【Kubernetes】Kubernetes删除namespace后持续terminating状态

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" edited

root@ht:~/istio-0.8./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./install/kubernetes# kubectl get pod -n istio-system

NAME                                        READY     STATUS    RESTARTS   AGE

istio-ingressgateway-6bc7c7c4bc-zwqmn       /       Unknown             19d

istio-statsd-prom-bridge-6dbb7dcc7f-44gzv   /       Unknown             19d

istio-telemetry-54b5bf4847-rn9qj            /       Unknown             19d

root@ht:~/istio-0.8./install/kubernetes# kubectl get pods -n foo

NAME                       READY     STATUS    RESTARTS   AGE

httpbin-68fbcdcfc7-xbf2c   /       Unknown             11d

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./install/kubernetes# kubectl delete pod -n istio-system istio-ingressgateway-6bc7c7c4bc-zwqmn --grace-period= --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 "istio-ingressgateway-6bc7c7c4bc-zwqmn" deleted

root@ht:~/istio-0.8./install/kubernetes# kubectl delete pod -n istio-system istio-statsd-prom-bridge-6dbb7dcc7f-44gzv  --grace-period= --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 "istio-statsd-prom-bridge-6dbb7dcc7f-44gzv" deleted

root@ht:~/istio-0.8./install/kubernetes# kubectl delete pod -n istio-system istio-telemetry-54b5bf4847-rn9qj  --grace-period= --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 "istio-telemetry-54b5bf4847-rn9qj" deleted

root@ht:~/istio-0.8./install/kubernetes# kubectl delete pod -n foo httpbin-68fbcdcfc7-xbf2c --grace-period= --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 "httpbin-68fbcdcfc7-xbf2c" deleted

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 wide

NAME                    STATUS    AGE

choerodon-devops-prod   Active    21d

default                 Active    30d

jack-demo               Active    29d

kube-public             Active    30d

kube-system             Active    30d

sock-shop               Active    22d
