Kubernetes API pod 拒绝连接
Kubernetes API pod refuses connection
我目前正在尝试使用 CoreOS 和 Kubernetes 设置一个小型集群。要开始，我正在按照教程的 this tutorial. I have three CoreOS machines running on VirtualBox, using vagrant. I reached the second step 进行操作，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，而是先尝试连接到它。
当我输入 curl http://127.0.0.1:8080/version 时，我得到 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 查看发生了什么荚。我该如何解决这个问题？

我手动执行了 docker 命令并得到了以下结果：

您将在下一步中设置 apiserver。它是服务于 127.0.0.1:8080 的东西。一旦 apiserver 启动，kubelet 应该停止抱怨。您提到的 curl 命令在那时也应该有效。
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。这为我提供了一个工作设置。
