我已经安装了 minikube 并启动了它内置的 Kubernertes 集群

$ minikube start
Starting local Kubernetes cluster...
Kubernetes is available at https://192.168.99.100:443.
Kubectl is now configured to use the cluster.

我也安装了 kubectl

$ kubectl version
Client Version: version.Info{Major:"1", Minor:"3", GitVersion:"v1.3.0", GitCommit:"283137936a498aed572ee22af6774b6fb6e9fd94", GitTreeState:"clean", BuildDate:"2016-07-01T19:26:38Z", GoVersion:"go1.6.2", Compiler:"gc", Platform:"linux/amd64"}

但我无法成功使用 kubectl 与正在运行的 Kubernetes 集群对话

$ kubectl get nodes
Unable to connect to the server: net/http: TLS handshake timeout

要让它在代理后面运行，您需要设置与文档稍有不同的东西。一种。您需要确保与 VM 一起运行的 docker 守护程序可以通过代理访问 Internet。湾。您需要确保在主机上运行的 kubectl 无需通过代理即可访问虚拟机

使用默认的 kubectl 示例

  1. 确保将代理传递到由 minikube 创建的 VM 中（这可以确保 VM 中的 docker daemon 可以访问 Internet）

minikube start --vm-driver="kvm" --docker-env="http_proxy=xxx" --docker-env="https_proxy=yyy" start

注意：将 xxx 和 yyy 替换为您的代理设置

  1. 获取 VM 在启动时获取的 IP。

minikube ip

注意：每次设置 minikube 时都需要这样做，因为它可以更改

  1. 确保 kubectl 可以与此 VM 对话，而无需通过代理

export no_proxy="127.0.0.1,[minikube_ip]"

  1. 现在启动 POD 并对其进行测试

kubectl run hello-minikube --image=gcr.io/google_containers/echoserver:1.4 --port=8080

kubectl expose deployment hello-minikube --type=NodePort

kubectl get pod

curl $(minikube service hello-minikube --url)

虽然，这是一个老问题，但在这里回答，以便它可以帮助其他人面临这个问题。

我遇到了错误，因为 minikube VM 分配的内存不足。增加 RAM 应该可以解决这个问题。

Unable to connect to the server: net/http: TLS handshake timeout

minikube VM 默认配置为仅使用 2gb 内存。您可以在 minikube 启动期间使用 --memory 标志更改此值。需要 Minikube 停止、删除并重新启动

在公司代理后面，设置环境变量如下：

export HTTP_PROXY=http://<proxy hostname:port>
export HTTPS_PROXY=https://<proxy hostname:port>
export NO_PROXY=localhost,127.0.0.1,10.96.0.0/12,192.168.99.0/24,192.168.39.0/24

进而：

minikube start
