从主机推送 docker 映像（成功登录后）时，我收到“未经授权：需要身份验证”。
详细信息如下。
-bash-4.2# docker login --username=asamba [email protected]
WARNING: login credentials saved in /root/.docker/config.json
*Login Succeeded*
-bash-4.2#
-bash-4.2# docker push asamba/docker-whale
Do you really want to push to public registry? [y/n]: y
The push refers to a repository [docker.io/asamba/docker-whale] (len: 0)
faa2fa357a0e: Preparing
unauthorized: authentication required
- Docker版本：1.9.1（客户端和服务器）
-
http://hub.docker.com也创建了存储库（asamba/docker-whale）。
/var/log/messages 显示 403，我不知道这个 docker.见下文。

感谢任何帮助，如果您需要更多信息，请告诉我。我也用 -f 进行了推送。没有运气！
您需要登录 Docker。
第1步：登录docker hub
根据 @KaraPirinc 的评论，在 Docker 版本 17 中为了登录：
docker login -u username --password-stdin
然后在询问时输入您的密码。
步骤2：在中创建存储库码头枢纽.
咱们说“sql服务器：sql".
docker push <user username>/mysqlserver:sql
