Kubernetes API pod拒绝连接
Kubernetes API pod拒绝连接
提问于 2015-11-02 16:33:02
目前，我正在尝试使用CoreOS和Kubernetes来设置一个小型集群。首先，我将学习这教程。我有三台CoreOS机器运行在VirtualBox上，使用的是流浪者。我到了教程的第二步，但被卡住了。
我似乎能够使用systemctl start kubelet启动kubelet，但我似乎无法连接到API服务器。似乎没有启动API服务器，而是尝试先连接到它。
当我进入curl http://127.0.0.1:8080/version时，我会得到curl: (7) Failed to connect to 127.0.0.1 port 8080: Connection refused。
Journalctl只是向我展示了kubelet试图连接到API服务器，并且由于API服务器无法访问，所以我不能使用kubectl来查看Pod是怎么回事。我该如何处理这个问题呢？

我手动执行了docker命令，并得到了以下结果：

我暂时放弃了这个设置。我认为这与ssl设置中的错误配置有关。现在，我只是使用这指南，并结合前面的教程，从配置文件中删除了所有与ssl相关的内容。这给了我一个暂时的工作安排。

您将在下一步中设置apiserver。它是服务于127.0.0.1:8080的东西。库贝利特应该停止抱怨，一旦apiserver启动。您提到的curl命令在这一点上也应该有效。
