[root@xiaoyequ /]# docker push xiaoyequ666/diytomcat:1.0
The push refers to repository [docker.io/xiaoyequ666/diytomcat]
An image does not exist locally with the tag: xiaoyequ666/diytomcat

问题：本地镜像名无帐号信息，解决加 tag即可

docker tag cfae60a041a3 xiaoyequ666/tomcatofxiaoyequ:1.0 

注意：斜杠前面的要和用户名一致（xiaoyequ666）

 再次 push， ok
