到API服务器。似乎它没有启动API服务器，但是首先尝试连接它。

当我输入curl http://127.0.0.1:8080/version时，我会回复curl: (7) Failed to connect to 127.0.0.1 port 8080: Connection refused。

Journalctl只是告诉我kubelet正在尝试连接到API服务器，并且由于无法访问API服务器，我无法使用kubectl来查看Pod发生了什么。我应该如何解决这个问题？

修改

我手动执行了docker命令，得到了以下内容：

您将在下一步中设置apiserver。这是在127.0.0.1:8080服务的东西。一旦apiserver启动，kubelet应该停止抱怨。你提到的:h window :h :sp :h :sb :h :b :h 'hidden' :h :_% :h CTRL-W 命令也应该在那时工作。

答案 1 :(得分：0)

我现在放弃了这个设置。我认为它与ssl设置中的配置错误有关。现在我只使用this指南，结合前面提到的教程，并从配置文件中删除所有与ssl相关的东西。这给了我现在的工作设置。
