【解决】Pod 状态一直 Terminating，Need to kill Pod

标签：grep   uber   容器   fir   bee   warning   min   message   scm   

偶然查看服务时发现有个单副本的 pod 一直处于Terminating状态，已达 8 天之久，且手动删除删除不掉

[appuser@lyj 2019-09-20 14:35:36 ~]$ kubectl get pods -n sit |grep loan-after-query-service-sit
loan-after-query-service-sit-868758d5c8-7sfcr    1/1       Running   0          14m
loan-after-query-service-sit-868758d5c8-scmfx    1/1     Terminating   0          8d

使用命令kubectl describe pod loan-after-query-service-sit-868758d5c8-scmfx -n NAMESPACE查看该 pod的描述信息, 得到如下

Events:
  Type    Reason   Age                 From                                        Message

这个问题是Kubernetes偶发的BUG，使用以下命令强制删除：

kubectl delete pod xxxxxx --grace-period=0 --force

执行命令后返回一条警告信息---> 警告:立即删除并不等待正在运行的资源已被终止的确认。资源可以无限期地继续在集群上运行。

[appuser@lyj 2019-09-20 14:24:34 ~]$ kubectl delete pods loan-after-query-service-sit-868758d5c8-scmfx -n NAMESPACE --grace-period=0 --force
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 "loan-after-query-service-sit-868758d5c8-scmfx" deleted

去到容器所在 Node机器上通过 docker ps 仍看得到这个已经运行 8 天的容器

手动删除该容器

[root@iz2ze0dg85eb6vxi1t0vcrz ~]# docker rm -f k8s_loan-after-query-service_loan-after-query-service-sit-868758d5c8-scmfx_sit_efeb3399-d462-11e9-aee8-00163e082a66_0
