修改标签以及上传

记得将标签修改为自己的

[root@hydra ~]# docker tag k8s.gcr.io/kube-scheduler:v1.13.0 fakehydra/kube-scheduler:v1.13.0
[root@hydra ~]# docker push fakehydra/kube-scheduler:v1.13.0
The push refers to repository [docker.io/fakehydra/kube-scheduler]
f6c506417998: Pushed 
5fe6d025ca50: Mounted from fakehydra/kube-proxy 
v1.13.0: digest: sha256:b872e56acf54c9e594922544f368c1acfd2381b7d9b71b03e4470e3954405b58 size: 741

重点：注册账号、修改标签、上传

可能会遇到的错误：标签没打对或者没有加上版本号
