windows玩docker的时候，经常碰到这种问题：

　　Error response from daemon: Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)

　　Error response from daemon: Get https://registry-1.docker.io/v2/openstf/stf/manifests/latest: Get https://auth.docker.io/token?scope=repository%3Aopenstf%2Fstf%3Apull&service=registry.docker.io: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)

原因是因为连接国内下Docker镜像速度缓慢超时，很正常，歪果仁就是这么的不友好
