有两种选择:

Go into the hub, and create the repository first, and mark it as private. Then when you push to that repo, it will be private. This is the most common approach. log into your docker hub account, and go to your global settings. There is a setting that allows you to set what your default visability is for the repositories that you push. By default it is set to public, but if you change it to private, all of your repositories that you push will be marked as private by default. It is important to note that you will need to have enough private repos available on your account, or else the repo will be locked until you upgrade your plan.

dockerhub中还有一个“默认隐私”设置。访问https://hub.docker.com/settings/default-privacy或点击帐户设置->默认隐私。

将切换设置为“private”。

这不是一个完整的解决方案，但至少默认的私有比默认的公共要好。你可以返回并公开你想要的。

首先，你需要用你的注册主机正确地标记你的图像:

docker tag [OPTIONS] IMAGE[:TAG] [REGISTRYHOST/][USERNAME/]NAME[:TAG]

然后docker push使用相同的标签。

docker push NAME[:TAG]

例子:

docker tag 518a41981a6a myRegistry.com/myImage
docker push myRegistry.com/myImage

如果有人正在寻找一种快速将所有图像推送到私有存储库的方法， 你可以使用我的bash脚本-它会将所有Docker映像推送到新的私有注册表:

#!/bin/bash

repo="<change_to_your_new_repo>"
remote_repo="<the_new_repo_name>"

for img in $(docker images --format "{{.Repository}}:{{.Tag}}")
do
        image=$(echo $img | cut -d ":" -f 1)
        image_tag=$(echo $img | cut -d ":" -f 2)

        docker image tag $image:$image_tag $repo/$remote_repo/$image:$image_tag
        docker image push $repo/$remote_repo/$image:$image_tag

        docker rmi $repo/$remote_repo/$image:$image_tag
done

首先登录您的私有存储库。

> docker login [OPTIONS] [SERVER]

[OPTIONS]: 
-u username 
-p password

eg:

> docker login localhost:8080

然后为您的私有存储库标记您的映像

> docker tag SOURCE_IMAGE[:TAG] TARGET_IMAGE[:TAG]

eg:

> docker tag myApp:v1 localhost:8080/myname/myApp:v1

最后将您的标记图像推到您的私有存储库

>docker push [OPTIONS] NAME[:TAG]

eg:

> docker push localhost:8080/myname/myApp:v1
