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
[email protected]:~/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

此时再删除istio-system也无法删除

[email protected]:~/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？

[email protected]:~/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
[email protected]:~/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

[email protected]:~/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. The resource may continue to run on the cluster indefinitely.
pod "istio-ingressgateway-6bc7c7c4bc-zwqmn" deleted

[email protected]:~/istio-0.8.0/install/kubernetes# kubectl delete pod -n istio-system istio-telemetry-54b5bf4847-rn9qj  --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 "istio-telemetry-54b5bf4847-rn9qj" deleted
[email protected]:~/istio-0.8.0/install/kubernetes# kubectl delete pod -n foo httpbin-68fbcdcfc7-xbf2c --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 "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

[email protected]:/etc/kubernetes# kubectl get ns -o wide
NAME                    STATUS    AGE
choerodon-devops-prod   Active    21d

jack-demo               Active    29d
kube-public             Active    30d
kube-system             Active    30d
sock-shop               Active    22d
