Kubectl：帶有 minikube 的 Kubernetes 超時

Question

我已經安裝了 minikube 並啟動了它內置的 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.

我也安裝了 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"}

但是我無法成功使用 kubectl 與正在運行的 Kubernetes 集群通話

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

Answer 1

要讓它在代理后面運行，您需要設置與文檔略有不同的東西。 一個。 您需要確保與VM一起運行的docker守護程序可以通過代理連接到Internet。 灣 您需要確保在主機上運行的kubectl可以在不通過代理的情況下到達VM

使用默認的kubectl示例

1. 確保將代理傳遞到由minikube創建的VM（這可確保VM中的docker守護程序可以訪問Internet）

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

注意：使用代理設置替換xxx和yyy

2. 獲取VM在啟動時獲得的IP。

minikube ip

注意：每次設置minikube都需要這樣做，因為它可以改變

3. 確保kubectl可以在不進入代理的情況下與此VM通信

export no_proxy="127.0.0.1,[minikube_ip]"

4. 現在啟動POD並測試它

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)

Answer 2

雖然，這是一個老問題，但在這里回答，以便它可以幫助其他人面對這個問題。

我得到了以下錯誤，因為minikube VM缺少已分配的內存。增加RAM應解決此問題。

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

默認情況下，minikube VM配置為僅使用2gb內存。 您可以在minikube start期間使用--memory標志更改此值。 Minikube將需要停止，刪除並重新開始

Answer 3

在公司代理背后，設置如下環境變量：

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

然后：

minikube start

為了在 Windows 上解決它，我去了 hyper v manager 並為我創建的 minikube 增加了虛擬機的內存
