kubernetes删除Namespace出现Terminating状态

namespace删除不了

[root@kubesphere ~]# kubectl get ns
NAME              STATUS        AGE
default           Active        3h
kube-node-lease   Active        3h
kube-public       Active        3h
kube-system       Active        3h
rbd-system        Terminating   108m

一直Terminating这个生态

# 1
kubectl proxy --port=8081

# 2 开启另外一个终端
cat <<EOF | curl -X PUT \
  localhost:8081/api/v1/namespaces/rbd-system/finalize \

  --data-binary @-

}

rbd-system替换成需要删除的namespace

结果

[root@kubesphere ~]# kubectl get ns
NAME              STATUS   AGE
default           Active   3h1m
kube-node-lease   Active   3h1m
kube-public       Active   3h1m
kube-system       Active   3h1m
