1、需要自行安装k9s
2、config文件放在home的.kube隐藏文件夹下

#!/bin/bash

# define log & color

readonly FG_WHITE="37"

function debug()
{
    echo -e "\033[${FG_WHITE}m${LOG_DEBUG}\033[0m $1"
}
function info(){
    echo -e "\033[${FG_GREEN}m${LOG_INFO}\033[0m $1"
}
function infoText(){

}
function warn()
{
    echo -e "\033[${FG_YELLOW}m${LOG_WARN}\033[0m $1"
}
function error()
{
    echo -e "\033[${FG_RED}m${LOG_ERROR}\033[0m $1"
}
function coloredLog()
{
    echo -e "\033[$1;$2m $3\033[0m"
}

function main() {
    order=1
    configs=$(ls -l ~/.kube/ |grep -v 'total'|awk '{print $9}')
    for config in ${configs};do
      infoText ${order} && echo -e ${config}
      let order+=1
    done
    echo -en "\033[${FG_GREEN}m${LOG_INFO}\033[0m please choose config:"
    read choostOrder

    order=1
    for config in ${configs};do
      if [[ ${order} == ${choostOrder} ]]; then
        info "chose  ${choostOrder}, use config ${config}"
        cd && echo $(pwd) && echo "exec k9s -A --kubeconfig=.kube/${config}"
        k9s -A --kubeconfig=.kube/${config}
	break
      fi
      let order+=1
    done
    
}

main

使用效果：
