1.首先安装kubectl

1.1验证自己系统

uname -m

1.2

按照步骤安装

在 Linux 系统中安装并设置 kubectl | Kubernetes

1.3 阿里云配置

通过kubectl连接Kubernetes集群_容器服务 Kubernetes 版 ACK(ACK)-阿里云帮助中心

2.验证

阿里云config直接导出，直接扔到.kube/ 位置也行

mkdir ~/.kube/
cd ~/.kube/
vim config
kubectl get node,pod,svc

3.1 多config配置

//合并配置
KUBECONFIG=$HOME/.kube/config_latest:$HOME/.kube/config_qa kubectl config view --merge --flatten > config
//永久生效
echo 'export KUBECONFIG=$HOME/.kube/config' >> ~/.bashrc                                      
source ~/.bashrc//查看当前配置
kubectl config current-context
kubectl config get-contexts

3.2 合成config事例
