问题

K8S上出现大量持续terminating的Pod，无法通过常规命令删除。需要编写脚本批量强制删除持续temminating的Pod：contribution-xxxxxxx。

解决

1. 获取terminating状态的pod名称的命令：

# 获取media命名空间下，名称带contribution，运行状态除了正常Runing的Pod信息，并只打印第一列Pod名称。
kubectl get pod -n media |grep contribution|grep -v Running|awk '{print $1}'

2. 强制删除pod的命令：

# 强制删除media命令空间下，名为 contribution-7d57bdb6d7-krksf的Pod。
kubectl delete pods contribution-7d57bdb6d7-krksf --grace-period=0 --force -n media

3. 编写脚本对大量terminating的同名容器强制删除：

vim 72_ForceDeleteTerminatingPods.sh

脚本具体内容如下：

#!/bin/bash
for POD in `kubectl get pod -n media |grep contribution|grep -v Running|awk '{print $1}'`
do
    kubectl delete pods ${POD} --grace-period=0 --force -n media
done

4. 执行结果

[sysma@prod-k8s-0001 ~]$ chmod +x 72_ForceDeleteTerminatingPods.sh 
[sysma@prod-k8s-0001 ~]$ ./72_ForceDeleteTerminatingPods.sh
