删除isti和foo的配置文件之后,namespace持续terminating状态,此时也无法再创建istio-system的namespace
namespace "istio-system" editedroot@ht:~/istio-0.8.0/install/kubernetes# kubectl get nsNAME ???????????????????STATUS ???????AGEchoerodon-devops-prod ??Active ???????21ddefault ????????????????Active ???????30dfoo ????????????????????Terminating ??11distio-system ???????????Terminating ??19djack-demo ??????????????Active ???????29dkube-public ????????????Active ???????30dkube-system ????????????Active ???????30dsock-shop ??????????????Active ???????22d
此时再删除istio-system也无法删除
root@ht:~/istio-0.8.0/install/kubernetes# kubectl delete ns istio-system
Error from server (Conflict): Operation cannot be fulfilled on namespaces "istio-system": The system is ensuring all content is removed from this namespace. ?Upon completion, this namespace will automatically be purged by the system.
好像是陷入死循环一样
此时查看pod，发现本应该已经被删除的istio系列pod依旧还出现在系统中，并且处于unknowed状态，失联了？
root@ht:~/istio-0.8.0/install/kubernetes# kubectl get pod -n istio-system ?????????????????????????NAME ???????????????????????????????????????READY ????STATUS ???RESTARTS ??AGEistio-ingressgateway-6bc7c7c4bc-zwqmn ??????1/1 ??????Unknown ??0 ?????????19distio-statsd-prom-bridge-6dbb7dcc7f-44gzv ??1/1 ??????Unknown ??0 ?????????19distio-telemetry-54b5bf4847-rn9qj ???????????2/2 ??????Unknown ??0 ?????????19d

推测问题可能出在这
此时用kubetl delete -f 普通删除没有响应，故接下来采用强制删除
root@ht:~/istio-0.8.0/install/kubernetes# kubectl delete pod -n istio-system istio-ingressgateway-6bc7c7c4bc-zwqmn --grace-period=0 --forcewarning: Immediate deletion does not wait for confirmation that the running resource has been terminated.

一开始还是出现terminating的状态，等待一会后就会发现系统恢复正常
root@ht:/etc/kubernetes# kubectl get ns -o wideNAME ???????????????????STATUS ???AGEchoerodon-devops-prod ??Active ???21ddefault ????????????????Active ???30djack-demo ??????????????Active ???29dkube-public ????????????Active ???30dkube-system ????????????Active ???30dsock-shop ??????????????Active ???22d
Kubernetes删除namespace后持续terminating状态
