23、orphaned pod处理

参考
https://www.cnblogs.com/wiseo/p/13164215.html

一、处理 K8S Orphaned pod found - but volume paths are still present on disk 孤儿pod

查看kubelet或/var/log/messages日志一直包错，发现是孤儿pod，是由于其pod被删除后存储路径还保存在磁盘。

二、解决办法

• 根据/var/log/{messages,syslog}或kubelet报错，查找孤儿pod
• 通过mount命令查找孤儿pod的挂载
• 卸载孤儿pod的存储挂载
• 删除/var/lib/kubelet/pods下孤儿pod的存储路径

三、处理脚本

vim /usr/local/bin/RemoveOrphancePods.sh
:set paste
i
#!/bin/sh
orphanedPods=`cat /var/log/{messages,syslog} 2>/dev/null |grep 'orphaned pod'|awk -F '"' '{print $2}'|uniq`;
orphanedPodsNum=`echo $orphanedPods|awk -F ' ' '{print NF}'`;
echo -e "orphanedPods: $orphanedPodsNum \n$orphanedPods";
for i in $orphanedPods
do
echo "Deleting Orphaned pod id: $i";
rm -rf /var/lib/kubelet/pods/$i;
done
chmod +x /usr/local/bin/RemoveOrphancePods.sh
RemoveOrphancePods.sh
