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

docker is configured to use the default machine with IP 192.168.99.100

bash-3.2$
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.
bash-3.2$
怎么了?
在Windows 7上，如果你认为你落后于代理
Logon to default machine
$ docker-machine ssh default
Update profile to update proxy settings
docker@default:~$ sudo vi /var/lib/boot2docker/profile
Append from the below as appropriate
# replace with your office's proxy environment
export"HTTP_PROXY=http://PROXY:PORT"
export"HTTPS_PROXY=http://PROXY:PORT"
# you can add more no_proxy with your environment.
export"NO_PROXY=192.168.99.*,*.local,169.254/16,*.example.com,192.168.59.*"
Exit
docker@default:~$ exit
Restart docker machine
docker-machine restart default
Update environment settings
eval $(docker-machine env default)
以上步骤略有调整，但请参见故障排除指南:https://docs.docker.com/toolbox/faqs/troubleshoot/#/update-varlibboot2dockerprofile-on-the-docker-machine
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
