使用kubeconfig优先级顺序

1. --kubeconfig参数
2. $KUBECONFIG环境变量
3. ${HOME}/.kube/config文件

查看kubeconfig内容

kubectl config view --raw

合并多个kubeconfig

mv ~/.kube/config ~/.kube/config.bak
export KUBECONFIG=~/.kube/config:test-kubeconfig
kubectl config view --flatten > res-kubeconfig
unset KUBECONFIG
mv res-kubeconfig ~/.kube/config
