我登录后想要上传自己保持的镜像。

报了denied: requested access to the resource is denied异常

需要使用 docker tag改名字

docker tag 3bd2787b9fa3 a1030907690/ubuntu:latest

上面的信息显示是拒接访问，因为tag的名字斜线前面部分a1030907690不是本人的用户名，下面把它修改为a1030907690/xxxxx就push成功。需要注意的是a1030907690是本人的docker用户名。进入docker hub网站查看，发现多了一个公共的repository。

[zzq@weekend110 ~]$ docker push a1030907690/ubuntu

把名字提交成这样的格式就成功了
