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.
bash-3.2$
怎么了?
2016年8月更新
使用Docker for Mac(版本1.12.0)时，看到了表单的问题:
➜ docker pull node
Using default tag: latest
Pulling repository docker.io/library/node
Network timed out while trying to connect to https://index.docker.io/v1/repositories/library/node/images. You may want to check your internet connection or if you are behind a proxy.`enter code here`
这个问题通过更新我的MacBook Pro无线网络设置来解决，以包括以下DNS条目:8.8.8.8
欲了解更多信息，请参阅这一期(日期)，它提供了这里给出的答案。
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
如果您落后于代理，请使用以下命令
sudo mkdir /etc/systemd/system/docker.service.d
sudo cd /etc/systemd/system/docker.service.d
sudo vi http-proxy.conf
(服务)
环境= HTTP_PROXY = http://proxy-server-ip:端口”“NO_PROXY = localhost, 127.0.0.1”
Sudo systemctl daemon-reload
sudo systemctl show——property=环境docker
Sudo systemctl restart docker
如果你能获取最新的ubuntu，试试这个
sudo docker run -it ubuntu bash
无法在本地找到映像ubuntu:latest

它终于为我工作了:)
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
