我刚刚在他们的网页上安装了Docker-Toolbox
我从Docker快速入门终端开始，如下所示

但当我尝试执行docker拉hello-world时，这是我看到的
bash-3.2$ docker run hello-world
Unable to find image 'hello-world:latest' locally
Pulling repository docker.io/library/hello-world
Network timed out while trying to connect to https://index.docker.io/v1/repositories/library/hello-world/images. You may want to check your internet connection or if you are behind a proxy.

怎么了?
我昨天遇到了这个完全相同的问题，没有一个“流行”的答案(比如将DNS修复到8.8.8.8)对我有效。我最终偶然发现了这个链接，这就成功了……https://github.com/docker/for-win/issues/16
在Docker for Windows, Windows 10和Hyper-V之间，在虚拟网络适配器创建过程中似乎有一个问题。具体来说，您可能最终会得到两个“vEthernet (DockerNAT)”网络适配器。使用Get-NetAdapter“vEthernet (DockerNAT)”检查(在一个升高的PowerShell控制台)。如果结果显示了多个适配器，您可以禁用并重命名它:
$vmNetAdapter = Get-VMNetworkAdapter -ManagementOS -SwitchName DockerNAT
Get-NetAdapter "vEthernet (DockerNAT)" | ? { $_.DeviceID -ne $vmNetAdapter.DeviceID } | Disable-NetAdapter -Confirm:$False -PassThru | Rename-NetAdapter -NewName "OLD"
然后打开Device Manager并删除禁用的适配器(出于某种原因，可以从这里执行，但不能从Network and Sharing Center适配器视图执行)。
我猜您有网络问题。你背后有代理人吗?它是否有可能过滤到docker的连接。IO或阻塞docker用户代理?
我安装了工具箱，运行了你的测试。它工作得很好，在这里:

Hello from Docker.
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
