Question

我正在按照kubernetes documentation在Ubuntu 16.04中安装minkube 0.19.1。作为先决条件，我已经安装了kubectl和Oracle VirtualBox。当我用kubectl version检查kubectl时，它给出了以下内容。

Client Version: version.Info{Major:"1", Minor:"6", GitVersion:"v1.6.6", GitCommit:"7fa1c1756d8bc963f1a389f4a6937dc71f08ada2", GitTreeState:"clean", BuildDate:"2017-06-16T18:34:20Z", GoVersion:"go1.7.6", Compiler:"gc", Platform:"linux/amd64"}
The connection to the server localhost:8080 was refused - did you specify the right host or port?

但是当我netstat端口检查进程时，它没有为结果提供任何内容。我也设置了Google云端SDK。

我搜索并尝试了许多包含this的解决方案，但无法解决我的问题。

以下是我的gcloud配置和信息结果。

$gcloud config list


[compute]
zone = asia-southeast1-a
[core]
account = userName@mail.com
disable_usage_reporting = False
project = sampleproject1990

$gcloud info

有谁能告诉我如何解决这个问题？

Answer 1

我在使用Minikube和virtualbox驱动程序时遇到过类似的问题。请确保虚拟机配置的接口已启用。我做了 sudo ifconfig vboxnet0 up ，我的问题得到了解决

Answer 2

此问题是因为Kubelet未运行或运行状况不佳。

解决此问题的一种方法：

$ sudo swapoff -a
$ sudo systemctl enable kubelet
$ sudo systemctl start kubelet

在此之后，使用Kubernetes部署kubeadm，如下所示：

$ sudo kubeadm init --ignore-preflight-errors=all

加载kubeadm凭据后，如果您正在处理群集，请取消主节点并加入工作节点。

现在给出命令：

$ sudo kubectl cluster-info

服务器和客户端应该使用相同的Kubernetes版本运行。

如果此解决方案不起作用，请刮掉Kubernetes，kubectl，kubeadm和kubelet，然后单独执行this指南中的 Kubernetes安装步骤。

Answer 3

我遇到了同样的问题。原来我没有以root用户身份运行命令。因此，如果您以超级用户（sudo -i）登录，则可能会起作用。

kubectl：连接被拒绝
