刪除isti和foo的配置文件之后,namespace持續terminating狀態,此時也無法再創建istio-system的namespace
namespace "istio-system" edited root@ht:~/istio-0.8.0/install/kubernetes# kubectl get ns NAME STATUS AGE choerodon-devops-prod Active 21d default Active 30d foo Terminating 11d istio-system Terminating 19d jack-demo Active 29d kube-public Active 30d kube-system Active 30d sock-shop Active 22d
此時再刪除istio-system也無法刪除
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.
好像是陷入死循環一樣
此時查看pod，發現本應該已經被刪除的istio系列pod依舊還出現在系統中，並且處於unknowed狀態，失聯了？
root@ht:~/istio-0.8.0/install/kubernetes# kubectl get pod -n istio-system NAME READY STATUS RESTARTS AGE istio-ingressgateway-6bc7c7c4bc-zwqmn 1/1 Unknown 0 19d istio-statsd-prom-bridge-6dbb7dcc7f-44gzv 1/1 Unknown 0 19d istio-telemetry-54b5bf4847-rn9qj 2/2 Unknown 0 19d
root@ht:~/istio-0.8.0/install/kubernetes# kubectl get pods -n foo NAME READY STATUS RESTARTS AGE httpbin-68fbcdcfc7-xbf2c 2/2 Unknown 0 11d
推測問題可能出在這
此時用kubetl delete -f 普通刪除沒有響應，故接下來采用強制刪除
root@ht:~/istio-0.8.0/install/kubernetes# kubectl delete pod -n istio-system istio-ingressgateway-6bc7c7c4bc-zwqmn --grace-period=0 --force warning: Immediate deletion does not wait for confirmation that the running resource has been terminated.

一開始還是出現terminating的狀態，等待一會后就會發現系統恢復正常
