powershell - 无法从Docker Hub提取图像

Question

我正在尝试使事情自动化。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登录名但无法提取图像。当我从Windows PowerShell命令行执行此操作时，它可以正常工作，但是当我在脚本中执行此操作时，它将不起作用。请在下面找到脚本。

"$ Docker Login"
$DOCKER_USER="xxxx"
$DOCKER_PASS="xxxx"
docker login --username=$DOCKER_USER --password=$DOCKER_PASS

docker pull将无法正常工作，而是像这样挂起:

请帮助我使用PowerShell脚本，该脚本将从Windows计算机上的docker hub中提取图像。
关于此的任何建议将有所帮助。提前致谢

Answer 1

我使用此脚本来标记我的图像。

$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。我经验丰富的Powershell在使用Docker for Windows时显示较少的信息。
