rancher平台上强制删除pod服务操作

背景：

在日常paas平台运维工作中需要对rancher平台进行巡检的工作，在巡检时发现在rancher管理界面无法删除异常的pod服务，

 

处理：

像这样的情况就是k8s集群的pod无法通过默认的方式去删除掉pod服务，这时候只能是手工强制性去删除pod服务。

注：rancher平台怎么切换到kubelet命名行界面指导：

 

 

 强制删除pod服务，有两种方式：

方式一：

先查询出来需要强制删除掉pod服务，然后再执行强制删除。

查询： 

> kubectl get pods -n dit-sup  | grep Terminating
dit-sup-upload-6fd555686c-zxz9h       1/1     Terminating   0          167d

强制删除：

> kubectl delete pod dit-sup-upload-6fd555686c-zxz9h --force --grace-period=0 -n dit-sup
warning: Immediate deletion does not wait for confirmation that the running resource has been terminated. The resource may continue to run on the cluster indefinitely.
pod "dit-sup-upload-6fd555686c-zxz9h" force deleted

方式二：

查询出来整个集群所有异常的pod服务，然后一次性全部删除掉

查询： 

> kubectl get pod -A |egrep -v "Run|Completed|Crea|NAMESPACE|NAME" |awk '{print $1,$2}'
ness-portal ness-portal-reservoir-7d8b49f6-h6xv4
default intake-project2-646df8d457-p7jlg
vwts cloud-platform-buiness-54b546577c-xlpwq

删除：

> kubectl get pod -A |egrep -v "Run|Completed|Crea|NAMESPACE|NAME" |awk '{print $1,$2}'|xargs -n2 kubectl delete pod  --grace-period=0  --force -n
warning: Immediate deletion does not wait for confirmation that the running resource has been terminated. The resource may continue to run on the cluster indefinitely.
pod "ness-portal-reservoir-7d8b49f6-h6xv4" force deleted
warning: Immediate deletion does not wait for confirmation that the running resource has been terminated. The resource may continue to run on the cluster indefinitely.
pod "intake-project2-646df8d457-p7jlg" force deleted
warning: Immediate deletion does not wait for confirmation that the running resource has been terminated. The resource may continue to run on the cluster indefinitely.
pod "cloud-platform-buiness-54b546577c-xlpwq" force deleted

 验证：

> kubectl get pod -A |egrep -v "Run|Completed|Crea|NAMESPACE|NAME" |awk '{print $1,$2}'

总结：

在日常的paas平台运维工作，会经常遇见大量的pod运行异常的情况，也存在对pod服务进行强制删除的操作，可以参考如上的。
