kube-apiserver啓動時報錯而且不能操做etcd

kube-apiserver啓動時報錯，錯誤信息以下：

Flag --kubelet-port has been deprecated, kubelet-port is deprecated and will be removed.

此時查看etcd，也沒有/registry。通過一些參數的研究，最後發現是etcd版本的問題。

--storage-backend string                                  The storage backend for persistence. Options: 'etcd3' (default), 'etcd2'.

修改參數，再啓動kube-apiserver,能夠正常使用。搞定！
