我也有这个问题。事实证明，我使用的是免费层，并试图在私有存储库中推送多个图像。将一张图片设为私有，其余的设为公共，这对我来说很管用。

有一个docker文件，要求是立即构建一个映像并将其推送到docker hub

登录Docker集线器 Sudo docker login -u your_username 输入密码 构建映像 Sudo docker build -t your_username/demorepo:1.0 上面没有提到图像名称，因为your_username/demorepo是一个 在docker中心回购。标签名称为1.0 推送图片 Sudo docker推送your_username/demorepo:1.0

将已经存在的图像推送到Docker中心

Login to the Docker hub sudo docker login -u your_username Enter password Tag your image(suppose your image is named as test_docker:1.0) sudo docker tag test_docker:1.0 your_username/demorepo:firstpush Above, firstpush is the tag name given to your image, test_docker with 1.0 Tag. IMPORTANT : (While tagging, the image name is not mentioned) Now in docker images you will have 2 images, one says test_docker 1.0 and the other your_username/demorepo firstpush Push the image sudo docker push your_username/demorepo:firstpush

我也有这个问题，我测试了这里的解决方案，但无济于事，我已经正确登录，至少根据docker登录的输出，但我仍然无法推送图像。最终奏效的方法很简单:

码头工人注销

然后docker登录，就这么简单。我不知道发生了什么，但强迫重新登录起作用了。

重命名图像为用户名/image-name dockerhub-username/some-name:your-tag(例如:latest)

修改图像名称为"username"/"image_name"
