docker is configured to use the default machine with IP 192.168.99.100
For help getting started, check out the docs at https://docs.docker.com
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?
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
