Kubectl:带有 minikube 的 Kubernetes 超时
Kubectl: Kubernetes with minikube times out
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

但我无法成功使用 kubectl 与 运行 Kubernetes 集群通信
$ kubectl get nodes

要在代理后面 运行 获取它,您需要设置与文档略有不同的设置。
一种。您需要确保 docker 守护程序 运行 VM 可以通过代理访问互联网。
b.您需要确保主机上的 kubectl 运行 可以在不通过代理
的情况下访问 VM
使用默认的 kubectl 示例
- 确保将代理传递到由 minikube 创建的 VM(这确保 VM 中的 docker 守护程序可以访问互联网)
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
- 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,因为它可能会发生变化
- 确保 kubectl 可以在不通过代理的情况下与该 VM 通信
export no_proxy="127.0.0.1,[minikube_ip]"
- 现在启动 POD 并进行测试
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)
虽然是个老问题了,但在这里回答一下,希望对其他遇到这个问题的人有所帮助。
我遇到了以下错误,因为 minikube VM 内存不足 allocated.Increasing 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,像这样设置环境变量:
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
