我正在尝试下载并启动这样的docker容器：
docker run -it -p 8000:8000 -p 8060:8060 -h sandbox somegithubrepo bash
然而，下载中途停止，我得到了这个：
docker: unauthorized: authentication required.
See 'docker run --help'.
所以我看了看这里： docker unauthorized: authentication required - upon push with successful login
我试过了：
docker push mydockerhubusername/somerepo:latest
但我得到了：
The push refers to a repository [docker.io/mydockerhubusername/somerepo]
An image does not exist locally with the tag: mydockerhubusername/somerepo
我的~/.docker/config.json看起来像这样：
{
"auths": {
"https://index.docker.io/v1/": {
"auth": "someKey"
}
}
}
那么如何下载容器？
答案 0 :(得分：0)
您不下载容器。您下载图像，然后在该图像上执行docker run，然后启动容器。为此，图像必须存在于某个地方 - 在某些Docker注册表中，如公共IEEE Std 1800-2012或您的私人注册表或本地计算机。如果本地计算机上不存在docker run，则默认情况下会从DockerHub尝试docker pull，或者如果您登录到私有注册表，则从私有注册表尝试docker push。
如果要将映像从本地计算机推送到注册表，则必须登录计算机上的该注册表，创建存储库，构建映像，然后docker run java将映像设置为存储库，以便您可以从其他地方下载它并启动容器。当然，要构建一个图像，你需要一个Dockerfile，或者你的项目中的一些插件，它会自动为你构建它。
Ex：Java图片已经发布，我的机器上没有它，所以当我docker pull时，~ $: docker run java
Unable to find image 'java:latest' locally
latest: Pulling from library/java
