无法在Windows 10上复制到Windows容器('docker cp') [英] Unable to copy to Windows container ('docker cp') on Windows 10

问题描述

我在笔记本电脑上为Windows设置了Docker，并在Docker的设置中从 Linux容器切换到 Windows容器(这提示了几次重新启动和Windows更新).我使用以下命令拉出图像并运行基于该图像的容器:

I set up Docker for Windows on my laptop and switched from Linux Containers to Windows Containers in Docker's settings (which prompted a couple of restarts and Windows updates). I pulled an image and ran a container based on it using the commands:

docker pull microsoft/dotnet-framework
docker run -it microsoft/dotnet-framework cmd

在第二个终端窗口中，我执行了命令:

In a second terminal window, I executed the command:

docker cp app container_id:/

并收到以下错误消息:

守护程序的错误响应:不支持针对正在运行的Hyper-V容器的文件系统操作

Error response from daemon: filesystem operations against a running Hyper-V container are not supported

我搜索了此错误，但是没有(解释性的)出现，非常令人惊讶.有什么方法可以在Windows 10上将图像作为Windows容器而不是Hyper-V容器运行?

I googled this error, but nothing (explanatory) came up, quite surprisingly. Is there a way I can run the image as a Windows container rather than a Hyper-V container, on Windows 10?

最终，我会将这个容器部署到Windows Server 2016主机上，但是我需要在运行Windows 10 Pro的笔记本电脑中进行所有开发和测试.

Ultimately, I will deploy this container to a Windows Server 2016 host, but I need to do all development and testing in my laptop running Windows 10 Pro.

推荐答案

基于@GregorySuvalian的评论，我了解Windows 10仅允许Hyper-V运行时.因此，我的解决方法是停止容器，运行docker cp命令，然后重新启动容器. (我更喜欢设置音量，因为它只是一次操作.)

Based on a comment by @GregorySuvalian, I understand that Windows 10 allows Hyper-V runtime only. So my workaround is to stop the container, running the docker cp command and restart the container. (I preferred this over setting up a volume, since it is just a one time operation.)
