我试图让事情自动化。我有一个PowerShell脚本，它将启动Amazon实例并安装docker.i能够登录到Docker登录但无法提取图像。当我从Windows PowerShell命令行执行此操作时，它工作得很好，但是当我在脚本中执行它时，它只是无法工作。请找到下面的脚本。
"$ Docker Login"
$DOCKER_USER="xxxx"
$DOCKER_PASS="xxxx"
docker login --username=$DOCKER_USER --password=$DOCKER_PASS
docker pull赢了工作，它就像这样挂起：

请帮我使用PowerShell脚本，该脚本将从Windows机器上的docker hub中提取图像。 对此有任何建议会有所帮助。提前致谢
答案 0 :(得分：0)
我使用这个脚本来标记我的图像......它有效。
$account = "myusername"
$reponame = "myreponame"
$version = "2.0.0"
$latest = $account + "/" + $reponame + ":latest"
$newest = $account + "/" + $reponame + ":" + $version
docker pull $latest
docker tag $latest $newest
docker push $newest
docker push $latest
尝试在Windows CMD中运行命令。在使用Docker for Windows时，我体验过Powershell显示的信息较少。
