我在代理服务器后面，按照此处列出的“使用Vagrant＆amp; CoreOS安装Kubernetes”步骤进行操作：https://coreos.com/kubernetes/docs/latest/kubernetes-on-vagrant.html
完成安装后，当我运行
时$ kubectl get nodes
我收到了错误。
Unable to connect to the server: Service Unavailable
e1，c1和w1已经启动，我可以发出$ vagrant ssh。
当我检查w1时，我看到docker服务没有运行时出现下面列出的错误。

我猜这个问题是因为我在代理后面。在运行安装步骤之前，我发出命令
$export "HTTP_PROXY=http://http-proxy.xxxxxx.com:8080"
$export "HTTPS_PROXY=http://http-proxy.xxxxxx.com:8080"
$export "http_proxy=http://http-proxy.xxxxxx.com:8080"
$export "https_proxy=http://http-proxy.xxxxxx.com:8080"
您知道这对于代理后面的安装是否足够，或者我是否需要将代理设置添加到其他地方。
提前谢谢你， turgos

您导出的变量仅在您当前的shell会话中有效，它们不适用于您的法兰绒系统单元。
在systemd单元目录中创建以下drop-in，然后用systemctl daemon-reload重新加载守护进程，它应该修复你的法兰绒问题：
/etc/systemd/system/flannel.service.d/proxy.conf：
[Service]
Environment="HTTP_PROXY=http://http-proxy.xxx:8080"
