删除报错
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.
Error from server (Conflict): Operation cannot be fulfilled on namespaces "etcd": The system is ensuring all content is removed from this namespace. Upon completion, this namespace will automatically be purged by the system
查看namespace,状态为terminating
解决方式：
1.在master节点上启动proxy
kubectl proxy --port=8009
2.执行删除命令
ns=etcd
curl -X PUT --data-binary @<(kubectl get namespace $ns -o json | sed 's/"kubernetes"//g') -H "Content-Type: application/json" http://127.0.0.1:8009/api/v1/namespaces/$ns/finalize
删除成功，再查看namespace
