如何一键把k8s中的pod信息导出到excel以便查找故障原因？

Posted 2020-11-23 futuretea

安装xsv

yay -S xsv

脚本如下：

#!/usr/bin/env bash
[[ -n $DEBUG ]] && set -x
set -eou pipefail

useage(){
  cat <<"EOF"
USAGE:
    pod2csv.sh [KUBECTL_OPTIONS]
    读取pod信息,生成以tab分隔的csv文件,以便过滤筛选.
    脚本最后的xdg-open请根据环境替换,类似excel表格软件最好
    可以对出错的pod进行分析,找到出错pod的共性
EOF
}
