这可能是特定于DigitalOceans容器注册表，但它可能有帮助:

在我的例子中，我的管道在docker推送之后触发了一个清理作业(doctl注册表垃圾收集启动)，这将注册表置于只读模式(参见doc)。因此，在清理作业处于活动状态时的下一个推送将被拒绝:对资源的请求访问将被拒绝。

如果doctl注册表垃圾收集get-active返回404，则作业完成，docker推送将成功完成。

您可能需要在docker push之前将docker repo切换为private。

感谢Dean Wu提供的答案和ses的评论，在推送之前，请记得注销，然后从命令行登录到您的docker hub帐户

# you may need log out first `docker logout` ref. https://stackoverflow.com/a/53835882/248616
docker login

根据文件:

You need to include the namespace for Docker Hub to associate it with your account.
The namespace is the same as your Docker Hub account name.
You need to rename the image to YOUR_DOCKERHUB_NAME/docker-whale.

所以，这意味着你必须在推送之前标记你的图像:

docker tag firstimage YOUR_DOCKERHUB_NAME/firstimage

然后你就可以推它了。

docker push YOUR_DOCKERHUB_NAME/firstimage

我也有同样的问题。在我的情况下，我登录在index.docker.io，并将图像推到docker.io/username/image:标签。

解决方案是在docker中登录。IO通过运行这个命令:

export CI_REGISTRY=docker.io
docker login -u "$CI_REGISTRY_USER" -p "$CI_REGISTRY_PASSWORD" $CI_REGISTRY
docker push USERNAME/IMAGE:TAG

输出为:

The push refers to repository [docker.io/USERNAME/IMAGE:TAG] eeb7e16c6369: Preparing 6bd09f46d0ae: Preparing f5a7f7a3fb28: Preparing 07952c1df7f6: Preparing a4522c0d203b: Preparing 3e207b409db3: Preparing 3e207b409db3: Waiting a4522c0d203b: Layer already exists 3e207b409db3: Layer already exists f5a7f7a3fb28: Pushed 6bd09f46d0ae: Pushed 07952c1df7f6: Pushed eeb7e16c6369: Pushed latest: digest: sha256:7ce256fa83ef1eebcaaaa460c4d73f87f2adf304bc6e6c1b83a19d987cd61ad5 size: 1579 Running after_script 00:02 Saving cache 00:01 Uploading artifacts for successful job 00:02 Job succeeded

的问候。

如果您已经登录，如果您仍然得到错误。请按照步骤操作，

PS C:\Users\rohit\Docker> docker logout

从应用程序登录。我一直在尝试从终端没有运气。

这是版本17.06.1

当我在标记图像时使用docker中心名时，它为我工作。(这里，xyz是一个docker中心名)

# Login to docker hub account 
docker login 

# tag image 
docker tag nginx xyz/nginx

# push image
docker push xyz/nginx
